COMPREHENSIVE EXAM QUESTIONS IN RESEARCH METHODS(1)
1 PHILOSOPHY LOGIC AND ETHICS OF SCIENCE
A) General
A1 Starbuck has suggested that the properties shared by all organizations ought to be uninteresting
and unimportant He also notes that although statements about averages bother very few they
ought to bother many (Journal of Management Studies vol 30(6) 1993)
Do you agree with these statements If so why and what are the implications of your beliefs for
research methods in strategic management and organization science If not why not and what
are the implications of your beliefs for research methods in those areas
TH
A2 Lay out the components of the Runkel and McGrath (1972) Research Cycle and the Martin
(1982) Garbage Can Model of the research process What are the aims of either approach What
assumptions does each approach make What basic themes does each approach emphasize
What kinds of constraints on the process of doing research does each approach highlight How
are the two approaches alike and different in other ways What are the likely pitfalls of viewing
the research process from only one of these two viewpoints
A3 Define (and discuss important features or issues concerning) the following constructs of
Philosophy and Logic of Science (Define any four terms)
1 Null hypothesis 6 Nomological network
2 Logical empiricism (positivism) 7 Modus tollens
3 Paradigm 8 The fallacy of affirming the consequent
4 Independent variable 9 Theory
5 Operational definition
A4 Organizational Studies may be described as either a basic or an applied
discipline From your point of view is Organizational Studies a basic discipline
or an applied discipline or both What should it be When answering this
question be sure to define distinctions between these two types of disciplines
Provide evidence from the organizational studies literature that supports your
position
A5 What rules of evidence are used to determine whether a research finding is
meaningful
A6 Considerable debate in the social and behavioral sciences has occurred
concerning the role of the context of discovery versus the context of
justification Much of the debate has addressed the following sets of issues
a What features distinguish the role of discovery from the role of justification
b What is the role of discovery versus justification in the research process
c Compare the perspectives of a logical empiricist and a relativist What
distinctions would they make between the context of discovery and the context
of justification
d Can a discipline be said to progress within the context of discovery
A7 An epistemology is a set of rules for the appropriate way to generate knowledge
Outline the major components of your epistemology for Organizational Studies
research You may wish to proceed by identifying one of the established
epistemologies and comparing it to yours (eg skepticism positivism
empiricism pragmatism relativism) Describe the process by which you feel
knowledge can be generated most effectively in Organizational Studies Identify
and define the key concepts of your research philosophy and discuss its
strengths and weaknesses
A8 Abraham Kaplan argues that behavioral scientists should practice openness in
inquiry that is they should not pre-judge research or theory negatively or
positively on the basis of its content There are many other competing
philosophical schools of thought as to how empirical research should be
conducted Much of the debate has addressed the following issues
a What are the criteria for judging whether research is worthwhile Is there
some research that should not even be done
b What is the most effective model of the research process
c How does a researcher determine the meaningfulness of a research finding
That is what are the rational rules of evidence necessary for evaluating research
findings
In your doctoral studies you have been exposed to a variety of approaches for
addressing each of the above issues Please describe in detail your position on
these issues and provide citations where appropriate In addition please
highlight the major competing positions on each issue
A9 In recent years there has been considerable debate in the social and behavioral
sciences concerning the two competing epistemologies-- logical empiricism
(including falsificationism) and relativism (ie post-positivism)
a What characteristics distinguish these two epistemologies Be sure to address
both conceptual and methodological differences
b Take the perspective of a logical empiricist How would this perspective
affect the manner in which you conduct research Be sure to discuss at least the
following issues a) what model(s) would you use to approach the research
process b) theory evaluation and c) data collection
c Now take the perspective of a relativist Address the same issues raised in part
b
A10 In recent years there has been considerable debate in the social and behavioral
sciences concerning two competing research paradigms--one based on a logical
empiricismrealist epistemology and the second based on a post-empiricist
epistemology These paradigms vary with respect to their underlying aims
(goals) standards for judging explanations and ontology
a Describe the basic aims standards and ontology for each paradigm What
characteristics distinguish these two paradigms
b One current concern focuses on the appropriateness of a priori and post-hoc
explanations for theory testing Describe and defend your point-of-view
concerning which type of explanation is appropriate for research in
organizational studies
c A second current concern focuses on the appropriate treatment of the
independent variables that is an experimental approach (where the independent
variables are manipulated) and an observational approach (where the
independent variables are observed) Describe and defend your point-of-view
concerning which treatment of the independent variables is likely to produce the
more important contribution to organizational studies
A11 What rules of evidence are used by the positivist research paradigm to determine
whether a research finding is meaningful Choose another research
philosophyparadigm and compare and contrast it to the positivist rules of
evidence
A12 A major tenet of research is that research subjects should have limited if any
knowledge of the subject of the research The assumption is that subjects will
not act naturally if they are aware of the purpose of the research For this reason
researchers often engage in various types of deception For example
experimental and survey researchers will word instructions in such a way as to
hide the research goals and researchers who conduct participant observation
will avoid telling people they are researchers Discuss the ethical questions
raised with deception What guidelines would you give to a colleague who was
conducting research that involved deception
B) Causation
1) Explain the phrase ldquocorrelation does not equal causationrdquo Why is the distinction so
important What conditions must be met to establish causation Can they ever be
completely satisfied
12) Why is a posttest only design without random assignment to treatment conditions
uninterpretable from a causal standpoint
B1 Choose a model from the Organizational Behavior literature that has causal
orderings between variables and has been tested in a field setting Compare the
following data analytic methods for testing hypotheses about causality between
variable sets (eg dependent independent intervening moderating exogenous
endogenous)
a) path analysis using hierarchical regression
b) maximum likelihood estimates of structural equations models (perhaps through
LISREL)
Your answer should address
1 The parameters the procedures estimate and how they are estimated
2 How the validity of the models are judged
3 Appropriate inferences of causality and conditions necessary to make such
inferences
4 The statistical assumptions underlying each technique and the consequences of
violating assumptions
B2 Describe the critical-realist perspective of Cook and Campbell (1979) Compare and
contrast this perspective on causality with that of Poppers falsificationism
B3 According to Cook and Campbell (1979) causal relationships in the social sciences
can be probabilistic and still meet the assumption of causality that asserts that a
cause must always produce an effect Describe the logic they invoke to justify this
position
B4 Identify James Mulaik amp Bretts (1982) conditions for establishing causal
inference Discuss what they mean and why they are important to causal inference
B5 What are the three conditions necessary to establish causality Can these conditions
ever be fully met Why or why not
B6 Assume you are interested in conducting a study that allows you to legitimately
make some causal inferences concerning relationships among a set of constructs
What sorts of things can you as the researcher do to bolster your ability to make
such causal inferences In answering this question be sure to pay attention to issues
pertaining to both study design and data analysis
B7 Some researchers (and editorsreviewers) are very critical about the ease with which
others use causal language in interpreting their analyses What are the concerns
behind this criticism and what are the methodological and statistical conditions that
give rise to these concerns Under what conditions can researcher make reasonable
valid causal interpretations of their findings Can a researcher ever be completely
confident making such causal statements Be sure to defend your position in
answering these questions
C) Theory amp Research
C1 What are the elements of a theory What criteria did Bacharach (1989) use to
evaluate if a theory is good
IC
C2 The Academy of Management Journal in its Information for Contributors
states All articles published in the Journal must make a strong theoretical
contribution Because this is one of our top publications we must have a clear
understanding of what constitutes a strong theory Describe the essential elements
of a good theory You can also describe practices that are not indicative of good
theory if that will help you articulate what is good theory
C3 Organizational researchers place a high premium on research that is guided by
theory This perspective is evident in journals such as AMJ and ASQ which will
often reject a manuscript that describes a sound empirical study but does not
provide a theoretical contribution Is there a role for atheoretical research in the
organizational sciences If so what is the role of atheoretical research and what
contribution does it make to knowledge in the organizational sciences
TH
C4 Define inductive and deductive methods for generating knowledge What are the
advantages and disadvantages of each Under what conditions is each
appropriate
C5 Daft (1985) in Why I Recommended That Your Manuscript Be Rejected and
What You Can Do About It said that poor theoretical development is the
primary reason he recommended manuscripts be rejected when reviewing for
AMJ and ASQ
Why is theory considered so important
Give an example of a good theory and explain the elements that make it a strong
theory (Focus on theory development not on the content of the specific theory)
C6 You have undoubtedly heard the criticism of certain published articles in our
field being atheoretical Spoken as a criticism it suggests that research articles
should have theory Should every empirical article have theory Why is theory
important What are the hallmarks of good theory
2 RESEARCH DESIGN
A) Research Design Terms
5) Define internal and external validity Which is more important and why (It is not okay to
say they are equally important)
A1 Define (and discuss important features or issues concerning) the following
constructs of research design (Define any five terms)
1 Internal validity 6 Quasi-experimental
design
2 Stratified Sampling 7 Random Assignment
3 Solomon Four-group
design 8 Differential mortality
4 Factorial design 9 Demand
characteristic
5 External validity 10 Regression to the
mean
B) Level of Analysis
B1 IO psychologists have traditionally categorized themselves as being more micro or
macro in orientation usually falling toward the micro end Recent concern for what
has been termed the levels of analysis or cross-level approach has added a third
category - meso What is the meso level Is this just academic hairsplitting or re-
naming or is there a fundamental difference in this research strategy in contrast to
micro or macro Provide an example from some research domain of interest to you
that illustrates your conclusion of no real difference or important difference
C) Cross-Sectional vs Longitudinal Design
13) What are the benefits of a longitudinal design over a cross-sectional design in a non
experimental (correlational) study What are the disadvantages Why donrsquot we see
more longitudinal research
C1 The use of cross-sectional research designs continues despite many calls for
replacing them with longitudinal designs (a) What are the main strengths of
cross-sectional designs (b) What weaknesses do they have that longitudinal
designs supposedly counter (c) What are the implications of cross-sectional
designs for theory development (Consider internal and external validity)
C2 A good number of research efforts on the micro (OBHR) side rely on cross-
sectional designs in which surveys are used to collect both IVs and DVs from the
same respondent What are the various problems associated with such a design
What changes could be made to this design to alleviate andor eliminate these
problems What are the downsides of the new design (add in conveniencenon
probability samples)
C3 What are some of the major strengths of a longitudinal design Why dont we see
more of them
C4 Assume that you are analyzing a large sample of longitudinal survey data TH
Identify two characteristics of your data that would make ordinary least squares
regression (OLS) inappropriate for conducting analyses For each of these
characteristics describe an alternative analysis that is superior to OLS
D) Qualitative vs Quantitative Designs
D1 Compare and contrast the objectives strengths and weaknesses of
qualitativeobservational methods (eg ethnography) versus quantitative methods
(eg survey) in conducting empirical research on macro organizational issues Be
sure to consider issues of reliability generalizability validity ethics and
practicality in your answer Describe situations where one method or the other
may be most appropriate
IC
D2 In recent years a number of individuals have taken the position that qualitative
research is superior to quantitative research a Compared with quantitative
research what are the principal strengths of qualitative research b Compared
with quantitative research what are the principal weaknesses of qualitative
research
E) Observation vs Experiment
E1 Compare and contrast the objectives strengths and weaknesses of observational
methods (eg ethnographic methodology) and experimental methods Be sure to
consider issues of precision generalizability and realism in your answer Consider
also situations where one methodology or the other might be most appropriate
F) Laboratory vs Field Research
F1 Of the various research approaches available to organizational researchers
laboratory experiments are held up as an ideal because of their potential for high
internal validity On the other hand field research including participant observation
and field experiments have high potential for external validity Discuss specifically
the strengths and weaknesses of laboratory versus field experiments How would
positivist researchers think differently about these tradeoffs than would
phenomenologists
F2 In conducting an experiment in the laboratory or designing survey research there are
certain unique opportunities and limitations of each research strategy A) Describe a
hypothesized relationship between two constructs an independent and a dependent
variable in a substantive area of your choice (eg Strategy OB HRM
Organizational Theory) provide a verbal mathematical and graphical statement of
that hypothesis B) Briefly discuss how you would examine this hypothesized
relationship in a laboratory using experimental techniques versus a field survey using
correlation techniques C) Discuss what may be considered typical strengths and
weaknesses of each strategy regarding issues of precision and control in the
manipulation or measurement of the variables of interest realism of the context for
the participants and generalizability of the findings to other elements of a chosen
population D) Finally discuss advantages if any of using laboratory and field
survey methods in tandem
G) Experimental Design
2) A colleague suggests to you that only true experiments can provide useful results in
science Why might she say this What would you offer as a defense for the role of quasi-
experimental and non experimental designs in the context of the social science In
answering this question make sure you identify the defining characteristics of each design
type
9) Why and when should we be concerned about non response in research What are the
things we can do to try and decrease non response (or increase response rates)
11) Why might a researcher choose to utilize an experimental design that incorporates pretest
measure on the DV
G1 Experimental designs oftentimes come under attack due to perceived limitations in
external validity (a) Relative to other design types what strengths and weaknesses
do they offer (b) What experimental design structure is the strongest Why (c)
What is the relevance of research design for results and theory development
G2 Meta-analysts often investigate whether the quality of research design (eg
randomized experiments vs non-randomized designs) influences average effect
size In their meta-meta analysis of psychological educational and behavioral
treatments Lipsey and Wilson (1993) found that In a given treatment area poor
design or low methodological quality may result in a treatment estimate quite
discrepant from what a better quality design would yield but it is almost as likely
to be an underestimate as an overestimate (p1193) A few methodologists (eg
Shadish) have attempted to identify factors that may explain the relative magnitude
of effect sizes from randomized and nonrandomized experiments Please review
these findings and add your tentative model of the conditions under which random
experiments will produce larger smaller or equal effect sizes relative to
nonrandom designs Discuss possible implications for research design in the
context of real-world interventions
G3 Analysis of covariance and randomized blocks designs are sometimes referred to as
noise-blocking designs Explain what this means and give an example of (a) a
randomized blocks experiment and (b) an analysis of covariance experiment Keep
your examples simple Describe how such designs are noise-blocking when used
with randomized assignment of subjects to experimental condition and contrast
that with the role such designs serve in quasi-experimental designs
G4 Team performance in Bafko Industries varies considerably across teams and from
month to month The senior VP in charge of team development thought that a team
training program could improve the performance of these teams A consultant
convinced him that his firms training program which lasted only one week and
cost only $25000 per team) could raise the performance of Bafkos teams The VP
however wanted to experimentally test the efficacy of this training program before
he adopted it widely throughout the firm So the consultant suggested the following
experimental test
There were 48 teams in Bafko that showed significant variation from month to
month in their level of performance The consultant chose the 24 worst performing
teams based on last months data and assigned them to the training group After
all he argued these were the ones who most needed it The other teams were
assigned to the control group The training group received the training program
(lasting one week) at the beginning of the next month while the control group
teams did their normal routine Performance scores were gathered at the end of the
month The results showed that the training group teams had a significantly larger
rise (ie statistically significant) in their performance than did the control group
teams (who as a group did not improve at all) The consultant proudly displayed
these results and argued that they convincingly demonstrated the efficacy of his
program
How would you advise the VP Specifically what is the validity of the consultants
conclusions If you think he might be mistaken what specific threats to internal
validity are particularly plausible
G5 Consider the following design
N O Xa O
N O Xb O
N O Xc O
N O O where
Xa Xb and Xc represent different levels of a training program that varied in its
length across three different work groups In group a the training time was 40
hours in group b it was 30 hours and in state c it was 20 hours The training was
designed to instill customer service values in the team members O represents a
measure of customer service attitudes measured with a 20-item Likert scale This
measure was administered one week before the training program and 3 months
later The researcher hypothesized that the training program would improve
customer service attitudes and that longer training would have stronger effects
The design is a non-equivalent groups design because people were not randomly
assigned to groups even though groups were randomly assigned to treatment
condition Each group has a sample size of 36 members The reliability of the
customer service attitude scale was 78 at the pretest and 80 at the posttest The
pretest means were as follows
Group A 26
Group B 23
Group C 27
Control Group 25
a Construct a regression model that will test the researchers hypothesis Be
explicit here describing each variable in the model and what regression effect(s)
you would expect to find if the hypothesis were correct (Hint everything you need
to know is in Trochims chapter 11 and what we discussed in class) (10 points)
b Describe any serious threats to internal validity (10 points)
c Discuss how you might amend this design to improve its internal validity(10
points)
G6 Often in organizational research the researcher is faced with having only one group
on which to experiment and thus cannot use a control group when conducting
experiments This occurs for example in taxation experiments when you cannot
selectively apply new tax laws to different groups or when you wish to test the
efficacy of an incentive plan that must be applied to all members of a company In
such situations the researcher must be creative in assembling a quasi-experimental
design that has high validity (and usually the challenge concerns internal validity)
Consider the following scenario
A manager of a retail store wants to test the efficacy of an incentive program in
changing the selling behaviors of her retail sales clerks Specifically she wants to
test a behavioral reinforcement program in which sales peoples behavior is
recorded on in-store video cameras The tapes are analyzed each night and the
experimenter tabulates the frequency of various behaviors (eg offering assistance
to customers restocking items straightening up displays suggesting accessory
items to accompany the items that a customer is purchasing) The manager then
rewards the clerks with a monetary bonus based on the frequency of desired
behaviors She would like to conduct a valid experiment to see what effect such an
incentive program has on employee behavior but because of concerns about
employee morale she cannot assign clerks to treatment and control groups Instead
she has to apply the experimental treatment to everyone in the store She learned in
her research methods class (which the company requires all its managers to take)
that a single group experimental design typically has very low internal validity
Your job as a consultant is to help her design an experiment given her constraints
that would produce interpretable (ie internally valid) results Describe the details
of the design you would recommend using the notation in Trochim (2001) If the
design you come up with has a specific name use it As part of describing your
design discuss how the data would be analyzed and what particular effect you
would look for
G7 Why are experimental research designs held in such high regard
G8 Compare and contrast experimental quasi-experimental and correlational research
designs What characteristics separate these three designs What are their
advantages and disadvantages especially in comparison to one another
G9 What is the difference between a within-subjects experimental design and a
between-subjects experimental design When might a within-subjects design be
appropriate When might it be inappropriate
G10 Describe the difference between a basic within subjects and between subjects
experimental design What are the advantages and disadvantages of each
especially in comparison to one another Give an example from your area of
research in which each would be appropriate
G11 What are the major threats to the internal validity of a pretest - post test
nonequivalent control group design How can this design be improved with regard
to increasing a researchers ability to make causal inferences
G12 A production manager is interested in testing the hypotheses that participation in
quality circle programs will result in increased productivity and reduced
absenteeism A questionnaire is administered to a group of 92 employees
concerning their attitudes toward such programs and 46 with the most favorable
attitudes who are willing to participate are selected for the treatment group The
remaining 46 are the control group Measures of performance (unitsmonth for the
group) and absenteeism (lost daysmonth for the group) are kept over a three month
period during which the treatment group has weekly quality circle meetings The
results are as follows
Month 1 Month 2 Month 3 Month 1 Month 2 Month 3
Performance Absenteeism
Treatment 100 115 121 6 9 4
Control 110 108 113 6 8 5
The manager calculates t tests between month 1 and 3 The only significant
difference is performance for the treatment group so the manager concludes that
quality circles raise productivity but do not have an effect on absenteeism What
are the primary threats to internal and external validity in this study What are
possible alternative explanations for the differences (or lack of differences)
between the two groups What additional information might help explain these
results
G13 One stream of current strategy research contains event studies In these studies
investigators basically correlate the reaction of a financial market to the presence
andor absence of the occurrence of some event at a firm (eg the resignation of a
CEO) In a different approach to such a study suppose that one investigator (Jean)
conducts a natural field experiment on the effects of competitor mergers on a
firms environmental scanning activity Through previous arrangement Jean has
been working with 5 medium-sized computer hardware and 5 medium- sized
software firms on the west coast Shes been collecting a paper trail of internal
memos reports and phone calls that might measure environmental scanning
activity Shes been finding that the firms in both industries do about the same
amount of scanning (no significant differences) However in the midst of her data
collection Norton announces a merger with Symantec (software) A year later
Jean compares the amount of post-merger environmental scanning in the software
industry with that in hardware industry Just as Jean had hypothesized a t-test
shows a greater amount of post-merger scanning among the software firms She
concludes that her hypothesis was supported mergers of competitors cause an
increase in scanning
Critique the study described above in terms of its design flaws Identify the design
Jean used Briefly allude to problems the study has with external validity but
concentrate on the Cook and Campbell threats to internal validity Provide a
rationale for why each threat is or isnt operating in the study Link each of the
relevant threats to the specific constructs being studied (mergers and environmental
scanning) Finally do a summary evaluation -- what can be learned from this
study
H) Quasi-Experimental Design
H1 The University of Mississippi observed that the graduation rate of students with poor
grades during their freshman year was much lower than those with better grades
Wanting to improve the chances of these low performing students they tested the
effects of a new rule for freshmen The rule stated the following At the end of their
first semester all students with a GPA between 200 and 225 must register for
EDUC 1003 during their second semester Students with a GPA lower than 200
were put on academic probation EDUC 1003 consisted of a course whose objective
was to help students develop good study skills The theory was that poor study skills
were a significant cause of poor academic performance and that study skills could
be learned
They wanted to evaluate the effectiveness of this intervention so they collected data
on the GPAs of students beginning with their first semester and continuing through
to their third semester At that point they wanted to analyze the data to determine
whether the new rule was making a significant difference in the students academic
performance
What is the best way to analyze these data to reach an interpretable conclusion
Describe your approach and then discuss the major threats to validity that it has
Their sample size of students was as follows
Total N= 3454 (these are students who completed all 3 semesters)
Number of students with first semester grades between 200 and 225 (and thus took
EDUC 1003) was 956
H2 A nationwide furniture company wants to determine if a diversity training
program will improve individual sales performance on the floors of its urban retail
outlets A group of 45 salespeople in one city were given two weeks of training
Measures of individual sales performance were taken once two months prior to the
program and once two months after Forty-five salespeople (who did not receive the
training) in a similar city had the same measures taken at approximately the same
points in time The training group increased their average weekly sales from $14000
to $16500 while the non-training group improved theirs from $13000 to $14500
The change for the training group is statistically significant the change for the non-
training group is not
How would the interpretation of these results in this quasi-experimental design
differ from a true experimental design What are the threats to internal validity in
the above study and how might they be operating (be specific) What additional
information and analyses would be useful in controlling for these threats
H3 An accounting firm is interested in determining if a re-training program will reduce
errors made by its audit teams A group of 45 auditors in the home office location
are given two weeks of re-training Measures of the frequency of detectable errors
are taken once two months prior to the program and once two months after Forty-
five auditors in similar office at a branch location have similar measures taken at
approximately the same points in time The training group reduced their average
number of errors per audit from 8 to 3 while the non-training group reduced theirs
from 11 to 9 The change for the training group is statistically significant the change
for the non-training group is not
How would the interpretation of these results in this quasi-experimental design
differ from a true experimental design What are the threats to internal validity in
the above study and how might they be operating (be specific) What additional
information and analyses would be useful in controlling for these threats
H4 Describe the main classes of threats to validity that are found in quasi-experimental
research designs
H5 Dr Delta an organizational development consultant was hired by a firm that has
600 pizza parlors nationwide to assist in implementing organizational changes that
he hopes will result in higher levels of job involvement At the outset of the study
subjects had jobs with very low levels of enrichment and were paid on an hourly
basis He designed an experiment in which stores were randomly assigned to one of
three treatment conditions Condition 1 subjects experienced job enrichment (JE)
and a change to performance-based pay (PBP) Condition 2 subjects experienced
only JE and Condition 3 subjects experienced only PBP The parlors were
sufficiently far apart from one another and communication among the parlors so
poor that subjects in any parlor were totally unaware of changes made in other
parlors At the end of 18 months he measured the job involvement levels of workers
and then tested for differences between the three conditions using a standard one-
way analysis of variance In view of Dr Deltas design answer the following
questions
How sound is Dr Deltas design Comment on the weaknesses of the design
I) Interrupted Time Series Design
I1 What threats to internal validity are and are not ruled out by an interrupted time series
design that includes the introduction of a treatment and its removal at a subsequent
time period List and explain In the process be certain that you provide a diagram
that illustrates such a design
J) Validity Some Questions are about the validity of a measure others about experimental validity)
10) Identify four threats to internal validity and briefly describe what they mean
J1 It was some time ago that the tripartite view of validity was abandoned in favor of a
unitarian view in which different evidentiary bases for validity might be put forward
Binning amp Barrett (1989) represent an attempt to place multiple evidentiary bases into a
single framework Cook amp Campbell (1979) describe four aspects of validity but they
arent really meant to represent evidentiary bases Adding to the confusion is the fact
that while Binning amp Barrett and Cook amp Campbell use some of the same terms these
two pairs of authors clearly mean different things by these terms and intend for them to
be used in different ways Your task is to 1) Describe the evidentiary bases discussed
by Binning amp Barrett 2) Describe the aspects of validity described by Cook amp
Campbell 3) Describe the similarities and differences between the two lists including
the different purposes served by the two lists and 4) Present a single framework that
incorporates both This last task is the most important of the four
J2 What are the types of validity How would each affect an empirical study IC
J3 Define both internal and external validity Which is more important (it is not okay to
say that they are equally important) Defend your reasoning
J4 Why might someone argue that the construct validity of a measure can never really be
established
J5 Describe each of the following forms of validity content convergent discriminant
criterion-related and construct How is each assessed How do they related to each
other Which is most important (Make sure you defend your answer)
J6 Define and explain 6 of the 8 types of validity listed below and describe the type(s) of
information each provides Choose one specific type of study as an example (eg
cross-sectional study experiment quasi-experiment simulation ethnography etc) and
compare and contrast the usefulness and importance of each type of validity for that
type of study
-- Concurrent validity
-- Construct validity
-- Content validity
-- Convergent validity
-- Discriminant validity
-- Statistical conclusion validity
-- Internal validity
-- External validity
J7 Designing empirical research has been called making a series of trade-offs
Unfortunately decisions that are made to increase one desired quality (like internal
validity) can also decrease another desired quality (like external validity) For each of
the issues below discuss the concerns involved (ie the trade-off) and identify the
qualities that are being increased or decreased
a laboratory vs field study
b using a 5-item measure vs a 1-item measure
c using a student sample vs a sample of full-time employees
d using a sample of employees from one company of 5000 vs 500 employees from
each of 10 companies
e collecting your data using one method vs collecting your data using multiple
methods
J8 There are four major types of validity in social science internal validity external
validity construct validity and statistical conclusion validity Please address the
following three issues concerning validity
a What is the meaning of the four major forms of validity (ie internal and external
validity construct validity statistical conclusion validity)
b Are there trade-offs that can or must be made among the four types of validity
d Describe how the concept of validity varies across the research traditions of
experimental vs observational research
IC
J9 The quality of research is often assessed by examining validity issues As you are
aware there are numerous typesforms of validity (eg internal and external validity
construct validity statistical conclusion validity) These types of validity address
different aspects of the research process For this question please address the following
issues
a What is the meaning of the four major forms of validity (ie internal and external
validity construct validity statistical conclusion validity)
b Should there be a priority among these forms of validity If yes why If no why not
c Does the concept of validity vary across research traditions (ie experimental vs
observational research) If yes why If no why not
J10 External validity has received considerable attention in the social and behavioral
sciences Some researchers argue we are too concerned with the external validity of our
findings while other researchers argue that we are too unconcerned with external
validity Several points of view have been developed to explain what is external
validity When answering this question please be sure to address at least the following
issues
a Compare and contrast alternative conceptualizations of external validity
b Some researchers have argued that the role of external validity is invariant across
research traditions (ie experimental vs observational research) Defend the
perspective that the role external validity is invariant across these two research
traditions In addition present the weaknesses of this perspective
J11 In designing a research study researchers must consider trade-offs between internal and
external validity Explain what is meant by internal validity and external validity What
is the nature of these trade-offs How would you evaluatedetermine which is more
important internal or external validity for a particular study Why is this such an
important issue in organizational studies
J12 A researcher conducted a quasi-experiment to test the effects of participative decision
making (PDM) on job attitudes of employees Employees from different departments in
a large organization were assigned to either a treatment group (PDM implemented) or a
control group (no PDM) Random assignment was not possible because of work
schedules coordination of tasks etc Thus the design can be considered an untreated
control group design with pretest and posttest and is represented as follows (where
O=observation X = treatment)
________________
O1 X O2
-------------------------
O1 O2
_________________
The results of the experiment are presented in the graph below [no graph provided]
The dependent variable is job satisfaction and is measured on a 100 point scale (with
100 being extremely satisfied) How amenable are these results to causal interpretation
What is (are) the major threat(s) to internal validity B if any B for this type of design
given these results What steps can be taken to assess the extent of this (these)
threat(s)
K) Data Collection Methods
14) Describe the various methods of data collection (eg survey interview observation etc)
available to a social scientist What are the advantages and disadvantages of each relative to
each other
K1 Within micro organizational research much criticism has been raised concerning
the reliance on self-report survey data What potential problems does self-report
survey research raise How big of a problem do you think this is
K2 There are a number of methods for collecting data (eg survey interview archival
etc) that are available to a social scientistorganizational researcher Discuss each in
terms of their strengths and weaknesses both on their own and in comparison to one
another
K3 Pick an important construct in your favorite area of management research for which
there is some controversy about how it should be measured or operationalized (eg
environmental munificence or growth need strength) Give the prevailing verbal
definition of the construct and analyze the measurement controversy from two
broad angles First discuss how the controversy may or may not stem from claims
about how one measure is better or worse than another because it (or the other) is an
(a) archival record (b) direct observation (c) social report or (d) self-report That is
what are the relative strengths and weaknesses of each of these types of
measurement for the construct youre discussing Second discuss the construct
validity of the most commonly used measure(s) of this construct To answer this
second part you need to discuss just what construct validity is and how it can or
cannot be demonstrated In the situation you describe what could be done to
demonstrate or improve the construct validity of existing measures
K4 Interviewing in some form has been the workhorse for data collection in a variety
of research traditions positivistquantitative ethnographic feministpost-modernist
and increasingly historical research While each tradition elicits information from
respondents the goals and processes involved in interviewing vary considerably
across research traditions Discuss the purposes of the interview the relationship
between data and theory the roles assumed by the interviewer and the respondent
and the relevant criteria for assessing the validity and reliability of the information
obtained In addition compare and contrast the use of the interview as a data
collection method in the positivistquantitative tradition with its use in one of the
alternative traditions
L) Common Method Variance
L1 Many of us have had concerns about the reviews of our survey research which
suggest that data analyses of surveys are biased because of common method
variance effects of individual differences such as negative mood negative
affectivity and social desirability and the reliability and validity of the constructs
we are attempting to measure Define how these problems affect a research issue in
organizational behavior and the steps that might be taken to minimize such potential
criticisms of papers based on analyses of self-reported data through survey
instruments
L2 In a series of papers by Spector (1994) Schmitt (1994) and Howard (1994)
published in the Journal of Organizational Behavior arguments were provided for
and against the use of self-report questionnaire measures One of the issues
discussed that could limit conclusions drawn from relationships observed using self-
report measures was method variance What is meant by method variance what are
its sources and what impact is it expected to have on research findings
M) Sampling
M1 The manufacturing census samples all plants of 250 employees or more For
plants of 5-249 employees it takes a size proportional sample Plants of 1-4
employees are not sampled What challenges does this sampling method provide
to researchers What could you do to account for these problems if you were
TH
studying organizational (not plant) growth
M2 New York State has approximately 250000 employees in over 70 state agencies
commissions and boards ranging in size from approximately 50 to over 5000
employees Assume that you wanted to draw a representative sample of 1000
employees Describe two ways that you could draw such a sample and briefly
describe the advantages and disadvantages of each of these sampling approaches
IC
M3 The director of a national non-profit agency with approximately 10000
employees located primarily in regional offices in each of the 50 states the
United States has approached you and asked you to develop a study
(organizational survey) of organizational culture within the agency The agency
is about to embark on a variety of change initiatives including developing team
structures and the study is meant to examine various elements of organizational
culture that are potential barriers to change The director has indicated that he
would like to have the data analyzed at both the individual and office level of
analysis Because of funding limitations the agency will only be able to send the
survey to 1000 employees The director has indicated that there are three ways
of sorting employees all employees listed alphabetically all employees listed
alphabetically by state and all employees listed alphabetically by region (there
are between five and ten regions per state) Given these three ways of sorting
employees describe at least three different sampling approaches and the
advantages and disadvantages of each
M4 In your role as Teacher of Organizational Studies you are asked to prepare a
tutorial for beginning doctoral students on sampling design Assume that this
tutorial is part of a basic class in research design and that students in this class
have had a basic statistics course up to and including multiple regression Your
tutorial should focus on briefly defining and explaining the differences between
probability and non-probability samples You should make sure to present and
describe several types of probability samples (eg random systematic
stratified etc) and non-probability samples (eg convenience snow-ball quota
etc) and discuss general principles for when to use a probability vs a non-
probability sampling design For each sampling design you should also provide
at least one clear example of a situation where this type of sampling design is
appropriate
N) Cross-Cultural Research
N1 Discuss the problems in conducting cross-culturalnational comparison in terms
of (1) conceptualization and (2) research design and data collection
Define the three levels of measurement invariance How would the problems that
you have identified in part (a) affect measurement invariance How would you
examine measurement invariance by confirmatory factor analysis
TH
N2 Explain why using national boundaries as independent variable in cross-cultural
studies may not be appropriate in terms of theory and research methods What
alternative ways would you recommend
IC
O) General
O1 In your readings research has been described as choices among conflicting goals
(desiderata) For instance when choosing among research strategies a researcher
must choose among the desiderata of precision realism and generalizability The
trade-offs among desiderata occur for all aspects of research that is for the selection
of theories the treatment of independent variables research strategies the selection
of the problem to study rules of evidence for determining the meaningfulness of a
research finding and even the frameworks that describe the research process
Discuss what you see as the major trade-offs for each of the following aspects of
research That is discuss what you see as the major strengths and weaknesses
(advantages and disadvantages) of each aspect
a The trade-offs between internal and external validity
b The manipulation of the independent variable vs the observation of the
independent variable
c Basic vs applied research
3 DESIGNING A RESEARCH STUDY
A) General (Research Design)
3) Why is control so important in research design What are the different ways it can be
achieved (give a brief description of each control method) What are advantages and
disadvantages of each
A1 It has become almost a truism to note that the choice of methods influences theory
and questions data and conclusions (the causal direction might also be reversed)
Briefly discuss how the methods used have influenced research in any two of the
following areas leadership power and politics organization culture organization
justice Compare and contrast as possible Suggest some potentially fruitful
methodological directions for future work in these same topical areas and dont be
shy about reflecting on broader issues of how the field of organizational behavior
constructs its realities Lastly tie your discussion and reflections back to your own
future as a researcher what lessons or guidance do you derive from your
understanding of these issues
A2 Characterize as fully as possible what you see to be the methodological approach or
approaches in strategic management research Is there a dominant method or a wide
variety Discuss the reasons for the situation What are the advantages benefits etc
of the approach(es) in use What assumptions (ontological epistemological
ideological) do they embody Are current efforts ideal or at least adequate Are
there other approaches that could be useful If so how might researchers be
encouraged to use these as well If you see no advantage to more variety in
methodological approach support that point of view
A3 Describe a research question or area of interest to you and why you think it is not
only of interest but significance Using your understanding of research methodology
describe two ways of pursing the question that are as divergent on as many
dimensions as you can imagine Describe the advantages and disadvantages of each
approach How strong a link or fit is there between a research question and a
method
A4 In his 1957 article entitled The two disciplines of scientific psychology Cronbach
discussed the assumptions goals and methods used in experimental methods and
correlational methods in psychology
a According to Cronbach what is the main difference between the two disciplines
b Discuss the strength and weaknesses of each discipline
c What if anything could be done to improve the situation
B) Designing a Research Study
B1 Cook and Campbell describe the experiment as the research design with the
greatest methodological rigor However given the constraints present in most
organizations I-O Psychologists cannot often conduct experiments in applied
settings and must settle for techniques with less control than experiments
Describe a study to investigate the relationship between participation in a
supervisor training program and work performance which could realistically be
conducted in an organization If an experiment is not possible describe how you
would go about maximizing your ability to draw valid conclusions from your
design
B2 The XYZ Co has recently developed a sexual harassment web-based training
program The developers claim the program will cut training time and costs and
will be as effective or more effective than classroom-based sessions They
believe that this will be due to the increased availability of the program and the
ability for participants to review program material on demand Before the XYZ
Co developers launch this product they want you to determine if their claims
have merit Explain how you would design a study for this purpose
B3 Research suggests that demographic diversity improves group creativity but
reduces group efficiency Some argue that demographic diversity is just a proxy
for value and experience diversity and that demographic diversity on its own is
meaningless Design a test to settle this argument
TH
B4 E-mail has become a common form of communication in organizations and is
used for both formal and informal communication Because it has become so
IC
popular some people complain that the frequent use of e-mail leads to
miscommunication because they receive communications in e-mail that should
be accomplished through face-to-face or telephone conversations where there is
an opportunity for interaction You are interested in looking at this
phenomenon You are most interested in describing how e-mail is used for both
formal and informal communication and in examining the effect of the e-mail
use on organizational communication effectiveness Design empirical research
to address those issues
Describe your study in detail thoroughly explaining the research design
sampling plan data collection procedures ethical issues and proposed data
analysis for your research design Be sure to discuss the internal and external
validity of your research Which validity threats are ruled out and which
remain
REMEMBER Be thorough Your research design should demonstrate that you
are a competent researcher who is knowledgeable about the proposed research
methodology or methodologies Therefore be sure that you carefully describe
and give technical explanations for each component of your research
B5 Choose a specific situation involving employee selection eg artists for an
advertising agency (a) What strategy would you use in selecting the selection
measures (b) How would you combine the measures eg which measures
would you combine in a compensatory manner and which is a noncompensatory
manner (c) How would you assume test fairness defining various measures of
the term (d) How would you make final selections (e) How would you
validate your procedure (f) What considerations would enter in if your
company were too small to provide validation data (g) What difference would
it make if you were developing a procedure for deciding whether trainees
should be promoted as opposed to making new hires Please note--emphasize
but do not limit yourself to statistical issues
B6 There is evidence in the marketing literature of a non-monotonic relationship
between the expectations that customers have for retail service and their
eventual level of satisfaction with that service That is as a customers
expectations for service increase so does their eventual service satisfaction --
up to a point After that point the greater the expectations the lower the
eventual satisfaction Develop a hypothesis that includes a moderator variable
that might account for this evidence Give some reasonable rationale for it State
your hypothesis verbally as an equation as a directed graph (circle amp arrow
diagram) and as an X-Y function chart Discuss how it would or would not be
possible or useful to test your hypothesis via a laboratory experiment In your
discussion cover how and why a researcher could (not) manipulate the
independent constructs involved (mode X) whether or not random assignment
to conditions (mode R) is possible (including how may conditions would be
necessary) which alternative constructs could or could not be controlled (mode
K) and which constructs should be measured (mode Y)
B7 Assume you are the chairperson of a committee that must evaluate
undergraduate programs at your university Your task as chairperson is to
devise an approach (a design a research strategy a set of measures) that will
allow you to evaluate undergraduate programs Make sure that your approach
can be used in the future and at other comparable universities When developing
your plan be sure to address at least the following issues
a the type of design you would select Compare and contrast the selected design
with another possible design
b the type of research strategy you would select Compare and contrast with
another possible strategies
c discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
B8 Assume you are an organizational research design expert assigned to the
Strategic Planning Department of a large multi-national manufacturing firm
The Department has developed a new PC-based software package called
STRATPACK The software (and a one-week training course to learn how to
use it) is intended to improve the long-range planning ability of middle and
upper-level managers
Your job as research design expert is to devise research (a design a research
strategy a set of measures) that will allow you to evaluate the effectiveness of
the STRATPACK program Describe a research design for evaluating the
program Make sure that your research approach can be used in the future and at
all sites in the company When developing your plan be sure to address at least
the following issues
a discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
b the type of design you would select (eg a design where you manipulate the
independent variable versus observe the independent variable) Compare and
contrast the selected design with another possible design
c how your design deals with the major forms of validity Be sure to examine at
least internal external and construct validity
B9 Assume you are a consultant hired to evaluate the effectiveness of an industrial
safety program undertaken by a large manufacturing organization The safety
program is a behavioral one that provides rewards such as monetary bonuses or
extra paid vacation days for safety behaviors in terms of accident-free days
weeks etc Your task is to devise an approach (a research strategy a design a
set of measures and a general analysis strategy) that will allow you to evaluate
the safety program Because of the potential for the influence of many
extraneous variables on any safety program it is difficult to design research a
single cross-sectional study than can evaluate the impact of a single safety
program How would you design a study to evaluate the impact of the safety
program When developing your plan be sure to address at least the following
issues
a the type of research strategy you would select Compare and contrast with
another possible strategies
b the type of design you would select Compare and contrast the selected design
with another possible design
c discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
B10 One of the most important areas of research is forecasting of human resources
needs based on strategic positions of organizations For example NY State must
carefully forecast its human resources needs as it proceeds with significant lay-
offs of state employees Future human resources needs are generally evaluated
by either statistical ie regression or simulation or clinical judgment i e
supervisors judgments methods
a Design a single study that addresses the empirical question of whether
statistical or judgmental methods are better for forecasting human resources
needs You may discuss a program of research but please be quite specific in
your description of the first study
b What are the critical methodological issues in doing this kind of research
c What are the critical applied (or practical) issues in doing this research
d Are the issues in b and c related
B11 In the past decade computinginformation technology has changed many
aspects of organizational life For example the technology can make increased
decentralization possible by improving communication between central offices
and field offices Computer networks and word processors can enhance group
empowerment by making it possible for team members to create and edit
written group products quickly even if the individuals are at different locations
Some have argued that computinginformation technology will foster the
paperless productive office nevertheless others argue that the technology only
increases paper and reduces office productivity You are applying to the
National Science Foundation for a grant to conduct research that examines the
impact of computing information technology on organizational decision
processes The NSF application procedure imposes five basic requirements that
your research design must fulfill in order to receive funding Note A very
significant factor affecting NSF grant decisions is a clear demonstration that the
researcher is knowledgeable about the research methodology used Write your
response to each of the following five grant requirements Be sure not only to
respond to the requirement but also to demonstrate your research
competence
1You must design a study that uses two different methods
(interviewobservation survey experiment or quasi-experiment) Describe your
two methods in detail and provide a rationale for the key elements (eg
sampling data collection proposed analysis) of your methods Be sure to
discuss and evaluate the internal and external validity of both methods
2 As part of your research design you must select a conceptual (latent) variable
central to your proposal (use centralization of decision making as your
variable) and describe how you will develop your own measure (You may not
simply use off the shelf instruments)
3 You must describe how you will test for the reliability of the measure
(centralization of decision making) you developed in step 2 The NSF insists
that you describe how you will evaluate both the temporal stability and the
internal consistency of your measure Be sure to discuss what temporal stability
and internal reliability mean and how they are related
4You must describe how you will assess the validity of the measure
(centralization of decision making) you developed in step 2
5 NSF requires a brief statement and defense of the philosophy of science
underlying your research Discuss your position and show how your research
design is consistent with your philosophy
B12 Many organizations in the United States economy have installed some form of
Empowered Teams as an alternative or supplement to traditional bureaucratic
structure Preliminary evidence of the effectiveness of empowered teams
however is mixed--some organizations have claimed success and others have
reported failures The evidence however is predominantly anecdotal--written
for trade magazines by the organizations themselves There are few rigorous
empirical studies assessing the effectiveness of empowered or self-managed
teams You are applying to the United States Department of Labor (USDOL) for
a grant to conduct research that examines the effectiveness of empowered
teams The application procedure of the USDOL imposes three requirements
that your research design must fulfill in order to receive funding Write your
response to each of the three grant requirements The importance of each section
is implied by the evaluation points allocated by the USDOL to each of the three
requirements given in parentheses
1 (50 points) Your study design for assessing Empowered Team effectiveness
must use two different methods (interview observation archival analysis
survey simulation experiment or quasi-experiment) Describe in detail and
thoroughly explain the sampling plan instrumentation data collection
procedures and proposed data analyses for both methods Be sure to discuss the
internal and external validity of both methods and how the two methods
complement one another
2 (30 points) As part of your research design you must select one conceptual
(latent) variable central to your proposal and describe how you will develop
your own operationalization of the measure (You may not simply use off the
shelf instruments) Use the concept of group morale to demonstrate your
operationalization methodology Be sure to explain very explicitly to the
USDOL how you will assess the validity and reliability of the group morale
measure you are developing
3 (20 points) The USDOL traditionally has funded research conducted only
within the general paradigm of logical positivism but now is more open to other
research paradigms as well Your grant proposal must provide a statement and
defense of the explicit philosophy of science underlying your research Describe
your philosophy of science and show how your research design is consistent
with your philosophy
REMEMBER Be thorough You not only must design effective research but
you also must demonstrate to the USDOL that you are a competent researcher
It is absolutely vital to the USDOL that the principal researcher is
knowledgeable about the proposed research methodologies Therefore be sure
that you always carefully describe and give technical explanations for each
component of your research design and explain all technical terms (eg
Cronbach alpha KR-20 Likert scale)
B13 Assume that you are working as part of a research team that is responding to a
RFP (Request for Proposals) from a funding agency for research on work
socialization and newcomer adjustment The RFP calls for rigorous field
research that tests the effectiveness of theory-based interventions aimed at
facilitating the adjustment of new organizational members to complex andor
stressful work conditions The major goal of your teams research is to test the
effectiveness of a self-regulation intervention which trains newcomers to
identify and use relevant social information and cues to regulate work behavior
Your group hypothesizes that self-regulation training will be more effective
than other common treatments or interventions (eg realistic job previews
institutionalized socialization tactics)
You have been included in the team because of your methodological expertise
Your role is to design a rigorous field experiment or quasi-experiment to test he
effectiveness of the self-regulation training program REMEMBER THE
MAJOR CRITERION FOR FUNDING IS THE RIGOR OF THE RESEARCH
DESIGN Design a field study to include in the grant proposal Your proposal
should contain the following two sections
1 Study Design Construct and describe in detail an experimental or quasi-
experimental design to test the effectiveness of your intervention Describe in
detail the experimental groups (including how they will be constructed) the
research setting the sampling plan for study participants the treatment
manipulation and the data collection procedures Also indicate any control or
nuisance variables that may be measured
After describing the procedures write a justification of the design What threats
to validity does it rule out or limit and what threats to validity remain
II Measurement Describe the steps you would take to achieve valid and
reliable measure of the latent (conceptual) variable worker adjustment Your
team feels that as part of the proposal you must develop an original
operationalization of adjustment (thus you cannot simply use existing off the
shelf measures) Indicate in adequate detail how you would operationalize the
measure and indicate how you would demonstrate reliability and validity
B14 In describing their notion of the collective mind Karl E Weick and Karlene H
Roberts note Our focus is at once on individuals and the collective since only
individuals can contribute to a collective mind but a collective mind is distinct
from an individual because it inheres in the pattern of interrelated activities
among many people (p 360) Collective mind is not indexed by within-group
similarity of attitudes ideas or activities A collective mind is one in which
many people or many groups integrate their different attitudes ideas and
activities heedfully As Weick and Roberts note People act heedfully when
they act more or less carefully critically consistently purposefully attentively
studiously vigilantly conscientiously pertinaciously (p 361)
The idea of the collective mind as heedful interrelating is developed in the
following excerpt When people make efforts to interrelate these efforts can
range from heedful to heedless The more heed reflected in a pattern of
interrelations the more developed the collective mind and the greater the
capability to comprehend unexpected events that evolve rapidly in unexpected
ways When we say that a collective mind comprehends unexpected events we
mean that heedful interrelating connects sufficient know-how to meet situational
demands For organizations concerned with reliability those developments
often consist of unexpected non-sequential interaction (p366)
An example of heedful interrelating occurs as a pilot lands herhis aircraft on the
deck of an aircraft carrier The pilot does not actually land She is recovered
A recovery is an interrelated set of activities among air traffic controllers
landing signal officers the control tower navigators deck hands the helmsman
driving the ship etc These activities can be interrelated more or less heedfully
depending on the care with which the different units contribute represent the
situation and subordinate their activities to the single purpose of successful
recovery (p 363)
You are to design a two-part study
Part I You are to design a measurement study which assesses heedful
interrelating (ie collective mind) with a quantitative measure in a replication
of an aircraft carrier flight deck or other situation of your choosing Describe
your research strategies including operationalization of the variable selection of
the sample subjects data collection data analysis and so on for the purpose of
developing a measure of heedful interrelating
Part II Using the measurement tool developed in Part I and any other tools as
needed describe how you would design a study which would compare heedful
interrelating across organizations Choose at least one macro-organizational
variable (eg technology environment) as your basis of comparison Here you
must describe how you would make your selection of organizations to be
compared your data collection procedure data analysis and so on
B15 Many organizations in the United States have installed cross-functional teams to
counteract the silo mentality of traditional bureaucratic structure Preliminary
evidence of the effectiveness of cross-functional teams however is mixed --
some organizations have claimed success and others have reported failures The
evidence moreover is predominantly anecdotal--written for trade magazines by
the organizations themselves Since there have been few rigorous empirical
field studies assessing the effectiveness of cross functional teams the National
Science Foundation has decided to fund research on the topic
Assume that you are submitting a research proposal to NSF for a grant to
research the effectiveness of cross-functional teams Describe in detail and
thoroughly explain the research design sampling plan data collection
procedures ethical issues and proposed data analysis for your research design
Be sure to discuss the internal and external validity of your research Which
validity threats are ruled out and which remain NSF also requires that you
provide a statement and defense of the explicit philosophy of science underlying
your research Describe your philosophy of science and discuss how your
research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but
you must also demonstrate to NSF that you are a competent researcher It is
absolutely vital to NSF that the principal researcher (you) is knowledgeable
about the proposed research methodologies Therefore be sure that you always
carefully describe and give technical explanations for each component of your
research design and explain all technical terms (eg Cronbach alpha KR-20
Likert scale)
B16 Assume that you are submitting a research proposal to the Department of
Commerce (DoC) for a grant to research the effectiveness of virtual work teams
A virtual work team is a leaderless collection of individuals who are
geographically separate from one another and share their expertise using
internet media such as a listserver or Lotus notes The DoC requires that the
researcher use both qualitative and quantitative methods to gather data Describe
in detail and thoroughly explain the research design sampling plan data
collection procedures ethical issues and proposed data analysis for your
research design Be sure to discuss the internal and external validity of your
research Which validity threats are ruled out and which remain The DoC also
requires that you provide a statement and defense of the explicit philosophy of
science underlying your research Describe your philosophy of science and
discuss how your research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but
you must also demonstrate to DoC that you are a competent researcher It is
absolutely vital to DoC that the principal investigator (you) is knowledgeable
about the proposed research methodologies Therefore be sure that you always
carefully describe and give technical explanations for each component of your
research

5 MEASUREMENT
A) Measurement Terms
A1 There are four levels of measurement rigor in management research Discuss each
one What properties do measurements at each level have (ie how much
information do the numbers from each level of measurement convey) How can the
numbers be changed (transformed) and still retain the properties of their
measurement level Pick one construct from a favorite research domain and give an
example of an operationalization of that construct at each of the four levels of
measurement rigor (provide arguments about why you think those examples reflect
each level) Lastly treat each examplelevel as a dependent variable in some
statistical analysis Given an example of a statistical technique appropriate for
analyzing data at that level of measurement rigor
A2 Define (and discuss important features or issues concerning) the following
constructs measurement (Define any six terms)
1 Construct validity 6 Item analysis
2 Likert scaling 7 Semantic differential
3 Cronbachs alpha 8 True score
4 Unobtrusive (trace) measurement 9 Generalizability theory
5 Interval scale 10 Criterion-related validity
11 Sociometric choice measures
B) Operationalization
B1 a) You are conducting a study which requires you to measure Hong Kong real
estate agents self-assessment of performance Since there is no existing
measurement available you have to develop the instrument by yourself
Describe how you would develop the measurement assuming that you have no
idea of how many dimension the construct has
b) Suppose you have developed an instrument consists of 20 questions
measuring 4 dimensions (5 items per dimension) from (a) You collected data
from another 300 real estate agents to validate your instrument Explain how
TH
you would use structural equations model (SEM) to examine the reliability and
validity of the instrument What are other concerns about reliability and validity
that are not addressed by this approach
B2 The research and business world have been fascinated with the concept of
organizational culture However operationalizing this construct has been a
difficult task Discuss the ways in which the construct has been operationalized
(eg technique static v dynamic sample selection generalizability) Critically
analyze each of these methodologies Then choose a methodology you would
use to examine organizational culture and defend your choice Describe how
you would study culture and what more would be known about culture as a
result of your study
B3 Suppose you are setting out to develop a new measure of a construct You want
this measure to be used in survey research and you want to establish its validity
and reliability Your goal is to have at the end of the process a measure that is
defensible and likely to be widely accepted by other researchers studying that
construct What steps would you take to conduct such a program of research
For each step explain the purpose of that step explain why that step is
important explain what methods and statistical procedures you would employ at
each step and explain what evidence you would hope to gather at each step
B4 Assume you are interested in constructing a new measure of (fill in with a
relevant variable from your field) Detail the major concerns that need to be
addressed and the steps that need to be taken in working toward validating this
new measure
B5 Assume that you recently read an article on workplace violence which you
found very interesting The authors argued that one of the predictors of
workplace violence was a construct called propensity to be violent and used a
one-item measure as follows How likely are you to become violent when
provoked You had serious doubts about the authors measure and decided to
develop your own
(a) How would you go about developing items to measure propensity to be
violent
(b) How would you determine whether the instrument was reliable
How would you determine whether the instrument was valid
B6 A concern in organizations is retirement of baby boomers within the next 5 -
10 years This concern is focused on the loss of older employees with skills
critical to the core business functions of organizations In order to continue to
have employees with those critical skills it seems necessary to retrain some
older workers However past practice in most organizations has been not to
retrain older workers for a variety of reasons mostly financial A researcher
working for the Human Resources Department of a large corporation - 13500
employees in 12 different plant locations - hypothesizes that the major reason
for not retraining older workers is ingrained in the culture of the corporation

each of them in various situations For each measure below indicate the types of
error and sources of error that are most likely to affect it Then indicate what

C11 Suppose you had conducted research on the relationship between organizational
commitment and rigidity of organizational structure in 200 firms Your measure
of rigidity was based on number of organizational authority levels and the degree
to which written organizational rules existed and defined role behaviors for
employees Thus an organization with a large number of organizational levels
and specific written policies defining appropriate role behaviors for employees
would score high on rigidity of organizational structure After analyzing your
data you find that there is a statistically significant negative correlation between
commitment and rigidity which is consistent with your hypothesis However the
reliabilities for your two measures are
(1) commitment = 23 (2) rigidity = 83
How should you interpret your results What could you do to fix this situation
Describe the specific steps (in order) you would follow to develop a more

and supports continuous learning Describe how you would measure organizational
climate in this case Specify (a) the level (ie individual group organization) at
which the construct exists (b) the level at which you would measure the construct
and (c) the procedures that you would use to establish that measurement is aligned
with theory (ie the construct validity of the measure)
E) General (Measurement)
E1 Studies in organizational behavior research often rely on single-item measures of
key constructs The use of single-item measures has long been criticized based
on the premise that single-item measures are unreliable However Wanous
(Wanous amp Hudy 2001 Wanous amp Reichers 1996 Wanous Reichers amp Hudy
1997) has recently argued that single-item measures can exhibit adequate
reliability Wanous based this conclusion on a procedure for estimating the
reliability of single-item measures using the classic formula for correction for
attenuation Subsequent studies have yielded mixed results regarding the
conclusions of Wanous (eg Loo amp Kells 1998 Nagy 2002) and the veracity
of the perspective advocated by Wanous remains in question Summarize and
assess the arguments for and against the use of single-item measures and
evaluate the procedure and evidence offered by Wanous regarding the reliability
of single-item measures Based on your assessment and evaluation develop
recommendations regarding the use of single-item measures in organizational
behavior research

E2 Ipsative measures have become prevalent in organizational behavior research
Ipsative measures ask respondents to answer questions relative to one another
such that the scores for all questions sum to the same constant for all respondents
Examples of ipsative measures include rankings Q-sorts and the allocation of a
fixed number of points (eg 100) across a set of response options Ipsative
measures may be contrasted with absolute measures which ask respondents to
answer questions independently from one another Absolute measures are
exemplified by rating scales using an interval or ratio numeric response format
The relative merits of ipsative and absolute measures have been debated for
decades (eg Cornwell amp Dunlap 1994 Hicks 1970 Johnson Wood amp
Blinkhorn 1988 Saville amp Wilson 1991 1992) yet the fundamental issues
underlying this debate have not been adequately addressed in organizational
behavior research For example measures of organizational culture and values
are often ipsative and some researchers advocate these measures over absolute
measures (eg Meglino amp Ravlin 1987 OReilly Chatman amp Caldwell 1991
Ravlin amp Meglino 1987 see also Rokeach amp Ball-Rokeach 1989) Review the
relative merits of absolute and ipsative measures Based on your review which
form of measurement is most appropriate and why Do your conclusions depend
on the construct being measured If so what types of constructs are best suited to
ipsative measures and what types are best suited to absolute measures Next
apply your conclusions to the measurement of culture and values in
organizations What specific arguments have been advanced in favor of ipsative
measures of culture and values How sound are these arguments Should ipsative
measures be used in the study of organizational culture and values If not how
can absolute measures of culture and values be developed that address the
concerns voiced by advocates of ipsative measures Provide a specific example
of the type of measure you would propose

facets of a concept Although such measures are prevalent and in some cases are

E5 Suppose Roberta Von Eisenbrick is a researcher interested in the consequences of
AFFECTIVE CONFLICT (AC) in decision-making teams She gets access to a
variety of outcomes assessment committees at each of 87 different schools in
the Dallas Independent School District and gains permission to tape-record two
of their meetings (one in February and one in March) Such committees have
been formed to develop quantitative ways to track pursuit of school goals and
provide accountability to local and state governments These are often divisive
teams with heated meetings because what gets assessed is what usually gets
rewarded After both of these meetings the committee members each
fill out a short questionnaire that contains 20 Likert-type items measuring how
much AC occurred (eg People in our group often get angry with each other)
The individual scores are summed across items then averaged across team
members to come up with a group-level AC score for each of the 87 2
meetings The same procedures are followed for a 5-item measure of Group
Cohesiveness (GC) which is predicted to be reduced by higher levels of AC
Roberta also listens to every tape and from her expert judgment she rates each
groups meetings on the same 20 items Those 20 ratings are summed for each of
the 87 2 meetings Now Roberta is interested in evaluating her measure She
wants it to have excellent psychometric properties including reliability and
construct validity

D1 Moderation and mediation provide different ways to model third variable effects
(a) Please define both of these terms (b) Sketch a conceptual model to show how
each relates to main effects (c) Using variables of your choice please write
hypotheses to reflect both (d) Explain how each is tested analytically
D2 Discuss moderators and mediators Provide an example of how (1) a moderating
variable influences the relationship between the independent and dependent
variable and how (2) a mediating variable influences the relationship between
the independent and dependent variable Describe how you would test for both
moderation and mediation using regression
D3 Many theories in organizational research predict that the effects of one variable
on another are moderated by a third variable Such moderator effects are
typically tested by entering the product of two variables as a predictor after
controlling for the two variables that constitute the product Several researchers
have pointed out that this product is often highly correlated with the squares of
the two constituent variables and have suggested that moderating effects may be
tested after controlling not only for the two constituent variables but also their
squares (eg Cortina 1993 Ganzach 1998 Lubinski amp Humphreys 1990
MacCallum amp Mar 1995) Discuss the strengths and weaknesses of this
approach as compared to methods that use only the product term and its
constituent variables Conclude with recommendations as to when and under
what conditions organizational researchers should test moderator effects with the
squares of the constituent variables in the equation

D4 Assume you are interested in studying relationships amongst three variables X
Y and Z Your first hypothesis posits Z as a mediator of the relationship between
X and Y Your second hypothesis posits Z as a moderator of the relationship
between X and Y Draw the figures depicting each of these hypothesized
relationships and describe (make sure to write regression equations) how you
would test each of these hypotheses
D5 The amount of time and effort that the average person pours into his or her job
has risen steadily over the last two decades such that the average person now is
working one more week per year than the average person in the mid 1970s This
steady increase has fueled research interest in the construct of Job Burnout (JB)
which is an emotional and physical exhaustion associated with ones work
Organizational Stress (OS) the perception of greater demands than available
resources in ones work environment is thought to be one of the chief
antecedents of JB However time spent under OS is thought to make its affects
on JB accumulate or worsen Work Role Withdrawal (WRW) the avoidance of
responsibilities or the deliberate reduction of inputs to ones job is believed to be
the chief consequence of JB
a Formally state these ideas as verbal hypotheses as equations and as a complex
directed graph (circle amp arrow diagram)
b Conceptually what is a mediator Define the term and identify the mediator in
your hypotheses in (a) What elements or steps in a study design (not statistics)
that would be helpful for detecting the mediating relationship that was proposed
c What is a moderator What are some of the other names for it within various
subdomains of management Further demonstrate your understanding of
moderator variables by picking which variable in (a) is the moderator Show the
moderating relationship in an X-Y (or multi-layered) chart Again what elements
or steps in a study design (not statistics) would be helpful for detecting the
moderating effect implied above

matter exam than those using the old book (p = 027) Both books are readily availabe their prices are almost identical and both are equally acceptable to the instructors What is your recommendation to the chair
F1 Attached is the beginning of an article Your task is to write the results section by

reader understand the results of the statistical tests you report and the nature of your
sample (Hint this can be presented in the form of a table)
2 describing and defending your choice of appropriate statistical tests of the
hypotheses and the steps that you would go through in carrying out these tests
3 making up and reporting results of these tests that are consistent with your
descriptive statistics and with any information in the rest of the article about the
results found (Hint this can be presented in the form of a table)

may want to note any relevant threats to validity here
Be sure to state any assumptions you make
F2 Assume that the Personnel Manager of a local firm Ms B dFlandres hired you to
analyze some data that her assistants had collected over the past several years The
data consist of (a) job performance ratings that were made in June of 1990 and (b)
scores on 25 predictor variables (eg measures of education job experience job
tenure job aptitude personality) that were measured when the individuals were hired
(between April 1987 and May 1988) She had data from only the 110 subjects (60
males and 50 females) who were hired during the period and were still employed by
the firm One objective of your analysis (analyses) is to determine how well the
performance criterion can be predicted by the predictors What strategy would you
use in analyzing the data Describeexplain (b) Is sample size an issue for your
analyses Explain If it is what will you do to deal with problems stemming from
sample size Assume that no additional data can be collected at this time (c) Some
preliminary analyses that you do reveal that five of the predictor variables correlate
(zero-order basis) about 75 with one another Will this influence the analyses that
you use Will it influence the validity of conclusions derived from your proposed
analyses (d) Ms dFlandres is interested in knowing if the predictor variables are
equally effective in predicting the job success of males and females What analysis
or analyses would you do to deal with this issue
F3 Assume that you have been provided with data on 12 conceptually distinct variables
that are moderately correlated with one another at the empirical level The data are
from students in four different college majors ie astronomy (A) biology (B)
criminology (C) and demography (D) The 12 measured variables fall into the
general categories of mental health (tension emotional withdrawal hallucinations
guilt feelings blunted affect and suspiciousness) and job satisfaction (work itself
supervision co-workers pay promotion prospects and working conditions) Your
task is to determine if the individuals in the four college majors differ from one
another on the 12 measured variables
(a) What statistical technique(s) would you use to test for group differences
Explain Be specific about the procedures(s) that you would use
(b) What statistical estimate would you use to estimate the extent to which the
groups differ from one another Be specific
F4 The following statistical table published in a recent issue of Work amp Occupations
was taken from an article discussing variables influencing resistance and citizenship
behaviors in the workplace Resistance behaviors include playing dumb withholding
effort work avoidance subverting particular managers and sabotage Citizenship
behaviors include cooperation engaging in peer training use of insider knowledge to
facilitate production commitment to organizational goals giving extra effort freely
Both measures are global constructs aggregated to the interval level and
standardized
The table reports the results of a series of ordinary least squares regression equations
with standardized coefficients Explain the meaning of the statistics presented What
do these statistics tell us generally about the relationship between resistance
behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows
Anomie Index -standardized interval level measure tapping multiple dimensions
The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)
F5 Researchers collected data from a sample of 350 companies on the following
variables
size (measured as number of employees)
Business Strategy (a nominal variable with 2 response options low-cost provider or
differentiator)
HR Strategy (a nominal variable with 2 response categories High commitment or
low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

procedures Your students already have had the basic course in bivariate statistics
(eg t-test F-test ANOVA correlation etc) and are beginning their study of
multivariate data analysis techniques Outline a tutorial for your graduate students
thoroughly describing and explaining one of the following multivariate statistical
analysis techniques Multiple regression factor analysis discriminant analysis
canonical analysis cluster analysis or MANOVA (Your tutorial can be conceptual
it need not present any mathematical formulas unless you wish to) In your tutorial
be sure to discuss (among other issues)
1 The type of output that results from applying the technique How to interpret
results from the technique
2 The assumptions underlying the technique and the consequences of failures in the
assumptions
(Note Your tutorial will be evaluated on your demonstrated competence with the
statistical method not on the pedagogy of the tutorial)
I) ANOVA
I1 ANOVA Assume that you have conducted a laboratory experiment in which there
were 3 levels of Factor A (a1 a2 a3) and two levels of Factor B (b1 b2) Assume also
that there were 20 subjects in each cell
(a) Prepare a standard analysis of variance (ANOVA) table that is appropriate for this
design Make certain that you specify all effects and the appropriate degrees of
freedom for each effect If you use any abbreviations in your table make certain that
you specify their meaning
(b) Assume that an initial ANOVA analysis found no evidence of an A X B
interaction What if anything would you do with the sum of squares for the
interaction effect
I2 A study examined the effects of gender and pre-training motivation on the transfer of
training in terms of improved performance for 123 new industrial managers The
training was on supervisory skills and the dependent variable was based on the
appraisal of the supervisors performance before the training and three months after
the training The performance appraisal data were collected for research purposes
only and resulted in a total transfer score from 1 to 25 with 1 being low Pre-training
motivation was based on a 12 item Likert scale with an alpha of 86 Two groups
were identified for the pre-training motivation variable - the bottom 13 (low) and the
top 13 (high) Table 1 contains the ANOVA results and Table 2 contains the cell
means
a What experimental design was used in this study
b What assumptions are made in the ANOVA model
c How would you interpret the results in Tables 1 and 2
d What additional computation can be done to evaluate the importance of the
different effects in Table 1
e Using the results in Table 2 show the G x M effect in a graph (It is OK to draw
this graph on a separate sheet and turn it in with your exam)
f Explain what type I and type II error mean in the context of this study

J) Meta-analysis
J1 There exist two categories of literature review narrative and quantitative Each
category as typically implemented has certain advantages and disadvantages
Describe the advantages and disadvantages associated with each approach taking
particular care to enumerate the disadvantages associated with quantitative review
Then offer two ways that meta-analysis might be combined with other analytical
techniques to move beyond the focus of bivariate relationships that is typical of meta-
analysis

scientific laws but that meta-analytic research does What are the arguments in favor
of or against this position In what areas of research (if any) has Schmidts
prediction come closest to coming true
J3 The so-called (by Hunter Schmidt and Jackson 1983) state of the art meta-
analysis method attempts to account for various sources of error that might produce
apparent variation in effect sizes across studies (a) Discuss the three most important
sources of error that meta-analysis addresses (b) Discuss the potential contribution
that a meta-analysis can make to theory building in the organizational sciences (c)
Describe the circumstances that you would consider when deciding whether to
perform a meta-analysis
J4 Meta-analysis has been hailed as a miracle cure and criticized as smoke and
mirrors Explain both sides of the debate and then lay out the role of meta-analysis
as you see it within the time span of your career as an academic To do this use
examples of already written (or yet to be written) articles as models
J5 A frequent criticism of non-quantitative research summaries (literature reviews) is
that researchers do not carefully examine how particular research designs might have
affected the statistical outcomes of the studies included in the literature review Meta-
analysis however allows one to statistically examine such effects Assume you are
conducting a meta-analysis of the relationship between leader behaviors and group
productivity Briefly describe the steps you would take in conducting a meta-
analysis What aspects of the original research designs would you examine in your
meta-analysis What steps would you take in gathering and coding data to enhance
the credibility of your analysis
K) MTMM
K1 One method often used by social scientists to demonstrate the construct validity of
measures is the multi-trait multi-method matrix developed by Campbell and
Fiske (1959) Briefly describe how this matrix is obtained or constructed by a
researcher and then describe how each of the elements of the matrix is used to
demonstrate the reliability andor construct validity of the measure(s)
IC
K2 Describe the logic of the multi-trait multi-method (MTMM) analysis in terms of
the criteria for evaluating the validity of a set of measurement procedures
Interpret the following MTMM in terms of what it might infer about the validity
of the different measurement procedures You may impose any assumptions on
the data you prefer For example you might want to discuss the matrix under the
assumption that traits A B amp C are mutually independent Please justify and
make explicit any assumptions you make

and discuss the assumptions of the general linear model Multiple regression
ANOVA and principle components (factor) analysis are based on the general linear
model For each of those three statistical procedures describe and discuss the
following
a The type of data necessary for using the technique appropriately
b The type of output that results from applying the technique

O) Exploratory Factor Analysis and Confirmatory Factor Analysis
O1 Contrast Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis
(CFA) Give an example for the appropriate use of each of the above analyses
What is the role of theory in the two factor analyses
IC
O2 Compare and contrast Exploratory Factor Analysis (EFA) with Confirmatory TH
Factor Analysis (CFA) Put more emphasis on their theoretical basis
assumptions usage and limitations
O3 How do exploratory and confirmatory factor analysis differ What are the
advantages and disadvantages of each
O4 Describe the differences between exploratory factor analysis (EFA) and
confirmatory factor analysis (CFA) When would you use one verses another
Are there ways to use EFA in a confirmatory way Can you use CFA in an
exploratory way Also describe the difference in principal components analysis
(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression
O6 The basic factor analysis model can be represented by the matrix algebraic
equation A B = C

information in each matrix and its purpose
(2) For what purpose do researchers use factor analysis Explain In the process
provide a very brief description of a study for which factor analysis would be a
useful data analytic technique

P) Structural Equation Models
P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)
Please comment on these restrictions versus access argument Which side do you
take
What are the strengths of SEM Give some examples
What are the weaknesses of SEM Give some examples

d Can a discipline be said to progress within the context of discovery
A7 An epistemology is a set of rules for the appropriate way to generate knowledge
Outline the major components of your epistemology for Organizational Studies
research You may wish to proceed by identifying one of the established
epistemologies and comparing it to yours (eg skepticism positivism
empiricism pragmatism relativism) Describe the process by which you feel
knowledge can be generated most effectively in Organizational Studies Identify
and define the key concepts of your research philosophy and discuss its
strengths and weaknesses
A8 Abraham Kaplan argues that behavioral scientists should practice openness in
inquiry that is they should not pre-judge research or theory negatively or
positively on the basis of its content There are many other competing
philosophical schools of thought as to how empirical research should be
conducted Much of the debate has addressed the following issues
a What are the criteria for judging whether research is worthwhile Is there
some research that should not even be done
b What is the most effective model of the research process
c How does a researcher determine the meaningfulness of a research finding
That is what are the rational rules of evidence necessary for evaluating research
findings
In your doctoral studies you have been exposed to a variety of approaches for
addressing each of the above issues Please describe in detail your position on
these issues and provide citations where appropriate In addition please
highlight the major competing positions on each issue
A9 In recent years there has been considerable debate in the social and behavioral
sciences concerning the two competing epistemologies-- logical empiricism
(including falsificationism) and relativism (ie post-positivism)
a What characteristics distinguish these two epistemologies Be sure to address
both conceptual and methodological differences
b Take the perspective of a logical empiricist How would this perspective
affect the manner in which you conduct research Be sure to discuss at least the
following issues a) what model(s) would you use to approach the research
process b) theory evaluation and c) data collection
c Now take the perspective of a relativist Address the same issues raised in part
b
A10 In recent years there has been considerable debate in the social and behavioral
sciences concerning two competing research paradigms--one based on a logical
empiricismrealist epistemology and the second based on a post-empiricist
epistemology These paradigms vary with respect to their underlying aims
(goals) standards for judging explanations and ontology
a Describe the basic aims standards and ontology for each paradigm What
characteristics distinguish these two paradigms
b One current concern focuses on the appropriateness of a priori and post-hoc
explanations for theory testing Describe and defend your point-of-view
concerning which type of explanation is appropriate for research in
organizational studies
c A second current concern focuses on the appropriate treatment of the
independent variables that is an experimental approach (where the independent
variables are manipulated) and an observational approach (where the
independent variables are observed) Describe and defend your point-of-view
concerning which treatment of the independent variables is likely to produce the
more important contribution to organizational studies
A11 What rules of evidence are used by the positivist research paradigm to determine
whether a research finding is meaningful Choose another research
philosophyparadigm and compare and contrast it to the positivist rules of
evidence
A12 A major tenet of research is that research subjects should have limited if any
knowledge of the subject of the research The assumption is that subjects will
not act naturally if they are aware of the purpose of the research For this reason
researchers often engage in various types of deception For example
experimental and survey researchers will word instructions in such a way as to
hide the research goals and researchers who conduct participant observation
will avoid telling people they are researchers Discuss the ethical questions
raised with deception What guidelines would you give to a colleague who was
conducting research that involved deception
B) Causation
1) Explain the phrase ldquocorrelation does not equal causationrdquo Why is the distinction so
important What conditions must be met to establish causation Can they ever be
completely satisfied
12) Why is a posttest only design without random assignment to treatment conditions
uninterpretable from a causal standpoint
B1 Choose a model from the Organizational Behavior literature that has causal
orderings between variables and has been tested in a field setting Compare the
following data analytic methods for testing hypotheses about causality between
variable sets (eg dependent independent intervening moderating exogenous
endogenous)
a) path analysis using hierarchical regression
b) maximum likelihood estimates of structural equations models (perhaps through
LISREL)
Your answer should address
1 The parameters the procedures estimate and how they are estimated
2 How the validity of the models are judged
3 Appropriate inferences of causality and conditions necessary to make such
inferences
4 The statistical assumptions underlying each technique and the consequences of
violating assumptions
B2 Describe the critical-realist perspective of Cook and Campbell (1979) Compare and
contrast this perspective on causality with that of Poppers falsificationism
B3 According to Cook and Campbell (1979) causal relationships in the social sciences
can be probabilistic and still meet the assumption of causality that asserts that a
cause must always produce an effect Describe the logic they invoke to justify this
position
B4 Identify James Mulaik amp Bretts (1982) conditions for establishing causal
inference Discuss what they mean and why they are important to causal inference
B5 What are the three conditions necessary to establish causality Can these conditions
ever be fully met Why or why not
B6 Assume you are interested in conducting a study that allows you to legitimately
make some causal inferences concerning relationships among a set of constructs
What sorts of things can you as the researcher do to bolster your ability to make
such causal inferences In answering this question be sure to pay attention to issues
pertaining to both study design and data analysis
B7 Some researchers (and editorsreviewers) are very critical about the ease with which
others use causal language in interpreting their analyses What are the concerns
behind this criticism and what are the methodological and statistical conditions that
give rise to these concerns Under what conditions can researcher make reasonable
valid causal interpretations of their findings Can a researcher ever be completely
confident making such causal statements Be sure to defend your position in
answering these questions
C) Theory amp Research
C1 What are the elements of a theory What criteria did Bacharach (1989) use to
evaluate if a theory is good
IC
C2 The Academy of Management Journal in its Information for Contributors
states All articles published in the Journal must make a strong theoretical
contribution Because this is one of our top publications we must have a clear
understanding of what constitutes a strong theory Describe the essential elements
of a good theory You can also describe practices that are not indicative of good
theory if that will help you articulate what is good theory
C3 Organizational researchers place a high premium on research that is guided by
theory This perspective is evident in journals such as AMJ and ASQ which will
often reject a manuscript that describes a sound empirical study but does not
provide a theoretical contribution Is there a role for atheoretical research in the
organizational sciences If so what is the role of atheoretical research and what
contribution does it make to knowledge in the organizational sciences
TH
C4 Define inductive and deductive methods for generating knowledge What are the
advantages and disadvantages of each Under what conditions is each
appropriate
C5 Daft (1985) in Why I Recommended That Your Manuscript Be Rejected and
What You Can Do About It said that poor theoretical development is the
primary reason he recommended manuscripts be rejected when reviewing for
AMJ and ASQ
Why is theory considered so important
Give an example of a good theory and explain the elements that make it a strong
theory (Focus on theory development not on the content of the specific theory)
C6 You have undoubtedly heard the criticism of certain published articles in our
field being atheoretical Spoken as a criticism it suggests that research articles
should have theory Should every empirical article have theory Why is theory
important What are the hallmarks of good theory
2 RESEARCH DESIGN
A) Research Design Terms
5) Define internal and external validity Which is more important and why (It is not okay to
say they are equally important)
A1 Define (and discuss important features or issues concerning) the following
constructs of research design (Define any five terms)
1 Internal validity 6 Quasi-experimental
design
2 Stratified Sampling 7 Random Assignment
3 Solomon Four-group
design 8 Differential mortality
4 Factorial design 9 Demand
characteristic
5 External validity 10 Regression to the
mean
B) Level of Analysis
B1 IO psychologists have traditionally categorized themselves as being more micro or
macro in orientation usually falling toward the micro end Recent concern for what
has been termed the levels of analysis or cross-level approach has added a third
category - meso What is the meso level Is this just academic hairsplitting or re-
naming or is there a fundamental difference in this research strategy in contrast to
micro or macro Provide an example from some research domain of interest to you
that illustrates your conclusion of no real difference or important difference
C) Cross-Sectional vs Longitudinal Design
13) What are the benefits of a longitudinal design over a cross-sectional design in a non
experimental (correlational) study What are the disadvantages Why donrsquot we see
more longitudinal research
C1 The use of cross-sectional research designs continues despite many calls for
replacing them with longitudinal designs (a) What are the main strengths of
cross-sectional designs (b) What weaknesses do they have that longitudinal
designs supposedly counter (c) What are the implications of cross-sectional
designs for theory development (Consider internal and external validity)
C2 A good number of research efforts on the micro (OBHR) side rely on cross-
sectional designs in which surveys are used to collect both IVs and DVs from the
same respondent What are the various problems associated with such a design
What changes could be made to this design to alleviate andor eliminate these
problems What are the downsides of the new design (add in conveniencenon
probability samples)
C3 What are some of the major strengths of a longitudinal design Why dont we see
more of them
C4 Assume that you are analyzing a large sample of longitudinal survey data TH
Identify two characteristics of your data that would make ordinary least squares
regression (OLS) inappropriate for conducting analyses For each of these
characteristics describe an alternative analysis that is superior to OLS
D) Qualitative vs Quantitative Designs
D1 Compare and contrast the objectives strengths and weaknesses of
qualitativeobservational methods (eg ethnography) versus quantitative methods
(eg survey) in conducting empirical research on macro organizational issues Be
sure to consider issues of reliability generalizability validity ethics and
practicality in your answer Describe situations where one method or the other
may be most appropriate
IC
D2 In recent years a number of individuals have taken the position that qualitative
research is superior to quantitative research a Compared with quantitative
research what are the principal strengths of qualitative research b Compared
with quantitative research what are the principal weaknesses of qualitative
research
E) Observation vs Experiment
E1 Compare and contrast the objectives strengths and weaknesses of observational
methods (eg ethnographic methodology) and experimental methods Be sure to
consider issues of precision generalizability and realism in your answer Consider
also situations where one methodology or the other might be most appropriate
F) Laboratory vs Field Research
F1 Of the various research approaches available to organizational researchers
laboratory experiments are held up as an ideal because of their potential for high
internal validity On the other hand field research including participant observation
and field experiments have high potential for external validity Discuss specifically
the strengths and weaknesses of laboratory versus field experiments How would
positivist researchers think differently about these tradeoffs than would
phenomenologists
F2 In conducting an experiment in the laboratory or designing survey research there are
certain unique opportunities and limitations of each research strategy A) Describe a
hypothesized relationship between two constructs an independent and a dependent
variable in a substantive area of your choice (eg Strategy OB HRM
Organizational Theory) provide a verbal mathematical and graphical statement of
that hypothesis B) Briefly discuss how you would examine this hypothesized
relationship in a laboratory using experimental techniques versus a field survey using
correlation techniques C) Discuss what may be considered typical strengths and
weaknesses of each strategy regarding issues of precision and control in the
manipulation or measurement of the variables of interest realism of the context for
the participants and generalizability of the findings to other elements of a chosen
population D) Finally discuss advantages if any of using laboratory and field
survey methods in tandem
G) Experimental Design
2) A colleague suggests to you that only true experiments can provide useful results in
science Why might she say this What would you offer as a defense for the role of quasi-
experimental and non experimental designs in the context of the social science In
answering this question make sure you identify the defining characteristics of each design
type
9) Why and when should we be concerned about non response in research What are the
things we can do to try and decrease non response (or increase response rates)
11) Why might a researcher choose to utilize an experimental design that incorporates pretest
measure on the DV
G1 Experimental designs oftentimes come under attack due to perceived limitations in
external validity (a) Relative to other design types what strengths and weaknesses
do they offer (b) What experimental design structure is the strongest Why (c)
What is the relevance of research design for results and theory development
G2 Meta-analysts often investigate whether the quality of research design (eg
randomized experiments vs non-randomized designs) influences average effect
size In their meta-meta analysis of psychological educational and behavioral
treatments Lipsey and Wilson (1993) found that In a given treatment area poor
design or low methodological quality may result in a treatment estimate quite
discrepant from what a better quality design would yield but it is almost as likely
to be an underestimate as an overestimate (p1193) A few methodologists (eg
Shadish) have attempted to identify factors that may explain the relative magnitude
of effect sizes from randomized and nonrandomized experiments Please review
these findings and add your tentative model of the conditions under which random
experiments will produce larger smaller or equal effect sizes relative to
nonrandom designs Discuss possible implications for research design in the
context of real-world interventions
G3 Analysis of covariance and randomized blocks designs are sometimes referred to as
noise-blocking designs Explain what this means and give an example of (a) a
randomized blocks experiment and (b) an analysis of covariance experiment Keep
your examples simple Describe how such designs are noise-blocking when used
with randomized assignment of subjects to experimental condition and contrast
that with the role such designs serve in quasi-experimental designs
G4 Team performance in Bafko Industries varies considerably across teams and from
month to month The senior VP in charge of team development thought that a team
training program could improve the performance of these teams A consultant
convinced him that his firms training program which lasted only one week and
cost only $25000 per team) could raise the performance of Bafkos teams The VP
however wanted to experimentally test the efficacy of this training program before
he adopted it widely throughout the firm So the consultant suggested the following
experimental test
There were 48 teams in Bafko that showed significant variation from month to
month in their level of performance The consultant chose the 24 worst performing
teams based on last months data and assigned them to the training group After
all he argued these were the ones who most needed it The other teams were
assigned to the control group The training group received the training program
(lasting one week) at the beginning of the next month while the control group
teams did their normal routine Performance scores were gathered at the end of the
month The results showed that the training group teams had a significantly larger
rise (ie statistically significant) in their performance than did the control group
teams (who as a group did not improve at all) The consultant proudly displayed
these results and argued that they convincingly demonstrated the efficacy of his
program
How would you advise the VP Specifically what is the validity of the consultants
conclusions If you think he might be mistaken what specific threats to internal
validity are particularly plausible
G5 Consider the following design
N O Xa O
N O Xb O
N O Xc O
N O O where
Xa Xb and Xc represent different levels of a training program that varied in its
length across three different work groups In group a the training time was 40
hours in group b it was 30 hours and in state c it was 20 hours The training was
designed to instill customer service values in the team members O represents a
measure of customer service attitudes measured with a 20-item Likert scale This
measure was administered one week before the training program and 3 months
later The researcher hypothesized that the training program would improve
customer service attitudes and that longer training would have stronger effects
The design is a non-equivalent groups design because people were not randomly
assigned to groups even though groups were randomly assigned to treatment
condition Each group has a sample size of 36 members The reliability of the
customer service attitude scale was 78 at the pretest and 80 at the posttest The
pretest means were as follows
Group A 26
Group B 23
Group C 27
Control Group 25
a Construct a regression model that will test the researchers hypothesis Be
explicit here describing each variable in the model and what regression effect(s)
you would expect to find if the hypothesis were correct (Hint everything you need
to know is in Trochims chapter 11 and what we discussed in class) (10 points)
b Describe any serious threats to internal validity (10 points)
c Discuss how you might amend this design to improve its internal validity(10
points)
G6 Often in organizational research the researcher is faced with having only one group
on which to experiment and thus cannot use a control group when conducting
experiments This occurs for example in taxation experiments when you cannot
selectively apply new tax laws to different groups or when you wish to test the
efficacy of an incentive plan that must be applied to all members of a company In
such situations the researcher must be creative in assembling a quasi-experimental
design that has high validity (and usually the challenge concerns internal validity)
Consider the following scenario
A manager of a retail store wants to test the efficacy of an incentive program in
changing the selling behaviors of her retail sales clerks Specifically she wants to
test a behavioral reinforcement program in which sales peoples behavior is
recorded on in-store video cameras The tapes are analyzed each night and the
experimenter tabulates the frequency of various behaviors (eg offering assistance
to customers restocking items straightening up displays suggesting accessory
items to accompany the items that a customer is purchasing) The manager then
rewards the clerks with a monetary bonus based on the frequency of desired
behaviors She would like to conduct a valid experiment to see what effect such an
incentive program has on employee behavior but because of concerns about
employee morale she cannot assign clerks to treatment and control groups Instead
she has to apply the experimental treatment to everyone in the store She learned in
her research methods class (which the company requires all its managers to take)
that a single group experimental design typically has very low internal validity
Your job as a consultant is to help her design an experiment given her constraints
that would produce interpretable (ie internally valid) results Describe the details
of the design you would recommend using the notation in Trochim (2001) If the
design you come up with has a specific name use it As part of describing your
design discuss how the data would be analyzed and what particular effect you
would look for
G7 Why are experimental research designs held in such high regard
G8 Compare and contrast experimental quasi-experimental and correlational research
designs What characteristics separate these three designs What are their
advantages and disadvantages especially in comparison to one another
G9 What is the difference between a within-subjects experimental design and a
between-subjects experimental design When might a within-subjects design be
appropriate When might it be inappropriate
G10 Describe the difference between a basic within subjects and between subjects
experimental design What are the advantages and disadvantages of each
especially in comparison to one another Give an example from your area of
research in which each would be appropriate
G11 What are the major threats to the internal validity of a pretest - post test
nonequivalent control group design How can this design be improved with regard
to increasing a researchers ability to make causal inferences
G12 A production manager is interested in testing the hypotheses that participation in
quality circle programs will result in increased productivity and reduced
absenteeism A questionnaire is administered to a group of 92 employees
concerning their attitudes toward such programs and 46 with the most favorable
attitudes who are willing to participate are selected for the treatment group The
remaining 46 are the control group Measures of performance (unitsmonth for the
group) and absenteeism (lost daysmonth for the group) are kept over a three month
period during which the treatment group has weekly quality circle meetings The
results are as follows
Month 1 Month 2 Month 3 Month 1 Month 2 Month 3
Performance Absenteeism
Treatment 100 115 121 6 9 4
Control 110 108 113 6 8 5
The manager calculates t tests between month 1 and 3 The only significant
difference is performance for the treatment group so the manager concludes that
quality circles raise productivity but do not have an effect on absenteeism What
are the primary threats to internal and external validity in this study What are
possible alternative explanations for the differences (or lack of differences)
between the two groups What additional information might help explain these
results
G13 One stream of current strategy research contains event studies In these studies
investigators basically correlate the reaction of a financial market to the presence
andor absence of the occurrence of some event at a firm (eg the resignation of a
CEO) In a different approach to such a study suppose that one investigator (Jean)
conducts a natural field experiment on the effects of competitor mergers on a
firms environmental scanning activity Through previous arrangement Jean has
been working with 5 medium-sized computer hardware and 5 medium- sized
software firms on the west coast Shes been collecting a paper trail of internal
memos reports and phone calls that might measure environmental scanning
activity Shes been finding that the firms in both industries do about the same
amount of scanning (no significant differences) However in the midst of her data
collection Norton announces a merger with Symantec (software) A year later
Jean compares the amount of post-merger environmental scanning in the software
industry with that in hardware industry Just as Jean had hypothesized a t-test
shows a greater amount of post-merger scanning among the software firms She
concludes that her hypothesis was supported mergers of competitors cause an
increase in scanning
Critique the study described above in terms of its design flaws Identify the design
Jean used Briefly allude to problems the study has with external validity but
concentrate on the Cook and Campbell threats to internal validity Provide a
rationale for why each threat is or isnt operating in the study Link each of the
relevant threats to the specific constructs being studied (mergers and environmental
scanning) Finally do a summary evaluation -- what can be learned from this
study
H) Quasi-Experimental Design
H1 The University of Mississippi observed that the graduation rate of students with poor
grades during their freshman year was much lower than those with better grades
Wanting to improve the chances of these low performing students they tested the
effects of a new rule for freshmen The rule stated the following At the end of their
first semester all students with a GPA between 200 and 225 must register for
EDUC 1003 during their second semester Students with a GPA lower than 200
were put on academic probation EDUC 1003 consisted of a course whose objective
was to help students develop good study skills The theory was that poor study skills
were a significant cause of poor academic performance and that study skills could
be learned
They wanted to evaluate the effectiveness of this intervention so they collected data
on the GPAs of students beginning with their first semester and continuing through
to their third semester At that point they wanted to analyze the data to determine
whether the new rule was making a significant difference in the students academic
performance
What is the best way to analyze these data to reach an interpretable conclusion
Describe your approach and then discuss the major threats to validity that it has
Their sample size of students was as follows
Total N= 3454 (these are students who completed all 3 semesters)
Number of students with first semester grades between 200 and 225 (and thus took
EDUC 1003) was 956
H2 A nationwide furniture company wants to determine if a diversity training
program will improve individual sales performance on the floors of its urban retail
outlets A group of 45 salespeople in one city were given two weeks of training
Measures of individual sales performance were taken once two months prior to the
program and once two months after Forty-five salespeople (who did not receive the
training) in a similar city had the same measures taken at approximately the same
points in time The training group increased their average weekly sales from $14000
to $16500 while the non-training group improved theirs from $13000 to $14500
The change for the training group is statistically significant the change for the non-
training group is not
How would the interpretation of these results in this quasi-experimental design
differ from a true experimental design What are the threats to internal validity in
the above study and how might they be operating (be specific) What additional
information and analyses would be useful in controlling for these threats
H3 An accounting firm is interested in determining if a re-training program will reduce
errors made by its audit teams A group of 45 auditors in the home office location
are given two weeks of re-training Measures of the frequency of detectable errors
are taken once two months prior to the program and once two months after Forty-
five auditors in similar office at a branch location have similar measures taken at
approximately the same points in time The training group reduced their average
number of errors per audit from 8 to 3 while the non-training group reduced theirs
from 11 to 9 The change for the training group is statistically significant the change
for the non-training group is not
How would the interpretation of these results in this quasi-experimental design
differ from a true experimental design What are the threats to internal validity in
the above study and how might they be operating (be specific) What additional
information and analyses would be useful in controlling for these threats
H4 Describe the main classes of threats to validity that are found in quasi-experimental
research designs
H5 Dr Delta an organizational development consultant was hired by a firm that has
600 pizza parlors nationwide to assist in implementing organizational changes that
he hopes will result in higher levels of job involvement At the outset of the study
subjects had jobs with very low levels of enrichment and were paid on an hourly
basis He designed an experiment in which stores were randomly assigned to one of
three treatment conditions Condition 1 subjects experienced job enrichment (JE)
and a change to performance-based pay (PBP) Condition 2 subjects experienced
only JE and Condition 3 subjects experienced only PBP The parlors were
sufficiently far apart from one another and communication among the parlors so
poor that subjects in any parlor were totally unaware of changes made in other
parlors At the end of 18 months he measured the job involvement levels of workers
and then tested for differences between the three conditions using a standard one-
way analysis of variance In view of Dr Deltas design answer the following
questions
How sound is Dr Deltas design Comment on the weaknesses of the design
I) Interrupted Time Series Design
I1 What threats to internal validity are and are not ruled out by an interrupted time series
design that includes the introduction of a treatment and its removal at a subsequent
time period List and explain In the process be certain that you provide a diagram
that illustrates such a design
J) Validity Some Questions are about the validity of a measure others about experimental validity)
10) Identify four threats to internal validity and briefly describe what they mean
J1 It was some time ago that the tripartite view of validity was abandoned in favor of a
unitarian view in which different evidentiary bases for validity might be put forward
Binning amp Barrett (1989) represent an attempt to place multiple evidentiary bases into a
single framework Cook amp Campbell (1979) describe four aspects of validity but they
arent really meant to represent evidentiary bases Adding to the confusion is the fact
that while Binning amp Barrett and Cook amp Campbell use some of the same terms these
two pairs of authors clearly mean different things by these terms and intend for them to
be used in different ways Your task is to 1) Describe the evidentiary bases discussed
by Binning amp Barrett 2) Describe the aspects of validity described by Cook amp
Campbell 3) Describe the similarities and differences between the two lists including
the different purposes served by the two lists and 4) Present a single framework that
incorporates both This last task is the most important of the four
J2 What are the types of validity How would each affect an empirical study IC
J3 Define both internal and external validity Which is more important (it is not okay to
say that they are equally important) Defend your reasoning
J4 Why might someone argue that the construct validity of a measure can never really be
established
J5 Describe each of the following forms of validity content convergent discriminant
criterion-related and construct How is each assessed How do they related to each
other Which is most important (Make sure you defend your answer)
J6 Define and explain 6 of the 8 types of validity listed below and describe the type(s) of
information each provides Choose one specific type of study as an example (eg
cross-sectional study experiment quasi-experiment simulation ethnography etc) and
compare and contrast the usefulness and importance of each type of validity for that
type of study
-- Concurrent validity
-- Construct validity
-- Content validity
-- Convergent validity
-- Discriminant validity
-- Statistical conclusion validity
-- Internal validity
-- External validity
J7 Designing empirical research has been called making a series of trade-offs
Unfortunately decisions that are made to increase one desired quality (like internal
validity) can also decrease another desired quality (like external validity) For each of
the issues below discuss the concerns involved (ie the trade-off) and identify the
qualities that are being increased or decreased
a laboratory vs field study
b using a 5-item measure vs a 1-item measure
c using a student sample vs a sample of full-time employees
d using a sample of employees from one company of 5000 vs 500 employees from
each of 10 companies
e collecting your data using one method vs collecting your data using multiple
methods
J8 There are four major types of validity in social science internal validity external
validity construct validity and statistical conclusion validity Please address the
following three issues concerning validity
a What is the meaning of the four major forms of validity (ie internal and external
validity construct validity statistical conclusion validity)
b Are there trade-offs that can or must be made among the four types of validity
d Describe how the concept of validity varies across the research traditions of
experimental vs observational research
IC
J9 The quality of research is often assessed by examining validity issues As you are
aware there are numerous typesforms of validity (eg internal and external validity
construct validity statistical conclusion validity) These types of validity address
different aspects of the research process For this question please address the following
issues
a What is the meaning of the four major forms of validity (ie internal and external
validity construct validity statistical conclusion validity)
b Should there be a priority among these forms of validity If yes why If no why not
c Does the concept of validity vary across research traditions (ie experimental vs
observational research) If yes why If no why not
J10 External validity has received considerable attention in the social and behavioral
sciences Some researchers argue we are too concerned with the external validity of our
findings while other researchers argue that we are too unconcerned with external
validity Several points of view have been developed to explain what is external
validity When answering this question please be sure to address at least the following
issues
a Compare and contrast alternative conceptualizations of external validity
b Some researchers have argued that the role of external validity is invariant across
research traditions (ie experimental vs observational research) Defend the
perspective that the role external validity is invariant across these two research
traditions In addition present the weaknesses of this perspective
J11 In designing a research study researchers must consider trade-offs between internal and
external validity Explain what is meant by internal validity and external validity What
is the nature of these trade-offs How would you evaluatedetermine which is more
important internal or external validity for a particular study Why is this such an
important issue in organizational studies
J12 A researcher conducted a quasi-experiment to test the effects of participative decision
making (PDM) on job attitudes of employees Employees from different departments in
a large organization were assigned to either a treatment group (PDM implemented) or a
control group (no PDM) Random assignment was not possible because of work
schedules coordination of tasks etc Thus the design can be considered an untreated
control group design with pretest and posttest and is represented as follows (where
O=observation X = treatment)
________________
O1 X O2
-------------------------
O1 O2
_________________
The results of the experiment are presented in the graph below [no graph provided]
The dependent variable is job satisfaction and is measured on a 100 point scale (with
100 being extremely satisfied) How amenable are these results to causal interpretation
What is (are) the major threat(s) to internal validity B if any B for this type of design
given these results What steps can be taken to assess the extent of this (these)
threat(s)
K) Data Collection Methods
14) Describe the various methods of data collection (eg survey interview observation etc)
available to a social scientist What are the advantages and disadvantages of each relative to
each other
K1 Within micro organizational research much criticism has been raised concerning
the reliance on self-report survey data What potential problems does self-report
survey research raise How big of a problem do you think this is
K2 There are a number of methods for collecting data (eg survey interview archival
etc) that are available to a social scientistorganizational researcher Discuss each in
terms of their strengths and weaknesses both on their own and in comparison to one
another
K3 Pick an important construct in your favorite area of management research for which
there is some controversy about how it should be measured or operationalized (eg
environmental munificence or growth need strength) Give the prevailing verbal
definition of the construct and analyze the measurement controversy from two
broad angles First discuss how the controversy may or may not stem from claims
about how one measure is better or worse than another because it (or the other) is an
(a) archival record (b) direct observation (c) social report or (d) self-report That is
what are the relative strengths and weaknesses of each of these types of
measurement for the construct youre discussing Second discuss the construct
validity of the most commonly used measure(s) of this construct To answer this
second part you need to discuss just what construct validity is and how it can or
cannot be demonstrated In the situation you describe what could be done to
demonstrate or improve the construct validity of existing measures
K4 Interviewing in some form has been the workhorse for data collection in a variety
of research traditions positivistquantitative ethnographic feministpost-modernist
and increasingly historical research While each tradition elicits information from
respondents the goals and processes involved in interviewing vary considerably
across research traditions Discuss the purposes of the interview the relationship
between data and theory the roles assumed by the interviewer and the respondent
and the relevant criteria for assessing the validity and reliability of the information
obtained In addition compare and contrast the use of the interview as a data
collection method in the positivistquantitative tradition with its use in one of the
alternative traditions
L) Common Method Variance
L1 Many of us have had concerns about the reviews of our survey research which
suggest that data analyses of surveys are biased because of common method
variance effects of individual differences such as negative mood negative
affectivity and social desirability and the reliability and validity of the constructs
we are attempting to measure Define how these problems affect a research issue in
organizational behavior and the steps that might be taken to minimize such potential
criticisms of papers based on analyses of self-reported data through survey
instruments
L2 In a series of papers by Spector (1994) Schmitt (1994) and Howard (1994)
published in the Journal of Organizational Behavior arguments were provided for
and against the use of self-report questionnaire measures One of the issues
discussed that could limit conclusions drawn from relationships observed using self-
report measures was method variance What is meant by method variance what are
its sources and what impact is it expected to have on research findings
M) Sampling
M1 The manufacturing census samples all plants of 250 employees or more For
plants of 5-249 employees it takes a size proportional sample Plants of 1-4
employees are not sampled What challenges does this sampling method provide
to researchers What could you do to account for these problems if you were
TH
studying organizational (not plant) growth
M2 New York State has approximately 250000 employees in over 70 state agencies
commissions and boards ranging in size from approximately 50 to over 5000
employees Assume that you wanted to draw a representative sample of 1000
employees Describe two ways that you could draw such a sample and briefly
describe the advantages and disadvantages of each of these sampling approaches
IC
M3 The director of a national non-profit agency with approximately 10000
employees located primarily in regional offices in each of the 50 states the
United States has approached you and asked you to develop a study
(organizational survey) of organizational culture within the agency The agency
is about to embark on a variety of change initiatives including developing team
structures and the study is meant to examine various elements of organizational
culture that are potential barriers to change The director has indicated that he
would like to have the data analyzed at both the individual and office level of
analysis Because of funding limitations the agency will only be able to send the
survey to 1000 employees The director has indicated that there are three ways
of sorting employees all employees listed alphabetically all employees listed
alphabetically by state and all employees listed alphabetically by region (there
are between five and ten regions per state) Given these three ways of sorting
employees describe at least three different sampling approaches and the
advantages and disadvantages of each
M4 In your role as Teacher of Organizational Studies you are asked to prepare a
tutorial for beginning doctoral students on sampling design Assume that this
tutorial is part of a basic class in research design and that students in this class
have had a basic statistics course up to and including multiple regression Your
tutorial should focus on briefly defining and explaining the differences between
probability and non-probability samples You should make sure to present and
describe several types of probability samples (eg random systematic
stratified etc) and non-probability samples (eg convenience snow-ball quota
etc) and discuss general principles for when to use a probability vs a non-
probability sampling design For each sampling design you should also provide
at least one clear example of a situation where this type of sampling design is
appropriate
N) Cross-Cultural Research
N1 Discuss the problems in conducting cross-culturalnational comparison in terms
of (1) conceptualization and (2) research design and data collection
Define the three levels of measurement invariance How would the problems that
you have identified in part (a) affect measurement invariance How would you
examine measurement invariance by confirmatory factor analysis
TH
N2 Explain why using national boundaries as independent variable in cross-cultural
studies may not be appropriate in terms of theory and research methods What
alternative ways would you recommend
IC
O) General
O1 In your readings research has been described as choices among conflicting goals
(desiderata) For instance when choosing among research strategies a researcher
must choose among the desiderata of precision realism and generalizability The
trade-offs among desiderata occur for all aspects of research that is for the selection
of theories the treatment of independent variables research strategies the selection
of the problem to study rules of evidence for determining the meaningfulness of a
research finding and even the frameworks that describe the research process
Discuss what you see as the major trade-offs for each of the following aspects of
research That is discuss what you see as the major strengths and weaknesses
(advantages and disadvantages) of each aspect
a The trade-offs between internal and external validity
b The manipulation of the independent variable vs the observation of the
independent variable
c Basic vs applied research
3 DESIGNING A RESEARCH STUDY
A) General (Research Design)
3) Why is control so important in research design What are the different ways it can be
achieved (give a brief description of each control method) What are advantages and
disadvantages of each
A1 It has become almost a truism to note that the choice of methods influences theory
and questions data and conclusions (the causal direction might also be reversed)
Briefly discuss how the methods used have influenced research in any two of the
following areas leadership power and politics organization culture organization
justice Compare and contrast as possible Suggest some potentially fruitful
methodological directions for future work in these same topical areas and dont be
shy about reflecting on broader issues of how the field of organizational behavior
constructs its realities Lastly tie your discussion and reflections back to your own
future as a researcher what lessons or guidance do you derive from your
understanding of these issues
A2 Characterize as fully as possible what you see to be the methodological approach or
approaches in strategic management research Is there a dominant method or a wide
variety Discuss the reasons for the situation What are the advantages benefits etc
of the approach(es) in use What assumptions (ontological epistemological
ideological) do they embody Are current efforts ideal or at least adequate Are
there other approaches that could be useful If so how might researchers be
encouraged to use these as well If you see no advantage to more variety in
methodological approach support that point of view
A3 Describe a research question or area of interest to you and why you think it is not
only of interest but significance Using your understanding of research methodology
describe two ways of pursing the question that are as divergent on as many
dimensions as you can imagine Describe the advantages and disadvantages of each
approach How strong a link or fit is there between a research question and a
method
A4 In his 1957 article entitled The two disciplines of scientific psychology Cronbach
discussed the assumptions goals and methods used in experimental methods and
correlational methods in psychology
a According to Cronbach what is the main difference between the two disciplines
b Discuss the strength and weaknesses of each discipline
c What if anything could be done to improve the situation
B) Designing a Research Study
B1 Cook and Campbell describe the experiment as the research design with the
greatest methodological rigor However given the constraints present in most
organizations I-O Psychologists cannot often conduct experiments in applied
settings and must settle for techniques with less control than experiments
Describe a study to investigate the relationship between participation in a
supervisor training program and work performance which could realistically be
conducted in an organization If an experiment is not possible describe how you
would go about maximizing your ability to draw valid conclusions from your
design
B2 The XYZ Co has recently developed a sexual harassment web-based training
program The developers claim the program will cut training time and costs and
will be as effective or more effective than classroom-based sessions They
believe that this will be due to the increased availability of the program and the
ability for participants to review program material on demand Before the XYZ
Co developers launch this product they want you to determine if their claims
have merit Explain how you would design a study for this purpose
B3 Research suggests that demographic diversity improves group creativity but
reduces group efficiency Some argue that demographic diversity is just a proxy
for value and experience diversity and that demographic diversity on its own is
meaningless Design a test to settle this argument
TH
B4 E-mail has become a common form of communication in organizations and is
used for both formal and informal communication Because it has become so
IC
popular some people complain that the frequent use of e-mail leads to
miscommunication because they receive communications in e-mail that should
be accomplished through face-to-face or telephone conversations where there is
an opportunity for interaction You are interested in looking at this
phenomenon You are most interested in describing how e-mail is used for both
formal and informal communication and in examining the effect of the e-mail
use on organizational communication effectiveness Design empirical research
to address those issues
Describe your study in detail thoroughly explaining the research design
sampling plan data collection procedures ethical issues and proposed data
analysis for your research design Be sure to discuss the internal and external
validity of your research Which validity threats are ruled out and which
remain
REMEMBER Be thorough Your research design should demonstrate that you
are a competent researcher who is knowledgeable about the proposed research
methodology or methodologies Therefore be sure that you carefully describe
and give technical explanations for each component of your research
B5 Choose a specific situation involving employee selection eg artists for an
advertising agency (a) What strategy would you use in selecting the selection
measures (b) How would you combine the measures eg which measures
would you combine in a compensatory manner and which is a noncompensatory
manner (c) How would you assume test fairness defining various measures of
the term (d) How would you make final selections (e) How would you
validate your procedure (f) What considerations would enter in if your
company were too small to provide validation data (g) What difference would
it make if you were developing a procedure for deciding whether trainees
should be promoted as opposed to making new hires Please note--emphasize
but do not limit yourself to statistical issues
B6 There is evidence in the marketing literature of a non-monotonic relationship
between the expectations that customers have for retail service and their
eventual level of satisfaction with that service That is as a customers
expectations for service increase so does their eventual service satisfaction --
up to a point After that point the greater the expectations the lower the
eventual satisfaction Develop a hypothesis that includes a moderator variable
that might account for this evidence Give some reasonable rationale for it State
your hypothesis verbally as an equation as a directed graph (circle amp arrow
diagram) and as an X-Y function chart Discuss how it would or would not be
possible or useful to test your hypothesis via a laboratory experiment In your
discussion cover how and why a researcher could (not) manipulate the
independent constructs involved (mode X) whether or not random assignment
to conditions (mode R) is possible (including how may conditions would be
necessary) which alternative constructs could or could not be controlled (mode
K) and which constructs should be measured (mode Y)
B7 Assume you are the chairperson of a committee that must evaluate
undergraduate programs at your university Your task as chairperson is to
devise an approach (a design a research strategy a set of measures) that will
allow you to evaluate undergraduate programs Make sure that your approach
can be used in the future and at other comparable universities When developing
your plan be sure to address at least the following issues
a the type of design you would select Compare and contrast the selected design
with another possible design
b the type of research strategy you would select Compare and contrast with
another possible strategies
c discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
B8 Assume you are an organizational research design expert assigned to the
Strategic Planning Department of a large multi-national manufacturing firm
The Department has developed a new PC-based software package called
STRATPACK The software (and a one-week training course to learn how to
use it) is intended to improve the long-range planning ability of middle and
upper-level managers
Your job as research design expert is to devise research (a design a research
strategy a set of measures) that will allow you to evaluate the effectiveness of
the STRATPACK program Describe a research design for evaluating the
program Make sure that your research approach can be used in the future and at
all sites in the company When developing your plan be sure to address at least
the following issues
a discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
b the type of design you would select (eg a design where you manipulate the
independent variable versus observe the independent variable) Compare and
contrast the selected design with another possible design
c how your design deals with the major forms of validity Be sure to examine at
least internal external and construct validity
B9 Assume you are a consultant hired to evaluate the effectiveness of an industrial
safety program undertaken by a large manufacturing organization The safety
program is a behavioral one that provides rewards such as monetary bonuses or
extra paid vacation days for safety behaviors in terms of accident-free days
weeks etc Your task is to devise an approach (a research strategy a design a
set of measures and a general analysis strategy) that will allow you to evaluate
the safety program Because of the potential for the influence of many
extraneous variables on any safety program it is difficult to design research a
single cross-sectional study than can evaluate the impact of a single safety
program How would you design a study to evaluate the impact of the safety
program When developing your plan be sure to address at least the following
issues
a the type of research strategy you would select Compare and contrast with
another possible strategies
b the type of design you would select Compare and contrast the selected design
with another possible design
c discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
B10 One of the most important areas of research is forecasting of human resources
needs based on strategic positions of organizations For example NY State must
carefully forecast its human resources needs as it proceeds with significant lay-
offs of state employees Future human resources needs are generally evaluated
by either statistical ie regression or simulation or clinical judgment i e
supervisors judgments methods
a Design a single study that addresses the empirical question of whether
statistical or judgmental methods are better for forecasting human resources
needs You may discuss a program of research but please be quite specific in
your description of the first study
b What are the critical methodological issues in doing this kind of research
c What are the critical applied (or practical) issues in doing this research
d Are the issues in b and c related
B11 In the past decade computinginformation technology has changed many
aspects of organizational life For example the technology can make increased
decentralization possible by improving communication between central offices
and field offices Computer networks and word processors can enhance group
empowerment by making it possible for team members to create and edit
written group products quickly even if the individuals are at different locations
Some have argued that computinginformation technology will foster the
paperless productive office nevertheless others argue that the technology only
increases paper and reduces office productivity You are applying to the
National Science Foundation for a grant to conduct research that examines the
impact of computing information technology on organizational decision
processes The NSF application procedure imposes five basic requirements that
your research design must fulfill in order to receive funding Note A very
significant factor affecting NSF grant decisions is a clear demonstration that the
researcher is knowledgeable about the research methodology used Write your
response to each of the following five grant requirements Be sure not only to
respond to the requirement but also to demonstrate your research
competence
1You must design a study that uses two different methods
(interviewobservation survey experiment or quasi-experiment) Describe your
two methods in detail and provide a rationale for the key elements (eg
sampling data collection proposed analysis) of your methods Be sure to
discuss and evaluate the internal and external validity of both methods
2 As part of your research design you must select a conceptual (latent) variable
central to your proposal (use centralization of decision making as your
variable) and describe how you will develop your own measure (You may not
simply use off the shelf instruments)
3 You must describe how you will test for the reliability of the measure
(centralization of decision making) you developed in step 2 The NSF insists
that you describe how you will evaluate both the temporal stability and the
internal consistency of your measure Be sure to discuss what temporal stability
and internal reliability mean and how they are related
4You must describe how you will assess the validity of the measure
(centralization of decision making) you developed in step 2
5 NSF requires a brief statement and defense of the philosophy of science
underlying your research Discuss your position and show how your research
design is consistent with your philosophy
B12 Many organizations in the United States economy have installed some form of
Empowered Teams as an alternative or supplement to traditional bureaucratic
structure Preliminary evidence of the effectiveness of empowered teams
however is mixed--some organizations have claimed success and others have
reported failures The evidence however is predominantly anecdotal--written
for trade magazines by the organizations themselves There are few rigorous
empirical studies assessing the effectiveness of empowered or self-managed
teams You are applying to the United States Department of Labor (USDOL) for
a grant to conduct research that examines the effectiveness of empowered
teams The application procedure of the USDOL imposes three requirements
that your research design must fulfill in order to receive funding Write your
response to each of the three grant requirements The importance of each section
is implied by the evaluation points allocated by the USDOL to each of the three
requirements given in parentheses
1 (50 points) Your study design for assessing Empowered Team effectiveness
must use two different methods (interview observation archival analysis
survey simulation experiment or quasi-experiment) Describe in detail and
thoroughly explain the sampling plan instrumentation data collection
procedures and proposed data analyses for both methods Be sure to discuss the
internal and external validity of both methods and how the two methods
complement one another
2 (30 points) As part of your research design you must select one conceptual
(latent) variable central to your proposal and describe how you will develop
your own operationalization of the measure (You may not simply use off the
shelf instruments) Use the concept of group morale to demonstrate your
operationalization methodology Be sure to explain very explicitly to the
USDOL how you will assess the validity and reliability of the group morale
measure you are developing
3 (20 points) The USDOL traditionally has funded research conducted only
within the general paradigm of logical positivism but now is more open to other
research paradigms as well Your grant proposal must provide a statement and
defense of the explicit philosophy of science underlying your research Describe
your philosophy of science and show how your research design is consistent
with your philosophy
REMEMBER Be thorough You not only must design effective research but
you also must demonstrate to the USDOL that you are a competent researcher
It is absolutely vital to the USDOL that the principal researcher is
knowledgeable about the proposed research methodologies Therefore be sure
that you always carefully describe and give technical explanations for each
component of your research design and explain all technical terms (eg
Cronbach alpha KR-20 Likert scale)
B13 Assume that you are working as part of a research team that is responding to a
RFP (Request for Proposals) from a funding agency for research on work
socialization and newcomer adjustment The RFP calls for rigorous field
research that tests the effectiveness of theory-based interventions aimed at
facilitating the adjustment of new organizational members to complex andor
stressful work conditions The major goal of your teams research is to test the
effectiveness of a self-regulation intervention which trains newcomers to
identify and use relevant social information and cues to regulate work behavior
Your group hypothesizes that self-regulation training will be more effective
than other common treatments or interventions (eg realistic job previews
institutionalized socialization tactics)
You have been included in the team because of your methodological expertise
Your role is to design a rigorous field experiment or quasi-experiment to test he
effectiveness of the self-regulation training program REMEMBER THE
MAJOR CRITERION FOR FUNDING IS THE RIGOR OF THE RESEARCH
DESIGN Design a field study to include in the grant proposal Your proposal
should contain the following two sections
1 Study Design Construct and describe in detail an experimental or quasi-
experimental design to test the effectiveness of your intervention Describe in
detail the experimental groups (including how they will be constructed) the
research setting the sampling plan for study participants the treatment
manipulation and the data collection procedures Also indicate any control or
nuisance variables that may be measured
After describing the procedures write a justification of the design What threats
to validity does it rule out or limit and what threats to validity remain
II Measurement Describe the steps you would take to achieve valid and
reliable measure of the latent (conceptual) variable worker adjustment Your
team feels that as part of the proposal you must develop an original
operationalization of adjustment (thus you cannot simply use existing off the
shelf measures) Indicate in adequate detail how you would operationalize the
measure and indicate how you would demonstrate reliability and validity
B14 In describing their notion of the collective mind Karl E Weick and Karlene H
Roberts note Our focus is at once on individuals and the collective since only
individuals can contribute to a collective mind but a collective mind is distinct
from an individual because it inheres in the pattern of interrelated activities
among many people (p 360) Collective mind is not indexed by within-group
similarity of attitudes ideas or activities A collective mind is one in which
many people or many groups integrate their different attitudes ideas and
activities heedfully As Weick and Roberts note People act heedfully when
they act more or less carefully critically consistently purposefully attentively
studiously vigilantly conscientiously pertinaciously (p 361)
The idea of the collective mind as heedful interrelating is developed in the
following excerpt When people make efforts to interrelate these efforts can
range from heedful to heedless The more heed reflected in a pattern of
interrelations the more developed the collective mind and the greater the
capability to comprehend unexpected events that evolve rapidly in unexpected
ways When we say that a collective mind comprehends unexpected events we
mean that heedful interrelating connects sufficient know-how to meet situational
demands For organizations concerned with reliability those developments
often consist of unexpected non-sequential interaction (p366)
An example of heedful interrelating occurs as a pilot lands herhis aircraft on the
deck of an aircraft carrier The pilot does not actually land She is recovered
A recovery is an interrelated set of activities among air traffic controllers
landing signal officers the control tower navigators deck hands the helmsman
driving the ship etc These activities can be interrelated more or less heedfully
depending on the care with which the different units contribute represent the
situation and subordinate their activities to the single purpose of successful
recovery (p 363)
You are to design a two-part study
Part I You are to design a measurement study which assesses heedful
interrelating (ie collective mind) with a quantitative measure in a replication
of an aircraft carrier flight deck or other situation of your choosing Describe
your research strategies including operationalization of the variable selection of
the sample subjects data collection data analysis and so on for the purpose of
developing a measure of heedful interrelating
Part II Using the measurement tool developed in Part I and any other tools as
needed describe how you would design a study which would compare heedful
interrelating across organizations Choose at least one macro-organizational
variable (eg technology environment) as your basis of comparison Here you
must describe how you would make your selection of organizations to be
compared your data collection procedure data analysis and so on
B15 Many organizations in the United States have installed cross-functional teams to
counteract the silo mentality of traditional bureaucratic structure Preliminary
evidence of the effectiveness of cross-functional teams however is mixed --
some organizations have claimed success and others have reported failures The
evidence moreover is predominantly anecdotal--written for trade magazines by
the organizations themselves Since there have been few rigorous empirical
field studies assessing the effectiveness of cross functional teams the National
Science Foundation has decided to fund research on the topic
Assume that you are submitting a research proposal to NSF for a grant to
research the effectiveness of cross-functional teams Describe in detail and
thoroughly explain the research design sampling plan data collection
procedures ethical issues and proposed data analysis for your research design
Be sure to discuss the internal and external validity of your research Which
validity threats are ruled out and which remain NSF also requires that you
provide a statement and defense of the explicit philosophy of science underlying
your research Describe your philosophy of science and discuss how your
research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but
you must also demonstrate to NSF that you are a competent researcher It is
absolutely vital to NSF that the principal researcher (you) is knowledgeable
about the proposed research methodologies Therefore be sure that you always
carefully describe and give technical explanations for each component of your
research design and explain all technical terms (eg Cronbach alpha KR-20
Likert scale)
B16 Assume that you are submitting a research proposal to the Department of
Commerce (DoC) for a grant to research the effectiveness of virtual work teams
A virtual work team is a leaderless collection of individuals who are
geographically separate from one another and share their expertise using
internet media such as a listserver or Lotus notes The DoC requires that the
researcher use both qualitative and quantitative methods to gather data Describe
in detail and thoroughly explain the research design sampling plan data
collection procedures ethical issues and proposed data analysis for your
research design Be sure to discuss the internal and external validity of your
research Which validity threats are ruled out and which remain The DoC also
requires that you provide a statement and defense of the explicit philosophy of
science underlying your research Describe your philosophy of science and
discuss how your research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but
you must also demonstrate to DoC that you are a competent researcher It is
absolutely vital to DoC that the principal investigator (you) is knowledgeable
about the proposed research methodologies Therefore be sure that you always
carefully describe and give technical explanations for each component of your
research

5 MEASUREMENT
A) Measurement Terms
A1 There are four levels of measurement rigor in management research Discuss each
one What properties do measurements at each level have (ie how much
information do the numbers from each level of measurement convey) How can the
numbers be changed (transformed) and still retain the properties of their
measurement level Pick one construct from a favorite research domain and give an
example of an operationalization of that construct at each of the four levels of
measurement rigor (provide arguments about why you think those examples reflect
each level) Lastly treat each examplelevel as a dependent variable in some
statistical analysis Given an example of a statistical technique appropriate for
analyzing data at that level of measurement rigor
A2 Define (and discuss important features or issues concerning) the following
constructs measurement (Define any six terms)
1 Construct validity 6 Item analysis
2 Likert scaling 7 Semantic differential
3 Cronbachs alpha 8 True score
4 Unobtrusive (trace) measurement 9 Generalizability theory
5 Interval scale 10 Criterion-related validity
11 Sociometric choice measures
B) Operationalization
B1 a) You are conducting a study which requires you to measure Hong Kong real
estate agents self-assessment of performance Since there is no existing
measurement available you have to develop the instrument by yourself
Describe how you would develop the measurement assuming that you have no
idea of how many dimension the construct has
b) Suppose you have developed an instrument consists of 20 questions
measuring 4 dimensions (5 items per dimension) from (a) You collected data
from another 300 real estate agents to validate your instrument Explain how
TH
you would use structural equations model (SEM) to examine the reliability and
validity of the instrument What are other concerns about reliability and validity
that are not addressed by this approach
B2 The research and business world have been fascinated with the concept of
organizational culture However operationalizing this construct has been a
difficult task Discuss the ways in which the construct has been operationalized
(eg technique static v dynamic sample selection generalizability) Critically
analyze each of these methodologies Then choose a methodology you would
use to examine organizational culture and defend your choice Describe how
you would study culture and what more would be known about culture as a
result of your study
B3 Suppose you are setting out to develop a new measure of a construct You want
this measure to be used in survey research and you want to establish its validity
and reliability Your goal is to have at the end of the process a measure that is
defensible and likely to be widely accepted by other researchers studying that
construct What steps would you take to conduct such a program of research
For each step explain the purpose of that step explain why that step is
important explain what methods and statistical procedures you would employ at
each step and explain what evidence you would hope to gather at each step
B4 Assume you are interested in constructing a new measure of (fill in with a
relevant variable from your field) Detail the major concerns that need to be
addressed and the steps that need to be taken in working toward validating this
new measure
B5 Assume that you recently read an article on workplace violence which you
found very interesting The authors argued that one of the predictors of
workplace violence was a construct called propensity to be violent and used a
one-item measure as follows How likely are you to become violent when
provoked You had serious doubts about the authors measure and decided to
develop your own
(a) How would you go about developing items to measure propensity to be
violent
(b) How would you determine whether the instrument was reliable
How would you determine whether the instrument was valid
B6 A concern in organizations is retirement of baby boomers within the next 5 -
10 years This concern is focused on the loss of older employees with skills
critical to the core business functions of organizations In order to continue to
have employees with those critical skills it seems necessary to retrain some
older workers However past practice in most organizations has been not to
retrain older workers for a variety of reasons mostly financial A researcher
working for the Human Resources Department of a large corporation - 13500
employees in 12 different plant locations - hypothesizes that the major reason
for not retraining older workers is ingrained in the culture of the corporation
IC
The researcher feels that older workers are not as highly valued as younger
workers in terms of their potential usefulness after retraining The researcher
searched the literature but found nothing in the existing literature to measure
the cultural value construct What should the researcher do to establish a reliable
and valid self-administered paper and pencil measure of this construct namely
the value of retraining older workers
a Please describe and explain the steps in temporal order that the researcher
must follow to develop a measure
b How would you evaluate the measure based on the technical requirements of
reliable and valid measurement as well as any practical issues in using the
measure considering the size of the employee population
B7 Assume that you are going to conduct empirical research to assess the role that
the complexity of an organizations manufacturing technology plays in
determining the level of centrality of decision making in the organization
Describe and justify the steps you might follow to develop an operationalization
of the concept of technological complexity What standards would you use to
determine if your operationalization is valid
B8 Organizational researchers have several strategies available to them for
gathering information (eg self-report measures archival measures direct
observation and trace measures) Assume that you are going to conduct
empirical research to assess the role that the structure of the organization plays
in determining the level of organizational effectiveness Briefly review the
strengths and weaknesses of the basic strategies (that is self-report measures
archival measures direct observation and trace measures) for measuring
organizational effectiveness Next describe and justify the steps you would
take to develop an operationalization of the concept of organizational
effectiveness What standards and procedures would you use to determine if
your operationalization is valid
B9 One of the most important topics of recent research has been stress in the work
place One of the most important problems with understanding this literature is
the varying definitions and measurement of this construct Suppose you had
decided to investigate the relationship between stress at the work place and dual
career family happiness
a Since there are multiple ways to measure stress in the work place describe
two ways to do this Hint - avoid using two self-report measures
b Describe how you would decide on the best single measure In doing so
describe the steps you would take in evaluating your measure Be sure to define
your meaning of validity and reliability It is important that your measure have
all the necessary psychometric characteristics so that other scientist can trust the
results of your research
c Be certain that you answer the question Validity for what
d In order to understand the results of your study you need to compare your
measure of stress at work with other measures of this construct How would you
do that
B10 Assume that you have been hired by a national survey research company
Shash Inc to write items that will be used in a national survey of attitudes
toward capital punishment There are a number of criteria that can be used to
guide your item writing What are they Briefly describe five (5) such criteria
B11 Assume that you are going to conduct empirical research to determine the
impact of interpersonal trust on organizational decision making Describe and
justify the steps you might follow to develop an operationalization of the
interpersonal trust concept
B12 Assume that you are going to conduct empirical field research to assess the role
that employee empowerment plays in determining the level of organizational
commitment of employees Describe and justifyexplain the steps you would
follow to develop a valid and reliable operationalization of the concept of
employee empowerment
Explain the procedures and standards you would use to determine if your
operationalization is valid and reliable
How would you assess the construct validity of such a measure
Discuss issues concerning the level of observation of your measure and level of
analysis of the data
B13 Assume you are interested in developing a new scale to measure construct X
Further assume that you have used previous literature and your own conceptual
development to delineate 2 dimensions of X specifically XF1 and XF2
Describe the steps you would go through in developing testing and evaluating
this new scale With regard to testing and evaluating be sure to consider the
role of factor analysis (both exploratory and confirmatory) and item analysis
Also you will want to make sure that your new multidimensional scale shows
evidence of validity (several kinds) and reliability so be sure to examine these
issues and explain how specific information gathered from the above testing
contributes to these concerns
C) Reliability
4) What is reliability and why is it so important What are the different ways reliability can be
assessed and when is each appropriate
15) What does coefficient alpha assess What are the ways coefficient alpha can be increased
C1 Describe and discuss the concept of reliability and all of its various forms
including their assessment When is each form appropriate and what information
is provided by each index
C2 In establishing congruence between multiple measurements we often compute
indices of reliability andor indices of agreement These two types of indices
address very different questions Your task is to 1) Define reliability and
agreement 2) Explain when each is useful using examples in which one but not
the other is appropriate and 3) Briefly describe two reliability indices and two
agreement indices
C3 Explain reliability in terms of the classical test theory What are the
consequences of unreliable measures in hypothesis testing What are the factors
that may affect the reliability of a multi-item scale
IC
C4 Generalizability theory is used within IO psychology more often today
However most researchers continue to use Classical Test Theory
conceptualizations of error to determine reliability What are the implications of
using classical test theory versus generalizability theory to assess reliability
C5 In establishing congruence between measurements we often compute indices of
reliability andor agreement Define reliability and agreement Explain the
differences in reliability and agreement and describe under what conditions
assessing reliability is more appropriate and under what conditions assessing
agreement is more appropriate
C6 Define measurement reliability in terms of a specific measurement theory (eg
true test score theory domain sampling theory generalizability theory IRT)
Discuss the different approaches for estimating reliability and the contexts in
which each might be appropriate Use examples throughout
C7 What are the consequences of unreliability in a measure
C8 What are some of the conditions that might keep the internal consistency (eg
alpha) of a given measure low Is a low alpha always a sign of a problematic
measure
C9 Define reliability Name some methods of calculating reliability How well do
these methods map up with the definition of reliability What is the impact of the
number of test items and sample size on Chronbachs alpha and why would this
effect occur or not occur (Note Do NOT discuss inter-rater reliability)
C10 Schmidt and Hunter (1996) described several types of measures typically used in
organizational research and identified the type(s) of measurement error affecting
each of them in various situations For each measure below indicate the types of
error and sources of error that are most likely to affect it Then indicate what
could be done to reduce errors of measurement andor what can be done to
control for errors statistically
a Supervisor ratings of subordinates job performance
b Self-ratings of ones own job performance
c Self-reports of ones own job-related attitudes
d Sales figures for a salesperson (or production quantity for a production
worker)
d Aptitude tests taken as part of the hiring process
C11 Suppose you had conducted research on the relationship between organizational
commitment and rigidity of organizational structure in 200 firms Your measure
of rigidity was based on number of organizational authority levels and the degree
to which written organizational rules existed and defined role behaviors for
employees Thus an organization with a large number of organizational levels
and specific written policies defining appropriate role behaviors for employees
would score high on rigidity of organizational structure After analyzing your
data you find that there is a statistically significant negative correlation between
commitment and rigidity which is consistent with your hypothesis However the
reliabilities for your two measures are
(1) commitment = 23 (2) rigidity = 83
How should you interpret your results What could you do to fix this situation
Describe the specific steps (in order) you would follow to develop a more
reliable measure of commitment
C12 (a) Define the concept of reliability (of measures) in a clear concise and
accurate manner (b) Provide a formula that expresses the reliability of a measure
in terms of two components of variance ie total variance and the error
variance
D) Multi-level Assessment
D1 One of the major challenges for group-level research is the issue of aggregation of
individual data to the group level
(a) Under what conditions (eg types of data number of raters) should the various
interrater agreement and reliability methods be used (Rwg Kappa and Weighted
Kappa percent agreement average pairwise correlation ANOVA methods
(interclass correlation coefficient WABA)) What are the advantages and
disadvantages of each of the methods
(b) Explain the controversy between Frank Schmidt Larry James and others
regarding the differences between interrater agreement and interrater reliability
Who is right Do the differences matter in research practice
Defend your answers
(c) Review two articles from the organizational behavior literature that have had to
deal with aggregation issues Critique the methods the authors used to make
aggregation decisions
(d) Provide some advice to researchers regarding what they should do if interrater
agreement and reliability indices indicate that it is not legitimate to aggregate their
data
(e) Provide some ideas for avoiding the need to aggregate in group-level research
through creative research methods and measurement strategies
D2 Cross-levelmulti-level research is becoming more evident in the organizational
research literature This type of research raises many issues and presents many
challenges in terms of designing the research measuring variables and collecting
and analyzing the data Assume that you are interested in aggregating data (eg
from the individual to the group or from the firm to the industry) for one or more
variables What are the major issues you will need to deal with
D3 A researcher wants to measure organizational climate for continuous learning
Organizational climate is operationalized as a shared consensual aspect of the
organization -- the shared perception among employees that the organization values
and supports continuous learning Describe how you would measure organizational
climate in this case Specify (a) the level (ie individual group organization) at
which the construct exists (b) the level at which you would measure the construct
and (c) the procedures that you would use to establish that measurement is aligned
with theory (ie the construct validity of the measure)
E) General (Measurement)
E1 Studies in organizational behavior research often rely on single-item measures of
key constructs The use of single-item measures has long been criticized based
on the premise that single-item measures are unreliable However Wanous
(Wanous amp Hudy 2001 Wanous amp Reichers 1996 Wanous Reichers amp Hudy
1997) has recently argued that single-item measures can exhibit adequate
reliability Wanous based this conclusion on a procedure for estimating the
reliability of single-item measures using the classic formula for correction for
attenuation Subsequent studies have yielded mixed results regarding the
conclusions of Wanous (eg Loo amp Kells 1998 Nagy 2002) and the veracity
of the perspective advocated by Wanous remains in question Summarize and
assess the arguments for and against the use of single-item measures and
evaluate the procedure and evidence offered by Wanous regarding the reliability
of single-item measures Based on your assessment and evaluation develop
recommendations regarding the use of single-item measures in organizational
behavior research

E2 Ipsative measures have become prevalent in organizational behavior research
Ipsative measures ask respondents to answer questions relative to one another
such that the scores for all questions sum to the same constant for all respondents
Examples of ipsative measures include rankings Q-sorts and the allocation of a
fixed number of points (eg 100) across a set of response options Ipsative
measures may be contrasted with absolute measures which ask respondents to
answer questions independently from one another Absolute measures are
exemplified by rating scales using an interval or ratio numeric response format
The relative merits of ipsative and absolute measures have been debated for
decades (eg Cornwell amp Dunlap 1994 Hicks 1970 Johnson Wood amp
Blinkhorn 1988 Saville amp Wilson 1991 1992) yet the fundamental issues
underlying this debate have not been adequately addressed in organizational
behavior research For example measures of organizational culture and values
are often ipsative and some researchers advocate these measures over absolute
measures (eg Meglino amp Ravlin 1987 OReilly Chatman amp Caldwell 1991
Ravlin amp Meglino 1987 see also Rokeach amp Ball-Rokeach 1989) Review the
relative merits of absolute and ipsative measures Based on your review which
form of measurement is most appropriate and why Do your conclusions depend
on the construct being measured If so what types of constructs are best suited to
ipsative measures and what types are best suited to absolute measures Next
apply your conclusions to the measurement of culture and values in
organizations What specific arguments have been advanced in favor of ipsative
measures of culture and values How sound are these arguments Should ipsative
measures be used in the study of organizational culture and values If not how
can absolute measures of culture and values be developed that address the
concerns voiced by advocates of ipsative measures Provide a specific example
of the type of measure you would propose

facets of a concept Although such measures are prevalent and in some cases are
advocated (eg Law et al 1998 1999) they can present a variety of conceptual
and methodological problems Describe the specific problems associated with
measures that use items representing different facets of a concept Compare these
problems with the purported advantages of such measures Conclude by

E5 Suppose Roberta Von Eisenbrick is a researcher interested in the consequences of
AFFECTIVE CONFLICT (AC) in decision-making teams She gets access to a
variety of outcomes assessment committees at each of 87 different schools in
the Dallas Independent School District and gains permission to tape-record two
of their meetings (one in February and one in March) Such committees have
been formed to develop quantitative ways to track pursuit of school goals and
provide accountability to local and state governments These are often divisive
teams with heated meetings because what gets assessed is what usually gets
rewarded After both of these meetings the committee members each
fill out a short questionnaire that contains 20 Likert-type items measuring how
much AC occurred (eg People in our group often get angry with each other)
The individual scores are summed across items then averaged across team
members to come up with a group-level AC score for each of the 87 2
meetings The same procedures are followed for a 5-item measure of Group
Cohesiveness (GC) which is predicted to be reduced by higher levels of AC
Roberta also listens to every tape and from her expert judgment she rates each
groups meetings on the same 20 items Those 20 ratings are summed for each of
the 87 2 meetings Now Roberta is interested in evaluating her measure She
wants it to have excellent psychometric properties including reliability and
construct validity

least three kinds of estimates and the sources of error each one assumes or is
estimating Pick one of those kinds of estimates and provide a rationale for using
it
c What is construct validity Discuss how the (un)reliability of the AC measure
could affect the conclusions one would draw from a study involving it and GC In
your discussion be sure to go over the connection between reliability and
validity and the connection between reliability and the probability of Type I or
Type II statistical errors

are the essential elements of these critiques What are some remedies to the
problems engendered by significance testing and why have these remedies not
been widely adopted

D) ModeratorsMediators
D1 Moderation and mediation provide different ways to model third variable effects
(a) Please define both of these terms (b) Sketch a conceptual model to show how
each relates to main effects (c) Using variables of your choice please write
hypotheses to reflect both (d) Explain how each is tested analytically
D2 Discuss moderators and mediators Provide an example of how (1) a moderating
variable influences the relationship between the independent and dependent
variable and how (2) a mediating variable influences the relationship between
the independent and dependent variable Describe how you would test for both
moderation and mediation using regression
D3 Many theories in organizational research predict that the effects of one variable
on another are moderated by a third variable Such moderator effects are
typically tested by entering the product of two variables as a predictor after
controlling for the two variables that constitute the product Several researchers
have pointed out that this product is often highly correlated with the squares of
the two constituent variables and have suggested that moderating effects may be
tested after controlling not only for the two constituent variables but also their
squares (eg Cortina 1993 Ganzach 1998 Lubinski amp Humphreys 1990
MacCallum amp Mar 1995) Discuss the strengths and weaknesses of this
approach as compared to methods that use only the product term and its
constituent variables Conclude with recommendations as to when and under
what conditions organizational researchers should test moderator effects with the
squares of the constituent variables in the equation

D4 Assume you are interested in studying relationships amongst three variables X
Y and Z Your first hypothesis posits Z as a mediator of the relationship between
X and Y Your second hypothesis posits Z as a moderator of the relationship
between X and Y Draw the figures depicting each of these hypothesized
relationships and describe (make sure to write regression equations) how you
would test each of these hypotheses
D5 The amount of time and effort that the average person pours into his or her job
has risen steadily over the last two decades such that the average person now is
working one more week per year than the average person in the mid 1970s This
steady increase has fueled research interest in the construct of Job Burnout (JB)
which is an emotional and physical exhaustion associated with ones work
Organizational Stress (OS) the perception of greater demands than available
resources in ones work environment is thought to be one of the chief
antecedents of JB However time spent under OS is thought to make its affects
on JB accumulate or worsen Work Role Withdrawal (WRW) the avoidance of
responsibilities or the deliberate reduction of inputs to ones job is believed to be
the chief consequence of JB
a Formally state these ideas as verbal hypotheses as equations and as a complex
directed graph (circle amp arrow diagram)
b Conceptually what is a mediator Define the term and identify the mediator in
your hypotheses in (a) What elements or steps in a study design (not statistics)
that would be helpful for detecting the mediating relationship that was proposed

subdomains of management Further demonstrate your understanding of
moderator variables by picking which variable in (a) is the moderator Show the
moderating relationship in an X-Y (or multi-layered) chart Again what elements
or steps in a study design (not statistics) would be helpful for detecting the
moderating effect implied above

recommendations You conduct a well-designed controlled study (details are unimportant) and discover students who use the new book perform 10 better on a standardized subject
matter exam than those using the old book (p = 027) Both books are readily availabe their prices are almost identical and both are equally acceptable to the instructors What is your recommendation to the chair
F1 Attached is the beginning of an article Your task is to write the results section by
1 making up and reporting plausible descriptive statistics that will help the
reader understand the results of the statistical tests you report and the nature of your
sample (Hint this can be presented in the form of a table)
2 describing and defending your choice of appropriate statistical tests of the
hypotheses and the steps that you would go through in carrying out these tests
3 making up and reporting results of these tests that are consistent with your
descriptive statistics and with any information in the rest of the article about the
results found (Hint this can be presented in the form of a table)
4 describing how well these results provide support for the hypotheses You
may want to note any relevant threats to validity here
Be sure to state any assumptions you make
F2 Assume that the Personnel Manager of a local firm Ms B dFlandres hired you to
analyze some data that her assistants had collected over the past several years The
data consist of (a) job performance ratings that were made in June of 1990 and (b)
scores on 25 predictor variables (eg measures of education job experience job
tenure job aptitude personality) that were measured when the individuals were hired
(between April 1987 and May 1988) She had data from only the 110 subjects (60
males and 50 females) who were hired during the period and were still employed by
the firm One objective of your analysis (analyses) is to determine how well the
performance criterion can be predicted by the predictors What strategy would you
use in analyzing the data Describeexplain (b) Is sample size an issue for your
analyses Explain If it is what will you do to deal with problems stemming from
sample size Assume that no additional data can be collected at this time (c) Some
preliminary analyses that you do reveal that five of the predictor variables correlate
(zero-order basis) about 75 with one another Will this influence the analyses that
you use Will it influence the validity of conclusions derived from your proposed
analyses (d) Ms dFlandres is interested in knowing if the predictor variables are
equally effective in predicting the job success of males and females What analysis
or analyses would you do to deal with this issue
F3 Assume that you have been provided with data on 12 conceptually distinct variables
that are moderately correlated with one another at the empirical level The data are
from students in four different college majors ie astronomy (A) biology (B)
criminology (C) and demography (D) The 12 measured variables fall into the
general categories of mental health (tension emotional withdrawal hallucinations
guilt feelings blunted affect and suspiciousness) and job satisfaction (work itself
supervision co-workers pay promotion prospects and working conditions) Your
task is to determine if the individuals in the four college majors differ from one
another on the 12 measured variables
(a) What statistical technique(s) would you use to test for group differences
Explain Be specific about the procedures(s) that you would use
(b) What statistical estimate would you use to estimate the extent to which the
groups differ from one another Be specific
F4 The following statistical table published in a recent issue of Work amp Occupations
was taken from an article discussing variables influencing resistance and citizenship
behaviors in the workplace Resistance behaviors include playing dumb withholding
effort work avoidance subverting particular managers and sabotage Citizenship
behaviors include cooperation engaging in peer training use of insider knowledge to
facilitate production commitment to organizational goals giving extra effort freely
Both measures are global constructs aggregated to the interval level and
standardized
The table reports the results of a series of ordinary least squares regression equations
with standardized coefficients Explain the meaning of the statistics presented What
do these statistics tell us generally about the relationship between resistance
behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows
Anomie Index -standardized interval level measure tapping multiple dimensions
The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)
F5 Researchers collected data from a sample of 350 companies on the following
variables
size (measured as number of employees)
Business Strategy (a nominal variable with 2 response options low-cost provider or
differentiator)
HR Strategy (a nominal variable with 2 response categories High commitment or
low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

exploratory way Also describe the difference in principal components analysis
(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression

advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss

parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)
Please comment on these restrictions versus access argument Which side do you
take

A10 In recent years there has been considerable debate in the social and behavioral
sciences concerning two competing research paradigms--one based on a logical
empiricismrealist epistemology and the second based on a post-empiricist
epistemology These paradigms vary with respect to their underlying aims
(goals) standards for judging explanations and ontology
a Describe the basic aims standards and ontology for each paradigm What
characteristics distinguish these two paradigms
b One current concern focuses on the appropriateness of a priori and post-hoc
explanations for theory testing Describe and defend your point-of-view
concerning which type of explanation is appropriate for research in
organizational studies
c A second current concern focuses on the appropriate treatment of the
independent variables that is an experimental approach (where the independent
variables are manipulated) and an observational approach (where the
independent variables are observed) Describe and defend your point-of-view
concerning which treatment of the independent variables is likely to produce the
more important contribution to organizational studies
A11 What rules of evidence are used by the positivist research paradigm to determine
whether a research finding is meaningful Choose another research
philosophyparadigm and compare and contrast it to the positivist rules of
evidence
A12 A major tenet of research is that research subjects should have limited if any
knowledge of the subject of the research The assumption is that subjects will
not act naturally if they are aware of the purpose of the research For this reason
researchers often engage in various types of deception For example
experimental and survey researchers will word instructions in such a way as to
hide the research goals and researchers who conduct participant observation
will avoid telling people they are researchers Discuss the ethical questions
raised with deception What guidelines would you give to a colleague who was
conducting research that involved deception
B) Causation
1) Explain the phrase ldquocorrelation does not equal causationrdquo Why is the distinction so
important What conditions must be met to establish causation Can they ever be
completely satisfied
12) Why is a posttest only design without random assignment to treatment conditions
uninterpretable from a causal standpoint
B1 Choose a model from the Organizational Behavior literature that has causal
orderings between variables and has been tested in a field setting Compare the
following data analytic methods for testing hypotheses about causality between
variable sets (eg dependent independent intervening moderating exogenous
endogenous)
a) path analysis using hierarchical regression
b) maximum likelihood estimates of structural equations models (perhaps through
LISREL)
Your answer should address
1 The parameters the procedures estimate and how they are estimated
2 How the validity of the models are judged
3 Appropriate inferences of causality and conditions necessary to make such
inferences
4 The statistical assumptions underlying each technique and the consequences of
violating assumptions
B2 Describe the critical-realist perspective of Cook and Campbell (1979) Compare and
contrast this perspective on causality with that of Poppers falsificationism
B3 According to Cook and Campbell (1979) causal relationships in the social sciences
can be probabilistic and still meet the assumption of causality that asserts that a
cause must always produce an effect Describe the logic they invoke to justify this
position
B4 Identify James Mulaik amp Bretts (1982) conditions for establishing causal
inference Discuss what they mean and why they are important to causal inference
B5 What are the three conditions necessary to establish causality Can these conditions
ever be fully met Why or why not
B6 Assume you are interested in conducting a study that allows you to legitimately
make some causal inferences concerning relationships among a set of constructs
What sorts of things can you as the researcher do to bolster your ability to make
such causal inferences In answering this question be sure to pay attention to issues
pertaining to both study design and data analysis
B7 Some researchers (and editorsreviewers) are very critical about the ease with which
others use causal language in interpreting their analyses What are the concerns
behind this criticism and what are the methodological and statistical conditions that
give rise to these concerns Under what conditions can researcher make reasonable
valid causal interpretations of their findings Can a researcher ever be completely
confident making such causal statements Be sure to defend your position in
answering these questions
C) Theory amp Research
C1 What are the elements of a theory What criteria did Bacharach (1989) use to
evaluate if a theory is good
IC
C2 The Academy of Management Journal in its Information for Contributors
states All articles published in the Journal must make a strong theoretical
contribution Because this is one of our top publications we must have a clear
understanding of what constitutes a strong theory Describe the essential elements
of a good theory You can also describe practices that are not indicative of good
theory if that will help you articulate what is good theory
C3 Organizational researchers place a high premium on research that is guided by
theory This perspective is evident in journals such as AMJ and ASQ which will
often reject a manuscript that describes a sound empirical study but does not
provide a theoretical contribution Is there a role for atheoretical research in the
organizational sciences If so what is the role of atheoretical research and what
contribution does it make to knowledge in the organizational sciences
TH
C4 Define inductive and deductive methods for generating knowledge What are the
advantages and disadvantages of each Under what conditions is each
appropriate
C5 Daft (1985) in Why I Recommended That Your Manuscript Be Rejected and
What You Can Do About It said that poor theoretical development is the
primary reason he recommended manuscripts be rejected when reviewing for
AMJ and ASQ
Why is theory considered so important
Give an example of a good theory and explain the elements that make it a strong
theory (Focus on theory development not on the content of the specific theory)
C6 You have undoubtedly heard the criticism of certain published articles in our
field being atheoretical Spoken as a criticism it suggests that research articles
should have theory Should every empirical article have theory Why is theory
important What are the hallmarks of good theory
2 RESEARCH DESIGN
A) Research Design Terms
5) Define internal and external validity Which is more important and why (It is not okay to
say they are equally important)
A1 Define (and discuss important features or issues concerning) the following
constructs of research design (Define any five terms)
1 Internal validity 6 Quasi-experimental
design
2 Stratified Sampling 7 Random Assignment
3 Solomon Four-group
design 8 Differential mortality
4 Factorial design 9 Demand
characteristic
5 External validity 10 Regression to the
mean
B) Level of Analysis
B1 IO psychologists have traditionally categorized themselves as being more micro or
macro in orientation usually falling toward the micro end Recent concern for what
has been termed the levels of analysis or cross-level approach has added a third
category - meso What is the meso level Is this just academic hairsplitting or re-
naming or is there a fundamental difference in this research strategy in contrast to
micro or macro Provide an example from some research domain of interest to you
that illustrates your conclusion of no real difference or important difference
C) Cross-Sectional vs Longitudinal Design
13) What are the benefits of a longitudinal design over a cross-sectional design in a non
experimental (correlational) study What are the disadvantages Why donrsquot we see
more longitudinal research
C1 The use of cross-sectional research designs continues despite many calls for
replacing them with longitudinal designs (a) What are the main strengths of
cross-sectional designs (b) What weaknesses do they have that longitudinal
designs supposedly counter (c) What are the implications of cross-sectional
designs for theory development (Consider internal and external validity)
C2 A good number of research efforts on the micro (OBHR) side rely on cross-
sectional designs in which surveys are used to collect both IVs and DVs from the
same respondent What are the various problems associated with such a design
What changes could be made to this design to alleviate andor eliminate these
problems What are the downsides of the new design (add in conveniencenon
probability samples)
C3 What are some of the major strengths of a longitudinal design Why dont we see
more of them
C4 Assume that you are analyzing a large sample of longitudinal survey data TH
Identify two characteristics of your data that would make ordinary least squares
regression (OLS) inappropriate for conducting analyses For each of these
characteristics describe an alternative analysis that is superior to OLS
D) Qualitative vs Quantitative Designs
D1 Compare and contrast the objectives strengths and weaknesses of
qualitativeobservational methods (eg ethnography) versus quantitative methods
(eg survey) in conducting empirical research on macro organizational issues Be
sure to consider issues of reliability generalizability validity ethics and
practicality in your answer Describe situations where one method or the other
may be most appropriate
IC
D2 In recent years a number of individuals have taken the position that qualitative
research is superior to quantitative research a Compared with quantitative
research what are the principal strengths of qualitative research b Compared
with quantitative research what are the principal weaknesses of qualitative
research
E) Observation vs Experiment
E1 Compare and contrast the objectives strengths and weaknesses of observational
methods (eg ethnographic methodology) and experimental methods Be sure to
consider issues of precision generalizability and realism in your answer Consider
also situations where one methodology or the other might be most appropriate
F) Laboratory vs Field Research
F1 Of the various research approaches available to organizational researchers
laboratory experiments are held up as an ideal because of their potential for high
internal validity On the other hand field research including participant observation
and field experiments have high potential for external validity Discuss specifically
the strengths and weaknesses of laboratory versus field experiments How would
positivist researchers think differently about these tradeoffs than would
phenomenologists
F2 In conducting an experiment in the laboratory or designing survey research there are
certain unique opportunities and limitations of each research strategy A) Describe a
hypothesized relationship between two constructs an independent and a dependent
variable in a substantive area of your choice (eg Strategy OB HRM
Organizational Theory) provide a verbal mathematical and graphical statement of
that hypothesis B) Briefly discuss how you would examine this hypothesized
relationship in a laboratory using experimental techniques versus a field survey using
correlation techniques C) Discuss what may be considered typical strengths and
weaknesses of each strategy regarding issues of precision and control in the
manipulation or measurement of the variables of interest realism of the context for
the participants and generalizability of the findings to other elements of a chosen
population D) Finally discuss advantages if any of using laboratory and field
survey methods in tandem
G) Experimental Design
2) A colleague suggests to you that only true experiments can provide useful results in
science Why might she say this What would you offer as a defense for the role of quasi-
experimental and non experimental designs in the context of the social science In
answering this question make sure you identify the defining characteristics of each design
type
9) Why and when should we be concerned about non response in research What are the
things we can do to try and decrease non response (or increase response rates)
11) Why might a researcher choose to utilize an experimental design that incorporates pretest
measure on the DV
G1 Experimental designs oftentimes come under attack due to perceived limitations in
external validity (a) Relative to other design types what strengths and weaknesses
do they offer (b) What experimental design structure is the strongest Why (c)
What is the relevance of research design for results and theory development
G2 Meta-analysts often investigate whether the quality of research design (eg
randomized experiments vs non-randomized designs) influences average effect
size In their meta-meta analysis of psychological educational and behavioral
treatments Lipsey and Wilson (1993) found that In a given treatment area poor
design or low methodological quality may result in a treatment estimate quite
discrepant from what a better quality design would yield but it is almost as likely
to be an underestimate as an overestimate (p1193) A few methodologists (eg
Shadish) have attempted to identify factors that may explain the relative magnitude
of effect sizes from randomized and nonrandomized experiments Please review
these findings and add your tentative model of the conditions under which random
experiments will produce larger smaller or equal effect sizes relative to
nonrandom designs Discuss possible implications for research design in the
context of real-world interventions
G3 Analysis of covariance and randomized blocks designs are sometimes referred to as
noise-blocking designs Explain what this means and give an example of (a) a
randomized blocks experiment and (b) an analysis of covariance experiment Keep
your examples simple Describe how such designs are noise-blocking when used
with randomized assignment of subjects to experimental condition and contrast
that with the role such designs serve in quasi-experimental designs
G4 Team performance in Bafko Industries varies considerably across teams and from
month to month The senior VP in charge of team development thought that a team
training program could improve the performance of these teams A consultant
convinced him that his firms training program which lasted only one week and
cost only $25000 per team) could raise the performance of Bafkos teams The VP
however wanted to experimentally test the efficacy of this training program before
he adopted it widely throughout the firm So the consultant suggested the following
experimental test
There were 48 teams in Bafko that showed significant variation from month to
month in their level of performance The consultant chose the 24 worst performing
teams based on last months data and assigned them to the training group After
all he argued these were the ones who most needed it The other teams were
assigned to the control group The training group received the training program
(lasting one week) at the beginning of the next month while the control group
teams did their normal routine Performance scores were gathered at the end of the
month The results showed that the training group teams had a significantly larger
rise (ie statistically significant) in their performance than did the control group
teams (who as a group did not improve at all) The consultant proudly displayed
these results and argued that they convincingly demonstrated the efficacy of his
program
How would you advise the VP Specifically what is the validity of the consultants
conclusions If you think he might be mistaken what specific threats to internal
validity are particularly plausible
G5 Consider the following design
N O Xa O
N O Xb O
N O Xc O
N O O where
Xa Xb and Xc represent different levels of a training program that varied in its
length across three different work groups In group a the training time was 40
hours in group b it was 30 hours and in state c it was 20 hours The training was
designed to instill customer service values in the team members O represents a
measure of customer service attitudes measured with a 20-item Likert scale This
measure was administered one week before the training program and 3 months
later The researcher hypothesized that the training program would improve
customer service attitudes and that longer training would have stronger effects
The design is a non-equivalent groups design because people were not randomly
assigned to groups even though groups were randomly assigned to treatment
condition Each group has a sample size of 36 members The reliability of the
customer service attitude scale was 78 at the pretest and 80 at the posttest The
pretest means were as follows
Group A 26
Group B 23
Group C 27
Control Group 25
a Construct a regression model that will test the researchers hypothesis Be
explicit here describing each variable in the model and what regression effect(s)
you would expect to find if the hypothesis were correct (Hint everything you need
to know is in Trochims chapter 11 and what we discussed in class) (10 points)
b Describe any serious threats to internal validity (10 points)
c Discuss how you might amend this design to improve its internal validity(10
points)
G6 Often in organizational research the researcher is faced with having only one group
on which to experiment and thus cannot use a control group when conducting
experiments This occurs for example in taxation experiments when you cannot
selectively apply new tax laws to different groups or when you wish to test the
efficacy of an incentive plan that must be applied to all members of a company In
such situations the researcher must be creative in assembling a quasi-experimental
design that has high validity (and usually the challenge concerns internal validity)
Consider the following scenario
A manager of a retail store wants to test the efficacy of an incentive program in
changing the selling behaviors of her retail sales clerks Specifically she wants to
test a behavioral reinforcement program in which sales peoples behavior is
recorded on in-store video cameras The tapes are analyzed each night and the
experimenter tabulates the frequency of various behaviors (eg offering assistance
to customers restocking items straightening up displays suggesting accessory
items to accompany the items that a customer is purchasing) The manager then
rewards the clerks with a monetary bonus based on the frequency of desired
behaviors She would like to conduct a valid experiment to see what effect such an
incentive program has on employee behavior but because of concerns about
employee morale she cannot assign clerks to treatment and control groups Instead
she has to apply the experimental treatment to everyone in the store She learned in
her research methods class (which the company requires all its managers to take)
that a single group experimental design typically has very low internal validity
Your job as a consultant is to help her design an experiment given her constraints
that would produce interpretable (ie internally valid) results Describe the details
of the design you would recommend using the notation in Trochim (2001) If the
design you come up with has a specific name use it As part of describing your
design discuss how the data would be analyzed and what particular effect you
would look for
G7 Why are experimental research designs held in such high regard
G8 Compare and contrast experimental quasi-experimental and correlational research
designs What characteristics separate these three designs What are their
advantages and disadvantages especially in comparison to one another
G9 What is the difference between a within-subjects experimental design and a
between-subjects experimental design When might a within-subjects design be
appropriate When might it be inappropriate
G10 Describe the difference between a basic within subjects and between subjects
experimental design What are the advantages and disadvantages of each
especially in comparison to one another Give an example from your area of
research in which each would be appropriate
G11 What are the major threats to the internal validity of a pretest - post test
nonequivalent control group design How can this design be improved with regard
to increasing a researchers ability to make causal inferences
G12 A production manager is interested in testing the hypotheses that participation in
quality circle programs will result in increased productivity and reduced
absenteeism A questionnaire is administered to a group of 92 employees
concerning their attitudes toward such programs and 46 with the most favorable
attitudes who are willing to participate are selected for the treatment group The
remaining 46 are the control group Measures of performance (unitsmonth for the
group) and absenteeism (lost daysmonth for the group) are kept over a three month
period during which the treatment group has weekly quality circle meetings The
results are as follows
Month 1 Month 2 Month 3 Month 1 Month 2 Month 3
Performance Absenteeism
Treatment 100 115 121 6 9 4
Control 110 108 113 6 8 5
The manager calculates t tests between month 1 and 3 The only significant
difference is performance for the treatment group so the manager concludes that
quality circles raise productivity but do not have an effect on absenteeism What
are the primary threats to internal and external validity in this study What are
possible alternative explanations for the differences (or lack of differences)
between the two groups What additional information might help explain these
results
G13 One stream of current strategy research contains event studies In these studies
investigators basically correlate the reaction of a financial market to the presence
andor absence of the occurrence of some event at a firm (eg the resignation of a
CEO) In a different approach to such a study suppose that one investigator (Jean)
conducts a natural field experiment on the effects of competitor mergers on a
firms environmental scanning activity Through previous arrangement Jean has
been working with 5 medium-sized computer hardware and 5 medium- sized
software firms on the west coast Shes been collecting a paper trail of internal
memos reports and phone calls that might measure environmental scanning
activity Shes been finding that the firms in both industries do about the same
amount of scanning (no significant differences) However in the midst of her data
collection Norton announces a merger with Symantec (software) A year later
Jean compares the amount of post-merger environmental scanning in the software
industry with that in hardware industry Just as Jean had hypothesized a t-test
shows a greater amount of post-merger scanning among the software firms She
concludes that her hypothesis was supported mergers of competitors cause an
increase in scanning
Critique the study described above in terms of its design flaws Identify the design
Jean used Briefly allude to problems the study has with external validity but
concentrate on the Cook and Campbell threats to internal validity Provide a
rationale for why each threat is or isnt operating in the study Link each of the
relevant threats to the specific constructs being studied (mergers and environmental
scanning) Finally do a summary evaluation -- what can be learned from this
study
H) Quasi-Experimental Design
H1 The University of Mississippi observed that the graduation rate of students with poor
grades during their freshman year was much lower than those with better grades
Wanting to improve the chances of these low performing students they tested the
effects of a new rule for freshmen The rule stated the following At the end of their
first semester all students with a GPA between 200 and 225 must register for
EDUC 1003 during their second semester Students with a GPA lower than 200
were put on academic probation EDUC 1003 consisted of a course whose objective
was to help students develop good study skills The theory was that poor study skills
were a significant cause of poor academic performance and that study skills could
be learned
They wanted to evaluate the effectiveness of this intervention so they collected data
on the GPAs of students beginning with their first semester and continuing through
to their third semester At that point they wanted to analyze the data to determine
whether the new rule was making a significant difference in the students academic
performance
What is the best way to analyze these data to reach an interpretable conclusion
Describe your approach and then discuss the major threats to validity that it has
Their sample size of students was as follows
Total N= 3454 (these are students who completed all 3 semesters)
Number of students with first semester grades between 200 and 225 (and thus took
EDUC 1003) was 956
H2 A nationwide furniture company wants to determine if a diversity training
program will improve individual sales performance on the floors of its urban retail
outlets A group of 45 salespeople in one city were given two weeks of training
Measures of individual sales performance were taken once two months prior to the
program and once two months after Forty-five salespeople (who did not receive the
training) in a similar city had the same measures taken at approximately the same
points in time The training group increased their average weekly sales from $14000
to $16500 while the non-training group improved theirs from $13000 to $14500
The change for the training group is statistically significant the change for the non-
training group is not
How would the interpretation of these results in this quasi-experimental design
differ from a true experimental design What are the threats to internal validity in
the above study and how might they be operating (be specific) What additional
information and analyses would be useful in controlling for these threats
H3 An accounting firm is interested in determining if a re-training program will reduce
errors made by its audit teams A group of 45 auditors in the home office location
are given two weeks of re-training Measures of the frequency of detectable errors
are taken once two months prior to the program and once two months after Forty-
five auditors in similar office at a branch location have similar measures taken at
approximately the same points in time The training group reduced their average
number of errors per audit from 8 to 3 while the non-training group reduced theirs
from 11 to 9 The change for the training group is statistically significant the change
for the non-training group is not
How would the interpretation of these results in this quasi-experimental design
differ from a true experimental design What are the threats to internal validity in
the above study and how might they be operating (be specific) What additional
information and analyses would be useful in controlling for these threats
H4 Describe the main classes of threats to validity that are found in quasi-experimental
research designs
H5 Dr Delta an organizational development consultant was hired by a firm that has
600 pizza parlors nationwide to assist in implementing organizational changes that
he hopes will result in higher levels of job involvement At the outset of the study
subjects had jobs with very low levels of enrichment and were paid on an hourly
basis He designed an experiment in which stores were randomly assigned to one of
three treatment conditions Condition 1 subjects experienced job enrichment (JE)
and a change to performance-based pay (PBP) Condition 2 subjects experienced
only JE and Condition 3 subjects experienced only PBP The parlors were
sufficiently far apart from one another and communication among the parlors so
poor that subjects in any parlor were totally unaware of changes made in other
parlors At the end of 18 months he measured the job involvement levels of workers
and then tested for differences between the three conditions using a standard one-
way analysis of variance In view of Dr Deltas design answer the following
questions
How sound is Dr Deltas design Comment on the weaknesses of the design
I) Interrupted Time Series Design
I1 What threats to internal validity are and are not ruled out by an interrupted time series
design that includes the introduction of a treatment and its removal at a subsequent
time period List and explain In the process be certain that you provide a diagram
that illustrates such a design
J) Validity Some Questions are about the validity of a measure others about experimental validity)
10) Identify four threats to internal validity and briefly describe what they mean
J1 It was some time ago that the tripartite view of validity was abandoned in favor of a
unitarian view in which different evidentiary bases for validity might be put forward
Binning amp Barrett (1989) represent an attempt to place multiple evidentiary bases into a
single framework Cook amp Campbell (1979) describe four aspects of validity but they
arent really meant to represent evidentiary bases Adding to the confusion is the fact
that while Binning amp Barrett and Cook amp Campbell use some of the same terms these
two pairs of authors clearly mean different things by these terms and intend for them to
be used in different ways Your task is to 1) Describe the evidentiary bases discussed
by Binning amp Barrett 2) Describe the aspects of validity described by Cook amp
Campbell 3) Describe the similarities and differences between the two lists including
the different purposes served by the two lists and 4) Present a single framework that
incorporates both This last task is the most important of the four
J2 What are the types of validity How would each affect an empirical study IC
J3 Define both internal and external validity Which is more important (it is not okay to
say that they are equally important) Defend your reasoning
J4 Why might someone argue that the construct validity of a measure can never really be
established
J5 Describe each of the following forms of validity content convergent discriminant
criterion-related and construct How is each assessed How do they related to each
other Which is most important (Make sure you defend your answer)
J6 Define and explain 6 of the 8 types of validity listed below and describe the type(s) of
information each provides Choose one specific type of study as an example (eg
cross-sectional study experiment quasi-experiment simulation ethnography etc) and
compare and contrast the usefulness and importance of each type of validity for that
type of study
-- Concurrent validity
-- Construct validity
-- Content validity
-- Convergent validity
-- Discriminant validity
-- Statistical conclusion validity
-- Internal validity
-- External validity
J7 Designing empirical research has been called making a series of trade-offs
Unfortunately decisions that are made to increase one desired quality (like internal
validity) can also decrease another desired quality (like external validity) For each of
the issues below discuss the concerns involved (ie the trade-off) and identify the
qualities that are being increased or decreased
a laboratory vs field study
b using a 5-item measure vs a 1-item measure
c using a student sample vs a sample of full-time employees
d using a sample of employees from one company of 5000 vs 500 employees from
each of 10 companies
e collecting your data using one method vs collecting your data using multiple
methods
J8 There are four major types of validity in social science internal validity external
validity construct validity and statistical conclusion validity Please address the
following three issues concerning validity
a What is the meaning of the four major forms of validity (ie internal and external
validity construct validity statistical conclusion validity)
b Are there trade-offs that can or must be made among the four types of validity
d Describe how the concept of validity varies across the research traditions of
experimental vs observational research
IC
J9 The quality of research is often assessed by examining validity issues As you are
aware there are numerous typesforms of validity (eg internal and external validity
construct validity statistical conclusion validity) These types of validity address
different aspects of the research process For this question please address the following
issues
a What is the meaning of the four major forms of validity (ie internal and external
validity construct validity statistical conclusion validity)
b Should there be a priority among these forms of validity If yes why If no why not
c Does the concept of validity vary across research traditions (ie experimental vs
observational research) If yes why If no why not
J10 External validity has received considerable attention in the social and behavioral
sciences Some researchers argue we are too concerned with the external validity of our
findings while other researchers argue that we are too unconcerned with external
validity Several points of view have been developed to explain what is external
validity When answering this question please be sure to address at least the following
issues
a Compare and contrast alternative conceptualizations of external validity
b Some researchers have argued that the role of external validity is invariant across
research traditions (ie experimental vs observational research) Defend the
perspective that the role external validity is invariant across these two research
traditions In addition present the weaknesses of this perspective
J11 In designing a research study researchers must consider trade-offs between internal and
external validity Explain what is meant by internal validity and external validity What
is the nature of these trade-offs How would you evaluatedetermine which is more
important internal or external validity for a particular study Why is this such an
important issue in organizational studies
J12 A researcher conducted a quasi-experiment to test the effects of participative decision
making (PDM) on job attitudes of employees Employees from different departments in
a large organization were assigned to either a treatment group (PDM implemented) or a
control group (no PDM) Random assignment was not possible because of work
schedules coordination of tasks etc Thus the design can be considered an untreated
control group design with pretest and posttest and is represented as follows (where
O=observation X = treatment)

100 being extremely satisfied) How amenable are these results to causal interpretation
What is (are) the major threat(s) to internal validity B if any B for this type of design
given these results What steps can be taken to assess the extent of this (these)
threat(s)
K) Data Collection Methods
14) Describe the various methods of data collection (eg survey interview observation etc)
available to a social scientist What are the advantages and disadvantages of each relative to
each other
K1 Within micro organizational research much criticism has been raised concerning
the reliance on self-report survey data What potential problems does self-report
survey research raise How big of a problem do you think this is
K2 There are a number of methods for collecting data (eg survey interview archival
etc) that are available to a social scientistorganizational researcher Discuss each in
terms of their strengths and weaknesses both on their own and in comparison to one
another
K3 Pick an important construct in your favorite area of management research for which
there is some controversy about how it should be measured or operationalized (eg
environmental munificence or growth need strength) Give the prevailing verbal
definition of the construct and analyze the measurement controversy from two
broad angles First discuss how the controversy may or may not stem from claims
about how one measure is better or worse than another because it (or the other) is an
(a) archival record (b) direct observation (c) social report or (d) self-report That is
what are the relative strengths and weaknesses of each of these types of
measurement for the construct youre discussing Second discuss the construct
validity of the most commonly used measure(s) of this construct To answer this
second part you need to discuss just what construct validity is and how it can or
cannot be demonstrated In the situation you describe what could be done to
demonstrate or improve the construct validity of existing measures
K4 Interviewing in some form has been the workhorse for data collection in a variety
of research traditions positivistquantitative ethnographic feministpost-modernist
and increasingly historical research While each tradition elicits information from
respondents the goals and processes involved in interviewing vary considerably
across research traditions Discuss the purposes of the interview the relationship
between data and theory the roles assumed by the interviewer and the respondent
and the relevant criteria for assessing the validity and reliability of the information
obtained In addition compare and contrast the use of the interview as a data
collection method in the positivistquantitative tradition with its use in one of the
alternative traditions
L) Common Method Variance
L1 Many of us have had concerns about the reviews of our survey research which
suggest that data analyses of surveys are biased because of common method
variance effects of individual differences such as negative mood negative
affectivity and social desirability and the reliability and validity of the constructs
we are attempting to measure Define how these problems affect a research issue in
organizational behavior and the steps that might be taken to minimize such potential
criticisms of papers based on analyses of self-reported data through survey
instruments
L2 In a series of papers by Spector (1994) Schmitt (1994) and Howard (1994)
published in the Journal of Organizational Behavior arguments were provided for
and against the use of self-report questionnaire measures One of the issues
discussed that could limit conclusions drawn from relationships observed using self-
report measures was method variance What is meant by method variance what are
its sources and what impact is it expected to have on research findings
M) Sampling
M1 The manufacturing census samples all plants of 250 employees or more For
plants of 5-249 employees it takes a size proportional sample Plants of 1-4
employees are not sampled What challenges does this sampling method provide
to researchers What could you do to account for these problems if you were
TH
studying organizational (not plant) growth
M2 New York State has approximately 250000 employees in over 70 state agencies
commissions and boards ranging in size from approximately 50 to over 5000
employees Assume that you wanted to draw a representative sample of 1000
employees Describe two ways that you could draw such a sample and briefly
describe the advantages and disadvantages of each of these sampling approaches
IC
M3 The director of a national non-profit agency with approximately 10000
employees located primarily in regional offices in each of the 50 states the
United States has approached you and asked you to develop a study
(organizational survey) of organizational culture within the agency The agency
is about to embark on a variety of change initiatives including developing team
structures and the study is meant to examine various elements of organizational
culture that are potential barriers to change The director has indicated that he
would like to have the data analyzed at both the individual and office level of
analysis Because of funding limitations the agency will only be able to send the
survey to 1000 employees The director has indicated that there are three ways
of sorting employees all employees listed alphabetically all employees listed
alphabetically by state and all employees listed alphabetically by region (there
are between five and ten regions per state) Given these three ways of sorting
employees describe at least three different sampling approaches and the
advantages and disadvantages of each
M4 In your role as Teacher of Organizational Studies you are asked to prepare a
tutorial for beginning doctoral students on sampling design Assume that this
tutorial is part of a basic class in research design and that students in this class
have had a basic statistics course up to and including multiple regression Your
tutorial should focus on briefly defining and explaining the differences between
probability and non-probability samples You should make sure to present and
describe several types of probability samples (eg random systematic
stratified etc) and non-probability samples (eg convenience snow-ball quota
etc) and discuss general principles for when to use a probability vs a non-
probability sampling design For each sampling design you should also provide
at least one clear example of a situation where this type of sampling design is
appropriate
N) Cross-Cultural Research
N1 Discuss the problems in conducting cross-culturalnational comparison in terms
of (1) conceptualization and (2) research design and data collection
Define the three levels of measurement invariance How would the problems that
you have identified in part (a) affect measurement invariance How would you
examine measurement invariance by confirmatory factor analysis
TH
N2 Explain why using national boundaries as independent variable in cross-cultural
studies may not be appropriate in terms of theory and research methods What
alternative ways would you recommend
IC
O) General
O1 In your readings research has been described as choices among conflicting goals
(desiderata) For instance when choosing among research strategies a researcher
must choose among the desiderata of precision realism and generalizability The
trade-offs among desiderata occur for all aspects of research that is for the selection
of theories the treatment of independent variables research strategies the selection
of the problem to study rules of evidence for determining the meaningfulness of a
research finding and even the frameworks that describe the research process
Discuss what you see as the major trade-offs for each of the following aspects of
research That is discuss what you see as the major strengths and weaknesses
(advantages and disadvantages) of each aspect
a The trade-offs between internal and external validity
b The manipulation of the independent variable vs the observation of the
independent variable
c Basic vs applied research
3 DESIGNING A RESEARCH STUDY
A) General (Research Design)
3) Why is control so important in research design What are the different ways it can be
achieved (give a brief description of each control method) What are advantages and
disadvantages of each
A1 It has become almost a truism to note that the choice of methods influences theory
and questions data and conclusions (the causal direction might also be reversed)
Briefly discuss how the methods used have influenced research in any two of the
following areas leadership power and politics organization culture organization
justice Compare and contrast as possible Suggest some potentially fruitful
methodological directions for future work in these same topical areas and dont be
shy about reflecting on broader issues of how the field of organizational behavior
constructs its realities Lastly tie your discussion and reflections back to your own
future as a researcher what lessons or guidance do you derive from your
understanding of these issues
A2 Characterize as fully as possible what you see to be the methodological approach or
approaches in strategic management research Is there a dominant method or a wide
variety Discuss the reasons for the situation What are the advantages benefits etc
of the approach(es) in use What assumptions (ontological epistemological
ideological) do they embody Are current efforts ideal or at least adequate Are
there other approaches that could be useful If so how might researchers be
encouraged to use these as well If you see no advantage to more variety in
methodological approach support that point of view
A3 Describe a research question or area of interest to you and why you think it is not
only of interest but significance Using your understanding of research methodology
describe two ways of pursing the question that are as divergent on as many
dimensions as you can imagine Describe the advantages and disadvantages of each
approach How strong a link or fit is there between a research question and a
method
A4 In his 1957 article entitled The two disciplines of scientific psychology Cronbach
discussed the assumptions goals and methods used in experimental methods and
correlational methods in psychology
a According to Cronbach what is the main difference between the two disciplines
b Discuss the strength and weaknesses of each discipline
c What if anything could be done to improve the situation
B) Designing a Research Study
B1 Cook and Campbell describe the experiment as the research design with the
greatest methodological rigor However given the constraints present in most
organizations I-O Psychologists cannot often conduct experiments in applied
settings and must settle for techniques with less control than experiments
Describe a study to investigate the relationship between participation in a
supervisor training program and work performance which could realistically be
conducted in an organization If an experiment is not possible describe how you
would go about maximizing your ability to draw valid conclusions from your
design
B2 The XYZ Co has recently developed a sexual harassment web-based training
program The developers claim the program will cut training time and costs and
will be as effective or more effective than classroom-based sessions They
believe that this will be due to the increased availability of the program and the
ability for participants to review program material on demand Before the XYZ
Co developers launch this product they want you to determine if their claims
have merit Explain how you would design a study for this purpose
B3 Research suggests that demographic diversity improves group creativity but
reduces group efficiency Some argue that demographic diversity is just a proxy
for value and experience diversity and that demographic diversity on its own is
meaningless Design a test to settle this argument
TH
B4 E-mail has become a common form of communication in organizations and is
used for both formal and informal communication Because it has become so
IC
popular some people complain that the frequent use of e-mail leads to
miscommunication because they receive communications in e-mail that should
be accomplished through face-to-face or telephone conversations where there is
an opportunity for interaction You are interested in looking at this
phenomenon You are most interested in describing how e-mail is used for both
formal and informal communication and in examining the effect of the e-mail
use on organizational communication effectiveness Design empirical research
to address those issues
Describe your study in detail thoroughly explaining the research design
sampling plan data collection procedures ethical issues and proposed data
analysis for your research design Be sure to discuss the internal and external
validity of your research Which validity threats are ruled out and which
remain
REMEMBER Be thorough Your research design should demonstrate that you
are a competent researcher who is knowledgeable about the proposed research
methodology or methodologies Therefore be sure that you carefully describe
and give technical explanations for each component of your research
B5 Choose a specific situation involving employee selection eg artists for an
advertising agency (a) What strategy would you use in selecting the selection
measures (b) How would you combine the measures eg which measures
would you combine in a compensatory manner and which is a noncompensatory
manner (c) How would you assume test fairness defining various measures of
the term (d) How would you make final selections (e) How would you
validate your procedure (f) What considerations would enter in if your
company were too small to provide validation data (g) What difference would
it make if you were developing a procedure for deciding whether trainees
should be promoted as opposed to making new hires Please note--emphasize
but do not limit yourself to statistical issues
B6 There is evidence in the marketing literature of a non-monotonic relationship
between the expectations that customers have for retail service and their
eventual level of satisfaction with that service That is as a customers
expectations for service increase so does their eventual service satisfaction --
up to a point After that point the greater the expectations the lower the
eventual satisfaction Develop a hypothesis that includes a moderator variable
that might account for this evidence Give some reasonable rationale for it State
your hypothesis verbally as an equation as a directed graph (circle amp arrow
diagram) and as an X-Y function chart Discuss how it would or would not be
possible or useful to test your hypothesis via a laboratory experiment In your
discussion cover how and why a researcher could (not) manipulate the
independent constructs involved (mode X) whether or not random assignment
to conditions (mode R) is possible (including how may conditions would be
necessary) which alternative constructs could or could not be controlled (mode
K) and which constructs should be measured (mode Y)
B7 Assume you are the chairperson of a committee that must evaluate
undergraduate programs at your university Your task as chairperson is to
devise an approach (a design a research strategy a set of measures) that will
allow you to evaluate undergraduate programs Make sure that your approach
can be used in the future and at other comparable universities When developing
your plan be sure to address at least the following issues
a the type of design you would select Compare and contrast the selected design
with another possible design
b the type of research strategy you would select Compare and contrast with
another possible strategies
c discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
B8 Assume you are an organizational research design expert assigned to the
Strategic Planning Department of a large multi-national manufacturing firm
The Department has developed a new PC-based software package called
STRATPACK The software (and a one-week training course to learn how to
use it) is intended to improve the long-range planning ability of middle and
upper-level managers
Your job as research design expert is to devise research (a design a research
strategy a set of measures) that will allow you to evaluate the effectiveness of
the STRATPACK program Describe a research design for evaluating the
program Make sure that your research approach can be used in the future and at
all sites in the company When developing your plan be sure to address at least
the following issues
a discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
b the type of design you would select (eg a design where you manipulate the
independent variable versus observe the independent variable) Compare and
contrast the selected design with another possible design
c how your design deals with the major forms of validity Be sure to examine at
least internal external and construct validity
B9 Assume you are a consultant hired to evaluate the effectiveness of an industrial
safety program undertaken by a large manufacturing organization The safety
program is a behavioral one that provides rewards such as monetary bonuses or
extra paid vacation days for safety behaviors in terms of accident-free days
weeks etc Your task is to devise an approach (a research strategy a design a
set of measures and a general analysis strategy) that will allow you to evaluate
the safety program Because of the potential for the influence of many
extraneous variables on any safety program it is difficult to design research a
single cross-sectional study than can evaluate the impact of a single safety
program How would you design a study to evaluate the impact of the safety
program When developing your plan be sure to address at least the following
issues
a the type of research strategy you would select Compare and contrast with
another possible strategies
b the type of design you would select Compare and contrast the selected design
with another possible design
c discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
B10 One of the most important areas of research is forecasting of human resources
needs based on strategic positions of organizations For example NY State must
carefully forecast its human resources needs as it proceeds with significant lay-
offs of state employees Future human resources needs are generally evaluated
by either statistical ie regression or simulation or clinical judgment i e
supervisors judgments methods
a Design a single study that addresses the empirical question of whether
statistical or judgmental methods are better for forecasting human resources
needs You may discuss a program of research but please be quite specific in
your description of the first study
b What are the critical methodological issues in doing this kind of research
c What are the critical applied (or practical) issues in doing this research
d Are the issues in b and c related
B11 In the past decade computinginformation technology has changed many
aspects of organizational life For example the technology can make increased
decentralization possible by improving communication between central offices
and field offices Computer networks and word processors can enhance group
empowerment by making it possible for team members to create and edit
written group products quickly even if the individuals are at different locations
Some have argued that computinginformation technology will foster the
paperless productive office nevertheless others argue that the technology only
increases paper and reduces office productivity You are applying to the
National Science Foundation for a grant to conduct research that examines the
impact of computing information technology on organizational decision
processes The NSF application procedure imposes five basic requirements that
your research design must fulfill in order to receive funding Note A very
significant factor affecting NSF grant decisions is a clear demonstration that the
researcher is knowledgeable about the research methodology used Write your
response to each of the following five grant requirements Be sure not only to
respond to the requirement but also to demonstrate your research
competence
1You must design a study that uses two different methods
(interviewobservation survey experiment or quasi-experiment) Describe your
two methods in detail and provide a rationale for the key elements (eg
sampling data collection proposed analysis) of your methods Be sure to
discuss and evaluate the internal and external validity of both methods
2 As part of your research design you must select a conceptual (latent) variable
central to your proposal (use centralization of decision making as your
variable) and describe how you will develop your own measure (You may not
simply use off the shelf instruments)
3 You must describe how you will test for the reliability of the measure
(centralization of decision making) you developed in step 2 The NSF insists
that you describe how you will evaluate both the temporal stability and the
internal consistency of your measure Be sure to discuss what temporal stability
and internal reliability mean and how they are related
4You must describe how you will assess the validity of the measure
(centralization of decision making) you developed in step 2
5 NSF requires a brief statement and defense of the philosophy of science
underlying your research Discuss your position and show how your research
design is consistent with your philosophy
B12 Many organizations in the United States economy have installed some form of
Empowered Teams as an alternative or supplement to traditional bureaucratic
structure Preliminary evidence of the effectiveness of empowered teams
however is mixed--some organizations have claimed success and others have
reported failures The evidence however is predominantly anecdotal--written
for trade magazines by the organizations themselves There are few rigorous
empirical studies assessing the effectiveness of empowered or self-managed
teams You are applying to the United States Department of Labor (USDOL) for
a grant to conduct research that examines the effectiveness of empowered
teams The application procedure of the USDOL imposes three requirements
that your research design must fulfill in order to receive funding Write your
response to each of the three grant requirements The importance of each section
is implied by the evaluation points allocated by the USDOL to each of the three
requirements given in parentheses
1 (50 points) Your study design for assessing Empowered Team effectiveness
must use two different methods (interview observation archival analysis
survey simulation experiment or quasi-experiment) Describe in detail and
thoroughly explain the sampling plan instrumentation data collection
procedures and proposed data analyses for both methods Be sure to discuss the
internal and external validity of both methods and how the two methods
complement one another
2 (30 points) As part of your research design you must select one conceptual
(latent) variable central to your proposal and describe how you will develop
your own operationalization of the measure (You may not simply use off the
shelf instruments) Use the concept of group morale to demonstrate your
operationalization methodology Be sure to explain very explicitly to the
USDOL how you will assess the validity and reliability of the group morale
measure you are developing
3 (20 points) The USDOL traditionally has funded research conducted only
within the general paradigm of logical positivism but now is more open to other
research paradigms as well Your grant proposal must provide a statement and
defense of the explicit philosophy of science underlying your research Describe
your philosophy of science and show how your research design is consistent
with your philosophy
REMEMBER Be thorough You not only must design effective research but
you also must demonstrate to the USDOL that you are a competent researcher
It is absolutely vital to the USDOL that the principal researcher is
knowledgeable about the proposed research methodologies Therefore be sure
that you always carefully describe and give technical explanations for each
component of your research design and explain all technical terms (eg
Cronbach alpha KR-20 Likert scale)
B13 Assume that you are working as part of a research team that is responding to a
RFP (Request for Proposals) from a funding agency for research on work
socialization and newcomer adjustment The RFP calls for rigorous field
research that tests the effectiveness of theory-based interventions aimed at
facilitating the adjustment of new organizational members to complex andor
stressful work conditions The major goal of your teams research is to test the
effectiveness of a self-regulation intervention which trains newcomers to
identify and use relevant social information and cues to regulate work behavior
Your group hypothesizes that self-regulation training will be more effective
than other common treatments or interventions (eg realistic job previews
institutionalized socialization tactics)
You have been included in the team because of your methodological expertise
Your role is to design a rigorous field experiment or quasi-experiment to test he
effectiveness of the self-regulation training program REMEMBER THE
MAJOR CRITERION FOR FUNDING IS THE RIGOR OF THE RESEARCH
DESIGN Design a field study to include in the grant proposal Your proposal
should contain the following two sections
1 Study Design Construct and describe in detail an experimental or quasi-
experimental design to test the effectiveness of your intervention Describe in
detail the experimental groups (including how they will be constructed) the
research setting the sampling plan for study participants the treatment
manipulation and the data collection procedures Also indicate any control or
nuisance variables that may be measured
After describing the procedures write a justification of the design What threats
to validity does it rule out or limit and what threats to validity remain
II Measurement Describe the steps you would take to achieve valid and
reliable measure of the latent (conceptual) variable worker adjustment Your
team feels that as part of the proposal you must develop an original
operationalization of adjustment (thus you cannot simply use existing off the
shelf measures) Indicate in adequate detail how you would operationalize the
measure and indicate how you would demonstrate reliability and validity
B14 In describing their notion of the collective mind Karl E Weick and Karlene H
Roberts note Our focus is at once on individuals and the collective since only
individuals can contribute to a collective mind but a collective mind is distinct
from an individual because it inheres in the pattern of interrelated activities
among many people (p 360) Collective mind is not indexed by within-group
similarity of attitudes ideas or activities A collective mind is one in which
many people or many groups integrate their different attitudes ideas and
activities heedfully As Weick and Roberts note People act heedfully when
they act more or less carefully critically consistently purposefully attentively
studiously vigilantly conscientiously pertinaciously (p 361)
The idea of the collective mind as heedful interrelating is developed in the
following excerpt When people make efforts to interrelate these efforts can
range from heedful to heedless The more heed reflected in a pattern of
interrelations the more developed the collective mind and the greater the
capability to comprehend unexpected events that evolve rapidly in unexpected
ways When we say that a collective mind comprehends unexpected events we
mean that heedful interrelating connects sufficient know-how to meet situational
demands For organizations concerned with reliability those developments
often consist of unexpected non-sequential interaction (p366)
An example of heedful interrelating occurs as a pilot lands herhis aircraft on the
deck of an aircraft carrier The pilot does not actually land She is recovered
A recovery is an interrelated set of activities among air traffic controllers
landing signal officers the control tower navigators deck hands the helmsman
driving the ship etc These activities can be interrelated more or less heedfully
depending on the care with which the different units contribute represent the
situation and subordinate their activities to the single purpose of successful
recovery (p 363)
You are to design a two-part study
Part I You are to design a measurement study which assesses heedful
interrelating (ie collective mind) with a quantitative measure in a replication
of an aircraft carrier flight deck or other situation of your choosing Describe
your research strategies including operationalization of the variable selection of
the sample subjects data collection data analysis and so on for the purpose of
developing a measure of heedful interrelating
Part II Using the measurement tool developed in Part I and any other tools as
needed describe how you would design a study which would compare heedful
interrelating across organizations Choose at least one macro-organizational
variable (eg technology environment) as your basis of comparison Here you
must describe how you would make your selection of organizations to be
compared your data collection procedure data analysis and so on
B15 Many organizations in the United States have installed cross-functional teams to
counteract the silo mentality of traditional bureaucratic structure Preliminary
evidence of the effectiveness of cross-functional teams however is mixed --
some organizations have claimed success and others have reported failures The
evidence moreover is predominantly anecdotal--written for trade magazines by
the organizations themselves Since there have been few rigorous empirical
field studies assessing the effectiveness of cross functional teams the National
Science Foundation has decided to fund research on the topic
Assume that you are submitting a research proposal to NSF for a grant to
research the effectiveness of cross-functional teams Describe in detail and
thoroughly explain the research design sampling plan data collection
procedures ethical issues and proposed data analysis for your research design
Be sure to discuss the internal and external validity of your research Which
validity threats are ruled out and which remain NSF also requires that you
provide a statement and defense of the explicit philosophy of science underlying
your research Describe your philosophy of science and discuss how your
research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but
you must also demonstrate to NSF that you are a competent researcher It is
absolutely vital to NSF that the principal researcher (you) is knowledgeable
about the proposed research methodologies Therefore be sure that you always
carefully describe and give technical explanations for each component of your
research design and explain all technical terms (eg Cronbach alpha KR-20
Likert scale)
B16 Assume that you are submitting a research proposal to the Department of
Commerce (DoC) for a grant to research the effectiveness of virtual work teams
A virtual work team is a leaderless collection of individuals who are
geographically separate from one another and share their expertise using
internet media such as a listserver or Lotus notes The DoC requires that the
researcher use both qualitative and quantitative methods to gather data Describe
in detail and thoroughly explain the research design sampling plan data
collection procedures ethical issues and proposed data analysis for your
research design Be sure to discuss the internal and external validity of your
research Which validity threats are ruled out and which remain The DoC also
requires that you provide a statement and defense of the explicit philosophy of
science underlying your research Describe your philosophy of science and
discuss how your research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but
you must also demonstrate to DoC that you are a competent researcher It is
absolutely vital to DoC that the principal investigator (you) is knowledgeable
about the proposed research methodologies Therefore be sure that you always
carefully describe and give technical explanations for each component of your
research

[some recent article] Provide an argument given the current state of the literature
on this topic for which validity (or set of validities) is most critical at this juncture
in the field Finally given your critique and assessment design a follow-up study
that improves upon the key validity (or validities)
5 MEASUREMENT
A) Measurement Terms
A1 There are four levels of measurement rigor in management research Discuss each
one What properties do measurements at each level have (ie how much
information do the numbers from each level of measurement convey) How can the
numbers be changed (transformed) and still retain the properties of their
measurement level Pick one construct from a favorite research domain and give an
example of an operationalization of that construct at each of the four levels of
measurement rigor (provide arguments about why you think those examples reflect
each level) Lastly treat each examplelevel as a dependent variable in some
statistical analysis Given an example of a statistical technique appropriate for
analyzing data at that level of measurement rigor
A2 Define (and discuss important features or issues concerning) the following
constructs measurement (Define any six terms)
1 Construct validity 6 Item analysis
2 Likert scaling 7 Semantic differential
3 Cronbachs alpha 8 True score
4 Unobtrusive (trace) measurement 9 Generalizability theory
5 Interval scale 10 Criterion-related validity
11 Sociometric choice measures
B) Operationalization
B1 a) You are conducting a study which requires you to measure Hong Kong real
estate agents self-assessment of performance Since there is no existing
measurement available you have to develop the instrument by yourself
Describe how you would develop the measurement assuming that you have no
idea of how many dimension the construct has
b) Suppose you have developed an instrument consists of 20 questions
measuring 4 dimensions (5 items per dimension) from (a) You collected data
from another 300 real estate agents to validate your instrument Explain how
TH
you would use structural equations model (SEM) to examine the reliability and
validity of the instrument What are other concerns about reliability and validity
that are not addressed by this approach
B2 The research and business world have been fascinated with the concept of
organizational culture However operationalizing this construct has been a
difficult task Discuss the ways in which the construct has been operationalized
(eg technique static v dynamic sample selection generalizability) Critically
analyze each of these methodologies Then choose a methodology you would
use to examine organizational culture and defend your choice Describe how
you would study culture and what more would be known about culture as a
result of your study
B3 Suppose you are setting out to develop a new measure of a construct You want
this measure to be used in survey research and you want to establish its validity
and reliability Your goal is to have at the end of the process a measure that is
defensible and likely to be widely accepted by other researchers studying that
construct What steps would you take to conduct such a program of research
For each step explain the purpose of that step explain why that step is
important explain what methods and statistical procedures you would employ at
each step and explain what evidence you would hope to gather at each step
B4 Assume you are interested in constructing a new measure of (fill in with a
relevant variable from your field) Detail the major concerns that need to be
addressed and the steps that need to be taken in working toward validating this
new measure
B5 Assume that you recently read an article on workplace violence which you
found very interesting The authors argued that one of the predictors of
workplace violence was a construct called propensity to be violent and used a
one-item measure as follows How likely are you to become violent when
provoked You had serious doubts about the authors measure and decided to
develop your own
(a) How would you go about developing items to measure propensity to be
violent
(b) How would you determine whether the instrument was reliable
How would you determine whether the instrument was valid
B6 A concern in organizations is retirement of baby boomers within the next 5 -
10 years This concern is focused on the loss of older employees with skills
critical to the core business functions of organizations In order to continue to
have employees with those critical skills it seems necessary to retrain some
older workers However past practice in most organizations has been not to
retrain older workers for a variety of reasons mostly financial A researcher
working for the Human Resources Department of a large corporation - 13500
employees in 12 different plant locations - hypothesizes that the major reason
for not retraining older workers is ingrained in the culture of the corporation
IC
The researcher feels that older workers are not as highly valued as younger
workers in terms of their potential usefulness after retraining The researcher
searched the literature but found nothing in the existing literature to measure
the cultural value construct What should the researcher do to establish a reliable
and valid self-administered paper and pencil measure of this construct namely
the value of retraining older workers
a Please describe and explain the steps in temporal order that the researcher
must follow to develop a measure
b How would you evaluate the measure based on the technical requirements of
reliable and valid measurement as well as any practical issues in using the
measure considering the size of the employee population

take to develop an operationalization of the concept of organizational
effectiveness What standards and procedures would you use to determine if
your operationalization is valid
B9 One of the most important topics of recent research has been stress in the work

C10 Schmidt and Hunter (1996) described several types of measures typically used in
organizational research and identified the type(s) of measurement error affecting
each of them in various situations For each measure below indicate the types of
error and sources of error that are most likely to affect it Then indicate what
could be done to reduce errors of measurement andor what can be done to
control for errors statistically

C11 Suppose you had conducted research on the relationship between organizational
commitment and rigidity of organizational structure in 200 firms Your measure
of rigidity was based on number of organizational authority levels and the degree
to which written organizational rules existed and defined role behaviors for
employees Thus an organization with a large number of organizational levels
and specific written policies defining appropriate role behaviors for employees
would score high on rigidity of organizational structure After analyzing your
data you find that there is a statistically significant negative correlation between
commitment and rigidity which is consistent with your hypothesis However the
reliabilities for your two measures are
(1) commitment = 23 (2) rigidity = 83
How should you interpret your results What could you do to fix this situation
Describe the specific steps (in order) you would follow to develop a more
reliable measure of commitment

challenges in terms of designing the research measuring variables and collecting
and analyzing the data Assume that you are interested in aggregating data (eg

Organizational climate is operationalized as a shared consensual aspect of the
organization -- the shared perception among employees that the organization values
and supports continuous learning Describe how you would measure organizational
climate in this case Specify (a) the level (ie individual group organization) at
which the construct exists (b) the level at which you would measure the construct
and (c) the procedures that you would use to establish that measurement is aligned
with theory (ie the construct validity of the measure)
E) General (Measurement)
E1 Studies in organizational behavior research often rely on single-item measures of
key constructs The use of single-item measures has long been criticized based
on the premise that single-item measures are unreliable However Wanous
(Wanous amp Hudy 2001 Wanous amp Reichers 1996 Wanous Reichers amp Hudy
1997) has recently argued that single-item measures can exhibit adequate
reliability Wanous based this conclusion on a procedure for estimating the
reliability of single-item measures using the classic formula for correction for
attenuation Subsequent studies have yielded mixed results regarding the
conclusions of Wanous (eg Loo amp Kells 1998 Nagy 2002) and the veracity
of the perspective advocated by Wanous remains in question Summarize and
assess the arguments for and against the use of single-item measures and
evaluate the procedure and evidence offered by Wanous regarding the reliability
of single-item measures Based on your assessment and evaluation develop
recommendations regarding the use of single-item measures in organizational
behavior research

E2 Ipsative measures have become prevalent in organizational behavior research
Ipsative measures ask respondents to answer questions relative to one another
such that the scores for all questions sum to the same constant for all respondents
Examples of ipsative measures include rankings Q-sorts and the allocation of a
fixed number of points (eg 100) across a set of response options Ipsative
measures may be contrasted with absolute measures which ask respondents to
answer questions independently from one another Absolute measures are
exemplified by rating scales using an interval or ratio numeric response format
The relative merits of ipsative and absolute measures have been debated for
decades (eg Cornwell amp Dunlap 1994 Hicks 1970 Johnson Wood amp
Blinkhorn 1988 Saville amp Wilson 1991 1992) yet the fundamental issues
underlying this debate have not been adequately addressed in organizational
behavior research For example measures of organizational culture and values
are often ipsative and some researchers advocate these measures over absolute
measures (eg Meglino amp Ravlin 1987 OReilly Chatman amp Caldwell 1991
Ravlin amp Meglino 1987 see also Rokeach amp Ball-Rokeach 1989) Review the
relative merits of absolute and ipsative measures Based on your review which
form of measurement is most appropriate and why Do your conclusions depend
on the construct being measured If so what types of constructs are best suited to
ipsative measures and what types are best suited to absolute measures Next
apply your conclusions to the measurement of culture and values in
organizations What specific arguments have been advanced in favor of ipsative
measures of culture and values How sound are these arguments Should ipsative
measures be used in the study of organizational culture and values If not how
can absolute measures of culture and values be developed that address the
concerns voiced by advocates of ipsative measures Provide a specific example
of the type of measure you would propose

facets of a concept Although such measures are prevalent and in some cases are

and methodological problems Describe the specific problems associated with
measures that use items representing different facets of a concept Compare these
problems with the purported advantages of such measures Conclude by

E5 Suppose Roberta Von Eisenbrick is a researcher interested in the consequences of
AFFECTIVE CONFLICT (AC) in decision-making teams She gets access to a
variety of outcomes assessment committees at each of 87 different schools in
the Dallas Independent School District and gains permission to tape-record two
of their meetings (one in February and one in March) Such committees have
been formed to develop quantitative ways to track pursuit of school goals and
provide accountability to local and state governments These are often divisive
teams with heated meetings because what gets assessed is what usually gets
rewarded After both of these meetings the committee members each
fill out a short questionnaire that contains 20 Likert-type items measuring how
much AC occurred (eg People in our group often get angry with each other)
The individual scores are summed across items then averaged across team
members to come up with a group-level AC score for each of the 87 2
meetings The same procedures are followed for a 5-item measure of Group
Cohesiveness (GC) which is predicted to be reduced by higher levels of AC
Roberta also listens to every tape and from her expert judgment she rates each
groups meetings on the same 20 items Those 20 ratings are summed for each of
the 87 2 meetings Now Roberta is interested in evaluating her measure She
wants it to have excellent psychometric properties including reliability and
construct validity

D) ModeratorsMediators
D1 Moderation and mediation provide different ways to model third variable effects
(a) Please define both of these terms (b) Sketch a conceptual model to show how
each relates to main effects (c) Using variables of your choice please write
hypotheses to reflect both (d) Explain how each is tested analytically
D2 Discuss moderators and mediators Provide an example of how (1) a moderating
variable influences the relationship between the independent and dependent
variable and how (2) a mediating variable influences the relationship between
the independent and dependent variable Describe how you would test for both
moderation and mediation using regression
D3 Many theories in organizational research predict that the effects of one variable
on another are moderated by a third variable Such moderator effects are
typically tested by entering the product of two variables as a predictor after
controlling for the two variables that constitute the product Several researchers
have pointed out that this product is often highly correlated with the squares of
the two constituent variables and have suggested that moderating effects may be
tested after controlling not only for the two constituent variables but also their
squares (eg Cortina 1993 Ganzach 1998 Lubinski amp Humphreys 1990
MacCallum amp Mar 1995) Discuss the strengths and weaknesses of this
approach as compared to methods that use only the product term and its
constituent variables Conclude with recommendations as to when and under
what conditions organizational researchers should test moderator effects with the
squares of the constituent variables in the equation

D4 Assume you are interested in studying relationships amongst three variables X
Y and Z Your first hypothesis posits Z as a mediator of the relationship between
X and Y Your second hypothesis posits Z as a moderator of the relationship
between X and Y Draw the figures depicting each of these hypothesized
relationships and describe (make sure to write regression equations) how you
would test each of these hypotheses
D5 The amount of time and effort that the average person pours into his or her job
has risen steadily over the last two decades such that the average person now is
working one more week per year than the average person in the mid 1970s This
steady increase has fueled research interest in the construct of Job Burnout (JB)
which is an emotional and physical exhaustion associated with ones work
Organizational Stress (OS) the perception of greater demands than available
resources in ones work environment is thought to be one of the chief
antecedents of JB However time spent under OS is thought to make its affects
on JB accumulate or worsen Work Role Withdrawal (WRW) the avoidance of
responsibilities or the deliberate reduction of inputs to ones job is believed to be
the chief consequence of JB
a Formally state these ideas as verbal hypotheses as equations and as a complex
directed graph (circle amp arrow diagram)
b Conceptually what is a mediator Define the term and identify the mediator in
your hypotheses in (a) What elements or steps in a study design (not statistics)
that would be helpful for detecting the mediating relationship that was proposed

subdomains of management Further demonstrate your understanding of
moderator variables by picking which variable in (a) is the moderator Show the
moderating relationship in an X-Y (or multi-layered) chart Again what elements
or steps in a study design (not statistics) would be helpful for detecting the
moderating effect implied above

recommendations You conduct a well-designed controlled study (details are unimportant) and discover students who use the new book perform 10 better on a standardized subject
matter exam than those using the old book (p = 027) Both books are readily availabe their prices are almost identical and both are equally acceptable to the instructors What is your recommendation to the chair
F1 Attached is the beginning of an article Your task is to write the results section by

reader understand the results of the statistical tests you report and the nature of your
sample (Hint this can be presented in the form of a table)
2 describing and defending your choice of appropriate statistical tests of the
hypotheses and the steps that you would go through in carrying out these tests
3 making up and reporting results of these tests that are consistent with your
descriptive statistics and with any information in the rest of the article about the
results found (Hint this can be presented in the form of a table)

may want to note any relevant threats to validity here
Be sure to state any assumptions you make
F2 Assume that the Personnel Manager of a local firm Ms B dFlandres hired you to
analyze some data that her assistants had collected over the past several years The
data consist of (a) job performance ratings that were made in June of 1990 and (b)
scores on 25 predictor variables (eg measures of education job experience job
tenure job aptitude personality) that were measured when the individuals were hired
(between April 1987 and May 1988) She had data from only the 110 subjects (60
males and 50 females) who were hired during the period and were still employed by
the firm One objective of your analysis (analyses) is to determine how well the
performance criterion can be predicted by the predictors What strategy would you
use in analyzing the data Describeexplain (b) Is sample size an issue for your
analyses Explain If it is what will you do to deal with problems stemming from
sample size Assume that no additional data can be collected at this time (c) Some
preliminary analyses that you do reveal that five of the predictor variables correlate
(zero-order basis) about 75 with one another Will this influence the analyses that
you use Will it influence the validity of conclusions derived from your proposed
analyses (d) Ms dFlandres is interested in knowing if the predictor variables are
equally effective in predicting the job success of males and females What analysis
or analyses would you do to deal with this issue
F3 Assume that you have been provided with data on 12 conceptually distinct variables
that are moderately correlated with one another at the empirical level The data are
from students in four different college majors ie astronomy (A) biology (B)
criminology (C) and demography (D) The 12 measured variables fall into the
general categories of mental health (tension emotional withdrawal hallucinations
guilt feelings blunted affect and suspiciousness) and job satisfaction (work itself
supervision co-workers pay promotion prospects and working conditions) Your
task is to determine if the individuals in the four college majors differ from one
another on the 12 measured variables
(a) What statistical technique(s) would you use to test for group differences
Explain Be specific about the procedures(s) that you would use
(b) What statistical estimate would you use to estimate the extent to which the
groups differ from one another Be specific
F4 The following statistical table published in a recent issue of Work amp Occupations
was taken from an article discussing variables influencing resistance and citizenship
behaviors in the workplace Resistance behaviors include playing dumb withholding
effort work avoidance subverting particular managers and sabotage Citizenship
behaviors include cooperation engaging in peer training use of insider knowledge to
facilitate production commitment to organizational goals giving extra effort freely
Both measures are global constructs aggregated to the interval level and
standardized
The table reports the results of a series of ordinary least squares regression equations
with standardized coefficients Explain the meaning of the statistics presented What
do these statistics tell us generally about the relationship between resistance
behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows
Anomie Index -standardized interval level measure tapping multiple dimensions
The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)
F5 Researchers collected data from a sample of 350 companies on the following
variables
size (measured as number of employees)
Business Strategy (a nominal variable with 2 response options low-cost provider or
differentiator)
HR Strategy (a nominal variable with 2 response categories High commitment or
low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

statistical method not on the pedagogy of the tutorial)
I) ANOVA
I1 ANOVA Assume that you have conducted a laboratory experiment in which there
were 3 levels of Factor A (a1 a2 a3) and two levels of Factor B (b1 b2) Assume also
that there were 20 subjects in each cell
(a) Prepare a standard analysis of variance (ANOVA) table that is appropriate for this
design Make certain that you specify all effects and the appropriate degrees of
freedom for each effect If you use any abbreviations in your table make certain that
you specify their meaning
(b) Assume that an initial ANOVA analysis found no evidence of an A X B
interaction What if anything would you do with the sum of squares for the
interaction effect
I2 A study examined the effects of gender and pre-training motivation on the transfer of
training in terms of improved performance for 123 new industrial managers The
training was on supervisory skills and the dependent variable was based on the
appraisal of the supervisors performance before the training and three months after
the training The performance appraisal data were collected for research purposes
only and resulted in a total transfer score from 1 to 25 with 1 being low Pre-training
motivation was based on a 12 item Likert scale with an alpha of 86 Two groups
were identified for the pre-training motivation variable - the bottom 13 (low) and the
top 13 (high) Table 1 contains the ANOVA results and Table 2 contains the cell

mirrors Explain both sides of the debate and then lay out the role of meta-analysis
as you see it within the time span of your career as an academic To do this use
examples of already written (or yet to be written) articles as models
J5 A frequent criticism of non-quantitative research summaries (literature reviews) is
that researchers do not carefully examine how particular research designs might have
affected the statistical outcomes of the studies included in the literature review Meta-
analysis however allows one to statistically examine such effects Assume you are
conducting a meta-analysis of the relationship between leader behaviors and group
productivity Briefly describe the steps you would take in conducting a meta-
analysis What aspects of the original research designs would you examine in your
meta-analysis What steps would you take in gathering and coding data to enhance
the credibility of your analysis
K) MTMM

measures is the multi-trait multi-method matrix developed by Campbell and
Fiske (1959) Briefly describe how this matrix is obtained or constructed by a
researcher and then describe how each of the elements of the matrix is used to
demonstrate the reliability andor construct validity of the measure(s)

O4 Describe the differences between exploratory factor analysis (EFA) and
confirmatory factor analysis (CFA) When would you use one verses another
Are there ways to use EFA in a confirmatory way Can you use CFA in an
exploratory way Also describe the difference in principal components analysis
(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression
O6 The basic factor analysis model can be represented by the matrix algebraic
equation A B = C

information in each matrix and its purpose
(2) For what purpose do researchers use factor analysis Explain In the process
provide a very brief description of a study for which factor analysis would be a
useful data analytic technique
O7 Factor analysis is an important statistical technique in organizational research

c the type of quantitative output that results from applying the technique
d how a researcher would use the output in his or her research

f the important issues and problems in using the technique
P) Structural Equation Models
P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

parameter estimate bias in structural equation modeling Structural Equation

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)
Please comment on these restrictions versus access argument Which side do you
take
What are the strengths of SEM Give some examples
What are the weaknesses of SEM Give some examples

B1 Choose a model from the Organizational Behavior literature that has causal
orderings between variables and has been tested in a field setting Compare the
following data analytic methods for testing hypotheses about causality between
variable sets (eg dependent independent intervening moderating exogenous
endogenous)
a) path analysis using hierarchical regression
b) maximum likelihood estimates of structural equations models (perhaps through
LISREL)
Your answer should address
1 The parameters the procedures estimate and how they are estimated
2 How the validity of the models are judged
3 Appropriate inferences of causality and conditions necessary to make such
inferences
4 The statistical assumptions underlying each technique and the consequences of
violating assumptions
B2 Describe the critical-realist perspective of Cook and Campbell (1979) Compare and
contrast this perspective on causality with that of Poppers falsificationism
B3 According to Cook and Campbell (1979) causal relationships in the social sciences
can be probabilistic and still meet the assumption of causality that asserts that a
cause must always produce an effect Describe the logic they invoke to justify this
position
B4 Identify James Mulaik amp Bretts (1982) conditions for establishing causal
inference Discuss what they mean and why they are important to causal inference
B5 What are the three conditions necessary to establish causality Can these conditions
ever be fully met Why or why not
B6 Assume you are interested in conducting a study that allows you to legitimately
make some causal inferences concerning relationships among a set of constructs
What sorts of things can you as the researcher do to bolster your ability to make
such causal inferences In answering this question be sure to pay attention to issues
pertaining to both study design and data analysis
B7 Some researchers (and editorsreviewers) are very critical about the ease with which
others use causal language in interpreting their analyses What are the concerns
behind this criticism and what are the methodological and statistical conditions that
give rise to these concerns Under what conditions can researcher make reasonable
valid causal interpretations of their findings Can a researcher ever be completely
confident making such causal statements Be sure to defend your position in
answering these questions
C) Theory amp Research
C1 What are the elements of a theory What criteria did Bacharach (1989) use to
evaluate if a theory is good
IC
C2 The Academy of Management Journal in its Information for Contributors
states All articles published in the Journal must make a strong theoretical
contribution Because this is one of our top publications we must have a clear
understanding of what constitutes a strong theory Describe the essential elements
of a good theory You can also describe practices that are not indicative of good
theory if that will help you articulate what is good theory
C3 Organizational researchers place a high premium on research that is guided by
theory This perspective is evident in journals such as AMJ and ASQ which will
often reject a manuscript that describes a sound empirical study but does not
provide a theoretical contribution Is there a role for atheoretical research in the
organizational sciences If so what is the role of atheoretical research and what
contribution does it make to knowledge in the organizational sciences
TH
C4 Define inductive and deductive methods for generating knowledge What are the
advantages and disadvantages of each Under what conditions is each
appropriate
C5 Daft (1985) in Why I Recommended That Your Manuscript Be Rejected and
What You Can Do About It said that poor theoretical development is the
primary reason he recommended manuscripts be rejected when reviewing for
AMJ and ASQ
Why is theory considered so important
Give an example of a good theory and explain the elements that make it a strong
theory (Focus on theory development not on the content of the specific theory)
C6 You have undoubtedly heard the criticism of certain published articles in our
field being atheoretical Spoken as a criticism it suggests that research articles
should have theory Should every empirical article have theory Why is theory
important What are the hallmarks of good theory
2 RESEARCH DESIGN
A) Research Design Terms
5) Define internal and external validity Which is more important and why (It is not okay to
say they are equally important)
A1 Define (and discuss important features or issues concerning) the following
constructs of research design (Define any five terms)
1 Internal validity 6 Quasi-experimental
design
2 Stratified Sampling 7 Random Assignment
3 Solomon Four-group
design 8 Differential mortality
4 Factorial design 9 Demand
characteristic
5 External validity 10 Regression to the
mean
B) Level of Analysis
B1 IO psychologists have traditionally categorized themselves as being more micro or
macro in orientation usually falling toward the micro end Recent concern for what
has been termed the levels of analysis or cross-level approach has added a third
category - meso What is the meso level Is this just academic hairsplitting or re-
naming or is there a fundamental difference in this research strategy in contrast to
micro or macro Provide an example from some research domain of interest to you
that illustrates your conclusion of no real difference or important difference
C) Cross-Sectional vs Longitudinal Design
13) What are the benefits of a longitudinal design over a cross-sectional design in a non
experimental (correlational) study What are the disadvantages Why donrsquot we see
more longitudinal research
C1 The use of cross-sectional research designs continues despite many calls for
replacing them with longitudinal designs (a) What are the main strengths of
cross-sectional designs (b) What weaknesses do they have that longitudinal
designs supposedly counter (c) What are the implications of cross-sectional
designs for theory development (Consider internal and external validity)
C2 A good number of research efforts on the micro (OBHR) side rely on cross-
sectional designs in which surveys are used to collect both IVs and DVs from the
same respondent What are the various problems associated with such a design
What changes could be made to this design to alleviate andor eliminate these
problems What are the downsides of the new design (add in conveniencenon
probability samples)
C3 What are some of the major strengths of a longitudinal design Why dont we see
more of them
C4 Assume that you are analyzing a large sample of longitudinal survey data TH
Identify two characteristics of your data that would make ordinary least squares
regression (OLS) inappropriate for conducting analyses For each of these
characteristics describe an alternative analysis that is superior to OLS
D) Qualitative vs Quantitative Designs
D1 Compare and contrast the objectives strengths and weaknesses of
qualitativeobservational methods (eg ethnography) versus quantitative methods
(eg survey) in conducting empirical research on macro organizational issues Be
sure to consider issues of reliability generalizability validity ethics and
practicality in your answer Describe situations where one method or the other
may be most appropriate
IC
D2 In recent years a number of individuals have taken the position that qualitative
research is superior to quantitative research a Compared with quantitative
research what are the principal strengths of qualitative research b Compared
with quantitative research what are the principal weaknesses of qualitative
research
E) Observation vs Experiment
E1 Compare and contrast the objectives strengths and weaknesses of observational
methods (eg ethnographic methodology) and experimental methods Be sure to
consider issues of precision generalizability and realism in your answer Consider
also situations where one methodology or the other might be most appropriate
F) Laboratory vs Field Research
F1 Of the various research approaches available to organizational researchers
laboratory experiments are held up as an ideal because of their potential for high
internal validity On the other hand field research including participant observation
and field experiments have high potential for external validity Discuss specifically
the strengths and weaknesses of laboratory versus field experiments How would
positivist researchers think differently about these tradeoffs than would
phenomenologists
F2 In conducting an experiment in the laboratory or designing survey research there are
certain unique opportunities and limitations of each research strategy A) Describe a
hypothesized relationship between two constructs an independent and a dependent
variable in a substantive area of your choice (eg Strategy OB HRM
Organizational Theory) provide a verbal mathematical and graphical statement of
that hypothesis B) Briefly discuss how you would examine this hypothesized
relationship in a laboratory using experimental techniques versus a field survey using
correlation techniques C) Discuss what may be considered typical strengths and
weaknesses of each strategy regarding issues of precision and control in the
manipulation or measurement of the variables of interest realism of the context for
the participants and generalizability of the findings to other elements of a chosen
population D) Finally discuss advantages if any of using laboratory and field
survey methods in tandem
G) Experimental Design
2) A colleague suggests to you that only true experiments can provide useful results in
science Why might she say this What would you offer as a defense for the role of quasi-
experimental and non experimental designs in the context of the social science In
answering this question make sure you identify the defining characteristics of each design
type
9) Why and when should we be concerned about non response in research What are the
things we can do to try and decrease non response (or increase response rates)
11) Why might a researcher choose to utilize an experimental design that incorporates pretest
measure on the DV
G1 Experimental designs oftentimes come under attack due to perceived limitations in
external validity (a) Relative to other design types what strengths and weaknesses
do they offer (b) What experimental design structure is the strongest Why (c)
What is the relevance of research design for results and theory development
G2 Meta-analysts often investigate whether the quality of research design (eg
randomized experiments vs non-randomized designs) influences average effect
size In their meta-meta analysis of psychological educational and behavioral
treatments Lipsey and Wilson (1993) found that In a given treatment area poor
design or low methodological quality may result in a treatment estimate quite
discrepant from what a better quality design would yield but it is almost as likely
to be an underestimate as an overestimate (p1193) A few methodologists (eg
Shadish) have attempted to identify factors that may explain the relative magnitude
of effect sizes from randomized and nonrandomized experiments Please review
these findings and add your tentative model of the conditions under which random
experiments will produce larger smaller or equal effect sizes relative to
nonrandom designs Discuss possible implications for research design in the
context of real-world interventions
G3 Analysis of covariance and randomized blocks designs are sometimes referred to as
noise-blocking designs Explain what this means and give an example of (a) a
randomized blocks experiment and (b) an analysis of covariance experiment Keep
your examples simple Describe how such designs are noise-blocking when used
with randomized assignment of subjects to experimental condition and contrast
that with the role such designs serve in quasi-experimental designs
G4 Team performance in Bafko Industries varies considerably across teams and from
month to month The senior VP in charge of team development thought that a team
training program could improve the performance of these teams A consultant
convinced him that his firms training program which lasted only one week and
cost only $25000 per team) could raise the performance of Bafkos teams The VP
however wanted to experimentally test the efficacy of this training program before
he adopted it widely throughout the firm So the consultant suggested the following
experimental test
There were 48 teams in Bafko that showed significant variation from month to
month in their level of performance The consultant chose the 24 worst performing
teams based on last months data and assigned them to the training group After
all he argued these were the ones who most needed it The other teams were
assigned to the control group The training group received the training program
(lasting one week) at the beginning of the next month while the control group
teams did their normal routine Performance scores were gathered at the end of the
month The results showed that the training group teams had a significantly larger
rise (ie statistically significant) in their performance than did the control group
teams (who as a group did not improve at all) The consultant proudly displayed
these results and argued that they convincingly demonstrated the efficacy of his
program
How would you advise the VP Specifically what is the validity of the consultants
conclusions If you think he might be mistaken what specific threats to internal
validity are particularly plausible
G5 Consider the following design
N O Xa O
N O Xb O
N O Xc O
N O O where
Xa Xb and Xc represent different levels of a training program that varied in its
length across three different work groups In group a the training time was 40
hours in group b it was 30 hours and in state c it was 20 hours The training was
designed to instill customer service values in the team members O represents a
measure of customer service attitudes measured with a 20-item Likert scale This
measure was administered one week before the training program and 3 months
later The researcher hypothesized that the training program would improve
customer service attitudes and that longer training would have stronger effects
The design is a non-equivalent groups design because people were not randomly
assigned to groups even though groups were randomly assigned to treatment
condition Each group has a sample size of 36 members The reliability of the
customer service attitude scale was 78 at the pretest and 80 at the posttest The
pretest means were as follows
Group A 26
Group B 23
Group C 27
Control Group 25
a Construct a regression model that will test the researchers hypothesis Be
explicit here describing each variable in the model and what regression effect(s)
you would expect to find if the hypothesis were correct (Hint everything you need
to know is in Trochims chapter 11 and what we discussed in class) (10 points)
b Describe any serious threats to internal validity (10 points)
c Discuss how you might amend this design to improve its internal validity(10
points)
G6 Often in organizational research the researcher is faced with having only one group
on which to experiment and thus cannot use a control group when conducting
experiments This occurs for example in taxation experiments when you cannot
selectively apply new tax laws to different groups or when you wish to test the
efficacy of an incentive plan that must be applied to all members of a company In
such situations the researcher must be creative in assembling a quasi-experimental
design that has high validity (and usually the challenge concerns internal validity)
Consider the following scenario
A manager of a retail store wants to test the efficacy of an incentive program in
changing the selling behaviors of her retail sales clerks Specifically she wants to
test a behavioral reinforcement program in which sales peoples behavior is
recorded on in-store video cameras The tapes are analyzed each night and the
experimenter tabulates the frequency of various behaviors (eg offering assistance
to customers restocking items straightening up displays suggesting accessory
items to accompany the items that a customer is purchasing) The manager then
rewards the clerks with a monetary bonus based on the frequency of desired
behaviors She would like to conduct a valid experiment to see what effect such an
incentive program has on employee behavior but because of concerns about
employee morale she cannot assign clerks to treatment and control groups Instead
she has to apply the experimental treatment to everyone in the store She learned in
her research methods class (which the company requires all its managers to take)
that a single group experimental design typically has very low internal validity
Your job as a consultant is to help her design an experiment given her constraints
that would produce interpretable (ie internally valid) results Describe the details
of the design you would recommend using the notation in Trochim (2001) If the
design you come up with has a specific name use it As part of describing your
design discuss how the data would be analyzed and what particular effect you
would look for
G7 Why are experimental research designs held in such high regard
G8 Compare and contrast experimental quasi-experimental and correlational research
designs What characteristics separate these three designs What are their
advantages and disadvantages especially in comparison to one another
G9 What is the difference between a within-subjects experimental design and a
between-subjects experimental design When might a within-subjects design be
appropriate When might it be inappropriate
G10 Describe the difference between a basic within subjects and between subjects
experimental design What are the advantages and disadvantages of each
especially in comparison to one another Give an example from your area of
research in which each would be appropriate
G11 What are the major threats to the internal validity of a pretest - post test
nonequivalent control group design How can this design be improved with regard
to increasing a researchers ability to make causal inferences
G12 A production manager is interested in testing the hypotheses that participation in
quality circle programs will result in increased productivity and reduced
absenteeism A questionnaire is administered to a group of 92 employees
concerning their attitudes toward such programs and 46 with the most favorable
attitudes who are willing to participate are selected for the treatment group The
remaining 46 are the control group Measures of performance (unitsmonth for the
group) and absenteeism (lost daysmonth for the group) are kept over a three month
period during which the treatment group has weekly quality circle meetings The
results are as follows
Month 1 Month 2 Month 3 Month 1 Month 2 Month 3
Performance Absenteeism
Treatment 100 115 121 6 9 4
Control 110 108 113 6 8 5
The manager calculates t tests between month 1 and 3 The only significant
difference is performance for the treatment group so the manager concludes that
quality circles raise productivity but do not have an effect on absenteeism What
are the primary threats to internal and external validity in this study What are
possible alternative explanations for the differences (or lack of differences)
between the two groups What additional information might help explain these
results
G13 One stream of current strategy research contains event studies In these studies
investigators basically correlate the reaction of a financial market to the presence
andor absence of the occurrence of some event at a firm (eg the resignation of a
CEO) In a different approach to such a study suppose that one investigator (Jean)
conducts a natural field experiment on the effects of competitor mergers on a
firms environmental scanning activity Through previous arrangement Jean has
been working with 5 medium-sized computer hardware and 5 medium- sized
software firms on the west coast Shes been collecting a paper trail of internal
memos reports and phone calls that might measure environmental scanning
activity Shes been finding that the firms in both industries do about the same
amount of scanning (no significant differences) However in the midst of her data
collection Norton announces a merger with Symantec (software) A year later
Jean compares the amount of post-merger environmental scanning in the software
industry with that in hardware industry Just as Jean had hypothesized a t-test
shows a greater amount of post-merger scanning among the software firms She
concludes that her hypothesis was supported mergers of competitors cause an
increase in scanning
Critique the study described above in terms of its design flaws Identify the design
Jean used Briefly allude to problems the study has with external validity but
concentrate on the Cook and Campbell threats to internal validity Provide a
rationale for why each threat is or isnt operating in the study Link each of the
relevant threats to the specific constructs being studied (mergers and environmental
scanning) Finally do a summary evaluation -- what can be learned from this
study
H) Quasi-Experimental Design
H1 The University of Mississippi observed that the graduation rate of students with poor
grades during their freshman year was much lower than those with better grades
Wanting to improve the chances of these low performing students they tested the
effects of a new rule for freshmen The rule stated the following At the end of their
first semester all students with a GPA between 200 and 225 must register for
EDUC 1003 during their second semester Students with a GPA lower than 200
were put on academic probation EDUC 1003 consisted of a course whose objective
was to help students develop good study skills The theory was that poor study skills
were a significant cause of poor academic performance and that study skills could
be learned
They wanted to evaluate the effectiveness of this intervention so they collected data
on the GPAs of students beginning with their first semester and continuing through
to their third semester At that point they wanted to analyze the data to determine
whether the new rule was making a significant difference in the students academic
performance
What is the best way to analyze these data to reach an interpretable conclusion
Describe your approach and then discuss the major threats to validity that it has
Their sample size of students was as follows
Total N= 3454 (these are students who completed all 3 semesters)
Number of students with first semester grades between 200 and 225 (and thus took
EDUC 1003) was 956
H2 A nationwide furniture company wants to determine if a diversity training
program will improve individual sales performance on the floors of its urban retail
outlets A group of 45 salespeople in one city were given two weeks of training
Measures of individual sales performance were taken once two months prior to the
program and once two months after Forty-five salespeople (who did not receive the
training) in a similar city had the same measures taken at approximately the same
points in time The training group increased their average weekly sales from $14000
to $16500 while the non-training group improved theirs from $13000 to $14500
The change for the training group is statistically significant the change for the non-
training group is not
How would the interpretation of these results in this quasi-experimental design
differ from a true experimental design What are the threats to internal validity in
the above study and how might they be operating (be specific) What additional
information and analyses would be useful in controlling for these threats
H3 An accounting firm is interested in determining if a re-training program will reduce
errors made by its audit teams A group of 45 auditors in the home office location
are given two weeks of re-training Measures of the frequency of detectable errors
are taken once two months prior to the program and once two months after Forty-
five auditors in similar office at a branch location have similar measures taken at
approximately the same points in time The training group reduced their average
number of errors per audit from 8 to 3 while the non-training group reduced theirs
from 11 to 9 The change for the training group is statistically significant the change
for the non-training group is not
How would the interpretation of these results in this quasi-experimental design
differ from a true experimental design What are the threats to internal validity in
the above study and how might they be operating (be specific) What additional
information and analyses would be useful in controlling for these threats
H4 Describe the main classes of threats to validity that are found in quasi-experimental
research designs
H5 Dr Delta an organizational development consultant was hired by a firm that has
600 pizza parlors nationwide to assist in implementing organizational changes that
he hopes will result in higher levels of job involvement At the outset of the study
subjects had jobs with very low levels of enrichment and were paid on an hourly
basis He designed an experiment in which stores were randomly assigned to one of
three treatment conditions Condition 1 subjects experienced job enrichment (JE)
and a change to performance-based pay (PBP) Condition 2 subjects experienced
only JE and Condition 3 subjects experienced only PBP The parlors were
sufficiently far apart from one another and communication among the parlors so
poor that subjects in any parlor were totally unaware of changes made in other
parlors At the end of 18 months he measured the job involvement levels of workers
and then tested for differences between the three conditions using a standard one-
way analysis of variance In view of Dr Deltas design answer the following
questions
How sound is Dr Deltas design Comment on the weaknesses of the design
I) Interrupted Time Series Design
I1 What threats to internal validity are and are not ruled out by an interrupted time series
design that includes the introduction of a treatment and its removal at a subsequent
time period List and explain In the process be certain that you provide a diagram
that illustrates such a design
J) Validity Some Questions are about the validity of a measure others about experimental validity)
10) Identify four threats to internal validity and briefly describe what they mean
J1 It was some time ago that the tripartite view of validity was abandoned in favor of a
unitarian view in which different evidentiary bases for validity might be put forward
Binning amp Barrett (1989) represent an attempt to place multiple evidentiary bases into a
single framework Cook amp Campbell (1979) describe four aspects of validity but they
arent really meant to represent evidentiary bases Adding to the confusion is the fact
that while Binning amp Barrett and Cook amp Campbell use some of the same terms these
two pairs of authors clearly mean different things by these terms and intend for them to
be used in different ways Your task is to 1) Describe the evidentiary bases discussed
by Binning amp Barrett 2) Describe the aspects of validity described by Cook amp
Campbell 3) Describe the similarities and differences between the two lists including
the different purposes served by the two lists and 4) Present a single framework that
incorporates both This last task is the most important of the four
J2 What are the types of validity How would each affect an empirical study IC
J3 Define both internal and external validity Which is more important (it is not okay to
say that they are equally important) Defend your reasoning
J4 Why might someone argue that the construct validity of a measure can never really be
established
J5 Describe each of the following forms of validity content convergent discriminant
criterion-related and construct How is each assessed How do they related to each
other Which is most important (Make sure you defend your answer)
J6 Define and explain 6 of the 8 types of validity listed below and describe the type(s) of
information each provides Choose one specific type of study as an example (eg
cross-sectional study experiment quasi-experiment simulation ethnography etc) and
compare and contrast the usefulness and importance of each type of validity for that
type of study
-- Concurrent validity
-- Construct validity
-- Content validity
-- Convergent validity
-- Discriminant validity
-- Statistical conclusion validity
-- Internal validity
-- External validity
J7 Designing empirical research has been called making a series of trade-offs
Unfortunately decisions that are made to increase one desired quality (like internal
validity) can also decrease another desired quality (like external validity) For each of
the issues below discuss the concerns involved (ie the trade-off) and identify the
qualities that are being increased or decreased
a laboratory vs field study
b using a 5-item measure vs a 1-item measure
c using a student sample vs a sample of full-time employees
d using a sample of employees from one company of 5000 vs 500 employees from
each of 10 companies
e collecting your data using one method vs collecting your data using multiple
methods
J8 There are four major types of validity in social science internal validity external
validity construct validity and statistical conclusion validity Please address the
following three issues concerning validity
a What is the meaning of the four major forms of validity (ie internal and external
validity construct validity statistical conclusion validity)
b Are there trade-offs that can or must be made among the four types of validity
d Describe how the concept of validity varies across the research traditions of
experimental vs observational research
IC
J9 The quality of research is often assessed by examining validity issues As you are
aware there are numerous typesforms of validity (eg internal and external validity
construct validity statistical conclusion validity) These types of validity address
different aspects of the research process For this question please address the following
issues
a What is the meaning of the four major forms of validity (ie internal and external
validity construct validity statistical conclusion validity)
b Should there be a priority among these forms of validity If yes why If no why not
c Does the concept of validity vary across research traditions (ie experimental vs
observational research) If yes why If no why not
J10 External validity has received considerable attention in the social and behavioral
sciences Some researchers argue we are too concerned with the external validity of our
findings while other researchers argue that we are too unconcerned with external
validity Several points of view have been developed to explain what is external
validity When answering this question please be sure to address at least the following
issues
a Compare and contrast alternative conceptualizations of external validity
b Some researchers have argued that the role of external validity is invariant across
research traditions (ie experimental vs observational research) Defend the
perspective that the role external validity is invariant across these two research
traditions In addition present the weaknesses of this perspective
J11 In designing a research study researchers must consider trade-offs between internal and
external validity Explain what is meant by internal validity and external validity What
is the nature of these trade-offs How would you evaluatedetermine which is more
important internal or external validity for a particular study Why is this such an
important issue in organizational studies
J12 A researcher conducted a quasi-experiment to test the effects of participative decision
making (PDM) on job attitudes of employees Employees from different departments in
a large organization were assigned to either a treatment group (PDM implemented) or a
control group (no PDM) Random assignment was not possible because of work
schedules coordination of tasks etc Thus the design can be considered an untreated
control group design with pretest and posttest and is represented as follows (where
O=observation X = treatment)
________________
O1 X O2
-------------------------
O1 O2
_________________
The results of the experiment are presented in the graph below [no graph provided]
The dependent variable is job satisfaction and is measured on a 100 point scale (with
100 being extremely satisfied) How amenable are these results to causal interpretation
What is (are) the major threat(s) to internal validity B if any B for this type of design
given these results What steps can be taken to assess the extent of this (these)
threat(s)
K) Data Collection Methods
14) Describe the various methods of data collection (eg survey interview observation etc)
available to a social scientist What are the advantages and disadvantages of each relative to
each other
K1 Within micro organizational research much criticism has been raised concerning
the reliance on self-report survey data What potential problems does self-report
survey research raise How big of a problem do you think this is
K2 There are a number of methods for collecting data (eg survey interview archival
etc) that are available to a social scientistorganizational researcher Discuss each in
terms of their strengths and weaknesses both on their own and in comparison to one
another
K3 Pick an important construct in your favorite area of management research for which
there is some controversy about how it should be measured or operationalized (eg
environmental munificence or growth need strength) Give the prevailing verbal
definition of the construct and analyze the measurement controversy from two
broad angles First discuss how the controversy may or may not stem from claims
about how one measure is better or worse than another because it (or the other) is an
(a) archival record (b) direct observation (c) social report or (d) self-report That is
what are the relative strengths and weaknesses of each of these types of
measurement for the construct youre discussing Second discuss the construct
validity of the most commonly used measure(s) of this construct To answer this
second part you need to discuss just what construct validity is and how it can or
cannot be demonstrated In the situation you describe what could be done to
demonstrate or improve the construct validity of existing measures
K4 Interviewing in some form has been the workhorse for data collection in a variety
of research traditions positivistquantitative ethnographic feministpost-modernist
and increasingly historical research While each tradition elicits information from
respondents the goals and processes involved in interviewing vary considerably
across research traditions Discuss the purposes of the interview the relationship
between data and theory the roles assumed by the interviewer and the respondent
and the relevant criteria for assessing the validity and reliability of the information
obtained In addition compare and contrast the use of the interview as a data
collection method in the positivistquantitative tradition with its use in one of the
alternative traditions
L) Common Method Variance
L1 Many of us have had concerns about the reviews of our survey research which
suggest that data analyses of surveys are biased because of common method
variance effects of individual differences such as negative mood negative
affectivity and social desirability and the reliability and validity of the constructs
we are attempting to measure Define how these problems affect a research issue in
organizational behavior and the steps that might be taken to minimize such potential
criticisms of papers based on analyses of self-reported data through survey
instruments
L2 In a series of papers by Spector (1994) Schmitt (1994) and Howard (1994)
published in the Journal of Organizational Behavior arguments were provided for
and against the use of self-report questionnaire measures One of the issues
discussed that could limit conclusions drawn from relationships observed using self-
report measures was method variance What is meant by method variance what are
its sources and what impact is it expected to have on research findings
M) Sampling
M1 The manufacturing census samples all plants of 250 employees or more For
plants of 5-249 employees it takes a size proportional sample Plants of 1-4
employees are not sampled What challenges does this sampling method provide
to researchers What could you do to account for these problems if you were
TH
studying organizational (not plant) growth
M2 New York State has approximately 250000 employees in over 70 state agencies
commissions and boards ranging in size from approximately 50 to over 5000
employees Assume that you wanted to draw a representative sample of 1000
employees Describe two ways that you could draw such a sample and briefly
describe the advantages and disadvantages of each of these sampling approaches
IC
M3 The director of a national non-profit agency with approximately 10000
employees located primarily in regional offices in each of the 50 states the
United States has approached you and asked you to develop a study
(organizational survey) of organizational culture within the agency The agency
is about to embark on a variety of change initiatives including developing team
structures and the study is meant to examine various elements of organizational
culture that are potential barriers to change The director has indicated that he
would like to have the data analyzed at both the individual and office level of
analysis Because of funding limitations the agency will only be able to send the
survey to 1000 employees The director has indicated that there are three ways
of sorting employees all employees listed alphabetically all employees listed
alphabetically by state and all employees listed alphabetically by region (there
are between five and ten regions per state) Given these three ways of sorting
employees describe at least three different sampling approaches and the
advantages and disadvantages of each
M4 In your role as Teacher of Organizational Studies you are asked to prepare a
tutorial for beginning doctoral students on sampling design Assume that this
tutorial is part of a basic class in research design and that students in this class
have had a basic statistics course up to and including multiple regression Your
tutorial should focus on briefly defining and explaining the differences between
probability and non-probability samples You should make sure to present and
describe several types of probability samples (eg random systematic
stratified etc) and non-probability samples (eg convenience snow-ball quota
etc) and discuss general principles for when to use a probability vs a non-
probability sampling design For each sampling design you should also provide
at least one clear example of a situation where this type of sampling design is
appropriate
N) Cross-Cultural Research
N1 Discuss the problems in conducting cross-culturalnational comparison in terms
of (1) conceptualization and (2) research design and data collection
Define the three levels of measurement invariance How would the problems that
you have identified in part (a) affect measurement invariance How would you
examine measurement invariance by confirmatory factor analysis
TH
N2 Explain why using national boundaries as independent variable in cross-cultural
studies may not be appropriate in terms of theory and research methods What
alternative ways would you recommend
IC
O) General
O1 In your readings research has been described as choices among conflicting goals
(desiderata) For instance when choosing among research strategies a researcher
must choose among the desiderata of precision realism and generalizability The
trade-offs among desiderata occur for all aspects of research that is for the selection
of theories the treatment of independent variables research strategies the selection
of the problem to study rules of evidence for determining the meaningfulness of a
research finding and even the frameworks that describe the research process
Discuss what you see as the major trade-offs for each of the following aspects of
research That is discuss what you see as the major strengths and weaknesses
(advantages and disadvantages) of each aspect
a The trade-offs between internal and external validity
b The manipulation of the independent variable vs the observation of the
independent variable
c Basic vs applied research
3 DESIGNING A RESEARCH STUDY
A) General (Research Design)
3) Why is control so important in research design What are the different ways it can be
achieved (give a brief description of each control method) What are advantages and
disadvantages of each
A1 It has become almost a truism to note that the choice of methods influences theory
and questions data and conclusions (the causal direction might also be reversed)
Briefly discuss how the methods used have influenced research in any two of the
following areas leadership power and politics organization culture organization
justice Compare and contrast as possible Suggest some potentially fruitful
methodological directions for future work in these same topical areas and dont be
shy about reflecting on broader issues of how the field of organizational behavior
constructs its realities Lastly tie your discussion and reflections back to your own
future as a researcher what lessons or guidance do you derive from your
understanding of these issues
A2 Characterize as fully as possible what you see to be the methodological approach or
approaches in strategic management research Is there a dominant method or a wide
variety Discuss the reasons for the situation What are the advantages benefits etc
of the approach(es) in use What assumptions (ontological epistemological
ideological) do they embody Are current efforts ideal or at least adequate Are
there other approaches that could be useful If so how might researchers be
encouraged to use these as well If you see no advantage to more variety in
methodological approach support that point of view
A3 Describe a research question or area of interest to you and why you think it is not
only of interest but significance Using your understanding of research methodology
describe two ways of pursing the question that are as divergent on as many
dimensions as you can imagine Describe the advantages and disadvantages of each
approach How strong a link or fit is there between a research question and a
method
A4 In his 1957 article entitled The two disciplines of scientific psychology Cronbach
discussed the assumptions goals and methods used in experimental methods and
correlational methods in psychology
a According to Cronbach what is the main difference between the two disciplines
b Discuss the strength and weaknesses of each discipline
c What if anything could be done to improve the situation
B) Designing a Research Study
B1 Cook and Campbell describe the experiment as the research design with the
greatest methodological rigor However given the constraints present in most
organizations I-O Psychologists cannot often conduct experiments in applied
settings and must settle for techniques with less control than experiments
Describe a study to investigate the relationship between participation in a
supervisor training program and work performance which could realistically be
conducted in an organization If an experiment is not possible describe how you
would go about maximizing your ability to draw valid conclusions from your
design
B2 The XYZ Co has recently developed a sexual harassment web-based training
program The developers claim the program will cut training time and costs and
will be as effective or more effective than classroom-based sessions They
believe that this will be due to the increased availability of the program and the
ability for participants to review program material on demand Before the XYZ
Co developers launch this product they want you to determine if their claims
have merit Explain how you would design a study for this purpose
B3 Research suggests that demographic diversity improves group creativity but
reduces group efficiency Some argue that demographic diversity is just a proxy
for value and experience diversity and that demographic diversity on its own is
meaningless Design a test to settle this argument
TH
B4 E-mail has become a common form of communication in organizations and is
used for both formal and informal communication Because it has become so
IC
popular some people complain that the frequent use of e-mail leads to
miscommunication because they receive communications in e-mail that should
be accomplished through face-to-face or telephone conversations where there is
an opportunity for interaction You are interested in looking at this
phenomenon You are most interested in describing how e-mail is used for both
formal and informal communication and in examining the effect of the e-mail
use on organizational communication effectiveness Design empirical research
to address those issues
Describe your study in detail thoroughly explaining the research design
sampling plan data collection procedures ethical issues and proposed data
analysis for your research design Be sure to discuss the internal and external
validity of your research Which validity threats are ruled out and which
remain
REMEMBER Be thorough Your research design should demonstrate that you
are a competent researcher who is knowledgeable about the proposed research
methodology or methodologies Therefore be sure that you carefully describe
and give technical explanations for each component of your research
B5 Choose a specific situation involving employee selection eg artists for an
advertising agency (a) What strategy would you use in selecting the selection
measures (b) How would you combine the measures eg which measures
would you combine in a compensatory manner and which is a noncompensatory
manner (c) How would you assume test fairness defining various measures of
the term (d) How would you make final selections (e) How would you
validate your procedure (f) What considerations would enter in if your
company were too small to provide validation data (g) What difference would
it make if you were developing a procedure for deciding whether trainees
should be promoted as opposed to making new hires Please note--emphasize
but do not limit yourself to statistical issues
B6 There is evidence in the marketing literature of a non-monotonic relationship
between the expectations that customers have for retail service and their
eventual level of satisfaction with that service That is as a customers
expectations for service increase so does their eventual service satisfaction --
up to a point After that point the greater the expectations the lower the
eventual satisfaction Develop a hypothesis that includes a moderator variable
that might account for this evidence Give some reasonable rationale for it State
your hypothesis verbally as an equation as a directed graph (circle amp arrow
diagram) and as an X-Y function chart Discuss how it would or would not be
possible or useful to test your hypothesis via a laboratory experiment In your
discussion cover how and why a researcher could (not) manipulate the
independent constructs involved (mode X) whether or not random assignment
to conditions (mode R) is possible (including how may conditions would be
necessary) which alternative constructs could or could not be controlled (mode
K) and which constructs should be measured (mode Y)
B7 Assume you are the chairperson of a committee that must evaluate
undergraduate programs at your university Your task as chairperson is to
devise an approach (a design a research strategy a set of measures) that will
allow you to evaluate undergraduate programs Make sure that your approach
can be used in the future and at other comparable universities When developing
your plan be sure to address at least the following issues
a the type of design you would select Compare and contrast the selected design
with another possible design
b the type of research strategy you would select Compare and contrast with
another possible strategies
c discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
B8 Assume you are an organizational research design expert assigned to the
Strategic Planning Department of a large multi-national manufacturing firm
The Department has developed a new PC-based software package called
STRATPACK The software (and a one-week training course to learn how to
use it) is intended to improve the long-range planning ability of middle and
upper-level managers
Your job as research design expert is to devise research (a design a research
strategy a set of measures) that will allow you to evaluate the effectiveness of
the STRATPACK program Describe a research design for evaluating the
program Make sure that your research approach can be used in the future and at
all sites in the company When developing your plan be sure to address at least
the following issues
a discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
b the type of design you would select (eg a design where you manipulate the
independent variable versus observe the independent variable) Compare and
contrast the selected design with another possible design
c how your design deals with the major forms of validity Be sure to examine at
least internal external and construct validity
B9 Assume you are a consultant hired to evaluate the effectiveness of an industrial
safety program undertaken by a large manufacturing organization The safety
program is a behavioral one that provides rewards such as monetary bonuses or
extra paid vacation days for safety behaviors in terms of accident-free days
weeks etc Your task is to devise an approach (a research strategy a design a
set of measures and a general analysis strategy) that will allow you to evaluate
the safety program Because of the potential for the influence of many
extraneous variables on any safety program it is difficult to design research a
single cross-sectional study than can evaluate the impact of a single safety
program How would you design a study to evaluate the impact of the safety
program When developing your plan be sure to address at least the following
issues
a the type of research strategy you would select Compare and contrast with
another possible strategies
b the type of design you would select Compare and contrast the selected design
with another possible design
c discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
B10 One of the most important areas of research is forecasting of human resources
needs based on strategic positions of organizations For example NY State must
carefully forecast its human resources needs as it proceeds with significant lay-
offs of state employees Future human resources needs are generally evaluated
by either statistical ie regression or simulation or clinical judgment i e
supervisors judgments methods
a Design a single study that addresses the empirical question of whether
statistical or judgmental methods are better for forecasting human resources
needs You may discuss a program of research but please be quite specific in
your description of the first study
b What are the critical methodological issues in doing this kind of research
c What are the critical applied (or practical) issues in doing this research
d Are the issues in b and c related
B11 In the past decade computinginformation technology has changed many
aspects of organizational life For example the technology can make increased
decentralization possible by improving communication between central offices
and field offices Computer networks and word processors can enhance group
empowerment by making it possible for team members to create and edit
written group products quickly even if the individuals are at different locations
Some have argued that computinginformation technology will foster the
paperless productive office nevertheless others argue that the technology only
increases paper and reduces office productivity You are applying to the
National Science Foundation for a grant to conduct research that examines the
impact of computing information technology on organizational decision
processes The NSF application procedure imposes five basic requirements that
your research design must fulfill in order to receive funding Note A very
significant factor affecting NSF grant decisions is a clear demonstration that the
researcher is knowledgeable about the research methodology used Write your
response to each of the following five grant requirements Be sure not only to
respond to the requirement but also to demonstrate your research
competence
1You must design a study that uses two different methods
(interviewobservation survey experiment or quasi-experiment) Describe your
two methods in detail and provide a rationale for the key elements (eg
sampling data collection proposed analysis) of your methods Be sure to
discuss and evaluate the internal and external validity of both methods
2 As part of your research design you must select a conceptual (latent) variable
central to your proposal (use centralization of decision making as your
variable) and describe how you will develop your own measure (You may not
simply use off the shelf instruments)
3 You must describe how you will test for the reliability of the measure
(centralization of decision making) you developed in step 2 The NSF insists
that you describe how you will evaluate both the temporal stability and the
internal consistency of your measure Be sure to discuss what temporal stability
and internal reliability mean and how they are related
4You must describe how you will assess the validity of the measure
(centralization of decision making) you developed in step 2
5 NSF requires a brief statement and defense of the philosophy of science
underlying your research Discuss your position and show how your research
design is consistent with your philosophy
B12 Many organizations in the United States economy have installed some form of
Empowered Teams as an alternative or supplement to traditional bureaucratic
structure Preliminary evidence of the effectiveness of empowered teams
however is mixed--some organizations have claimed success and others have
reported failures The evidence however is predominantly anecdotal--written
for trade magazines by the organizations themselves There are few rigorous
empirical studies assessing the effectiveness of empowered or self-managed
teams You are applying to the United States Department of Labor (USDOL) for
a grant to conduct research that examines the effectiveness of empowered
teams The application procedure of the USDOL imposes three requirements
that your research design must fulfill in order to receive funding Write your
response to each of the three grant requirements The importance of each section
is implied by the evaluation points allocated by the USDOL to each of the three
requirements given in parentheses
1 (50 points) Your study design for assessing Empowered Team effectiveness
must use two different methods (interview observation archival analysis
survey simulation experiment or quasi-experiment) Describe in detail and
thoroughly explain the sampling plan instrumentation data collection
procedures and proposed data analyses for both methods Be sure to discuss the
internal and external validity of both methods and how the two methods
complement one another
2 (30 points) As part of your research design you must select one conceptual
(latent) variable central to your proposal and describe how you will develop
your own operationalization of the measure (You may not simply use off the
shelf instruments) Use the concept of group morale to demonstrate your
operationalization methodology Be sure to explain very explicitly to the
USDOL how you will assess the validity and reliability of the group morale
measure you are developing
3 (20 points) The USDOL traditionally has funded research conducted only
within the general paradigm of logical positivism but now is more open to other
research paradigms as well Your grant proposal must provide a statement and
defense of the explicit philosophy of science underlying your research Describe
your philosophy of science and show how your research design is consistent
with your philosophy
REMEMBER Be thorough You not only must design effective research but
you also must demonstrate to the USDOL that you are a competent researcher
It is absolutely vital to the USDOL that the principal researcher is
knowledgeable about the proposed research methodologies Therefore be sure
that you always carefully describe and give technical explanations for each
component of your research design and explain all technical terms (eg
Cronbach alpha KR-20 Likert scale)
B13 Assume that you are working as part of a research team that is responding to a
RFP (Request for Proposals) from a funding agency for research on work
socialization and newcomer adjustment The RFP calls for rigorous field
research that tests the effectiveness of theory-based interventions aimed at
facilitating the adjustment of new organizational members to complex andor
stressful work conditions The major goal of your teams research is to test the
effectiveness of a self-regulation intervention which trains newcomers to
identify and use relevant social information and cues to regulate work behavior
Your group hypothesizes that self-regulation training will be more effective
than other common treatments or interventions (eg realistic job previews
institutionalized socialization tactics)
You have been included in the team because of your methodological expertise
Your role is to design a rigorous field experiment or quasi-experiment to test he
effectiveness of the self-regulation training program REMEMBER THE
MAJOR CRITERION FOR FUNDING IS THE RIGOR OF THE RESEARCH
DESIGN Design a field study to include in the grant proposal Your proposal
should contain the following two sections
1 Study Design Construct and describe in detail an experimental or quasi-
experimental design to test the effectiveness of your intervention Describe in
detail the experimental groups (including how they will be constructed) the
research setting the sampling plan for study participants the treatment
manipulation and the data collection procedures Also indicate any control or
nuisance variables that may be measured
After describing the procedures write a justification of the design What threats
to validity does it rule out or limit and what threats to validity remain
II Measurement Describe the steps you would take to achieve valid and
reliable measure of the latent (conceptual) variable worker adjustment Your
team feels that as part of the proposal you must develop an original
operationalization of adjustment (thus you cannot simply use existing off the
shelf measures) Indicate in adequate detail how you would operationalize the
measure and indicate how you would demonstrate reliability and validity
B14 In describing their notion of the collective mind Karl E Weick and Karlene H
Roberts note Our focus is at once on individuals and the collective since only
individuals can contribute to a collective mind but a collective mind is distinct
from an individual because it inheres in the pattern of interrelated activities
among many people (p 360) Collective mind is not indexed by within-group
similarity of attitudes ideas or activities A collective mind is one in which
many people or many groups integrate their different attitudes ideas and
activities heedfully As Weick and Roberts note People act heedfully when
they act more or less carefully critically consistently purposefully attentively
studiously vigilantly conscientiously pertinaciously (p 361)
The idea of the collective mind as heedful interrelating is developed in the
following excerpt When people make efforts to interrelate these efforts can
range from heedful to heedless The more heed reflected in a pattern of
interrelations the more developed the collective mind and the greater the
capability to comprehend unexpected events that evolve rapidly in unexpected
ways When we say that a collective mind comprehends unexpected events we
mean that heedful interrelating connects sufficient know-how to meet situational
demands For organizations concerned with reliability those developments
often consist of unexpected non-sequential interaction (p366)
An example of heedful interrelating occurs as a pilot lands herhis aircraft on the
deck of an aircraft carrier The pilot does not actually land She is recovered
A recovery is an interrelated set of activities among air traffic controllers
landing signal officers the control tower navigators deck hands the helmsman
driving the ship etc These activities can be interrelated more or less heedfully
depending on the care with which the different units contribute represent the
situation and subordinate their activities to the single purpose of successful
recovery (p 363)
You are to design a two-part study
Part I You are to design a measurement study which assesses heedful
interrelating (ie collective mind) with a quantitative measure in a replication
of an aircraft carrier flight deck or other situation of your choosing Describe
your research strategies including operationalization of the variable selection of
the sample subjects data collection data analysis and so on for the purpose of
developing a measure of heedful interrelating
Part II Using the measurement tool developed in Part I and any other tools as
needed describe how you would design a study which would compare heedful
interrelating across organizations Choose at least one macro-organizational
variable (eg technology environment) as your basis of comparison Here you
must describe how you would make your selection of organizations to be
compared your data collection procedure data analysis and so on
B15 Many organizations in the United States have installed cross-functional teams to
counteract the silo mentality of traditional bureaucratic structure Preliminary
evidence of the effectiveness of cross-functional teams however is mixed --
some organizations have claimed success and others have reported failures The
evidence moreover is predominantly anecdotal--written for trade magazines by
the organizations themselves Since there have been few rigorous empirical
field studies assessing the effectiveness of cross functional teams the National
Science Foundation has decided to fund research on the topic
Assume that you are submitting a research proposal to NSF for a grant to
research the effectiveness of cross-functional teams Describe in detail and
thoroughly explain the research design sampling plan data collection
procedures ethical issues and proposed data analysis for your research design
Be sure to discuss the internal and external validity of your research Which
validity threats are ruled out and which remain NSF also requires that you
provide a statement and defense of the explicit philosophy of science underlying
your research Describe your philosophy of science and discuss how your
research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but
you must also demonstrate to NSF that you are a competent researcher It is
absolutely vital to NSF that the principal researcher (you) is knowledgeable
about the proposed research methodologies Therefore be sure that you always
carefully describe and give technical explanations for each component of your
research design and explain all technical terms (eg Cronbach alpha KR-20
Likert scale)
B16 Assume that you are submitting a research proposal to the Department of
Commerce (DoC) for a grant to research the effectiveness of virtual work teams

geographically separate from one another and share their expertise using
internet media such as a listserver or Lotus notes The DoC requires that the
researcher use both qualitative and quantitative methods to gather data Describe
in detail and thoroughly explain the research design sampling plan data
collection procedures ethical issues and proposed data analysis for your
research design Be sure to discuss the internal and external validity of your
research Which validity threats are ruled out and which remain The DoC also

5 MEASUREMENT
A) Measurement Terms
A1 There are four levels of measurement rigor in management research Discuss each
one What properties do measurements at each level have (ie how much
information do the numbers from each level of measurement convey) How can the
numbers be changed (transformed) and still retain the properties of their
measurement level Pick one construct from a favorite research domain and give an
example of an operationalization of that construct at each of the four levels of
measurement rigor (provide arguments about why you think those examples reflect
each level) Lastly treat each examplelevel as a dependent variable in some
statistical analysis Given an example of a statistical technique appropriate for
analyzing data at that level of measurement rigor
A2 Define (and discuss important features or issues concerning) the following
constructs measurement (Define any six terms)
1 Construct validity 6 Item analysis

estate agents self-assessment of performance Since there is no existing
measurement available you have to develop the instrument by yourself
Describe how you would develop the measurement assuming that you have no
idea of how many dimension the construct has
b) Suppose you have developed an instrument consists of 20 questions
measuring 4 dimensions (5 items per dimension) from (a) You collected data
from another 300 real estate agents to validate your instrument Explain how
TH
you would use structural equations model (SEM) to examine the reliability and
validity of the instrument What are other concerns about reliability and validity
that are not addressed by this approach
B2 The research and business world have been fascinated with the concept of
organizational culture However operationalizing this construct has been a
difficult task Discuss the ways in which the construct has been operationalized
(eg technique static v dynamic sample selection generalizability) Critically
analyze each of these methodologies Then choose a methodology you would
use to examine organizational culture and defend your choice Describe how
you would study culture and what more would be known about culture as a
result of your study
B3 Suppose you are setting out to develop a new measure of a construct You want
this measure to be used in survey research and you want to establish its validity
and reliability Your goal is to have at the end of the process a measure that is
defensible and likely to be widely accepted by other researchers studying that
construct What steps would you take to conduct such a program of research
For each step explain the purpose of that step explain why that step is
important explain what methods and statistical procedures you would employ at
each step and explain what evidence you would hope to gather at each step
B4 Assume you are interested in constructing a new measure of (fill in with a
relevant variable from your field) Detail the major concerns that need to be
addressed and the steps that need to be taken in working toward validating this
new measure
B5 Assume that you recently read an article on workplace violence which you
found very interesting The authors argued that one of the predictors of
workplace violence was a construct called propensity to be violent and used a
one-item measure as follows How likely are you to become violent when
provoked You had serious doubts about the authors measure and decided to
develop your own
(a) How would you go about developing items to measure propensity to be
violent
(b) How would you determine whether the instrument was reliable
How would you determine whether the instrument was valid
B6 A concern in organizations is retirement of baby boomers within the next 5 -
10 years This concern is focused on the loss of older employees with skills
critical to the core business functions of organizations In order to continue to
have employees with those critical skills it seems necessary to retrain some
older workers However past practice in most organizations has been not to
retrain older workers for a variety of reasons mostly financial A researcher
working for the Human Resources Department of a large corporation - 13500
employees in 12 different plant locations - hypothesizes that the major reason
for not retraining older workers is ingrained in the culture of the corporation
IC
The researcher feels that older workers are not as highly valued as younger
workers in terms of their potential usefulness after retraining The researcher
searched the literature but found nothing in the existing literature to measure
the cultural value construct What should the researcher do to establish a reliable
and valid self-administered paper and pencil measure of this construct namely
the value of retraining older workers

determining the level of centrality of decision making in the organization
Describe and justify the steps you might follow to develop an operationalization
of the concept of technological complexity What standards would you use to
determine if your operationalization is valid
B8 Organizational researchers have several strategies available to them for
gathering information (eg self-report measures archival measures direct
observation and trace measures) Assume that you are going to conduct
empirical research to assess the role that the structure of the organization plays
in determining the level of organizational effectiveness Briefly review the
strengths and weaknesses of the basic strategies (that is self-report measures
archival measures direct observation and trace measures) for measuring
organizational effectiveness Next describe and justify the steps you would
take to develop an operationalization of the concept of organizational
effectiveness What standards and procedures would you use to determine if
your operationalization is valid
B9 One of the most important topics of recent research has been stress in the work
place One of the most important problems with understanding this literature is
the varying definitions and measurement of this construct Suppose you had
decided to investigate the relationship between stress at the work place and dual
career family happiness
a Since there are multiple ways to measure stress in the work place describe
two ways to do this Hint - avoid using two self-report measures
b Describe how you would decide on the best single measure In doing so
describe the steps you would take in evaluating your measure Be sure to define
your meaning of validity and reliability It is important that your measure have
all the necessary psychometric characteristics so that other scientist can trust the
results of your research
c Be certain that you answer the question Validity for what
d In order to understand the results of your study you need to compare your
measure of stress at work with other measures of this construct How would you
do that
B10 Assume that you have been hired by a national survey research company
Shash Inc to write items that will be used in a national survey of attitudes

impact of interpersonal trust on organizational decision making Describe and
justify the steps you might follow to develop an operationalization of the
interpersonal trust concept

commitment of employees Describe and justifyexplain the steps you would
follow to develop a valid and reliable operationalization of the concept of
employee empowerment
Explain the procedures and standards you would use to determine if your
operationalization is valid and reliable
How would you assess the construct validity of such a measure
Discuss issues concerning the level of observation of your measure and level of
analysis of the data
B13 Assume you are interested in developing a new scale to measure construct X
Further assume that you have used previous literature and your own conceptual
development to delineate 2 dimensions of X specifically XF1 and XF2
Describe the steps you would go through in developing testing and evaluating
this new scale With regard to testing and evaluating be sure to consider the
role of factor analysis (both exploratory and confirmatory) and item analysis
Also you will want to make sure that your new multidimensional scale shows
evidence of validity (several kinds) and reliability so be sure to examine these
issues and explain how specific information gathered from the above testing
contributes to these concerns
C) Reliability

assessed and when is each appropriate
15) What does coefficient alpha assess What are the ways coefficient alpha can be increased
C1 Describe and discuss the concept of reliability and all of its various forms
including their assessment When is each form appropriate and what information
is provided by each index
C2 In establishing congruence between multiple measurements we often compute
indices of reliability andor indices of agreement These two types of indices
address very different questions Your task is to 1) Define reliability and
agreement 2) Explain when each is useful using examples in which one but not
the other is appropriate and 3) Briefly describe two reliability indices and two
agreement indices
C3 Explain reliability in terms of the classical test theory What are the
consequences of unreliable measures in hypothesis testing What are the factors

true test score theory domain sampling theory generalizability theory IRT)
Discuss the different approaches for estimating reliability and the contexts in
which each might be appropriate Use examples throughout
C7 What are the consequences of unreliability in a measure
C8 What are some of the conditions that might keep the internal consistency (eg
alpha) of a given measure low Is a low alpha always a sign of a problematic
measure
C9 Define reliability Name some methods of calculating reliability How well do
these methods map up with the definition of reliability What is the impact of the
number of test items and sample size on Chronbachs alpha and why would this
effect occur or not occur (Note Do NOT discuss inter-rater reliability)
C10 Schmidt and Hunter (1996) described several types of measures typically used in
organizational research and identified the type(s) of measurement error affecting
each of them in various situations For each measure below indicate the types of
error and sources of error that are most likely to affect it Then indicate what
could be done to reduce errors of measurement andor what can be done to
control for errors statistically
a Supervisor ratings of subordinates job performance
b Self-ratings of ones own job performance
c Self-reports of ones own job-related attitudes
d Sales figures for a salesperson (or production quantity for a production
worker)
d Aptitude tests taken as part of the hiring process
C11 Suppose you had conducted research on the relationship between organizational
commitment and rigidity of organizational structure in 200 firms Your measure
of rigidity was based on number of organizational authority levels and the degree
to which written organizational rules existed and defined role behaviors for
employees Thus an organization with a large number of organizational levels
and specific written policies defining appropriate role behaviors for employees
would score high on rigidity of organizational structure After analyzing your
data you find that there is a statistically significant negative correlation between
commitment and rigidity which is consistent with your hypothesis However the
reliabilities for your two measures are
(1) commitment = 23 (2) rigidity = 83
How should you interpret your results What could you do to fix this situation
Describe the specific steps (in order) you would follow to develop a more
reliable measure of commitment
C12 (a) Define the concept of reliability (of measures) in a clear concise and
accurate manner (b) Provide a formula that expresses the reliability of a measure
in terms of two components of variance ie total variance and the error
variance
D) Multi-level Assessment
D1 One of the major challenges for group-level research is the issue of aggregation of
individual data to the group level
(a) Under what conditions (eg types of data number of raters) should the various
interrater agreement and reliability methods be used (Rwg Kappa and Weighted
Kappa percent agreement average pairwise correlation ANOVA methods
(interclass correlation coefficient WABA)) What are the advantages and
disadvantages of each of the methods
(b) Explain the controversy between Frank Schmidt Larry James and others
regarding the differences between interrater agreement and interrater reliability
Who is right Do the differences matter in research practice
Defend your answers
(c) Review two articles from the organizational behavior literature that have had to
deal with aggregation issues Critique the methods the authors used to make
aggregation decisions
(d) Provide some advice to researchers regarding what they should do if interrater
agreement and reliability indices indicate that it is not legitimate to aggregate their
data
(e) Provide some ideas for avoiding the need to aggregate in group-level research
through creative research methods and measurement strategies
D2 Cross-levelmulti-level research is becoming more evident in the organizational
research literature This type of research raises many issues and presents many
challenges in terms of designing the research measuring variables and collecting
and analyzing the data Assume that you are interested in aggregating data (eg
from the individual to the group or from the firm to the industry) for one or more
variables What are the major issues you will need to deal with
D3 A researcher wants to measure organizational climate for continuous learning
Organizational climate is operationalized as a shared consensual aspect of the
organization -- the shared perception among employees that the organization values
and supports continuous learning Describe how you would measure organizational
climate in this case Specify (a) the level (ie individual group organization) at
which the construct exists (b) the level at which you would measure the construct
and (c) the procedures that you would use to establish that measurement is aligned
with theory (ie the construct validity of the measure)
E) General (Measurement)
E1 Studies in organizational behavior research often rely on single-item measures of
key constructs The use of single-item measures has long been criticized based
on the premise that single-item measures are unreliable However Wanous
(Wanous amp Hudy 2001 Wanous amp Reichers 1996 Wanous Reichers amp Hudy
1997) has recently argued that single-item measures can exhibit adequate
reliability Wanous based this conclusion on a procedure for estimating the
reliability of single-item measures using the classic formula for correction for
attenuation Subsequent studies have yielded mixed results regarding the
conclusions of Wanous (eg Loo amp Kells 1998 Nagy 2002) and the veracity
of the perspective advocated by Wanous remains in question Summarize and
assess the arguments for and against the use of single-item measures and
evaluate the procedure and evidence offered by Wanous regarding the reliability
of single-item measures Based on your assessment and evaluation develop
recommendations regarding the use of single-item measures in organizational
behavior research

E2 Ipsative measures have become prevalent in organizational behavior research
Ipsative measures ask respondents to answer questions relative to one another
such that the scores for all questions sum to the same constant for all respondents
Examples of ipsative measures include rankings Q-sorts and the allocation of a
fixed number of points (eg 100) across a set of response options Ipsative
measures may be contrasted with absolute measures which ask respondents to
answer questions independently from one another Absolute measures are
exemplified by rating scales using an interval or ratio numeric response format
The relative merits of ipsative and absolute measures have been debated for
decades (eg Cornwell amp Dunlap 1994 Hicks 1970 Johnson Wood amp
Blinkhorn 1988 Saville amp Wilson 1991 1992) yet the fundamental issues
underlying this debate have not been adequately addressed in organizational
behavior research For example measures of organizational culture and values
are often ipsative and some researchers advocate these measures over absolute
measures (eg Meglino amp Ravlin 1987 OReilly Chatman amp Caldwell 1991
Ravlin amp Meglino 1987 see also Rokeach amp Ball-Rokeach 1989) Review the
relative merits of absolute and ipsative measures Based on your review which
form of measurement is most appropriate and why Do your conclusions depend
on the construct being measured If so what types of constructs are best suited to
ipsative measures and what types are best suited to absolute measures Next
apply your conclusions to the measurement of culture and values in
organizations What specific arguments have been advanced in favor of ipsative
measures of culture and values How sound are these arguments Should ipsative
measures be used in the study of organizational culture and values If not how
can absolute measures of culture and values be developed that address the
concerns voiced by advocates of ipsative measures Provide a specific example
of the type of measure you would propose

facets of a concept Although such measures are prevalent and in some cases are
advocated (eg Law et al 1998 1999) they can present a variety of conceptual
and methodological problems Describe the specific problems associated with
measures that use items representing different facets of a concept Compare these
problems with the purported advantages of such measures Conclude by

E5 Suppose Roberta Von Eisenbrick is a researcher interested in the consequences of
AFFECTIVE CONFLICT (AC) in decision-making teams She gets access to a
variety of outcomes assessment committees at each of 87 different schools in
the Dallas Independent School District and gains permission to tape-record two
of their meetings (one in February and one in March) Such committees have
been formed to develop quantitative ways to track pursuit of school goals and
provide accountability to local and state governments These are often divisive
teams with heated meetings because what gets assessed is what usually gets
rewarded After both of these meetings the committee members each
fill out a short questionnaire that contains 20 Likert-type items measuring how
much AC occurred (eg People in our group often get angry with each other)
The individual scores are summed across items then averaged across team
members to come up with a group-level AC score for each of the 87 2
meetings The same procedures are followed for a 5-item measure of Group
Cohesiveness (GC) which is predicted to be reduced by higher levels of AC
Roberta also listens to every tape and from her expert judgment she rates each
groups meetings on the same 20 items Those 20 ratings are summed for each of
the 87 2 meetings Now Roberta is interested in evaluating her measure She
wants it to have excellent psychometric properties including reliability and
construct validity

least three kinds of estimates and the sources of error each one assumes or is
estimating Pick one of those kinds of estimates and provide a rationale for using
it
c What is construct validity Discuss how the (un)reliability of the AC measure
could affect the conclusions one would draw from a study involving it and GC In
your discussion be sure to go over the connection between reliability and
validity and the connection between reliability and the probability of Type I or
Type II statistical errors

D) ModeratorsMediators
D1 Moderation and mediation provide different ways to model third variable effects
(a) Please define both of these terms (b) Sketch a conceptual model to show how
each relates to main effects (c) Using variables of your choice please write
hypotheses to reflect both (d) Explain how each is tested analytically
D2 Discuss moderators and mediators Provide an example of how (1) a moderating
variable influences the relationship between the independent and dependent
variable and how (2) a mediating variable influences the relationship between
the independent and dependent variable Describe how you would test for both
moderation and mediation using regression
D3 Many theories in organizational research predict that the effects of one variable
on another are moderated by a third variable Such moderator effects are
typically tested by entering the product of two variables as a predictor after
controlling for the two variables that constitute the product Several researchers
have pointed out that this product is often highly correlated with the squares of
the two constituent variables and have suggested that moderating effects may be
tested after controlling not only for the two constituent variables but also their
squares (eg Cortina 1993 Ganzach 1998 Lubinski amp Humphreys 1990
MacCallum amp Mar 1995) Discuss the strengths and weaknesses of this
approach as compared to methods that use only the product term and its
constituent variables Conclude with recommendations as to when and under
what conditions organizational researchers should test moderator effects with the
squares of the constituent variables in the equation

D4 Assume you are interested in studying relationships amongst three variables X
Y and Z Your first hypothesis posits Z as a mediator of the relationship between
X and Y Your second hypothesis posits Z as a moderator of the relationship
between X and Y Draw the figures depicting each of these hypothesized
relationships and describe (make sure to write regression equations) how you
would test each of these hypotheses
D5 The amount of time and effort that the average person pours into his or her job
has risen steadily over the last two decades such that the average person now is
working one more week per year than the average person in the mid 1970s This
steady increase has fueled research interest in the construct of Job Burnout (JB)
which is an emotional and physical exhaustion associated with ones work
Organizational Stress (OS) the perception of greater demands than available
resources in ones work environment is thought to be one of the chief
antecedents of JB However time spent under OS is thought to make its affects
on JB accumulate or worsen Work Role Withdrawal (WRW) the avoidance of
responsibilities or the deliberate reduction of inputs to ones job is believed to be
the chief consequence of JB

subdomains of management Further demonstrate your understanding of
moderator variables by picking which variable in (a) is the moderator Show the
moderating relationship in an X-Y (or multi-layered) chart Again what elements
or steps in a study design (not statistics) would be helpful for detecting the
moderating effect implied above

16) Q Your departmental chair is considering a new textbook and has asked for your
recommendations You conduct a well-designed controlled study (details are unimportant) and discover students who use the new book perform 10 better on a standardized subject
matter exam than those using the old book (p = 027) Both books are readily availabe their prices are almost identical and both are equally acceptable to the instructors What is your recommendation to the chair
F1 Attached is the beginning of an article Your task is to write the results section by
1 making up and reporting plausible descriptive statistics that will help the
reader understand the results of the statistical tests you report and the nature of your
sample (Hint this can be presented in the form of a table)
2 describing and defending your choice of appropriate statistical tests of the
hypotheses and the steps that you would go through in carrying out these tests
3 making up and reporting results of these tests that are consistent with your
descriptive statistics and with any information in the rest of the article about the
results found (Hint this can be presented in the form of a table)
4 describing how well these results provide support for the hypotheses You
may want to note any relevant threats to validity here
Be sure to state any assumptions you make
F2 Assume that the Personnel Manager of a local firm Ms B dFlandres hired you to
analyze some data that her assistants had collected over the past several years The
data consist of (a) job performance ratings that were made in June of 1990 and (b)
scores on 25 predictor variables (eg measures of education job experience job
tenure job aptitude personality) that were measured when the individuals were hired
(between April 1987 and May 1988) She had data from only the 110 subjects (60
males and 50 females) who were hired during the period and were still employed by
the firm One objective of your analysis (analyses) is to determine how well the
performance criterion can be predicted by the predictors What strategy would you
use in analyzing the data Describeexplain (b) Is sample size an issue for your
analyses Explain If it is what will you do to deal with problems stemming from
sample size Assume that no additional data can be collected at this time (c) Some
preliminary analyses that you do reveal that five of the predictor variables correlate
(zero-order basis) about 75 with one another Will this influence the analyses that
you use Will it influence the validity of conclusions derived from your proposed
analyses (d) Ms dFlandres is interested in knowing if the predictor variables are
equally effective in predicting the job success of males and females What analysis
or analyses would you do to deal with this issue
F3 Assume that you have been provided with data on 12 conceptually distinct variables
that are moderately correlated with one another at the empirical level The data are
from students in four different college majors ie astronomy (A) biology (B)
criminology (C) and demography (D) The 12 measured variables fall into the
general categories of mental health (tension emotional withdrawal hallucinations
guilt feelings blunted affect and suspiciousness) and job satisfaction (work itself
supervision co-workers pay promotion prospects and working conditions) Your
task is to determine if the individuals in the four college majors differ from one
another on the 12 measured variables
(a) What statistical technique(s) would you use to test for group differences
Explain Be specific about the procedures(s) that you would use
(b) What statistical estimate would you use to estimate the extent to which the
groups differ from one another Be specific
F4 The following statistical table published in a recent issue of Work amp Occupations
was taken from an article discussing variables influencing resistance and citizenship
behaviors in the workplace Resistance behaviors include playing dumb withholding
effort work avoidance subverting particular managers and sabotage Citizenship
behaviors include cooperation engaging in peer training use of insider knowledge to
facilitate production commitment to organizational goals giving extra effort freely
Both measures are global constructs aggregated to the interval level and
standardized
The table reports the results of a series of ordinary least squares regression equations
with standardized coefficients Explain the meaning of the statistics presented What
do these statistics tell us generally about the relationship between resistance
behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows
Anomie Index -standardized interval level measure tapping multiple dimensions
The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)
F5 Researchers collected data from a sample of 350 companies on the following
variables
size (measured as number of employees)
Business Strategy (a nominal variable with 2 response options low-cost provider or
differentiator)
HR Strategy (a nominal variable with 2 response categories High commitment or
low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

mirrors Explain both sides of the debate and then lay out the role of meta-analysis
as you see it within the time span of your career as an academic To do this use
examples of already written (or yet to be written) articles as models
J5 A frequent criticism of non-quantitative research summaries (literature reviews) is

affected the statistical outcomes of the studies included in the literature review Meta-
analysis however allows one to statistically examine such effects Assume you are
conducting a meta-analysis of the relationship between leader behaviors and group
productivity Briefly describe the steps you would take in conducting a meta-

assumptions usage and limitations
O3 How do exploratory and confirmatory factor analysis differ What are the
advantages and disadvantages of each
O4 Describe the differences between exploratory factor analysis (EFA) and
confirmatory factor analysis (CFA) When would you use one verses another
Are there ways to use EFA in a confirmatory way Can you use CFA in an
exploratory way Also describe the difference in principal components analysis
(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression

information in each matrix and its purpose
(2) For what purpose do researchers use factor analysis Explain In the process
provide a very brief description of a study for which factor analysis would be a

c the type of quantitative output that results from applying the technique
d how a researcher would use the output in his or her research

f the important issues and problems in using the technique
P) Structural Equation Models
P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)
Please comment on these restrictions versus access argument Which side do you
take
What are the strengths of SEM Give some examples
What are the weaknesses of SEM Give some examples

AMJ and ASQ
Why is theory considered so important
Give an example of a good theory and explain the elements that make it a strong
theory (Focus on theory development not on the content of the specific theory)
C6 You have undoubtedly heard the criticism of certain published articles in our
field being atheoretical Spoken as a criticism it suggests that research articles
should have theory Should every empirical article have theory Why is theory
important What are the hallmarks of good theory
2 RESEARCH DESIGN
A) Research Design Terms
5) Define internal and external validity Which is more important and why (It is not okay to
say they are equally important)
A1 Define (and discuss important features or issues concerning) the following
constructs of research design (Define any five terms)
1 Internal validity 6 Quasi-experimental
design
2 Stratified Sampling 7 Random Assignment
3 Solomon Four-group
design 8 Differential mortality
4 Factorial design 9 Demand
characteristic
5 External validity 10 Regression to the
mean
B) Level of Analysis
B1 IO psychologists have traditionally categorized themselves as being more micro or
macro in orientation usually falling toward the micro end Recent concern for what
has been termed the levels of analysis or cross-level approach has added a third
category - meso What is the meso level Is this just academic hairsplitting or re-
naming or is there a fundamental difference in this research strategy in contrast to
micro or macro Provide an example from some research domain of interest to you
that illustrates your conclusion of no real difference or important difference
C) Cross-Sectional vs Longitudinal Design
13) What are the benefits of a longitudinal design over a cross-sectional design in a non
experimental (correlational) study What are the disadvantages Why donrsquot we see
more longitudinal research
C1 The use of cross-sectional research designs continues despite many calls for
replacing them with longitudinal designs (a) What are the main strengths of
cross-sectional designs (b) What weaknesses do they have that longitudinal
designs supposedly counter (c) What are the implications of cross-sectional
designs for theory development (Consider internal and external validity)
C2 A good number of research efforts on the micro (OBHR) side rely on cross-
sectional designs in which surveys are used to collect both IVs and DVs from the
same respondent What are the various problems associated with such a design
What changes could be made to this design to alleviate andor eliminate these
problems What are the downsides of the new design (add in conveniencenon
probability samples)
C3 What are some of the major strengths of a longitudinal design Why dont we see
more of them
C4 Assume that you are analyzing a large sample of longitudinal survey data TH
Identify two characteristics of your data that would make ordinary least squares
regression (OLS) inappropriate for conducting analyses For each of these
characteristics describe an alternative analysis that is superior to OLS
D) Qualitative vs Quantitative Designs
D1 Compare and contrast the objectives strengths and weaknesses of
qualitativeobservational methods (eg ethnography) versus quantitative methods
(eg survey) in conducting empirical research on macro organizational issues Be
sure to consider issues of reliability generalizability validity ethics and
practicality in your answer Describe situations where one method or the other
may be most appropriate
IC
D2 In recent years a number of individuals have taken the position that qualitative
research is superior to quantitative research a Compared with quantitative
research what are the principal strengths of qualitative research b Compared
with quantitative research what are the principal weaknesses of qualitative
research
E) Observation vs Experiment
E1 Compare and contrast the objectives strengths and weaknesses of observational
methods (eg ethnographic methodology) and experimental methods Be sure to
consider issues of precision generalizability and realism in your answer Consider
also situations where one methodology or the other might be most appropriate
F) Laboratory vs Field Research
F1 Of the various research approaches available to organizational researchers
laboratory experiments are held up as an ideal because of their potential for high
internal validity On the other hand field research including participant observation
and field experiments have high potential for external validity Discuss specifically
the strengths and weaknesses of laboratory versus field experiments How would
positivist researchers think differently about these tradeoffs than would
phenomenologists
F2 In conducting an experiment in the laboratory or designing survey research there are
certain unique opportunities and limitations of each research strategy A) Describe a
hypothesized relationship between two constructs an independent and a dependent
variable in a substantive area of your choice (eg Strategy OB HRM
Organizational Theory) provide a verbal mathematical and graphical statement of
that hypothesis B) Briefly discuss how you would examine this hypothesized
relationship in a laboratory using experimental techniques versus a field survey using
correlation techniques C) Discuss what may be considered typical strengths and
weaknesses of each strategy regarding issues of precision and control in the
manipulation or measurement of the variables of interest realism of the context for
the participants and generalizability of the findings to other elements of a chosen
population D) Finally discuss advantages if any of using laboratory and field
survey methods in tandem
G) Experimental Design
2) A colleague suggests to you that only true experiments can provide useful results in
science Why might she say this What would you offer as a defense for the role of quasi-
experimental and non experimental designs in the context of the social science In
answering this question make sure you identify the defining characteristics of each design
type
9) Why and when should we be concerned about non response in research What are the
things we can do to try and decrease non response (or increase response rates)
11) Why might a researcher choose to utilize an experimental design that incorporates pretest
measure on the DV
G1 Experimental designs oftentimes come under attack due to perceived limitations in
external validity (a) Relative to other design types what strengths and weaknesses
do they offer (b) What experimental design structure is the strongest Why (c)
What is the relevance of research design for results and theory development
G2 Meta-analysts often investigate whether the quality of research design (eg
randomized experiments vs non-randomized designs) influences average effect
size In their meta-meta analysis of psychological educational and behavioral
treatments Lipsey and Wilson (1993) found that In a given treatment area poor
design or low methodological quality may result in a treatment estimate quite
discrepant from what a better quality design would yield but it is almost as likely
to be an underestimate as an overestimate (p1193) A few methodologists (eg
Shadish) have attempted to identify factors that may explain the relative magnitude
of effect sizes from randomized and nonrandomized experiments Please review
these findings and add your tentative model of the conditions under which random
experiments will produce larger smaller or equal effect sizes relative to
nonrandom designs Discuss possible implications for research design in the
context of real-world interventions
G3 Analysis of covariance and randomized blocks designs are sometimes referred to as
noise-blocking designs Explain what this means and give an example of (a) a
randomized blocks experiment and (b) an analysis of covariance experiment Keep
your examples simple Describe how such designs are noise-blocking when used
with randomized assignment of subjects to experimental condition and contrast
that with the role such designs serve in quasi-experimental designs
G4 Team performance in Bafko Industries varies considerably across teams and from
month to month The senior VP in charge of team development thought that a team
training program could improve the performance of these teams A consultant
convinced him that his firms training program which lasted only one week and
cost only $25000 per team) could raise the performance of Bafkos teams The VP
however wanted to experimentally test the efficacy of this training program before
he adopted it widely throughout the firm So the consultant suggested the following
experimental test
There were 48 teams in Bafko that showed significant variation from month to
month in their level of performance The consultant chose the 24 worst performing
teams based on last months data and assigned them to the training group After
all he argued these were the ones who most needed it The other teams were
assigned to the control group The training group received the training program
(lasting one week) at the beginning of the next month while the control group
teams did their normal routine Performance scores were gathered at the end of the
month The results showed that the training group teams had a significantly larger
rise (ie statistically significant) in their performance than did the control group
teams (who as a group did not improve at all) The consultant proudly displayed
these results and argued that they convincingly demonstrated the efficacy of his
program
How would you advise the VP Specifically what is the validity of the consultants
conclusions If you think he might be mistaken what specific threats to internal
validity are particularly plausible
G5 Consider the following design
N O Xa O
N O Xb O
N O Xc O
N O O where
Xa Xb and Xc represent different levels of a training program that varied in its
length across three different work groups In group a the training time was 40
hours in group b it was 30 hours and in state c it was 20 hours The training was
designed to instill customer service values in the team members O represents a
measure of customer service attitudes measured with a 20-item Likert scale This
measure was administered one week before the training program and 3 months
later The researcher hypothesized that the training program would improve
customer service attitudes and that longer training would have stronger effects
The design is a non-equivalent groups design because people were not randomly
assigned to groups even though groups were randomly assigned to treatment
condition Each group has a sample size of 36 members The reliability of the
customer service attitude scale was 78 at the pretest and 80 at the posttest The
pretest means were as follows
Group A 26
Group B 23
Group C 27
Control Group 25
a Construct a regression model that will test the researchers hypothesis Be
explicit here describing each variable in the model and what regression effect(s)
you would expect to find if the hypothesis were correct (Hint everything you need
to know is in Trochims chapter 11 and what we discussed in class) (10 points)
b Describe any serious threats to internal validity (10 points)
c Discuss how you might amend this design to improve its internal validity(10
points)
G6 Often in organizational research the researcher is faced with having only one group
on which to experiment and thus cannot use a control group when conducting
experiments This occurs for example in taxation experiments when you cannot
selectively apply new tax laws to different groups or when you wish to test the
efficacy of an incentive plan that must be applied to all members of a company In
such situations the researcher must be creative in assembling a quasi-experimental
design that has high validity (and usually the challenge concerns internal validity)
Consider the following scenario
A manager of a retail store wants to test the efficacy of an incentive program in
changing the selling behaviors of her retail sales clerks Specifically she wants to
test a behavioral reinforcement program in which sales peoples behavior is
recorded on in-store video cameras The tapes are analyzed each night and the
experimenter tabulates the frequency of various behaviors (eg offering assistance
to customers restocking items straightening up displays suggesting accessory
items to accompany the items that a customer is purchasing) The manager then
rewards the clerks with a monetary bonus based on the frequency of desired
behaviors She would like to conduct a valid experiment to see what effect such an
incentive program has on employee behavior but because of concerns about
employee morale she cannot assign clerks to treatment and control groups Instead
she has to apply the experimental treatment to everyone in the store She learned in
her research methods class (which the company requires all its managers to take)
that a single group experimental design typically has very low internal validity
Your job as a consultant is to help her design an experiment given her constraints
that would produce interpretable (ie internally valid) results Describe the details
of the design you would recommend using the notation in Trochim (2001) If the
design you come up with has a specific name use it As part of describing your
design discuss how the data would be analyzed and what particular effect you
would look for
G7 Why are experimental research designs held in such high regard
G8 Compare and contrast experimental quasi-experimental and correlational research
designs What characteristics separate these three designs What are their
advantages and disadvantages especially in comparison to one another
G9 What is the difference between a within-subjects experimental design and a
between-subjects experimental design When might a within-subjects design be
appropriate When might it be inappropriate
G10 Describe the difference between a basic within subjects and between subjects
experimental design What are the advantages and disadvantages of each
especially in comparison to one another Give an example from your area of
research in which each would be appropriate
G11 What are the major threats to the internal validity of a pretest - post test
nonequivalent control group design How can this design be improved with regard
to increasing a researchers ability to make causal inferences
G12 A production manager is interested in testing the hypotheses that participation in
quality circle programs will result in increased productivity and reduced
absenteeism A questionnaire is administered to a group of 92 employees
concerning their attitudes toward such programs and 46 with the most favorable
attitudes who are willing to participate are selected for the treatment group The
remaining 46 are the control group Measures of performance (unitsmonth for the
group) and absenteeism (lost daysmonth for the group) are kept over a three month
period during which the treatment group has weekly quality circle meetings The
results are as follows
Month 1 Month 2 Month 3 Month 1 Month 2 Month 3
Performance Absenteeism
Treatment 100 115 121 6 9 4
Control 110 108 113 6 8 5
The manager calculates t tests between month 1 and 3 The only significant
difference is performance for the treatment group so the manager concludes that
quality circles raise productivity but do not have an effect on absenteeism What
are the primary threats to internal and external validity in this study What are
possible alternative explanations for the differences (or lack of differences)
between the two groups What additional information might help explain these
results
G13 One stream of current strategy research contains event studies In these studies
investigators basically correlate the reaction of a financial market to the presence
andor absence of the occurrence of some event at a firm (eg the resignation of a
CEO) In a different approach to such a study suppose that one investigator (Jean)
conducts a natural field experiment on the effects of competitor mergers on a
firms environmental scanning activity Through previous arrangement Jean has
been working with 5 medium-sized computer hardware and 5 medium- sized
software firms on the west coast Shes been collecting a paper trail of internal
memos reports and phone calls that might measure environmental scanning
activity Shes been finding that the firms in both industries do about the same
amount of scanning (no significant differences) However in the midst of her data
collection Norton announces a merger with Symantec (software) A year later
Jean compares the amount of post-merger environmental scanning in the software
industry with that in hardware industry Just as Jean had hypothesized a t-test
shows a greater amount of post-merger scanning among the software firms She
concludes that her hypothesis was supported mergers of competitors cause an
increase in scanning
Critique the study described above in terms of its design flaws Identify the design
Jean used Briefly allude to problems the study has with external validity but
concentrate on the Cook and Campbell threats to internal validity Provide a
rationale for why each threat is or isnt operating in the study Link each of the
relevant threats to the specific constructs being studied (mergers and environmental
scanning) Finally do a summary evaluation -- what can be learned from this
study
H) Quasi-Experimental Design
H1 The University of Mississippi observed that the graduation rate of students with poor
grades during their freshman year was much lower than those with better grades
Wanting to improve the chances of these low performing students they tested the
effects of a new rule for freshmen The rule stated the following At the end of their
first semester all students with a GPA between 200 and 225 must register for
EDUC 1003 during their second semester Students with a GPA lower than 200
were put on academic probation EDUC 1003 consisted of a course whose objective
was to help students develop good study skills The theory was that poor study skills
were a significant cause of poor academic performance and that study skills could
be learned
They wanted to evaluate the effectiveness of this intervention so they collected data
on the GPAs of students beginning with their first semester and continuing through
to their third semester At that point they wanted to analyze the data to determine
whether the new rule was making a significant difference in the students academic
performance
What is the best way to analyze these data to reach an interpretable conclusion
Describe your approach and then discuss the major threats to validity that it has
Their sample size of students was as follows
Total N= 3454 (these are students who completed all 3 semesters)
Number of students with first semester grades between 200 and 225 (and thus took
EDUC 1003) was 956
H2 A nationwide furniture company wants to determine if a diversity training
program will improve individual sales performance on the floors of its urban retail
outlets A group of 45 salespeople in one city were given two weeks of training
Measures of individual sales performance were taken once two months prior to the
program and once two months after Forty-five salespeople (who did not receive the
training) in a similar city had the same measures taken at approximately the same
points in time The training group increased their average weekly sales from $14000
to $16500 while the non-training group improved theirs from $13000 to $14500
The change for the training group is statistically significant the change for the non-
training group is not
How would the interpretation of these results in this quasi-experimental design
differ from a true experimental design What are the threats to internal validity in
the above study and how might they be operating (be specific) What additional
information and analyses would be useful in controlling for these threats
H3 An accounting firm is interested in determining if a re-training program will reduce
errors made by its audit teams A group of 45 auditors in the home office location
are given two weeks of re-training Measures of the frequency of detectable errors
are taken once two months prior to the program and once two months after Forty-
five auditors in similar office at a branch location have similar measures taken at
approximately the same points in time The training group reduced their average
number of errors per audit from 8 to 3 while the non-training group reduced theirs
from 11 to 9 The change for the training group is statistically significant the change
for the non-training group is not
How would the interpretation of these results in this quasi-experimental design
differ from a true experimental design What are the threats to internal validity in
the above study and how might they be operating (be specific) What additional
information and analyses would be useful in controlling for these threats
H4 Describe the main classes of threats to validity that are found in quasi-experimental
research designs
H5 Dr Delta an organizational development consultant was hired by a firm that has
600 pizza parlors nationwide to assist in implementing organizational changes that
he hopes will result in higher levels of job involvement At the outset of the study
subjects had jobs with very low levels of enrichment and were paid on an hourly
basis He designed an experiment in which stores were randomly assigned to one of
three treatment conditions Condition 1 subjects experienced job enrichment (JE)
and a change to performance-based pay (PBP) Condition 2 subjects experienced
only JE and Condition 3 subjects experienced only PBP The parlors were
sufficiently far apart from one another and communication among the parlors so
poor that subjects in any parlor were totally unaware of changes made in other
parlors At the end of 18 months he measured the job involvement levels of workers
and then tested for differences between the three conditions using a standard one-
way analysis of variance In view of Dr Deltas design answer the following
questions
How sound is Dr Deltas design Comment on the weaknesses of the design
I) Interrupted Time Series Design
I1 What threats to internal validity are and are not ruled out by an interrupted time series
design that includes the introduction of a treatment and its removal at a subsequent
time period List and explain In the process be certain that you provide a diagram
that illustrates such a design
J) Validity Some Questions are about the validity of a measure others about experimental validity)
10) Identify four threats to internal validity and briefly describe what they mean
J1 It was some time ago that the tripartite view of validity was abandoned in favor of a
unitarian view in which different evidentiary bases for validity might be put forward
Binning amp Barrett (1989) represent an attempt to place multiple evidentiary bases into a
single framework Cook amp Campbell (1979) describe four aspects of validity but they
arent really meant to represent evidentiary bases Adding to the confusion is the fact
that while Binning amp Barrett and Cook amp Campbell use some of the same terms these
two pairs of authors clearly mean different things by these terms and intend for them to
be used in different ways Your task is to 1) Describe the evidentiary bases discussed
by Binning amp Barrett 2) Describe the aspects of validity described by Cook amp
Campbell 3) Describe the similarities and differences between the two lists including
the different purposes served by the two lists and 4) Present a single framework that
incorporates both This last task is the most important of the four
J2 What are the types of validity How would each affect an empirical study IC
J3 Define both internal and external validity Which is more important (it is not okay to
say that they are equally important) Defend your reasoning
J4 Why might someone argue that the construct validity of a measure can never really be
established
J5 Describe each of the following forms of validity content convergent discriminant
criterion-related and construct How is each assessed How do they related to each
other Which is most important (Make sure you defend your answer)
J6 Define and explain 6 of the 8 types of validity listed below and describe the type(s) of
information each provides Choose one specific type of study as an example (eg
cross-sectional study experiment quasi-experiment simulation ethnography etc) and
compare and contrast the usefulness and importance of each type of validity for that
type of study
-- Concurrent validity
-- Construct validity
-- Content validity
-- Convergent validity
-- Discriminant validity
-- Statistical conclusion validity
-- Internal validity
-- External validity
J7 Designing empirical research has been called making a series of trade-offs
Unfortunately decisions that are made to increase one desired quality (like internal
validity) can also decrease another desired quality (like external validity) For each of
the issues below discuss the concerns involved (ie the trade-off) and identify the
qualities that are being increased or decreased
a laboratory vs field study
b using a 5-item measure vs a 1-item measure
c using a student sample vs a sample of full-time employees
d using a sample of employees from one company of 5000 vs 500 employees from
each of 10 companies
e collecting your data using one method vs collecting your data using multiple
methods
J8 There are four major types of validity in social science internal validity external
validity construct validity and statistical conclusion validity Please address the
following three issues concerning validity
a What is the meaning of the four major forms of validity (ie internal and external
validity construct validity statistical conclusion validity)
b Are there trade-offs that can or must be made among the four types of validity
d Describe how the concept of validity varies across the research traditions of
experimental vs observational research
IC
J9 The quality of research is often assessed by examining validity issues As you are
aware there are numerous typesforms of validity (eg internal and external validity
construct validity statistical conclusion validity) These types of validity address
different aspects of the research process For this question please address the following
issues
a What is the meaning of the four major forms of validity (ie internal and external
validity construct validity statistical conclusion validity)
b Should there be a priority among these forms of validity If yes why If no why not
c Does the concept of validity vary across research traditions (ie experimental vs
observational research) If yes why If no why not
J10 External validity has received considerable attention in the social and behavioral
sciences Some researchers argue we are too concerned with the external validity of our
findings while other researchers argue that we are too unconcerned with external
validity Several points of view have been developed to explain what is external
validity When answering this question please be sure to address at least the following
issues
a Compare and contrast alternative conceptualizations of external validity
b Some researchers have argued that the role of external validity is invariant across
research traditions (ie experimental vs observational research) Defend the
perspective that the role external validity is invariant across these two research
traditions In addition present the weaknesses of this perspective
J11 In designing a research study researchers must consider trade-offs between internal and
external validity Explain what is meant by internal validity and external validity What
is the nature of these trade-offs How would you evaluatedetermine which is more
important internal or external validity for a particular study Why is this such an
important issue in organizational studies
J12 A researcher conducted a quasi-experiment to test the effects of participative decision
making (PDM) on job attitudes of employees Employees from different departments in
a large organization were assigned to either a treatment group (PDM implemented) or a
control group (no PDM) Random assignment was not possible because of work
schedules coordination of tasks etc Thus the design can be considered an untreated
control group design with pretest and posttest and is represented as follows (where
O=observation X = treatment)
________________
O1 X O2

The results of the experiment are presented in the graph below [no graph provided]
The dependent variable is job satisfaction and is measured on a 100 point scale (with
100 being extremely satisfied) How amenable are these results to causal interpretation
What is (are) the major threat(s) to internal validity B if any B for this type of design
given these results What steps can be taken to assess the extent of this (these)
threat(s)
K) Data Collection Methods
14) Describe the various methods of data collection (eg survey interview observation etc)
available to a social scientist What are the advantages and disadvantages of each relative to
each other
K1 Within micro organizational research much criticism has been raised concerning
the reliance on self-report survey data What potential problems does self-report
survey research raise How big of a problem do you think this is
K2 There are a number of methods for collecting data (eg survey interview archival
etc) that are available to a social scientistorganizational researcher Discuss each in
terms of their strengths and weaknesses both on their own and in comparison to one
another
K3 Pick an important construct in your favorite area of management research for which
there is some controversy about how it should be measured or operationalized (eg
environmental munificence or growth need strength) Give the prevailing verbal
definition of the construct and analyze the measurement controversy from two
broad angles First discuss how the controversy may or may not stem from claims
about how one measure is better or worse than another because it (or the other) is an
(a) archival record (b) direct observation (c) social report or (d) self-report That is
what are the relative strengths and weaknesses of each of these types of
measurement for the construct youre discussing Second discuss the construct
validity of the most commonly used measure(s) of this construct To answer this
second part you need to discuss just what construct validity is and how it can or
cannot be demonstrated In the situation you describe what could be done to
demonstrate or improve the construct validity of existing measures
K4 Interviewing in some form has been the workhorse for data collection in a variety
of research traditions positivistquantitative ethnographic feministpost-modernist
and increasingly historical research While each tradition elicits information from
respondents the goals and processes involved in interviewing vary considerably
across research traditions Discuss the purposes of the interview the relationship
between data and theory the roles assumed by the interviewer and the respondent
and the relevant criteria for assessing the validity and reliability of the information
obtained In addition compare and contrast the use of the interview as a data
collection method in the positivistquantitative tradition with its use in one of the
alternative traditions
L) Common Method Variance
L1 Many of us have had concerns about the reviews of our survey research which
suggest that data analyses of surveys are biased because of common method
variance effects of individual differences such as negative mood negative
affectivity and social desirability and the reliability and validity of the constructs
we are attempting to measure Define how these problems affect a research issue in
organizational behavior and the steps that might be taken to minimize such potential
criticisms of papers based on analyses of self-reported data through survey
instruments
L2 In a series of papers by Spector (1994) Schmitt (1994) and Howard (1994)
published in the Journal of Organizational Behavior arguments were provided for
and against the use of self-report questionnaire measures One of the issues
discussed that could limit conclusions drawn from relationships observed using self-
report measures was method variance What is meant by method variance what are
its sources and what impact is it expected to have on research findings
M) Sampling
M1 The manufacturing census samples all plants of 250 employees or more For
plants of 5-249 employees it takes a size proportional sample Plants of 1-4
employees are not sampled What challenges does this sampling method provide
to researchers What could you do to account for these problems if you were
TH
studying organizational (not plant) growth
M2 New York State has approximately 250000 employees in over 70 state agencies
commissions and boards ranging in size from approximately 50 to over 5000
employees Assume that you wanted to draw a representative sample of 1000
employees Describe two ways that you could draw such a sample and briefly
describe the advantages and disadvantages of each of these sampling approaches
IC
M3 The director of a national non-profit agency with approximately 10000
employees located primarily in regional offices in each of the 50 states the
United States has approached you and asked you to develop a study
(organizational survey) of organizational culture within the agency The agency
is about to embark on a variety of change initiatives including developing team
structures and the study is meant to examine various elements of organizational
culture that are potential barriers to change The director has indicated that he
would like to have the data analyzed at both the individual and office level of
analysis Because of funding limitations the agency will only be able to send the
survey to 1000 employees The director has indicated that there are three ways
of sorting employees all employees listed alphabetically all employees listed
alphabetically by state and all employees listed alphabetically by region (there
are between five and ten regions per state) Given these three ways of sorting
employees describe at least three different sampling approaches and the
advantages and disadvantages of each
M4 In your role as Teacher of Organizational Studies you are asked to prepare a
tutorial for beginning doctoral students on sampling design Assume that this
tutorial is part of a basic class in research design and that students in this class
have had a basic statistics course up to and including multiple regression Your
tutorial should focus on briefly defining and explaining the differences between
probability and non-probability samples You should make sure to present and
describe several types of probability samples (eg random systematic
stratified etc) and non-probability samples (eg convenience snow-ball quota
etc) and discuss general principles for when to use a probability vs a non-
probability sampling design For each sampling design you should also provide
at least one clear example of a situation where this type of sampling design is
appropriate
N) Cross-Cultural Research
N1 Discuss the problems in conducting cross-culturalnational comparison in terms
of (1) conceptualization and (2) research design and data collection
Define the three levels of measurement invariance How would the problems that
you have identified in part (a) affect measurement invariance How would you
examine measurement invariance by confirmatory factor analysis
TH
N2 Explain why using national boundaries as independent variable in cross-cultural
studies may not be appropriate in terms of theory and research methods What
alternative ways would you recommend
IC
O) General
O1 In your readings research has been described as choices among conflicting goals
(desiderata) For instance when choosing among research strategies a researcher
must choose among the desiderata of precision realism and generalizability The
trade-offs among desiderata occur for all aspects of research that is for the selection
of theories the treatment of independent variables research strategies the selection
of the problem to study rules of evidence for determining the meaningfulness of a
research finding and even the frameworks that describe the research process
Discuss what you see as the major trade-offs for each of the following aspects of
research That is discuss what you see as the major strengths and weaknesses
(advantages and disadvantages) of each aspect
a The trade-offs between internal and external validity
b The manipulation of the independent variable vs the observation of the
independent variable
c Basic vs applied research
3 DESIGNING A RESEARCH STUDY
A) General (Research Design)
3) Why is control so important in research design What are the different ways it can be
achieved (give a brief description of each control method) What are advantages and
disadvantages of each
A1 It has become almost a truism to note that the choice of methods influences theory
and questions data and conclusions (the causal direction might also be reversed)
Briefly discuss how the methods used have influenced research in any two of the
following areas leadership power and politics organization culture organization
justice Compare and contrast as possible Suggest some potentially fruitful
methodological directions for future work in these same topical areas and dont be
shy about reflecting on broader issues of how the field of organizational behavior
constructs its realities Lastly tie your discussion and reflections back to your own
future as a researcher what lessons or guidance do you derive from your
understanding of these issues
A2 Characterize as fully as possible what you see to be the methodological approach or
approaches in strategic management research Is there a dominant method or a wide
variety Discuss the reasons for the situation What are the advantages benefits etc
of the approach(es) in use What assumptions (ontological epistemological
ideological) do they embody Are current efforts ideal or at least adequate Are
there other approaches that could be useful If so how might researchers be
encouraged to use these as well If you see no advantage to more variety in
methodological approach support that point of view
A3 Describe a research question or area of interest to you and why you think it is not
only of interest but significance Using your understanding of research methodology
describe two ways of pursing the question that are as divergent on as many
dimensions as you can imagine Describe the advantages and disadvantages of each
approach How strong a link or fit is there between a research question and a
method
A4 In his 1957 article entitled The two disciplines of scientific psychology Cronbach
discussed the assumptions goals and methods used in experimental methods and
correlational methods in psychology
a According to Cronbach what is the main difference between the two disciplines
b Discuss the strength and weaknesses of each discipline
c What if anything could be done to improve the situation
B) Designing a Research Study
B1 Cook and Campbell describe the experiment as the research design with the
greatest methodological rigor However given the constraints present in most
organizations I-O Psychologists cannot often conduct experiments in applied
settings and must settle for techniques with less control than experiments
Describe a study to investigate the relationship between participation in a
supervisor training program and work performance which could realistically be
conducted in an organization If an experiment is not possible describe how you
would go about maximizing your ability to draw valid conclusions from your
design
B2 The XYZ Co has recently developed a sexual harassment web-based training
program The developers claim the program will cut training time and costs and
will be as effective or more effective than classroom-based sessions They
believe that this will be due to the increased availability of the program and the
ability for participants to review program material on demand Before the XYZ
Co developers launch this product they want you to determine if their claims
have merit Explain how you would design a study for this purpose
B3 Research suggests that demographic diversity improves group creativity but
reduces group efficiency Some argue that demographic diversity is just a proxy
for value and experience diversity and that demographic diversity on its own is
meaningless Design a test to settle this argument
TH
B4 E-mail has become a common form of communication in organizations and is
used for both formal and informal communication Because it has become so
IC
popular some people complain that the frequent use of e-mail leads to
miscommunication because they receive communications in e-mail that should
be accomplished through face-to-face or telephone conversations where there is
an opportunity for interaction You are interested in looking at this
phenomenon You are most interested in describing how e-mail is used for both
formal and informal communication and in examining the effect of the e-mail
use on organizational communication effectiveness Design empirical research
to address those issues
Describe your study in detail thoroughly explaining the research design
sampling plan data collection procedures ethical issues and proposed data
analysis for your research design Be sure to discuss the internal and external
validity of your research Which validity threats are ruled out and which
remain
REMEMBER Be thorough Your research design should demonstrate that you
are a competent researcher who is knowledgeable about the proposed research
methodology or methodologies Therefore be sure that you carefully describe
and give technical explanations for each component of your research
B5 Choose a specific situation involving employee selection eg artists for an
advertising agency (a) What strategy would you use in selecting the selection
measures (b) How would you combine the measures eg which measures
would you combine in a compensatory manner and which is a noncompensatory
manner (c) How would you assume test fairness defining various measures of
the term (d) How would you make final selections (e) How would you
validate your procedure (f) What considerations would enter in if your
company were too small to provide validation data (g) What difference would
it make if you were developing a procedure for deciding whether trainees
should be promoted as opposed to making new hires Please note--emphasize
but do not limit yourself to statistical issues
B6 There is evidence in the marketing literature of a non-monotonic relationship
between the expectations that customers have for retail service and their
eventual level of satisfaction with that service That is as a customers
expectations for service increase so does their eventual service satisfaction --
up to a point After that point the greater the expectations the lower the
eventual satisfaction Develop a hypothesis that includes a moderator variable
that might account for this evidence Give some reasonable rationale for it State
your hypothesis verbally as an equation as a directed graph (circle amp arrow
diagram) and as an X-Y function chart Discuss how it would or would not be
possible or useful to test your hypothesis via a laboratory experiment In your
discussion cover how and why a researcher could (not) manipulate the
independent constructs involved (mode X) whether or not random assignment
to conditions (mode R) is possible (including how may conditions would be
necessary) which alternative constructs could or could not be controlled (mode
K) and which constructs should be measured (mode Y)
B7 Assume you are the chairperson of a committee that must evaluate
undergraduate programs at your university Your task as chairperson is to
devise an approach (a design a research strategy a set of measures) that will
allow you to evaluate undergraduate programs Make sure that your approach
can be used in the future and at other comparable universities When developing
your plan be sure to address at least the following issues
a the type of design you would select Compare and contrast the selected design
with another possible design
b the type of research strategy you would select Compare and contrast with
another possible strategies
c discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
B8 Assume you are an organizational research design expert assigned to the
Strategic Planning Department of a large multi-national manufacturing firm
The Department has developed a new PC-based software package called
STRATPACK The software (and a one-week training course to learn how to
use it) is intended to improve the long-range planning ability of middle and
upper-level managers
Your job as research design expert is to devise research (a design a research
strategy a set of measures) that will allow you to evaluate the effectiveness of
the STRATPACK program Describe a research design for evaluating the
program Make sure that your research approach can be used in the future and at
all sites in the company When developing your plan be sure to address at least
the following issues

least internal external and construct validity
B9 Assume you are a consultant hired to evaluate the effectiveness of an industrial
safety program undertaken by a large manufacturing organization The safety
program is a behavioral one that provides rewards such as monetary bonuses or
extra paid vacation days for safety behaviors in terms of accident-free days
weeks etc Your task is to devise an approach (a research strategy a design a
set of measures and a general analysis strategy) that will allow you to evaluate
the safety program Because of the potential for the influence of many
extraneous variables on any safety program it is difficult to design research a
single cross-sectional study than can evaluate the impact of a single safety
program How would you design a study to evaluate the impact of the safety
program When developing your plan be sure to address at least the following
issues
a the type of research strategy you would select Compare and contrast with
another possible strategies

B10 One of the most important areas of research is forecasting of human resources
needs based on strategic positions of organizations For example NY State must
carefully forecast its human resources needs as it proceeds with significant lay-
offs of state employees Future human resources needs are generally evaluated
by either statistical ie regression or simulation or clinical judgment i e
supervisors judgments methods
a Design a single study that addresses the empirical question of whether
statistical or judgmental methods are better for forecasting human resources
needs You may discuss a program of research but please be quite specific in
your description of the first study
b What are the critical methodological issues in doing this kind of research
c What are the critical applied (or practical) issues in doing this research
d Are the issues in b and c related
B11 In the past decade computinginformation technology has changed many
aspects of organizational life For example the technology can make increased
decentralization possible by improving communication between central offices
and field offices Computer networks and word processors can enhance group
empowerment by making it possible for team members to create and edit
written group products quickly even if the individuals are at different locations
Some have argued that computinginformation technology will foster the
paperless productive office nevertheless others argue that the technology only
increases paper and reduces office productivity You are applying to the
National Science Foundation for a grant to conduct research that examines the
impact of computing information technology on organizational decision
processes The NSF application procedure imposes five basic requirements that
your research design must fulfill in order to receive funding Note A very
significant factor affecting NSF grant decisions is a clear demonstration that the
researcher is knowledgeable about the research methodology used Write your
response to each of the following five grant requirements Be sure not only to
respond to the requirement but also to demonstrate your research
competence
1You must design a study that uses two different methods
(interviewobservation survey experiment or quasi-experiment) Describe your
two methods in detail and provide a rationale for the key elements (eg
sampling data collection proposed analysis) of your methods Be sure to
discuss and evaluate the internal and external validity of both methods
2 As part of your research design you must select a conceptual (latent) variable
central to your proposal (use centralization of decision making as your
variable) and describe how you will develop your own measure (You may not
simply use off the shelf instruments)
3 You must describe how you will test for the reliability of the measure
(centralization of decision making) you developed in step 2 The NSF insists
that you describe how you will evaluate both the temporal stability and the
internal consistency of your measure Be sure to discuss what temporal stability
and internal reliability mean and how they are related
4You must describe how you will assess the validity of the measure
(centralization of decision making) you developed in step 2
5 NSF requires a brief statement and defense of the philosophy of science
underlying your research Discuss your position and show how your research
design is consistent with your philosophy
B12 Many organizations in the United States economy have installed some form of
Empowered Teams as an alternative or supplement to traditional bureaucratic
structure Preliminary evidence of the effectiveness of empowered teams
however is mixed--some organizations have claimed success and others have
reported failures The evidence however is predominantly anecdotal--written
for trade magazines by the organizations themselves There are few rigorous
empirical studies assessing the effectiveness of empowered or self-managed
teams You are applying to the United States Department of Labor (USDOL) for
a grant to conduct research that examines the effectiveness of empowered
teams The application procedure of the USDOL imposes three requirements
that your research design must fulfill in order to receive funding Write your
response to each of the three grant requirements The importance of each section
is implied by the evaluation points allocated by the USDOL to each of the three
requirements given in parentheses
1 (50 points) Your study design for assessing Empowered Team effectiveness
must use two different methods (interview observation archival analysis
survey simulation experiment or quasi-experiment) Describe in detail and
thoroughly explain the sampling plan instrumentation data collection
procedures and proposed data analyses for both methods Be sure to discuss the
internal and external validity of both methods and how the two methods
complement one another
2 (30 points) As part of your research design you must select one conceptual
(latent) variable central to your proposal and describe how you will develop
your own operationalization of the measure (You may not simply use off the
shelf instruments) Use the concept of group morale to demonstrate your
operationalization methodology Be sure to explain very explicitly to the
USDOL how you will assess the validity and reliability of the group morale
measure you are developing
3 (20 points) The USDOL traditionally has funded research conducted only
within the general paradigm of logical positivism but now is more open to other
research paradigms as well Your grant proposal must provide a statement and
defense of the explicit philosophy of science underlying your research Describe
your philosophy of science and show how your research design is consistent
with your philosophy
REMEMBER Be thorough You not only must design effective research but
you also must demonstrate to the USDOL that you are a competent researcher
It is absolutely vital to the USDOL that the principal researcher is
knowledgeable about the proposed research methodologies Therefore be sure
that you always carefully describe and give technical explanations for each
component of your research design and explain all technical terms (eg
Cronbach alpha KR-20 Likert scale)
B13 Assume that you are working as part of a research team that is responding to a
RFP (Request for Proposals) from a funding agency for research on work
socialization and newcomer adjustment The RFP calls for rigorous field
research that tests the effectiveness of theory-based interventions aimed at
facilitating the adjustment of new organizational members to complex andor
stressful work conditions The major goal of your teams research is to test the
effectiveness of a self-regulation intervention which trains newcomers to
identify and use relevant social information and cues to regulate work behavior
Your group hypothesizes that self-regulation training will be more effective
than other common treatments or interventions (eg realistic job previews
institutionalized socialization tactics)
You have been included in the team because of your methodological expertise
Your role is to design a rigorous field experiment or quasi-experiment to test he
effectiveness of the self-regulation training program REMEMBER THE
MAJOR CRITERION FOR FUNDING IS THE RIGOR OF THE RESEARCH
DESIGN Design a field study to include in the grant proposal Your proposal
should contain the following two sections
1 Study Design Construct and describe in detail an experimental or quasi-
experimental design to test the effectiveness of your intervention Describe in
detail the experimental groups (including how they will be constructed) the
research setting the sampling plan for study participants the treatment
manipulation and the data collection procedures Also indicate any control or
nuisance variables that may be measured
After describing the procedures write a justification of the design What threats
to validity does it rule out or limit and what threats to validity remain
II Measurement Describe the steps you would take to achieve valid and
reliable measure of the latent (conceptual) variable worker adjustment Your
team feels that as part of the proposal you must develop an original
operationalization of adjustment (thus you cannot simply use existing off the
shelf measures) Indicate in adequate detail how you would operationalize the
measure and indicate how you would demonstrate reliability and validity
B14 In describing their notion of the collective mind Karl E Weick and Karlene H
Roberts note Our focus is at once on individuals and the collective since only
individuals can contribute to a collective mind but a collective mind is distinct
from an individual because it inheres in the pattern of interrelated activities
among many people (p 360) Collective mind is not indexed by within-group
similarity of attitudes ideas or activities A collective mind is one in which
many people or many groups integrate their different attitudes ideas and
activities heedfully As Weick and Roberts note People act heedfully when
they act more or less carefully critically consistently purposefully attentively
studiously vigilantly conscientiously pertinaciously (p 361)
The idea of the collective mind as heedful interrelating is developed in the
following excerpt When people make efforts to interrelate these efforts can
range from heedful to heedless The more heed reflected in a pattern of
interrelations the more developed the collective mind and the greater the
capability to comprehend unexpected events that evolve rapidly in unexpected
ways When we say that a collective mind comprehends unexpected events we
mean that heedful interrelating connects sufficient know-how to meet situational
demands For organizations concerned with reliability those developments
often consist of unexpected non-sequential interaction (p366)
An example of heedful interrelating occurs as a pilot lands herhis aircraft on the
deck of an aircraft carrier The pilot does not actually land She is recovered
A recovery is an interrelated set of activities among air traffic controllers
landing signal officers the control tower navigators deck hands the helmsman
driving the ship etc These activities can be interrelated more or less heedfully
depending on the care with which the different units contribute represent the
situation and subordinate their activities to the single purpose of successful
recovery (p 363)
You are to design a two-part study
Part I You are to design a measurement study which assesses heedful
interrelating (ie collective mind) with a quantitative measure in a replication
of an aircraft carrier flight deck or other situation of your choosing Describe
your research strategies including operationalization of the variable selection of
the sample subjects data collection data analysis and so on for the purpose of
developing a measure of heedful interrelating
Part II Using the measurement tool developed in Part I and any other tools as
needed describe how you would design a study which would compare heedful
interrelating across organizations Choose at least one macro-organizational
variable (eg technology environment) as your basis of comparison Here you
must describe how you would make your selection of organizations to be
compared your data collection procedure data analysis and so on
B15 Many organizations in the United States have installed cross-functional teams to
counteract the silo mentality of traditional bureaucratic structure Preliminary
evidence of the effectiveness of cross-functional teams however is mixed --
some organizations have claimed success and others have reported failures The
evidence moreover is predominantly anecdotal--written for trade magazines by
the organizations themselves Since there have been few rigorous empirical
field studies assessing the effectiveness of cross functional teams the National
Science Foundation has decided to fund research on the topic
Assume that you are submitting a research proposal to NSF for a grant to
research the effectiveness of cross-functional teams Describe in detail and
thoroughly explain the research design sampling plan data collection
procedures ethical issues and proposed data analysis for your research design
Be sure to discuss the internal and external validity of your research Which
validity threats are ruled out and which remain NSF also requires that you
provide a statement and defense of the explicit philosophy of science underlying
your research Describe your philosophy of science and discuss how your
research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but
you must also demonstrate to NSF that you are a competent researcher It is
absolutely vital to NSF that the principal researcher (you) is knowledgeable
about the proposed research methodologies Therefore be sure that you always
carefully describe and give technical explanations for each component of your
research design and explain all technical terms (eg Cronbach alpha KR-20
Likert scale)
B16 Assume that you are submitting a research proposal to the Department of
Commerce (DoC) for a grant to research the effectiveness of virtual work teams
A virtual work team is a leaderless collection of individuals who are
geographically separate from one another and share their expertise using
internet media such as a listserver or Lotus notes The DoC requires that the
researcher use both qualitative and quantitative methods to gather data Describe
in detail and thoroughly explain the research design sampling plan data
collection procedures ethical issues and proposed data analysis for your
research design Be sure to discuss the internal and external validity of your
research Which validity threats are ruled out and which remain The DoC also
requires that you provide a statement and defense of the explicit philosophy of
science underlying your research Describe your philosophy of science and
discuss how your research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but
you must also demonstrate to DoC that you are a competent researcher It is
absolutely vital to DoC that the principal investigator (you) is knowledgeable
about the proposed research methodologies Therefore be sure that you always
carefully describe and give technical explanations for each component of your
research

that improves upon the key validity (or validities)
5 MEASUREMENT
A) Measurement Terms
A1 There are four levels of measurement rigor in management research Discuss each
one What properties do measurements at each level have (ie how much
information do the numbers from each level of measurement convey) How can the
numbers be changed (transformed) and still retain the properties of their
measurement level Pick one construct from a favorite research domain and give an
example of an operationalization of that construct at each of the four levels of
measurement rigor (provide arguments about why you think those examples reflect
each level) Lastly treat each examplelevel as a dependent variable in some
statistical analysis Given an example of a statistical technique appropriate for
analyzing data at that level of measurement rigor
A2 Define (and discuss important features or issues concerning) the following
constructs measurement (Define any six terms)
1 Construct validity 6 Item analysis
2 Likert scaling 7 Semantic differential
3 Cronbachs alpha 8 True score
4 Unobtrusive (trace) measurement 9 Generalizability theory
5 Interval scale 10 Criterion-related validity
11 Sociometric choice measures
B) Operationalization
B1 a) You are conducting a study which requires you to measure Hong Kong real
estate agents self-assessment of performance Since there is no existing
measurement available you have to develop the instrument by yourself
Describe how you would develop the measurement assuming that you have no
idea of how many dimension the construct has
b) Suppose you have developed an instrument consists of 20 questions
measuring 4 dimensions (5 items per dimension) from (a) You collected data
from another 300 real estate agents to validate your instrument Explain how
TH
you would use structural equations model (SEM) to examine the reliability and
validity of the instrument What are other concerns about reliability and validity
that are not addressed by this approach
B2 The research and business world have been fascinated with the concept of
organizational culture However operationalizing this construct has been a
difficult task Discuss the ways in which the construct has been operationalized
(eg technique static v dynamic sample selection generalizability) Critically
analyze each of these methodologies Then choose a methodology you would
use to examine organizational culture and defend your choice Describe how
you would study culture and what more would be known about culture as a
result of your study
B3 Suppose you are setting out to develop a new measure of a construct You want
this measure to be used in survey research and you want to establish its validity
and reliability Your goal is to have at the end of the process a measure that is
defensible and likely to be widely accepted by other researchers studying that
construct What steps would you take to conduct such a program of research
For each step explain the purpose of that step explain why that step is
important explain what methods and statistical procedures you would employ at
each step and explain what evidence you would hope to gather at each step
B4 Assume you are interested in constructing a new measure of (fill in with a
relevant variable from your field) Detail the major concerns that need to be
addressed and the steps that need to be taken in working toward validating this
new measure
B5 Assume that you recently read an article on workplace violence which you
found very interesting The authors argued that one of the predictors of
workplace violence was a construct called propensity to be violent and used a
one-item measure as follows How likely are you to become violent when
provoked You had serious doubts about the authors measure and decided to
develop your own
(a) How would you go about developing items to measure propensity to be
violent
(b) How would you determine whether the instrument was reliable
How would you determine whether the instrument was valid
B6 A concern in organizations is retirement of baby boomers within the next 5 -
10 years This concern is focused on the loss of older employees with skills
critical to the core business functions of organizations In order to continue to
have employees with those critical skills it seems necessary to retrain some
older workers However past practice in most organizations has been not to
retrain older workers for a variety of reasons mostly financial A researcher
working for the Human Resources Department of a large corporation - 13500
employees in 12 different plant locations - hypothesizes that the major reason
for not retraining older workers is ingrained in the culture of the corporation
IC
The researcher feels that older workers are not as highly valued as younger
workers in terms of their potential usefulness after retraining The researcher
searched the literature but found nothing in the existing literature to measure
the cultural value construct What should the researcher do to establish a reliable
and valid self-administered paper and pencil measure of this construct namely
the value of retraining older workers
a Please describe and explain the steps in temporal order that the researcher
must follow to develop a measure
b How would you evaluate the measure based on the technical requirements of
reliable and valid measurement as well as any practical issues in using the
measure considering the size of the employee population
B7 Assume that you are going to conduct empirical research to assess the role that
the complexity of an organizations manufacturing technology plays in
determining the level of centrality of decision making in the organization
Describe and justify the steps you might follow to develop an operationalization
of the concept of technological complexity What standards would you use to
determine if your operationalization is valid
B8 Organizational researchers have several strategies available to them for
gathering information (eg self-report measures archival measures direct
observation and trace measures) Assume that you are going to conduct
empirical research to assess the role that the structure of the organization plays
in determining the level of organizational effectiveness Briefly review the
strengths and weaknesses of the basic strategies (that is self-report measures
archival measures direct observation and trace measures) for measuring
organizational effectiveness Next describe and justify the steps you would
take to develop an operationalization of the concept of organizational
effectiveness What standards and procedures would you use to determine if
your operationalization is valid
B9 One of the most important topics of recent research has been stress in the work
place One of the most important problems with understanding this literature is
the varying definitions and measurement of this construct Suppose you had
decided to investigate the relationship between stress at the work place and dual
career family happiness
a Since there are multiple ways to measure stress in the work place describe
two ways to do this Hint - avoid using two self-report measures
b Describe how you would decide on the best single measure In doing so
describe the steps you would take in evaluating your measure Be sure to define
your meaning of validity and reliability It is important that your measure have
all the necessary psychometric characteristics so that other scientist can trust the
results of your research
c Be certain that you answer the question Validity for what
d In order to understand the results of your study you need to compare your
measure of stress at work with other measures of this construct How would you
do that
B10 Assume that you have been hired by a national survey research company
Shash Inc to write items that will be used in a national survey of attitudes
toward capital punishment There are a number of criteria that can be used to
guide your item writing What are they Briefly describe five (5) such criteria
B11 Assume that you are going to conduct empirical research to determine the
impact of interpersonal trust on organizational decision making Describe and
justify the steps you might follow to develop an operationalization of the
interpersonal trust concept
B12 Assume that you are going to conduct empirical field research to assess the role
that employee empowerment plays in determining the level of organizational
commitment of employees Describe and justifyexplain the steps you would
follow to develop a valid and reliable operationalization of the concept of
employee empowerment
Explain the procedures and standards you would use to determine if your
operationalization is valid and reliable
How would you assess the construct validity of such a measure
Discuss issues concerning the level of observation of your measure and level of
analysis of the data
B13 Assume you are interested in developing a new scale to measure construct X
Further assume that you have used previous literature and your own conceptual
development to delineate 2 dimensions of X specifically XF1 and XF2
Describe the steps you would go through in developing testing and evaluating
this new scale With regard to testing and evaluating be sure to consider the
role of factor analysis (both exploratory and confirmatory) and item analysis
Also you will want to make sure that your new multidimensional scale shows
evidence of validity (several kinds) and reliability so be sure to examine these
issues and explain how specific information gathered from the above testing
contributes to these concerns
C) Reliability
4) What is reliability and why is it so important What are the different ways reliability can be
assessed and when is each appropriate
15) What does coefficient alpha assess What are the ways coefficient alpha can be increased
C1 Describe and discuss the concept of reliability and all of its various forms
including their assessment When is each form appropriate and what information
is provided by each index
C2 In establishing congruence between multiple measurements we often compute
indices of reliability andor indices of agreement These two types of indices
address very different questions Your task is to 1) Define reliability and
agreement 2) Explain when each is useful using examples in which one but not
the other is appropriate and 3) Briefly describe two reliability indices and two
agreement indices
C3 Explain reliability in terms of the classical test theory What are the
consequences of unreliable measures in hypothesis testing What are the factors
that may affect the reliability of a multi-item scale
IC
C4 Generalizability theory is used within IO psychology more often today
However most researchers continue to use Classical Test Theory
conceptualizations of error to determine reliability What are the implications of
using classical test theory versus generalizability theory to assess reliability
C5 In establishing congruence between measurements we often compute indices of
reliability andor agreement Define reliability and agreement Explain the
differences in reliability and agreement and describe under what conditions
assessing reliability is more appropriate and under what conditions assessing
agreement is more appropriate
C6 Define measurement reliability in terms of a specific measurement theory (eg
true test score theory domain sampling theory generalizability theory IRT)
Discuss the different approaches for estimating reliability and the contexts in
which each might be appropriate Use examples throughout
C7 What are the consequences of unreliability in a measure
C8 What are some of the conditions that might keep the internal consistency (eg
alpha) of a given measure low Is a low alpha always a sign of a problematic
measure
C9 Define reliability Name some methods of calculating reliability How well do
these methods map up with the definition of reliability What is the impact of the
number of test items and sample size on Chronbachs alpha and why would this
effect occur or not occur (Note Do NOT discuss inter-rater reliability)
C10 Schmidt and Hunter (1996) described several types of measures typically used in
organizational research and identified the type(s) of measurement error affecting
each of them in various situations For each measure below indicate the types of
error and sources of error that are most likely to affect it Then indicate what
could be done to reduce errors of measurement andor what can be done to
control for errors statistically
a Supervisor ratings of subordinates job performance
b Self-ratings of ones own job performance
c Self-reports of ones own job-related attitudes
d Sales figures for a salesperson (or production quantity for a production
worker)
d Aptitude tests taken as part of the hiring process
C11 Suppose you had conducted research on the relationship between organizational
commitment and rigidity of organizational structure in 200 firms Your measure
of rigidity was based on number of organizational authority levels and the degree
to which written organizational rules existed and defined role behaviors for
employees Thus an organization with a large number of organizational levels
and specific written policies defining appropriate role behaviors for employees
would score high on rigidity of organizational structure After analyzing your
data you find that there is a statistically significant negative correlation between
commitment and rigidity which is consistent with your hypothesis However the
reliabilities for your two measures are
(1) commitment = 23 (2) rigidity = 83
How should you interpret your results What could you do to fix this situation
Describe the specific steps (in order) you would follow to develop a more
reliable measure of commitment
C12 (a) Define the concept of reliability (of measures) in a clear concise and
accurate manner (b) Provide a formula that expresses the reliability of a measure
in terms of two components of variance ie total variance and the error
variance
D) Multi-level Assessment
D1 One of the major challenges for group-level research is the issue of aggregation of
individual data to the group level
(a) Under what conditions (eg types of data number of raters) should the various
interrater agreement and reliability methods be used (Rwg Kappa and Weighted
Kappa percent agreement average pairwise correlation ANOVA methods
(interclass correlation coefficient WABA)) What are the advantages and
disadvantages of each of the methods
(b) Explain the controversy between Frank Schmidt Larry James and others
regarding the differences between interrater agreement and interrater reliability
Who is right Do the differences matter in research practice
Defend your answers
(c) Review two articles from the organizational behavior literature that have had to
deal with aggregation issues Critique the methods the authors used to make
aggregation decisions
(d) Provide some advice to researchers regarding what they should do if interrater
agreement and reliability indices indicate that it is not legitimate to aggregate their
data
(e) Provide some ideas for avoiding the need to aggregate in group-level research
through creative research methods and measurement strategies
D2 Cross-levelmulti-level research is becoming more evident in the organizational
research literature This type of research raises many issues and presents many
challenges in terms of designing the research measuring variables and collecting
and analyzing the data Assume that you are interested in aggregating data (eg
from the individual to the group or from the firm to the industry) for one or more
variables What are the major issues you will need to deal with
D3 A researcher wants to measure organizational climate for continuous learning
Organizational climate is operationalized as a shared consensual aspect of the
organization -- the shared perception among employees that the organization values
and supports continuous learning Describe how you would measure organizational
climate in this case Specify (a) the level (ie individual group organization) at
which the construct exists (b) the level at which you would measure the construct
and (c) the procedures that you would use to establish that measurement is aligned
with theory (ie the construct validity of the measure)
E) General (Measurement)
E1 Studies in organizational behavior research often rely on single-item measures of
key constructs The use of single-item measures has long been criticized based
on the premise that single-item measures are unreliable However Wanous
(Wanous amp Hudy 2001 Wanous amp Reichers 1996 Wanous Reichers amp Hudy
1997) has recently argued that single-item measures can exhibit adequate
reliability Wanous based this conclusion on a procedure for estimating the
reliability of single-item measures using the classic formula for correction for
attenuation Subsequent studies have yielded mixed results regarding the
conclusions of Wanous (eg Loo amp Kells 1998 Nagy 2002) and the veracity
of the perspective advocated by Wanous remains in question Summarize and
assess the arguments for and against the use of single-item measures and
evaluate the procedure and evidence offered by Wanous regarding the reliability
of single-item measures Based on your assessment and evaluation develop
recommendations regarding the use of single-item measures in organizational
behavior research

E2 Ipsative measures have become prevalent in organizational behavior research
Ipsative measures ask respondents to answer questions relative to one another
such that the scores for all questions sum to the same constant for all respondents
Examples of ipsative measures include rankings Q-sorts and the allocation of a
fixed number of points (eg 100) across a set of response options Ipsative
measures may be contrasted with absolute measures which ask respondents to
answer questions independently from one another Absolute measures are
exemplified by rating scales using an interval or ratio numeric response format
The relative merits of ipsative and absolute measures have been debated for
decades (eg Cornwell amp Dunlap 1994 Hicks 1970 Johnson Wood amp
Blinkhorn 1988 Saville amp Wilson 1991 1992) yet the fundamental issues
underlying this debate have not been adequately addressed in organizational
behavior research For example measures of organizational culture and values
are often ipsative and some researchers advocate these measures over absolute
measures (eg Meglino amp Ravlin 1987 OReilly Chatman amp Caldwell 1991
Ravlin amp Meglino 1987 see also Rokeach amp Ball-Rokeach 1989) Review the
relative merits of absolute and ipsative measures Based on your review which
form of measurement is most appropriate and why Do your conclusions depend
on the construct being measured If so what types of constructs are best suited to
ipsative measures and what types are best suited to absolute measures Next
apply your conclusions to the measurement of culture and values in
organizations What specific arguments have been advanced in favor of ipsative
measures of culture and values How sound are these arguments Should ipsative
measures be used in the study of organizational culture and values If not how
can absolute measures of culture and values be developed that address the
concerns voiced by advocates of ipsative measures Provide a specific example
of the type of measure you would propose

E3 In organizational research measures often consist of items that represent different
facets of a concept Although such measures are prevalent and in some cases are
advocated (eg Law et al 1998 1999) they can present a variety of conceptual
and methodological problems Describe the specific problems associated with
measures that use items representing different facets of a concept Compare these
problems with the purported advantages of such measures Conclude by

E5 Suppose Roberta Von Eisenbrick is a researcher interested in the consequences of
AFFECTIVE CONFLICT (AC) in decision-making teams She gets access to a
variety of outcomes assessment committees at each of 87 different schools in
the Dallas Independent School District and gains permission to tape-record two
of their meetings (one in February and one in March) Such committees have
been formed to develop quantitative ways to track pursuit of school goals and
provide accountability to local and state governments These are often divisive
teams with heated meetings because what gets assessed is what usually gets
rewarded After both of these meetings the committee members each
fill out a short questionnaire that contains 20 Likert-type items measuring how
much AC occurred (eg People in our group often get angry with each other)
The individual scores are summed across items then averaged across team
members to come up with a group-level AC score for each of the 87 2
meetings The same procedures are followed for a 5-item measure of Group
Cohesiveness (GC) which is predicted to be reduced by higher levels of AC
Roberta also listens to every tape and from her expert judgment she rates each
groups meetings on the same 20 items Those 20 ratings are summed for each of
the 87 2 meetings Now Roberta is interested in evaluating her measure She
wants it to have excellent psychometric properties including reliability and
construct validity

D) ModeratorsMediators
D1 Moderation and mediation provide different ways to model third variable effects
(a) Please define both of these terms (b) Sketch a conceptual model to show how
each relates to main effects (c) Using variables of your choice please write
hypotheses to reflect both (d) Explain how each is tested analytically
D2 Discuss moderators and mediators Provide an example of how (1) a moderating
variable influences the relationship between the independent and dependent
variable and how (2) a mediating variable influences the relationship between
the independent and dependent variable Describe how you would test for both
moderation and mediation using regression
D3 Many theories in organizational research predict that the effects of one variable
on another are moderated by a third variable Such moderator effects are
typically tested by entering the product of two variables as a predictor after
controlling for the two variables that constitute the product Several researchers
have pointed out that this product is often highly correlated with the squares of
the two constituent variables and have suggested that moderating effects may be
tested after controlling not only for the two constituent variables but also their
squares (eg Cortina 1993 Ganzach 1998 Lubinski amp Humphreys 1990
MacCallum amp Mar 1995) Discuss the strengths and weaknesses of this
approach as compared to methods that use only the product term and its
constituent variables Conclude with recommendations as to when and under
what conditions organizational researchers should test moderator effects with the
squares of the constituent variables in the equation

D4 Assume you are interested in studying relationships amongst three variables X
Y and Z Your first hypothesis posits Z as a mediator of the relationship between
X and Y Your second hypothesis posits Z as a moderator of the relationship
between X and Y Draw the figures depicting each of these hypothesized
relationships and describe (make sure to write regression equations) how you
would test each of these hypotheses
D5 The amount of time and effort that the average person pours into his or her job
has risen steadily over the last two decades such that the average person now is
working one more week per year than the average person in the mid 1970s This
steady increase has fueled research interest in the construct of Job Burnout (JB)
which is an emotional and physical exhaustion associated with ones work
Organizational Stress (OS) the perception of greater demands than available
resources in ones work environment is thought to be one of the chief
antecedents of JB However time spent under OS is thought to make its affects
on JB accumulate or worsen Work Role Withdrawal (WRW) the avoidance of
responsibilities or the deliberate reduction of inputs to ones job is believed to be
the chief consequence of JB
a Formally state these ideas as verbal hypotheses as equations and as a complex
directed graph (circle amp arrow diagram)
b Conceptually what is a mediator Define the term and identify the mediator in
your hypotheses in (a) What elements or steps in a study design (not statistics)
that would be helpful for detecting the mediating relationship that was proposed
c What is a moderator What are some of the other names for it within various
subdomains of management Further demonstrate your understanding of
moderator variables by picking which variable in (a) is the moderator Show the
moderating relationship in an X-Y (or multi-layered) chart Again what elements
or steps in a study design (not statistics) would be helpful for detecting the
moderating effect implied above

E1 In your role as professional colleague you are called upon to advise another doctoral
student about the appropriate use of multiple comparisons and post hoc tests in
analysis of variance Your student colleague already has been introduced to ANOVA
and multiple regression Specifically you are to write out a description of how to test
for differences among the different levels or cells of a categorical variable In your
description you should discuss among other things
a the statistical and philosophical issues raised by post hoc analysis and data
snooping

recommendations You conduct a well-designed controlled study (details are unimportant) and discover students who use the new book perform 10 better on a standardized subject
matter exam than those using the old book (p = 027) Both books are readily availabe their prices are almost identical and both are equally acceptable to the instructors What is your recommendation to the chair
F1 Attached is the beginning of an article Your task is to write the results section by
1 making up and reporting plausible descriptive statistics that will help the
reader understand the results of the statistical tests you report and the nature of your
sample (Hint this can be presented in the form of a table)
2 describing and defending your choice of appropriate statistical tests of the
hypotheses and the steps that you would go through in carrying out these tests
3 making up and reporting results of these tests that are consistent with your
descriptive statistics and with any information in the rest of the article about the
results found (Hint this can be presented in the form of a table)
4 describing how well these results provide support for the hypotheses You
may want to note any relevant threats to validity here
Be sure to state any assumptions you make
F2 Assume that the Personnel Manager of a local firm Ms B dFlandres hired you to
analyze some data that her assistants had collected over the past several years The
data consist of (a) job performance ratings that were made in June of 1990 and (b)
scores on 25 predictor variables (eg measures of education job experience job
tenure job aptitude personality) that were measured when the individuals were hired
(between April 1987 and May 1988) She had data from only the 110 subjects (60
males and 50 females) who were hired during the period and were still employed by
the firm One objective of your analysis (analyses) is to determine how well the
performance criterion can be predicted by the predictors What strategy would you
use in analyzing the data Describeexplain (b) Is sample size an issue for your
analyses Explain If it is what will you do to deal with problems stemming from
sample size Assume that no additional data can be collected at this time (c) Some
preliminary analyses that you do reveal that five of the predictor variables correlate
(zero-order basis) about 75 with one another Will this influence the analyses that
you use Will it influence the validity of conclusions derived from your proposed
analyses (d) Ms dFlandres is interested in knowing if the predictor variables are
equally effective in predicting the job success of males and females What analysis
or analyses would you do to deal with this issue
F3 Assume that you have been provided with data on 12 conceptually distinct variables
that are moderately correlated with one another at the empirical level The data are
from students in four different college majors ie astronomy (A) biology (B)
criminology (C) and demography (D) The 12 measured variables fall into the
general categories of mental health (tension emotional withdrawal hallucinations
guilt feelings blunted affect and suspiciousness) and job satisfaction (work itself
supervision co-workers pay promotion prospects and working conditions) Your
task is to determine if the individuals in the four college majors differ from one
another on the 12 measured variables
(a) What statistical technique(s) would you use to test for group differences
Explain Be specific about the procedures(s) that you would use
(b) What statistical estimate would you use to estimate the extent to which the
groups differ from one another Be specific
F4 The following statistical table published in a recent issue of Work amp Occupations
was taken from an article discussing variables influencing resistance and citizenship
behaviors in the workplace Resistance behaviors include playing dumb withholding
effort work avoidance subverting particular managers and sabotage Citizenship
behaviors include cooperation engaging in peer training use of insider knowledge to
facilitate production commitment to organizational goals giving extra effort freely
Both measures are global constructs aggregated to the interval level and
standardized
The table reports the results of a series of ordinary least squares regression equations
with standardized coefficients Explain the meaning of the statistics presented What
do these statistics tell us generally about the relationship between resistance
behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows
Anomie Index -standardized interval level measure tapping multiple dimensions
The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)
F5 Researchers collected data from a sample of 350 companies on the following
variables
size (measured as number of employees)
Business Strategy (a nominal variable with 2 response options low-cost provider or
differentiator)
HR Strategy (a nominal variable with 2 response categories High commitment or
low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

measures is the multi-trait multi-method matrix developed by Campbell and
Fiske (1959) Briefly describe how this matrix is obtained or constructed by a
researcher and then describe how each of the elements of the matrix is used to
demonstrate the reliability andor construct validity of the measure(s)

and discuss the assumptions of the general linear model Multiple regression
ANOVA and principle components (factor) analysis are based on the general linear
model For each of those three statistical procedures describe and discuss the

assumptions usage and limitations
O3 How do exploratory and confirmatory factor analysis differ What are the
advantages and disadvantages of each
O4 Describe the differences between exploratory factor analysis (EFA) and
confirmatory factor analysis (CFA) When would you use one verses another
Are there ways to use EFA in a confirmatory way Can you use CFA in an
exploratory way Also describe the difference in principal components analysis
(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression
O6 The basic factor analysis model can be represented by the matrix algebraic
equation A B = C
(1) What do each of these matrices represent Be specific as to the type of
information in each matrix and its purpose
(2) For what purpose do researchers use factor analysis Explain In the process
provide a very brief description of a study for which factor analysis would be a
useful data analytic technique
O7 Factor analysis is an important statistical technique in organizational research
Describe factor analysis as an analytical tool including the following issues
a the reasons for using factor analysis
b the type of data necessary for using the technique appropriately
c the type of quantitative output that results from applying the technique
d how a researcher would use the output in his or her research
e how confirmatory factor analysis is different from exploratory
f the important issues and problems in using the technique
P) Structural Equation Models
P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)
Please comment on these restrictions versus access argument Which side do you
take
What are the strengths of SEM Give some examples
What are the weaknesses of SEM Give some examples

B) Level of Analysis
B1 IO psychologists have traditionally categorized themselves as being more micro or
macro in orientation usually falling toward the micro end Recent concern for what
has been termed the levels of analysis or cross-level approach has added a third
category - meso What is the meso level Is this just academic hairsplitting or re-
naming or is there a fundamental difference in this research strategy in contrast to
micro or macro Provide an example from some research domain of interest to you
that illustrates your conclusion of no real difference or important difference
C) Cross-Sectional vs Longitudinal Design
13) What are the benefits of a longitudinal design over a cross-sectional design in a non
experimental (correlational) study What are the disadvantages Why donrsquot we see
more longitudinal research
C1 The use of cross-sectional research designs continues despite many calls for
replacing them with longitudinal designs (a) What are the main strengths of
cross-sectional designs (b) What weaknesses do they have that longitudinal
designs supposedly counter (c) What are the implications of cross-sectional
designs for theory development (Consider internal and external validity)
C2 A good number of research efforts on the micro (OBHR) side rely on cross-
sectional designs in which surveys are used to collect both IVs and DVs from the
same respondent What are the various problems associated with such a design
What changes could be made to this design to alleviate andor eliminate these
problems What are the downsides of the new design (add in conveniencenon
probability samples)
C3 What are some of the major strengths of a longitudinal design Why dont we see
more of them
C4 Assume that you are analyzing a large sample of longitudinal survey data TH
Identify two characteristics of your data that would make ordinary least squares
regression (OLS) inappropriate for conducting analyses For each of these
characteristics describe an alternative analysis that is superior to OLS
D) Qualitative vs Quantitative Designs
D1 Compare and contrast the objectives strengths and weaknesses of
qualitativeobservational methods (eg ethnography) versus quantitative methods
(eg survey) in conducting empirical research on macro organizational issues Be
sure to consider issues of reliability generalizability validity ethics and
practicality in your answer Describe situations where one method or the other
may be most appropriate
IC
D2 In recent years a number of individuals have taken the position that qualitative
research is superior to quantitative research a Compared with quantitative
research what are the principal strengths of qualitative research b Compared
with quantitative research what are the principal weaknesses of qualitative
research
E) Observation vs Experiment
E1 Compare and contrast the objectives strengths and weaknesses of observational
methods (eg ethnographic methodology) and experimental methods Be sure to
consider issues of precision generalizability and realism in your answer Consider
also situations where one methodology or the other might be most appropriate
F) Laboratory vs Field Research
F1 Of the various research approaches available to organizational researchers
laboratory experiments are held up as an ideal because of their potential for high
internal validity On the other hand field research including participant observation
and field experiments have high potential for external validity Discuss specifically
the strengths and weaknesses of laboratory versus field experiments How would
positivist researchers think differently about these tradeoffs than would
phenomenologists
F2 In conducting an experiment in the laboratory or designing survey research there are
certain unique opportunities and limitations of each research strategy A) Describe a
hypothesized relationship between two constructs an independent and a dependent
variable in a substantive area of your choice (eg Strategy OB HRM
Organizational Theory) provide a verbal mathematical and graphical statement of
that hypothesis B) Briefly discuss how you would examine this hypothesized
relationship in a laboratory using experimental techniques versus a field survey using
correlation techniques C) Discuss what may be considered typical strengths and
weaknesses of each strategy regarding issues of precision and control in the
manipulation or measurement of the variables of interest realism of the context for
the participants and generalizability of the findings to other elements of a chosen
population D) Finally discuss advantages if any of using laboratory and field
survey methods in tandem
G) Experimental Design
2) A colleague suggests to you that only true experiments can provide useful results in
science Why might she say this What would you offer as a defense for the role of quasi-
experimental and non experimental designs in the context of the social science In
answering this question make sure you identify the defining characteristics of each design
type
9) Why and when should we be concerned about non response in research What are the
things we can do to try and decrease non response (or increase response rates)
11) Why might a researcher choose to utilize an experimental design that incorporates pretest
measure on the DV
G1 Experimental designs oftentimes come under attack due to perceived limitations in
external validity (a) Relative to other design types what strengths and weaknesses
do they offer (b) What experimental design structure is the strongest Why (c)
What is the relevance of research design for results and theory development
G2 Meta-analysts often investigate whether the quality of research design (eg
randomized experiments vs non-randomized designs) influences average effect
size In their meta-meta analysis of psychological educational and behavioral
treatments Lipsey and Wilson (1993) found that In a given treatment area poor
design or low methodological quality may result in a treatment estimate quite
discrepant from what a better quality design would yield but it is almost as likely
to be an underestimate as an overestimate (p1193) A few methodologists (eg
Shadish) have attempted to identify factors that may explain the relative magnitude
of effect sizes from randomized and nonrandomized experiments Please review
these findings and add your tentative model of the conditions under which random
experiments will produce larger smaller or equal effect sizes relative to
nonrandom designs Discuss possible implications for research design in the
context of real-world interventions
G3 Analysis of covariance and randomized blocks designs are sometimes referred to as
noise-blocking designs Explain what this means and give an example of (a) a
randomized blocks experiment and (b) an analysis of covariance experiment Keep
your examples simple Describe how such designs are noise-blocking when used
with randomized assignment of subjects to experimental condition and contrast
that with the role such designs serve in quasi-experimental designs
G4 Team performance in Bafko Industries varies considerably across teams and from
month to month The senior VP in charge of team development thought that a team
training program could improve the performance of these teams A consultant
convinced him that his firms training program which lasted only one week and
cost only $25000 per team) could raise the performance of Bafkos teams The VP
however wanted to experimentally test the efficacy of this training program before
he adopted it widely throughout the firm So the consultant suggested the following
experimental test
There were 48 teams in Bafko that showed significant variation from month to
month in their level of performance The consultant chose the 24 worst performing
teams based on last months data and assigned them to the training group After
all he argued these were the ones who most needed it The other teams were
assigned to the control group The training group received the training program
(lasting one week) at the beginning of the next month while the control group
teams did their normal routine Performance scores were gathered at the end of the
month The results showed that the training group teams had a significantly larger
rise (ie statistically significant) in their performance than did the control group
teams (who as a group did not improve at all) The consultant proudly displayed
these results and argued that they convincingly demonstrated the efficacy of his
program
How would you advise the VP Specifically what is the validity of the consultants
conclusions If you think he might be mistaken what specific threats to internal
validity are particularly plausible
G5 Consider the following design
N O Xa O
N O Xb O
N O Xc O
N O O where
Xa Xb and Xc represent different levels of a training program that varied in its
length across three different work groups In group a the training time was 40
hours in group b it was 30 hours and in state c it was 20 hours The training was
designed to instill customer service values in the team members O represents a
measure of customer service attitudes measured with a 20-item Likert scale This
measure was administered one week before the training program and 3 months
later The researcher hypothesized that the training program would improve
customer service attitudes and that longer training would have stronger effects
The design is a non-equivalent groups design because people were not randomly
assigned to groups even though groups were randomly assigned to treatment
condition Each group has a sample size of 36 members The reliability of the
customer service attitude scale was 78 at the pretest and 80 at the posttest The
pretest means were as follows
Group A 26
Group B 23
Group C 27
Control Group 25
a Construct a regression model that will test the researchers hypothesis Be
explicit here describing each variable in the model and what regression effect(s)
you would expect to find if the hypothesis were correct (Hint everything you need
to know is in Trochims chapter 11 and what we discussed in class) (10 points)
b Describe any serious threats to internal validity (10 points)
c Discuss how you might amend this design to improve its internal validity(10
points)
G6 Often in organizational research the researcher is faced with having only one group
on which to experiment and thus cannot use a control group when conducting
experiments This occurs for example in taxation experiments when you cannot
selectively apply new tax laws to different groups or when you wish to test the
efficacy of an incentive plan that must be applied to all members of a company In
such situations the researcher must be creative in assembling a quasi-experimental
design that has high validity (and usually the challenge concerns internal validity)
Consider the following scenario
A manager of a retail store wants to test the efficacy of an incentive program in
changing the selling behaviors of her retail sales clerks Specifically she wants to
test a behavioral reinforcement program in which sales peoples behavior is
recorded on in-store video cameras The tapes are analyzed each night and the
experimenter tabulates the frequency of various behaviors (eg offering assistance
to customers restocking items straightening up displays suggesting accessory
items to accompany the items that a customer is purchasing) The manager then
rewards the clerks with a monetary bonus based on the frequency of desired
behaviors She would like to conduct a valid experiment to see what effect such an
incentive program has on employee behavior but because of concerns about
employee morale she cannot assign clerks to treatment and control groups Instead
she has to apply the experimental treatment to everyone in the store She learned in
her research methods class (which the company requires all its managers to take)
that a single group experimental design typically has very low internal validity
Your job as a consultant is to help her design an experiment given her constraints
that would produce interpretable (ie internally valid) results Describe the details
of the design you would recommend using the notation in Trochim (2001) If the
design you come up with has a specific name use it As part of describing your
design discuss how the data would be analyzed and what particular effect you
would look for
G7 Why are experimental research designs held in such high regard
G8 Compare and contrast experimental quasi-experimental and correlational research
designs What characteristics separate these three designs What are their
advantages and disadvantages especially in comparison to one another
G9 What is the difference between a within-subjects experimental design and a
between-subjects experimental design When might a within-subjects design be
appropriate When might it be inappropriate
G10 Describe the difference between a basic within subjects and between subjects
experimental design What are the advantages and disadvantages of each
especially in comparison to one another Give an example from your area of
research in which each would be appropriate
G11 What are the major threats to the internal validity of a pretest - post test
nonequivalent control group design How can this design be improved with regard
to increasing a researchers ability to make causal inferences
G12 A production manager is interested in testing the hypotheses that participation in
quality circle programs will result in increased productivity and reduced
absenteeism A questionnaire is administered to a group of 92 employees
concerning their attitudes toward such programs and 46 with the most favorable
attitudes who are willing to participate are selected for the treatment group The
remaining 46 are the control group Measures of performance (unitsmonth for the
group) and absenteeism (lost daysmonth for the group) are kept over a three month
period during which the treatment group has weekly quality circle meetings The
results are as follows
Month 1 Month 2 Month 3 Month 1 Month 2 Month 3
Performance Absenteeism
Treatment 100 115 121 6 9 4
Control 110 108 113 6 8 5
The manager calculates t tests between month 1 and 3 The only significant
difference is performance for the treatment group so the manager concludes that
quality circles raise productivity but do not have an effect on absenteeism What
are the primary threats to internal and external validity in this study What are
possible alternative explanations for the differences (or lack of differences)
between the two groups What additional information might help explain these
results
G13 One stream of current strategy research contains event studies In these studies
investigators basically correlate the reaction of a financial market to the presence
andor absence of the occurrence of some event at a firm (eg the resignation of a
CEO) In a different approach to such a study suppose that one investigator (Jean)
conducts a natural field experiment on the effects of competitor mergers on a
firms environmental scanning activity Through previous arrangement Jean has
been working with 5 medium-sized computer hardware and 5 medium- sized
software firms on the west coast Shes been collecting a paper trail of internal
memos reports and phone calls that might measure environmental scanning
activity Shes been finding that the firms in both industries do about the same
amount of scanning (no significant differences) However in the midst of her data
collection Norton announces a merger with Symantec (software) A year later
Jean compares the amount of post-merger environmental scanning in the software
industry with that in hardware industry Just as Jean had hypothesized a t-test
shows a greater amount of post-merger scanning among the software firms She
concludes that her hypothesis was supported mergers of competitors cause an
increase in scanning
Critique the study described above in terms of its design flaws Identify the design
Jean used Briefly allude to problems the study has with external validity but
concentrate on the Cook and Campbell threats to internal validity Provide a
rationale for why each threat is or isnt operating in the study Link each of the
relevant threats to the specific constructs being studied (mergers and environmental
scanning) Finally do a summary evaluation -- what can be learned from this
study
H) Quasi-Experimental Design
H1 The University of Mississippi observed that the graduation rate of students with poor
grades during their freshman year was much lower than those with better grades
Wanting to improve the chances of these low performing students they tested the
effects of a new rule for freshmen The rule stated the following At the end of their
first semester all students with a GPA between 200 and 225 must register for
EDUC 1003 during their second semester Students with a GPA lower than 200
were put on academic probation EDUC 1003 consisted of a course whose objective
was to help students develop good study skills The theory was that poor study skills
were a significant cause of poor academic performance and that study skills could
be learned
They wanted to evaluate the effectiveness of this intervention so they collected data
on the GPAs of students beginning with their first semester and continuing through
to their third semester At that point they wanted to analyze the data to determine
whether the new rule was making a significant difference in the students academic
performance
What is the best way to analyze these data to reach an interpretable conclusion
Describe your approach and then discuss the major threats to validity that it has
Their sample size of students was as follows
Total N= 3454 (these are students who completed all 3 semesters)
Number of students with first semester grades between 200 and 225 (and thus took
EDUC 1003) was 956
H2 A nationwide furniture company wants to determine if a diversity training
program will improve individual sales performance on the floors of its urban retail
outlets A group of 45 salespeople in one city were given two weeks of training
Measures of individual sales performance were taken once two months prior to the
program and once two months after Forty-five salespeople (who did not receive the
training) in a similar city had the same measures taken at approximately the same
points in time The training group increased their average weekly sales from $14000
to $16500 while the non-training group improved theirs from $13000 to $14500
The change for the training group is statistically significant the change for the non-
training group is not
How would the interpretation of these results in this quasi-experimental design
differ from a true experimental design What are the threats to internal validity in
the above study and how might they be operating (be specific) What additional
information and analyses would be useful in controlling for these threats
H3 An accounting firm is interested in determining if a re-training program will reduce
errors made by its audit teams A group of 45 auditors in the home office location
are given two weeks of re-training Measures of the frequency of detectable errors
are taken once two months prior to the program and once two months after Forty-
five auditors in similar office at a branch location have similar measures taken at
approximately the same points in time The training group reduced their average
number of errors per audit from 8 to 3 while the non-training group reduced theirs
from 11 to 9 The change for the training group is statistically significant the change
for the non-training group is not
How would the interpretation of these results in this quasi-experimental design
differ from a true experimental design What are the threats to internal validity in
the above study and how might they be operating (be specific) What additional
information and analyses would be useful in controlling for these threats
H4 Describe the main classes of threats to validity that are found in quasi-experimental
research designs
H5 Dr Delta an organizational development consultant was hired by a firm that has
600 pizza parlors nationwide to assist in implementing organizational changes that
he hopes will result in higher levels of job involvement At the outset of the study
subjects had jobs with very low levels of enrichment and were paid on an hourly
basis He designed an experiment in which stores were randomly assigned to one of
three treatment conditions Condition 1 subjects experienced job enrichment (JE)
and a change to performance-based pay (PBP) Condition 2 subjects experienced
only JE and Condition 3 subjects experienced only PBP The parlors were
sufficiently far apart from one another and communication among the parlors so
poor that subjects in any parlor were totally unaware of changes made in other
parlors At the end of 18 months he measured the job involvement levels of workers
and then tested for differences between the three conditions using a standard one-
way analysis of variance In view of Dr Deltas design answer the following
questions
How sound is Dr Deltas design Comment on the weaknesses of the design
I) Interrupted Time Series Design
I1 What threats to internal validity are and are not ruled out by an interrupted time series
design that includes the introduction of a treatment and its removal at a subsequent
time period List and explain In the process be certain that you provide a diagram
that illustrates such a design
J) Validity Some Questions are about the validity of a measure others about experimental validity)
10) Identify four threats to internal validity and briefly describe what they mean
J1 It was some time ago that the tripartite view of validity was abandoned in favor of a
unitarian view in which different evidentiary bases for validity might be put forward
Binning amp Barrett (1989) represent an attempt to place multiple evidentiary bases into a
single framework Cook amp Campbell (1979) describe four aspects of validity but they
arent really meant to represent evidentiary bases Adding to the confusion is the fact
that while Binning amp Barrett and Cook amp Campbell use some of the same terms these
two pairs of authors clearly mean different things by these terms and intend for them to
be used in different ways Your task is to 1) Describe the evidentiary bases discussed
by Binning amp Barrett 2) Describe the aspects of validity described by Cook amp
Campbell 3) Describe the similarities and differences between the two lists including
the different purposes served by the two lists and 4) Present a single framework that
incorporates both This last task is the most important of the four
J2 What are the types of validity How would each affect an empirical study IC
J3 Define both internal and external validity Which is more important (it is not okay to
say that they are equally important) Defend your reasoning
J4 Why might someone argue that the construct validity of a measure can never really be
established
J5 Describe each of the following forms of validity content convergent discriminant
criterion-related and construct How is each assessed How do they related to each
other Which is most important (Make sure you defend your answer)
J6 Define and explain 6 of the 8 types of validity listed below and describe the type(s) of
information each provides Choose one specific type of study as an example (eg
cross-sectional study experiment quasi-experiment simulation ethnography etc) and
compare and contrast the usefulness and importance of each type of validity for that
type of study
-- Concurrent validity
-- Construct validity
-- Content validity
-- Convergent validity
-- Discriminant validity
-- Statistical conclusion validity
-- Internal validity
-- External validity
J7 Designing empirical research has been called making a series of trade-offs
Unfortunately decisions that are made to increase one desired quality (like internal
validity) can also decrease another desired quality (like external validity) For each of
the issues below discuss the concerns involved (ie the trade-off) and identify the
qualities that are being increased or decreased
a laboratory vs field study
b using a 5-item measure vs a 1-item measure
c using a student sample vs a sample of full-time employees
d using a sample of employees from one company of 5000 vs 500 employees from
each of 10 companies
e collecting your data using one method vs collecting your data using multiple
methods
J8 There are four major types of validity in social science internal validity external
validity construct validity and statistical conclusion validity Please address the
following three issues concerning validity
a What is the meaning of the four major forms of validity (ie internal and external
validity construct validity statistical conclusion validity)
b Are there trade-offs that can or must be made among the four types of validity
d Describe how the concept of validity varies across the research traditions of
experimental vs observational research
IC
J9 The quality of research is often assessed by examining validity issues As you are
aware there are numerous typesforms of validity (eg internal and external validity
construct validity statistical conclusion validity) These types of validity address
different aspects of the research process For this question please address the following
issues
a What is the meaning of the four major forms of validity (ie internal and external
validity construct validity statistical conclusion validity)
b Should there be a priority among these forms of validity If yes why If no why not
c Does the concept of validity vary across research traditions (ie experimental vs
observational research) If yes why If no why not
J10 External validity has received considerable attention in the social and behavioral
sciences Some researchers argue we are too concerned with the external validity of our
findings while other researchers argue that we are too unconcerned with external
validity Several points of view have been developed to explain what is external
validity When answering this question please be sure to address at least the following
issues
a Compare and contrast alternative conceptualizations of external validity
b Some researchers have argued that the role of external validity is invariant across
research traditions (ie experimental vs observational research) Defend the
perspective that the role external validity is invariant across these two research
traditions In addition present the weaknesses of this perspective
J11 In designing a research study researchers must consider trade-offs between internal and
external validity Explain what is meant by internal validity and external validity What
is the nature of these trade-offs How would you evaluatedetermine which is more
important internal or external validity for a particular study Why is this such an
important issue in organizational studies
J12 A researcher conducted a quasi-experiment to test the effects of participative decision
making (PDM) on job attitudes of employees Employees from different departments in
a large organization were assigned to either a treatment group (PDM implemented) or a
control group (no PDM) Random assignment was not possible because of work
schedules coordination of tasks etc Thus the design can be considered an untreated
control group design with pretest and posttest and is represented as follows (where
O=observation X = treatment)
________________
O1 X O2
-------------------------
O1 O2
_________________
The results of the experiment are presented in the graph below [no graph provided]
The dependent variable is job satisfaction and is measured on a 100 point scale (with
100 being extremely satisfied) How amenable are these results to causal interpretation
What is (are) the major threat(s) to internal validity B if any B for this type of design
given these results What steps can be taken to assess the extent of this (these)
threat(s)
K) Data Collection Methods
14) Describe the various methods of data collection (eg survey interview observation etc)
available to a social scientist What are the advantages and disadvantages of each relative to
each other
K1 Within micro organizational research much criticism has been raised concerning
the reliance on self-report survey data What potential problems does self-report
survey research raise How big of a problem do you think this is
K2 There are a number of methods for collecting data (eg survey interview archival
etc) that are available to a social scientistorganizational researcher Discuss each in
terms of their strengths and weaknesses both on their own and in comparison to one
another
K3 Pick an important construct in your favorite area of management research for which
there is some controversy about how it should be measured or operationalized (eg
environmental munificence or growth need strength) Give the prevailing verbal
definition of the construct and analyze the measurement controversy from two
broad angles First discuss how the controversy may or may not stem from claims
about how one measure is better or worse than another because it (or the other) is an
(a) archival record (b) direct observation (c) social report or (d) self-report That is
what are the relative strengths and weaknesses of each of these types of
measurement for the construct youre discussing Second discuss the construct
validity of the most commonly used measure(s) of this construct To answer this
second part you need to discuss just what construct validity is and how it can or
cannot be demonstrated In the situation you describe what could be done to
demonstrate or improve the construct validity of existing measures
K4 Interviewing in some form has been the workhorse for data collection in a variety
of research traditions positivistquantitative ethnographic feministpost-modernist
and increasingly historical research While each tradition elicits information from
respondents the goals and processes involved in interviewing vary considerably
across research traditions Discuss the purposes of the interview the relationship
between data and theory the roles assumed by the interviewer and the respondent
and the relevant criteria for assessing the validity and reliability of the information
obtained In addition compare and contrast the use of the interview as a data
collection method in the positivistquantitative tradition with its use in one of the
alternative traditions
L) Common Method Variance
L1 Many of us have had concerns about the reviews of our survey research which
suggest that data analyses of surveys are biased because of common method
variance effects of individual differences such as negative mood negative
affectivity and social desirability and the reliability and validity of the constructs
we are attempting to measure Define how these problems affect a research issue in
organizational behavior and the steps that might be taken to minimize such potential
criticisms of papers based on analyses of self-reported data through survey
instruments
L2 In a series of papers by Spector (1994) Schmitt (1994) and Howard (1994)
published in the Journal of Organizational Behavior arguments were provided for
and against the use of self-report questionnaire measures One of the issues
discussed that could limit conclusions drawn from relationships observed using self-
report measures was method variance What is meant by method variance what are
its sources and what impact is it expected to have on research findings
M) Sampling
M1 The manufacturing census samples all plants of 250 employees or more For
plants of 5-249 employees it takes a size proportional sample Plants of 1-4
employees are not sampled What challenges does this sampling method provide
to researchers What could you do to account for these problems if you were
TH
studying organizational (not plant) growth
M2 New York State has approximately 250000 employees in over 70 state agencies
commissions and boards ranging in size from approximately 50 to over 5000
employees Assume that you wanted to draw a representative sample of 1000
employees Describe two ways that you could draw such a sample and briefly
describe the advantages and disadvantages of each of these sampling approaches
IC
M3 The director of a national non-profit agency with approximately 10000
employees located primarily in regional offices in each of the 50 states the
United States has approached you and asked you to develop a study
(organizational survey) of organizational culture within the agency The agency
is about to embark on a variety of change initiatives including developing team
structures and the study is meant to examine various elements of organizational
culture that are potential barriers to change The director has indicated that he
would like to have the data analyzed at both the individual and office level of
analysis Because of funding limitations the agency will only be able to send the
survey to 1000 employees The director has indicated that there are three ways
of sorting employees all employees listed alphabetically all employees listed
alphabetically by state and all employees listed alphabetically by region (there
are between five and ten regions per state) Given these three ways of sorting
employees describe at least three different sampling approaches and the
advantages and disadvantages of each
M4 In your role as Teacher of Organizational Studies you are asked to prepare a
tutorial for beginning doctoral students on sampling design Assume that this
tutorial is part of a basic class in research design and that students in this class
have had a basic statistics course up to and including multiple regression Your
tutorial should focus on briefly defining and explaining the differences between
probability and non-probability samples You should make sure to present and
describe several types of probability samples (eg random systematic
stratified etc) and non-probability samples (eg convenience snow-ball quota
etc) and discuss general principles for when to use a probability vs a non-
probability sampling design For each sampling design you should also provide
at least one clear example of a situation where this type of sampling design is
appropriate
N) Cross-Cultural Research
N1 Discuss the problems in conducting cross-culturalnational comparison in terms
of (1) conceptualization and (2) research design and data collection
Define the three levels of measurement invariance How would the problems that
you have identified in part (a) affect measurement invariance How would you
examine measurement invariance by confirmatory factor analysis
TH
N2 Explain why using national boundaries as independent variable in cross-cultural
studies may not be appropriate in terms of theory and research methods What
alternative ways would you recommend
IC
O) General
O1 In your readings research has been described as choices among conflicting goals
(desiderata) For instance when choosing among research strategies a researcher
must choose among the desiderata of precision realism and generalizability The
trade-offs among desiderata occur for all aspects of research that is for the selection
of theories the treatment of independent variables research strategies the selection
of the problem to study rules of evidence for determining the meaningfulness of a
research finding and even the frameworks that describe the research process
Discuss what you see as the major trade-offs for each of the following aspects of
research That is discuss what you see as the major strengths and weaknesses
(advantages and disadvantages) of each aspect
a The trade-offs between internal and external validity
b The manipulation of the independent variable vs the observation of the
independent variable
c Basic vs applied research
3 DESIGNING A RESEARCH STUDY
A) General (Research Design)
3) Why is control so important in research design What are the different ways it can be
achieved (give a brief description of each control method) What are advantages and
disadvantages of each
A1 It has become almost a truism to note that the choice of methods influences theory
and questions data and conclusions (the causal direction might also be reversed)
Briefly discuss how the methods used have influenced research in any two of the
following areas leadership power and politics organization culture organization
justice Compare and contrast as possible Suggest some potentially fruitful
methodological directions for future work in these same topical areas and dont be
shy about reflecting on broader issues of how the field of organizational behavior
constructs its realities Lastly tie your discussion and reflections back to your own
future as a researcher what lessons or guidance do you derive from your
understanding of these issues
A2 Characterize as fully as possible what you see to be the methodological approach or
approaches in strategic management research Is there a dominant method or a wide
variety Discuss the reasons for the situation What are the advantages benefits etc
of the approach(es) in use What assumptions (ontological epistemological
ideological) do they embody Are current efforts ideal or at least adequate Are
there other approaches that could be useful If so how might researchers be
encouraged to use these as well If you see no advantage to more variety in
methodological approach support that point of view
A3 Describe a research question or area of interest to you and why you think it is not
only of interest but significance Using your understanding of research methodology
describe two ways of pursing the question that are as divergent on as many
dimensions as you can imagine Describe the advantages and disadvantages of each
approach How strong a link or fit is there between a research question and a
method
A4 In his 1957 article entitled The two disciplines of scientific psychology Cronbach
discussed the assumptions goals and methods used in experimental methods and
correlational methods in psychology
a According to Cronbach what is the main difference between the two disciplines
b Discuss the strength and weaknesses of each discipline
c What if anything could be done to improve the situation
B) Designing a Research Study
B1 Cook and Campbell describe the experiment as the research design with the
greatest methodological rigor However given the constraints present in most
organizations I-O Psychologists cannot often conduct experiments in applied
settings and must settle for techniques with less control than experiments
Describe a study to investigate the relationship between participation in a
supervisor training program and work performance which could realistically be
conducted in an organization If an experiment is not possible describe how you
would go about maximizing your ability to draw valid conclusions from your
design
B2 The XYZ Co has recently developed a sexual harassment web-based training
program The developers claim the program will cut training time and costs and
will be as effective or more effective than classroom-based sessions They
believe that this will be due to the increased availability of the program and the
ability for participants to review program material on demand Before the XYZ
Co developers launch this product they want you to determine if their claims
have merit Explain how you would design a study for this purpose
B3 Research suggests that demographic diversity improves group creativity but
reduces group efficiency Some argue that demographic diversity is just a proxy
for value and experience diversity and that demographic diversity on its own is
meaningless Design a test to settle this argument
TH
B4 E-mail has become a common form of communication in organizations and is
used for both formal and informal communication Because it has become so
IC
popular some people complain that the frequent use of e-mail leads to
miscommunication because they receive communications in e-mail that should
be accomplished through face-to-face or telephone conversations where there is
an opportunity for interaction You are interested in looking at this
phenomenon You are most interested in describing how e-mail is used for both
formal and informal communication and in examining the effect of the e-mail
use on organizational communication effectiveness Design empirical research
to address those issues
Describe your study in detail thoroughly explaining the research design
sampling plan data collection procedures ethical issues and proposed data
analysis for your research design Be sure to discuss the internal and external
validity of your research Which validity threats are ruled out and which
remain
REMEMBER Be thorough Your research design should demonstrate that you
are a competent researcher who is knowledgeable about the proposed research
methodology or methodologies Therefore be sure that you carefully describe
and give technical explanations for each component of your research
B5 Choose a specific situation involving employee selection eg artists for an
advertising agency (a) What strategy would you use in selecting the selection
measures (b) How would you combine the measures eg which measures
would you combine in a compensatory manner and which is a noncompensatory
manner (c) How would you assume test fairness defining various measures of
the term (d) How would you make final selections (e) How would you
validate your procedure (f) What considerations would enter in if your
company were too small to provide validation data (g) What difference would
it make if you were developing a procedure for deciding whether trainees
should be promoted as opposed to making new hires Please note--emphasize
but do not limit yourself to statistical issues
B6 There is evidence in the marketing literature of a non-monotonic relationship
between the expectations that customers have for retail service and their
eventual level of satisfaction with that service That is as a customers
expectations for service increase so does their eventual service satisfaction --
up to a point After that point the greater the expectations the lower the
eventual satisfaction Develop a hypothesis that includes a moderator variable
that might account for this evidence Give some reasonable rationale for it State
your hypothesis verbally as an equation as a directed graph (circle amp arrow
diagram) and as an X-Y function chart Discuss how it would or would not be
possible or useful to test your hypothesis via a laboratory experiment In your
discussion cover how and why a researcher could (not) manipulate the
independent constructs involved (mode X) whether or not random assignment
to conditions (mode R) is possible (including how may conditions would be
necessary) which alternative constructs could or could not be controlled (mode
K) and which constructs should be measured (mode Y)
B7 Assume you are the chairperson of a committee that must evaluate
undergraduate programs at your university Your task as chairperson is to
devise an approach (a design a research strategy a set of measures) that will
allow you to evaluate undergraduate programs Make sure that your approach
can be used in the future and at other comparable universities When developing
your plan be sure to address at least the following issues
a the type of design you would select Compare and contrast the selected design
with another possible design
b the type of research strategy you would select Compare and contrast with
another possible strategies
c discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
B8 Assume you are an organizational research design expert assigned to the
Strategic Planning Department of a large multi-national manufacturing firm
The Department has developed a new PC-based software package called
STRATPACK The software (and a one-week training course to learn how to
use it) is intended to improve the long-range planning ability of middle and
upper-level managers
Your job as research design expert is to devise research (a design a research
strategy a set of measures) that will allow you to evaluate the effectiveness of
the STRATPACK program Describe a research design for evaluating the
program Make sure that your research approach can be used in the future and at
all sites in the company When developing your plan be sure to address at least
the following issues
a discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
b the type of design you would select (eg a design where you manipulate the
independent variable versus observe the independent variable) Compare and
contrast the selected design with another possible design
c how your design deals with the major forms of validity Be sure to examine at
least internal external and construct validity
B9 Assume you are a consultant hired to evaluate the effectiveness of an industrial
safety program undertaken by a large manufacturing organization The safety
program is a behavioral one that provides rewards such as monetary bonuses or
extra paid vacation days for safety behaviors in terms of accident-free days
weeks etc Your task is to devise an approach (a research strategy a design a
set of measures and a general analysis strategy) that will allow you to evaluate
the safety program Because of the potential for the influence of many
extraneous variables on any safety program it is difficult to design research a
single cross-sectional study than can evaluate the impact of a single safety
program How would you design a study to evaluate the impact of the safety
program When developing your plan be sure to address at least the following
issues
a the type of research strategy you would select Compare and contrast with
another possible strategies
b the type of design you would select Compare and contrast the selected design
with another possible design
c discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
B10 One of the most important areas of research is forecasting of human resources
needs based on strategic positions of organizations For example NY State must
carefully forecast its human resources needs as it proceeds with significant lay-
offs of state employees Future human resources needs are generally evaluated
by either statistical ie regression or simulation or clinical judgment i e
supervisors judgments methods
a Design a single study that addresses the empirical question of whether
statistical or judgmental methods are better for forecasting human resources
needs You may discuss a program of research but please be quite specific in
your description of the first study
b What are the critical methodological issues in doing this kind of research
c What are the critical applied (or practical) issues in doing this research
d Are the issues in b and c related
B11 In the past decade computinginformation technology has changed many
aspects of organizational life For example the technology can make increased
decentralization possible by improving communication between central offices
and field offices Computer networks and word processors can enhance group
empowerment by making it possible for team members to create and edit
written group products quickly even if the individuals are at different locations
Some have argued that computinginformation technology will foster the
paperless productive office nevertheless others argue that the technology only
increases paper and reduces office productivity You are applying to the
National Science Foundation for a grant to conduct research that examines the
impact of computing information technology on organizational decision
processes The NSF application procedure imposes five basic requirements that
your research design must fulfill in order to receive funding Note A very
significant factor affecting NSF grant decisions is a clear demonstration that the
researcher is knowledgeable about the research methodology used Write your
response to each of the following five grant requirements Be sure not only to
respond to the requirement but also to demonstrate your research
competence
1You must design a study that uses two different methods
(interviewobservation survey experiment or quasi-experiment) Describe your
two methods in detail and provide a rationale for the key elements (eg
sampling data collection proposed analysis) of your methods Be sure to
discuss and evaluate the internal and external validity of both methods
2 As part of your research design you must select a conceptual (latent) variable
central to your proposal (use centralization of decision making as your
variable) and describe how you will develop your own measure (You may not
simply use off the shelf instruments)
3 You must describe how you will test for the reliability of the measure
(centralization of decision making) you developed in step 2 The NSF insists
that you describe how you will evaluate both the temporal stability and the
internal consistency of your measure Be sure to discuss what temporal stability
and internal reliability mean and how they are related
4You must describe how you will assess the validity of the measure
(centralization of decision making) you developed in step 2
5 NSF requires a brief statement and defense of the philosophy of science
underlying your research Discuss your position and show how your research
design is consistent with your philosophy
B12 Many organizations in the United States economy have installed some form of
Empowered Teams as an alternative or supplement to traditional bureaucratic
structure Preliminary evidence of the effectiveness of empowered teams
however is mixed--some organizations have claimed success and others have
reported failures The evidence however is predominantly anecdotal--written
for trade magazines by the organizations themselves There are few rigorous
empirical studies assessing the effectiveness of empowered or self-managed
teams You are applying to the United States Department of Labor (USDOL) for
a grant to conduct research that examines the effectiveness of empowered
teams The application procedure of the USDOL imposes three requirements
that your research design must fulfill in order to receive funding Write your
response to each of the three grant requirements The importance of each section
is implied by the evaluation points allocated by the USDOL to each of the three
requirements given in parentheses
1 (50 points) Your study design for assessing Empowered Team effectiveness
must use two different methods (interview observation archival analysis
survey simulation experiment or quasi-experiment) Describe in detail and
thoroughly explain the sampling plan instrumentation data collection
procedures and proposed data analyses for both methods Be sure to discuss the
internal and external validity of both methods and how the two methods
complement one another
2 (30 points) As part of your research design you must select one conceptual
(latent) variable central to your proposal and describe how you will develop
your own operationalization of the measure (You may not simply use off the
shelf instruments) Use the concept of group morale to demonstrate your
operationalization methodology Be sure to explain very explicitly to the
USDOL how you will assess the validity and reliability of the group morale
measure you are developing
3 (20 points) The USDOL traditionally has funded research conducted only
within the general paradigm of logical positivism but now is more open to other
research paradigms as well Your grant proposal must provide a statement and
defense of the explicit philosophy of science underlying your research Describe
your philosophy of science and show how your research design is consistent
with your philosophy
REMEMBER Be thorough You not only must design effective research but
you also must demonstrate to the USDOL that you are a competent researcher
It is absolutely vital to the USDOL that the principal researcher is
knowledgeable about the proposed research methodologies Therefore be sure
that you always carefully describe and give technical explanations for each
component of your research design and explain all technical terms (eg
Cronbach alpha KR-20 Likert scale)
B13 Assume that you are working as part of a research team that is responding to a
RFP (Request for Proposals) from a funding agency for research on work
socialization and newcomer adjustment The RFP calls for rigorous field
research that tests the effectiveness of theory-based interventions aimed at
facilitating the adjustment of new organizational members to complex andor
stressful work conditions The major goal of your teams research is to test the
effectiveness of a self-regulation intervention which trains newcomers to
identify and use relevant social information and cues to regulate work behavior
Your group hypothesizes that self-regulation training will be more effective
than other common treatments or interventions (eg realistic job previews
institutionalized socialization tactics)
You have been included in the team because of your methodological expertise
Your role is to design a rigorous field experiment or quasi-experiment to test he
effectiveness of the self-regulation training program REMEMBER THE
MAJOR CRITERION FOR FUNDING IS THE RIGOR OF THE RESEARCH
DESIGN Design a field study to include in the grant proposal Your proposal
should contain the following two sections
1 Study Design Construct and describe in detail an experimental or quasi-
experimental design to test the effectiveness of your intervention Describe in
detail the experimental groups (including how they will be constructed) the
research setting the sampling plan for study participants the treatment
manipulation and the data collection procedures Also indicate any control or
nuisance variables that may be measured
After describing the procedures write a justification of the design What threats
to validity does it rule out or limit and what threats to validity remain
II Measurement Describe the steps you would take to achieve valid and
reliable measure of the latent (conceptual) variable worker adjustment Your
team feels that as part of the proposal you must develop an original
operationalization of adjustment (thus you cannot simply use existing off the
shelf measures) Indicate in adequate detail how you would operationalize the
measure and indicate how you would demonstrate reliability and validity
B14 In describing their notion of the collective mind Karl E Weick and Karlene H
Roberts note Our focus is at once on individuals and the collective since only
individuals can contribute to a collective mind but a collective mind is distinct
from an individual because it inheres in the pattern of interrelated activities
among many people (p 360) Collective mind is not indexed by within-group
similarity of attitudes ideas or activities A collective mind is one in which
many people or many groups integrate their different attitudes ideas and
activities heedfully As Weick and Roberts note People act heedfully when
they act more or less carefully critically consistently purposefully attentively
studiously vigilantly conscientiously pertinaciously (p 361)
The idea of the collective mind as heedful interrelating is developed in the
following excerpt When people make efforts to interrelate these efforts can
range from heedful to heedless The more heed reflected in a pattern of
interrelations the more developed the collective mind and the greater the
capability to comprehend unexpected events that evolve rapidly in unexpected
ways When we say that a collective mind comprehends unexpected events we
mean that heedful interrelating connects sufficient know-how to meet situational
demands For organizations concerned with reliability those developments
often consist of unexpected non-sequential interaction (p366)
An example of heedful interrelating occurs as a pilot lands herhis aircraft on the
deck of an aircraft carrier The pilot does not actually land She is recovered
A recovery is an interrelated set of activities among air traffic controllers
landing signal officers the control tower navigators deck hands the helmsman
driving the ship etc These activities can be interrelated more or less heedfully
depending on the care with which the different units contribute represent the
situation and subordinate their activities to the single purpose of successful
recovery (p 363)
You are to design a two-part study
Part I You are to design a measurement study which assesses heedful
interrelating (ie collective mind) with a quantitative measure in a replication
of an aircraft carrier flight deck or other situation of your choosing Describe
your research strategies including operationalization of the variable selection of
the sample subjects data collection data analysis and so on for the purpose of
developing a measure of heedful interrelating
Part II Using the measurement tool developed in Part I and any other tools as
needed describe how you would design a study which would compare heedful
interrelating across organizations Choose at least one macro-organizational
variable (eg technology environment) as your basis of comparison Here you
must describe how you would make your selection of organizations to be
compared your data collection procedure data analysis and so on
B15 Many organizations in the United States have installed cross-functional teams to
counteract the silo mentality of traditional bureaucratic structure Preliminary
evidence of the effectiveness of cross-functional teams however is mixed --
some organizations have claimed success and others have reported failures The
evidence moreover is predominantly anecdotal--written for trade magazines by
the organizations themselves Since there have been few rigorous empirical
field studies assessing the effectiveness of cross functional teams the National
Science Foundation has decided to fund research on the topic
Assume that you are submitting a research proposal to NSF for a grant to
research the effectiveness of cross-functional teams Describe in detail and
thoroughly explain the research design sampling plan data collection
procedures ethical issues and proposed data analysis for your research design
Be sure to discuss the internal and external validity of your research Which
validity threats are ruled out and which remain NSF also requires that you
provide a statement and defense of the explicit philosophy of science underlying
your research Describe your philosophy of science and discuss how your
research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but
you must also demonstrate to NSF that you are a competent researcher It is
absolutely vital to NSF that the principal researcher (you) is knowledgeable
about the proposed research methodologies Therefore be sure that you always
carefully describe and give technical explanations for each component of your
research design and explain all technical terms (eg Cronbach alpha KR-20
Likert scale)
B16 Assume that you are submitting a research proposal to the Department of
Commerce (DoC) for a grant to research the effectiveness of virtual work teams
A virtual work team is a leaderless collection of individuals who are
geographically separate from one another and share their expertise using
internet media such as a listserver or Lotus notes The DoC requires that the
researcher use both qualitative and quantitative methods to gather data Describe
in detail and thoroughly explain the research design sampling plan data
collection procedures ethical issues and proposed data analysis for your
research design Be sure to discuss the internal and external validity of your
research Which validity threats are ruled out and which remain The DoC also
requires that you provide a statement and defense of the explicit philosophy of
science underlying your research Describe your philosophy of science and
discuss how your research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but
you must also demonstrate to DoC that you are a competent researcher It is
absolutely vital to DoC that the principal investigator (you) is knowledgeable
about the proposed research methodologies Therefore be sure that you always
carefully describe and give technical explanations for each component of your
research

5 MEASUREMENT
A) Measurement Terms
A1 There are four levels of measurement rigor in management research Discuss each
one What properties do measurements at each level have (ie how much
information do the numbers from each level of measurement convey) How can the
numbers be changed (transformed) and still retain the properties of their
measurement level Pick one construct from a favorite research domain and give an
example of an operationalization of that construct at each of the four levels of
measurement rigor (provide arguments about why you think those examples reflect
each level) Lastly treat each examplelevel as a dependent variable in some
statistical analysis Given an example of a statistical technique appropriate for
analyzing data at that level of measurement rigor
A2 Define (and discuss important features or issues concerning) the following
constructs measurement (Define any six terms)
1 Construct validity 6 Item analysis
2 Likert scaling 7 Semantic differential
3 Cronbachs alpha 8 True score
4 Unobtrusive (trace) measurement 9 Generalizability theory
5 Interval scale 10 Criterion-related validity
11 Sociometric choice measures
B) Operationalization
B1 a) You are conducting a study which requires you to measure Hong Kong real
estate agents self-assessment of performance Since there is no existing
measurement available you have to develop the instrument by yourself
Describe how you would develop the measurement assuming that you have no
idea of how many dimension the construct has
b) Suppose you have developed an instrument consists of 20 questions
measuring 4 dimensions (5 items per dimension) from (a) You collected data
from another 300 real estate agents to validate your instrument Explain how
TH
you would use structural equations model (SEM) to examine the reliability and
validity of the instrument What are other concerns about reliability and validity
that are not addressed by this approach
B2 The research and business world have been fascinated with the concept of
organizational culture However operationalizing this construct has been a
difficult task Discuss the ways in which the construct has been operationalized
(eg technique static v dynamic sample selection generalizability) Critically
analyze each of these methodologies Then choose a methodology you would
use to examine organizational culture and defend your choice Describe how
you would study culture and what more would be known about culture as a
result of your study
B3 Suppose you are setting out to develop a new measure of a construct You want
this measure to be used in survey research and you want to establish its validity
and reliability Your goal is to have at the end of the process a measure that is
defensible and likely to be widely accepted by other researchers studying that
construct What steps would you take to conduct such a program of research
For each step explain the purpose of that step explain why that step is
important explain what methods and statistical procedures you would employ at
each step and explain what evidence you would hope to gather at each step
B4 Assume you are interested in constructing a new measure of (fill in with a
relevant variable from your field) Detail the major concerns that need to be
addressed and the steps that need to be taken in working toward validating this
new measure
B5 Assume that you recently read an article on workplace violence which you
found very interesting The authors argued that one of the predictors of
workplace violence was a construct called propensity to be violent and used a
one-item measure as follows How likely are you to become violent when
provoked You had serious doubts about the authors measure and decided to
develop your own
(a) How would you go about developing items to measure propensity to be
violent
(b) How would you determine whether the instrument was reliable
How would you determine whether the instrument was valid
B6 A concern in organizations is retirement of baby boomers within the next 5 -
10 years This concern is focused on the loss of older employees with skills
critical to the core business functions of organizations In order to continue to
have employees with those critical skills it seems necessary to retrain some
older workers However past practice in most organizations has been not to
retrain older workers for a variety of reasons mostly financial A researcher
working for the Human Resources Department of a large corporation - 13500
employees in 12 different plant locations - hypothesizes that the major reason
for not retraining older workers is ingrained in the culture of the corporation
IC
The researcher feels that older workers are not as highly valued as younger
workers in terms of their potential usefulness after retraining The researcher
searched the literature but found nothing in the existing literature to measure
the cultural value construct What should the researcher do to establish a reliable
and valid self-administered paper and pencil measure of this construct namely
the value of retraining older workers

of the concept of technological complexity What standards would you use to
determine if your operationalization is valid
B8 Organizational researchers have several strategies available to them for
gathering information (eg self-report measures archival measures direct
observation and trace measures) Assume that you are going to conduct
empirical research to assess the role that the structure of the organization plays
in determining the level of organizational effectiveness Briefly review the
strengths and weaknesses of the basic strategies (that is self-report measures
archival measures direct observation and trace measures) for measuring
organizational effectiveness Next describe and justify the steps you would
take to develop an operationalization of the concept of organizational
effectiveness What standards and procedures would you use to determine if
your operationalization is valid
B9 One of the most important topics of recent research has been stress in the work
place One of the most important problems with understanding this literature is
the varying definitions and measurement of this construct Suppose you had
decided to investigate the relationship between stress at the work place and dual
career family happiness

Further assume that you have used previous literature and your own conceptual
development to delineate 2 dimensions of X specifically XF1 and XF2
Describe the steps you would go through in developing testing and evaluating
this new scale With regard to testing and evaluating be sure to consider the
role of factor analysis (both exploratory and confirmatory) and item analysis
Also you will want to make sure that your new multidimensional scale shows
evidence of validity (several kinds) and reliability so be sure to examine these
issues and explain how specific information gathered from the above testing

these methods map up with the definition of reliability What is the impact of the
number of test items and sample size on Chronbachs alpha and why would this
effect occur or not occur (Note Do NOT discuss inter-rater reliability)
C10 Schmidt and Hunter (1996) described several types of measures typically used in
organizational research and identified the type(s) of measurement error affecting
each of them in various situations For each measure below indicate the types of
error and sources of error that are most likely to affect it Then indicate what
could be done to reduce errors of measurement andor what can be done to
control for errors statistically

worker)
d Aptitude tests taken as part of the hiring process
C11 Suppose you had conducted research on the relationship between organizational
commitment and rigidity of organizational structure in 200 firms Your measure
of rigidity was based on number of organizational authority levels and the degree
to which written organizational rules existed and defined role behaviors for
employees Thus an organization with a large number of organizational levels
and specific written policies defining appropriate role behaviors for employees
would score high on rigidity of organizational structure After analyzing your
data you find that there is a statistically significant negative correlation between
commitment and rigidity which is consistent with your hypothesis However the
reliabilities for your two measures are
(1) commitment = 23 (2) rigidity = 83
How should you interpret your results What could you do to fix this situation
Describe the specific steps (in order) you would follow to develop a more
reliable measure of commitment

research literature This type of research raises many issues and presents many
challenges in terms of designing the research measuring variables and collecting
and analyzing the data Assume that you are interested in aggregating data (eg
from the individual to the group or from the firm to the industry) for one or more
variables What are the major issues you will need to deal with
D3 A researcher wants to measure organizational climate for continuous learning
Organizational climate is operationalized as a shared consensual aspect of the
organization -- the shared perception among employees that the organization values
and supports continuous learning Describe how you would measure organizational
climate in this case Specify (a) the level (ie individual group organization) at
which the construct exists (b) the level at which you would measure the construct
and (c) the procedures that you would use to establish that measurement is aligned
with theory (ie the construct validity of the measure)
E) General (Measurement)
E1 Studies in organizational behavior research often rely on single-item measures of
key constructs The use of single-item measures has long been criticized based
on the premise that single-item measures are unreliable However Wanous
(Wanous amp Hudy 2001 Wanous amp Reichers 1996 Wanous Reichers amp Hudy
1997) has recently argued that single-item measures can exhibit adequate
reliability Wanous based this conclusion on a procedure for estimating the
reliability of single-item measures using the classic formula for correction for
attenuation Subsequent studies have yielded mixed results regarding the
conclusions of Wanous (eg Loo amp Kells 1998 Nagy 2002) and the veracity
of the perspective advocated by Wanous remains in question Summarize and
assess the arguments for and against the use of single-item measures and
evaluate the procedure and evidence offered by Wanous regarding the reliability
of single-item measures Based on your assessment and evaluation develop
recommendations regarding the use of single-item measures in organizational
behavior research

E2 Ipsative measures have become prevalent in organizational behavior research
Ipsative measures ask respondents to answer questions relative to one another
such that the scores for all questions sum to the same constant for all respondents
Examples of ipsative measures include rankings Q-sorts and the allocation of a
fixed number of points (eg 100) across a set of response options Ipsative
measures may be contrasted with absolute measures which ask respondents to
answer questions independently from one another Absolute measures are
exemplified by rating scales using an interval or ratio numeric response format
The relative merits of ipsative and absolute measures have been debated for
decades (eg Cornwell amp Dunlap 1994 Hicks 1970 Johnson Wood amp
Blinkhorn 1988 Saville amp Wilson 1991 1992) yet the fundamental issues
underlying this debate have not been adequately addressed in organizational
behavior research For example measures of organizational culture and values
are often ipsative and some researchers advocate these measures over absolute
measures (eg Meglino amp Ravlin 1987 OReilly Chatman amp Caldwell 1991
Ravlin amp Meglino 1987 see also Rokeach amp Ball-Rokeach 1989) Review the
relative merits of absolute and ipsative measures Based on your review which
form of measurement is most appropriate and why Do your conclusions depend
on the construct being measured If so what types of constructs are best suited to
ipsative measures and what types are best suited to absolute measures Next
apply your conclusions to the measurement of culture and values in
organizations What specific arguments have been advanced in favor of ipsative
measures of culture and values How sound are these arguments Should ipsative
measures be used in the study of organizational culture and values If not how
can absolute measures of culture and values be developed that address the
concerns voiced by advocates of ipsative measures Provide a specific example
of the type of measure you would propose

facets of a concept Although such measures are prevalent and in some cases are

E5 Suppose Roberta Von Eisenbrick is a researcher interested in the consequences of
AFFECTIVE CONFLICT (AC) in decision-making teams She gets access to a
variety of outcomes assessment committees at each of 87 different schools in
the Dallas Independent School District and gains permission to tape-record two
of their meetings (one in February and one in March) Such committees have
been formed to develop quantitative ways to track pursuit of school goals and
provide accountability to local and state governments These are often divisive
teams with heated meetings because what gets assessed is what usually gets
rewarded After both of these meetings the committee members each
fill out a short questionnaire that contains 20 Likert-type items measuring how
much AC occurred (eg People in our group often get angry with each other)
The individual scores are summed across items then averaged across team
members to come up with a group-level AC score for each of the 87 2
meetings The same procedures are followed for a 5-item measure of Group
Cohesiveness (GC) which is predicted to be reduced by higher levels of AC
Roberta also listens to every tape and from her expert judgment she rates each
groups meetings on the same 20 items Those 20 ratings are summed for each of
the 87 2 meetings Now Roberta is interested in evaluating her measure She
wants it to have excellent psychometric properties including reliability and
construct validity

D) ModeratorsMediators
D1 Moderation and mediation provide different ways to model third variable effects
(a) Please define both of these terms (b) Sketch a conceptual model to show how
each relates to main effects (c) Using variables of your choice please write
hypotheses to reflect both (d) Explain how each is tested analytically
D2 Discuss moderators and mediators Provide an example of how (1) a moderating
variable influences the relationship between the independent and dependent
variable and how (2) a mediating variable influences the relationship between
the independent and dependent variable Describe how you would test for both
moderation and mediation using regression
D3 Many theories in organizational research predict that the effects of one variable
on another are moderated by a third variable Such moderator effects are
typically tested by entering the product of two variables as a predictor after
controlling for the two variables that constitute the product Several researchers
have pointed out that this product is often highly correlated with the squares of
the two constituent variables and have suggested that moderating effects may be
tested after controlling not only for the two constituent variables but also their
squares (eg Cortina 1993 Ganzach 1998 Lubinski amp Humphreys 1990
MacCallum amp Mar 1995) Discuss the strengths and weaknesses of this
approach as compared to methods that use only the product term and its
constituent variables Conclude with recommendations as to when and under
what conditions organizational researchers should test moderator effects with the
squares of the constituent variables in the equation

D4 Assume you are interested in studying relationships amongst three variables X
Y and Z Your first hypothesis posits Z as a mediator of the relationship between
X and Y Your second hypothesis posits Z as a moderator of the relationship
between X and Y Draw the figures depicting each of these hypothesized
relationships and describe (make sure to write regression equations) how you
would test each of these hypotheses
D5 The amount of time and effort that the average person pours into his or her job
has risen steadily over the last two decades such that the average person now is
working one more week per year than the average person in the mid 1970s This
steady increase has fueled research interest in the construct of Job Burnout (JB)
which is an emotional and physical exhaustion associated with ones work
Organizational Stress (OS) the perception of greater demands than available
resources in ones work environment is thought to be one of the chief
antecedents of JB However time spent under OS is thought to make its affects
on JB accumulate or worsen Work Role Withdrawal (WRW) the avoidance of
responsibilities or the deliberate reduction of inputs to ones job is believed to be
the chief consequence of JB
a Formally state these ideas as verbal hypotheses as equations and as a complex
directed graph (circle amp arrow diagram)
b Conceptually what is a mediator Define the term and identify the mediator in
your hypotheses in (a) What elements or steps in a study design (not statistics)
that would be helpful for detecting the mediating relationship that was proposed

subdomains of management Further demonstrate your understanding of
moderator variables by picking which variable in (a) is the moderator Show the
moderating relationship in an X-Y (or multi-layered) chart Again what elements
or steps in a study design (not statistics) would be helpful for detecting the
moderating effect implied above

student about the appropriate use of multiple comparisons and post hoc tests in
analysis of variance Your student colleague already has been introduced to ANOVA

for differences among the different levels or cells of a categorical variable In your
description you should discuss among other things
a the statistical and philosophical issues raised by post hoc analysis and data
snooping

recommendations You conduct a well-designed controlled study (details are unimportant) and discover students who use the new book perform 10 better on a standardized subject
matter exam than those using the old book (p = 027) Both books are readily availabe their prices are almost identical and both are equally acceptable to the instructors What is your recommendation to the chair
F1 Attached is the beginning of an article Your task is to write the results section by
1 making up and reporting plausible descriptive statistics that will help the
reader understand the results of the statistical tests you report and the nature of your
sample (Hint this can be presented in the form of a table)
2 describing and defending your choice of appropriate statistical tests of the
hypotheses and the steps that you would go through in carrying out these tests
3 making up and reporting results of these tests that are consistent with your
descriptive statistics and with any information in the rest of the article about the
results found (Hint this can be presented in the form of a table)
4 describing how well these results provide support for the hypotheses You
may want to note any relevant threats to validity here
Be sure to state any assumptions you make
F2 Assume that the Personnel Manager of a local firm Ms B dFlandres hired you to
analyze some data that her assistants had collected over the past several years The
data consist of (a) job performance ratings that were made in June of 1990 and (b)
scores on 25 predictor variables (eg measures of education job experience job
tenure job aptitude personality) that were measured when the individuals were hired
(between April 1987 and May 1988) She had data from only the 110 subjects (60
males and 50 females) who were hired during the period and were still employed by
the firm One objective of your analysis (analyses) is to determine how well the
performance criterion can be predicted by the predictors What strategy would you
use in analyzing the data Describeexplain (b) Is sample size an issue for your
analyses Explain If it is what will you do to deal with problems stemming from
sample size Assume that no additional data can be collected at this time (c) Some
preliminary analyses that you do reveal that five of the predictor variables correlate
(zero-order basis) about 75 with one another Will this influence the analyses that
you use Will it influence the validity of conclusions derived from your proposed
analyses (d) Ms dFlandres is interested in knowing if the predictor variables are
equally effective in predicting the job success of males and females What analysis
or analyses would you do to deal with this issue
F3 Assume that you have been provided with data on 12 conceptually distinct variables
that are moderately correlated with one another at the empirical level The data are
from students in four different college majors ie astronomy (A) biology (B)
criminology (C) and demography (D) The 12 measured variables fall into the
general categories of mental health (tension emotional withdrawal hallucinations
guilt feelings blunted affect and suspiciousness) and job satisfaction (work itself
supervision co-workers pay promotion prospects and working conditions) Your
task is to determine if the individuals in the four college majors differ from one
another on the 12 measured variables
(a) What statistical technique(s) would you use to test for group differences
Explain Be specific about the procedures(s) that you would use
(b) What statistical estimate would you use to estimate the extent to which the
groups differ from one another Be specific
F4 The following statistical table published in a recent issue of Work amp Occupations
was taken from an article discussing variables influencing resistance and citizenship
behaviors in the workplace Resistance behaviors include playing dumb withholding
effort work avoidance subverting particular managers and sabotage Citizenship
behaviors include cooperation engaging in peer training use of insider knowledge to
facilitate production commitment to organizational goals giving extra effort freely
Both measures are global constructs aggregated to the interval level and
standardized
The table reports the results of a series of ordinary least squares regression equations
with standardized coefficients Explain the meaning of the statistics presented What
do these statistics tell us generally about the relationship between resistance
behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows
Anomie Index -standardized interval level measure tapping multiple dimensions
The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)
F5 Researchers collected data from a sample of 350 companies on the following
variables
size (measured as number of employees)
Business Strategy (a nominal variable with 2 response options low-cost provider or
differentiator)
HR Strategy (a nominal variable with 2 response categories High commitment or
low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

I2 A study examined the effects of gender and pre-training motivation on the transfer of
training in terms of improved performance for 123 new industrial managers The
training was on supervisory skills and the dependent variable was based on the
appraisal of the supervisors performance before the training and three months after
the training The performance appraisal data were collected for research purposes
only and resulted in a total transfer score from 1 to 25 with 1 being low Pre-training
motivation was based on a 12 item Likert scale with an alpha of 86 Two groups
were identified for the pre-training motivation variable - the bottom 13 (low) and the
top 13 (high) Table 1 contains the ANOVA results and Table 2 contains the cell

mirrors Explain both sides of the debate and then lay out the role of meta-analysis
as you see it within the time span of your career as an academic To do this use
examples of already written (or yet to be written) articles as models
J5 A frequent criticism of non-quantitative research summaries (literature reviews) is
that researchers do not carefully examine how particular research designs might have
affected the statistical outcomes of the studies included in the literature review Meta-
analysis however allows one to statistically examine such effects Assume you are
conducting a meta-analysis of the relationship between leader behaviors and group
productivity Briefly describe the steps you would take in conducting a meta-
analysis What aspects of the original research designs would you examine in your
meta-analysis What steps would you take in gathering and coding data to enhance
the credibility of your analysis

What is the role of theory in the two factor analyses
IC
O2 Compare and contrast Exploratory Factor Analysis (EFA) with Confirmatory TH

assumptions usage and limitations
O3 How do exploratory and confirmatory factor analysis differ What are the
advantages and disadvantages of each
O4 Describe the differences between exploratory factor analysis (EFA) and
confirmatory factor analysis (CFA) When would you use one verses another
Are there ways to use EFA in a confirmatory way Can you use CFA in an
exploratory way Also describe the difference in principal components analysis
(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression

information in each matrix and its purpose
(2) For what purpose do researchers use factor analysis Explain In the process
provide a very brief description of a study for which factor analysis would be a
useful data analytic technique
O7 Factor analysis is an important statistical technique in organizational research

c the type of quantitative output that results from applying the technique
d how a researcher would use the output in his or her research

f the important issues and problems in using the technique
P) Structural Equation Models
P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)
Please comment on these restrictions versus access argument Which side do you
take
What are the strengths of SEM Give some examples
What are the weaknesses of SEM Give some examples

also situations where one methodology or the other might be most appropriate
F) Laboratory vs Field Research
F1 Of the various research approaches available to organizational researchers
laboratory experiments are held up as an ideal because of their potential for high
internal validity On the other hand field research including participant observation
and field experiments have high potential for external validity Discuss specifically
the strengths and weaknesses of laboratory versus field experiments How would
positivist researchers think differently about these tradeoffs than would
phenomenologists

hypothesized relationship between two constructs an independent and a dependent
variable in a substantive area of your choice (eg Strategy OB HRM
Organizational Theory) provide a verbal mathematical and graphical statement of

survey methods in tandem
G) Experimental Design
2) A colleague suggests to you that only true experiments can provide useful results in
science Why might she say this What would you offer as a defense for the role of quasi-
experimental and non experimental designs in the context of the social science In
answering this question make sure you identify the defining characteristics of each design
type
9) Why and when should we be concerned about non response in research What are the
things we can do to try and decrease non response (or increase response rates)
11) Why might a researcher choose to utilize an experimental design that incorporates pretest
measure on the DV
G1 Experimental designs oftentimes come under attack due to perceived limitations in
external validity (a) Relative to other design types what strengths and weaknesses
do they offer (b) What experimental design structure is the strongest Why (c)
What is the relevance of research design for results and theory development
G2 Meta-analysts often investigate whether the quality of research design (eg
randomized experiments vs non-randomized designs) influences average effect
size In their meta-meta analysis of psychological educational and behavioral
treatments Lipsey and Wilson (1993) found that In a given treatment area poor
design or low methodological quality may result in a treatment estimate quite
discrepant from what a better quality design would yield but it is almost as likely
to be an underestimate as an overestimate (p1193) A few methodologists (eg
Shadish) have attempted to identify factors that may explain the relative magnitude
of effect sizes from randomized and nonrandomized experiments Please review
these findings and add your tentative model of the conditions under which random
experiments will produce larger smaller or equal effect sizes relative to
nonrandom designs Discuss possible implications for research design in the
context of real-world interventions
G3 Analysis of covariance and randomized blocks designs are sometimes referred to as
noise-blocking designs Explain what this means and give an example of (a) a
randomized blocks experiment and (b) an analysis of covariance experiment Keep
your examples simple Describe how such designs are noise-blocking when used
with randomized assignment of subjects to experimental condition and contrast
that with the role such designs serve in quasi-experimental designs
G4 Team performance in Bafko Industries varies considerably across teams and from
month to month The senior VP in charge of team development thought that a team
training program could improve the performance of these teams A consultant
convinced him that his firms training program which lasted only one week and
cost only $25000 per team) could raise the performance of Bafkos teams The VP
however wanted to experimentally test the efficacy of this training program before
he adopted it widely throughout the firm So the consultant suggested the following
experimental test
There were 48 teams in Bafko that showed significant variation from month to
month in their level of performance The consultant chose the 24 worst performing
teams based on last months data and assigned them to the training group After
all he argued these were the ones who most needed it The other teams were
assigned to the control group The training group received the training program
(lasting one week) at the beginning of the next month while the control group
teams did their normal routine Performance scores were gathered at the end of the
month The results showed that the training group teams had a significantly larger
rise (ie statistically significant) in their performance than did the control group
teams (who as a group did not improve at all) The consultant proudly displayed
these results and argued that they convincingly demonstrated the efficacy of his
program
How would you advise the VP Specifically what is the validity of the consultants
conclusions If you think he might be mistaken what specific threats to internal
validity are particularly plausible
G5 Consider the following design
N O Xa O
N O Xb O
N O Xc O
N O O where
Xa Xb and Xc represent different levels of a training program that varied in its
length across three different work groups In group a the training time was 40
hours in group b it was 30 hours and in state c it was 20 hours The training was
designed to instill customer service values in the team members O represents a
measure of customer service attitudes measured with a 20-item Likert scale This
measure was administered one week before the training program and 3 months
later The researcher hypothesized that the training program would improve
customer service attitudes and that longer training would have stronger effects
The design is a non-equivalent groups design because people were not randomly
assigned to groups even though groups were randomly assigned to treatment
condition Each group has a sample size of 36 members The reliability of the
customer service attitude scale was 78 at the pretest and 80 at the posttest The
pretest means were as follows
Group A 26
Group B 23
Group C 27
Control Group 25
a Construct a regression model that will test the researchers hypothesis Be
explicit here describing each variable in the model and what regression effect(s)
you would expect to find if the hypothesis were correct (Hint everything you need
to know is in Trochims chapter 11 and what we discussed in class) (10 points)
b Describe any serious threats to internal validity (10 points)
c Discuss how you might amend this design to improve its internal validity(10
points)
G6 Often in organizational research the researcher is faced with having only one group
on which to experiment and thus cannot use a control group when conducting
experiments This occurs for example in taxation experiments when you cannot
selectively apply new tax laws to different groups or when you wish to test the
efficacy of an incentive plan that must be applied to all members of a company In
such situations the researcher must be creative in assembling a quasi-experimental
design that has high validity (and usually the challenge concerns internal validity)
Consider the following scenario
A manager of a retail store wants to test the efficacy of an incentive program in
changing the selling behaviors of her retail sales clerks Specifically she wants to
test a behavioral reinforcement program in which sales peoples behavior is
recorded on in-store video cameras The tapes are analyzed each night and the
experimenter tabulates the frequency of various behaviors (eg offering assistance
to customers restocking items straightening up displays suggesting accessory
items to accompany the items that a customer is purchasing) The manager then
rewards the clerks with a monetary bonus based on the frequency of desired
behaviors She would like to conduct a valid experiment to see what effect such an
incentive program has on employee behavior but because of concerns about
employee morale she cannot assign clerks to treatment and control groups Instead
she has to apply the experimental treatment to everyone in the store She learned in
her research methods class (which the company requires all its managers to take)
that a single group experimental design typically has very low internal validity
Your job as a consultant is to help her design an experiment given her constraints
that would produce interpretable (ie internally valid) results Describe the details
of the design you would recommend using the notation in Trochim (2001) If the
design you come up with has a specific name use it As part of describing your
design discuss how the data would be analyzed and what particular effect you
would look for
G7 Why are experimental research designs held in such high regard
G8 Compare and contrast experimental quasi-experimental and correlational research
designs What characteristics separate these three designs What are their
advantages and disadvantages especially in comparison to one another
G9 What is the difference between a within-subjects experimental design and a
between-subjects experimental design When might a within-subjects design be
appropriate When might it be inappropriate
G10 Describe the difference between a basic within subjects and between subjects
experimental design What are the advantages and disadvantages of each
especially in comparison to one another Give an example from your area of
research in which each would be appropriate
G11 What are the major threats to the internal validity of a pretest - post test
nonequivalent control group design How can this design be improved with regard
to increasing a researchers ability to make causal inferences
G12 A production manager is interested in testing the hypotheses that participation in
quality circle programs will result in increased productivity and reduced
absenteeism A questionnaire is administered to a group of 92 employees
concerning their attitudes toward such programs and 46 with the most favorable
attitudes who are willing to participate are selected for the treatment group The
remaining 46 are the control group Measures of performance (unitsmonth for the
group) and absenteeism (lost daysmonth for the group) are kept over a three month
period during which the treatment group has weekly quality circle meetings The
results are as follows
Month 1 Month 2 Month 3 Month 1 Month 2 Month 3
Performance Absenteeism
Treatment 100 115 121 6 9 4
Control 110 108 113 6 8 5
The manager calculates t tests between month 1 and 3 The only significant
difference is performance for the treatment group so the manager concludes that
quality circles raise productivity but do not have an effect on absenteeism What
are the primary threats to internal and external validity in this study What are
possible alternative explanations for the differences (or lack of differences)
between the two groups What additional information might help explain these
results
G13 One stream of current strategy research contains event studies In these studies
investigators basically correlate the reaction of a financial market to the presence
andor absence of the occurrence of some event at a firm (eg the resignation of a
CEO) In a different approach to such a study suppose that one investigator (Jean)
conducts a natural field experiment on the effects of competitor mergers on a
firms environmental scanning activity Through previous arrangement Jean has
been working with 5 medium-sized computer hardware and 5 medium- sized
software firms on the west coast Shes been collecting a paper trail of internal
memos reports and phone calls that might measure environmental scanning
activity Shes been finding that the firms in both industries do about the same
amount of scanning (no significant differences) However in the midst of her data
collection Norton announces a merger with Symantec (software) A year later
Jean compares the amount of post-merger environmental scanning in the software
industry with that in hardware industry Just as Jean had hypothesized a t-test
shows a greater amount of post-merger scanning among the software firms She
concludes that her hypothesis was supported mergers of competitors cause an
increase in scanning
Critique the study described above in terms of its design flaws Identify the design
Jean used Briefly allude to problems the study has with external validity but
concentrate on the Cook and Campbell threats to internal validity Provide a
rationale for why each threat is or isnt operating in the study Link each of the
relevant threats to the specific constructs being studied (mergers and environmental
scanning) Finally do a summary evaluation -- what can be learned from this
study
H) Quasi-Experimental Design
H1 The University of Mississippi observed that the graduation rate of students with poor
grades during their freshman year was much lower than those with better grades
Wanting to improve the chances of these low performing students they tested the
effects of a new rule for freshmen The rule stated the following At the end of their
first semester all students with a GPA between 200 and 225 must register for
EDUC 1003 during their second semester Students with a GPA lower than 200
were put on academic probation EDUC 1003 consisted of a course whose objective
was to help students develop good study skills The theory was that poor study skills
were a significant cause of poor academic performance and that study skills could
be learned
They wanted to evaluate the effectiveness of this intervention so they collected data
on the GPAs of students beginning with their first semester and continuing through
to their third semester At that point they wanted to analyze the data to determine
whether the new rule was making a significant difference in the students academic
performance
What is the best way to analyze these data to reach an interpretable conclusion
Describe your approach and then discuss the major threats to validity that it has
Their sample size of students was as follows
Total N= 3454 (these are students who completed all 3 semesters)
Number of students with first semester grades between 200 and 225 (and thus took
EDUC 1003) was 956
H2 A nationwide furniture company wants to determine if a diversity training
program will improve individual sales performance on the floors of its urban retail
outlets A group of 45 salespeople in one city were given two weeks of training
Measures of individual sales performance were taken once two months prior to the
program and once two months after Forty-five salespeople (who did not receive the
training) in a similar city had the same measures taken at approximately the same
points in time The training group increased their average weekly sales from $14000
to $16500 while the non-training group improved theirs from $13000 to $14500
The change for the training group is statistically significant the change for the non-
training group is not
How would the interpretation of these results in this quasi-experimental design
differ from a true experimental design What are the threats to internal validity in
the above study and how might they be operating (be specific) What additional
information and analyses would be useful in controlling for these threats
H3 An accounting firm is interested in determining if a re-training program will reduce
errors made by its audit teams A group of 45 auditors in the home office location
are given two weeks of re-training Measures of the frequency of detectable errors
are taken once two months prior to the program and once two months after Forty-
five auditors in similar office at a branch location have similar measures taken at
approximately the same points in time The training group reduced their average
number of errors per audit from 8 to 3 while the non-training group reduced theirs
from 11 to 9 The change for the training group is statistically significant the change
for the non-training group is not
How would the interpretation of these results in this quasi-experimental design
differ from a true experimental design What are the threats to internal validity in
the above study and how might they be operating (be specific) What additional
information and analyses would be useful in controlling for these threats
H4 Describe the main classes of threats to validity that are found in quasi-experimental
research designs
H5 Dr Delta an organizational development consultant was hired by a firm that has
600 pizza parlors nationwide to assist in implementing organizational changes that
he hopes will result in higher levels of job involvement At the outset of the study
subjects had jobs with very low levels of enrichment and were paid on an hourly
basis He designed an experiment in which stores were randomly assigned to one of
three treatment conditions Condition 1 subjects experienced job enrichment (JE)
and a change to performance-based pay (PBP) Condition 2 subjects experienced
only JE and Condition 3 subjects experienced only PBP The parlors were
sufficiently far apart from one another and communication among the parlors so
poor that subjects in any parlor were totally unaware of changes made in other
parlors At the end of 18 months he measured the job involvement levels of workers
and then tested for differences between the three conditions using a standard one-
way analysis of variance In view of Dr Deltas design answer the following
questions
How sound is Dr Deltas design Comment on the weaknesses of the design
I) Interrupted Time Series Design
I1 What threats to internal validity are and are not ruled out by an interrupted time series
design that includes the introduction of a treatment and its removal at a subsequent
time period List and explain In the process be certain that you provide a diagram
that illustrates such a design
J) Validity Some Questions are about the validity of a measure others about experimental validity)
10) Identify four threats to internal validity and briefly describe what they mean
J1 It was some time ago that the tripartite view of validity was abandoned in favor of a
unitarian view in which different evidentiary bases for validity might be put forward
Binning amp Barrett (1989) represent an attempt to place multiple evidentiary bases into a
single framework Cook amp Campbell (1979) describe four aspects of validity but they
arent really meant to represent evidentiary bases Adding to the confusion is the fact
that while Binning amp Barrett and Cook amp Campbell use some of the same terms these
two pairs of authors clearly mean different things by these terms and intend for them to
be used in different ways Your task is to 1) Describe the evidentiary bases discussed
by Binning amp Barrett 2) Describe the aspects of validity described by Cook amp
Campbell 3) Describe the similarities and differences between the two lists including
the different purposes served by the two lists and 4) Present a single framework that
incorporates both This last task is the most important of the four
J2 What are the types of validity How would each affect an empirical study IC
J3 Define both internal and external validity Which is more important (it is not okay to
say that they are equally important) Defend your reasoning
J4 Why might someone argue that the construct validity of a measure can never really be
established
J5 Describe each of the following forms of validity content convergent discriminant
criterion-related and construct How is each assessed How do they related to each
other Which is most important (Make sure you defend your answer)
J6 Define and explain 6 of the 8 types of validity listed below and describe the type(s) of
information each provides Choose one specific type of study as an example (eg
cross-sectional study experiment quasi-experiment simulation ethnography etc) and
compare and contrast the usefulness and importance of each type of validity for that
type of study
-- Concurrent validity
-- Construct validity
-- Content validity
-- Convergent validity
-- Discriminant validity
-- Statistical conclusion validity
-- Internal validity
-- External validity
J7 Designing empirical research has been called making a series of trade-offs
Unfortunately decisions that are made to increase one desired quality (like internal
validity) can also decrease another desired quality (like external validity) For each of
the issues below discuss the concerns involved (ie the trade-off) and identify the
qualities that are being increased or decreased
a laboratory vs field study
b using a 5-item measure vs a 1-item measure
c using a student sample vs a sample of full-time employees
d using a sample of employees from one company of 5000 vs 500 employees from
each of 10 companies
e collecting your data using one method vs collecting your data using multiple
methods
J8 There are four major types of validity in social science internal validity external
validity construct validity and statistical conclusion validity Please address the
following three issues concerning validity
a What is the meaning of the four major forms of validity (ie internal and external
validity construct validity statistical conclusion validity)
b Are there trade-offs that can or must be made among the four types of validity
d Describe how the concept of validity varies across the research traditions of
experimental vs observational research
IC
J9 The quality of research is often assessed by examining validity issues As you are
aware there are numerous typesforms of validity (eg internal and external validity
construct validity statistical conclusion validity) These types of validity address
different aspects of the research process For this question please address the following
issues
a What is the meaning of the four major forms of validity (ie internal and external
validity construct validity statistical conclusion validity)
b Should there be a priority among these forms of validity If yes why If no why not
c Does the concept of validity vary across research traditions (ie experimental vs
observational research) If yes why If no why not
J10 External validity has received considerable attention in the social and behavioral
sciences Some researchers argue we are too concerned with the external validity of our
findings while other researchers argue that we are too unconcerned with external
validity Several points of view have been developed to explain what is external
validity When answering this question please be sure to address at least the following
issues
a Compare and contrast alternative conceptualizations of external validity
b Some researchers have argued that the role of external validity is invariant across
research traditions (ie experimental vs observational research) Defend the
perspective that the role external validity is invariant across these two research
traditions In addition present the weaknesses of this perspective
J11 In designing a research study researchers must consider trade-offs between internal and
external validity Explain what is meant by internal validity and external validity What
is the nature of these trade-offs How would you evaluatedetermine which is more
important internal or external validity for a particular study Why is this such an
important issue in organizational studies
J12 A researcher conducted a quasi-experiment to test the effects of participative decision
making (PDM) on job attitudes of employees Employees from different departments in
a large organization were assigned to either a treatment group (PDM implemented) or a
control group (no PDM) Random assignment was not possible because of work
schedules coordination of tasks etc Thus the design can be considered an untreated
control group design with pretest and posttest and is represented as follows (where
O=observation X = treatment)
________________
O1 X O2

The results of the experiment are presented in the graph below [no graph provided]
The dependent variable is job satisfaction and is measured on a 100 point scale (with
100 being extremely satisfied) How amenable are these results to causal interpretation
What is (are) the major threat(s) to internal validity B if any B for this type of design
given these results What steps can be taken to assess the extent of this (these)
threat(s)
K) Data Collection Methods
14) Describe the various methods of data collection (eg survey interview observation etc)
available to a social scientist What are the advantages and disadvantages of each relative to
each other
K1 Within micro organizational research much criticism has been raised concerning
the reliance on self-report survey data What potential problems does self-report
survey research raise How big of a problem do you think this is
K2 There are a number of methods for collecting data (eg survey interview archival
etc) that are available to a social scientistorganizational researcher Discuss each in
terms of their strengths and weaknesses both on their own and in comparison to one
another
K3 Pick an important construct in your favorite area of management research for which
there is some controversy about how it should be measured or operationalized (eg
environmental munificence or growth need strength) Give the prevailing verbal
definition of the construct and analyze the measurement controversy from two
broad angles First discuss how the controversy may or may not stem from claims
about how one measure is better or worse than another because it (or the other) is an
(a) archival record (b) direct observation (c) social report or (d) self-report That is
what are the relative strengths and weaknesses of each of these types of
measurement for the construct youre discussing Second discuss the construct
validity of the most commonly used measure(s) of this construct To answer this
second part you need to discuss just what construct validity is and how it can or
cannot be demonstrated In the situation you describe what could be done to
demonstrate or improve the construct validity of existing measures
K4 Interviewing in some form has been the workhorse for data collection in a variety
of research traditions positivistquantitative ethnographic feministpost-modernist
and increasingly historical research While each tradition elicits information from
respondents the goals and processes involved in interviewing vary considerably
across research traditions Discuss the purposes of the interview the relationship
between data and theory the roles assumed by the interviewer and the respondent
and the relevant criteria for assessing the validity and reliability of the information
obtained In addition compare and contrast the use of the interview as a data
collection method in the positivistquantitative tradition with its use in one of the
alternative traditions
L) Common Method Variance
L1 Many of us have had concerns about the reviews of our survey research which
suggest that data analyses of surveys are biased because of common method
variance effects of individual differences such as negative mood negative
affectivity and social desirability and the reliability and validity of the constructs
we are attempting to measure Define how these problems affect a research issue in
organizational behavior and the steps that might be taken to minimize such potential
criticisms of papers based on analyses of self-reported data through survey
instruments
L2 In a series of papers by Spector (1994) Schmitt (1994) and Howard (1994)
published in the Journal of Organizational Behavior arguments were provided for
and against the use of self-report questionnaire measures One of the issues
discussed that could limit conclusions drawn from relationships observed using self-
report measures was method variance What is meant by method variance what are
its sources and what impact is it expected to have on research findings
M) Sampling
M1 The manufacturing census samples all plants of 250 employees or more For
plants of 5-249 employees it takes a size proportional sample Plants of 1-4
employees are not sampled What challenges does this sampling method provide
to researchers What could you do to account for these problems if you were
TH
studying organizational (not plant) growth
M2 New York State has approximately 250000 employees in over 70 state agencies
commissions and boards ranging in size from approximately 50 to over 5000
employees Assume that you wanted to draw a representative sample of 1000
employees Describe two ways that you could draw such a sample and briefly
describe the advantages and disadvantages of each of these sampling approaches
IC
M3 The director of a national non-profit agency with approximately 10000
employees located primarily in regional offices in each of the 50 states the
United States has approached you and asked you to develop a study
(organizational survey) of organizational culture within the agency The agency
is about to embark on a variety of change initiatives including developing team
structures and the study is meant to examine various elements of organizational
culture that are potential barriers to change The director has indicated that he
would like to have the data analyzed at both the individual and office level of
analysis Because of funding limitations the agency will only be able to send the
survey to 1000 employees The director has indicated that there are three ways
of sorting employees all employees listed alphabetically all employees listed
alphabetically by state and all employees listed alphabetically by region (there
are between five and ten regions per state) Given these three ways of sorting
employees describe at least three different sampling approaches and the
advantages and disadvantages of each
M4 In your role as Teacher of Organizational Studies you are asked to prepare a
tutorial for beginning doctoral students on sampling design Assume that this
tutorial is part of a basic class in research design and that students in this class
have had a basic statistics course up to and including multiple regression Your
tutorial should focus on briefly defining and explaining the differences between
probability and non-probability samples You should make sure to present and
describe several types of probability samples (eg random systematic
stratified etc) and non-probability samples (eg convenience snow-ball quota
etc) and discuss general principles for when to use a probability vs a non-
probability sampling design For each sampling design you should also provide
at least one clear example of a situation where this type of sampling design is
appropriate
N) Cross-Cultural Research
N1 Discuss the problems in conducting cross-culturalnational comparison in terms
of (1) conceptualization and (2) research design and data collection
Define the three levels of measurement invariance How would the problems that
you have identified in part (a) affect measurement invariance How would you
examine measurement invariance by confirmatory factor analysis
TH
N2 Explain why using national boundaries as independent variable in cross-cultural
studies may not be appropriate in terms of theory and research methods What
alternative ways would you recommend
IC
O) General
O1 In your readings research has been described as choices among conflicting goals
(desiderata) For instance when choosing among research strategies a researcher
must choose among the desiderata of precision realism and generalizability The
trade-offs among desiderata occur for all aspects of research that is for the selection
of theories the treatment of independent variables research strategies the selection
of the problem to study rules of evidence for determining the meaningfulness of a
research finding and even the frameworks that describe the research process
Discuss what you see as the major trade-offs for each of the following aspects of
research That is discuss what you see as the major strengths and weaknesses
(advantages and disadvantages) of each aspect
a The trade-offs between internal and external validity
b The manipulation of the independent variable vs the observation of the
independent variable
c Basic vs applied research
3 DESIGNING A RESEARCH STUDY
A) General (Research Design)
3) Why is control so important in research design What are the different ways it can be
achieved (give a brief description of each control method) What are advantages and
disadvantages of each
A1 It has become almost a truism to note that the choice of methods influences theory
and questions data and conclusions (the causal direction might also be reversed)
Briefly discuss how the methods used have influenced research in any two of the
following areas leadership power and politics organization culture organization
justice Compare and contrast as possible Suggest some potentially fruitful
methodological directions for future work in these same topical areas and dont be
shy about reflecting on broader issues of how the field of organizational behavior
constructs its realities Lastly tie your discussion and reflections back to your own
future as a researcher what lessons or guidance do you derive from your
understanding of these issues
A2 Characterize as fully as possible what you see to be the methodological approach or
approaches in strategic management research Is there a dominant method or a wide
variety Discuss the reasons for the situation What are the advantages benefits etc
of the approach(es) in use What assumptions (ontological epistemological
ideological) do they embody Are current efforts ideal or at least adequate Are
there other approaches that could be useful If so how might researchers be
encouraged to use these as well If you see no advantage to more variety in
methodological approach support that point of view
A3 Describe a research question or area of interest to you and why you think it is not
only of interest but significance Using your understanding of research methodology
describe two ways of pursing the question that are as divergent on as many
dimensions as you can imagine Describe the advantages and disadvantages of each
approach How strong a link or fit is there between a research question and a
method
A4 In his 1957 article entitled The two disciplines of scientific psychology Cronbach
discussed the assumptions goals and methods used in experimental methods and
correlational methods in psychology
a According to Cronbach what is the main difference between the two disciplines
b Discuss the strength and weaknesses of each discipline
c What if anything could be done to improve the situation
B) Designing a Research Study
B1 Cook and Campbell describe the experiment as the research design with the
greatest methodological rigor However given the constraints present in most
organizations I-O Psychologists cannot often conduct experiments in applied
settings and must settle for techniques with less control than experiments
Describe a study to investigate the relationship between participation in a
supervisor training program and work performance which could realistically be
conducted in an organization If an experiment is not possible describe how you
would go about maximizing your ability to draw valid conclusions from your
design
B2 The XYZ Co has recently developed a sexual harassment web-based training
program The developers claim the program will cut training time and costs and
will be as effective or more effective than classroom-based sessions They
believe that this will be due to the increased availability of the program and the
ability for participants to review program material on demand Before the XYZ
Co developers launch this product they want you to determine if their claims
have merit Explain how you would design a study for this purpose
B3 Research suggests that demographic diversity improves group creativity but
reduces group efficiency Some argue that demographic diversity is just a proxy
for value and experience diversity and that demographic diversity on its own is
meaningless Design a test to settle this argument
TH
B4 E-mail has become a common form of communication in organizations and is
used for both formal and informal communication Because it has become so
IC
popular some people complain that the frequent use of e-mail leads to
miscommunication because they receive communications in e-mail that should
be accomplished through face-to-face or telephone conversations where there is
an opportunity for interaction You are interested in looking at this
phenomenon You are most interested in describing how e-mail is used for both
formal and informal communication and in examining the effect of the e-mail
use on organizational communication effectiveness Design empirical research
to address those issues
Describe your study in detail thoroughly explaining the research design
sampling plan data collection procedures ethical issues and proposed data
analysis for your research design Be sure to discuss the internal and external
validity of your research Which validity threats are ruled out and which
remain
REMEMBER Be thorough Your research design should demonstrate that you
are a competent researcher who is knowledgeable about the proposed research
methodology or methodologies Therefore be sure that you carefully describe
and give technical explanations for each component of your research
B5 Choose a specific situation involving employee selection eg artists for an
advertising agency (a) What strategy would you use in selecting the selection
measures (b) How would you combine the measures eg which measures
would you combine in a compensatory manner and which is a noncompensatory
manner (c) How would you assume test fairness defining various measures of
the term (d) How would you make final selections (e) How would you
validate your procedure (f) What considerations would enter in if your
company were too small to provide validation data (g) What difference would
it make if you were developing a procedure for deciding whether trainees
should be promoted as opposed to making new hires Please note--emphasize
but do not limit yourself to statistical issues
B6 There is evidence in the marketing literature of a non-monotonic relationship
between the expectations that customers have for retail service and their
eventual level of satisfaction with that service That is as a customers
expectations for service increase so does their eventual service satisfaction --
up to a point After that point the greater the expectations the lower the
eventual satisfaction Develop a hypothesis that includes a moderator variable
that might account for this evidence Give some reasonable rationale for it State
your hypothesis verbally as an equation as a directed graph (circle amp arrow
diagram) and as an X-Y function chart Discuss how it would or would not be
possible or useful to test your hypothesis via a laboratory experiment In your
discussion cover how and why a researcher could (not) manipulate the
independent constructs involved (mode X) whether or not random assignment
to conditions (mode R) is possible (including how may conditions would be
necessary) which alternative constructs could or could not be controlled (mode
K) and which constructs should be measured (mode Y)
B7 Assume you are the chairperson of a committee that must evaluate
undergraduate programs at your university Your task as chairperson is to
devise an approach (a design a research strategy a set of measures) that will
allow you to evaluate undergraduate programs Make sure that your approach
can be used in the future and at other comparable universities When developing
your plan be sure to address at least the following issues
a the type of design you would select Compare and contrast the selected design
with another possible design
b the type of research strategy you would select Compare and contrast with
another possible strategies
c discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
B8 Assume you are an organizational research design expert assigned to the
Strategic Planning Department of a large multi-national manufacturing firm
The Department has developed a new PC-based software package called
STRATPACK The software (and a one-week training course to learn how to
use it) is intended to improve the long-range planning ability of middle and
upper-level managers
Your job as research design expert is to devise research (a design a research
strategy a set of measures) that will allow you to evaluate the effectiveness of
the STRATPACK program Describe a research design for evaluating the
program Make sure that your research approach can be used in the future and at
all sites in the company When developing your plan be sure to address at least
the following issues
a discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
b the type of design you would select (eg a design where you manipulate the
independent variable versus observe the independent variable) Compare and
contrast the selected design with another possible design
c how your design deals with the major forms of validity Be sure to examine at
least internal external and construct validity
B9 Assume you are a consultant hired to evaluate the effectiveness of an industrial
safety program undertaken by a large manufacturing organization The safety
program is a behavioral one that provides rewards such as monetary bonuses or
extra paid vacation days for safety behaviors in terms of accident-free days
weeks etc Your task is to devise an approach (a research strategy a design a
set of measures and a general analysis strategy) that will allow you to evaluate
the safety program Because of the potential for the influence of many
extraneous variables on any safety program it is difficult to design research a
single cross-sectional study than can evaluate the impact of a single safety
program How would you design a study to evaluate the impact of the safety
program When developing your plan be sure to address at least the following
issues
a the type of research strategy you would select Compare and contrast with
another possible strategies
b the type of design you would select Compare and contrast the selected design
with another possible design
c discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
B10 One of the most important areas of research is forecasting of human resources
needs based on strategic positions of organizations For example NY State must
carefully forecast its human resources needs as it proceeds with significant lay-
offs of state employees Future human resources needs are generally evaluated
by either statistical ie regression or simulation or clinical judgment i e
supervisors judgments methods
a Design a single study that addresses the empirical question of whether
statistical or judgmental methods are better for forecasting human resources
needs You may discuss a program of research but please be quite specific in
your description of the first study
b What are the critical methodological issues in doing this kind of research
c What are the critical applied (or practical) issues in doing this research
d Are the issues in b and c related
B11 In the past decade computinginformation technology has changed many
aspects of organizational life For example the technology can make increased
decentralization possible by improving communication between central offices
and field offices Computer networks and word processors can enhance group
empowerment by making it possible for team members to create and edit
written group products quickly even if the individuals are at different locations
Some have argued that computinginformation technology will foster the
paperless productive office nevertheless others argue that the technology only
increases paper and reduces office productivity You are applying to the
National Science Foundation for a grant to conduct research that examines the
impact of computing information technology on organizational decision
processes The NSF application procedure imposes five basic requirements that
your research design must fulfill in order to receive funding Note A very
significant factor affecting NSF grant decisions is a clear demonstration that the
researcher is knowledgeable about the research methodology used Write your
response to each of the following five grant requirements Be sure not only to
respond to the requirement but also to demonstrate your research
competence
1You must design a study that uses two different methods
(interviewobservation survey experiment or quasi-experiment) Describe your
two methods in detail and provide a rationale for the key elements (eg
sampling data collection proposed analysis) of your methods Be sure to
discuss and evaluate the internal and external validity of both methods
2 As part of your research design you must select a conceptual (latent) variable
central to your proposal (use centralization of decision making as your
variable) and describe how you will develop your own measure (You may not
simply use off the shelf instruments)
3 You must describe how you will test for the reliability of the measure
(centralization of decision making) you developed in step 2 The NSF insists
that you describe how you will evaluate both the temporal stability and the
internal consistency of your measure Be sure to discuss what temporal stability
and internal reliability mean and how they are related
4You must describe how you will assess the validity of the measure
(centralization of decision making) you developed in step 2
5 NSF requires a brief statement and defense of the philosophy of science
underlying your research Discuss your position and show how your research
design is consistent with your philosophy
B12 Many organizations in the United States economy have installed some form of
Empowered Teams as an alternative or supplement to traditional bureaucratic
structure Preliminary evidence of the effectiveness of empowered teams
however is mixed--some organizations have claimed success and others have
reported failures The evidence however is predominantly anecdotal--written
for trade magazines by the organizations themselves There are few rigorous
empirical studies assessing the effectiveness of empowered or self-managed
teams You are applying to the United States Department of Labor (USDOL) for
a grant to conduct research that examines the effectiveness of empowered
teams The application procedure of the USDOL imposes three requirements
that your research design must fulfill in order to receive funding Write your
response to each of the three grant requirements The importance of each section
is implied by the evaluation points allocated by the USDOL to each of the three
requirements given in parentheses
1 (50 points) Your study design for assessing Empowered Team effectiveness
must use two different methods (interview observation archival analysis
survey simulation experiment or quasi-experiment) Describe in detail and
thoroughly explain the sampling plan instrumentation data collection
procedures and proposed data analyses for both methods Be sure to discuss the
internal and external validity of both methods and how the two methods
complement one another
2 (30 points) As part of your research design you must select one conceptual
(latent) variable central to your proposal and describe how you will develop
your own operationalization of the measure (You may not simply use off the
shelf instruments) Use the concept of group morale to demonstrate your
operationalization methodology Be sure to explain very explicitly to the
USDOL how you will assess the validity and reliability of the group morale
measure you are developing
3 (20 points) The USDOL traditionally has funded research conducted only
within the general paradigm of logical positivism but now is more open to other
research paradigms as well Your grant proposal must provide a statement and
defense of the explicit philosophy of science underlying your research Describe
your philosophy of science and show how your research design is consistent
with your philosophy
REMEMBER Be thorough You not only must design effective research but
you also must demonstrate to the USDOL that you are a competent researcher
It is absolutely vital to the USDOL that the principal researcher is
knowledgeable about the proposed research methodologies Therefore be sure
that you always carefully describe and give technical explanations for each
component of your research design and explain all technical terms (eg
Cronbach alpha KR-20 Likert scale)
B13 Assume that you are working as part of a research team that is responding to a
RFP (Request for Proposals) from a funding agency for research on work
socialization and newcomer adjustment The RFP calls for rigorous field
research that tests the effectiveness of theory-based interventions aimed at
facilitating the adjustment of new organizational members to complex andor
stressful work conditions The major goal of your teams research is to test the
effectiveness of a self-regulation intervention which trains newcomers to
identify and use relevant social information and cues to regulate work behavior
Your group hypothesizes that self-regulation training will be more effective
than other common treatments or interventions (eg realistic job previews
institutionalized socialization tactics)
You have been included in the team because of your methodological expertise
Your role is to design a rigorous field experiment or quasi-experiment to test he
effectiveness of the self-regulation training program REMEMBER THE
MAJOR CRITERION FOR FUNDING IS THE RIGOR OF THE RESEARCH
DESIGN Design a field study to include in the grant proposal Your proposal
should contain the following two sections
1 Study Design Construct and describe in detail an experimental or quasi-
experimental design to test the effectiveness of your intervention Describe in
detail the experimental groups (including how they will be constructed) the
research setting the sampling plan for study participants the treatment
manipulation and the data collection procedures Also indicate any control or
nuisance variables that may be measured
After describing the procedures write a justification of the design What threats
to validity does it rule out or limit and what threats to validity remain
II Measurement Describe the steps you would take to achieve valid and
reliable measure of the latent (conceptual) variable worker adjustment Your
team feels that as part of the proposal you must develop an original
operationalization of adjustment (thus you cannot simply use existing off the
shelf measures) Indicate in adequate detail how you would operationalize the
measure and indicate how you would demonstrate reliability and validity
B14 In describing their notion of the collective mind Karl E Weick and Karlene H
Roberts note Our focus is at once on individuals and the collective since only
individuals can contribute to a collective mind but a collective mind is distinct
from an individual because it inheres in the pattern of interrelated activities
among many people (p 360) Collective mind is not indexed by within-group
similarity of attitudes ideas or activities A collective mind is one in which
many people or many groups integrate their different attitudes ideas and
activities heedfully As Weick and Roberts note People act heedfully when
they act more or less carefully critically consistently purposefully attentively
studiously vigilantly conscientiously pertinaciously (p 361)
The idea of the collective mind as heedful interrelating is developed in the
following excerpt When people make efforts to interrelate these efforts can
range from heedful to heedless The more heed reflected in a pattern of
interrelations the more developed the collective mind and the greater the
capability to comprehend unexpected events that evolve rapidly in unexpected
ways When we say that a collective mind comprehends unexpected events we
mean that heedful interrelating connects sufficient know-how to meet situational
demands For organizations concerned with reliability those developments
often consist of unexpected non-sequential interaction (p366)
An example of heedful interrelating occurs as a pilot lands herhis aircraft on the
deck of an aircraft carrier The pilot does not actually land She is recovered
A recovery is an interrelated set of activities among air traffic controllers
landing signal officers the control tower navigators deck hands the helmsman
driving the ship etc These activities can be interrelated more or less heedfully
depending on the care with which the different units contribute represent the
situation and subordinate their activities to the single purpose of successful
recovery (p 363)
You are to design a two-part study
Part I You are to design a measurement study which assesses heedful
interrelating (ie collective mind) with a quantitative measure in a replication
of an aircraft carrier flight deck or other situation of your choosing Describe
your research strategies including operationalization of the variable selection of
the sample subjects data collection data analysis and so on for the purpose of
developing a measure of heedful interrelating
Part II Using the measurement tool developed in Part I and any other tools as
needed describe how you would design a study which would compare heedful
interrelating across organizations Choose at least one macro-organizational
variable (eg technology environment) as your basis of comparison Here you
must describe how you would make your selection of organizations to be
compared your data collection procedure data analysis and so on
B15 Many organizations in the United States have installed cross-functional teams to
counteract the silo mentality of traditional bureaucratic structure Preliminary
evidence of the effectiveness of cross-functional teams however is mixed --
some organizations have claimed success and others have reported failures The
evidence moreover is predominantly anecdotal--written for trade magazines by
the organizations themselves Since there have been few rigorous empirical
field studies assessing the effectiveness of cross functional teams the National
Science Foundation has decided to fund research on the topic
Assume that you are submitting a research proposal to NSF for a grant to
research the effectiveness of cross-functional teams Describe in detail and
thoroughly explain the research design sampling plan data collection
procedures ethical issues and proposed data analysis for your research design

validity threats are ruled out and which remain NSF also requires that you
provide a statement and defense of the explicit philosophy of science underlying
your research Describe your philosophy of science and discuss how your
research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but

5 MEASUREMENT
A) Measurement Terms
A1 There are four levels of measurement rigor in management research Discuss each
one What properties do measurements at each level have (ie how much
information do the numbers from each level of measurement convey) How can the
numbers be changed (transformed) and still retain the properties of their
measurement level Pick one construct from a favorite research domain and give an
example of an operationalization of that construct at each of the four levels of
measurement rigor (provide arguments about why you think those examples reflect
each level) Lastly treat each examplelevel as a dependent variable in some
statistical analysis Given an example of a statistical technique appropriate for
analyzing data at that level of measurement rigor
A2 Define (and discuss important features or issues concerning) the following
constructs measurement (Define any six terms)
1 Construct validity 6 Item analysis

estate agents self-assessment of performance Since there is no existing
measurement available you have to develop the instrument by yourself
Describe how you would develop the measurement assuming that you have no
idea of how many dimension the construct has
b) Suppose you have developed an instrument consists of 20 questions
measuring 4 dimensions (5 items per dimension) from (a) You collected data
from another 300 real estate agents to validate your instrument Explain how
TH
you would use structural equations model (SEM) to examine the reliability and
validity of the instrument What are other concerns about reliability and validity
that are not addressed by this approach
B2 The research and business world have been fascinated with the concept of
organizational culture However operationalizing this construct has been a
difficult task Discuss the ways in which the construct has been operationalized
(eg technique static v dynamic sample selection generalizability) Critically
analyze each of these methodologies Then choose a methodology you would
use to examine organizational culture and defend your choice Describe how
you would study culture and what more would be known about culture as a
result of your study
B3 Suppose you are setting out to develop a new measure of a construct You want
this measure to be used in survey research and you want to establish its validity
and reliability Your goal is to have at the end of the process a measure that is
defensible and likely to be widely accepted by other researchers studying that
construct What steps would you take to conduct such a program of research
For each step explain the purpose of that step explain why that step is
important explain what methods and statistical procedures you would employ at
each step and explain what evidence you would hope to gather at each step

relevant variable from your field) Detail the major concerns that need to be
addressed and the steps that need to be taken in working toward validating this
new measure
B5 Assume that you recently read an article on workplace violence which you
found very interesting The authors argued that one of the predictors of
workplace violence was a construct called propensity to be violent and used a
one-item measure as follows How likely are you to become violent when
provoked You had serious doubts about the authors measure and decided to
develop your own
(a) How would you go about developing items to measure propensity to be
violent
(b) How would you determine whether the instrument was reliable
How would you determine whether the instrument was valid
B6 A concern in organizations is retirement of baby boomers within the next 5 -
10 years This concern is focused on the loss of older employees with skills
critical to the core business functions of organizations In order to continue to
have employees with those critical skills it seems necessary to retrain some
older workers However past practice in most organizations has been not to
retrain older workers for a variety of reasons mostly financial A researcher
working for the Human Resources Department of a large corporation - 13500
employees in 12 different plant locations - hypothesizes that the major reason
for not retraining older workers is ingrained in the culture of the corporation
IC
The researcher feels that older workers are not as highly valued as younger
workers in terms of their potential usefulness after retraining The researcher
searched the literature but found nothing in the existing literature to measure
the cultural value construct What should the researcher do to establish a reliable
and valid self-administered paper and pencil measure of this construct namely
the value of retraining older workers

of the concept of technological complexity What standards would you use to
determine if your operationalization is valid
B8 Organizational researchers have several strategies available to them for
gathering information (eg self-report measures archival measures direct
observation and trace measures) Assume that you are going to conduct
empirical research to assess the role that the structure of the organization plays
in determining the level of organizational effectiveness Briefly review the
strengths and weaknesses of the basic strategies (that is self-report measures
archival measures direct observation and trace measures) for measuring
organizational effectiveness Next describe and justify the steps you would
take to develop an operationalization of the concept of organizational
effectiveness What standards and procedures would you use to determine if
your operationalization is valid
B9 One of the most important topics of recent research has been stress in the work
place One of the most important problems with understanding this literature is
the varying definitions and measurement of this construct Suppose you had
decided to investigate the relationship between stress at the work place and dual
career family happiness

your meaning of validity and reliability It is important that your measure have
all the necessary psychometric characteristics so that other scientist can trust the
results of your research

measure of stress at work with other measures of this construct How would you
do that

impact of interpersonal trust on organizational decision making Describe and
justify the steps you might follow to develop an operationalization of the
interpersonal trust concept

Further assume that you have used previous literature and your own conceptual
development to delineate 2 dimensions of X specifically XF1 and XF2
Describe the steps you would go through in developing testing and evaluating
this new scale With regard to testing and evaluating be sure to consider the
role of factor analysis (both exploratory and confirmatory) and item analysis
Also you will want to make sure that your new multidimensional scale shows
evidence of validity (several kinds) and reliability so be sure to examine these
issues and explain how specific information gathered from the above testing
contributes to these concerns

measure
C9 Define reliability Name some methods of calculating reliability How well do
these methods map up with the definition of reliability What is the impact of the
number of test items and sample size on Chronbachs alpha and why would this
effect occur or not occur (Note Do NOT discuss inter-rater reliability)
C10 Schmidt and Hunter (1996) described several types of measures typically used in
organizational research and identified the type(s) of measurement error affecting
each of them in various situations For each measure below indicate the types of
error and sources of error that are most likely to affect it Then indicate what
could be done to reduce errors of measurement andor what can be done to
control for errors statistically
a Supervisor ratings of subordinates job performance
b Self-ratings of ones own job performance
c Self-reports of ones own job-related attitudes

worker)
d Aptitude tests taken as part of the hiring process
C11 Suppose you had conducted research on the relationship between organizational
commitment and rigidity of organizational structure in 200 firms Your measure
of rigidity was based on number of organizational authority levels and the degree
to which written organizational rules existed and defined role behaviors for
employees Thus an organization with a large number of organizational levels
and specific written policies defining appropriate role behaviors for employees
would score high on rigidity of organizational structure After analyzing your
data you find that there is a statistically significant negative correlation between
commitment and rigidity which is consistent with your hypothesis However the
reliabilities for your two measures are
(1) commitment = 23 (2) rigidity = 83
How should you interpret your results What could you do to fix this situation
Describe the specific steps (in order) you would follow to develop a more
reliable measure of commitment

interrater agreement and reliability methods be used (Rwg Kappa and Weighted
Kappa percent agreement average pairwise correlation ANOVA methods
(interclass correlation coefficient WABA)) What are the advantages and
disadvantages of each of the methods
(b) Explain the controversy between Frank Schmidt Larry James and others
regarding the differences between interrater agreement and interrater reliability

data
(e) Provide some ideas for avoiding the need to aggregate in group-level research

research literature This type of research raises many issues and presents many
challenges in terms of designing the research measuring variables and collecting
and analyzing the data Assume that you are interested in aggregating data (eg
from the individual to the group or from the firm to the industry) for one or more
variables What are the major issues you will need to deal with
D3 A researcher wants to measure organizational climate for continuous learning
Organizational climate is operationalized as a shared consensual aspect of the
organization -- the shared perception among employees that the organization values
and supports continuous learning Describe how you would measure organizational
climate in this case Specify (a) the level (ie individual group organization) at
which the construct exists (b) the level at which you would measure the construct
and (c) the procedures that you would use to establish that measurement is aligned
with theory (ie the construct validity of the measure)
E) General (Measurement)
E1 Studies in organizational behavior research often rely on single-item measures of
key constructs The use of single-item measures has long been criticized based
on the premise that single-item measures are unreliable However Wanous
(Wanous amp Hudy 2001 Wanous amp Reichers 1996 Wanous Reichers amp Hudy
1997) has recently argued that single-item measures can exhibit adequate
reliability Wanous based this conclusion on a procedure for estimating the
reliability of single-item measures using the classic formula for correction for
attenuation Subsequent studies have yielded mixed results regarding the
conclusions of Wanous (eg Loo amp Kells 1998 Nagy 2002) and the veracity
of the perspective advocated by Wanous remains in question Summarize and
assess the arguments for and against the use of single-item measures and
evaluate the procedure and evidence offered by Wanous regarding the reliability
of single-item measures Based on your assessment and evaluation develop
recommendations regarding the use of single-item measures in organizational
behavior research

E2 Ipsative measures have become prevalent in organizational behavior research
Ipsative measures ask respondents to answer questions relative to one another
such that the scores for all questions sum to the same constant for all respondents
Examples of ipsative measures include rankings Q-sorts and the allocation of a
fixed number of points (eg 100) across a set of response options Ipsative
measures may be contrasted with absolute measures which ask respondents to
answer questions independently from one another Absolute measures are
exemplified by rating scales using an interval or ratio numeric response format
The relative merits of ipsative and absolute measures have been debated for
decades (eg Cornwell amp Dunlap 1994 Hicks 1970 Johnson Wood amp
Blinkhorn 1988 Saville amp Wilson 1991 1992) yet the fundamental issues
underlying this debate have not been adequately addressed in organizational
behavior research For example measures of organizational culture and values
are often ipsative and some researchers advocate these measures over absolute
measures (eg Meglino amp Ravlin 1987 OReilly Chatman amp Caldwell 1991
Ravlin amp Meglino 1987 see also Rokeach amp Ball-Rokeach 1989) Review the
relative merits of absolute and ipsative measures Based on your review which
form of measurement is most appropriate and why Do your conclusions depend
on the construct being measured If so what types of constructs are best suited to
ipsative measures and what types are best suited to absolute measures Next
apply your conclusions to the measurement of culture and values in
organizations What specific arguments have been advanced in favor of ipsative
measures of culture and values How sound are these arguments Should ipsative
measures be used in the study of organizational culture and values If not how
can absolute measures of culture and values be developed that address the
concerns voiced by advocates of ipsative measures Provide a specific example
of the type of measure you would propose

facets of a concept Although such measures are prevalent and in some cases are
advocated (eg Law et al 1998 1999) they can present a variety of conceptual
and methodological problems Describe the specific problems associated with
measures that use items representing different facets of a concept Compare these
problems with the purported advantages of such measures Conclude by

E5 Suppose Roberta Von Eisenbrick is a researcher interested in the consequences of
AFFECTIVE CONFLICT (AC) in decision-making teams She gets access to a
variety of outcomes assessment committees at each of 87 different schools in
the Dallas Independent School District and gains permission to tape-record two
of their meetings (one in February and one in March) Such committees have
been formed to develop quantitative ways to track pursuit of school goals and
provide accountability to local and state governments These are often divisive
teams with heated meetings because what gets assessed is what usually gets
rewarded After both of these meetings the committee members each
fill out a short questionnaire that contains 20 Likert-type items measuring how
much AC occurred (eg People in our group often get angry with each other)
The individual scores are summed across items then averaged across team
members to come up with a group-level AC score for each of the 87 2
meetings The same procedures are followed for a 5-item measure of Group
Cohesiveness (GC) which is predicted to be reduced by higher levels of AC
Roberta also listens to every tape and from her expert judgment she rates each
groups meetings on the same 20 items Those 20 ratings are summed for each of
the 87 2 meetings Now Roberta is interested in evaluating her measure She
wants it to have excellent psychometric properties including reliability and
construct validity

criticized the fact that psychologists rely heavily on significance testing What
are the essential elements of these critiques What are some remedies to the
problems engendered by significance testing and why have these remedies not
been widely adopted

whether we should abandon significance testing and report confidence intervals
instead Please summarize arguments from both sides and state your position on
this issue

(a) Please define both of these terms (b) Sketch a conceptual model to show how
each relates to main effects (c) Using variables of your choice please write
hypotheses to reflect both (d) Explain how each is tested analytically
D2 Discuss moderators and mediators Provide an example of how (1) a moderating
variable influences the relationship between the independent and dependent
variable and how (2) a mediating variable influences the relationship between
the independent and dependent variable Describe how you would test for both
moderation and mediation using regression
D3 Many theories in organizational research predict that the effects of one variable
on another are moderated by a third variable Such moderator effects are
typically tested by entering the product of two variables as a predictor after
controlling for the two variables that constitute the product Several researchers
have pointed out that this product is often highly correlated with the squares of
the two constituent variables and have suggested that moderating effects may be
tested after controlling not only for the two constituent variables but also their
squares (eg Cortina 1993 Ganzach 1998 Lubinski amp Humphreys 1990
MacCallum amp Mar 1995) Discuss the strengths and weaknesses of this
approach as compared to methods that use only the product term and its
constituent variables Conclude with recommendations as to when and under
what conditions organizational researchers should test moderator effects with the
squares of the constituent variables in the equation

D4 Assume you are interested in studying relationships amongst three variables X
Y and Z Your first hypothesis posits Z as a mediator of the relationship between
X and Y Your second hypothesis posits Z as a moderator of the relationship
between X and Y Draw the figures depicting each of these hypothesized
relationships and describe (make sure to write regression equations) how you
would test each of these hypotheses
D5 The amount of time and effort that the average person pours into his or her job
has risen steadily over the last two decades such that the average person now is
working one more week per year than the average person in the mid 1970s This
steady increase has fueled research interest in the construct of Job Burnout (JB)
which is an emotional and physical exhaustion associated with ones work
Organizational Stress (OS) the perception of greater demands than available
resources in ones work environment is thought to be one of the chief
antecedents of JB However time spent under OS is thought to make its affects
on JB accumulate or worsen Work Role Withdrawal (WRW) the avoidance of
responsibilities or the deliberate reduction of inputs to ones job is believed to be
the chief consequence of JB

E) Multiple Comparisons
E1 In your role as professional colleague you are called upon to advise another doctoral
student about the appropriate use of multiple comparisons and post hoc tests in
analysis of variance Your student colleague already has been introduced to ANOVA
and multiple regression Specifically you are to write out a description of how to test
for differences among the different levels or cells of a categorical variable In your
description you should discuss among other things
a the statistical and philosophical issues raised by post hoc analysis and data
snooping
b the different multiple comparison methods commonly used by researchers to test
for differences among cell means and
c the advantages and disadvantages of each method
Note Your written description will be evaluated based on your demonstrated
competence with the statistical method not on the pedagogy of your explanation
F) Applied Data Analysis
16) Q Your departmental chair is considering a new textbook and has asked for your
recommendations You conduct a well-designed controlled study (details are unimportant) and discover students who use the new book perform 10 better on a standardized subject
matter exam than those using the old book (p = 027) Both books are readily availabe their prices are almost identical and both are equally acceptable to the instructors What is your recommendation to the chair
F1 Attached is the beginning of an article Your task is to write the results section by
1 making up and reporting plausible descriptive statistics that will help the
reader understand the results of the statistical tests you report and the nature of your
sample (Hint this can be presented in the form of a table)
2 describing and defending your choice of appropriate statistical tests of the
hypotheses and the steps that you would go through in carrying out these tests
3 making up and reporting results of these tests that are consistent with your
descriptive statistics and with any information in the rest of the article about the
results found (Hint this can be presented in the form of a table)
4 describing how well these results provide support for the hypotheses You
may want to note any relevant threats to validity here
Be sure to state any assumptions you make
F2 Assume that the Personnel Manager of a local firm Ms B dFlandres hired you to
analyze some data that her assistants had collected over the past several years The
data consist of (a) job performance ratings that were made in June of 1990 and (b)
scores on 25 predictor variables (eg measures of education job experience job
tenure job aptitude personality) that were measured when the individuals were hired
(between April 1987 and May 1988) She had data from only the 110 subjects (60
males and 50 females) who were hired during the period and were still employed by
the firm One objective of your analysis (analyses) is to determine how well the
performance criterion can be predicted by the predictors What strategy would you
use in analyzing the data Describeexplain (b) Is sample size an issue for your
analyses Explain If it is what will you do to deal with problems stemming from
sample size Assume that no additional data can be collected at this time (c) Some
preliminary analyses that you do reveal that five of the predictor variables correlate
(zero-order basis) about 75 with one another Will this influence the analyses that
you use Will it influence the validity of conclusions derived from your proposed
analyses (d) Ms dFlandres is interested in knowing if the predictor variables are
equally effective in predicting the job success of males and females What analysis
or analyses would you do to deal with this issue
F3 Assume that you have been provided with data on 12 conceptually distinct variables
that are moderately correlated with one another at the empirical level The data are
from students in four different college majors ie astronomy (A) biology (B)
criminology (C) and demography (D) The 12 measured variables fall into the
general categories of mental health (tension emotional withdrawal hallucinations
guilt feelings blunted affect and suspiciousness) and job satisfaction (work itself
supervision co-workers pay promotion prospects and working conditions) Your
task is to determine if the individuals in the four college majors differ from one
another on the 12 measured variables
(a) What statistical technique(s) would you use to test for group differences
Explain Be specific about the procedures(s) that you would use
(b) What statistical estimate would you use to estimate the extent to which the
groups differ from one another Be specific
F4 The following statistical table published in a recent issue of Work amp Occupations
was taken from an article discussing variables influencing resistance and citizenship
behaviors in the workplace Resistance behaviors include playing dumb withholding
effort work avoidance subverting particular managers and sabotage Citizenship
behaviors include cooperation engaging in peer training use of insider knowledge to
facilitate production commitment to organizational goals giving extra effort freely
Both measures are global constructs aggregated to the interval level and
standardized
The table reports the results of a series of ordinary least squares regression equations
with standardized coefficients Explain the meaning of the statistics presented What
do these statistics tell us generally about the relationship between resistance
behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows
Anomie Index -standardized interval level measure tapping multiple dimensions
The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)
F5 Researchers collected data from a sample of 350 companies on the following
variables
size (measured as number of employees)
Business Strategy (a nominal variable with 2 response options low-cost provider or
differentiator)
HR Strategy (a nominal variable with 2 response categories High commitment or
low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

I2 A study examined the effects of gender and pre-training motivation on the transfer of
training in terms of improved performance for 123 new industrial managers The
training was on supervisory skills and the dependent variable was based on the

mirrors Explain both sides of the debate and then lay out the role of meta-analysis
as you see it within the time span of your career as an academic To do this use
examples of already written (or yet to be written) articles as models
J5 A frequent criticism of non-quantitative research summaries (literature reviews) is

affected the statistical outcomes of the studies included in the literature review Meta-
analysis however allows one to statistically examine such effects Assume you are
conducting a meta-analysis of the relationship between leader behaviors and group
productivity Briefly describe the steps you would take in conducting a meta-

and discuss the assumptions of the general linear model Multiple regression
ANOVA and principle components (factor) analysis are based on the general linear
model For each of those three statistical procedures describe and discuss the
following
a The type of data necessary for using the technique appropriately

O1 Contrast Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis
(CFA) Give an example for the appropriate use of each of the above analyses
What is the role of theory in the two factor analyses
IC

assumptions usage and limitations
O3 How do exploratory and confirmatory factor analysis differ What are the
advantages and disadvantages of each
O4 Describe the differences between exploratory factor analysis (EFA) and
confirmatory factor analysis (CFA) When would you use one verses another
Are there ways to use EFA in a confirmatory way Can you use CFA in an
exploratory way Also describe the difference in principal components analysis
(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression

information in each matrix and its purpose
(2) For what purpose do researchers use factor analysis Explain In the process
provide a very brief description of a study for which factor analysis would be a
useful data analytic technique

c the type of quantitative output that results from applying the technique
d how a researcher would use the output in his or her research

f the important issues and problems in using the technique
P) Structural Equation Models
P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)
Please comment on these restrictions versus access argument Which side do you
take
What are the strengths of SEM Give some examples
What are the weaknesses of SEM Give some examples

the participants and generalizability of the findings to other elements of a chosen
population D) Finally discuss advantages if any of using laboratory and field
survey methods in tandem
G) Experimental Design
2) A colleague suggests to you that only true experiments can provide useful results in
science Why might she say this What would you offer as a defense for the role of quasi-
experimental and non experimental designs in the context of the social science In
answering this question make sure you identify the defining characteristics of each design
type
9) Why and when should we be concerned about non response in research What are the
things we can do to try and decrease non response (or increase response rates)
11) Why might a researcher choose to utilize an experimental design that incorporates pretest
measure on the DV
G1 Experimental designs oftentimes come under attack due to perceived limitations in
external validity (a) Relative to other design types what strengths and weaknesses
do they offer (b) What experimental design structure is the strongest Why (c)
What is the relevance of research design for results and theory development
G2 Meta-analysts often investigate whether the quality of research design (eg
randomized experiments vs non-randomized designs) influences average effect
size In their meta-meta analysis of psychological educational and behavioral
treatments Lipsey and Wilson (1993) found that In a given treatment area poor
design or low methodological quality may result in a treatment estimate quite
discrepant from what a better quality design would yield but it is almost as likely
to be an underestimate as an overestimate (p1193) A few methodologists (eg
Shadish) have attempted to identify factors that may explain the relative magnitude
of effect sizes from randomized and nonrandomized experiments Please review
these findings and add your tentative model of the conditions under which random
experiments will produce larger smaller or equal effect sizes relative to
nonrandom designs Discuss possible implications for research design in the
context of real-world interventions
G3 Analysis of covariance and randomized blocks designs are sometimes referred to as
noise-blocking designs Explain what this means and give an example of (a) a
randomized blocks experiment and (b) an analysis of covariance experiment Keep
your examples simple Describe how such designs are noise-blocking when used
with randomized assignment of subjects to experimental condition and contrast
that with the role such designs serve in quasi-experimental designs
G4 Team performance in Bafko Industries varies considerably across teams and from
month to month The senior VP in charge of team development thought that a team
training program could improve the performance of these teams A consultant
convinced him that his firms training program which lasted only one week and
cost only $25000 per team) could raise the performance of Bafkos teams The VP
however wanted to experimentally test the efficacy of this training program before
he adopted it widely throughout the firm So the consultant suggested the following
experimental test
There were 48 teams in Bafko that showed significant variation from month to
month in their level of performance The consultant chose the 24 worst performing
teams based on last months data and assigned them to the training group After
all he argued these were the ones who most needed it The other teams were
assigned to the control group The training group received the training program
(lasting one week) at the beginning of the next month while the control group
teams did their normal routine Performance scores were gathered at the end of the
month The results showed that the training group teams had a significantly larger
rise (ie statistically significant) in their performance than did the control group
teams (who as a group did not improve at all) The consultant proudly displayed
these results and argued that they convincingly demonstrated the efficacy of his
program
How would you advise the VP Specifically what is the validity of the consultants
conclusions If you think he might be mistaken what specific threats to internal
validity are particularly plausible
G5 Consider the following design
N O Xa O
N O Xb O
N O Xc O
N O O where
Xa Xb and Xc represent different levels of a training program that varied in its
length across three different work groups In group a the training time was 40
hours in group b it was 30 hours and in state c it was 20 hours The training was
designed to instill customer service values in the team members O represents a
measure of customer service attitudes measured with a 20-item Likert scale This
measure was administered one week before the training program and 3 months
later The researcher hypothesized that the training program would improve
customer service attitudes and that longer training would have stronger effects
The design is a non-equivalent groups design because people were not randomly
assigned to groups even though groups were randomly assigned to treatment
condition Each group has a sample size of 36 members The reliability of the
customer service attitude scale was 78 at the pretest and 80 at the posttest The
pretest means were as follows
Group A 26
Group B 23
Group C 27
Control Group 25
a Construct a regression model that will test the researchers hypothesis Be
explicit here describing each variable in the model and what regression effect(s)
you would expect to find if the hypothesis were correct (Hint everything you need
to know is in Trochims chapter 11 and what we discussed in class) (10 points)
b Describe any serious threats to internal validity (10 points)
c Discuss how you might amend this design to improve its internal validity(10
points)
G6 Often in organizational research the researcher is faced with having only one group
on which to experiment and thus cannot use a control group when conducting
experiments This occurs for example in taxation experiments when you cannot
selectively apply new tax laws to different groups or when you wish to test the
efficacy of an incentive plan that must be applied to all members of a company In
such situations the researcher must be creative in assembling a quasi-experimental
design that has high validity (and usually the challenge concerns internal validity)
Consider the following scenario
A manager of a retail store wants to test the efficacy of an incentive program in
changing the selling behaviors of her retail sales clerks Specifically she wants to
test a behavioral reinforcement program in which sales peoples behavior is
recorded on in-store video cameras The tapes are analyzed each night and the
experimenter tabulates the frequency of various behaviors (eg offering assistance
to customers restocking items straightening up displays suggesting accessory
items to accompany the items that a customer is purchasing) The manager then
rewards the clerks with a monetary bonus based on the frequency of desired
behaviors She would like to conduct a valid experiment to see what effect such an
incentive program has on employee behavior but because of concerns about
employee morale she cannot assign clerks to treatment and control groups Instead
she has to apply the experimental treatment to everyone in the store She learned in
her research methods class (which the company requires all its managers to take)
that a single group experimental design typically has very low internal validity
Your job as a consultant is to help her design an experiment given her constraints
that would produce interpretable (ie internally valid) results Describe the details
of the design you would recommend using the notation in Trochim (2001) If the
design you come up with has a specific name use it As part of describing your
design discuss how the data would be analyzed and what particular effect you
would look for
G7 Why are experimental research designs held in such high regard
G8 Compare and contrast experimental quasi-experimental and correlational research
designs What characteristics separate these three designs What are their
advantages and disadvantages especially in comparison to one another
G9 What is the difference between a within-subjects experimental design and a
between-subjects experimental design When might a within-subjects design be
appropriate When might it be inappropriate
G10 Describe the difference between a basic within subjects and between subjects
experimental design What are the advantages and disadvantages of each
especially in comparison to one another Give an example from your area of
research in which each would be appropriate
G11 What are the major threats to the internal validity of a pretest - post test
nonequivalent control group design How can this design be improved with regard
to increasing a researchers ability to make causal inferences
G12 A production manager is interested in testing the hypotheses that participation in
quality circle programs will result in increased productivity and reduced
absenteeism A questionnaire is administered to a group of 92 employees
concerning their attitudes toward such programs and 46 with the most favorable
attitudes who are willing to participate are selected for the treatment group The
remaining 46 are the control group Measures of performance (unitsmonth for the
group) and absenteeism (lost daysmonth for the group) are kept over a three month
period during which the treatment group has weekly quality circle meetings The
results are as follows
Month 1 Month 2 Month 3 Month 1 Month 2 Month 3
Performance Absenteeism
Treatment 100 115 121 6 9 4
Control 110 108 113 6 8 5
The manager calculates t tests between month 1 and 3 The only significant
difference is performance for the treatment group so the manager concludes that
quality circles raise productivity but do not have an effect on absenteeism What
are the primary threats to internal and external validity in this study What are
possible alternative explanations for the differences (or lack of differences)
between the two groups What additional information might help explain these
results
G13 One stream of current strategy research contains event studies In these studies
investigators basically correlate the reaction of a financial market to the presence
andor absence of the occurrence of some event at a firm (eg the resignation of a
CEO) In a different approach to such a study suppose that one investigator (Jean)
conducts a natural field experiment on the effects of competitor mergers on a
firms environmental scanning activity Through previous arrangement Jean has
been working with 5 medium-sized computer hardware and 5 medium- sized
software firms on the west coast Shes been collecting a paper trail of internal
memos reports and phone calls that might measure environmental scanning
activity Shes been finding that the firms in both industries do about the same
amount of scanning (no significant differences) However in the midst of her data
collection Norton announces a merger with Symantec (software) A year later
Jean compares the amount of post-merger environmental scanning in the software
industry with that in hardware industry Just as Jean had hypothesized a t-test
shows a greater amount of post-merger scanning among the software firms She
concludes that her hypothesis was supported mergers of competitors cause an
increase in scanning
Critique the study described above in terms of its design flaws Identify the design
Jean used Briefly allude to problems the study has with external validity but
concentrate on the Cook and Campbell threats to internal validity Provide a
rationale for why each threat is or isnt operating in the study Link each of the
relevant threats to the specific constructs being studied (mergers and environmental
scanning) Finally do a summary evaluation -- what can be learned from this
study
H) Quasi-Experimental Design
H1 The University of Mississippi observed that the graduation rate of students with poor
grades during their freshman year was much lower than those with better grades
Wanting to improve the chances of these low performing students they tested the
effects of a new rule for freshmen The rule stated the following At the end of their
first semester all students with a GPA between 200 and 225 must register for
EDUC 1003 during their second semester Students with a GPA lower than 200
were put on academic probation EDUC 1003 consisted of a course whose objective
was to help students develop good study skills The theory was that poor study skills
were a significant cause of poor academic performance and that study skills could
be learned
They wanted to evaluate the effectiveness of this intervention so they collected data
on the GPAs of students beginning with their first semester and continuing through
to their third semester At that point they wanted to analyze the data to determine
whether the new rule was making a significant difference in the students academic
performance
What is the best way to analyze these data to reach an interpretable conclusion
Describe your approach and then discuss the major threats to validity that it has
Their sample size of students was as follows
Total N= 3454 (these are students who completed all 3 semesters)
Number of students with first semester grades between 200 and 225 (and thus took
EDUC 1003) was 956
H2 A nationwide furniture company wants to determine if a diversity training
program will improve individual sales performance on the floors of its urban retail
outlets A group of 45 salespeople in one city were given two weeks of training
Measures of individual sales performance were taken once two months prior to the
program and once two months after Forty-five salespeople (who did not receive the
training) in a similar city had the same measures taken at approximately the same
points in time The training group increased their average weekly sales from $14000
to $16500 while the non-training group improved theirs from $13000 to $14500
The change for the training group is statistically significant the change for the non-
training group is not
How would the interpretation of these results in this quasi-experimental design
differ from a true experimental design What are the threats to internal validity in
the above study and how might they be operating (be specific) What additional
information and analyses would be useful in controlling for these threats
H3 An accounting firm is interested in determining if a re-training program will reduce
errors made by its audit teams A group of 45 auditors in the home office location
are given two weeks of re-training Measures of the frequency of detectable errors
are taken once two months prior to the program and once two months after Forty-
five auditors in similar office at a branch location have similar measures taken at
approximately the same points in time The training group reduced their average
number of errors per audit from 8 to 3 while the non-training group reduced theirs
from 11 to 9 The change for the training group is statistically significant the change
for the non-training group is not
How would the interpretation of these results in this quasi-experimental design
differ from a true experimental design What are the threats to internal validity in
the above study and how might they be operating (be specific) What additional
information and analyses would be useful in controlling for these threats
H4 Describe the main classes of threats to validity that are found in quasi-experimental
research designs
H5 Dr Delta an organizational development consultant was hired by a firm that has
600 pizza parlors nationwide to assist in implementing organizational changes that
he hopes will result in higher levels of job involvement At the outset of the study
subjects had jobs with very low levels of enrichment and were paid on an hourly
basis He designed an experiment in which stores were randomly assigned to one of
three treatment conditions Condition 1 subjects experienced job enrichment (JE)
and a change to performance-based pay (PBP) Condition 2 subjects experienced
only JE and Condition 3 subjects experienced only PBP The parlors were
sufficiently far apart from one another and communication among the parlors so
poor that subjects in any parlor were totally unaware of changes made in other
parlors At the end of 18 months he measured the job involvement levels of workers
and then tested for differences between the three conditions using a standard one-
way analysis of variance In view of Dr Deltas design answer the following
questions
How sound is Dr Deltas design Comment on the weaknesses of the design
I) Interrupted Time Series Design
I1 What threats to internal validity are and are not ruled out by an interrupted time series
design that includes the introduction of a treatment and its removal at a subsequent
time period List and explain In the process be certain that you provide a diagram
that illustrates such a design
J) Validity Some Questions are about the validity of a measure others about experimental validity)
10) Identify four threats to internal validity and briefly describe what they mean
J1 It was some time ago that the tripartite view of validity was abandoned in favor of a
unitarian view in which different evidentiary bases for validity might be put forward
Binning amp Barrett (1989) represent an attempt to place multiple evidentiary bases into a
single framework Cook amp Campbell (1979) describe four aspects of validity but they
arent really meant to represent evidentiary bases Adding to the confusion is the fact
that while Binning amp Barrett and Cook amp Campbell use some of the same terms these
two pairs of authors clearly mean different things by these terms and intend for them to
be used in different ways Your task is to 1) Describe the evidentiary bases discussed
by Binning amp Barrett 2) Describe the aspects of validity described by Cook amp
Campbell 3) Describe the similarities and differences between the two lists including
the different purposes served by the two lists and 4) Present a single framework that
incorporates both This last task is the most important of the four
J2 What are the types of validity How would each affect an empirical study IC
J3 Define both internal and external validity Which is more important (it is not okay to
say that they are equally important) Defend your reasoning
J4 Why might someone argue that the construct validity of a measure can never really be
established
J5 Describe each of the following forms of validity content convergent discriminant
criterion-related and construct How is each assessed How do they related to each
other Which is most important (Make sure you defend your answer)
J6 Define and explain 6 of the 8 types of validity listed below and describe the type(s) of
information each provides Choose one specific type of study as an example (eg
cross-sectional study experiment quasi-experiment simulation ethnography etc) and
compare and contrast the usefulness and importance of each type of validity for that
type of study
-- Concurrent validity
-- Construct validity
-- Content validity
-- Convergent validity
-- Discriminant validity
-- Statistical conclusion validity
-- Internal validity
-- External validity
J7 Designing empirical research has been called making a series of trade-offs
Unfortunately decisions that are made to increase one desired quality (like internal
validity) can also decrease another desired quality (like external validity) For each of
the issues below discuss the concerns involved (ie the trade-off) and identify the
qualities that are being increased or decreased
a laboratory vs field study
b using a 5-item measure vs a 1-item measure
c using a student sample vs a sample of full-time employees
d using a sample of employees from one company of 5000 vs 500 employees from
each of 10 companies
e collecting your data using one method vs collecting your data using multiple
methods
J8 There are four major types of validity in social science internal validity external
validity construct validity and statistical conclusion validity Please address the
following three issues concerning validity
a What is the meaning of the four major forms of validity (ie internal and external
validity construct validity statistical conclusion validity)
b Are there trade-offs that can or must be made among the four types of validity
d Describe how the concept of validity varies across the research traditions of
experimental vs observational research
IC
J9 The quality of research is often assessed by examining validity issues As you are
aware there are numerous typesforms of validity (eg internal and external validity
construct validity statistical conclusion validity) These types of validity address
different aspects of the research process For this question please address the following
issues
a What is the meaning of the four major forms of validity (ie internal and external
validity construct validity statistical conclusion validity)
b Should there be a priority among these forms of validity If yes why If no why not
c Does the concept of validity vary across research traditions (ie experimental vs
observational research) If yes why If no why not
J10 External validity has received considerable attention in the social and behavioral
sciences Some researchers argue we are too concerned with the external validity of our
findings while other researchers argue that we are too unconcerned with external
validity Several points of view have been developed to explain what is external
validity When answering this question please be sure to address at least the following
issues
a Compare and contrast alternative conceptualizations of external validity
b Some researchers have argued that the role of external validity is invariant across
research traditions (ie experimental vs observational research) Defend the
perspective that the role external validity is invariant across these two research
traditions In addition present the weaknesses of this perspective
J11 In designing a research study researchers must consider trade-offs between internal and
external validity Explain what is meant by internal validity and external validity What
is the nature of these trade-offs How would you evaluatedetermine which is more
important internal or external validity for a particular study Why is this such an
important issue in organizational studies
J12 A researcher conducted a quasi-experiment to test the effects of participative decision
making (PDM) on job attitudes of employees Employees from different departments in
a large organization were assigned to either a treatment group (PDM implemented) or a
control group (no PDM) Random assignment was not possible because of work
schedules coordination of tasks etc Thus the design can be considered an untreated
control group design with pretest and posttest and is represented as follows (where
O=observation X = treatment)
________________
O1 X O2
-------------------------
O1 O2
_________________
The results of the experiment are presented in the graph below [no graph provided]
The dependent variable is job satisfaction and is measured on a 100 point scale (with
100 being extremely satisfied) How amenable are these results to causal interpretation
What is (are) the major threat(s) to internal validity B if any B for this type of design
given these results What steps can be taken to assess the extent of this (these)
threat(s)
K) Data Collection Methods
14) Describe the various methods of data collection (eg survey interview observation etc)
available to a social scientist What are the advantages and disadvantages of each relative to
each other
K1 Within micro organizational research much criticism has been raised concerning
the reliance on self-report survey data What potential problems does self-report
survey research raise How big of a problem do you think this is
K2 There are a number of methods for collecting data (eg survey interview archival
etc) that are available to a social scientistorganizational researcher Discuss each in
terms of their strengths and weaknesses both on their own and in comparison to one
another
K3 Pick an important construct in your favorite area of management research for which
there is some controversy about how it should be measured or operationalized (eg
environmental munificence or growth need strength) Give the prevailing verbal
definition of the construct and analyze the measurement controversy from two
broad angles First discuss how the controversy may or may not stem from claims
about how one measure is better or worse than another because it (or the other) is an
(a) archival record (b) direct observation (c) social report or (d) self-report That is
what are the relative strengths and weaknesses of each of these types of
measurement for the construct youre discussing Second discuss the construct
validity of the most commonly used measure(s) of this construct To answer this
second part you need to discuss just what construct validity is and how it can or
cannot be demonstrated In the situation you describe what could be done to
demonstrate or improve the construct validity of existing measures
K4 Interviewing in some form has been the workhorse for data collection in a variety
of research traditions positivistquantitative ethnographic feministpost-modernist
and increasingly historical research While each tradition elicits information from
respondents the goals and processes involved in interviewing vary considerably
across research traditions Discuss the purposes of the interview the relationship
between data and theory the roles assumed by the interviewer and the respondent
and the relevant criteria for assessing the validity and reliability of the information
obtained In addition compare and contrast the use of the interview as a data
collection method in the positivistquantitative tradition with its use in one of the
alternative traditions
L) Common Method Variance
L1 Many of us have had concerns about the reviews of our survey research which
suggest that data analyses of surveys are biased because of common method
variance effects of individual differences such as negative mood negative
affectivity and social desirability and the reliability and validity of the constructs
we are attempting to measure Define how these problems affect a research issue in
organizational behavior and the steps that might be taken to minimize such potential
criticisms of papers based on analyses of self-reported data through survey
instruments
L2 In a series of papers by Spector (1994) Schmitt (1994) and Howard (1994)
published in the Journal of Organizational Behavior arguments were provided for
and against the use of self-report questionnaire measures One of the issues
discussed that could limit conclusions drawn from relationships observed using self-
report measures was method variance What is meant by method variance what are
its sources and what impact is it expected to have on research findings
M) Sampling
M1 The manufacturing census samples all plants of 250 employees or more For
plants of 5-249 employees it takes a size proportional sample Plants of 1-4
employees are not sampled What challenges does this sampling method provide
to researchers What could you do to account for these problems if you were
TH
studying organizational (not plant) growth
M2 New York State has approximately 250000 employees in over 70 state agencies
commissions and boards ranging in size from approximately 50 to over 5000
employees Assume that you wanted to draw a representative sample of 1000
employees Describe two ways that you could draw such a sample and briefly
describe the advantages and disadvantages of each of these sampling approaches
IC
M3 The director of a national non-profit agency with approximately 10000
employees located primarily in regional offices in each of the 50 states the
United States has approached you and asked you to develop a study
(organizational survey) of organizational culture within the agency The agency
is about to embark on a variety of change initiatives including developing team
structures and the study is meant to examine various elements of organizational
culture that are potential barriers to change The director has indicated that he
would like to have the data analyzed at both the individual and office level of
analysis Because of funding limitations the agency will only be able to send the
survey to 1000 employees The director has indicated that there are three ways
of sorting employees all employees listed alphabetically all employees listed
alphabetically by state and all employees listed alphabetically by region (there
are between five and ten regions per state) Given these three ways of sorting
employees describe at least three different sampling approaches and the
advantages and disadvantages of each
M4 In your role as Teacher of Organizational Studies you are asked to prepare a
tutorial for beginning doctoral students on sampling design Assume that this
tutorial is part of a basic class in research design and that students in this class
have had a basic statistics course up to and including multiple regression Your
tutorial should focus on briefly defining and explaining the differences between
probability and non-probability samples You should make sure to present and
describe several types of probability samples (eg random systematic
stratified etc) and non-probability samples (eg convenience snow-ball quota
etc) and discuss general principles for when to use a probability vs a non-
probability sampling design For each sampling design you should also provide
at least one clear example of a situation where this type of sampling design is
appropriate
N) Cross-Cultural Research
N1 Discuss the problems in conducting cross-culturalnational comparison in terms
of (1) conceptualization and (2) research design and data collection
Define the three levels of measurement invariance How would the problems that
you have identified in part (a) affect measurement invariance How would you
examine measurement invariance by confirmatory factor analysis
TH
N2 Explain why using national boundaries as independent variable in cross-cultural
studies may not be appropriate in terms of theory and research methods What
alternative ways would you recommend
IC
O) General
O1 In your readings research has been described as choices among conflicting goals
(desiderata) For instance when choosing among research strategies a researcher
must choose among the desiderata of precision realism and generalizability The
trade-offs among desiderata occur for all aspects of research that is for the selection
of theories the treatment of independent variables research strategies the selection
of the problem to study rules of evidence for determining the meaningfulness of a
research finding and even the frameworks that describe the research process
Discuss what you see as the major trade-offs for each of the following aspects of
research That is discuss what you see as the major strengths and weaknesses
(advantages and disadvantages) of each aspect
a The trade-offs between internal and external validity
b The manipulation of the independent variable vs the observation of the
independent variable
c Basic vs applied research
3 DESIGNING A RESEARCH STUDY
A) General (Research Design)
3) Why is control so important in research design What are the different ways it can be
achieved (give a brief description of each control method) What are advantages and
disadvantages of each
A1 It has become almost a truism to note that the choice of methods influences theory
and questions data and conclusions (the causal direction might also be reversed)
Briefly discuss how the methods used have influenced research in any two of the
following areas leadership power and politics organization culture organization
justice Compare and contrast as possible Suggest some potentially fruitful
methodological directions for future work in these same topical areas and dont be
shy about reflecting on broader issues of how the field of organizational behavior
constructs its realities Lastly tie your discussion and reflections back to your own
future as a researcher what lessons or guidance do you derive from your
understanding of these issues
A2 Characterize as fully as possible what you see to be the methodological approach or
approaches in strategic management research Is there a dominant method or a wide
variety Discuss the reasons for the situation What are the advantages benefits etc
of the approach(es) in use What assumptions (ontological epistemological
ideological) do they embody Are current efforts ideal or at least adequate Are
there other approaches that could be useful If so how might researchers be
encouraged to use these as well If you see no advantage to more variety in
methodological approach support that point of view
A3 Describe a research question or area of interest to you and why you think it is not
only of interest but significance Using your understanding of research methodology
describe two ways of pursing the question that are as divergent on as many
dimensions as you can imagine Describe the advantages and disadvantages of each
approach How strong a link or fit is there between a research question and a
method
A4 In his 1957 article entitled The two disciplines of scientific psychology Cronbach
discussed the assumptions goals and methods used in experimental methods and
correlational methods in psychology
a According to Cronbach what is the main difference between the two disciplines
b Discuss the strength and weaknesses of each discipline
c What if anything could be done to improve the situation
B) Designing a Research Study
B1 Cook and Campbell describe the experiment as the research design with the
greatest methodological rigor However given the constraints present in most
organizations I-O Psychologists cannot often conduct experiments in applied
settings and must settle for techniques with less control than experiments
Describe a study to investigate the relationship between participation in a
supervisor training program and work performance which could realistically be
conducted in an organization If an experiment is not possible describe how you
would go about maximizing your ability to draw valid conclusions from your
design
B2 The XYZ Co has recently developed a sexual harassment web-based training
program The developers claim the program will cut training time and costs and
will be as effective or more effective than classroom-based sessions They
believe that this will be due to the increased availability of the program and the
ability for participants to review program material on demand Before the XYZ
Co developers launch this product they want you to determine if their claims
have merit Explain how you would design a study for this purpose
B3 Research suggests that demographic diversity improves group creativity but
reduces group efficiency Some argue that demographic diversity is just a proxy
for value and experience diversity and that demographic diversity on its own is
meaningless Design a test to settle this argument
TH
B4 E-mail has become a common form of communication in organizations and is
used for both formal and informal communication Because it has become so
IC
popular some people complain that the frequent use of e-mail leads to
miscommunication because they receive communications in e-mail that should
be accomplished through face-to-face or telephone conversations where there is
an opportunity for interaction You are interested in looking at this
phenomenon You are most interested in describing how e-mail is used for both
formal and informal communication and in examining the effect of the e-mail
use on organizational communication effectiveness Design empirical research
to address those issues
Describe your study in detail thoroughly explaining the research design
sampling plan data collection procedures ethical issues and proposed data
analysis for your research design Be sure to discuss the internal and external
validity of your research Which validity threats are ruled out and which
remain
REMEMBER Be thorough Your research design should demonstrate that you
are a competent researcher who is knowledgeable about the proposed research
methodology or methodologies Therefore be sure that you carefully describe
and give technical explanations for each component of your research
B5 Choose a specific situation involving employee selection eg artists for an
advertising agency (a) What strategy would you use in selecting the selection
measures (b) How would you combine the measures eg which measures
would you combine in a compensatory manner and which is a noncompensatory
manner (c) How would you assume test fairness defining various measures of
the term (d) How would you make final selections (e) How would you
validate your procedure (f) What considerations would enter in if your
company were too small to provide validation data (g) What difference would
it make if you were developing a procedure for deciding whether trainees
should be promoted as opposed to making new hires Please note--emphasize
but do not limit yourself to statistical issues
B6 There is evidence in the marketing literature of a non-monotonic relationship
between the expectations that customers have for retail service and their
eventual level of satisfaction with that service That is as a customers
expectations for service increase so does their eventual service satisfaction --
up to a point After that point the greater the expectations the lower the
eventual satisfaction Develop a hypothesis that includes a moderator variable
that might account for this evidence Give some reasonable rationale for it State
your hypothesis verbally as an equation as a directed graph (circle amp arrow
diagram) and as an X-Y function chart Discuss how it would or would not be
possible or useful to test your hypothesis via a laboratory experiment In your
discussion cover how and why a researcher could (not) manipulate the
independent constructs involved (mode X) whether or not random assignment
to conditions (mode R) is possible (including how may conditions would be
necessary) which alternative constructs could or could not be controlled (mode
K) and which constructs should be measured (mode Y)
B7 Assume you are the chairperson of a committee that must evaluate
undergraduate programs at your university Your task as chairperson is to
devise an approach (a design a research strategy a set of measures) that will
allow you to evaluate undergraduate programs Make sure that your approach
can be used in the future and at other comparable universities When developing
your plan be sure to address at least the following issues
a the type of design you would select Compare and contrast the selected design
with another possible design
b the type of research strategy you would select Compare and contrast with
another possible strategies
c discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
B8 Assume you are an organizational research design expert assigned to the
Strategic Planning Department of a large multi-national manufacturing firm
The Department has developed a new PC-based software package called
STRATPACK The software (and a one-week training course to learn how to
use it) is intended to improve the long-range planning ability of middle and
upper-level managers
Your job as research design expert is to devise research (a design a research
strategy a set of measures) that will allow you to evaluate the effectiveness of
the STRATPACK program Describe a research design for evaluating the
program Make sure that your research approach can be used in the future and at
all sites in the company When developing your plan be sure to address at least
the following issues
a discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
b the type of design you would select (eg a design where you manipulate the
independent variable versus observe the independent variable) Compare and
contrast the selected design with another possible design
c how your design deals with the major forms of validity Be sure to examine at
least internal external and construct validity
B9 Assume you are a consultant hired to evaluate the effectiveness of an industrial
safety program undertaken by a large manufacturing organization The safety
program is a behavioral one that provides rewards such as monetary bonuses or
extra paid vacation days for safety behaviors in terms of accident-free days
weeks etc Your task is to devise an approach (a research strategy a design a
set of measures and a general analysis strategy) that will allow you to evaluate
the safety program Because of the potential for the influence of many
extraneous variables on any safety program it is difficult to design research a
single cross-sectional study than can evaluate the impact of a single safety
program How would you design a study to evaluate the impact of the safety
program When developing your plan be sure to address at least the following
issues
a the type of research strategy you would select Compare and contrast with
another possible strategies
b the type of design you would select Compare and contrast the selected design
with another possible design
c discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
B10 One of the most important areas of research is forecasting of human resources
needs based on strategic positions of organizations For example NY State must
carefully forecast its human resources needs as it proceeds with significant lay-
offs of state employees Future human resources needs are generally evaluated
by either statistical ie regression or simulation or clinical judgment i e
supervisors judgments methods
a Design a single study that addresses the empirical question of whether
statistical or judgmental methods are better for forecasting human resources
needs You may discuss a program of research but please be quite specific in
your description of the first study
b What are the critical methodological issues in doing this kind of research
c What are the critical applied (or practical) issues in doing this research
d Are the issues in b and c related
B11 In the past decade computinginformation technology has changed many
aspects of organizational life For example the technology can make increased
decentralization possible by improving communication between central offices
and field offices Computer networks and word processors can enhance group
empowerment by making it possible for team members to create and edit
written group products quickly even if the individuals are at different locations
Some have argued that computinginformation technology will foster the
paperless productive office nevertheless others argue that the technology only
increases paper and reduces office productivity You are applying to the
National Science Foundation for a grant to conduct research that examines the
impact of computing information technology on organizational decision
processes The NSF application procedure imposes five basic requirements that
your research design must fulfill in order to receive funding Note A very
significant factor affecting NSF grant decisions is a clear demonstration that the
researcher is knowledgeable about the research methodology used Write your
response to each of the following five grant requirements Be sure not only to
respond to the requirement but also to demonstrate your research
competence
1You must design a study that uses two different methods
(interviewobservation survey experiment or quasi-experiment) Describe your
two methods in detail and provide a rationale for the key elements (eg
sampling data collection proposed analysis) of your methods Be sure to
discuss and evaluate the internal and external validity of both methods
2 As part of your research design you must select a conceptual (latent) variable
central to your proposal (use centralization of decision making as your
variable) and describe how you will develop your own measure (You may not
simply use off the shelf instruments)
3 You must describe how you will test for the reliability of the measure
(centralization of decision making) you developed in step 2 The NSF insists
that you describe how you will evaluate both the temporal stability and the
internal consistency of your measure Be sure to discuss what temporal stability
and internal reliability mean and how they are related
4You must describe how you will assess the validity of the measure
(centralization of decision making) you developed in step 2
5 NSF requires a brief statement and defense of the philosophy of science
underlying your research Discuss your position and show how your research
design is consistent with your philosophy
B12 Many organizations in the United States economy have installed some form of
Empowered Teams as an alternative or supplement to traditional bureaucratic
structure Preliminary evidence of the effectiveness of empowered teams
however is mixed--some organizations have claimed success and others have
reported failures The evidence however is predominantly anecdotal--written
for trade magazines by the organizations themselves There are few rigorous
empirical studies assessing the effectiveness of empowered or self-managed
teams You are applying to the United States Department of Labor (USDOL) for
a grant to conduct research that examines the effectiveness of empowered
teams The application procedure of the USDOL imposes three requirements
that your research design must fulfill in order to receive funding Write your
response to each of the three grant requirements The importance of each section
is implied by the evaluation points allocated by the USDOL to each of the three
requirements given in parentheses
1 (50 points) Your study design for assessing Empowered Team effectiveness
must use two different methods (interview observation archival analysis
survey simulation experiment or quasi-experiment) Describe in detail and
thoroughly explain the sampling plan instrumentation data collection
procedures and proposed data analyses for both methods Be sure to discuss the
internal and external validity of both methods and how the two methods
complement one another
2 (30 points) As part of your research design you must select one conceptual
(latent) variable central to your proposal and describe how you will develop
your own operationalization of the measure (You may not simply use off the
shelf instruments) Use the concept of group morale to demonstrate your
operationalization methodology Be sure to explain very explicitly to the
USDOL how you will assess the validity and reliability of the group morale
measure you are developing
3 (20 points) The USDOL traditionally has funded research conducted only
within the general paradigm of logical positivism but now is more open to other
research paradigms as well Your grant proposal must provide a statement and
defense of the explicit philosophy of science underlying your research Describe
your philosophy of science and show how your research design is consistent
with your philosophy
REMEMBER Be thorough You not only must design effective research but
you also must demonstrate to the USDOL that you are a competent researcher
It is absolutely vital to the USDOL that the principal researcher is
knowledgeable about the proposed research methodologies Therefore be sure
that you always carefully describe and give technical explanations for each
component of your research design and explain all technical terms (eg
Cronbach alpha KR-20 Likert scale)
B13 Assume that you are working as part of a research team that is responding to a
RFP (Request for Proposals) from a funding agency for research on work
socialization and newcomer adjustment The RFP calls for rigorous field
research that tests the effectiveness of theory-based interventions aimed at
facilitating the adjustment of new organizational members to complex andor
stressful work conditions The major goal of your teams research is to test the
effectiveness of a self-regulation intervention which trains newcomers to
identify and use relevant social information and cues to regulate work behavior
Your group hypothesizes that self-regulation training will be more effective
than other common treatments or interventions (eg realistic job previews
institutionalized socialization tactics)
You have been included in the team because of your methodological expertise
Your role is to design a rigorous field experiment or quasi-experiment to test he
effectiveness of the self-regulation training program REMEMBER THE
MAJOR CRITERION FOR FUNDING IS THE RIGOR OF THE RESEARCH
DESIGN Design a field study to include in the grant proposal Your proposal
should contain the following two sections
1 Study Design Construct and describe in detail an experimental or quasi-
experimental design to test the effectiveness of your intervention Describe in
detail the experimental groups (including how they will be constructed) the
research setting the sampling plan for study participants the treatment
manipulation and the data collection procedures Also indicate any control or
nuisance variables that may be measured
After describing the procedures write a justification of the design What threats
to validity does it rule out or limit and what threats to validity remain
II Measurement Describe the steps you would take to achieve valid and
reliable measure of the latent (conceptual) variable worker adjustment Your
team feels that as part of the proposal you must develop an original
operationalization of adjustment (thus you cannot simply use existing off the
shelf measures) Indicate in adequate detail how you would operationalize the
measure and indicate how you would demonstrate reliability and validity
B14 In describing their notion of the collective mind Karl E Weick and Karlene H
Roberts note Our focus is at once on individuals and the collective since only
individuals can contribute to a collective mind but a collective mind is distinct
from an individual because it inheres in the pattern of interrelated activities
among many people (p 360) Collective mind is not indexed by within-group
similarity of attitudes ideas or activities A collective mind is one in which
many people or many groups integrate their different attitudes ideas and
activities heedfully As Weick and Roberts note People act heedfully when
they act more or less carefully critically consistently purposefully attentively
studiously vigilantly conscientiously pertinaciously (p 361)
The idea of the collective mind as heedful interrelating is developed in the
following excerpt When people make efforts to interrelate these efforts can
range from heedful to heedless The more heed reflected in a pattern of
interrelations the more developed the collective mind and the greater the
capability to comprehend unexpected events that evolve rapidly in unexpected
ways When we say that a collective mind comprehends unexpected events we
mean that heedful interrelating connects sufficient know-how to meet situational
demands For organizations concerned with reliability those developments
often consist of unexpected non-sequential interaction (p366)
An example of heedful interrelating occurs as a pilot lands herhis aircraft on the
deck of an aircraft carrier The pilot does not actually land She is recovered
A recovery is an interrelated set of activities among air traffic controllers
landing signal officers the control tower navigators deck hands the helmsman
driving the ship etc These activities can be interrelated more or less heedfully
depending on the care with which the different units contribute represent the
situation and subordinate their activities to the single purpose of successful
recovery (p 363)
You are to design a two-part study
Part I You are to design a measurement study which assesses heedful
interrelating (ie collective mind) with a quantitative measure in a replication
of an aircraft carrier flight deck or other situation of your choosing Describe
your research strategies including operationalization of the variable selection of
the sample subjects data collection data analysis and so on for the purpose of
developing a measure of heedful interrelating
Part II Using the measurement tool developed in Part I and any other tools as
needed describe how you would design a study which would compare heedful
interrelating across organizations Choose at least one macro-organizational
variable (eg technology environment) as your basis of comparison Here you
must describe how you would make your selection of organizations to be
compared your data collection procedure data analysis and so on
B15 Many organizations in the United States have installed cross-functional teams to
counteract the silo mentality of traditional bureaucratic structure Preliminary
evidence of the effectiveness of cross-functional teams however is mixed --
some organizations have claimed success and others have reported failures The
evidence moreover is predominantly anecdotal--written for trade magazines by
the organizations themselves Since there have been few rigorous empirical
field studies assessing the effectiveness of cross functional teams the National
Science Foundation has decided to fund research on the topic
Assume that you are submitting a research proposal to NSF for a grant to
research the effectiveness of cross-functional teams Describe in detail and
thoroughly explain the research design sampling plan data collection
procedures ethical issues and proposed data analysis for your research design
Be sure to discuss the internal and external validity of your research Which
validity threats are ruled out and which remain NSF also requires that you
provide a statement and defense of the explicit philosophy of science underlying
your research Describe your philosophy of science and discuss how your
research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but
you must also demonstrate to NSF that you are a competent researcher It is
absolutely vital to NSF that the principal researcher (you) is knowledgeable
about the proposed research methodologies Therefore be sure that you always
carefully describe and give technical explanations for each component of your
research design and explain all technical terms (eg Cronbach alpha KR-20
Likert scale)
B16 Assume that you are submitting a research proposal to the Department of
Commerce (DoC) for a grant to research the effectiveness of virtual work teams
A virtual work team is a leaderless collection of individuals who are
geographically separate from one another and share their expertise using
internet media such as a listserver or Lotus notes The DoC requires that the
researcher use both qualitative and quantitative methods to gather data Describe
in detail and thoroughly explain the research design sampling plan data
collection procedures ethical issues and proposed data analysis for your
research design Be sure to discuss the internal and external validity of your
research Which validity threats are ruled out and which remain The DoC also
requires that you provide a statement and defense of the explicit philosophy of
science underlying your research Describe your philosophy of science and
discuss how your research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but
you must also demonstrate to DoC that you are a competent researcher It is
absolutely vital to DoC that the principal investigator (you) is knowledgeable
about the proposed research methodologies Therefore be sure that you always
carefully describe and give technical explanations for each component of your
research

5 MEASUREMENT
A) Measurement Terms
A1 There are four levels of measurement rigor in management research Discuss each
one What properties do measurements at each level have (ie how much
information do the numbers from each level of measurement convey) How can the
numbers be changed (transformed) and still retain the properties of their
measurement level Pick one construct from a favorite research domain and give an
example of an operationalization of that construct at each of the four levels of
measurement rigor (provide arguments about why you think those examples reflect
each level) Lastly treat each examplelevel as a dependent variable in some
statistical analysis Given an example of a statistical technique appropriate for
analyzing data at that level of measurement rigor
A2 Define (and discuss important features or issues concerning) the following
constructs measurement (Define any six terms)
1 Construct validity 6 Item analysis

estate agents self-assessment of performance Since there is no existing
measurement available you have to develop the instrument by yourself
Describe how you would develop the measurement assuming that you have no
idea of how many dimension the construct has
b) Suppose you have developed an instrument consists of 20 questions
measuring 4 dimensions (5 items per dimension) from (a) You collected data
from another 300 real estate agents to validate your instrument Explain how
TH
you would use structural equations model (SEM) to examine the reliability and
validity of the instrument What are other concerns about reliability and validity
that are not addressed by this approach
B2 The research and business world have been fascinated with the concept of
organizational culture However operationalizing this construct has been a
difficult task Discuss the ways in which the construct has been operationalized
(eg technique static v dynamic sample selection generalizability) Critically
analyze each of these methodologies Then choose a methodology you would
use to examine organizational culture and defend your choice Describe how
you would study culture and what more would be known about culture as a
result of your study
B3 Suppose you are setting out to develop a new measure of a construct You want
this measure to be used in survey research and you want to establish its validity
and reliability Your goal is to have at the end of the process a measure that is
defensible and likely to be widely accepted by other researchers studying that
construct What steps would you take to conduct such a program of research
For each step explain the purpose of that step explain why that step is
important explain what methods and statistical procedures you would employ at
each step and explain what evidence you would hope to gather at each step
B4 Assume you are interested in constructing a new measure of (fill in with a
relevant variable from your field) Detail the major concerns that need to be
addressed and the steps that need to be taken in working toward validating this
new measure
B5 Assume that you recently read an article on workplace violence which you
found very interesting The authors argued that one of the predictors of
workplace violence was a construct called propensity to be violent and used a
one-item measure as follows How likely are you to become violent when
provoked You had serious doubts about the authors measure and decided to
develop your own
(a) How would you go about developing items to measure propensity to be
violent
(b) How would you determine whether the instrument was reliable
How would you determine whether the instrument was valid
B6 A concern in organizations is retirement of baby boomers within the next 5 -
10 years This concern is focused on the loss of older employees with skills
critical to the core business functions of organizations In order to continue to
have employees with those critical skills it seems necessary to retrain some
older workers However past practice in most organizations has been not to
retrain older workers for a variety of reasons mostly financial A researcher
working for the Human Resources Department of a large corporation - 13500
employees in 12 different plant locations - hypothesizes that the major reason
for not retraining older workers is ingrained in the culture of the corporation
IC
The researcher feels that older workers are not as highly valued as younger
workers in terms of their potential usefulness after retraining The researcher
searched the literature but found nothing in the existing literature to measure
the cultural value construct What should the researcher do to establish a reliable
and valid self-administered paper and pencil measure of this construct namely
the value of retraining older workers

the complexity of an organizations manufacturing technology plays in
determining the level of centrality of decision making in the organization
Describe and justify the steps you might follow to develop an operationalization
of the concept of technological complexity What standards would you use to
determine if your operationalization is valid
B8 Organizational researchers have several strategies available to them for
gathering information (eg self-report measures archival measures direct
observation and trace measures) Assume that you are going to conduct
empirical research to assess the role that the structure of the organization plays
in determining the level of organizational effectiveness Briefly review the
strengths and weaknesses of the basic strategies (that is self-report measures
archival measures direct observation and trace measures) for measuring
organizational effectiveness Next describe and justify the steps you would
take to develop an operationalization of the concept of organizational
effectiveness What standards and procedures would you use to determine if
your operationalization is valid
B9 One of the most important topics of recent research has been stress in the work
place One of the most important problems with understanding this literature is
the varying definitions and measurement of this construct Suppose you had
decided to investigate the relationship between stress at the work place and dual
career family happiness
a Since there are multiple ways to measure stress in the work place describe
two ways to do this Hint - avoid using two self-report measures
b Describe how you would decide on the best single measure In doing so
describe the steps you would take in evaluating your measure Be sure to define
your meaning of validity and reliability It is important that your measure have
all the necessary psychometric characteristics so that other scientist can trust the
results of your research
c Be certain that you answer the question Validity for what
d In order to understand the results of your study you need to compare your
measure of stress at work with other measures of this construct How would you
do that
B10 Assume that you have been hired by a national survey research company
Shash Inc to write items that will be used in a national survey of attitudes
toward capital punishment There are a number of criteria that can be used to
guide your item writing What are they Briefly describe five (5) such criteria

impact of interpersonal trust on organizational decision making Describe and
justify the steps you might follow to develop an operationalization of the
interpersonal trust concept
B12 Assume that you are going to conduct empirical field research to assess the role
that employee empowerment plays in determining the level of organizational
commitment of employees Describe and justifyexplain the steps you would
follow to develop a valid and reliable operationalization of the concept of
employee empowerment
Explain the procedures and standards you would use to determine if your
operationalization is valid and reliable
How would you assess the construct validity of such a measure
Discuss issues concerning the level of observation of your measure and level of
analysis of the data
B13 Assume you are interested in developing a new scale to measure construct X
Further assume that you have used previous literature and your own conceptual
development to delineate 2 dimensions of X specifically XF1 and XF2
Describe the steps you would go through in developing testing and evaluating
this new scale With regard to testing and evaluating be sure to consider the
role of factor analysis (both exploratory and confirmatory) and item analysis
Also you will want to make sure that your new multidimensional scale shows
evidence of validity (several kinds) and reliability so be sure to examine these
issues and explain how specific information gathered from the above testing
contributes to these concerns
C) Reliability
4) What is reliability and why is it so important What are the different ways reliability can be
assessed and when is each appropriate
15) What does coefficient alpha assess What are the ways coefficient alpha can be increased
C1 Describe and discuss the concept of reliability and all of its various forms
including their assessment When is each form appropriate and what information
is provided by each index
C2 In establishing congruence between multiple measurements we often compute
indices of reliability andor indices of agreement These two types of indices
address very different questions Your task is to 1) Define reliability and
agreement 2) Explain when each is useful using examples in which one but not
the other is appropriate and 3) Briefly describe two reliability indices and two
agreement indices
C3 Explain reliability in terms of the classical test theory What are the
consequences of unreliable measures in hypothesis testing What are the factors

true test score theory domain sampling theory generalizability theory IRT)
Discuss the different approaches for estimating reliability and the contexts in
which each might be appropriate Use examples throughout
C7 What are the consequences of unreliability in a measure
C8 What are some of the conditions that might keep the internal consistency (eg
alpha) of a given measure low Is a low alpha always a sign of a problematic
measure
C9 Define reliability Name some methods of calculating reliability How well do
these methods map up with the definition of reliability What is the impact of the
number of test items and sample size on Chronbachs alpha and why would this
effect occur or not occur (Note Do NOT discuss inter-rater reliability)
C10 Schmidt and Hunter (1996) described several types of measures typically used in
organizational research and identified the type(s) of measurement error affecting
each of them in various situations For each measure below indicate the types of
error and sources of error that are most likely to affect it Then indicate what
could be done to reduce errors of measurement andor what can be done to
control for errors statistically
a Supervisor ratings of subordinates job performance
b Self-ratings of ones own job performance
c Self-reports of ones own job-related attitudes
d Sales figures for a salesperson (or production quantity for a production
worker)
d Aptitude tests taken as part of the hiring process
C11 Suppose you had conducted research on the relationship between organizational
commitment and rigidity of organizational structure in 200 firms Your measure
of rigidity was based on number of organizational authority levels and the degree
to which written organizational rules existed and defined role behaviors for
employees Thus an organization with a large number of organizational levels
and specific written policies defining appropriate role behaviors for employees
would score high on rigidity of organizational structure After analyzing your
data you find that there is a statistically significant negative correlation between
commitment and rigidity which is consistent with your hypothesis However the
reliabilities for your two measures are
(1) commitment = 23 (2) rigidity = 83
How should you interpret your results What could you do to fix this situation
Describe the specific steps (in order) you would follow to develop a more
reliable measure of commitment
C12 (a) Define the concept of reliability (of measures) in a clear concise and
accurate manner (b) Provide a formula that expresses the reliability of a measure
in terms of two components of variance ie total variance and the error
variance
D) Multi-level Assessment
D1 One of the major challenges for group-level research is the issue of aggregation of
individual data to the group level
(a) Under what conditions (eg types of data number of raters) should the various
interrater agreement and reliability methods be used (Rwg Kappa and Weighted
Kappa percent agreement average pairwise correlation ANOVA methods
(interclass correlation coefficient WABA)) What are the advantages and
disadvantages of each of the methods
(b) Explain the controversy between Frank Schmidt Larry James and others
regarding the differences between interrater agreement and interrater reliability
Who is right Do the differences matter in research practice
Defend your answers
(c) Review two articles from the organizational behavior literature that have had to
deal with aggregation issues Critique the methods the authors used to make
aggregation decisions
(d) Provide some advice to researchers regarding what they should do if interrater
agreement and reliability indices indicate that it is not legitimate to aggregate their
data
(e) Provide some ideas for avoiding the need to aggregate in group-level research
through creative research methods and measurement strategies
D2 Cross-levelmulti-level research is becoming more evident in the organizational
research literature This type of research raises many issues and presents many
challenges in terms of designing the research measuring variables and collecting
and analyzing the data Assume that you are interested in aggregating data (eg
from the individual to the group or from the firm to the industry) for one or more
variables What are the major issues you will need to deal with
D3 A researcher wants to measure organizational climate for continuous learning
Organizational climate is operationalized as a shared consensual aspect of the
organization -- the shared perception among employees that the organization values
and supports continuous learning Describe how you would measure organizational
climate in this case Specify (a) the level (ie individual group organization) at
which the construct exists (b) the level at which you would measure the construct
and (c) the procedures that you would use to establish that measurement is aligned
with theory (ie the construct validity of the measure)
E) General (Measurement)
E1 Studies in organizational behavior research often rely on single-item measures of
key constructs The use of single-item measures has long been criticized based
on the premise that single-item measures are unreliable However Wanous
(Wanous amp Hudy 2001 Wanous amp Reichers 1996 Wanous Reichers amp Hudy
1997) has recently argued that single-item measures can exhibit adequate
reliability Wanous based this conclusion on a procedure for estimating the
reliability of single-item measures using the classic formula for correction for
attenuation Subsequent studies have yielded mixed results regarding the
conclusions of Wanous (eg Loo amp Kells 1998 Nagy 2002) and the veracity
of the perspective advocated by Wanous remains in question Summarize and
assess the arguments for and against the use of single-item measures and
evaluate the procedure and evidence offered by Wanous regarding the reliability
of single-item measures Based on your assessment and evaluation develop
recommendations regarding the use of single-item measures in organizational
behavior research

E2 Ipsative measures have become prevalent in organizational behavior research
Ipsative measures ask respondents to answer questions relative to one another
such that the scores for all questions sum to the same constant for all respondents
Examples of ipsative measures include rankings Q-sorts and the allocation of a
fixed number of points (eg 100) across a set of response options Ipsative
measures may be contrasted with absolute measures which ask respondents to
answer questions independently from one another Absolute measures are
exemplified by rating scales using an interval or ratio numeric response format
The relative merits of ipsative and absolute measures have been debated for
decades (eg Cornwell amp Dunlap 1994 Hicks 1970 Johnson Wood amp
Blinkhorn 1988 Saville amp Wilson 1991 1992) yet the fundamental issues
underlying this debate have not been adequately addressed in organizational
behavior research For example measures of organizational culture and values
are often ipsative and some researchers advocate these measures over absolute
measures (eg Meglino amp Ravlin 1987 OReilly Chatman amp Caldwell 1991
Ravlin amp Meglino 1987 see also Rokeach amp Ball-Rokeach 1989) Review the
relative merits of absolute and ipsative measures Based on your review which
form of measurement is most appropriate and why Do your conclusions depend
on the construct being measured If so what types of constructs are best suited to
ipsative measures and what types are best suited to absolute measures Next
apply your conclusions to the measurement of culture and values in
organizations What specific arguments have been advanced in favor of ipsative
measures of culture and values How sound are these arguments Should ipsative
measures be used in the study of organizational culture and values If not how
can absolute measures of culture and values be developed that address the
concerns voiced by advocates of ipsative measures Provide a specific example
of the type of measure you would propose

facets of a concept Although such measures are prevalent and in some cases are
advocated (eg Law et al 1998 1999) they can present a variety of conceptual
and methodological problems Describe the specific problems associated with
measures that use items representing different facets of a concept Compare these
problems with the purported advantages of such measures Conclude by

E5 Suppose Roberta Von Eisenbrick is a researcher interested in the consequences of
AFFECTIVE CONFLICT (AC) in decision-making teams She gets access to a
variety of outcomes assessment committees at each of 87 different schools in
the Dallas Independent School District and gains permission to tape-record two
of their meetings (one in February and one in March) Such committees have
been formed to develop quantitative ways to track pursuit of school goals and
provide accountability to local and state governments These are often divisive
teams with heated meetings because what gets assessed is what usually gets
rewarded After both of these meetings the committee members each
fill out a short questionnaire that contains 20 Likert-type items measuring how
much AC occurred (eg People in our group often get angry with each other)
The individual scores are summed across items then averaged across team
members to come up with a group-level AC score for each of the 87 2
meetings The same procedures are followed for a 5-item measure of Group
Cohesiveness (GC) which is predicted to be reduced by higher levels of AC
Roberta also listens to every tape and from her expert judgment she rates each
groups meetings on the same 20 items Those 20 ratings are summed for each of
the 87 2 meetings Now Roberta is interested in evaluating her measure She
wants it to have excellent psychometric properties including reliability and
construct validity

definition to the context given above
b How could you estimate the reliability of this new measure of AC Cover at
least three kinds of estimates and the sources of error each one assumes or is
estimating Pick one of those kinds of estimates and provide a rationale for using
it
c What is construct validity Discuss how the (un)reliability of the AC measure
could affect the conclusions one would draw from a study involving it and GC In
your discussion be sure to go over the connection between reliability and
validity and the connection between reliability and the probability of Type I or
Type II statistical errors

B2 In recent years (and in not so recent years for that matter) methodologists have
criticized the fact that psychologists rely heavily on significance testing What
are the essential elements of these critiques What are some remedies to the
problems engendered by significance testing and why have these remedies not
been widely adopted
B3 (a) There is a debate among the IndustrialOrganizational psychologists on
whether we should abandon significance testing and report confidence intervals
instead Please summarize arguments from both sides and state your position on
this issue

things that researchers have inappropriately sanctified the p lt 05 level of
significance Describe and critique the arguments for and against the use of
statistical significance testing in empirical research What information other than

D) ModeratorsMediators
D1 Moderation and mediation provide different ways to model third variable effects
(a) Please define both of these terms (b) Sketch a conceptual model to show how
each relates to main effects (c) Using variables of your choice please write
hypotheses to reflect both (d) Explain how each is tested analytically
D2 Discuss moderators and mediators Provide an example of how (1) a moderating
variable influences the relationship between the independent and dependent
variable and how (2) a mediating variable influences the relationship between
the independent and dependent variable Describe how you would test for both
moderation and mediation using regression
D3 Many theories in organizational research predict that the effects of one variable
on another are moderated by a third variable Such moderator effects are
typically tested by entering the product of two variables as a predictor after
controlling for the two variables that constitute the product Several researchers
have pointed out that this product is often highly correlated with the squares of
the two constituent variables and have suggested that moderating effects may be
tested after controlling not only for the two constituent variables but also their
squares (eg Cortina 1993 Ganzach 1998 Lubinski amp Humphreys 1990
MacCallum amp Mar 1995) Discuss the strengths and weaknesses of this
approach as compared to methods that use only the product term and its
constituent variables Conclude with recommendations as to when and under
what conditions organizational researchers should test moderator effects with the
squares of the constituent variables in the equation

D4 Assume you are interested in studying relationships amongst three variables X
Y and Z Your first hypothesis posits Z as a mediator of the relationship between
X and Y Your second hypothesis posits Z as a moderator of the relationship
between X and Y Draw the figures depicting each of these hypothesized
relationships and describe (make sure to write regression equations) how you
would test each of these hypotheses
D5 The amount of time and effort that the average person pours into his or her job
has risen steadily over the last two decades such that the average person now is
working one more week per year than the average person in the mid 1970s This
steady increase has fueled research interest in the construct of Job Burnout (JB)
which is an emotional and physical exhaustion associated with ones work
Organizational Stress (OS) the perception of greater demands than available
resources in ones work environment is thought to be one of the chief
antecedents of JB However time spent under OS is thought to make its affects
on JB accumulate or worsen Work Role Withdrawal (WRW) the avoidance of
responsibilities or the deliberate reduction of inputs to ones job is believed to be
the chief consequence of JB
a Formally state these ideas as verbal hypotheses as equations and as a complex
directed graph (circle amp arrow diagram)
b Conceptually what is a mediator Define the term and identify the mediator in
your hypotheses in (a) What elements or steps in a study design (not statistics)
that would be helpful for detecting the mediating relationship that was proposed

subdomains of management Further demonstrate your understanding of
moderator variables by picking which variable in (a) is the moderator Show the
moderating relationship in an X-Y (or multi-layered) chart Again what elements
or steps in a study design (not statistics) would be helpful for detecting the
moderating effect implied above

F) Applied Data Analysis
16) Q Your departmental chair is considering a new textbook and has asked for your
recommendations You conduct a well-designed controlled study (details are unimportant) and discover students who use the new book perform 10 better on a standardized subject
matter exam than those using the old book (p = 027) Both books are readily availabe their prices are almost identical and both are equally acceptable to the instructors What is your recommendation to the chair
F1 Attached is the beginning of an article Your task is to write the results section by
1 making up and reporting plausible descriptive statistics that will help the
reader understand the results of the statistical tests you report and the nature of your
sample (Hint this can be presented in the form of a table)
2 describing and defending your choice of appropriate statistical tests of the
hypotheses and the steps that you would go through in carrying out these tests
3 making up and reporting results of these tests that are consistent with your
descriptive statistics and with any information in the rest of the article about the
results found (Hint this can be presented in the form of a table)
4 describing how well these results provide support for the hypotheses You
may want to note any relevant threats to validity here
Be sure to state any assumptions you make
F2 Assume that the Personnel Manager of a local firm Ms B dFlandres hired you to
analyze some data that her assistants had collected over the past several years The
data consist of (a) job performance ratings that were made in June of 1990 and (b)
scores on 25 predictor variables (eg measures of education job experience job
tenure job aptitude personality) that were measured when the individuals were hired
(between April 1987 and May 1988) She had data from only the 110 subjects (60
males and 50 females) who were hired during the period and were still employed by
the firm One objective of your analysis (analyses) is to determine how well the
performance criterion can be predicted by the predictors What strategy would you
use in analyzing the data Describeexplain (b) Is sample size an issue for your
analyses Explain If it is what will you do to deal with problems stemming from
sample size Assume that no additional data can be collected at this time (c) Some
preliminary analyses that you do reveal that five of the predictor variables correlate
(zero-order basis) about 75 with one another Will this influence the analyses that
you use Will it influence the validity of conclusions derived from your proposed
analyses (d) Ms dFlandres is interested in knowing if the predictor variables are
equally effective in predicting the job success of males and females What analysis
or analyses would you do to deal with this issue
F3 Assume that you have been provided with data on 12 conceptually distinct variables
that are moderately correlated with one another at the empirical level The data are
from students in four different college majors ie astronomy (A) biology (B)
criminology (C) and demography (D) The 12 measured variables fall into the
general categories of mental health (tension emotional withdrawal hallucinations
guilt feelings blunted affect and suspiciousness) and job satisfaction (work itself
supervision co-workers pay promotion prospects and working conditions) Your
task is to determine if the individuals in the four college majors differ from one
another on the 12 measured variables
(a) What statistical technique(s) would you use to test for group differences
Explain Be specific about the procedures(s) that you would use
(b) What statistical estimate would you use to estimate the extent to which the
groups differ from one another Be specific
F4 The following statistical table published in a recent issue of Work amp Occupations
was taken from an article discussing variables influencing resistance and citizenship
behaviors in the workplace Resistance behaviors include playing dumb withholding
effort work avoidance subverting particular managers and sabotage Citizenship
behaviors include cooperation engaging in peer training use of insider knowledge to
facilitate production commitment to organizational goals giving extra effort freely
Both measures are global constructs aggregated to the interval level and
standardized
The table reports the results of a series of ordinary least squares regression equations
with standardized coefficients Explain the meaning of the statistics presented What
do these statistics tell us generally about the relationship between resistance
behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows
Anomie Index -standardized interval level measure tapping multiple dimensions
The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)
F5 Researchers collected data from a sample of 350 companies on the following
variables
size (measured as number of employees)
Business Strategy (a nominal variable with 2 response options low-cost provider or
differentiator)
HR Strategy (a nominal variable with 2 response categories High commitment or
low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

as you see it within the time span of your career as an academic To do this use
examples of already written (or yet to be written) articles as models
J5 A frequent criticism of non-quantitative research summaries (literature reviews) is

affected the statistical outcomes of the studies included in the literature review Meta-
analysis however allows one to statistically examine such effects Assume you are
conducting a meta-analysis of the relationship between leader behaviors and group
productivity Briefly describe the steps you would take in conducting a meta-

model For each of those three statistical procedures describe and discuss the
following

assumptions usage and limitations
O3 How do exploratory and confirmatory factor analysis differ What are the
advantages and disadvantages of each
O4 Describe the differences between exploratory factor analysis (EFA) and
confirmatory factor analysis (CFA) When would you use one verses another
Are there ways to use EFA in a confirmatory way Can you use CFA in an
exploratory way Also describe the difference in principal components analysis
(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression
O6 The basic factor analysis model can be represented by the matrix algebraic
equation A B = C

information in each matrix and its purpose
(2) For what purpose do researchers use factor analysis Explain In the process
provide a very brief description of a study for which factor analysis would be a
useful data analytic technique
O7 Factor analysis is an important statistical technique in organizational research
Describe factor analysis as an analytical tool including the following issues
a the reasons for using factor analysis
b the type of data necessary for using the technique appropriately
c the type of quantitative output that results from applying the technique
d how a researcher would use the output in his or her research
e how confirmatory factor analysis is different from exploratory
f the important issues and problems in using the technique
P) Structural Equation Models
P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)
Please comment on these restrictions versus access argument Which side do you
take
What are the strengths of SEM Give some examples
What are the weaknesses of SEM Give some examples

cost only $25000 per team) could raise the performance of Bafkos teams The VP
however wanted to experimentally test the efficacy of this training program before
he adopted it widely throughout the firm So the consultant suggested the following
experimental test
There were 48 teams in Bafko that showed significant variation from month to
month in their level of performance The consultant chose the 24 worst performing
teams based on last months data and assigned them to the training group After
all he argued these were the ones who most needed it The other teams were
assigned to the control group The training group received the training program
(lasting one week) at the beginning of the next month while the control group
teams did their normal routine Performance scores were gathered at the end of the
month The results showed that the training group teams had a significantly larger
rise (ie statistically significant) in their performance than did the control group
teams (who as a group did not improve at all) The consultant proudly displayed
these results and argued that they convincingly demonstrated the efficacy of his
program
How would you advise the VP Specifically what is the validity of the consultants
conclusions If you think he might be mistaken what specific threats to internal
validity are particularly plausible
G5 Consider the following design
N O Xa O
N O Xb O
N O Xc O
N O O where
Xa Xb and Xc represent different levels of a training program that varied in its
length across three different work groups In group a the training time was 40
hours in group b it was 30 hours and in state c it was 20 hours The training was
designed to instill customer service values in the team members O represents a
measure of customer service attitudes measured with a 20-item Likert scale This
measure was administered one week before the training program and 3 months
later The researcher hypothesized that the training program would improve
customer service attitudes and that longer training would have stronger effects
The design is a non-equivalent groups design because people were not randomly
assigned to groups even though groups were randomly assigned to treatment
condition Each group has a sample size of 36 members The reliability of the
customer service attitude scale was 78 at the pretest and 80 at the posttest The
pretest means were as follows
Group A 26
Group B 23
Group C 27
Control Group 25
a Construct a regression model that will test the researchers hypothesis Be
explicit here describing each variable in the model and what regression effect(s)
you would expect to find if the hypothesis were correct (Hint everything you need
to know is in Trochims chapter 11 and what we discussed in class) (10 points)
b Describe any serious threats to internal validity (10 points)
c Discuss how you might amend this design to improve its internal validity(10
points)
G6 Often in organizational research the researcher is faced with having only one group
on which to experiment and thus cannot use a control group when conducting
experiments This occurs for example in taxation experiments when you cannot
selectively apply new tax laws to different groups or when you wish to test the
efficacy of an incentive plan that must be applied to all members of a company In
such situations the researcher must be creative in assembling a quasi-experimental
design that has high validity (and usually the challenge concerns internal validity)
Consider the following scenario
A manager of a retail store wants to test the efficacy of an incentive program in
changing the selling behaviors of her retail sales clerks Specifically she wants to
test a behavioral reinforcement program in which sales peoples behavior is
recorded on in-store video cameras The tapes are analyzed each night and the
experimenter tabulates the frequency of various behaviors (eg offering assistance
to customers restocking items straightening up displays suggesting accessory
items to accompany the items that a customer is purchasing) The manager then
rewards the clerks with a monetary bonus based on the frequency of desired
behaviors She would like to conduct a valid experiment to see what effect such an
incentive program has on employee behavior but because of concerns about
employee morale she cannot assign clerks to treatment and control groups Instead
she has to apply the experimental treatment to everyone in the store She learned in
her research methods class (which the company requires all its managers to take)
that a single group experimental design typically has very low internal validity
Your job as a consultant is to help her design an experiment given her constraints
that would produce interpretable (ie internally valid) results Describe the details
of the design you would recommend using the notation in Trochim (2001) If the
design you come up with has a specific name use it As part of describing your
design discuss how the data would be analyzed and what particular effect you
would look for
G7 Why are experimental research designs held in such high regard
G8 Compare and contrast experimental quasi-experimental and correlational research
designs What characteristics separate these three designs What are their
advantages and disadvantages especially in comparison to one another
G9 What is the difference between a within-subjects experimental design and a
between-subjects experimental design When might a within-subjects design be
appropriate When might it be inappropriate
G10 Describe the difference between a basic within subjects and between subjects
experimental design What are the advantages and disadvantages of each
especially in comparison to one another Give an example from your area of
research in which each would be appropriate
G11 What are the major threats to the internal validity of a pretest - post test
nonequivalent control group design How can this design be improved with regard
to increasing a researchers ability to make causal inferences
G12 A production manager is interested in testing the hypotheses that participation in
quality circle programs will result in increased productivity and reduced
absenteeism A questionnaire is administered to a group of 92 employees
concerning their attitudes toward such programs and 46 with the most favorable
attitudes who are willing to participate are selected for the treatment group The
remaining 46 are the control group Measures of performance (unitsmonth for the
group) and absenteeism (lost daysmonth for the group) are kept over a three month
period during which the treatment group has weekly quality circle meetings The
results are as follows
Month 1 Month 2 Month 3 Month 1 Month 2 Month 3
Performance Absenteeism
Treatment 100 115 121 6 9 4
Control 110 108 113 6 8 5
The manager calculates t tests between month 1 and 3 The only significant
difference is performance for the treatment group so the manager concludes that
quality circles raise productivity but do not have an effect on absenteeism What
are the primary threats to internal and external validity in this study What are
possible alternative explanations for the differences (or lack of differences)
between the two groups What additional information might help explain these
results
G13 One stream of current strategy research contains event studies In these studies
investigators basically correlate the reaction of a financial market to the presence
andor absence of the occurrence of some event at a firm (eg the resignation of a
CEO) In a different approach to such a study suppose that one investigator (Jean)
conducts a natural field experiment on the effects of competitor mergers on a
firms environmental scanning activity Through previous arrangement Jean has
been working with 5 medium-sized computer hardware and 5 medium- sized
software firms on the west coast Shes been collecting a paper trail of internal
memos reports and phone calls that might measure environmental scanning
activity Shes been finding that the firms in both industries do about the same
amount of scanning (no significant differences) However in the midst of her data
collection Norton announces a merger with Symantec (software) A year later
Jean compares the amount of post-merger environmental scanning in the software
industry with that in hardware industry Just as Jean had hypothesized a t-test
shows a greater amount of post-merger scanning among the software firms She
concludes that her hypothesis was supported mergers of competitors cause an
increase in scanning
Critique the study described above in terms of its design flaws Identify the design
Jean used Briefly allude to problems the study has with external validity but
concentrate on the Cook and Campbell threats to internal validity Provide a
rationale for why each threat is or isnt operating in the study Link each of the
relevant threats to the specific constructs being studied (mergers and environmental
scanning) Finally do a summary evaluation -- what can be learned from this
study
H) Quasi-Experimental Design
H1 The University of Mississippi observed that the graduation rate of students with poor
grades during their freshman year was much lower than those with better grades
Wanting to improve the chances of these low performing students they tested the
effects of a new rule for freshmen The rule stated the following At the end of their
first semester all students with a GPA between 200 and 225 must register for
EDUC 1003 during their second semester Students with a GPA lower than 200
were put on academic probation EDUC 1003 consisted of a course whose objective
was to help students develop good study skills The theory was that poor study skills
were a significant cause of poor academic performance and that study skills could
be learned
They wanted to evaluate the effectiveness of this intervention so they collected data
on the GPAs of students beginning with their first semester and continuing through
to their third semester At that point they wanted to analyze the data to determine
whether the new rule was making a significant difference in the students academic
performance
What is the best way to analyze these data to reach an interpretable conclusion
Describe your approach and then discuss the major threats to validity that it has
Their sample size of students was as follows
Total N= 3454 (these are students who completed all 3 semesters)
Number of students with first semester grades between 200 and 225 (and thus took
EDUC 1003) was 956
H2 A nationwide furniture company wants to determine if a diversity training
program will improve individual sales performance on the floors of its urban retail
outlets A group of 45 salespeople in one city were given two weeks of training
Measures of individual sales performance were taken once two months prior to the
program and once two months after Forty-five salespeople (who did not receive the
training) in a similar city had the same measures taken at approximately the same
points in time The training group increased their average weekly sales from $14000
to $16500 while the non-training group improved theirs from $13000 to $14500
The change for the training group is statistically significant the change for the non-
training group is not
How would the interpretation of these results in this quasi-experimental design
differ from a true experimental design What are the threats to internal validity in
the above study and how might they be operating (be specific) What additional
information and analyses would be useful in controlling for these threats
H3 An accounting firm is interested in determining if a re-training program will reduce
errors made by its audit teams A group of 45 auditors in the home office location
are given two weeks of re-training Measures of the frequency of detectable errors
are taken once two months prior to the program and once two months after Forty-
five auditors in similar office at a branch location have similar measures taken at
approximately the same points in time The training group reduced their average
number of errors per audit from 8 to 3 while the non-training group reduced theirs
from 11 to 9 The change for the training group is statistically significant the change
for the non-training group is not
How would the interpretation of these results in this quasi-experimental design
differ from a true experimental design What are the threats to internal validity in
the above study and how might they be operating (be specific) What additional
information and analyses would be useful in controlling for these threats
H4 Describe the main classes of threats to validity that are found in quasi-experimental
research designs
H5 Dr Delta an organizational development consultant was hired by a firm that has
600 pizza parlors nationwide to assist in implementing organizational changes that
he hopes will result in higher levels of job involvement At the outset of the study
subjects had jobs with very low levels of enrichment and were paid on an hourly
basis He designed an experiment in which stores were randomly assigned to one of
three treatment conditions Condition 1 subjects experienced job enrichment (JE)
and a change to performance-based pay (PBP) Condition 2 subjects experienced
only JE and Condition 3 subjects experienced only PBP The parlors were
sufficiently far apart from one another and communication among the parlors so
poor that subjects in any parlor were totally unaware of changes made in other
parlors At the end of 18 months he measured the job involvement levels of workers
and then tested for differences between the three conditions using a standard one-
way analysis of variance In view of Dr Deltas design answer the following
questions
How sound is Dr Deltas design Comment on the weaknesses of the design
I) Interrupted Time Series Design
I1 What threats to internal validity are and are not ruled out by an interrupted time series
design that includes the introduction of a treatment and its removal at a subsequent
time period List and explain In the process be certain that you provide a diagram
that illustrates such a design
J) Validity Some Questions are about the validity of a measure others about experimental validity)
10) Identify four threats to internal validity and briefly describe what they mean
J1 It was some time ago that the tripartite view of validity was abandoned in favor of a
unitarian view in which different evidentiary bases for validity might be put forward
Binning amp Barrett (1989) represent an attempt to place multiple evidentiary bases into a
single framework Cook amp Campbell (1979) describe four aspects of validity but they
arent really meant to represent evidentiary bases Adding to the confusion is the fact
that while Binning amp Barrett and Cook amp Campbell use some of the same terms these
two pairs of authors clearly mean different things by these terms and intend for them to
be used in different ways Your task is to 1) Describe the evidentiary bases discussed
by Binning amp Barrett 2) Describe the aspects of validity described by Cook amp
Campbell 3) Describe the similarities and differences between the two lists including
the different purposes served by the two lists and 4) Present a single framework that
incorporates both This last task is the most important of the four
J2 What are the types of validity How would each affect an empirical study IC
J3 Define both internal and external validity Which is more important (it is not okay to
say that they are equally important) Defend your reasoning
J4 Why might someone argue that the construct validity of a measure can never really be
established
J5 Describe each of the following forms of validity content convergent discriminant
criterion-related and construct How is each assessed How do they related to each
other Which is most important (Make sure you defend your answer)
J6 Define and explain 6 of the 8 types of validity listed below and describe the type(s) of
information each provides Choose one specific type of study as an example (eg
cross-sectional study experiment quasi-experiment simulation ethnography etc) and
compare and contrast the usefulness and importance of each type of validity for that
type of study
-- Concurrent validity
-- Construct validity
-- Content validity
-- Convergent validity
-- Discriminant validity
-- Statistical conclusion validity
-- Internal validity
-- External validity
J7 Designing empirical research has been called making a series of trade-offs
Unfortunately decisions that are made to increase one desired quality (like internal
validity) can also decrease another desired quality (like external validity) For each of
the issues below discuss the concerns involved (ie the trade-off) and identify the
qualities that are being increased or decreased
a laboratory vs field study
b using a 5-item measure vs a 1-item measure
c using a student sample vs a sample of full-time employees
d using a sample of employees from one company of 5000 vs 500 employees from
each of 10 companies
e collecting your data using one method vs collecting your data using multiple
methods
J8 There are four major types of validity in social science internal validity external
validity construct validity and statistical conclusion validity Please address the
following three issues concerning validity
a What is the meaning of the four major forms of validity (ie internal and external
validity construct validity statistical conclusion validity)
b Are there trade-offs that can or must be made among the four types of validity
d Describe how the concept of validity varies across the research traditions of
experimental vs observational research
IC
J9 The quality of research is often assessed by examining validity issues As you are
aware there are numerous typesforms of validity (eg internal and external validity
construct validity statistical conclusion validity) These types of validity address
different aspects of the research process For this question please address the following
issues
a What is the meaning of the four major forms of validity (ie internal and external
validity construct validity statistical conclusion validity)
b Should there be a priority among these forms of validity If yes why If no why not
c Does the concept of validity vary across research traditions (ie experimental vs
observational research) If yes why If no why not
J10 External validity has received considerable attention in the social and behavioral
sciences Some researchers argue we are too concerned with the external validity of our
findings while other researchers argue that we are too unconcerned with external
validity Several points of view have been developed to explain what is external
validity When answering this question please be sure to address at least the following
issues
a Compare and contrast alternative conceptualizations of external validity
b Some researchers have argued that the role of external validity is invariant across
research traditions (ie experimental vs observational research) Defend the
perspective that the role external validity is invariant across these two research
traditions In addition present the weaknesses of this perspective
J11 In designing a research study researchers must consider trade-offs between internal and
external validity Explain what is meant by internal validity and external validity What
is the nature of these trade-offs How would you evaluatedetermine which is more
important internal or external validity for a particular study Why is this such an
important issue in organizational studies
J12 A researcher conducted a quasi-experiment to test the effects of participative decision
making (PDM) on job attitudes of employees Employees from different departments in
a large organization were assigned to either a treatment group (PDM implemented) or a
control group (no PDM) Random assignment was not possible because of work
schedules coordination of tasks etc Thus the design can be considered an untreated
control group design with pretest and posttest and is represented as follows (where
O=observation X = treatment)
________________
O1 X O2
-------------------------
O1 O2
_________________
The results of the experiment are presented in the graph below [no graph provided]
The dependent variable is job satisfaction and is measured on a 100 point scale (with
100 being extremely satisfied) How amenable are these results to causal interpretation
What is (are) the major threat(s) to internal validity B if any B for this type of design
given these results What steps can be taken to assess the extent of this (these)
threat(s)
K) Data Collection Methods
14) Describe the various methods of data collection (eg survey interview observation etc)
available to a social scientist What are the advantages and disadvantages of each relative to
each other
K1 Within micro organizational research much criticism has been raised concerning
the reliance on self-report survey data What potential problems does self-report
survey research raise How big of a problem do you think this is
K2 There are a number of methods for collecting data (eg survey interview archival
etc) that are available to a social scientistorganizational researcher Discuss each in
terms of their strengths and weaknesses both on their own and in comparison to one
another
K3 Pick an important construct in your favorite area of management research for which
there is some controversy about how it should be measured or operationalized (eg
environmental munificence or growth need strength) Give the prevailing verbal
definition of the construct and analyze the measurement controversy from two
broad angles First discuss how the controversy may or may not stem from claims
about how one measure is better or worse than another because it (or the other) is an
(a) archival record (b) direct observation (c) social report or (d) self-report That is
what are the relative strengths and weaknesses of each of these types of
measurement for the construct youre discussing Second discuss the construct
validity of the most commonly used measure(s) of this construct To answer this
second part you need to discuss just what construct validity is and how it can or
cannot be demonstrated In the situation you describe what could be done to
demonstrate or improve the construct validity of existing measures
K4 Interviewing in some form has been the workhorse for data collection in a variety
of research traditions positivistquantitative ethnographic feministpost-modernist
and increasingly historical research While each tradition elicits information from
respondents the goals and processes involved in interviewing vary considerably
across research traditions Discuss the purposes of the interview the relationship
between data and theory the roles assumed by the interviewer and the respondent
and the relevant criteria for assessing the validity and reliability of the information
obtained In addition compare and contrast the use of the interview as a data
collection method in the positivistquantitative tradition with its use in one of the
alternative traditions
L) Common Method Variance
L1 Many of us have had concerns about the reviews of our survey research which
suggest that data analyses of surveys are biased because of common method
variance effects of individual differences such as negative mood negative
affectivity and social desirability and the reliability and validity of the constructs
we are attempting to measure Define how these problems affect a research issue in
organizational behavior and the steps that might be taken to minimize such potential
criticisms of papers based on analyses of self-reported data through survey
instruments
L2 In a series of papers by Spector (1994) Schmitt (1994) and Howard (1994)
published in the Journal of Organizational Behavior arguments were provided for
and against the use of self-report questionnaire measures One of the issues
discussed that could limit conclusions drawn from relationships observed using self-
report measures was method variance What is meant by method variance what are
its sources and what impact is it expected to have on research findings
M) Sampling
M1 The manufacturing census samples all plants of 250 employees or more For
plants of 5-249 employees it takes a size proportional sample Plants of 1-4
employees are not sampled What challenges does this sampling method provide
to researchers What could you do to account for these problems if you were
TH
studying organizational (not plant) growth
M2 New York State has approximately 250000 employees in over 70 state agencies
commissions and boards ranging in size from approximately 50 to over 5000
employees Assume that you wanted to draw a representative sample of 1000
employees Describe two ways that you could draw such a sample and briefly
describe the advantages and disadvantages of each of these sampling approaches
IC
M3 The director of a national non-profit agency with approximately 10000
employees located primarily in regional offices in each of the 50 states the
United States has approached you and asked you to develop a study
(organizational survey) of organizational culture within the agency The agency
is about to embark on a variety of change initiatives including developing team
structures and the study is meant to examine various elements of organizational
culture that are potential barriers to change The director has indicated that he
would like to have the data analyzed at both the individual and office level of
analysis Because of funding limitations the agency will only be able to send the
survey to 1000 employees The director has indicated that there are three ways
of sorting employees all employees listed alphabetically all employees listed
alphabetically by state and all employees listed alphabetically by region (there
are between five and ten regions per state) Given these three ways of sorting
employees describe at least three different sampling approaches and the
advantages and disadvantages of each
M4 In your role as Teacher of Organizational Studies you are asked to prepare a
tutorial for beginning doctoral students on sampling design Assume that this
tutorial is part of a basic class in research design and that students in this class
have had a basic statistics course up to and including multiple regression Your
tutorial should focus on briefly defining and explaining the differences between
probability and non-probability samples You should make sure to present and
describe several types of probability samples (eg random systematic
stratified etc) and non-probability samples (eg convenience snow-ball quota
etc) and discuss general principles for when to use a probability vs a non-
probability sampling design For each sampling design you should also provide
at least one clear example of a situation where this type of sampling design is
appropriate
N) Cross-Cultural Research
N1 Discuss the problems in conducting cross-culturalnational comparison in terms
of (1) conceptualization and (2) research design and data collection
Define the three levels of measurement invariance How would the problems that
you have identified in part (a) affect measurement invariance How would you
examine measurement invariance by confirmatory factor analysis
TH
N2 Explain why using national boundaries as independent variable in cross-cultural
studies may not be appropriate in terms of theory and research methods What
alternative ways would you recommend
IC
O) General
O1 In your readings research has been described as choices among conflicting goals
(desiderata) For instance when choosing among research strategies a researcher
must choose among the desiderata of precision realism and generalizability The
trade-offs among desiderata occur for all aspects of research that is for the selection
of theories the treatment of independent variables research strategies the selection
of the problem to study rules of evidence for determining the meaningfulness of a
research finding and even the frameworks that describe the research process
Discuss what you see as the major trade-offs for each of the following aspects of
research That is discuss what you see as the major strengths and weaknesses
(advantages and disadvantages) of each aspect
a The trade-offs between internal and external validity
b The manipulation of the independent variable vs the observation of the
independent variable
c Basic vs applied research
3 DESIGNING A RESEARCH STUDY
A) General (Research Design)
3) Why is control so important in research design What are the different ways it can be
achieved (give a brief description of each control method) What are advantages and
disadvantages of each
A1 It has become almost a truism to note that the choice of methods influences theory
and questions data and conclusions (the causal direction might also be reversed)
Briefly discuss how the methods used have influenced research in any two of the
following areas leadership power and politics organization culture organization
justice Compare and contrast as possible Suggest some potentially fruitful
methodological directions for future work in these same topical areas and dont be
shy about reflecting on broader issues of how the field of organizational behavior
constructs its realities Lastly tie your discussion and reflections back to your own
future as a researcher what lessons or guidance do you derive from your
understanding of these issues
A2 Characterize as fully as possible what you see to be the methodological approach or
approaches in strategic management research Is there a dominant method or a wide
variety Discuss the reasons for the situation What are the advantages benefits etc
of the approach(es) in use What assumptions (ontological epistemological
ideological) do they embody Are current efforts ideal or at least adequate Are
there other approaches that could be useful If so how might researchers be
encouraged to use these as well If you see no advantage to more variety in
methodological approach support that point of view
A3 Describe a research question or area of interest to you and why you think it is not
only of interest but significance Using your understanding of research methodology
describe two ways of pursing the question that are as divergent on as many
dimensions as you can imagine Describe the advantages and disadvantages of each
approach How strong a link or fit is there between a research question and a
method
A4 In his 1957 article entitled The two disciplines of scientific psychology Cronbach
discussed the assumptions goals and methods used in experimental methods and
correlational methods in psychology
a According to Cronbach what is the main difference between the two disciplines
b Discuss the strength and weaknesses of each discipline
c What if anything could be done to improve the situation
B) Designing a Research Study
B1 Cook and Campbell describe the experiment as the research design with the
greatest methodological rigor However given the constraints present in most
organizations I-O Psychologists cannot often conduct experiments in applied
settings and must settle for techniques with less control than experiments
Describe a study to investigate the relationship between participation in a
supervisor training program and work performance which could realistically be
conducted in an organization If an experiment is not possible describe how you
would go about maximizing your ability to draw valid conclusions from your
design
B2 The XYZ Co has recently developed a sexual harassment web-based training
program The developers claim the program will cut training time and costs and
will be as effective or more effective than classroom-based sessions They
believe that this will be due to the increased availability of the program and the
ability for participants to review program material on demand Before the XYZ
Co developers launch this product they want you to determine if their claims
have merit Explain how you would design a study for this purpose
B3 Research suggests that demographic diversity improves group creativity but
reduces group efficiency Some argue that demographic diversity is just a proxy
for value and experience diversity and that demographic diversity on its own is
meaningless Design a test to settle this argument
TH
B4 E-mail has become a common form of communication in organizations and is
used for both formal and informal communication Because it has become so
IC
popular some people complain that the frequent use of e-mail leads to
miscommunication because they receive communications in e-mail that should
be accomplished through face-to-face or telephone conversations where there is
an opportunity for interaction You are interested in looking at this
phenomenon You are most interested in describing how e-mail is used for both
formal and informal communication and in examining the effect of the e-mail
use on organizational communication effectiveness Design empirical research
to address those issues
Describe your study in detail thoroughly explaining the research design
sampling plan data collection procedures ethical issues and proposed data
analysis for your research design Be sure to discuss the internal and external
validity of your research Which validity threats are ruled out and which
remain
REMEMBER Be thorough Your research design should demonstrate that you
are a competent researcher who is knowledgeable about the proposed research
methodology or methodologies Therefore be sure that you carefully describe
and give technical explanations for each component of your research
B5 Choose a specific situation involving employee selection eg artists for an
advertising agency (a) What strategy would you use in selecting the selection
measures (b) How would you combine the measures eg which measures
would you combine in a compensatory manner and which is a noncompensatory
manner (c) How would you assume test fairness defining various measures of
the term (d) How would you make final selections (e) How would you
validate your procedure (f) What considerations would enter in if your
company were too small to provide validation data (g) What difference would
it make if you were developing a procedure for deciding whether trainees
should be promoted as opposed to making new hires Please note--emphasize
but do not limit yourself to statistical issues
B6 There is evidence in the marketing literature of a non-monotonic relationship
between the expectations that customers have for retail service and their
eventual level of satisfaction with that service That is as a customers
expectations for service increase so does their eventual service satisfaction --
up to a point After that point the greater the expectations the lower the
eventual satisfaction Develop a hypothesis that includes a moderator variable
that might account for this evidence Give some reasonable rationale for it State
your hypothesis verbally as an equation as a directed graph (circle amp arrow
diagram) and as an X-Y function chart Discuss how it would or would not be
possible or useful to test your hypothesis via a laboratory experiment In your
discussion cover how and why a researcher could (not) manipulate the
independent constructs involved (mode X) whether or not random assignment
to conditions (mode R) is possible (including how may conditions would be
necessary) which alternative constructs could or could not be controlled (mode
K) and which constructs should be measured (mode Y)
B7 Assume you are the chairperson of a committee that must evaluate
undergraduate programs at your university Your task as chairperson is to
devise an approach (a design a research strategy a set of measures) that will
allow you to evaluate undergraduate programs Make sure that your approach
can be used in the future and at other comparable universities When developing
your plan be sure to address at least the following issues
a the type of design you would select Compare and contrast the selected design
with another possible design
b the type of research strategy you would select Compare and contrast with
another possible strategies
c discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
B8 Assume you are an organizational research design expert assigned to the
Strategic Planning Department of a large multi-national manufacturing firm
The Department has developed a new PC-based software package called
STRATPACK The software (and a one-week training course to learn how to
use it) is intended to improve the long-range planning ability of middle and
upper-level managers
Your job as research design expert is to devise research (a design a research
strategy a set of measures) that will allow you to evaluate the effectiveness of
the STRATPACK program Describe a research design for evaluating the
program Make sure that your research approach can be used in the future and at
all sites in the company When developing your plan be sure to address at least
the following issues
a discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
b the type of design you would select (eg a design where you manipulate the
independent variable versus observe the independent variable) Compare and
contrast the selected design with another possible design
c how your design deals with the major forms of validity Be sure to examine at
least internal external and construct validity
B9 Assume you are a consultant hired to evaluate the effectiveness of an industrial
safety program undertaken by a large manufacturing organization The safety
program is a behavioral one that provides rewards such as monetary bonuses or
extra paid vacation days for safety behaviors in terms of accident-free days
weeks etc Your task is to devise an approach (a research strategy a design a
set of measures and a general analysis strategy) that will allow you to evaluate
the safety program Because of the potential for the influence of many
extraneous variables on any safety program it is difficult to design research a
single cross-sectional study than can evaluate the impact of a single safety
program How would you design a study to evaluate the impact of the safety
program When developing your plan be sure to address at least the following
issues
a the type of research strategy you would select Compare and contrast with
another possible strategies
b the type of design you would select Compare and contrast the selected design
with another possible design
c discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
B10 One of the most important areas of research is forecasting of human resources
needs based on strategic positions of organizations For example NY State must
carefully forecast its human resources needs as it proceeds with significant lay-
offs of state employees Future human resources needs are generally evaluated
by either statistical ie regression or simulation or clinical judgment i e
supervisors judgments methods
a Design a single study that addresses the empirical question of whether
statistical or judgmental methods are better for forecasting human resources
needs You may discuss a program of research but please be quite specific in
your description of the first study
b What are the critical methodological issues in doing this kind of research
c What are the critical applied (or practical) issues in doing this research
d Are the issues in b and c related
B11 In the past decade computinginformation technology has changed many
aspects of organizational life For example the technology can make increased
decentralization possible by improving communication between central offices
and field offices Computer networks and word processors can enhance group
empowerment by making it possible for team members to create and edit
written group products quickly even if the individuals are at different locations
Some have argued that computinginformation technology will foster the
paperless productive office nevertheless others argue that the technology only
increases paper and reduces office productivity You are applying to the
National Science Foundation for a grant to conduct research that examines the
impact of computing information technology on organizational decision
processes The NSF application procedure imposes five basic requirements that
your research design must fulfill in order to receive funding Note A very
significant factor affecting NSF grant decisions is a clear demonstration that the
researcher is knowledgeable about the research methodology used Write your
response to each of the following five grant requirements Be sure not only to
respond to the requirement but also to demonstrate your research
competence
1You must design a study that uses two different methods
(interviewobservation survey experiment or quasi-experiment) Describe your
two methods in detail and provide a rationale for the key elements (eg
sampling data collection proposed analysis) of your methods Be sure to
discuss and evaluate the internal and external validity of both methods
2 As part of your research design you must select a conceptual (latent) variable
central to your proposal (use centralization of decision making as your
variable) and describe how you will develop your own measure (You may not
simply use off the shelf instruments)
3 You must describe how you will test for the reliability of the measure
(centralization of decision making) you developed in step 2 The NSF insists
that you describe how you will evaluate both the temporal stability and the
internal consistency of your measure Be sure to discuss what temporal stability
and internal reliability mean and how they are related
4You must describe how you will assess the validity of the measure
(centralization of decision making) you developed in step 2
5 NSF requires a brief statement and defense of the philosophy of science
underlying your research Discuss your position and show how your research
design is consistent with your philosophy
B12 Many organizations in the United States economy have installed some form of
Empowered Teams as an alternative or supplement to traditional bureaucratic
structure Preliminary evidence of the effectiveness of empowered teams
however is mixed--some organizations have claimed success and others have
reported failures The evidence however is predominantly anecdotal--written
for trade magazines by the organizations themselves There are few rigorous
empirical studies assessing the effectiveness of empowered or self-managed
teams You are applying to the United States Department of Labor (USDOL) for
a grant to conduct research that examines the effectiveness of empowered
teams The application procedure of the USDOL imposes three requirements
that your research design must fulfill in order to receive funding Write your
response to each of the three grant requirements The importance of each section
is implied by the evaluation points allocated by the USDOL to each of the three
requirements given in parentheses
1 (50 points) Your study design for assessing Empowered Team effectiveness
must use two different methods (interview observation archival analysis
survey simulation experiment or quasi-experiment) Describe in detail and
thoroughly explain the sampling plan instrumentation data collection
procedures and proposed data analyses for both methods Be sure to discuss the
internal and external validity of both methods and how the two methods
complement one another
2 (30 points) As part of your research design you must select one conceptual
(latent) variable central to your proposal and describe how you will develop
your own operationalization of the measure (You may not simply use off the
shelf instruments) Use the concept of group morale to demonstrate your
operationalization methodology Be sure to explain very explicitly to the
USDOL how you will assess the validity and reliability of the group morale
measure you are developing
3 (20 points) The USDOL traditionally has funded research conducted only
within the general paradigm of logical positivism but now is more open to other
research paradigms as well Your grant proposal must provide a statement and
defense of the explicit philosophy of science underlying your research Describe
your philosophy of science and show how your research design is consistent
with your philosophy
REMEMBER Be thorough You not only must design effective research but
you also must demonstrate to the USDOL that you are a competent researcher
It is absolutely vital to the USDOL that the principal researcher is
knowledgeable about the proposed research methodologies Therefore be sure
that you always carefully describe and give technical explanations for each
component of your research design and explain all technical terms (eg
Cronbach alpha KR-20 Likert scale)
B13 Assume that you are working as part of a research team that is responding to a
RFP (Request for Proposals) from a funding agency for research on work
socialization and newcomer adjustment The RFP calls for rigorous field
research that tests the effectiveness of theory-based interventions aimed at
facilitating the adjustment of new organizational members to complex andor
stressful work conditions The major goal of your teams research is to test the
effectiveness of a self-regulation intervention which trains newcomers to
identify and use relevant social information and cues to regulate work behavior
Your group hypothesizes that self-regulation training will be more effective
than other common treatments or interventions (eg realistic job previews
institutionalized socialization tactics)
You have been included in the team because of your methodological expertise
Your role is to design a rigorous field experiment or quasi-experiment to test he
effectiveness of the self-regulation training program REMEMBER THE
MAJOR CRITERION FOR FUNDING IS THE RIGOR OF THE RESEARCH
DESIGN Design a field study to include in the grant proposal Your proposal
should contain the following two sections
1 Study Design Construct and describe in detail an experimental or quasi-
experimental design to test the effectiveness of your intervention Describe in
detail the experimental groups (including how they will be constructed) the
research setting the sampling plan for study participants the treatment
manipulation and the data collection procedures Also indicate any control or
nuisance variables that may be measured
After describing the procedures write a justification of the design What threats
to validity does it rule out or limit and what threats to validity remain
II Measurement Describe the steps you would take to achieve valid and
reliable measure of the latent (conceptual) variable worker adjustment Your
team feels that as part of the proposal you must develop an original
operationalization of adjustment (thus you cannot simply use existing off the
shelf measures) Indicate in adequate detail how you would operationalize the
measure and indicate how you would demonstrate reliability and validity
B14 In describing their notion of the collective mind Karl E Weick and Karlene H
Roberts note Our focus is at once on individuals and the collective since only
individuals can contribute to a collective mind but a collective mind is distinct
from an individual because it inheres in the pattern of interrelated activities
among many people (p 360) Collective mind is not indexed by within-group
similarity of attitudes ideas or activities A collective mind is one in which
many people or many groups integrate their different attitudes ideas and
activities heedfully As Weick and Roberts note People act heedfully when
they act more or less carefully critically consistently purposefully attentively
studiously vigilantly conscientiously pertinaciously (p 361)
The idea of the collective mind as heedful interrelating is developed in the
following excerpt When people make efforts to interrelate these efforts can
range from heedful to heedless The more heed reflected in a pattern of
interrelations the more developed the collective mind and the greater the
capability to comprehend unexpected events that evolve rapidly in unexpected
ways When we say that a collective mind comprehends unexpected events we
mean that heedful interrelating connects sufficient know-how to meet situational
demands For organizations concerned with reliability those developments
often consist of unexpected non-sequential interaction (p366)
An example of heedful interrelating occurs as a pilot lands herhis aircraft on the
deck of an aircraft carrier The pilot does not actually land She is recovered
A recovery is an interrelated set of activities among air traffic controllers
landing signal officers the control tower navigators deck hands the helmsman
driving the ship etc These activities can be interrelated more or less heedfully
depending on the care with which the different units contribute represent the
situation and subordinate their activities to the single purpose of successful
recovery (p 363)
You are to design a two-part study
Part I You are to design a measurement study which assesses heedful
interrelating (ie collective mind) with a quantitative measure in a replication
of an aircraft carrier flight deck or other situation of your choosing Describe
your research strategies including operationalization of the variable selection of
the sample subjects data collection data analysis and so on for the purpose of
developing a measure of heedful interrelating
Part II Using the measurement tool developed in Part I and any other tools as
needed describe how you would design a study which would compare heedful
interrelating across organizations Choose at least one macro-organizational
variable (eg technology environment) as your basis of comparison Here you
must describe how you would make your selection of organizations to be
compared your data collection procedure data analysis and so on
B15 Many organizations in the United States have installed cross-functional teams to
counteract the silo mentality of traditional bureaucratic structure Preliminary
evidence of the effectiveness of cross-functional teams however is mixed --
some organizations have claimed success and others have reported failures The
evidence moreover is predominantly anecdotal--written for trade magazines by
the organizations themselves Since there have been few rigorous empirical
field studies assessing the effectiveness of cross functional teams the National
Science Foundation has decided to fund research on the topic
Assume that you are submitting a research proposal to NSF for a grant to
research the effectiveness of cross-functional teams Describe in detail and
thoroughly explain the research design sampling plan data collection
procedures ethical issues and proposed data analysis for your research design
Be sure to discuss the internal and external validity of your research Which
validity threats are ruled out and which remain NSF also requires that you
provide a statement and defense of the explicit philosophy of science underlying
your research Describe your philosophy of science and discuss how your
research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but
you must also demonstrate to NSF that you are a competent researcher It is
absolutely vital to NSF that the principal researcher (you) is knowledgeable
about the proposed research methodologies Therefore be sure that you always
carefully describe and give technical explanations for each component of your
research design and explain all technical terms (eg Cronbach alpha KR-20
Likert scale)
B16 Assume that you are submitting a research proposal to the Department of
Commerce (DoC) for a grant to research the effectiveness of virtual work teams
A virtual work team is a leaderless collection of individuals who are
geographically separate from one another and share their expertise using
internet media such as a listserver or Lotus notes The DoC requires that the
researcher use both qualitative and quantitative methods to gather data Describe
in detail and thoroughly explain the research design sampling plan data
collection procedures ethical issues and proposed data analysis for your
research design Be sure to discuss the internal and external validity of your
research Which validity threats are ruled out and which remain The DoC also
requires that you provide a statement and defense of the explicit philosophy of
science underlying your research Describe your philosophy of science and
discuss how your research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but
you must also demonstrate to DoC that you are a competent researcher It is
absolutely vital to DoC that the principal investigator (you) is knowledgeable
about the proposed research methodologies Therefore be sure that you always
carefully describe and give technical explanations for each component of your
research

5 MEASUREMENT
A) Measurement Terms
A1 There are four levels of measurement rigor in management research Discuss each
one What properties do measurements at each level have (ie how much
information do the numbers from each level of measurement convey) How can the
numbers be changed (transformed) and still retain the properties of their
measurement level Pick one construct from a favorite research domain and give an
example of an operationalization of that construct at each of the four levels of
measurement rigor (provide arguments about why you think those examples reflect
each level) Lastly treat each examplelevel as a dependent variable in some
statistical analysis Given an example of a statistical technique appropriate for
analyzing data at that level of measurement rigor
A2 Define (and discuss important features or issues concerning) the following
constructs measurement (Define any six terms)
1 Construct validity 6 Item analysis
2 Likert scaling 7 Semantic differential
3 Cronbachs alpha 8 True score
4 Unobtrusive (trace) measurement 9 Generalizability theory
5 Interval scale 10 Criterion-related validity
11 Sociometric choice measures
B) Operationalization
B1 a) You are conducting a study which requires you to measure Hong Kong real
estate agents self-assessment of performance Since there is no existing
measurement available you have to develop the instrument by yourself
Describe how you would develop the measurement assuming that you have no
idea of how many dimension the construct has
b) Suppose you have developed an instrument consists of 20 questions
measuring 4 dimensions (5 items per dimension) from (a) You collected data
from another 300 real estate agents to validate your instrument Explain how
TH
you would use structural equations model (SEM) to examine the reliability and
validity of the instrument What are other concerns about reliability and validity
that are not addressed by this approach
B2 The research and business world have been fascinated with the concept of
organizational culture However operationalizing this construct has been a
difficult task Discuss the ways in which the construct has been operationalized
(eg technique static v dynamic sample selection generalizability) Critically
analyze each of these methodologies Then choose a methodology you would
use to examine organizational culture and defend your choice Describe how
you would study culture and what more would be known about culture as a
result of your study
B3 Suppose you are setting out to develop a new measure of a construct You want
this measure to be used in survey research and you want to establish its validity
and reliability Your goal is to have at the end of the process a measure that is
defensible and likely to be widely accepted by other researchers studying that
construct What steps would you take to conduct such a program of research
For each step explain the purpose of that step explain why that step is
important explain what methods and statistical procedures you would employ at
each step and explain what evidence you would hope to gather at each step
B4 Assume you are interested in constructing a new measure of (fill in with a
relevant variable from your field) Detail the major concerns that need to be
addressed and the steps that need to be taken in working toward validating this
new measure
B5 Assume that you recently read an article on workplace violence which you
found very interesting The authors argued that one of the predictors of
workplace violence was a construct called propensity to be violent and used a
one-item measure as follows How likely are you to become violent when
provoked You had serious doubts about the authors measure and decided to
develop your own
(a) How would you go about developing items to measure propensity to be
violent
(b) How would you determine whether the instrument was reliable
How would you determine whether the instrument was valid
B6 A concern in organizations is retirement of baby boomers within the next 5 -
10 years This concern is focused on the loss of older employees with skills
critical to the core business functions of organizations In order to continue to
have employees with those critical skills it seems necessary to retrain some
older workers However past practice in most organizations has been not to
retrain older workers for a variety of reasons mostly financial A researcher
working for the Human Resources Department of a large corporation - 13500
employees in 12 different plant locations - hypothesizes that the major reason
for not retraining older workers is ingrained in the culture of the corporation
IC
The researcher feels that older workers are not as highly valued as younger
workers in terms of their potential usefulness after retraining The researcher
searched the literature but found nothing in the existing literature to measure
the cultural value construct What should the researcher do to establish a reliable
and valid self-administered paper and pencil measure of this construct namely
the value of retraining older workers
a Please describe and explain the steps in temporal order that the researcher
must follow to develop a measure
b How would you evaluate the measure based on the technical requirements of
reliable and valid measurement as well as any practical issues in using the
measure considering the size of the employee population
B7 Assume that you are going to conduct empirical research to assess the role that
the complexity of an organizations manufacturing technology plays in
determining the level of centrality of decision making in the organization
Describe and justify the steps you might follow to develop an operationalization
of the concept of technological complexity What standards would you use to
determine if your operationalization is valid
B8 Organizational researchers have several strategies available to them for
gathering information (eg self-report measures archival measures direct
observation and trace measures) Assume that you are going to conduct
empirical research to assess the role that the structure of the organization plays
in determining the level of organizational effectiveness Briefly review the
strengths and weaknesses of the basic strategies (that is self-report measures
archival measures direct observation and trace measures) for measuring
organizational effectiveness Next describe and justify the steps you would
take to develop an operationalization of the concept of organizational
effectiveness What standards and procedures would you use to determine if
your operationalization is valid
B9 One of the most important topics of recent research has been stress in the work
place One of the most important problems with understanding this literature is
the varying definitions and measurement of this construct Suppose you had
decided to investigate the relationship between stress at the work place and dual
career family happiness
a Since there are multiple ways to measure stress in the work place describe
two ways to do this Hint - avoid using two self-report measures
b Describe how you would decide on the best single measure In doing so
describe the steps you would take in evaluating your measure Be sure to define
your meaning of validity and reliability It is important that your measure have
all the necessary psychometric characteristics so that other scientist can trust the
results of your research
c Be certain that you answer the question Validity for what
d In order to understand the results of your study you need to compare your
measure of stress at work with other measures of this construct How would you
do that
B10 Assume that you have been hired by a national survey research company
Shash Inc to write items that will be used in a national survey of attitudes
toward capital punishment There are a number of criteria that can be used to
guide your item writing What are they Briefly describe five (5) such criteria
B11 Assume that you are going to conduct empirical research to determine the
impact of interpersonal trust on organizational decision making Describe and
justify the steps you might follow to develop an operationalization of the
interpersonal trust concept
B12 Assume that you are going to conduct empirical field research to assess the role
that employee empowerment plays in determining the level of organizational
commitment of employees Describe and justifyexplain the steps you would
follow to develop a valid and reliable operationalization of the concept of
employee empowerment
Explain the procedures and standards you would use to determine if your
operationalization is valid and reliable
How would you assess the construct validity of such a measure
Discuss issues concerning the level of observation of your measure and level of
analysis of the data
B13 Assume you are interested in developing a new scale to measure construct X
Further assume that you have used previous literature and your own conceptual
development to delineate 2 dimensions of X specifically XF1 and XF2
Describe the steps you would go through in developing testing and evaluating
this new scale With regard to testing and evaluating be sure to consider the
role of factor analysis (both exploratory and confirmatory) and item analysis
Also you will want to make sure that your new multidimensional scale shows
evidence of validity (several kinds) and reliability so be sure to examine these
issues and explain how specific information gathered from the above testing
contributes to these concerns
C) Reliability
4) What is reliability and why is it so important What are the different ways reliability can be
assessed and when is each appropriate
15) What does coefficient alpha assess What are the ways coefficient alpha can be increased
C1 Describe and discuss the concept of reliability and all of its various forms
including their assessment When is each form appropriate and what information
is provided by each index
C2 In establishing congruence between multiple measurements we often compute
indices of reliability andor indices of agreement These two types of indices
address very different questions Your task is to 1) Define reliability and
agreement 2) Explain when each is useful using examples in which one but not
the other is appropriate and 3) Briefly describe two reliability indices and two
agreement indices
C3 Explain reliability in terms of the classical test theory What are the
consequences of unreliable measures in hypothesis testing What are the factors
that may affect the reliability of a multi-item scale
IC
C4 Generalizability theory is used within IO psychology more often today
However most researchers continue to use Classical Test Theory
conceptualizations of error to determine reliability What are the implications of
using classical test theory versus generalizability theory to assess reliability
C5 In establishing congruence between measurements we often compute indices of
reliability andor agreement Define reliability and agreement Explain the
differences in reliability and agreement and describe under what conditions
assessing reliability is more appropriate and under what conditions assessing
agreement is more appropriate
C6 Define measurement reliability in terms of a specific measurement theory (eg
true test score theory domain sampling theory generalizability theory IRT)
Discuss the different approaches for estimating reliability and the contexts in
which each might be appropriate Use examples throughout
C7 What are the consequences of unreliability in a measure
C8 What are some of the conditions that might keep the internal consistency (eg
alpha) of a given measure low Is a low alpha always a sign of a problematic
measure
C9 Define reliability Name some methods of calculating reliability How well do
these methods map up with the definition of reliability What is the impact of the
number of test items and sample size on Chronbachs alpha and why would this
effect occur or not occur (Note Do NOT discuss inter-rater reliability)
C10 Schmidt and Hunter (1996) described several types of measures typically used in
organizational research and identified the type(s) of measurement error affecting
each of them in various situations For each measure below indicate the types of
error and sources of error that are most likely to affect it Then indicate what
could be done to reduce errors of measurement andor what can be done to
control for errors statistically
a Supervisor ratings of subordinates job performance
b Self-ratings of ones own job performance
c Self-reports of ones own job-related attitudes
d Sales figures for a salesperson (or production quantity for a production
worker)
d Aptitude tests taken as part of the hiring process
C11 Suppose you had conducted research on the relationship between organizational
commitment and rigidity of organizational structure in 200 firms Your measure
of rigidity was based on number of organizational authority levels and the degree
to which written organizational rules existed and defined role behaviors for
employees Thus an organization with a large number of organizational levels
and specific written policies defining appropriate role behaviors for employees
would score high on rigidity of organizational structure After analyzing your
data you find that there is a statistically significant negative correlation between
commitment and rigidity which is consistent with your hypothesis However the
reliabilities for your two measures are
(1) commitment = 23 (2) rigidity = 83
How should you interpret your results What could you do to fix this situation
Describe the specific steps (in order) you would follow to develop a more
reliable measure of commitment
C12 (a) Define the concept of reliability (of measures) in a clear concise and
accurate manner (b) Provide a formula that expresses the reliability of a measure
in terms of two components of variance ie total variance and the error
variance
D) Multi-level Assessment
D1 One of the major challenges for group-level research is the issue of aggregation of
individual data to the group level
(a) Under what conditions (eg types of data number of raters) should the various
interrater agreement and reliability methods be used (Rwg Kappa and Weighted
Kappa percent agreement average pairwise correlation ANOVA methods
(interclass correlation coefficient WABA)) What are the advantages and
disadvantages of each of the methods
(b) Explain the controversy between Frank Schmidt Larry James and others
regarding the differences between interrater agreement and interrater reliability
Who is right Do the differences matter in research practice
Defend your answers
(c) Review two articles from the organizational behavior literature that have had to
deal with aggregation issues Critique the methods the authors used to make
aggregation decisions
(d) Provide some advice to researchers regarding what they should do if interrater
agreement and reliability indices indicate that it is not legitimate to aggregate their
data
(e) Provide some ideas for avoiding the need to aggregate in group-level research
through creative research methods and measurement strategies
D2 Cross-levelmulti-level research is becoming more evident in the organizational
research literature This type of research raises many issues and presents many
challenges in terms of designing the research measuring variables and collecting
and analyzing the data Assume that you are interested in aggregating data (eg
from the individual to the group or from the firm to the industry) for one or more
variables What are the major issues you will need to deal with
D3 A researcher wants to measure organizational climate for continuous learning
Organizational climate is operationalized as a shared consensual aspect of the
organization -- the shared perception among employees that the organization values
and supports continuous learning Describe how you would measure organizational
climate in this case Specify (a) the level (ie individual group organization) at
which the construct exists (b) the level at which you would measure the construct
and (c) the procedures that you would use to establish that measurement is aligned
with theory (ie the construct validity of the measure)
E) General (Measurement)
E1 Studies in organizational behavior research often rely on single-item measures of
key constructs The use of single-item measures has long been criticized based
on the premise that single-item measures are unreliable However Wanous
(Wanous amp Hudy 2001 Wanous amp Reichers 1996 Wanous Reichers amp Hudy
1997) has recently argued that single-item measures can exhibit adequate
reliability Wanous based this conclusion on a procedure for estimating the
reliability of single-item measures using the classic formula for correction for
attenuation Subsequent studies have yielded mixed results regarding the
conclusions of Wanous (eg Loo amp Kells 1998 Nagy 2002) and the veracity
of the perspective advocated by Wanous remains in question Summarize and
assess the arguments for and against the use of single-item measures and
evaluate the procedure and evidence offered by Wanous regarding the reliability
of single-item measures Based on your assessment and evaluation develop
recommendations regarding the use of single-item measures in organizational
behavior research

E2 Ipsative measures have become prevalent in organizational behavior research
Ipsative measures ask respondents to answer questions relative to one another
such that the scores for all questions sum to the same constant for all respondents
Examples of ipsative measures include rankings Q-sorts and the allocation of a
fixed number of points (eg 100) across a set of response options Ipsative
measures may be contrasted with absolute measures which ask respondents to
answer questions independently from one another Absolute measures are
exemplified by rating scales using an interval or ratio numeric response format
The relative merits of ipsative and absolute measures have been debated for
decades (eg Cornwell amp Dunlap 1994 Hicks 1970 Johnson Wood amp
Blinkhorn 1988 Saville amp Wilson 1991 1992) yet the fundamental issues
underlying this debate have not been adequately addressed in organizational
behavior research For example measures of organizational culture and values
are often ipsative and some researchers advocate these measures over absolute
measures (eg Meglino amp Ravlin 1987 OReilly Chatman amp Caldwell 1991
Ravlin amp Meglino 1987 see also Rokeach amp Ball-Rokeach 1989) Review the
relative merits of absolute and ipsative measures Based on your review which
form of measurement is most appropriate and why Do your conclusions depend
on the construct being measured If so what types of constructs are best suited to
ipsative measures and what types are best suited to absolute measures Next
apply your conclusions to the measurement of culture and values in
organizations What specific arguments have been advanced in favor of ipsative
measures of culture and values How sound are these arguments Should ipsative
measures be used in the study of organizational culture and values If not how
can absolute measures of culture and values be developed that address the
concerns voiced by advocates of ipsative measures Provide a specific example
of the type of measure you would propose

facets of a concept Although such measures are prevalent and in some cases are
advocated (eg Law et al 1998 1999) they can present a variety of conceptual
and methodological problems Describe the specific problems associated with
measures that use items representing different facets of a concept Compare these
problems with the purported advantages of such measures Conclude by

E5 Suppose Roberta Von Eisenbrick is a researcher interested in the consequences of
AFFECTIVE CONFLICT (AC) in decision-making teams She gets access to a
variety of outcomes assessment committees at each of 87 different schools in
the Dallas Independent School District and gains permission to tape-record two
of their meetings (one in February and one in March) Such committees have
been formed to develop quantitative ways to track pursuit of school goals and
provide accountability to local and state governments These are often divisive
teams with heated meetings because what gets assessed is what usually gets
rewarded After both of these meetings the committee members each
fill out a short questionnaire that contains 20 Likert-type items measuring how
much AC occurred (eg People in our group often get angry with each other)
The individual scores are summed across items then averaged across team
members to come up with a group-level AC score for each of the 87 2
meetings The same procedures are followed for a 5-item measure of Group
Cohesiveness (GC) which is predicted to be reduced by higher levels of AC
Roberta also listens to every tape and from her expert judgment she rates each

it
c What is construct validity Discuss how the (un)reliability of the AC measure
could affect the conclusions one would draw from a study involving it and GC In

problems engendered by significance testing and why have these remedies not
been widely adopted

D) ModeratorsMediators
D1 Moderation and mediation provide different ways to model third variable effects
(a) Please define both of these terms (b) Sketch a conceptual model to show how
each relates to main effects (c) Using variables of your choice please write
hypotheses to reflect both (d) Explain how each is tested analytically
D2 Discuss moderators and mediators Provide an example of how (1) a moderating
variable influences the relationship between the independent and dependent
variable and how (2) a mediating variable influences the relationship between
the independent and dependent variable Describe how you would test for both
moderation and mediation using regression
D3 Many theories in organizational research predict that the effects of one variable
on another are moderated by a third variable Such moderator effects are
typically tested by entering the product of two variables as a predictor after
controlling for the two variables that constitute the product Several researchers
have pointed out that this product is often highly correlated with the squares of
the two constituent variables and have suggested that moderating effects may be
tested after controlling not only for the two constituent variables but also their
squares (eg Cortina 1993 Ganzach 1998 Lubinski amp Humphreys 1990
MacCallum amp Mar 1995) Discuss the strengths and weaknesses of this
approach as compared to methods that use only the product term and its
constituent variables Conclude with recommendations as to when and under
what conditions organizational researchers should test moderator effects with the
squares of the constituent variables in the equation

D4 Assume you are interested in studying relationships amongst three variables X
Y and Z Your first hypothesis posits Z as a mediator of the relationship between
X and Y Your second hypothesis posits Z as a moderator of the relationship
between X and Y Draw the figures depicting each of these hypothesized
relationships and describe (make sure to write regression equations) how you
would test each of these hypotheses
D5 The amount of time and effort that the average person pours into his or her job
has risen steadily over the last two decades such that the average person now is
working one more week per year than the average person in the mid 1970s This
steady increase has fueled research interest in the construct of Job Burnout (JB)
which is an emotional and physical exhaustion associated with ones work
Organizational Stress (OS) the perception of greater demands than available
resources in ones work environment is thought to be one of the chief
antecedents of JB However time spent under OS is thought to make its affects
on JB accumulate or worsen Work Role Withdrawal (WRW) the avoidance of
responsibilities or the deliberate reduction of inputs to ones job is believed to be
the chief consequence of JB
a Formally state these ideas as verbal hypotheses as equations and as a complex
directed graph (circle amp arrow diagram)
b Conceptually what is a mediator Define the term and identify the mediator in
your hypotheses in (a) What elements or steps in a study design (not statistics)
that would be helpful for detecting the mediating relationship that was proposed

subdomains of management Further demonstrate your understanding of
moderator variables by picking which variable in (a) is the moderator Show the
moderating relationship in an X-Y (or multi-layered) chart Again what elements
or steps in a study design (not statistics) would be helpful for detecting the
moderating effect implied above

recommendations You conduct a well-designed controlled study (details are unimportant) and discover students who use the new book perform 10 better on a standardized subject
matter exam than those using the old book (p = 027) Both books are readily availabe their prices are almost identical and both are equally acceptable to the instructors What is your recommendation to the chair
F1 Attached is the beginning of an article Your task is to write the results section by
1 making up and reporting plausible descriptive statistics that will help the
reader understand the results of the statistical tests you report and the nature of your
sample (Hint this can be presented in the form of a table)
2 describing and defending your choice of appropriate statistical tests of the
hypotheses and the steps that you would go through in carrying out these tests
3 making up and reporting results of these tests that are consistent with your
descriptive statistics and with any information in the rest of the article about the
results found (Hint this can be presented in the form of a table)
4 describing how well these results provide support for the hypotheses You
may want to note any relevant threats to validity here
Be sure to state any assumptions you make
F2 Assume that the Personnel Manager of a local firm Ms B dFlandres hired you to
analyze some data that her assistants had collected over the past several years The
data consist of (a) job performance ratings that were made in June of 1990 and (b)
scores on 25 predictor variables (eg measures of education job experience job
tenure job aptitude personality) that were measured when the individuals were hired
(between April 1987 and May 1988) She had data from only the 110 subjects (60
males and 50 females) who were hired during the period and were still employed by
the firm One objective of your analysis (analyses) is to determine how well the
performance criterion can be predicted by the predictors What strategy would you
use in analyzing the data Describeexplain (b) Is sample size an issue for your
analyses Explain If it is what will you do to deal with problems stemming from
sample size Assume that no additional data can be collected at this time (c) Some
preliminary analyses that you do reveal that five of the predictor variables correlate
(zero-order basis) about 75 with one another Will this influence the analyses that
you use Will it influence the validity of conclusions derived from your proposed
analyses (d) Ms dFlandres is interested in knowing if the predictor variables are
equally effective in predicting the job success of males and females What analysis
or analyses would you do to deal with this issue
F3 Assume that you have been provided with data on 12 conceptually distinct variables
that are moderately correlated with one another at the empirical level The data are
from students in four different college majors ie astronomy (A) biology (B)
criminology (C) and demography (D) The 12 measured variables fall into the
general categories of mental health (tension emotional withdrawal hallucinations
guilt feelings blunted affect and suspiciousness) and job satisfaction (work itself
supervision co-workers pay promotion prospects and working conditions) Your
task is to determine if the individuals in the four college majors differ from one
another on the 12 measured variables
(a) What statistical technique(s) would you use to test for group differences
Explain Be specific about the procedures(s) that you would use
(b) What statistical estimate would you use to estimate the extent to which the
groups differ from one another Be specific
F4 The following statistical table published in a recent issue of Work amp Occupations
was taken from an article discussing variables influencing resistance and citizenship
behaviors in the workplace Resistance behaviors include playing dumb withholding
effort work avoidance subverting particular managers and sabotage Citizenship
behaviors include cooperation engaging in peer training use of insider knowledge to
facilitate production commitment to organizational goals giving extra effort freely
Both measures are global constructs aggregated to the interval level and
standardized
The table reports the results of a series of ordinary least squares regression equations
with standardized coefficients Explain the meaning of the statistics presented What
do these statistics tell us generally about the relationship between resistance
behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows
Anomie Index -standardized interval level measure tapping multiple dimensions
The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)
F5 Researchers collected data from a sample of 350 companies on the following
variables
size (measured as number of employees)
Business Strategy (a nominal variable with 2 response options low-cost provider or
differentiator)
HR Strategy (a nominal variable with 2 response categories High commitment or
low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

exploratory way Also describe the difference in principal components analysis
(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression

P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation

Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)
Please comment on these restrictions versus access argument Which side do you
take
What are the strengths of SEM Give some examples
What are the weaknesses of SEM Give some examples

a Construct a regression model that will test the researchers hypothesis Be
explicit here describing each variable in the model and what regression effect(s)
you would expect to find if the hypothesis were correct (Hint everything you need
to know is in Trochims chapter 11 and what we discussed in class) (10 points)
b Describe any serious threats to internal validity (10 points)
c Discuss how you might amend this design to improve its internal validity(10
points)
G6 Often in organizational research the researcher is faced with having only one group
on which to experiment and thus cannot use a control group when conducting
experiments This occurs for example in taxation experiments when you cannot
selectively apply new tax laws to different groups or when you wish to test the
efficacy of an incentive plan that must be applied to all members of a company In
such situations the researcher must be creative in assembling a quasi-experimental
design that has high validity (and usually the challenge concerns internal validity)
Consider the following scenario
A manager of a retail store wants to test the efficacy of an incentive program in
changing the selling behaviors of her retail sales clerks Specifically she wants to
test a behavioral reinforcement program in which sales peoples behavior is
recorded on in-store video cameras The tapes are analyzed each night and the
experimenter tabulates the frequency of various behaviors (eg offering assistance
to customers restocking items straightening up displays suggesting accessory
items to accompany the items that a customer is purchasing) The manager then
rewards the clerks with a monetary bonus based on the frequency of desired
behaviors She would like to conduct a valid experiment to see what effect such an
incentive program has on employee behavior but because of concerns about
employee morale she cannot assign clerks to treatment and control groups Instead
she has to apply the experimental treatment to everyone in the store She learned in
her research methods class (which the company requires all its managers to take)
that a single group experimental design typically has very low internal validity
Your job as a consultant is to help her design an experiment given her constraints
that would produce interpretable (ie internally valid) results Describe the details
of the design you would recommend using the notation in Trochim (2001) If the
design you come up with has a specific name use it As part of describing your
design discuss how the data would be analyzed and what particular effect you
would look for
G7 Why are experimental research designs held in such high regard
G8 Compare and contrast experimental quasi-experimental and correlational research
designs What characteristics separate these three designs What are their
advantages and disadvantages especially in comparison to one another
G9 What is the difference between a within-subjects experimental design and a
between-subjects experimental design When might a within-subjects design be
appropriate When might it be inappropriate
G10 Describe the difference between a basic within subjects and between subjects
experimental design What are the advantages and disadvantages of each
especially in comparison to one another Give an example from your area of
research in which each would be appropriate
G11 What are the major threats to the internal validity of a pretest - post test
nonequivalent control group design How can this design be improved with regard
to increasing a researchers ability to make causal inferences
G12 A production manager is interested in testing the hypotheses that participation in
quality circle programs will result in increased productivity and reduced
absenteeism A questionnaire is administered to a group of 92 employees
concerning their attitudes toward such programs and 46 with the most favorable
attitudes who are willing to participate are selected for the treatment group The
remaining 46 are the control group Measures of performance (unitsmonth for the
group) and absenteeism (lost daysmonth for the group) are kept over a three month
period during which the treatment group has weekly quality circle meetings The
results are as follows
Month 1 Month 2 Month 3 Month 1 Month 2 Month 3
Performance Absenteeism
Treatment 100 115 121 6 9 4
Control 110 108 113 6 8 5
The manager calculates t tests between month 1 and 3 The only significant
difference is performance for the treatment group so the manager concludes that
quality circles raise productivity but do not have an effect on absenteeism What
are the primary threats to internal and external validity in this study What are
possible alternative explanations for the differences (or lack of differences)
between the two groups What additional information might help explain these
results
G13 One stream of current strategy research contains event studies In these studies
investigators basically correlate the reaction of a financial market to the presence
andor absence of the occurrence of some event at a firm (eg the resignation of a
CEO) In a different approach to such a study suppose that one investigator (Jean)
conducts a natural field experiment on the effects of competitor mergers on a
firms environmental scanning activity Through previous arrangement Jean has
been working with 5 medium-sized computer hardware and 5 medium- sized
software firms on the west coast Shes been collecting a paper trail of internal
memos reports and phone calls that might measure environmental scanning
activity Shes been finding that the firms in both industries do about the same
amount of scanning (no significant differences) However in the midst of her data
collection Norton announces a merger with Symantec (software) A year later
Jean compares the amount of post-merger environmental scanning in the software
industry with that in hardware industry Just as Jean had hypothesized a t-test
shows a greater amount of post-merger scanning among the software firms She
concludes that her hypothesis was supported mergers of competitors cause an
increase in scanning
Critique the study described above in terms of its design flaws Identify the design
Jean used Briefly allude to problems the study has with external validity but
concentrate on the Cook and Campbell threats to internal validity Provide a
rationale for why each threat is or isnt operating in the study Link each of the
relevant threats to the specific constructs being studied (mergers and environmental
scanning) Finally do a summary evaluation -- what can be learned from this
study
H) Quasi-Experimental Design
H1 The University of Mississippi observed that the graduation rate of students with poor
grades during their freshman year was much lower than those with better grades
Wanting to improve the chances of these low performing students they tested the
effects of a new rule for freshmen The rule stated the following At the end of their
first semester all students with a GPA between 200 and 225 must register for
EDUC 1003 during their second semester Students with a GPA lower than 200
were put on academic probation EDUC 1003 consisted of a course whose objective
was to help students develop good study skills The theory was that poor study skills
were a significant cause of poor academic performance and that study skills could
be learned
They wanted to evaluate the effectiveness of this intervention so they collected data
on the GPAs of students beginning with their first semester and continuing through
to their third semester At that point they wanted to analyze the data to determine
whether the new rule was making a significant difference in the students academic
performance
What is the best way to analyze these data to reach an interpretable conclusion
Describe your approach and then discuss the major threats to validity that it has
Their sample size of students was as follows
Total N= 3454 (these are students who completed all 3 semesters)
Number of students with first semester grades between 200 and 225 (and thus took
EDUC 1003) was 956
H2 A nationwide furniture company wants to determine if a diversity training
program will improve individual sales performance on the floors of its urban retail
outlets A group of 45 salespeople in one city were given two weeks of training
Measures of individual sales performance were taken once two months prior to the
program and once two months after Forty-five salespeople (who did not receive the
training) in a similar city had the same measures taken at approximately the same
points in time The training group increased their average weekly sales from $14000
to $16500 while the non-training group improved theirs from $13000 to $14500
The change for the training group is statistically significant the change for the non-
training group is not
How would the interpretation of these results in this quasi-experimental design
differ from a true experimental design What are the threats to internal validity in
the above study and how might they be operating (be specific) What additional
information and analyses would be useful in controlling for these threats
H3 An accounting firm is interested in determining if a re-training program will reduce
errors made by its audit teams A group of 45 auditors in the home office location
are given two weeks of re-training Measures of the frequency of detectable errors
are taken once two months prior to the program and once two months after Forty-
five auditors in similar office at a branch location have similar measures taken at
approximately the same points in time The training group reduced their average
number of errors per audit from 8 to 3 while the non-training group reduced theirs
from 11 to 9 The change for the training group is statistically significant the change
for the non-training group is not
How would the interpretation of these results in this quasi-experimental design
differ from a true experimental design What are the threats to internal validity in
the above study and how might they be operating (be specific) What additional
information and analyses would be useful in controlling for these threats
H4 Describe the main classes of threats to validity that are found in quasi-experimental
research designs
H5 Dr Delta an organizational development consultant was hired by a firm that has
600 pizza parlors nationwide to assist in implementing organizational changes that
he hopes will result in higher levels of job involvement At the outset of the study
subjects had jobs with very low levels of enrichment and were paid on an hourly
basis He designed an experiment in which stores were randomly assigned to one of
three treatment conditions Condition 1 subjects experienced job enrichment (JE)
and a change to performance-based pay (PBP) Condition 2 subjects experienced
only JE and Condition 3 subjects experienced only PBP The parlors were
sufficiently far apart from one another and communication among the parlors so
poor that subjects in any parlor were totally unaware of changes made in other
parlors At the end of 18 months he measured the job involvement levels of workers
and then tested for differences between the three conditions using a standard one-
way analysis of variance In view of Dr Deltas design answer the following
questions
How sound is Dr Deltas design Comment on the weaknesses of the design
I) Interrupted Time Series Design
I1 What threats to internal validity are and are not ruled out by an interrupted time series
design that includes the introduction of a treatment and its removal at a subsequent
time period List and explain In the process be certain that you provide a diagram
that illustrates such a design
J) Validity Some Questions are about the validity of a measure others about experimental validity)
10) Identify four threats to internal validity and briefly describe what they mean
J1 It was some time ago that the tripartite view of validity was abandoned in favor of a
unitarian view in which different evidentiary bases for validity might be put forward
Binning amp Barrett (1989) represent an attempt to place multiple evidentiary bases into a
single framework Cook amp Campbell (1979) describe four aspects of validity but they
arent really meant to represent evidentiary bases Adding to the confusion is the fact
that while Binning amp Barrett and Cook amp Campbell use some of the same terms these
two pairs of authors clearly mean different things by these terms and intend for them to
be used in different ways Your task is to 1) Describe the evidentiary bases discussed
by Binning amp Barrett 2) Describe the aspects of validity described by Cook amp
Campbell 3) Describe the similarities and differences between the two lists including
the different purposes served by the two lists and 4) Present a single framework that
incorporates both This last task is the most important of the four
J2 What are the types of validity How would each affect an empirical study IC
J3 Define both internal and external validity Which is more important (it is not okay to
say that they are equally important) Defend your reasoning
J4 Why might someone argue that the construct validity of a measure can never really be
established
J5 Describe each of the following forms of validity content convergent discriminant
criterion-related and construct How is each assessed How do they related to each
other Which is most important (Make sure you defend your answer)
J6 Define and explain 6 of the 8 types of validity listed below and describe the type(s) of
information each provides Choose one specific type of study as an example (eg
cross-sectional study experiment quasi-experiment simulation ethnography etc) and
compare and contrast the usefulness and importance of each type of validity for that
type of study
-- Concurrent validity
-- Construct validity
-- Content validity
-- Convergent validity
-- Discriminant validity
-- Statistical conclusion validity
-- Internal validity
-- External validity
J7 Designing empirical research has been called making a series of trade-offs
Unfortunately decisions that are made to increase one desired quality (like internal
validity) can also decrease another desired quality (like external validity) For each of
the issues below discuss the concerns involved (ie the trade-off) and identify the
qualities that are being increased or decreased
a laboratory vs field study
b using a 5-item measure vs a 1-item measure
c using a student sample vs a sample of full-time employees
d using a sample of employees from one company of 5000 vs 500 employees from
each of 10 companies
e collecting your data using one method vs collecting your data using multiple
methods
J8 There are four major types of validity in social science internal validity external
validity construct validity and statistical conclusion validity Please address the
following three issues concerning validity
a What is the meaning of the four major forms of validity (ie internal and external
validity construct validity statistical conclusion validity)
b Are there trade-offs that can or must be made among the four types of validity
d Describe how the concept of validity varies across the research traditions of
experimental vs observational research
IC
J9 The quality of research is often assessed by examining validity issues As you are
aware there are numerous typesforms of validity (eg internal and external validity
construct validity statistical conclusion validity) These types of validity address
different aspects of the research process For this question please address the following
issues
a What is the meaning of the four major forms of validity (ie internal and external
validity construct validity statistical conclusion validity)
b Should there be a priority among these forms of validity If yes why If no why not
c Does the concept of validity vary across research traditions (ie experimental vs
observational research) If yes why If no why not
J10 External validity has received considerable attention in the social and behavioral
sciences Some researchers argue we are too concerned with the external validity of our
findings while other researchers argue that we are too unconcerned with external
validity Several points of view have been developed to explain what is external
validity When answering this question please be sure to address at least the following
issues
a Compare and contrast alternative conceptualizations of external validity
b Some researchers have argued that the role of external validity is invariant across
research traditions (ie experimental vs observational research) Defend the
perspective that the role external validity is invariant across these two research
traditions In addition present the weaknesses of this perspective
J11 In designing a research study researchers must consider trade-offs between internal and
external validity Explain what is meant by internal validity and external validity What
is the nature of these trade-offs How would you evaluatedetermine which is more
important internal or external validity for a particular study Why is this such an
important issue in organizational studies
J12 A researcher conducted a quasi-experiment to test the effects of participative decision
making (PDM) on job attitudes of employees Employees from different departments in
a large organization were assigned to either a treatment group (PDM implemented) or a
control group (no PDM) Random assignment was not possible because of work
schedules coordination of tasks etc Thus the design can be considered an untreated
control group design with pretest and posttest and is represented as follows (where
O=observation X = treatment)
________________

The results of the experiment are presented in the graph below [no graph provided]
The dependent variable is job satisfaction and is measured on a 100 point scale (with
100 being extremely satisfied) How amenable are these results to causal interpretation
What is (are) the major threat(s) to internal validity B if any B for this type of design
given these results What steps can be taken to assess the extent of this (these)
threat(s)
K) Data Collection Methods
14) Describe the various methods of data collection (eg survey interview observation etc)
available to a social scientist What are the advantages and disadvantages of each relative to
each other
K1 Within micro organizational research much criticism has been raised concerning
the reliance on self-report survey data What potential problems does self-report
survey research raise How big of a problem do you think this is
K2 There are a number of methods for collecting data (eg survey interview archival
etc) that are available to a social scientistorganizational researcher Discuss each in
terms of their strengths and weaknesses both on their own and in comparison to one
another
K3 Pick an important construct in your favorite area of management research for which
there is some controversy about how it should be measured or operationalized (eg
environmental munificence or growth need strength) Give the prevailing verbal
definition of the construct and analyze the measurement controversy from two
broad angles First discuss how the controversy may or may not stem from claims
about how one measure is better or worse than another because it (or the other) is an
(a) archival record (b) direct observation (c) social report or (d) self-report That is
what are the relative strengths and weaknesses of each of these types of
measurement for the construct youre discussing Second discuss the construct
validity of the most commonly used measure(s) of this construct To answer this
second part you need to discuss just what construct validity is and how it can or
cannot be demonstrated In the situation you describe what could be done to
demonstrate or improve the construct validity of existing measures
K4 Interviewing in some form has been the workhorse for data collection in a variety
of research traditions positivistquantitative ethnographic feministpost-modernist
and increasingly historical research While each tradition elicits information from
respondents the goals and processes involved in interviewing vary considerably
across research traditions Discuss the purposes of the interview the relationship
between data and theory the roles assumed by the interviewer and the respondent
and the relevant criteria for assessing the validity and reliability of the information
obtained In addition compare and contrast the use of the interview as a data
collection method in the positivistquantitative tradition with its use in one of the
alternative traditions
L) Common Method Variance
L1 Many of us have had concerns about the reviews of our survey research which
suggest that data analyses of surveys are biased because of common method
variance effects of individual differences such as negative mood negative
affectivity and social desirability and the reliability and validity of the constructs
we are attempting to measure Define how these problems affect a research issue in
organizational behavior and the steps that might be taken to minimize such potential
criticisms of papers based on analyses of self-reported data through survey
instruments
L2 In a series of papers by Spector (1994) Schmitt (1994) and Howard (1994)
published in the Journal of Organizational Behavior arguments were provided for
and against the use of self-report questionnaire measures One of the issues
discussed that could limit conclusions drawn from relationships observed using self-
report measures was method variance What is meant by method variance what are
its sources and what impact is it expected to have on research findings
M) Sampling
M1 The manufacturing census samples all plants of 250 employees or more For
plants of 5-249 employees it takes a size proportional sample Plants of 1-4
employees are not sampled What challenges does this sampling method provide
to researchers What could you do to account for these problems if you were
TH
studying organizational (not plant) growth
M2 New York State has approximately 250000 employees in over 70 state agencies
commissions and boards ranging in size from approximately 50 to over 5000
employees Assume that you wanted to draw a representative sample of 1000
employees Describe two ways that you could draw such a sample and briefly
describe the advantages and disadvantages of each of these sampling approaches
IC
M3 The director of a national non-profit agency with approximately 10000
employees located primarily in regional offices in each of the 50 states the
United States has approached you and asked you to develop a study
(organizational survey) of organizational culture within the agency The agency
is about to embark on a variety of change initiatives including developing team
structures and the study is meant to examine various elements of organizational
culture that are potential barriers to change The director has indicated that he
would like to have the data analyzed at both the individual and office level of
analysis Because of funding limitations the agency will only be able to send the
survey to 1000 employees The director has indicated that there are three ways
of sorting employees all employees listed alphabetically all employees listed
alphabetically by state and all employees listed alphabetically by region (there
are between five and ten regions per state) Given these three ways of sorting
employees describe at least three different sampling approaches and the
advantages and disadvantages of each
M4 In your role as Teacher of Organizational Studies you are asked to prepare a
tutorial for beginning doctoral students on sampling design Assume that this
tutorial is part of a basic class in research design and that students in this class
have had a basic statistics course up to and including multiple regression Your
tutorial should focus on briefly defining and explaining the differences between
probability and non-probability samples You should make sure to present and
describe several types of probability samples (eg random systematic
stratified etc) and non-probability samples (eg convenience snow-ball quota
etc) and discuss general principles for when to use a probability vs a non-
probability sampling design For each sampling design you should also provide
at least one clear example of a situation where this type of sampling design is
appropriate
N) Cross-Cultural Research
N1 Discuss the problems in conducting cross-culturalnational comparison in terms
of (1) conceptualization and (2) research design and data collection
Define the three levels of measurement invariance How would the problems that
you have identified in part (a) affect measurement invariance How would you
examine measurement invariance by confirmatory factor analysis
TH
N2 Explain why using national boundaries as independent variable in cross-cultural
studies may not be appropriate in terms of theory and research methods What
alternative ways would you recommend
IC
O) General
O1 In your readings research has been described as choices among conflicting goals
(desiderata) For instance when choosing among research strategies a researcher
must choose among the desiderata of precision realism and generalizability The
trade-offs among desiderata occur for all aspects of research that is for the selection
of theories the treatment of independent variables research strategies the selection
of the problem to study rules of evidence for determining the meaningfulness of a
research finding and even the frameworks that describe the research process
Discuss what you see as the major trade-offs for each of the following aspects of
research That is discuss what you see as the major strengths and weaknesses
(advantages and disadvantages) of each aspect
a The trade-offs between internal and external validity
b The manipulation of the independent variable vs the observation of the
independent variable
c Basic vs applied research
3 DESIGNING A RESEARCH STUDY
A) General (Research Design)
3) Why is control so important in research design What are the different ways it can be
achieved (give a brief description of each control method) What are advantages and
disadvantages of each
A1 It has become almost a truism to note that the choice of methods influences theory
and questions data and conclusions (the causal direction might also be reversed)
Briefly discuss how the methods used have influenced research in any two of the
following areas leadership power and politics organization culture organization
justice Compare and contrast as possible Suggest some potentially fruitful
methodological directions for future work in these same topical areas and dont be
shy about reflecting on broader issues of how the field of organizational behavior
constructs its realities Lastly tie your discussion and reflections back to your own
future as a researcher what lessons or guidance do you derive from your
understanding of these issues
A2 Characterize as fully as possible what you see to be the methodological approach or
approaches in strategic management research Is there a dominant method or a wide
variety Discuss the reasons for the situation What are the advantages benefits etc
of the approach(es) in use What assumptions (ontological epistemological
ideological) do they embody Are current efforts ideal or at least adequate Are
there other approaches that could be useful If so how might researchers be
encouraged to use these as well If you see no advantage to more variety in
methodological approach support that point of view
A3 Describe a research question or area of interest to you and why you think it is not
only of interest but significance Using your understanding of research methodology
describe two ways of pursing the question that are as divergent on as many
dimensions as you can imagine Describe the advantages and disadvantages of each
approach How strong a link or fit is there between a research question and a
method
A4 In his 1957 article entitled The two disciplines of scientific psychology Cronbach
discussed the assumptions goals and methods used in experimental methods and
correlational methods in psychology
a According to Cronbach what is the main difference between the two disciplines
b Discuss the strength and weaknesses of each discipline
c What if anything could be done to improve the situation
B) Designing a Research Study
B1 Cook and Campbell describe the experiment as the research design with the
greatest methodological rigor However given the constraints present in most
organizations I-O Psychologists cannot often conduct experiments in applied
settings and must settle for techniques with less control than experiments
Describe a study to investigate the relationship between participation in a
supervisor training program and work performance which could realistically be
conducted in an organization If an experiment is not possible describe how you
would go about maximizing your ability to draw valid conclusions from your
design
B2 The XYZ Co has recently developed a sexual harassment web-based training
program The developers claim the program will cut training time and costs and
will be as effective or more effective than classroom-based sessions They
believe that this will be due to the increased availability of the program and the
ability for participants to review program material on demand Before the XYZ
Co developers launch this product they want you to determine if their claims
have merit Explain how you would design a study for this purpose
B3 Research suggests that demographic diversity improves group creativity but
reduces group efficiency Some argue that demographic diversity is just a proxy
for value and experience diversity and that demographic diversity on its own is
meaningless Design a test to settle this argument
TH
B4 E-mail has become a common form of communication in organizations and is
used for both formal and informal communication Because it has become so
IC
popular some people complain that the frequent use of e-mail leads to
miscommunication because they receive communications in e-mail that should
be accomplished through face-to-face or telephone conversations where there is
an opportunity for interaction You are interested in looking at this
phenomenon You are most interested in describing how e-mail is used for both
formal and informal communication and in examining the effect of the e-mail
use on organizational communication effectiveness Design empirical research
to address those issues
Describe your study in detail thoroughly explaining the research design
sampling plan data collection procedures ethical issues and proposed data
analysis for your research design Be sure to discuss the internal and external
validity of your research Which validity threats are ruled out and which
remain
REMEMBER Be thorough Your research design should demonstrate that you
are a competent researcher who is knowledgeable about the proposed research
methodology or methodologies Therefore be sure that you carefully describe
and give technical explanations for each component of your research
B5 Choose a specific situation involving employee selection eg artists for an
advertising agency (a) What strategy would you use in selecting the selection
measures (b) How would you combine the measures eg which measures
would you combine in a compensatory manner and which is a noncompensatory
manner (c) How would you assume test fairness defining various measures of
the term (d) How would you make final selections (e) How would you
validate your procedure (f) What considerations would enter in if your
company were too small to provide validation data (g) What difference would
it make if you were developing a procedure for deciding whether trainees
should be promoted as opposed to making new hires Please note--emphasize
but do not limit yourself to statistical issues
B6 There is evidence in the marketing literature of a non-monotonic relationship
between the expectations that customers have for retail service and their
eventual level of satisfaction with that service That is as a customers
expectations for service increase so does their eventual service satisfaction --
up to a point After that point the greater the expectations the lower the
eventual satisfaction Develop a hypothesis that includes a moderator variable
that might account for this evidence Give some reasonable rationale for it State
your hypothesis verbally as an equation as a directed graph (circle amp arrow
diagram) and as an X-Y function chart Discuss how it would or would not be
possible or useful to test your hypothesis via a laboratory experiment In your
discussion cover how and why a researcher could (not) manipulate the
independent constructs involved (mode X) whether or not random assignment
to conditions (mode R) is possible (including how may conditions would be
necessary) which alternative constructs could or could not be controlled (mode
K) and which constructs should be measured (mode Y)
B7 Assume you are the chairperson of a committee that must evaluate
undergraduate programs at your university Your task as chairperson is to
devise an approach (a design a research strategy a set of measures) that will
allow you to evaluate undergraduate programs Make sure that your approach
can be used in the future and at other comparable universities When developing
your plan be sure to address at least the following issues
a the type of design you would select Compare and contrast the selected design
with another possible design
b the type of research strategy you would select Compare and contrast with
another possible strategies
c discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
B8 Assume you are an organizational research design expert assigned to the
Strategic Planning Department of a large multi-national manufacturing firm
The Department has developed a new PC-based software package called
STRATPACK The software (and a one-week training course to learn how to
use it) is intended to improve the long-range planning ability of middle and
upper-level managers
Your job as research design expert is to devise research (a design a research
strategy a set of measures) that will allow you to evaluate the effectiveness of
the STRATPACK program Describe a research design for evaluating the
program Make sure that your research approach can be used in the future and at
all sites in the company When developing your plan be sure to address at least
the following issues
a discuss how your design and approach deals with the major forms of validity

independent variable versus observe the independent variable) Compare and
contrast the selected design with another possible design
c how your design deals with the major forms of validity Be sure to examine at
least internal external and construct validity
B9 Assume you are a consultant hired to evaluate the effectiveness of an industrial
safety program undertaken by a large manufacturing organization The safety
program is a behavioral one that provides rewards such as monetary bonuses or
extra paid vacation days for safety behaviors in terms of accident-free days
weeks etc Your task is to devise an approach (a research strategy a design a
set of measures and a general analysis strategy) that will allow you to evaluate
the safety program Because of the potential for the influence of many
extraneous variables on any safety program it is difficult to design research a
single cross-sectional study than can evaluate the impact of a single safety
program How would you design a study to evaluate the impact of the safety
program When developing your plan be sure to address at least the following
issues
a the type of research strategy you would select Compare and contrast with
another possible strategies
b the type of design you would select Compare and contrast the selected design
with another possible design
c discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
B10 One of the most important areas of research is forecasting of human resources
needs based on strategic positions of organizations For example NY State must
carefully forecast its human resources needs as it proceeds with significant lay-
offs of state employees Future human resources needs are generally evaluated
by either statistical ie regression or simulation or clinical judgment i e
supervisors judgments methods
a Design a single study that addresses the empirical question of whether
statistical or judgmental methods are better for forecasting human resources
needs You may discuss a program of research but please be quite specific in
your description of the first study
b What are the critical methodological issues in doing this kind of research
c What are the critical applied (or practical) issues in doing this research
d Are the issues in b and c related
B11 In the past decade computinginformation technology has changed many
aspects of organizational life For example the technology can make increased
decentralization possible by improving communication between central offices
and field offices Computer networks and word processors can enhance group
empowerment by making it possible for team members to create and edit
written group products quickly even if the individuals are at different locations
Some have argued that computinginformation technology will foster the
paperless productive office nevertheless others argue that the technology only
increases paper and reduces office productivity You are applying to the
National Science Foundation for a grant to conduct research that examines the
impact of computing information technology on organizational decision
processes The NSF application procedure imposes five basic requirements that
your research design must fulfill in order to receive funding Note A very
significant factor affecting NSF grant decisions is a clear demonstration that the
researcher is knowledgeable about the research methodology used Write your
response to each of the following five grant requirements Be sure not only to
respond to the requirement but also to demonstrate your research
competence
1You must design a study that uses two different methods
(interviewobservation survey experiment or quasi-experiment) Describe your
two methods in detail and provide a rationale for the key elements (eg
sampling data collection proposed analysis) of your methods Be sure to
discuss and evaluate the internal and external validity of both methods
2 As part of your research design you must select a conceptual (latent) variable
central to your proposal (use centralization of decision making as your
variable) and describe how you will develop your own measure (You may not
simply use off the shelf instruments)
3 You must describe how you will test for the reliability of the measure
(centralization of decision making) you developed in step 2 The NSF insists
that you describe how you will evaluate both the temporal stability and the
internal consistency of your measure Be sure to discuss what temporal stability
and internal reliability mean and how they are related
4You must describe how you will assess the validity of the measure
(centralization of decision making) you developed in step 2
5 NSF requires a brief statement and defense of the philosophy of science
underlying your research Discuss your position and show how your research
design is consistent with your philosophy
B12 Many organizations in the United States economy have installed some form of
Empowered Teams as an alternative or supplement to traditional bureaucratic
structure Preliminary evidence of the effectiveness of empowered teams
however is mixed--some organizations have claimed success and others have
reported failures The evidence however is predominantly anecdotal--written
for trade magazines by the organizations themselves There are few rigorous
empirical studies assessing the effectiveness of empowered or self-managed
teams You are applying to the United States Department of Labor (USDOL) for
a grant to conduct research that examines the effectiveness of empowered
teams The application procedure of the USDOL imposes three requirements
that your research design must fulfill in order to receive funding Write your
response to each of the three grant requirements The importance of each section
is implied by the evaluation points allocated by the USDOL to each of the three
requirements given in parentheses
1 (50 points) Your study design for assessing Empowered Team effectiveness
must use two different methods (interview observation archival analysis
survey simulation experiment or quasi-experiment) Describe in detail and
thoroughly explain the sampling plan instrumentation data collection
procedures and proposed data analyses for both methods Be sure to discuss the
internal and external validity of both methods and how the two methods
complement one another
2 (30 points) As part of your research design you must select one conceptual
(latent) variable central to your proposal and describe how you will develop
your own operationalization of the measure (You may not simply use off the
shelf instruments) Use the concept of group morale to demonstrate your
operationalization methodology Be sure to explain very explicitly to the
USDOL how you will assess the validity and reliability of the group morale
measure you are developing
3 (20 points) The USDOL traditionally has funded research conducted only
within the general paradigm of logical positivism but now is more open to other
research paradigms as well Your grant proposal must provide a statement and
defense of the explicit philosophy of science underlying your research Describe
your philosophy of science and show how your research design is consistent
with your philosophy
REMEMBER Be thorough You not only must design effective research but
you also must demonstrate to the USDOL that you are a competent researcher
It is absolutely vital to the USDOL that the principal researcher is
knowledgeable about the proposed research methodologies Therefore be sure
that you always carefully describe and give technical explanations for each
component of your research design and explain all technical terms (eg
Cronbach alpha KR-20 Likert scale)
B13 Assume that you are working as part of a research team that is responding to a
RFP (Request for Proposals) from a funding agency for research on work
socialization and newcomer adjustment The RFP calls for rigorous field
research that tests the effectiveness of theory-based interventions aimed at
facilitating the adjustment of new organizational members to complex andor
stressful work conditions The major goal of your teams research is to test the
effectiveness of a self-regulation intervention which trains newcomers to
identify and use relevant social information and cues to regulate work behavior
Your group hypothesizes that self-regulation training will be more effective
than other common treatments or interventions (eg realistic job previews
institutionalized socialization tactics)
You have been included in the team because of your methodological expertise
Your role is to design a rigorous field experiment or quasi-experiment to test he
effectiveness of the self-regulation training program REMEMBER THE
MAJOR CRITERION FOR FUNDING IS THE RIGOR OF THE RESEARCH
DESIGN Design a field study to include in the grant proposal Your proposal
should contain the following two sections
1 Study Design Construct and describe in detail an experimental or quasi-
experimental design to test the effectiveness of your intervention Describe in
detail the experimental groups (including how they will be constructed) the
research setting the sampling plan for study participants the treatment
manipulation and the data collection procedures Also indicate any control or
nuisance variables that may be measured
After describing the procedures write a justification of the design What threats
to validity does it rule out or limit and what threats to validity remain
II Measurement Describe the steps you would take to achieve valid and
reliable measure of the latent (conceptual) variable worker adjustment Your
team feels that as part of the proposal you must develop an original
operationalization of adjustment (thus you cannot simply use existing off the
shelf measures) Indicate in adequate detail how you would operationalize the
measure and indicate how you would demonstrate reliability and validity
B14 In describing their notion of the collective mind Karl E Weick and Karlene H
Roberts note Our focus is at once on individuals and the collective since only
individuals can contribute to a collective mind but a collective mind is distinct
from an individual because it inheres in the pattern of interrelated activities
among many people (p 360) Collective mind is not indexed by within-group
similarity of attitudes ideas or activities A collective mind is one in which
many people or many groups integrate their different attitudes ideas and
activities heedfully As Weick and Roberts note People act heedfully when
they act more or less carefully critically consistently purposefully attentively
studiously vigilantly conscientiously pertinaciously (p 361)
The idea of the collective mind as heedful interrelating is developed in the
following excerpt When people make efforts to interrelate these efforts can
range from heedful to heedless The more heed reflected in a pattern of
interrelations the more developed the collective mind and the greater the
capability to comprehend unexpected events that evolve rapidly in unexpected
ways When we say that a collective mind comprehends unexpected events we
mean that heedful interrelating connects sufficient know-how to meet situational
demands For organizations concerned with reliability those developments
often consist of unexpected non-sequential interaction (p366)
An example of heedful interrelating occurs as a pilot lands herhis aircraft on the
deck of an aircraft carrier The pilot does not actually land She is recovered
A recovery is an interrelated set of activities among air traffic controllers
landing signal officers the control tower navigators deck hands the helmsman
driving the ship etc These activities can be interrelated more or less heedfully
depending on the care with which the different units contribute represent the
situation and subordinate their activities to the single purpose of successful
recovery (p 363)
You are to design a two-part study
Part I You are to design a measurement study which assesses heedful
interrelating (ie collective mind) with a quantitative measure in a replication
of an aircraft carrier flight deck or other situation of your choosing Describe
your research strategies including operationalization of the variable selection of
the sample subjects data collection data analysis and so on for the purpose of
developing a measure of heedful interrelating
Part II Using the measurement tool developed in Part I and any other tools as
needed describe how you would design a study which would compare heedful
interrelating across organizations Choose at least one macro-organizational
variable (eg technology environment) as your basis of comparison Here you
must describe how you would make your selection of organizations to be
compared your data collection procedure data analysis and so on
B15 Many organizations in the United States have installed cross-functional teams to
counteract the silo mentality of traditional bureaucratic structure Preliminary
evidence of the effectiveness of cross-functional teams however is mixed --
some organizations have claimed success and others have reported failures The
evidence moreover is predominantly anecdotal--written for trade magazines by
the organizations themselves Since there have been few rigorous empirical
field studies assessing the effectiveness of cross functional teams the National
Science Foundation has decided to fund research on the topic
Assume that you are submitting a research proposal to NSF for a grant to
research the effectiveness of cross-functional teams Describe in detail and
thoroughly explain the research design sampling plan data collection
procedures ethical issues and proposed data analysis for your research design
Be sure to discuss the internal and external validity of your research Which
validity threats are ruled out and which remain NSF also requires that you
provide a statement and defense of the explicit philosophy of science underlying
your research Describe your philosophy of science and discuss how your
research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but
you must also demonstrate to NSF that you are a competent researcher It is
absolutely vital to NSF that the principal researcher (you) is knowledgeable
about the proposed research methodologies Therefore be sure that you always
carefully describe and give technical explanations for each component of your
research design and explain all technical terms (eg Cronbach alpha KR-20
Likert scale)
B16 Assume that you are submitting a research proposal to the Department of
Commerce (DoC) for a grant to research the effectiveness of virtual work teams
A virtual work team is a leaderless collection of individuals who are
geographically separate from one another and share their expertise using
internet media such as a listserver or Lotus notes The DoC requires that the
researcher use both qualitative and quantitative methods to gather data Describe
in detail and thoroughly explain the research design sampling plan data
collection procedures ethical issues and proposed data analysis for your
research design Be sure to discuss the internal and external validity of your
research Which validity threats are ruled out and which remain The DoC also
requires that you provide a statement and defense of the explicit philosophy of
science underlying your research Describe your philosophy of science and
discuss how your research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but
you must also demonstrate to DoC that you are a competent researcher It is
absolutely vital to DoC that the principal investigator (you) is knowledgeable
about the proposed research methodologies Therefore be sure that you always
carefully describe and give technical explanations for each component of your
research

that improves upon the key validity (or validities)
5 MEASUREMENT
A) Measurement Terms
A1 There are four levels of measurement rigor in management research Discuss each
one What properties do measurements at each level have (ie how much
information do the numbers from each level of measurement convey) How can the
numbers be changed (transformed) and still retain the properties of their
measurement level Pick one construct from a favorite research domain and give an
example of an operationalization of that construct at each of the four levels of
measurement rigor (provide arguments about why you think those examples reflect
each level) Lastly treat each examplelevel as a dependent variable in some
statistical analysis Given an example of a statistical technique appropriate for
analyzing data at that level of measurement rigor
A2 Define (and discuss important features or issues concerning) the following
constructs measurement (Define any six terms)
1 Construct validity 6 Item analysis
2 Likert scaling 7 Semantic differential
3 Cronbachs alpha 8 True score
4 Unobtrusive (trace) measurement 9 Generalizability theory
5 Interval scale 10 Criterion-related validity
11 Sociometric choice measures
B) Operationalization
B1 a) You are conducting a study which requires you to measure Hong Kong real
estate agents self-assessment of performance Since there is no existing
measurement available you have to develop the instrument by yourself
Describe how you would develop the measurement assuming that you have no
idea of how many dimension the construct has
b) Suppose you have developed an instrument consists of 20 questions
measuring 4 dimensions (5 items per dimension) from (a) You collected data
from another 300 real estate agents to validate your instrument Explain how
TH
you would use structural equations model (SEM) to examine the reliability and
validity of the instrument What are other concerns about reliability and validity
that are not addressed by this approach
B2 The research and business world have been fascinated with the concept of
organizational culture However operationalizing this construct has been a
difficult task Discuss the ways in which the construct has been operationalized
(eg technique static v dynamic sample selection generalizability) Critically
analyze each of these methodologies Then choose a methodology you would
use to examine organizational culture and defend your choice Describe how
you would study culture and what more would be known about culture as a
result of your study
B3 Suppose you are setting out to develop a new measure of a construct You want
this measure to be used in survey research and you want to establish its validity
and reliability Your goal is to have at the end of the process a measure that is
defensible and likely to be widely accepted by other researchers studying that
construct What steps would you take to conduct such a program of research
For each step explain the purpose of that step explain why that step is
important explain what methods and statistical procedures you would employ at
each step and explain what evidence you would hope to gather at each step
B4 Assume you are interested in constructing a new measure of (fill in with a
relevant variable from your field) Detail the major concerns that need to be
addressed and the steps that need to be taken in working toward validating this
new measure
B5 Assume that you recently read an article on workplace violence which you
found very interesting The authors argued that one of the predictors of
workplace violence was a construct called propensity to be violent and used a
one-item measure as follows How likely are you to become violent when
provoked You had serious doubts about the authors measure and decided to
develop your own
(a) How would you go about developing items to measure propensity to be
violent
(b) How would you determine whether the instrument was reliable
How would you determine whether the instrument was valid
B6 A concern in organizations is retirement of baby boomers within the next 5 -
10 years This concern is focused on the loss of older employees with skills
critical to the core business functions of organizations In order to continue to
have employees with those critical skills it seems necessary to retrain some
older workers However past practice in most organizations has been not to
retrain older workers for a variety of reasons mostly financial A researcher
working for the Human Resources Department of a large corporation - 13500
employees in 12 different plant locations - hypothesizes that the major reason
for not retraining older workers is ingrained in the culture of the corporation
IC
The researcher feels that older workers are not as highly valued as younger
workers in terms of their potential usefulness after retraining The researcher
searched the literature but found nothing in the existing literature to measure
the cultural value construct What should the researcher do to establish a reliable
and valid self-administered paper and pencil measure of this construct namely
the value of retraining older workers
a Please describe and explain the steps in temporal order that the researcher
must follow to develop a measure
b How would you evaluate the measure based on the technical requirements of
reliable and valid measurement as well as any practical issues in using the
measure considering the size of the employee population
B7 Assume that you are going to conduct empirical research to assess the role that
the complexity of an organizations manufacturing technology plays in
determining the level of centrality of decision making in the organization
Describe and justify the steps you might follow to develop an operationalization
of the concept of technological complexity What standards would you use to
determine if your operationalization is valid
B8 Organizational researchers have several strategies available to them for
gathering information (eg self-report measures archival measures direct
observation and trace measures) Assume that you are going to conduct
empirical research to assess the role that the structure of the organization plays
in determining the level of organizational effectiveness Briefly review the
strengths and weaknesses of the basic strategies (that is self-report measures
archival measures direct observation and trace measures) for measuring
organizational effectiveness Next describe and justify the steps you would
take to develop an operationalization of the concept of organizational
effectiveness What standards and procedures would you use to determine if
your operationalization is valid
B9 One of the most important topics of recent research has been stress in the work
place One of the most important problems with understanding this literature is
the varying definitions and measurement of this construct Suppose you had
decided to investigate the relationship between stress at the work place and dual
career family happiness
a Since there are multiple ways to measure stress in the work place describe
two ways to do this Hint - avoid using two self-report measures
b Describe how you would decide on the best single measure In doing so
describe the steps you would take in evaluating your measure Be sure to define
your meaning of validity and reliability It is important that your measure have
all the necessary psychometric characteristics so that other scientist can trust the
results of your research
c Be certain that you answer the question Validity for what
d In order to understand the results of your study you need to compare your
measure of stress at work with other measures of this construct How would you
do that
B10 Assume that you have been hired by a national survey research company
Shash Inc to write items that will be used in a national survey of attitudes
toward capital punishment There are a number of criteria that can be used to
guide your item writing What are they Briefly describe five (5) such criteria
B11 Assume that you are going to conduct empirical research to determine the
impact of interpersonal trust on organizational decision making Describe and
justify the steps you might follow to develop an operationalization of the
interpersonal trust concept
B12 Assume that you are going to conduct empirical field research to assess the role
that employee empowerment plays in determining the level of organizational
commitment of employees Describe and justifyexplain the steps you would
follow to develop a valid and reliable operationalization of the concept of
employee empowerment
Explain the procedures and standards you would use to determine if your
operationalization is valid and reliable
How would you assess the construct validity of such a measure
Discuss issues concerning the level of observation of your measure and level of
analysis of the data
B13 Assume you are interested in developing a new scale to measure construct X
Further assume that you have used previous literature and your own conceptual
development to delineate 2 dimensions of X specifically XF1 and XF2
Describe the steps you would go through in developing testing and evaluating
this new scale With regard to testing and evaluating be sure to consider the
role of factor analysis (both exploratory and confirmatory) and item analysis
Also you will want to make sure that your new multidimensional scale shows
evidence of validity (several kinds) and reliability so be sure to examine these
issues and explain how specific information gathered from the above testing
contributes to these concerns
C) Reliability
4) What is reliability and why is it so important What are the different ways reliability can be
assessed and when is each appropriate
15) What does coefficient alpha assess What are the ways coefficient alpha can be increased
C1 Describe and discuss the concept of reliability and all of its various forms
including their assessment When is each form appropriate and what information
is provided by each index
C2 In establishing congruence between multiple measurements we often compute
indices of reliability andor indices of agreement These two types of indices
address very different questions Your task is to 1) Define reliability and
agreement 2) Explain when each is useful using examples in which one but not
the other is appropriate and 3) Briefly describe two reliability indices and two
agreement indices
C3 Explain reliability in terms of the classical test theory What are the
consequences of unreliable measures in hypothesis testing What are the factors
that may affect the reliability of a multi-item scale
IC
C4 Generalizability theory is used within IO psychology more often today
However most researchers continue to use Classical Test Theory
conceptualizations of error to determine reliability What are the implications of
using classical test theory versus generalizability theory to assess reliability
C5 In establishing congruence between measurements we often compute indices of
reliability andor agreement Define reliability and agreement Explain the
differences in reliability and agreement and describe under what conditions
assessing reliability is more appropriate and under what conditions assessing
agreement is more appropriate
C6 Define measurement reliability in terms of a specific measurement theory (eg
true test score theory domain sampling theory generalizability theory IRT)
Discuss the different approaches for estimating reliability and the contexts in
which each might be appropriate Use examples throughout
C7 What are the consequences of unreliability in a measure
C8 What are some of the conditions that might keep the internal consistency (eg
alpha) of a given measure low Is a low alpha always a sign of a problematic
measure
C9 Define reliability Name some methods of calculating reliability How well do
these methods map up with the definition of reliability What is the impact of the
number of test items and sample size on Chronbachs alpha and why would this
effect occur or not occur (Note Do NOT discuss inter-rater reliability)
C10 Schmidt and Hunter (1996) described several types of measures typically used in
organizational research and identified the type(s) of measurement error affecting
each of them in various situations For each measure below indicate the types of
error and sources of error that are most likely to affect it Then indicate what
could be done to reduce errors of measurement andor what can be done to
control for errors statistically
a Supervisor ratings of subordinates job performance
b Self-ratings of ones own job performance
c Self-reports of ones own job-related attitudes
d Sales figures for a salesperson (or production quantity for a production
worker)
d Aptitude tests taken as part of the hiring process
C11 Suppose you had conducted research on the relationship between organizational
commitment and rigidity of organizational structure in 200 firms Your measure
of rigidity was based on number of organizational authority levels and the degree
to which written organizational rules existed and defined role behaviors for
employees Thus an organization with a large number of organizational levels
and specific written policies defining appropriate role behaviors for employees
would score high on rigidity of organizational structure After analyzing your
data you find that there is a statistically significant negative correlation between
commitment and rigidity which is consistent with your hypothesis However the
reliabilities for your two measures are
(1) commitment = 23 (2) rigidity = 83
How should you interpret your results What could you do to fix this situation
Describe the specific steps (in order) you would follow to develop a more
reliable measure of commitment
C12 (a) Define the concept of reliability (of measures) in a clear concise and
accurate manner (b) Provide a formula that expresses the reliability of a measure
in terms of two components of variance ie total variance and the error
variance
D) Multi-level Assessment
D1 One of the major challenges for group-level research is the issue of aggregation of
individual data to the group level
(a) Under what conditions (eg types of data number of raters) should the various
interrater agreement and reliability methods be used (Rwg Kappa and Weighted
Kappa percent agreement average pairwise correlation ANOVA methods
(interclass correlation coefficient WABA)) What are the advantages and
disadvantages of each of the methods
(b) Explain the controversy between Frank Schmidt Larry James and others
regarding the differences between interrater agreement and interrater reliability
Who is right Do the differences matter in research practice
Defend your answers
(c) Review two articles from the organizational behavior literature that have had to
deal with aggregation issues Critique the methods the authors used to make
aggregation decisions
(d) Provide some advice to researchers regarding what they should do if interrater
agreement and reliability indices indicate that it is not legitimate to aggregate their
data
(e) Provide some ideas for avoiding the need to aggregate in group-level research
through creative research methods and measurement strategies
D2 Cross-levelmulti-level research is becoming more evident in the organizational
research literature This type of research raises many issues and presents many
challenges in terms of designing the research measuring variables and collecting
and analyzing the data Assume that you are interested in aggregating data (eg
from the individual to the group or from the firm to the industry) for one or more
variables What are the major issues you will need to deal with
D3 A researcher wants to measure organizational climate for continuous learning
Organizational climate is operationalized as a shared consensual aspect of the
organization -- the shared perception among employees that the organization values
and supports continuous learning Describe how you would measure organizational
climate in this case Specify (a) the level (ie individual group organization) at
which the construct exists (b) the level at which you would measure the construct
and (c) the procedures that you would use to establish that measurement is aligned
with theory (ie the construct validity of the measure)
E) General (Measurement)
E1 Studies in organizational behavior research often rely on single-item measures of
key constructs The use of single-item measures has long been criticized based
on the premise that single-item measures are unreliable However Wanous
(Wanous amp Hudy 2001 Wanous amp Reichers 1996 Wanous Reichers amp Hudy
1997) has recently argued that single-item measures can exhibit adequate
reliability Wanous based this conclusion on a procedure for estimating the
reliability of single-item measures using the classic formula for correction for
attenuation Subsequent studies have yielded mixed results regarding the
conclusions of Wanous (eg Loo amp Kells 1998 Nagy 2002) and the veracity
of the perspective advocated by Wanous remains in question Summarize and
assess the arguments for and against the use of single-item measures and
evaluate the procedure and evidence offered by Wanous regarding the reliability
of single-item measures Based on your assessment and evaluation develop
recommendations regarding the use of single-item measures in organizational
behavior research

E2 Ipsative measures have become prevalent in organizational behavior research
Ipsative measures ask respondents to answer questions relative to one another
such that the scores for all questions sum to the same constant for all respondents
Examples of ipsative measures include rankings Q-sorts and the allocation of a
fixed number of points (eg 100) across a set of response options Ipsative
measures may be contrasted with absolute measures which ask respondents to
answer questions independently from one another Absolute measures are
exemplified by rating scales using an interval or ratio numeric response format
The relative merits of ipsative and absolute measures have been debated for
decades (eg Cornwell amp Dunlap 1994 Hicks 1970 Johnson Wood amp
Blinkhorn 1988 Saville amp Wilson 1991 1992) yet the fundamental issues
underlying this debate have not been adequately addressed in organizational
behavior research For example measures of organizational culture and values
are often ipsative and some researchers advocate these measures over absolute
measures (eg Meglino amp Ravlin 1987 OReilly Chatman amp Caldwell 1991
Ravlin amp Meglino 1987 see also Rokeach amp Ball-Rokeach 1989) Review the
relative merits of absolute and ipsative measures Based on your review which
form of measurement is most appropriate and why Do your conclusions depend
on the construct being measured If so what types of constructs are best suited to
ipsative measures and what types are best suited to absolute measures Next
apply your conclusions to the measurement of culture and values in
organizations What specific arguments have been advanced in favor of ipsative
measures of culture and values How sound are these arguments Should ipsative
measures be used in the study of organizational culture and values If not how
can absolute measures of culture and values be developed that address the
concerns voiced by advocates of ipsative measures Provide a specific example
of the type of measure you would propose

facets of a concept Although such measures are prevalent and in some cases are
advocated (eg Law et al 1998 1999) they can present a variety of conceptual
and methodological problems Describe the specific problems associated with
measures that use items representing different facets of a concept Compare these
problems with the purported advantages of such measures Conclude by
indicating whether and under what conditions such measures are useful for
organizational research

E5 Suppose Roberta Von Eisenbrick is a researcher interested in the consequences of
AFFECTIVE CONFLICT (AC) in decision-making teams She gets access to a
variety of outcomes assessment committees at each of 87 different schools in
the Dallas Independent School District and gains permission to tape-record two
of their meetings (one in February and one in March) Such committees have
been formed to develop quantitative ways to track pursuit of school goals and
provide accountability to local and state governments These are often divisive
teams with heated meetings because what gets assessed is what usually gets
rewarded After both of these meetings the committee members each
fill out a short questionnaire that contains 20 Likert-type items measuring how
much AC occurred (eg People in our group often get angry with each other)
The individual scores are summed across items then averaged across team
members to come up with a group-level AC score for each of the 87 2
meetings The same procedures are followed for a 5-item measure of Group
Cohesiveness (GC) which is predicted to be reduced by higher levels of AC
Roberta also listens to every tape and from her expert judgment she rates each
groups meetings on the same 20 items Those 20 ratings are summed for each of
the 87 2 meetings Now Roberta is interested in evaluating her measure She
wants it to have excellent psychometric properties including reliability and
construct validity

least three kinds of estimates and the sources of error each one assumes or is
estimating Pick one of those kinds of estimates and provide a rationale for using
it
c What is construct validity Discuss how the (un)reliability of the AC measure
could affect the conclusions one would draw from a study involving it and GC In

validity and the connection between reliability and the probability of Type I or
Type II statistical errors

are the essential elements of these critiques What are some remedies to the
problems engendered by significance testing and why have these remedies not
been widely adopted

D) ModeratorsMediators
D1 Moderation and mediation provide different ways to model third variable effects
(a) Please define both of these terms (b) Sketch a conceptual model to show how
each relates to main effects (c) Using variables of your choice please write
hypotheses to reflect both (d) Explain how each is tested analytically
D2 Discuss moderators and mediators Provide an example of how (1) a moderating
variable influences the relationship between the independent and dependent
variable and how (2) a mediating variable influences the relationship between
the independent and dependent variable Describe how you would test for both
moderation and mediation using regression
D3 Many theories in organizational research predict that the effects of one variable
on another are moderated by a third variable Such moderator effects are
typically tested by entering the product of two variables as a predictor after
controlling for the two variables that constitute the product Several researchers
have pointed out that this product is often highly correlated with the squares of
the two constituent variables and have suggested that moderating effects may be
tested after controlling not only for the two constituent variables but also their
squares (eg Cortina 1993 Ganzach 1998 Lubinski amp Humphreys 1990
MacCallum amp Mar 1995) Discuss the strengths and weaknesses of this
approach as compared to methods that use only the product term and its
constituent variables Conclude with recommendations as to when and under
what conditions organizational researchers should test moderator effects with the
squares of the constituent variables in the equation

D4 Assume you are interested in studying relationships amongst three variables X
Y and Z Your first hypothesis posits Z as a mediator of the relationship between
X and Y Your second hypothesis posits Z as a moderator of the relationship
between X and Y Draw the figures depicting each of these hypothesized
relationships and describe (make sure to write regression equations) how you
would test each of these hypotheses
D5 The amount of time and effort that the average person pours into his or her job
has risen steadily over the last two decades such that the average person now is
working one more week per year than the average person in the mid 1970s This
steady increase has fueled research interest in the construct of Job Burnout (JB)
which is an emotional and physical exhaustion associated with ones work
Organizational Stress (OS) the perception of greater demands than available
resources in ones work environment is thought to be one of the chief
antecedents of JB However time spent under OS is thought to make its affects
on JB accumulate or worsen Work Role Withdrawal (WRW) the avoidance of
responsibilities or the deliberate reduction of inputs to ones job is believed to be
the chief consequence of JB
a Formally state these ideas as verbal hypotheses as equations and as a complex
directed graph (circle amp arrow diagram)
b Conceptually what is a mediator Define the term and identify the mediator in
your hypotheses in (a) What elements or steps in a study design (not statistics)
that would be helpful for detecting the mediating relationship that was proposed

subdomains of management Further demonstrate your understanding of
moderator variables by picking which variable in (a) is the moderator Show the
moderating relationship in an X-Y (or multi-layered) chart Again what elements
or steps in a study design (not statistics) would be helpful for detecting the
moderating effect implied above

recommendations You conduct a well-designed controlled study (details are unimportant) and discover students who use the new book perform 10 better on a standardized subject
matter exam than those using the old book (p = 027) Both books are readily availabe their prices are almost identical and both are equally acceptable to the instructors What is your recommendation to the chair
F1 Attached is the beginning of an article Your task is to write the results section by
1 making up and reporting plausible descriptive statistics that will help the
reader understand the results of the statistical tests you report and the nature of your
sample (Hint this can be presented in the form of a table)
2 describing and defending your choice of appropriate statistical tests of the
hypotheses and the steps that you would go through in carrying out these tests
3 making up and reporting results of these tests that are consistent with your
descriptive statistics and with any information in the rest of the article about the
results found (Hint this can be presented in the form of a table)
4 describing how well these results provide support for the hypotheses You
may want to note any relevant threats to validity here
Be sure to state any assumptions you make
F2 Assume that the Personnel Manager of a local firm Ms B dFlandres hired you to
analyze some data that her assistants had collected over the past several years The
data consist of (a) job performance ratings that were made in June of 1990 and (b)
scores on 25 predictor variables (eg measures of education job experience job
tenure job aptitude personality) that were measured when the individuals were hired
(between April 1987 and May 1988) She had data from only the 110 subjects (60
males and 50 females) who were hired during the period and were still employed by
the firm One objective of your analysis (analyses) is to determine how well the
performance criterion can be predicted by the predictors What strategy would you
use in analyzing the data Describeexplain (b) Is sample size an issue for your
analyses Explain If it is what will you do to deal with problems stemming from
sample size Assume that no additional data can be collected at this time (c) Some
preliminary analyses that you do reveal that five of the predictor variables correlate
(zero-order basis) about 75 with one another Will this influence the analyses that
you use Will it influence the validity of conclusions derived from your proposed
analyses (d) Ms dFlandres is interested in knowing if the predictor variables are
equally effective in predicting the job success of males and females What analysis
or analyses would you do to deal with this issue
F3 Assume that you have been provided with data on 12 conceptually distinct variables
that are moderately correlated with one another at the empirical level The data are
from students in four different college majors ie astronomy (A) biology (B)
criminology (C) and demography (D) The 12 measured variables fall into the
general categories of mental health (tension emotional withdrawal hallucinations
guilt feelings blunted affect and suspiciousness) and job satisfaction (work itself
supervision co-workers pay promotion prospects and working conditions) Your
task is to determine if the individuals in the four college majors differ from one
another on the 12 measured variables
(a) What statistical technique(s) would you use to test for group differences
Explain Be specific about the procedures(s) that you would use
(b) What statistical estimate would you use to estimate the extent to which the
groups differ from one another Be specific
F4 The following statistical table published in a recent issue of Work amp Occupations
was taken from an article discussing variables influencing resistance and citizenship
behaviors in the workplace Resistance behaviors include playing dumb withholding
effort work avoidance subverting particular managers and sabotage Citizenship
behaviors include cooperation engaging in peer training use of insider knowledge to
facilitate production commitment to organizational goals giving extra effort freely
Both measures are global constructs aggregated to the interval level and
standardized
The table reports the results of a series of ordinary least squares regression equations
with standardized coefficients Explain the meaning of the statistics presented What
do these statistics tell us generally about the relationship between resistance
behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows
Anomie Index -standardized interval level measure tapping multiple dimensions
The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)
F5 Researchers collected data from a sample of 350 companies on the following
variables
size (measured as number of employees)
Business Strategy (a nominal variable with 2 response options low-cost provider or
differentiator)
HR Strategy (a nominal variable with 2 response categories High commitment or
low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

assumptions usage and limitations
O3 How do exploratory and confirmatory factor analysis differ What are the
advantages and disadvantages of each
O4 Describe the differences between exploratory factor analysis (EFA) and
confirmatory factor analysis (CFA) When would you use one verses another
Are there ways to use EFA in a confirmatory way Can you use CFA in an
exploratory way Also describe the difference in principal components analysis
(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression

c the type of quantitative output that results from applying the technique
d how a researcher would use the output in his or her research
e how confirmatory factor analysis is different from exploratory
f the important issues and problems in using the technique
P) Structural Equation Models
P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)
Please comment on these restrictions versus access argument Which side do you
take
What are the strengths of SEM Give some examples
What are the weaknesses of SEM Give some examples

design you come up with has a specific name use it As part of describing your
design discuss how the data would be analyzed and what particular effect you
would look for
G7 Why are experimental research designs held in such high regard
G8 Compare and contrast experimental quasi-experimental and correlational research
designs What characteristics separate these three designs What are their
advantages and disadvantages especially in comparison to one another
G9 What is the difference between a within-subjects experimental design and a
between-subjects experimental design When might a within-subjects design be
appropriate When might it be inappropriate
G10 Describe the difference between a basic within subjects and between subjects
experimental design What are the advantages and disadvantages of each
especially in comparison to one another Give an example from your area of
research in which each would be appropriate
G11 What are the major threats to the internal validity of a pretest - post test
nonequivalent control group design How can this design be improved with regard
to increasing a researchers ability to make causal inferences
G12 A production manager is interested in testing the hypotheses that participation in
quality circle programs will result in increased productivity and reduced
absenteeism A questionnaire is administered to a group of 92 employees
concerning their attitudes toward such programs and 46 with the most favorable
attitudes who are willing to participate are selected for the treatment group The
remaining 46 are the control group Measures of performance (unitsmonth for the
group) and absenteeism (lost daysmonth for the group) are kept over a three month
period during which the treatment group has weekly quality circle meetings The
results are as follows
Month 1 Month 2 Month 3 Month 1 Month 2 Month 3
Performance Absenteeism
Treatment 100 115 121 6 9 4
Control 110 108 113 6 8 5
The manager calculates t tests between month 1 and 3 The only significant
difference is performance for the treatment group so the manager concludes that
quality circles raise productivity but do not have an effect on absenteeism What
are the primary threats to internal and external validity in this study What are
possible alternative explanations for the differences (or lack of differences)
between the two groups What additional information might help explain these
results
G13 One stream of current strategy research contains event studies In these studies
investigators basically correlate the reaction of a financial market to the presence
andor absence of the occurrence of some event at a firm (eg the resignation of a
CEO) In a different approach to such a study suppose that one investigator (Jean)
conducts a natural field experiment on the effects of competitor mergers on a
firms environmental scanning activity Through previous arrangement Jean has
been working with 5 medium-sized computer hardware and 5 medium- sized
software firms on the west coast Shes been collecting a paper trail of internal
memos reports and phone calls that might measure environmental scanning
activity Shes been finding that the firms in both industries do about the same
amount of scanning (no significant differences) However in the midst of her data
collection Norton announces a merger with Symantec (software) A year later
Jean compares the amount of post-merger environmental scanning in the software
industry with that in hardware industry Just as Jean had hypothesized a t-test
shows a greater amount of post-merger scanning among the software firms She
concludes that her hypothesis was supported mergers of competitors cause an
increase in scanning
Critique the study described above in terms of its design flaws Identify the design
Jean used Briefly allude to problems the study has with external validity but
concentrate on the Cook and Campbell threats to internal validity Provide a
rationale for why each threat is or isnt operating in the study Link each of the
relevant threats to the specific constructs being studied (mergers and environmental
scanning) Finally do a summary evaluation -- what can be learned from this
study
H) Quasi-Experimental Design
H1 The University of Mississippi observed that the graduation rate of students with poor
grades during their freshman year was much lower than those with better grades
Wanting to improve the chances of these low performing students they tested the
effects of a new rule for freshmen The rule stated the following At the end of their
first semester all students with a GPA between 200 and 225 must register for
EDUC 1003 during their second semester Students with a GPA lower than 200
were put on academic probation EDUC 1003 consisted of a course whose objective
was to help students develop good study skills The theory was that poor study skills
were a significant cause of poor academic performance and that study skills could
be learned
They wanted to evaluate the effectiveness of this intervention so they collected data
on the GPAs of students beginning with their first semester and continuing through
to their third semester At that point they wanted to analyze the data to determine
whether the new rule was making a significant difference in the students academic
performance
What is the best way to analyze these data to reach an interpretable conclusion
Describe your approach and then discuss the major threats to validity that it has
Their sample size of students was as follows
Total N= 3454 (these are students who completed all 3 semesters)
Number of students with first semester grades between 200 and 225 (and thus took
EDUC 1003) was 956
H2 A nationwide furniture company wants to determine if a diversity training
program will improve individual sales performance on the floors of its urban retail
outlets A group of 45 salespeople in one city were given two weeks of training
Measures of individual sales performance were taken once two months prior to the
program and once two months after Forty-five salespeople (who did not receive the
training) in a similar city had the same measures taken at approximately the same
points in time The training group increased their average weekly sales from $14000
to $16500 while the non-training group improved theirs from $13000 to $14500
The change for the training group is statistically significant the change for the non-
training group is not
How would the interpretation of these results in this quasi-experimental design
differ from a true experimental design What are the threats to internal validity in
the above study and how might they be operating (be specific) What additional
information and analyses would be useful in controlling for these threats
H3 An accounting firm is interested in determining if a re-training program will reduce
errors made by its audit teams A group of 45 auditors in the home office location
are given two weeks of re-training Measures of the frequency of detectable errors
are taken once two months prior to the program and once two months after Forty-
five auditors in similar office at a branch location have similar measures taken at
approximately the same points in time The training group reduced their average
number of errors per audit from 8 to 3 while the non-training group reduced theirs
from 11 to 9 The change for the training group is statistically significant the change
for the non-training group is not
How would the interpretation of these results in this quasi-experimental design
differ from a true experimental design What are the threats to internal validity in
the above study and how might they be operating (be specific) What additional
information and analyses would be useful in controlling for these threats
H4 Describe the main classes of threats to validity that are found in quasi-experimental
research designs
H5 Dr Delta an organizational development consultant was hired by a firm that has
600 pizza parlors nationwide to assist in implementing organizational changes that
he hopes will result in higher levels of job involvement At the outset of the study
subjects had jobs with very low levels of enrichment and were paid on an hourly
basis He designed an experiment in which stores were randomly assigned to one of
three treatment conditions Condition 1 subjects experienced job enrichment (JE)
and a change to performance-based pay (PBP) Condition 2 subjects experienced
only JE and Condition 3 subjects experienced only PBP The parlors were
sufficiently far apart from one another and communication among the parlors so
poor that subjects in any parlor were totally unaware of changes made in other
parlors At the end of 18 months he measured the job involvement levels of workers
and then tested for differences between the three conditions using a standard one-
way analysis of variance In view of Dr Deltas design answer the following
questions
How sound is Dr Deltas design Comment on the weaknesses of the design
I) Interrupted Time Series Design
I1 What threats to internal validity are and are not ruled out by an interrupted time series
design that includes the introduction of a treatment and its removal at a subsequent
time period List and explain In the process be certain that you provide a diagram
that illustrates such a design
J) Validity Some Questions are about the validity of a measure others about experimental validity)
10) Identify four threats to internal validity and briefly describe what they mean
J1 It was some time ago that the tripartite view of validity was abandoned in favor of a
unitarian view in which different evidentiary bases for validity might be put forward
Binning amp Barrett (1989) represent an attempt to place multiple evidentiary bases into a
single framework Cook amp Campbell (1979) describe four aspects of validity but they
arent really meant to represent evidentiary bases Adding to the confusion is the fact
that while Binning amp Barrett and Cook amp Campbell use some of the same terms these
two pairs of authors clearly mean different things by these terms and intend for them to
be used in different ways Your task is to 1) Describe the evidentiary bases discussed
by Binning amp Barrett 2) Describe the aspects of validity described by Cook amp
Campbell 3) Describe the similarities and differences between the two lists including
the different purposes served by the two lists and 4) Present a single framework that
incorporates both This last task is the most important of the four
J2 What are the types of validity How would each affect an empirical study IC
J3 Define both internal and external validity Which is more important (it is not okay to
say that they are equally important) Defend your reasoning
J4 Why might someone argue that the construct validity of a measure can never really be
established
J5 Describe each of the following forms of validity content convergent discriminant
criterion-related and construct How is each assessed How do they related to each
other Which is most important (Make sure you defend your answer)
J6 Define and explain 6 of the 8 types of validity listed below and describe the type(s) of
information each provides Choose one specific type of study as an example (eg
cross-sectional study experiment quasi-experiment simulation ethnography etc) and
compare and contrast the usefulness and importance of each type of validity for that
type of study
-- Concurrent validity
-- Construct validity
-- Content validity
-- Convergent validity
-- Discriminant validity
-- Statistical conclusion validity
-- Internal validity
-- External validity
J7 Designing empirical research has been called making a series of trade-offs
Unfortunately decisions that are made to increase one desired quality (like internal
validity) can also decrease another desired quality (like external validity) For each of
the issues below discuss the concerns involved (ie the trade-off) and identify the
qualities that are being increased or decreased
a laboratory vs field study
b using a 5-item measure vs a 1-item measure
c using a student sample vs a sample of full-time employees
d using a sample of employees from one company of 5000 vs 500 employees from
each of 10 companies
e collecting your data using one method vs collecting your data using multiple
methods
J8 There are four major types of validity in social science internal validity external
validity construct validity and statistical conclusion validity Please address the
following three issues concerning validity
a What is the meaning of the four major forms of validity (ie internal and external
validity construct validity statistical conclusion validity)
b Are there trade-offs that can or must be made among the four types of validity
d Describe how the concept of validity varies across the research traditions of
experimental vs observational research
IC
J9 The quality of research is often assessed by examining validity issues As you are
aware there are numerous typesforms of validity (eg internal and external validity
construct validity statistical conclusion validity) These types of validity address
different aspects of the research process For this question please address the following
issues
a What is the meaning of the four major forms of validity (ie internal and external
validity construct validity statistical conclusion validity)
b Should there be a priority among these forms of validity If yes why If no why not
c Does the concept of validity vary across research traditions (ie experimental vs
observational research) If yes why If no why not
J10 External validity has received considerable attention in the social and behavioral
sciences Some researchers argue we are too concerned with the external validity of our
findings while other researchers argue that we are too unconcerned with external
validity Several points of view have been developed to explain what is external
validity When answering this question please be sure to address at least the following
issues
a Compare and contrast alternative conceptualizations of external validity
b Some researchers have argued that the role of external validity is invariant across
research traditions (ie experimental vs observational research) Defend the
perspective that the role external validity is invariant across these two research
traditions In addition present the weaknesses of this perspective
J11 In designing a research study researchers must consider trade-offs between internal and
external validity Explain what is meant by internal validity and external validity What
is the nature of these trade-offs How would you evaluatedetermine which is more
important internal or external validity for a particular study Why is this such an
important issue in organizational studies
J12 A researcher conducted a quasi-experiment to test the effects of participative decision
making (PDM) on job attitudes of employees Employees from different departments in
a large organization were assigned to either a treatment group (PDM implemented) or a
control group (no PDM) Random assignment was not possible because of work
schedules coordination of tasks etc Thus the design can be considered an untreated
control group design with pretest and posttest and is represented as follows (where
O=observation X = treatment)
________________
O1 X O2
-------------------------
O1 O2
_________________
The results of the experiment are presented in the graph below [no graph provided]
The dependent variable is job satisfaction and is measured on a 100 point scale (with
100 being extremely satisfied) How amenable are these results to causal interpretation
What is (are) the major threat(s) to internal validity B if any B for this type of design
given these results What steps can be taken to assess the extent of this (these)
threat(s)
K) Data Collection Methods
14) Describe the various methods of data collection (eg survey interview observation etc)
available to a social scientist What are the advantages and disadvantages of each relative to
each other
K1 Within micro organizational research much criticism has been raised concerning
the reliance on self-report survey data What potential problems does self-report
survey research raise How big of a problem do you think this is
K2 There are a number of methods for collecting data (eg survey interview archival
etc) that are available to a social scientistorganizational researcher Discuss each in
terms of their strengths and weaknesses both on their own and in comparison to one
another
K3 Pick an important construct in your favorite area of management research for which
there is some controversy about how it should be measured or operationalized (eg
environmental munificence or growth need strength) Give the prevailing verbal
definition of the construct and analyze the measurement controversy from two
broad angles First discuss how the controversy may or may not stem from claims
about how one measure is better or worse than another because it (or the other) is an
(a) archival record (b) direct observation (c) social report or (d) self-report That is
what are the relative strengths and weaknesses of each of these types of
measurement for the construct youre discussing Second discuss the construct
validity of the most commonly used measure(s) of this construct To answer this
second part you need to discuss just what construct validity is and how it can or
cannot be demonstrated In the situation you describe what could be done to
demonstrate or improve the construct validity of existing measures
K4 Interviewing in some form has been the workhorse for data collection in a variety
of research traditions positivistquantitative ethnographic feministpost-modernist
and increasingly historical research While each tradition elicits information from
respondents the goals and processes involved in interviewing vary considerably
across research traditions Discuss the purposes of the interview the relationship
between data and theory the roles assumed by the interviewer and the respondent
and the relevant criteria for assessing the validity and reliability of the information
obtained In addition compare and contrast the use of the interview as a data
collection method in the positivistquantitative tradition with its use in one of the
alternative traditions
L) Common Method Variance
L1 Many of us have had concerns about the reviews of our survey research which
suggest that data analyses of surveys are biased because of common method
variance effects of individual differences such as negative mood negative
affectivity and social desirability and the reliability and validity of the constructs
we are attempting to measure Define how these problems affect a research issue in
organizational behavior and the steps that might be taken to minimize such potential
criticisms of papers based on analyses of self-reported data through survey
instruments
L2 In a series of papers by Spector (1994) Schmitt (1994) and Howard (1994)
published in the Journal of Organizational Behavior arguments were provided for
and against the use of self-report questionnaire measures One of the issues
discussed that could limit conclusions drawn from relationships observed using self-
report measures was method variance What is meant by method variance what are
its sources and what impact is it expected to have on research findings
M) Sampling
M1 The manufacturing census samples all plants of 250 employees or more For
plants of 5-249 employees it takes a size proportional sample Plants of 1-4
employees are not sampled What challenges does this sampling method provide
to researchers What could you do to account for these problems if you were
TH
studying organizational (not plant) growth
M2 New York State has approximately 250000 employees in over 70 state agencies
commissions and boards ranging in size from approximately 50 to over 5000
employees Assume that you wanted to draw a representative sample of 1000
employees Describe two ways that you could draw such a sample and briefly
describe the advantages and disadvantages of each of these sampling approaches
IC
M3 The director of a national non-profit agency with approximately 10000
employees located primarily in regional offices in each of the 50 states the
United States has approached you and asked you to develop a study
(organizational survey) of organizational culture within the agency The agency
is about to embark on a variety of change initiatives including developing team
structures and the study is meant to examine various elements of organizational
culture that are potential barriers to change The director has indicated that he
would like to have the data analyzed at both the individual and office level of
analysis Because of funding limitations the agency will only be able to send the
survey to 1000 employees The director has indicated that there are three ways
of sorting employees all employees listed alphabetically all employees listed
alphabetically by state and all employees listed alphabetically by region (there
are between five and ten regions per state) Given these three ways of sorting
employees describe at least three different sampling approaches and the
advantages and disadvantages of each
M4 In your role as Teacher of Organizational Studies you are asked to prepare a
tutorial for beginning doctoral students on sampling design Assume that this
tutorial is part of a basic class in research design and that students in this class
have had a basic statistics course up to and including multiple regression Your
tutorial should focus on briefly defining and explaining the differences between
probability and non-probability samples You should make sure to present and
describe several types of probability samples (eg random systematic
stratified etc) and non-probability samples (eg convenience snow-ball quota
etc) and discuss general principles for when to use a probability vs a non-
probability sampling design For each sampling design you should also provide
at least one clear example of a situation where this type of sampling design is
appropriate
N) Cross-Cultural Research
N1 Discuss the problems in conducting cross-culturalnational comparison in terms
of (1) conceptualization and (2) research design and data collection
Define the three levels of measurement invariance How would the problems that
you have identified in part (a) affect measurement invariance How would you
examine measurement invariance by confirmatory factor analysis
TH
N2 Explain why using national boundaries as independent variable in cross-cultural
studies may not be appropriate in terms of theory and research methods What
alternative ways would you recommend
IC
O) General
O1 In your readings research has been described as choices among conflicting goals
(desiderata) For instance when choosing among research strategies a researcher
must choose among the desiderata of precision realism and generalizability The
trade-offs among desiderata occur for all aspects of research that is for the selection
of theories the treatment of independent variables research strategies the selection
of the problem to study rules of evidence for determining the meaningfulness of a
research finding and even the frameworks that describe the research process
Discuss what you see as the major trade-offs for each of the following aspects of
research That is discuss what you see as the major strengths and weaknesses
(advantages and disadvantages) of each aspect
a The trade-offs between internal and external validity
b The manipulation of the independent variable vs the observation of the
independent variable
c Basic vs applied research
3 DESIGNING A RESEARCH STUDY
A) General (Research Design)
3) Why is control so important in research design What are the different ways it can be
achieved (give a brief description of each control method) What are advantages and
disadvantages of each
A1 It has become almost a truism to note that the choice of methods influences theory
and questions data and conclusions (the causal direction might also be reversed)
Briefly discuss how the methods used have influenced research in any two of the
following areas leadership power and politics organization culture organization
justice Compare and contrast as possible Suggest some potentially fruitful
methodological directions for future work in these same topical areas and dont be
shy about reflecting on broader issues of how the field of organizational behavior
constructs its realities Lastly tie your discussion and reflections back to your own
future as a researcher what lessons or guidance do you derive from your
understanding of these issues
A2 Characterize as fully as possible what you see to be the methodological approach or
approaches in strategic management research Is there a dominant method or a wide
variety Discuss the reasons for the situation What are the advantages benefits etc
of the approach(es) in use What assumptions (ontological epistemological
ideological) do they embody Are current efforts ideal or at least adequate Are
there other approaches that could be useful If so how might researchers be
encouraged to use these as well If you see no advantage to more variety in
methodological approach support that point of view
A3 Describe a research question or area of interest to you and why you think it is not
only of interest but significance Using your understanding of research methodology
describe two ways of pursing the question that are as divergent on as many
dimensions as you can imagine Describe the advantages and disadvantages of each
approach How strong a link or fit is there between a research question and a
method
A4 In his 1957 article entitled The two disciplines of scientific psychology Cronbach
discussed the assumptions goals and methods used in experimental methods and
correlational methods in psychology
a According to Cronbach what is the main difference between the two disciplines
b Discuss the strength and weaknesses of each discipline
c What if anything could be done to improve the situation
B) Designing a Research Study
B1 Cook and Campbell describe the experiment as the research design with the
greatest methodological rigor However given the constraints present in most
organizations I-O Psychologists cannot often conduct experiments in applied
settings and must settle for techniques with less control than experiments
Describe a study to investigate the relationship between participation in a
supervisor training program and work performance which could realistically be
conducted in an organization If an experiment is not possible describe how you
would go about maximizing your ability to draw valid conclusions from your
design
B2 The XYZ Co has recently developed a sexual harassment web-based training
program The developers claim the program will cut training time and costs and
will be as effective or more effective than classroom-based sessions They
believe that this will be due to the increased availability of the program and the
ability for participants to review program material on demand Before the XYZ
Co developers launch this product they want you to determine if their claims
have merit Explain how you would design a study for this purpose
B3 Research suggests that demographic diversity improves group creativity but
reduces group efficiency Some argue that demographic diversity is just a proxy
for value and experience diversity and that demographic diversity on its own is
meaningless Design a test to settle this argument
TH
B4 E-mail has become a common form of communication in organizations and is
used for both formal and informal communication Because it has become so
IC
popular some people complain that the frequent use of e-mail leads to
miscommunication because they receive communications in e-mail that should
be accomplished through face-to-face or telephone conversations where there is
an opportunity for interaction You are interested in looking at this
phenomenon You are most interested in describing how e-mail is used for both
formal and informal communication and in examining the effect of the e-mail
use on organizational communication effectiveness Design empirical research
to address those issues
Describe your study in detail thoroughly explaining the research design
sampling plan data collection procedures ethical issues and proposed data
analysis for your research design Be sure to discuss the internal and external
validity of your research Which validity threats are ruled out and which
remain
REMEMBER Be thorough Your research design should demonstrate that you
are a competent researcher who is knowledgeable about the proposed research
methodology or methodologies Therefore be sure that you carefully describe
and give technical explanations for each component of your research
B5 Choose a specific situation involving employee selection eg artists for an
advertising agency (a) What strategy would you use in selecting the selection
measures (b) How would you combine the measures eg which measures
would you combine in a compensatory manner and which is a noncompensatory
manner (c) How would you assume test fairness defining various measures of
the term (d) How would you make final selections (e) How would you
validate your procedure (f) What considerations would enter in if your
company were too small to provide validation data (g) What difference would
it make if you were developing a procedure for deciding whether trainees
should be promoted as opposed to making new hires Please note--emphasize
but do not limit yourself to statistical issues
B6 There is evidence in the marketing literature of a non-monotonic relationship
between the expectations that customers have for retail service and their
eventual level of satisfaction with that service That is as a customers
expectations for service increase so does their eventual service satisfaction --
up to a point After that point the greater the expectations the lower the
eventual satisfaction Develop a hypothesis that includes a moderator variable
that might account for this evidence Give some reasonable rationale for it State
your hypothesis verbally as an equation as a directed graph (circle amp arrow
diagram) and as an X-Y function chart Discuss how it would or would not be
possible or useful to test your hypothesis via a laboratory experiment In your
discussion cover how and why a researcher could (not) manipulate the
independent constructs involved (mode X) whether or not random assignment
to conditions (mode R) is possible (including how may conditions would be
necessary) which alternative constructs could or could not be controlled (mode
K) and which constructs should be measured (mode Y)
B7 Assume you are the chairperson of a committee that must evaluate
undergraduate programs at your university Your task as chairperson is to
devise an approach (a design a research strategy a set of measures) that will
allow you to evaluate undergraduate programs Make sure that your approach
can be used in the future and at other comparable universities When developing
your plan be sure to address at least the following issues
a the type of design you would select Compare and contrast the selected design
with another possible design
b the type of research strategy you would select Compare and contrast with
another possible strategies
c discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
B8 Assume you are an organizational research design expert assigned to the
Strategic Planning Department of a large multi-national manufacturing firm
The Department has developed a new PC-based software package called
STRATPACK The software (and a one-week training course to learn how to
use it) is intended to improve the long-range planning ability of middle and
upper-level managers
Your job as research design expert is to devise research (a design a research
strategy a set of measures) that will allow you to evaluate the effectiveness of
the STRATPACK program Describe a research design for evaluating the
program Make sure that your research approach can be used in the future and at
all sites in the company When developing your plan be sure to address at least
the following issues
a discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
b the type of design you would select (eg a design where you manipulate the
independent variable versus observe the independent variable) Compare and
contrast the selected design with another possible design
c how your design deals with the major forms of validity Be sure to examine at
least internal external and construct validity
B9 Assume you are a consultant hired to evaluate the effectiveness of an industrial
safety program undertaken by a large manufacturing organization The safety
program is a behavioral one that provides rewards such as monetary bonuses or
extra paid vacation days for safety behaviors in terms of accident-free days
weeks etc Your task is to devise an approach (a research strategy a design a
set of measures and a general analysis strategy) that will allow you to evaluate
the safety program Because of the potential for the influence of many
extraneous variables on any safety program it is difficult to design research a
single cross-sectional study than can evaluate the impact of a single safety
program How would you design a study to evaluate the impact of the safety
program When developing your plan be sure to address at least the following
issues
a the type of research strategy you would select Compare and contrast with
another possible strategies
b the type of design you would select Compare and contrast the selected design
with another possible design
c discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
B10 One of the most important areas of research is forecasting of human resources
needs based on strategic positions of organizations For example NY State must
carefully forecast its human resources needs as it proceeds with significant lay-
offs of state employees Future human resources needs are generally evaluated
by either statistical ie regression or simulation or clinical judgment i e
supervisors judgments methods
a Design a single study that addresses the empirical question of whether
statistical or judgmental methods are better for forecasting human resources
needs You may discuss a program of research but please be quite specific in
your description of the first study
b What are the critical methodological issues in doing this kind of research
c What are the critical applied (or practical) issues in doing this research
d Are the issues in b and c related
B11 In the past decade computinginformation technology has changed many
aspects of organizational life For example the technology can make increased
decentralization possible by improving communication between central offices
and field offices Computer networks and word processors can enhance group
empowerment by making it possible for team members to create and edit
written group products quickly even if the individuals are at different locations
Some have argued that computinginformation technology will foster the
paperless productive office nevertheless others argue that the technology only
increases paper and reduces office productivity You are applying to the
National Science Foundation for a grant to conduct research that examines the
impact of computing information technology on organizational decision
processes The NSF application procedure imposes five basic requirements that
your research design must fulfill in order to receive funding Note A very
significant factor affecting NSF grant decisions is a clear demonstration that the
researcher is knowledgeable about the research methodology used Write your
response to each of the following five grant requirements Be sure not only to
respond to the requirement but also to demonstrate your research
competence
1You must design a study that uses two different methods
(interviewobservation survey experiment or quasi-experiment) Describe your
two methods in detail and provide a rationale for the key elements (eg
sampling data collection proposed analysis) of your methods Be sure to
discuss and evaluate the internal and external validity of both methods
2 As part of your research design you must select a conceptual (latent) variable
central to your proposal (use centralization of decision making as your
variable) and describe how you will develop your own measure (You may not
simply use off the shelf instruments)
3 You must describe how you will test for the reliability of the measure
(centralization of decision making) you developed in step 2 The NSF insists
that you describe how you will evaluate both the temporal stability and the
internal consistency of your measure Be sure to discuss what temporal stability
and internal reliability mean and how they are related
4You must describe how you will assess the validity of the measure
(centralization of decision making) you developed in step 2
5 NSF requires a brief statement and defense of the philosophy of science
underlying your research Discuss your position and show how your research
design is consistent with your philosophy
B12 Many organizations in the United States economy have installed some form of
Empowered Teams as an alternative or supplement to traditional bureaucratic
structure Preliminary evidence of the effectiveness of empowered teams
however is mixed--some organizations have claimed success and others have
reported failures The evidence however is predominantly anecdotal--written
for trade magazines by the organizations themselves There are few rigorous
empirical studies assessing the effectiveness of empowered or self-managed
teams You are applying to the United States Department of Labor (USDOL) for
a grant to conduct research that examines the effectiveness of empowered
teams The application procedure of the USDOL imposes three requirements
that your research design must fulfill in order to receive funding Write your
response to each of the three grant requirements The importance of each section
is implied by the evaluation points allocated by the USDOL to each of the three
requirements given in parentheses
1 (50 points) Your study design for assessing Empowered Team effectiveness
must use two different methods (interview observation archival analysis
survey simulation experiment or quasi-experiment) Describe in detail and
thoroughly explain the sampling plan instrumentation data collection
procedures and proposed data analyses for both methods Be sure to discuss the
internal and external validity of both methods and how the two methods
complement one another
2 (30 points) As part of your research design you must select one conceptual
(latent) variable central to your proposal and describe how you will develop
your own operationalization of the measure (You may not simply use off the
shelf instruments) Use the concept of group morale to demonstrate your
operationalization methodology Be sure to explain very explicitly to the
USDOL how you will assess the validity and reliability of the group morale
measure you are developing
3 (20 points) The USDOL traditionally has funded research conducted only
within the general paradigm of logical positivism but now is more open to other
research paradigms as well Your grant proposal must provide a statement and
defense of the explicit philosophy of science underlying your research Describe
your philosophy of science and show how your research design is consistent
with your philosophy
REMEMBER Be thorough You not only must design effective research but
you also must demonstrate to the USDOL that you are a competent researcher
It is absolutely vital to the USDOL that the principal researcher is
knowledgeable about the proposed research methodologies Therefore be sure
that you always carefully describe and give technical explanations for each
component of your research design and explain all technical terms (eg
Cronbach alpha KR-20 Likert scale)
B13 Assume that you are working as part of a research team that is responding to a
RFP (Request for Proposals) from a funding agency for research on work
socialization and newcomer adjustment The RFP calls for rigorous field
research that tests the effectiveness of theory-based interventions aimed at
facilitating the adjustment of new organizational members to complex andor
stressful work conditions The major goal of your teams research is to test the
effectiveness of a self-regulation intervention which trains newcomers to
identify and use relevant social information and cues to regulate work behavior
Your group hypothesizes that self-regulation training will be more effective
than other common treatments or interventions (eg realistic job previews
institutionalized socialization tactics)
You have been included in the team because of your methodological expertise
Your role is to design a rigorous field experiment or quasi-experiment to test he
effectiveness of the self-regulation training program REMEMBER THE
MAJOR CRITERION FOR FUNDING IS THE RIGOR OF THE RESEARCH
DESIGN Design a field study to include in the grant proposal Your proposal
should contain the following two sections
1 Study Design Construct and describe in detail an experimental or quasi-
experimental design to test the effectiveness of your intervention Describe in
detail the experimental groups (including how they will be constructed) the
research setting the sampling plan for study participants the treatment
manipulation and the data collection procedures Also indicate any control or
nuisance variables that may be measured
After describing the procedures write a justification of the design What threats
to validity does it rule out or limit and what threats to validity remain
II Measurement Describe the steps you would take to achieve valid and
reliable measure of the latent (conceptual) variable worker adjustment Your
team feels that as part of the proposal you must develop an original
operationalization of adjustment (thus you cannot simply use existing off the
shelf measures) Indicate in adequate detail how you would operationalize the
measure and indicate how you would demonstrate reliability and validity
B14 In describing their notion of the collective mind Karl E Weick and Karlene H
Roberts note Our focus is at once on individuals and the collective since only
individuals can contribute to a collective mind but a collective mind is distinct
from an individual because it inheres in the pattern of interrelated activities
among many people (p 360) Collective mind is not indexed by within-group
similarity of attitudes ideas or activities A collective mind is one in which
many people or many groups integrate their different attitudes ideas and
activities heedfully As Weick and Roberts note People act heedfully when
they act more or less carefully critically consistently purposefully attentively
studiously vigilantly conscientiously pertinaciously (p 361)
The idea of the collective mind as heedful interrelating is developed in the
following excerpt When people make efforts to interrelate these efforts can
range from heedful to heedless The more heed reflected in a pattern of
interrelations the more developed the collective mind and the greater the
capability to comprehend unexpected events that evolve rapidly in unexpected
ways When we say that a collective mind comprehends unexpected events we
mean that heedful interrelating connects sufficient know-how to meet situational
demands For organizations concerned with reliability those developments
often consist of unexpected non-sequential interaction (p366)
An example of heedful interrelating occurs as a pilot lands herhis aircraft on the
deck of an aircraft carrier The pilot does not actually land She is recovered
A recovery is an interrelated set of activities among air traffic controllers
landing signal officers the control tower navigators deck hands the helmsman
driving the ship etc These activities can be interrelated more or less heedfully
depending on the care with which the different units contribute represent the
situation and subordinate their activities to the single purpose of successful
recovery (p 363)
You are to design a two-part study
Part I You are to design a measurement study which assesses heedful
interrelating (ie collective mind) with a quantitative measure in a replication
of an aircraft carrier flight deck or other situation of your choosing Describe
your research strategies including operationalization of the variable selection of
the sample subjects data collection data analysis and so on for the purpose of
developing a measure of heedful interrelating
Part II Using the measurement tool developed in Part I and any other tools as
needed describe how you would design a study which would compare heedful
interrelating across organizations Choose at least one macro-organizational
variable (eg technology environment) as your basis of comparison Here you
must describe how you would make your selection of organizations to be
compared your data collection procedure data analysis and so on
B15 Many organizations in the United States have installed cross-functional teams to
counteract the silo mentality of traditional bureaucratic structure Preliminary
evidence of the effectiveness of cross-functional teams however is mixed --
some organizations have claimed success and others have reported failures The
evidence moreover is predominantly anecdotal--written for trade magazines by
the organizations themselves Since there have been few rigorous empirical
field studies assessing the effectiveness of cross functional teams the National
Science Foundation has decided to fund research on the topic
Assume that you are submitting a research proposal to NSF for a grant to
research the effectiveness of cross-functional teams Describe in detail and
thoroughly explain the research design sampling plan data collection
procedures ethical issues and proposed data analysis for your research design
Be sure to discuss the internal and external validity of your research Which
validity threats are ruled out and which remain NSF also requires that you
provide a statement and defense of the explicit philosophy of science underlying
your research Describe your philosophy of science and discuss how your
research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but
you must also demonstrate to NSF that you are a competent researcher It is
absolutely vital to NSF that the principal researcher (you) is knowledgeable
about the proposed research methodologies Therefore be sure that you always
carefully describe and give technical explanations for each component of your
research design and explain all technical terms (eg Cronbach alpha KR-20
Likert scale)
B16 Assume that you are submitting a research proposal to the Department of
Commerce (DoC) for a grant to research the effectiveness of virtual work teams
A virtual work team is a leaderless collection of individuals who are
geographically separate from one another and share their expertise using
internet media such as a listserver or Lotus notes The DoC requires that the
researcher use both qualitative and quantitative methods to gather data Describe
in detail and thoroughly explain the research design sampling plan data
collection procedures ethical issues and proposed data analysis for your
research design Be sure to discuss the internal and external validity of your
research Which validity threats are ruled out and which remain The DoC also
requires that you provide a statement and defense of the explicit philosophy of
science underlying your research Describe your philosophy of science and
discuss how your research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but
you must also demonstrate to DoC that you are a competent researcher It is
absolutely vital to DoC that the principal investigator (you) is knowledgeable
about the proposed research methodologies Therefore be sure that you always
carefully describe and give technical explanations for each component of your
research

5 MEASUREMENT
A) Measurement Terms
A1 There are four levels of measurement rigor in management research Discuss each
one What properties do measurements at each level have (ie how much
information do the numbers from each level of measurement convey) How can the
numbers be changed (transformed) and still retain the properties of their
measurement level Pick one construct from a favorite research domain and give an
example of an operationalization of that construct at each of the four levels of
measurement rigor (provide arguments about why you think those examples reflect
each level) Lastly treat each examplelevel as a dependent variable in some
statistical analysis Given an example of a statistical technique appropriate for
analyzing data at that level of measurement rigor
A2 Define (and discuss important features or issues concerning) the following
constructs measurement (Define any six terms)
1 Construct validity 6 Item analysis
2 Likert scaling 7 Semantic differential
3 Cronbachs alpha 8 True score
4 Unobtrusive (trace) measurement 9 Generalizability theory
5 Interval scale 10 Criterion-related validity
11 Sociometric choice measures
B) Operationalization
B1 a) You are conducting a study which requires you to measure Hong Kong real
estate agents self-assessment of performance Since there is no existing
measurement available you have to develop the instrument by yourself
Describe how you would develop the measurement assuming that you have no
idea of how many dimension the construct has
b) Suppose you have developed an instrument consists of 20 questions
measuring 4 dimensions (5 items per dimension) from (a) You collected data
from another 300 real estate agents to validate your instrument Explain how
TH
you would use structural equations model (SEM) to examine the reliability and
validity of the instrument What are other concerns about reliability and validity
that are not addressed by this approach
B2 The research and business world have been fascinated with the concept of
organizational culture However operationalizing this construct has been a
difficult task Discuss the ways in which the construct has been operationalized
(eg technique static v dynamic sample selection generalizability) Critically
analyze each of these methodologies Then choose a methodology you would
use to examine organizational culture and defend your choice Describe how
you would study culture and what more would be known about culture as a
result of your study
B3 Suppose you are setting out to develop a new measure of a construct You want
this measure to be used in survey research and you want to establish its validity
and reliability Your goal is to have at the end of the process a measure that is
defensible and likely to be widely accepted by other researchers studying that
construct What steps would you take to conduct such a program of research
For each step explain the purpose of that step explain why that step is
important explain what methods and statistical procedures you would employ at
each step and explain what evidence you would hope to gather at each step
B4 Assume you are interested in constructing a new measure of (fill in with a
relevant variable from your field) Detail the major concerns that need to be
addressed and the steps that need to be taken in working toward validating this
new measure
B5 Assume that you recently read an article on workplace violence which you
found very interesting The authors argued that one of the predictors of
workplace violence was a construct called propensity to be violent and used a
one-item measure as follows How likely are you to become violent when
provoked You had serious doubts about the authors measure and decided to
develop your own
(a) How would you go about developing items to measure propensity to be
violent
(b) How would you determine whether the instrument was reliable
How would you determine whether the instrument was valid
B6 A concern in organizations is retirement of baby boomers within the next 5 -
10 years This concern is focused on the loss of older employees with skills
critical to the core business functions of organizations In order to continue to
have employees with those critical skills it seems necessary to retrain some
older workers However past practice in most organizations has been not to
retrain older workers for a variety of reasons mostly financial A researcher
working for the Human Resources Department of a large corporation - 13500
employees in 12 different plant locations - hypothesizes that the major reason
for not retraining older workers is ingrained in the culture of the corporation
IC
The researcher feels that older workers are not as highly valued as younger
workers in terms of their potential usefulness after retraining The researcher
searched the literature but found nothing in the existing literature to measure
the cultural value construct What should the researcher do to establish a reliable
and valid self-administered paper and pencil measure of this construct namely
the value of retraining older workers
a Please describe and explain the steps in temporal order that the researcher
must follow to develop a measure
b How would you evaluate the measure based on the technical requirements of
reliable and valid measurement as well as any practical issues in using the
measure considering the size of the employee population
B7 Assume that you are going to conduct empirical research to assess the role that
the complexity of an organizations manufacturing technology plays in
determining the level of centrality of decision making in the organization
Describe and justify the steps you might follow to develop an operationalization
of the concept of technological complexity What standards would you use to
determine if your operationalization is valid
B8 Organizational researchers have several strategies available to them for
gathering information (eg self-report measures archival measures direct
observation and trace measures) Assume that you are going to conduct
empirical research to assess the role that the structure of the organization plays
in determining the level of organizational effectiveness Briefly review the
strengths and weaknesses of the basic strategies (that is self-report measures
archival measures direct observation and trace measures) for measuring
organizational effectiveness Next describe and justify the steps you would
take to develop an operationalization of the concept of organizational
effectiveness What standards and procedures would you use to determine if
your operationalization is valid
B9 One of the most important topics of recent research has been stress in the work
place One of the most important problems with understanding this literature is
the varying definitions and measurement of this construct Suppose you had
decided to investigate the relationship between stress at the work place and dual
career family happiness
a Since there are multiple ways to measure stress in the work place describe
two ways to do this Hint - avoid using two self-report measures
b Describe how you would decide on the best single measure In doing so
describe the steps you would take in evaluating your measure Be sure to define
your meaning of validity and reliability It is important that your measure have
all the necessary psychometric characteristics so that other scientist can trust the
results of your research
c Be certain that you answer the question Validity for what
d In order to understand the results of your study you need to compare your
measure of stress at work with other measures of this construct How would you
do that
B10 Assume that you have been hired by a national survey research company
Shash Inc to write items that will be used in a national survey of attitudes
toward capital punishment There are a number of criteria that can be used to
guide your item writing What are they Briefly describe five (5) such criteria
B11 Assume that you are going to conduct empirical research to determine the
impact of interpersonal trust on organizational decision making Describe and
justify the steps you might follow to develop an operationalization of the
interpersonal trust concept
B12 Assume that you are going to conduct empirical field research to assess the role
that employee empowerment plays in determining the level of organizational
commitment of employees Describe and justifyexplain the steps you would
follow to develop a valid and reliable operationalization of the concept of
employee empowerment
Explain the procedures and standards you would use to determine if your
operationalization is valid and reliable
How would you assess the construct validity of such a measure
Discuss issues concerning the level of observation of your measure and level of
analysis of the data
B13 Assume you are interested in developing a new scale to measure construct X
Further assume that you have used previous literature and your own conceptual
development to delineate 2 dimensions of X specifically XF1 and XF2
Describe the steps you would go through in developing testing and evaluating
this new scale With regard to testing and evaluating be sure to consider the
role of factor analysis (both exploratory and confirmatory) and item analysis
Also you will want to make sure that your new multidimensional scale shows
evidence of validity (several kinds) and reliability so be sure to examine these
issues and explain how specific information gathered from the above testing
contributes to these concerns
C) Reliability
4) What is reliability and why is it so important What are the different ways reliability can be
assessed and when is each appropriate
15) What does coefficient alpha assess What are the ways coefficient alpha can be increased
C1 Describe and discuss the concept of reliability and all of its various forms
including their assessment When is each form appropriate and what information
is provided by each index
C2 In establishing congruence between multiple measurements we often compute
indices of reliability andor indices of agreement These two types of indices
address very different questions Your task is to 1) Define reliability and
agreement 2) Explain when each is useful using examples in which one but not
the other is appropriate and 3) Briefly describe two reliability indices and two
agreement indices
C3 Explain reliability in terms of the classical test theory What are the
consequences of unreliable measures in hypothesis testing What are the factors
that may affect the reliability of a multi-item scale
IC
C4 Generalizability theory is used within IO psychology more often today
However most researchers continue to use Classical Test Theory
conceptualizations of error to determine reliability What are the implications of
using classical test theory versus generalizability theory to assess reliability
C5 In establishing congruence between measurements we often compute indices of
reliability andor agreement Define reliability and agreement Explain the
differences in reliability and agreement and describe under what conditions
assessing reliability is more appropriate and under what conditions assessing
agreement is more appropriate
C6 Define measurement reliability in terms of a specific measurement theory (eg
true test score theory domain sampling theory generalizability theory IRT)
Discuss the different approaches for estimating reliability and the contexts in
which each might be appropriate Use examples throughout
C7 What are the consequences of unreliability in a measure
C8 What are some of the conditions that might keep the internal consistency (eg
alpha) of a given measure low Is a low alpha always a sign of a problematic
measure
C9 Define reliability Name some methods of calculating reliability How well do
these methods map up with the definition of reliability What is the impact of the
number of test items and sample size on Chronbachs alpha and why would this
effect occur or not occur (Note Do NOT discuss inter-rater reliability)
C10 Schmidt and Hunter (1996) described several types of measures typically used in
organizational research and identified the type(s) of measurement error affecting
each of them in various situations For each measure below indicate the types of
error and sources of error that are most likely to affect it Then indicate what
could be done to reduce errors of measurement andor what can be done to
control for errors statistically
a Supervisor ratings of subordinates job performance
b Self-ratings of ones own job performance
c Self-reports of ones own job-related attitudes
d Sales figures for a salesperson (or production quantity for a production
worker)
d Aptitude tests taken as part of the hiring process
C11 Suppose you had conducted research on the relationship between organizational
commitment and rigidity of organizational structure in 200 firms Your measure
of rigidity was based on number of organizational authority levels and the degree
to which written organizational rules existed and defined role behaviors for
employees Thus an organization with a large number of organizational levels
and specific written policies defining appropriate role behaviors for employees
would score high on rigidity of organizational structure After analyzing your
data you find that there is a statistically significant negative correlation between
commitment and rigidity which is consistent with your hypothesis However the
reliabilities for your two measures are
(1) commitment = 23 (2) rigidity = 83
How should you interpret your results What could you do to fix this situation
Describe the specific steps (in order) you would follow to develop a more
reliable measure of commitment
C12 (a) Define the concept of reliability (of measures) in a clear concise and
accurate manner (b) Provide a formula that expresses the reliability of a measure
in terms of two components of variance ie total variance and the error
variance
D) Multi-level Assessment
D1 One of the major challenges for group-level research is the issue of aggregation of
individual data to the group level
(a) Under what conditions (eg types of data number of raters) should the various
interrater agreement and reliability methods be used (Rwg Kappa and Weighted
Kappa percent agreement average pairwise correlation ANOVA methods
(interclass correlation coefficient WABA)) What are the advantages and
disadvantages of each of the methods
(b) Explain the controversy between Frank Schmidt Larry James and others
regarding the differences between interrater agreement and interrater reliability
Who is right Do the differences matter in research practice
Defend your answers
(c) Review two articles from the organizational behavior literature that have had to
deal with aggregation issues Critique the methods the authors used to make
aggregation decisions
(d) Provide some advice to researchers regarding what they should do if interrater
agreement and reliability indices indicate that it is not legitimate to aggregate their
data
(e) Provide some ideas for avoiding the need to aggregate in group-level research
through creative research methods and measurement strategies
D2 Cross-levelmulti-level research is becoming more evident in the organizational
research literature This type of research raises many issues and presents many
challenges in terms of designing the research measuring variables and collecting
and analyzing the data Assume that you are interested in aggregating data (eg
from the individual to the group or from the firm to the industry) for one or more
variables What are the major issues you will need to deal with
D3 A researcher wants to measure organizational climate for continuous learning
Organizational climate is operationalized as a shared consensual aspect of the
organization -- the shared perception among employees that the organization values
and supports continuous learning Describe how you would measure organizational
climate in this case Specify (a) the level (ie individual group organization) at
which the construct exists (b) the level at which you would measure the construct
and (c) the procedures that you would use to establish that measurement is aligned
with theory (ie the construct validity of the measure)
E) General (Measurement)
E1 Studies in organizational behavior research often rely on single-item measures of
key constructs The use of single-item measures has long been criticized based
on the premise that single-item measures are unreliable However Wanous
(Wanous amp Hudy 2001 Wanous amp Reichers 1996 Wanous Reichers amp Hudy
1997) has recently argued that single-item measures can exhibit adequate
reliability Wanous based this conclusion on a procedure for estimating the
reliability of single-item measures using the classic formula for correction for
attenuation Subsequent studies have yielded mixed results regarding the
conclusions of Wanous (eg Loo amp Kells 1998 Nagy 2002) and the veracity
of the perspective advocated by Wanous remains in question Summarize and
assess the arguments for and against the use of single-item measures and
evaluate the procedure and evidence offered by Wanous regarding the reliability
of single-item measures Based on your assessment and evaluation develop
recommendations regarding the use of single-item measures in organizational
behavior research

E2 Ipsative measures have become prevalent in organizational behavior research
Ipsative measures ask respondents to answer questions relative to one another
such that the scores for all questions sum to the same constant for all respondents
Examples of ipsative measures include rankings Q-sorts and the allocation of a
fixed number of points (eg 100) across a set of response options Ipsative
measures may be contrasted with absolute measures which ask respondents to
answer questions independently from one another Absolute measures are
exemplified by rating scales using an interval or ratio numeric response format
The relative merits of ipsative and absolute measures have been debated for
decades (eg Cornwell amp Dunlap 1994 Hicks 1970 Johnson Wood amp
Blinkhorn 1988 Saville amp Wilson 1991 1992) yet the fundamental issues
underlying this debate have not been adequately addressed in organizational
behavior research For example measures of organizational culture and values
are often ipsative and some researchers advocate these measures over absolute
measures (eg Meglino amp Ravlin 1987 OReilly Chatman amp Caldwell 1991
Ravlin amp Meglino 1987 see also Rokeach amp Ball-Rokeach 1989) Review the
relative merits of absolute and ipsative measures Based on your review which
form of measurement is most appropriate and why Do your conclusions depend
on the construct being measured If so what types of constructs are best suited to
ipsative measures and what types are best suited to absolute measures Next
apply your conclusions to the measurement of culture and values in
organizations What specific arguments have been advanced in favor of ipsative
measures of culture and values How sound are these arguments Should ipsative
measures be used in the study of organizational culture and values If not how
can absolute measures of culture and values be developed that address the
concerns voiced by advocates of ipsative measures Provide a specific example
of the type of measure you would propose

facets of a concept Although such measures are prevalent and in some cases are
advocated (eg Law et al 1998 1999) they can present a variety of conceptual
and methodological problems Describe the specific problems associated with
measures that use items representing different facets of a concept Compare these
problems with the purported advantages of such measures Conclude by

E5 Suppose Roberta Von Eisenbrick is a researcher interested in the consequences of
AFFECTIVE CONFLICT (AC) in decision-making teams She gets access to a
variety of outcomes assessment committees at each of 87 different schools in
the Dallas Independent School District and gains permission to tape-record two
of their meetings (one in February and one in March) Such committees have
been formed to develop quantitative ways to track pursuit of school goals and
provide accountability to local and state governments These are often divisive
teams with heated meetings because what gets assessed is what usually gets
rewarded After both of these meetings the committee members each
fill out a short questionnaire that contains 20 Likert-type items measuring how
much AC occurred (eg People in our group often get angry with each other)
The individual scores are summed across items then averaged across team
members to come up with a group-level AC score for each of the 87 2
meetings The same procedures are followed for a 5-item measure of Group
Cohesiveness (GC) which is predicted to be reduced by higher levels of AC
Roberta also listens to every tape and from her expert judgment she rates each

it
c What is construct validity Discuss how the (un)reliability of the AC measure
could affect the conclusions one would draw from a study involving it and GC In

problems engendered by significance testing and why have these remedies not
been widely adopted

D) ModeratorsMediators
D1 Moderation and mediation provide different ways to model third variable effects
(a) Please define both of these terms (b) Sketch a conceptual model to show how
each relates to main effects (c) Using variables of your choice please write
hypotheses to reflect both (d) Explain how each is tested analytically
D2 Discuss moderators and mediators Provide an example of how (1) a moderating
variable influences the relationship between the independent and dependent
variable and how (2) a mediating variable influences the relationship between
the independent and dependent variable Describe how you would test for both
moderation and mediation using regression
D3 Many theories in organizational research predict that the effects of one variable
on another are moderated by a third variable Such moderator effects are
typically tested by entering the product of two variables as a predictor after
controlling for the two variables that constitute the product Several researchers
have pointed out that this product is often highly correlated with the squares of
the two constituent variables and have suggested that moderating effects may be
tested after controlling not only for the two constituent variables but also their
squares (eg Cortina 1993 Ganzach 1998 Lubinski amp Humphreys 1990
MacCallum amp Mar 1995) Discuss the strengths and weaknesses of this
approach as compared to methods that use only the product term and its
constituent variables Conclude with recommendations as to when and under
what conditions organizational researchers should test moderator effects with the
squares of the constituent variables in the equation

D4 Assume you are interested in studying relationships amongst three variables X
Y and Z Your first hypothesis posits Z as a mediator of the relationship between
X and Y Your second hypothesis posits Z as a moderator of the relationship
between X and Y Draw the figures depicting each of these hypothesized
relationships and describe (make sure to write regression equations) how you
would test each of these hypotheses
D5 The amount of time and effort that the average person pours into his or her job
has risen steadily over the last two decades such that the average person now is
working one more week per year than the average person in the mid 1970s This
steady increase has fueled research interest in the construct of Job Burnout (JB)
which is an emotional and physical exhaustion associated with ones work
Organizational Stress (OS) the perception of greater demands than available
resources in ones work environment is thought to be one of the chief
antecedents of JB However time spent under OS is thought to make its affects
on JB accumulate or worsen Work Role Withdrawal (WRW) the avoidance of
responsibilities or the deliberate reduction of inputs to ones job is believed to be
the chief consequence of JB
a Formally state these ideas as verbal hypotheses as equations and as a complex
directed graph (circle amp arrow diagram)
b Conceptually what is a mediator Define the term and identify the mediator in
your hypotheses in (a) What elements or steps in a study design (not statistics)
that would be helpful for detecting the mediating relationship that was proposed

subdomains of management Further demonstrate your understanding of
moderator variables by picking which variable in (a) is the moderator Show the
moderating relationship in an X-Y (or multi-layered) chart Again what elements
or steps in a study design (not statistics) would be helpful for detecting the
moderating effect implied above

recommendations You conduct a well-designed controlled study (details are unimportant) and discover students who use the new book perform 10 better on a standardized subject
matter exam than those using the old book (p = 027) Both books are readily availabe their prices are almost identical and both are equally acceptable to the instructors What is your recommendation to the chair
F1 Attached is the beginning of an article Your task is to write the results section by
1 making up and reporting plausible descriptive statistics that will help the
reader understand the results of the statistical tests you report and the nature of your
sample (Hint this can be presented in the form of a table)
2 describing and defending your choice of appropriate statistical tests of the
hypotheses and the steps that you would go through in carrying out these tests
3 making up and reporting results of these tests that are consistent with your
descriptive statistics and with any information in the rest of the article about the
results found (Hint this can be presented in the form of a table)
4 describing how well these results provide support for the hypotheses You
may want to note any relevant threats to validity here
Be sure to state any assumptions you make
F2 Assume that the Personnel Manager of a local firm Ms B dFlandres hired you to
analyze some data that her assistants had collected over the past several years The
data consist of (a) job performance ratings that were made in June of 1990 and (b)
scores on 25 predictor variables (eg measures of education job experience job
tenure job aptitude personality) that were measured when the individuals were hired
(between April 1987 and May 1988) She had data from only the 110 subjects (60
males and 50 females) who were hired during the period and were still employed by
the firm One objective of your analysis (analyses) is to determine how well the
performance criterion can be predicted by the predictors What strategy would you
use in analyzing the data Describeexplain (b) Is sample size an issue for your
analyses Explain If it is what will you do to deal with problems stemming from
sample size Assume that no additional data can be collected at this time (c) Some
preliminary analyses that you do reveal that five of the predictor variables correlate
(zero-order basis) about 75 with one another Will this influence the analyses that
you use Will it influence the validity of conclusions derived from your proposed
analyses (d) Ms dFlandres is interested in knowing if the predictor variables are
equally effective in predicting the job success of males and females What analysis
or analyses would you do to deal with this issue
F3 Assume that you have been provided with data on 12 conceptually distinct variables
that are moderately correlated with one another at the empirical level The data are
from students in four different college majors ie astronomy (A) biology (B)
criminology (C) and demography (D) The 12 measured variables fall into the
general categories of mental health (tension emotional withdrawal hallucinations
guilt feelings blunted affect and suspiciousness) and job satisfaction (work itself
supervision co-workers pay promotion prospects and working conditions) Your
task is to determine if the individuals in the four college majors differ from one
another on the 12 measured variables
(a) What statistical technique(s) would you use to test for group differences
Explain Be specific about the procedures(s) that you would use
(b) What statistical estimate would you use to estimate the extent to which the
groups differ from one another Be specific
F4 The following statistical table published in a recent issue of Work amp Occupations
was taken from an article discussing variables influencing resistance and citizenship
behaviors in the workplace Resistance behaviors include playing dumb withholding
effort work avoidance subverting particular managers and sabotage Citizenship
behaviors include cooperation engaging in peer training use of insider knowledge to
facilitate production commitment to organizational goals giving extra effort freely
Both measures are global constructs aggregated to the interval level and
standardized
The table reports the results of a series of ordinary least squares regression equations
with standardized coefficients Explain the meaning of the statistics presented What
do these statistics tell us generally about the relationship between resistance
behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows
Anomie Index -standardized interval level measure tapping multiple dimensions
The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)
F5 Researchers collected data from a sample of 350 companies on the following
variables
size (measured as number of employees)
Business Strategy (a nominal variable with 2 response options low-cost provider or
differentiator)
HR Strategy (a nominal variable with 2 response categories High commitment or
low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

exploratory way Also describe the difference in principal components analysis
(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression

P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation

Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)
Please comment on these restrictions versus access argument Which side do you
take
What are the strengths of SEM Give some examples
What are the weaknesses of SEM Give some examples

firms environmental scanning activity Through previous arrangement Jean has
been working with 5 medium-sized computer hardware and 5 medium- sized
software firms on the west coast Shes been collecting a paper trail of internal
memos reports and phone calls that might measure environmental scanning
activity Shes been finding that the firms in both industries do about the same
amount of scanning (no significant differences) However in the midst of her data
collection Norton announces a merger with Symantec (software) A year later
Jean compares the amount of post-merger environmental scanning in the software
industry with that in hardware industry Just as Jean had hypothesized a t-test
shows a greater amount of post-merger scanning among the software firms She
concludes that her hypothesis was supported mergers of competitors cause an
increase in scanning
Critique the study described above in terms of its design flaws Identify the design
Jean used Briefly allude to problems the study has with external validity but
concentrate on the Cook and Campbell threats to internal validity Provide a
rationale for why each threat is or isnt operating in the study Link each of the
relevant threats to the specific constructs being studied (mergers and environmental
scanning) Finally do a summary evaluation -- what can be learned from this
study
H) Quasi-Experimental Design
H1 The University of Mississippi observed that the graduation rate of students with poor
grades during their freshman year was much lower than those with better grades
Wanting to improve the chances of these low performing students they tested the
effects of a new rule for freshmen The rule stated the following At the end of their
first semester all students with a GPA between 200 and 225 must register for
EDUC 1003 during their second semester Students with a GPA lower than 200
were put on academic probation EDUC 1003 consisted of a course whose objective
was to help students develop good study skills The theory was that poor study skills
were a significant cause of poor academic performance and that study skills could
be learned
They wanted to evaluate the effectiveness of this intervention so they collected data
on the GPAs of students beginning with their first semester and continuing through
to their third semester At that point they wanted to analyze the data to determine
whether the new rule was making a significant difference in the students academic
performance
What is the best way to analyze these data to reach an interpretable conclusion
Describe your approach and then discuss the major threats to validity that it has
Their sample size of students was as follows
Total N= 3454 (these are students who completed all 3 semesters)
Number of students with first semester grades between 200 and 225 (and thus took
EDUC 1003) was 956
H2 A nationwide furniture company wants to determine if a diversity training
program will improve individual sales performance on the floors of its urban retail
outlets A group of 45 salespeople in one city were given two weeks of training
Measures of individual sales performance were taken once two months prior to the
program and once two months after Forty-five salespeople (who did not receive the
training) in a similar city had the same measures taken at approximately the same
points in time The training group increased their average weekly sales from $14000
to $16500 while the non-training group improved theirs from $13000 to $14500
The change for the training group is statistically significant the change for the non-
training group is not
How would the interpretation of these results in this quasi-experimental design
differ from a true experimental design What are the threats to internal validity in
the above study and how might they be operating (be specific) What additional
information and analyses would be useful in controlling for these threats
H3 An accounting firm is interested in determining if a re-training program will reduce
errors made by its audit teams A group of 45 auditors in the home office location
are given two weeks of re-training Measures of the frequency of detectable errors
are taken once two months prior to the program and once two months after Forty-
five auditors in similar office at a branch location have similar measures taken at
approximately the same points in time The training group reduced their average
number of errors per audit from 8 to 3 while the non-training group reduced theirs
from 11 to 9 The change for the training group is statistically significant the change
for the non-training group is not
How would the interpretation of these results in this quasi-experimental design
differ from a true experimental design What are the threats to internal validity in
the above study and how might they be operating (be specific) What additional
information and analyses would be useful in controlling for these threats
H4 Describe the main classes of threats to validity that are found in quasi-experimental
research designs
H5 Dr Delta an organizational development consultant was hired by a firm that has
600 pizza parlors nationwide to assist in implementing organizational changes that
he hopes will result in higher levels of job involvement At the outset of the study
subjects had jobs with very low levels of enrichment and were paid on an hourly
basis He designed an experiment in which stores were randomly assigned to one of
three treatment conditions Condition 1 subjects experienced job enrichment (JE)
and a change to performance-based pay (PBP) Condition 2 subjects experienced
only JE and Condition 3 subjects experienced only PBP The parlors were
sufficiently far apart from one another and communication among the parlors so
poor that subjects in any parlor were totally unaware of changes made in other
parlors At the end of 18 months he measured the job involvement levels of workers
and then tested for differences between the three conditions using a standard one-
way analysis of variance In view of Dr Deltas design answer the following
questions
How sound is Dr Deltas design Comment on the weaknesses of the design
I) Interrupted Time Series Design
I1 What threats to internal validity are and are not ruled out by an interrupted time series
design that includes the introduction of a treatment and its removal at a subsequent
time period List and explain In the process be certain that you provide a diagram
that illustrates such a design
J) Validity Some Questions are about the validity of a measure others about experimental validity)
10) Identify four threats to internal validity and briefly describe what they mean
J1 It was some time ago that the tripartite view of validity was abandoned in favor of a
unitarian view in which different evidentiary bases for validity might be put forward
Binning amp Barrett (1989) represent an attempt to place multiple evidentiary bases into a
single framework Cook amp Campbell (1979) describe four aspects of validity but they
arent really meant to represent evidentiary bases Adding to the confusion is the fact
that while Binning amp Barrett and Cook amp Campbell use some of the same terms these
two pairs of authors clearly mean different things by these terms and intend for them to
be used in different ways Your task is to 1) Describe the evidentiary bases discussed
by Binning amp Barrett 2) Describe the aspects of validity described by Cook amp
Campbell 3) Describe the similarities and differences between the two lists including
the different purposes served by the two lists and 4) Present a single framework that
incorporates both This last task is the most important of the four
J2 What are the types of validity How would each affect an empirical study IC
J3 Define both internal and external validity Which is more important (it is not okay to
say that they are equally important) Defend your reasoning
J4 Why might someone argue that the construct validity of a measure can never really be
established
J5 Describe each of the following forms of validity content convergent discriminant
criterion-related and construct How is each assessed How do they related to each
other Which is most important (Make sure you defend your answer)
J6 Define and explain 6 of the 8 types of validity listed below and describe the type(s) of
information each provides Choose one specific type of study as an example (eg
cross-sectional study experiment quasi-experiment simulation ethnography etc) and
compare and contrast the usefulness and importance of each type of validity for that
type of study
-- Concurrent validity
-- Construct validity
-- Content validity
-- Convergent validity
-- Discriminant validity
-- Statistical conclusion validity
-- Internal validity
-- External validity
J7 Designing empirical research has been called making a series of trade-offs
Unfortunately decisions that are made to increase one desired quality (like internal
validity) can also decrease another desired quality (like external validity) For each of
the issues below discuss the concerns involved (ie the trade-off) and identify the
qualities that are being increased or decreased
a laboratory vs field study
b using a 5-item measure vs a 1-item measure
c using a student sample vs a sample of full-time employees
d using a sample of employees from one company of 5000 vs 500 employees from
each of 10 companies
e collecting your data using one method vs collecting your data using multiple
methods
J8 There are four major types of validity in social science internal validity external
validity construct validity and statistical conclusion validity Please address the
following three issues concerning validity
a What is the meaning of the four major forms of validity (ie internal and external
validity construct validity statistical conclusion validity)
b Are there trade-offs that can or must be made among the four types of validity
d Describe how the concept of validity varies across the research traditions of
experimental vs observational research
IC
J9 The quality of research is often assessed by examining validity issues As you are
aware there are numerous typesforms of validity (eg internal and external validity
construct validity statistical conclusion validity) These types of validity address
different aspects of the research process For this question please address the following
issues
a What is the meaning of the four major forms of validity (ie internal and external
validity construct validity statistical conclusion validity)
b Should there be a priority among these forms of validity If yes why If no why not
c Does the concept of validity vary across research traditions (ie experimental vs
observational research) If yes why If no why not
J10 External validity has received considerable attention in the social and behavioral
sciences Some researchers argue we are too concerned with the external validity of our
findings while other researchers argue that we are too unconcerned with external
validity Several points of view have been developed to explain what is external
validity When answering this question please be sure to address at least the following
issues
a Compare and contrast alternative conceptualizations of external validity
b Some researchers have argued that the role of external validity is invariant across
research traditions (ie experimental vs observational research) Defend the
perspective that the role external validity is invariant across these two research
traditions In addition present the weaknesses of this perspective
J11 In designing a research study researchers must consider trade-offs between internal and
external validity Explain what is meant by internal validity and external validity What
is the nature of these trade-offs How would you evaluatedetermine which is more
important internal or external validity for a particular study Why is this such an
important issue in organizational studies
J12 A researcher conducted a quasi-experiment to test the effects of participative decision
making (PDM) on job attitudes of employees Employees from different departments in
a large organization were assigned to either a treatment group (PDM implemented) or a
control group (no PDM) Random assignment was not possible because of work
schedules coordination of tasks etc Thus the design can be considered an untreated
control group design with pretest and posttest and is represented as follows (where
O=observation X = treatment)
________________

The results of the experiment are presented in the graph below [no graph provided]
The dependent variable is job satisfaction and is measured on a 100 point scale (with
100 being extremely satisfied) How amenable are these results to causal interpretation
What is (are) the major threat(s) to internal validity B if any B for this type of design
given these results What steps can be taken to assess the extent of this (these)
threat(s)
K) Data Collection Methods
14) Describe the various methods of data collection (eg survey interview observation etc)
available to a social scientist What are the advantages and disadvantages of each relative to
each other
K1 Within micro organizational research much criticism has been raised concerning
the reliance on self-report survey data What potential problems does self-report
survey research raise How big of a problem do you think this is
K2 There are a number of methods for collecting data (eg survey interview archival
etc) that are available to a social scientistorganizational researcher Discuss each in
terms of their strengths and weaknesses both on their own and in comparison to one
another
K3 Pick an important construct in your favorite area of management research for which
there is some controversy about how it should be measured or operationalized (eg
environmental munificence or growth need strength) Give the prevailing verbal
definition of the construct and analyze the measurement controversy from two
broad angles First discuss how the controversy may or may not stem from claims
about how one measure is better or worse than another because it (or the other) is an
(a) archival record (b) direct observation (c) social report or (d) self-report That is
what are the relative strengths and weaknesses of each of these types of
measurement for the construct youre discussing Second discuss the construct
validity of the most commonly used measure(s) of this construct To answer this
second part you need to discuss just what construct validity is and how it can or
cannot be demonstrated In the situation you describe what could be done to
demonstrate or improve the construct validity of existing measures
K4 Interviewing in some form has been the workhorse for data collection in a variety
of research traditions positivistquantitative ethnographic feministpost-modernist
and increasingly historical research While each tradition elicits information from
respondents the goals and processes involved in interviewing vary considerably
across research traditions Discuss the purposes of the interview the relationship
between data and theory the roles assumed by the interviewer and the respondent
and the relevant criteria for assessing the validity and reliability of the information
obtained In addition compare and contrast the use of the interview as a data
collection method in the positivistquantitative tradition with its use in one of the
alternative traditions
L) Common Method Variance
L1 Many of us have had concerns about the reviews of our survey research which
suggest that data analyses of surveys are biased because of common method
variance effects of individual differences such as negative mood negative
affectivity and social desirability and the reliability and validity of the constructs
we are attempting to measure Define how these problems affect a research issue in
organizational behavior and the steps that might be taken to minimize such potential
criticisms of papers based on analyses of self-reported data through survey
instruments
L2 In a series of papers by Spector (1994) Schmitt (1994) and Howard (1994)
published in the Journal of Organizational Behavior arguments were provided for
and against the use of self-report questionnaire measures One of the issues
discussed that could limit conclusions drawn from relationships observed using self-
report measures was method variance What is meant by method variance what are
its sources and what impact is it expected to have on research findings
M) Sampling
M1 The manufacturing census samples all plants of 250 employees or more For
plants of 5-249 employees it takes a size proportional sample Plants of 1-4
employees are not sampled What challenges does this sampling method provide
to researchers What could you do to account for these problems if you were
TH
studying organizational (not plant) growth
M2 New York State has approximately 250000 employees in over 70 state agencies
commissions and boards ranging in size from approximately 50 to over 5000
employees Assume that you wanted to draw a representative sample of 1000
employees Describe two ways that you could draw such a sample and briefly
describe the advantages and disadvantages of each of these sampling approaches
IC
M3 The director of a national non-profit agency with approximately 10000
employees located primarily in regional offices in each of the 50 states the
United States has approached you and asked you to develop a study
(organizational survey) of organizational culture within the agency The agency
is about to embark on a variety of change initiatives including developing team
structures and the study is meant to examine various elements of organizational
culture that are potential barriers to change The director has indicated that he
would like to have the data analyzed at both the individual and office level of
analysis Because of funding limitations the agency will only be able to send the
survey to 1000 employees The director has indicated that there are three ways
of sorting employees all employees listed alphabetically all employees listed
alphabetically by state and all employees listed alphabetically by region (there
are between five and ten regions per state) Given these three ways of sorting
employees describe at least three different sampling approaches and the
advantages and disadvantages of each
M4 In your role as Teacher of Organizational Studies you are asked to prepare a
tutorial for beginning doctoral students on sampling design Assume that this
tutorial is part of a basic class in research design and that students in this class
have had a basic statistics course up to and including multiple regression Your
tutorial should focus on briefly defining and explaining the differences between
probability and non-probability samples You should make sure to present and
describe several types of probability samples (eg random systematic
stratified etc) and non-probability samples (eg convenience snow-ball quota
etc) and discuss general principles for when to use a probability vs a non-
probability sampling design For each sampling design you should also provide
at least one clear example of a situation where this type of sampling design is
appropriate
N) Cross-Cultural Research
N1 Discuss the problems in conducting cross-culturalnational comparison in terms
of (1) conceptualization and (2) research design and data collection
Define the three levels of measurement invariance How would the problems that
you have identified in part (a) affect measurement invariance How would you
examine measurement invariance by confirmatory factor analysis
TH
N2 Explain why using national boundaries as independent variable in cross-cultural
studies may not be appropriate in terms of theory and research methods What
alternative ways would you recommend
IC
O) General
O1 In your readings research has been described as choices among conflicting goals
(desiderata) For instance when choosing among research strategies a researcher
must choose among the desiderata of precision realism and generalizability The
trade-offs among desiderata occur for all aspects of research that is for the selection
of theories the treatment of independent variables research strategies the selection
of the problem to study rules of evidence for determining the meaningfulness of a
research finding and even the frameworks that describe the research process
Discuss what you see as the major trade-offs for each of the following aspects of
research That is discuss what you see as the major strengths and weaknesses
(advantages and disadvantages) of each aspect
a The trade-offs between internal and external validity
b The manipulation of the independent variable vs the observation of the
independent variable
c Basic vs applied research
3 DESIGNING A RESEARCH STUDY
A) General (Research Design)
3) Why is control so important in research design What are the different ways it can be
achieved (give a brief description of each control method) What are advantages and
disadvantages of each
A1 It has become almost a truism to note that the choice of methods influences theory
and questions data and conclusions (the causal direction might also be reversed)
Briefly discuss how the methods used have influenced research in any two of the
following areas leadership power and politics organization culture organization
justice Compare and contrast as possible Suggest some potentially fruitful
methodological directions for future work in these same topical areas and dont be
shy about reflecting on broader issues of how the field of organizational behavior
constructs its realities Lastly tie your discussion and reflections back to your own
future as a researcher what lessons or guidance do you derive from your
understanding of these issues
A2 Characterize as fully as possible what you see to be the methodological approach or
approaches in strategic management research Is there a dominant method or a wide
variety Discuss the reasons for the situation What are the advantages benefits etc
of the approach(es) in use What assumptions (ontological epistemological
ideological) do they embody Are current efforts ideal or at least adequate Are
there other approaches that could be useful If so how might researchers be
encouraged to use these as well If you see no advantage to more variety in
methodological approach support that point of view
A3 Describe a research question or area of interest to you and why you think it is not
only of interest but significance Using your understanding of research methodology
describe two ways of pursing the question that are as divergent on as many
dimensions as you can imagine Describe the advantages and disadvantages of each
approach How strong a link or fit is there between a research question and a
method
A4 In his 1957 article entitled The two disciplines of scientific psychology Cronbach
discussed the assumptions goals and methods used in experimental methods and
correlational methods in psychology
a According to Cronbach what is the main difference between the two disciplines
b Discuss the strength and weaknesses of each discipline
c What if anything could be done to improve the situation
B) Designing a Research Study
B1 Cook and Campbell describe the experiment as the research design with the
greatest methodological rigor However given the constraints present in most
organizations I-O Psychologists cannot often conduct experiments in applied
settings and must settle for techniques with less control than experiments
Describe a study to investigate the relationship between participation in a
supervisor training program and work performance which could realistically be
conducted in an organization If an experiment is not possible describe how you
would go about maximizing your ability to draw valid conclusions from your
design
B2 The XYZ Co has recently developed a sexual harassment web-based training
program The developers claim the program will cut training time and costs and
will be as effective or more effective than classroom-based sessions They
believe that this will be due to the increased availability of the program and the
ability for participants to review program material on demand Before the XYZ
Co developers launch this product they want you to determine if their claims
have merit Explain how you would design a study for this purpose
B3 Research suggests that demographic diversity improves group creativity but
reduces group efficiency Some argue that demographic diversity is just a proxy
for value and experience diversity and that demographic diversity on its own is
meaningless Design a test to settle this argument
TH
B4 E-mail has become a common form of communication in organizations and is
used for both formal and informal communication Because it has become so
IC
popular some people complain that the frequent use of e-mail leads to
miscommunication because they receive communications in e-mail that should
be accomplished through face-to-face or telephone conversations where there is
an opportunity for interaction You are interested in looking at this
phenomenon You are most interested in describing how e-mail is used for both
formal and informal communication and in examining the effect of the e-mail
use on organizational communication effectiveness Design empirical research
to address those issues
Describe your study in detail thoroughly explaining the research design
sampling plan data collection procedures ethical issues and proposed data
analysis for your research design Be sure to discuss the internal and external
validity of your research Which validity threats are ruled out and which
remain
REMEMBER Be thorough Your research design should demonstrate that you
are a competent researcher who is knowledgeable about the proposed research
methodology or methodologies Therefore be sure that you carefully describe
and give technical explanations for each component of your research
B5 Choose a specific situation involving employee selection eg artists for an
advertising agency (a) What strategy would you use in selecting the selection
measures (b) How would you combine the measures eg which measures
would you combine in a compensatory manner and which is a noncompensatory
manner (c) How would you assume test fairness defining various measures of
the term (d) How would you make final selections (e) How would you
validate your procedure (f) What considerations would enter in if your
company were too small to provide validation data (g) What difference would
it make if you were developing a procedure for deciding whether trainees
should be promoted as opposed to making new hires Please note--emphasize
but do not limit yourself to statistical issues
B6 There is evidence in the marketing literature of a non-monotonic relationship
between the expectations that customers have for retail service and their
eventual level of satisfaction with that service That is as a customers
expectations for service increase so does their eventual service satisfaction --
up to a point After that point the greater the expectations the lower the
eventual satisfaction Develop a hypothesis that includes a moderator variable
that might account for this evidence Give some reasonable rationale for it State
your hypothesis verbally as an equation as a directed graph (circle amp arrow
diagram) and as an X-Y function chart Discuss how it would or would not be
possible or useful to test your hypothesis via a laboratory experiment In your
discussion cover how and why a researcher could (not) manipulate the
independent constructs involved (mode X) whether or not random assignment
to conditions (mode R) is possible (including how may conditions would be
necessary) which alternative constructs could or could not be controlled (mode
K) and which constructs should be measured (mode Y)
B7 Assume you are the chairperson of a committee that must evaluate
undergraduate programs at your university Your task as chairperson is to
devise an approach (a design a research strategy a set of measures) that will
allow you to evaluate undergraduate programs Make sure that your approach
can be used in the future and at other comparable universities When developing
your plan be sure to address at least the following issues
a the type of design you would select Compare and contrast the selected design
with another possible design
b the type of research strategy you would select Compare and contrast with
another possible strategies
c discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
B8 Assume you are an organizational research design expert assigned to the
Strategic Planning Department of a large multi-national manufacturing firm
The Department has developed a new PC-based software package called
STRATPACK The software (and a one-week training course to learn how to
use it) is intended to improve the long-range planning ability of middle and
upper-level managers
Your job as research design expert is to devise research (a design a research
strategy a set of measures) that will allow you to evaluate the effectiveness of
the STRATPACK program Describe a research design for evaluating the
program Make sure that your research approach can be used in the future and at
all sites in the company When developing your plan be sure to address at least
the following issues
a discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
b the type of design you would select (eg a design where you manipulate the
independent variable versus observe the independent variable) Compare and
contrast the selected design with another possible design
c how your design deals with the major forms of validity Be sure to examine at
least internal external and construct validity
B9 Assume you are a consultant hired to evaluate the effectiveness of an industrial
safety program undertaken by a large manufacturing organization The safety
program is a behavioral one that provides rewards such as monetary bonuses or
extra paid vacation days for safety behaviors in terms of accident-free days
weeks etc Your task is to devise an approach (a research strategy a design a
set of measures and a general analysis strategy) that will allow you to evaluate
the safety program Because of the potential for the influence of many
extraneous variables on any safety program it is difficult to design research a
single cross-sectional study than can evaluate the impact of a single safety
program How would you design a study to evaluate the impact of the safety
program When developing your plan be sure to address at least the following
issues
a the type of research strategy you would select Compare and contrast with
another possible strategies
b the type of design you would select Compare and contrast the selected design
with another possible design
c discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
B10 One of the most important areas of research is forecasting of human resources
needs based on strategic positions of organizations For example NY State must
carefully forecast its human resources needs as it proceeds with significant lay-
offs of state employees Future human resources needs are generally evaluated
by either statistical ie regression or simulation or clinical judgment i e
supervisors judgments methods
a Design a single study that addresses the empirical question of whether
statistical or judgmental methods are better for forecasting human resources
needs You may discuss a program of research but please be quite specific in
your description of the first study
b What are the critical methodological issues in doing this kind of research
c What are the critical applied (or practical) issues in doing this research
d Are the issues in b and c related
B11 In the past decade computinginformation technology has changed many
aspects of organizational life For example the technology can make increased
decentralization possible by improving communication between central offices
and field offices Computer networks and word processors can enhance group
empowerment by making it possible for team members to create and edit
written group products quickly even if the individuals are at different locations
Some have argued that computinginformation technology will foster the
paperless productive office nevertheless others argue that the technology only
increases paper and reduces office productivity You are applying to the
National Science Foundation for a grant to conduct research that examines the
impact of computing information technology on organizational decision
processes The NSF application procedure imposes five basic requirements that
your research design must fulfill in order to receive funding Note A very
significant factor affecting NSF grant decisions is a clear demonstration that the
researcher is knowledgeable about the research methodology used Write your
response to each of the following five grant requirements Be sure not only to
respond to the requirement but also to demonstrate your research
competence
1You must design a study that uses two different methods
(interviewobservation survey experiment or quasi-experiment) Describe your
two methods in detail and provide a rationale for the key elements (eg
sampling data collection proposed analysis) of your methods Be sure to
discuss and evaluate the internal and external validity of both methods
2 As part of your research design you must select a conceptual (latent) variable
central to your proposal (use centralization of decision making as your
variable) and describe how you will develop your own measure (You may not
simply use off the shelf instruments)
3 You must describe how you will test for the reliability of the measure
(centralization of decision making) you developed in step 2 The NSF insists
that you describe how you will evaluate both the temporal stability and the
internal consistency of your measure Be sure to discuss what temporal stability
and internal reliability mean and how they are related
4You must describe how you will assess the validity of the measure
(centralization of decision making) you developed in step 2
5 NSF requires a brief statement and defense of the philosophy of science
underlying your research Discuss your position and show how your research
design is consistent with your philosophy
B12 Many organizations in the United States economy have installed some form of
Empowered Teams as an alternative or supplement to traditional bureaucratic
structure Preliminary evidence of the effectiveness of empowered teams
however is mixed--some organizations have claimed success and others have
reported failures The evidence however is predominantly anecdotal--written
for trade magazines by the organizations themselves There are few rigorous
empirical studies assessing the effectiveness of empowered or self-managed
teams You are applying to the United States Department of Labor (USDOL) for
a grant to conduct research that examines the effectiveness of empowered
teams The application procedure of the USDOL imposes three requirements
that your research design must fulfill in order to receive funding Write your
response to each of the three grant requirements The importance of each section
is implied by the evaluation points allocated by the USDOL to each of the three
requirements given in parentheses
1 (50 points) Your study design for assessing Empowered Team effectiveness
must use two different methods (interview observation archival analysis
survey simulation experiment or quasi-experiment) Describe in detail and
thoroughly explain the sampling plan instrumentation data collection
procedures and proposed data analyses for both methods Be sure to discuss the
internal and external validity of both methods and how the two methods
complement one another
2 (30 points) As part of your research design you must select one conceptual
(latent) variable central to your proposal and describe how you will develop
your own operationalization of the measure (You may not simply use off the
shelf instruments) Use the concept of group morale to demonstrate your
operationalization methodology Be sure to explain very explicitly to the
USDOL how you will assess the validity and reliability of the group morale
measure you are developing
3 (20 points) The USDOL traditionally has funded research conducted only
within the general paradigm of logical positivism but now is more open to other
research paradigms as well Your grant proposal must provide a statement and
defense of the explicit philosophy of science underlying your research Describe
your philosophy of science and show how your research design is consistent
with your philosophy
REMEMBER Be thorough You not only must design effective research but
you also must demonstrate to the USDOL that you are a competent researcher
It is absolutely vital to the USDOL that the principal researcher is
knowledgeable about the proposed research methodologies Therefore be sure
that you always carefully describe and give technical explanations for each
component of your research design and explain all technical terms (eg
Cronbach alpha KR-20 Likert scale)
B13 Assume that you are working as part of a research team that is responding to a
RFP (Request for Proposals) from a funding agency for research on work
socialization and newcomer adjustment The RFP calls for rigorous field
research that tests the effectiveness of theory-based interventions aimed at
facilitating the adjustment of new organizational members to complex andor
stressful work conditions The major goal of your teams research is to test the
effectiveness of a self-regulation intervention which trains newcomers to
identify and use relevant social information and cues to regulate work behavior
Your group hypothesizes that self-regulation training will be more effective
than other common treatments or interventions (eg realistic job previews
institutionalized socialization tactics)
You have been included in the team because of your methodological expertise
Your role is to design a rigorous field experiment or quasi-experiment to test he
effectiveness of the self-regulation training program REMEMBER THE
MAJOR CRITERION FOR FUNDING IS THE RIGOR OF THE RESEARCH
DESIGN Design a field study to include in the grant proposal Your proposal
should contain the following two sections
1 Study Design Construct and describe in detail an experimental or quasi-
experimental design to test the effectiveness of your intervention Describe in
detail the experimental groups (including how they will be constructed) the
research setting the sampling plan for study participants the treatment
manipulation and the data collection procedures Also indicate any control or
nuisance variables that may be measured
After describing the procedures write a justification of the design What threats
to validity does it rule out or limit and what threats to validity remain
II Measurement Describe the steps you would take to achieve valid and
reliable measure of the latent (conceptual) variable worker adjustment Your
team feels that as part of the proposal you must develop an original
operationalization of adjustment (thus you cannot simply use existing off the
shelf measures) Indicate in adequate detail how you would operationalize the
measure and indicate how you would demonstrate reliability and validity
B14 In describing their notion of the collective mind Karl E Weick and Karlene H
Roberts note Our focus is at once on individuals and the collective since only
individuals can contribute to a collective mind but a collective mind is distinct
from an individual because it inheres in the pattern of interrelated activities
among many people (p 360) Collective mind is not indexed by within-group
similarity of attitudes ideas or activities A collective mind is one in which
many people or many groups integrate their different attitudes ideas and
activities heedfully As Weick and Roberts note People act heedfully when
they act more or less carefully critically consistently purposefully attentively
studiously vigilantly conscientiously pertinaciously (p 361)
The idea of the collective mind as heedful interrelating is developed in the
following excerpt When people make efforts to interrelate these efforts can
range from heedful to heedless The more heed reflected in a pattern of
interrelations the more developed the collective mind and the greater the
capability to comprehend unexpected events that evolve rapidly in unexpected
ways When we say that a collective mind comprehends unexpected events we
mean that heedful interrelating connects sufficient know-how to meet situational
demands For organizations concerned with reliability those developments
often consist of unexpected non-sequential interaction (p366)
An example of heedful interrelating occurs as a pilot lands herhis aircraft on the
deck of an aircraft carrier The pilot does not actually land She is recovered
A recovery is an interrelated set of activities among air traffic controllers
landing signal officers the control tower navigators deck hands the helmsman
driving the ship etc These activities can be interrelated more or less heedfully
depending on the care with which the different units contribute represent the
situation and subordinate their activities to the single purpose of successful
recovery (p 363)
You are to design a two-part study
Part I You are to design a measurement study which assesses heedful
interrelating (ie collective mind) with a quantitative measure in a replication
of an aircraft carrier flight deck or other situation of your choosing Describe
your research strategies including operationalization of the variable selection of
the sample subjects data collection data analysis and so on for the purpose of
developing a measure of heedful interrelating
Part II Using the measurement tool developed in Part I and any other tools as
needed describe how you would design a study which would compare heedful
interrelating across organizations Choose at least one macro-organizational
variable (eg technology environment) as your basis of comparison Here you
must describe how you would make your selection of organizations to be
compared your data collection procedure data analysis and so on
B15 Many organizations in the United States have installed cross-functional teams to
counteract the silo mentality of traditional bureaucratic structure Preliminary
evidence of the effectiveness of cross-functional teams however is mixed --
some organizations have claimed success and others have reported failures The
evidence moreover is predominantly anecdotal--written for trade magazines by
the organizations themselves Since there have been few rigorous empirical
field studies assessing the effectiveness of cross functional teams the National
Science Foundation has decided to fund research on the topic
Assume that you are submitting a research proposal to NSF for a grant to
research the effectiveness of cross-functional teams Describe in detail and
thoroughly explain the research design sampling plan data collection
procedures ethical issues and proposed data analysis for your research design
Be sure to discuss the internal and external validity of your research Which
validity threats are ruled out and which remain NSF also requires that you
provide a statement and defense of the explicit philosophy of science underlying
your research Describe your philosophy of science and discuss how your
research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but
you must also demonstrate to NSF that you are a competent researcher It is
absolutely vital to NSF that the principal researcher (you) is knowledgeable
about the proposed research methodologies Therefore be sure that you always
carefully describe and give technical explanations for each component of your
research design and explain all technical terms (eg Cronbach alpha KR-20
Likert scale)
B16 Assume that you are submitting a research proposal to the Department of
Commerce (DoC) for a grant to research the effectiveness of virtual work teams
A virtual work team is a leaderless collection of individuals who are
geographically separate from one another and share their expertise using
internet media such as a listserver or Lotus notes The DoC requires that the
researcher use both qualitative and quantitative methods to gather data Describe
in detail and thoroughly explain the research design sampling plan data
collection procedures ethical issues and proposed data analysis for your
research design Be sure to discuss the internal and external validity of your
research Which validity threats are ruled out and which remain The DoC also
requires that you provide a statement and defense of the explicit philosophy of
science underlying your research Describe your philosophy of science and

5 MEASUREMENT
A) Measurement Terms
A1 There are four levels of measurement rigor in management research Discuss each
one What properties do measurements at each level have (ie how much
information do the numbers from each level of measurement convey) How can the
numbers be changed (transformed) and still retain the properties of their
measurement level Pick one construct from a favorite research domain and give an
example of an operationalization of that construct at each of the four levels of
measurement rigor (provide arguments about why you think those examples reflect
each level) Lastly treat each examplelevel as a dependent variable in some
statistical analysis Given an example of a statistical technique appropriate for
analyzing data at that level of measurement rigor
A2 Define (and discuss important features or issues concerning) the following
constructs measurement (Define any six terms)
1 Construct validity 6 Item analysis

idea of how many dimension the construct has
b) Suppose you have developed an instrument consists of 20 questions
measuring 4 dimensions (5 items per dimension) from (a) You collected data
from another 300 real estate agents to validate your instrument Explain how
TH
you would use structural equations model (SEM) to examine the reliability and
validity of the instrument What are other concerns about reliability and validity
that are not addressed by this approach
B2 The research and business world have been fascinated with the concept of
organizational culture However operationalizing this construct has been a
difficult task Discuss the ways in which the construct has been operationalized
(eg technique static v dynamic sample selection generalizability) Critically
analyze each of these methodologies Then choose a methodology you would
use to examine organizational culture and defend your choice Describe how
you would study culture and what more would be known about culture as a
result of your study
B3 Suppose you are setting out to develop a new measure of a construct You want
this measure to be used in survey research and you want to establish its validity
and reliability Your goal is to have at the end of the process a measure that is
defensible and likely to be widely accepted by other researchers studying that
construct What steps would you take to conduct such a program of research
For each step explain the purpose of that step explain why that step is
important explain what methods and statistical procedures you would employ at
each step and explain what evidence you would hope to gather at each step
B4 Assume you are interested in constructing a new measure of (fill in with a
relevant variable from your field) Detail the major concerns that need to be
addressed and the steps that need to be taken in working toward validating this
new measure
B5 Assume that you recently read an article on workplace violence which you
found very interesting The authors argued that one of the predictors of
workplace violence was a construct called propensity to be violent and used a
one-item measure as follows How likely are you to become violent when
provoked You had serious doubts about the authors measure and decided to
develop your own
(a) How would you go about developing items to measure propensity to be
violent
(b) How would you determine whether the instrument was reliable
How would you determine whether the instrument was valid
B6 A concern in organizations is retirement of baby boomers within the next 5 -
10 years This concern is focused on the loss of older employees with skills
critical to the core business functions of organizations In order to continue to
have employees with those critical skills it seems necessary to retrain some
older workers However past practice in most organizations has been not to
retrain older workers for a variety of reasons mostly financial A researcher
working for the Human Resources Department of a large corporation - 13500
employees in 12 different plant locations - hypothesizes that the major reason
for not retraining older workers is ingrained in the culture of the corporation
IC
The researcher feels that older workers are not as highly valued as younger
workers in terms of their potential usefulness after retraining The researcher
searched the literature but found nothing in the existing literature to measure
the cultural value construct What should the researcher do to establish a reliable
and valid self-administered paper and pencil measure of this construct namely
the value of retraining older workers

determining the level of centrality of decision making in the organization
Describe and justify the steps you might follow to develop an operationalization
of the concept of technological complexity What standards would you use to
determine if your operationalization is valid
B8 Organizational researchers have several strategies available to them for
gathering information (eg self-report measures archival measures direct
observation and trace measures) Assume that you are going to conduct
empirical research to assess the role that the structure of the organization plays
in determining the level of organizational effectiveness Briefly review the
strengths and weaknesses of the basic strategies (that is self-report measures
archival measures direct observation and trace measures) for measuring
organizational effectiveness Next describe and justify the steps you would
take to develop an operationalization of the concept of organizational
effectiveness What standards and procedures would you use to determine if
your operationalization is valid
B9 One of the most important topics of recent research has been stress in the work
place One of the most important problems with understanding this literature is
the varying definitions and measurement of this construct Suppose you had
decided to investigate the relationship between stress at the work place and dual
career family happiness
a Since there are multiple ways to measure stress in the work place describe
two ways to do this Hint - avoid using two self-report measures
b Describe how you would decide on the best single measure In doing so
describe the steps you would take in evaluating your measure Be sure to define
your meaning of validity and reliability It is important that your measure have
all the necessary psychometric characteristics so that other scientist can trust the
results of your research
c Be certain that you answer the question Validity for what
d In order to understand the results of your study you need to compare your
measure of stress at work with other measures of this construct How would you
do that
B10 Assume that you have been hired by a national survey research company
Shash Inc to write items that will be used in a national survey of attitudes

impact of interpersonal trust on organizational decision making Describe and
justify the steps you might follow to develop an operationalization of the
interpersonal trust concept

operationalization is valid and reliable
How would you assess the construct validity of such a measure
Discuss issues concerning the level of observation of your measure and level of
analysis of the data
B13 Assume you are interested in developing a new scale to measure construct X
Further assume that you have used previous literature and your own conceptual
development to delineate 2 dimensions of X specifically XF1 and XF2
Describe the steps you would go through in developing testing and evaluating
this new scale With regard to testing and evaluating be sure to consider the
role of factor analysis (both exploratory and confirmatory) and item analysis
Also you will want to make sure that your new multidimensional scale shows
evidence of validity (several kinds) and reliability so be sure to examine these
issues and explain how specific information gathered from the above testing
contributes to these concerns
C) Reliability

assessed and when is each appropriate
15) What does coefficient alpha assess What are the ways coefficient alpha can be increased
C1 Describe and discuss the concept of reliability and all of its various forms
including their assessment When is each form appropriate and what information
is provided by each index
C2 In establishing congruence between multiple measurements we often compute
indices of reliability andor indices of agreement These two types of indices
address very different questions Your task is to 1) Define reliability and
agreement 2) Explain when each is useful using examples in which one but not
the other is appropriate and 3) Briefly describe two reliability indices and two
agreement indices
C3 Explain reliability in terms of the classical test theory What are the
consequences of unreliable measures in hypothesis testing What are the factors

true test score theory domain sampling theory generalizability theory IRT)
Discuss the different approaches for estimating reliability and the contexts in
which each might be appropriate Use examples throughout
C7 What are the consequences of unreliability in a measure
C8 What are some of the conditions that might keep the internal consistency (eg
alpha) of a given measure low Is a low alpha always a sign of a problematic
measure
C9 Define reliability Name some methods of calculating reliability How well do
these methods map up with the definition of reliability What is the impact of the
number of test items and sample size on Chronbachs alpha and why would this
effect occur or not occur (Note Do NOT discuss inter-rater reliability)
C10 Schmidt and Hunter (1996) described several types of measures typically used in
organizational research and identified the type(s) of measurement error affecting
each of them in various situations For each measure below indicate the types of
error and sources of error that are most likely to affect it Then indicate what
could be done to reduce errors of measurement andor what can be done to
control for errors statistically
a Supervisor ratings of subordinates job performance
b Self-ratings of ones own job performance
c Self-reports of ones own job-related attitudes
d Sales figures for a salesperson (or production quantity for a production
worker)
d Aptitude tests taken as part of the hiring process
C11 Suppose you had conducted research on the relationship between organizational
commitment and rigidity of organizational structure in 200 firms Your measure
of rigidity was based on number of organizational authority levels and the degree
to which written organizational rules existed and defined role behaviors for
employees Thus an organization with a large number of organizational levels
and specific written policies defining appropriate role behaviors for employees
would score high on rigidity of organizational structure After analyzing your
data you find that there is a statistically significant negative correlation between
commitment and rigidity which is consistent with your hypothesis However the
reliabilities for your two measures are
(1) commitment = 23 (2) rigidity = 83
How should you interpret your results What could you do to fix this situation
Describe the specific steps (in order) you would follow to develop a more
reliable measure of commitment
C12 (a) Define the concept of reliability (of measures) in a clear concise and
accurate manner (b) Provide a formula that expresses the reliability of a measure
in terms of two components of variance ie total variance and the error
variance
D) Multi-level Assessment
D1 One of the major challenges for group-level research is the issue of aggregation of
individual data to the group level
(a) Under what conditions (eg types of data number of raters) should the various
interrater agreement and reliability methods be used (Rwg Kappa and Weighted
Kappa percent agreement average pairwise correlation ANOVA methods
(interclass correlation coefficient WABA)) What are the advantages and
disadvantages of each of the methods
(b) Explain the controversy between Frank Schmidt Larry James and others
regarding the differences between interrater agreement and interrater reliability
Who is right Do the differences matter in research practice
Defend your answers
(c) Review two articles from the organizational behavior literature that have had to
deal with aggregation issues Critique the methods the authors used to make
aggregation decisions
(d) Provide some advice to researchers regarding what they should do if interrater
agreement and reliability indices indicate that it is not legitimate to aggregate their
data
(e) Provide some ideas for avoiding the need to aggregate in group-level research
through creative research methods and measurement strategies
D2 Cross-levelmulti-level research is becoming more evident in the organizational
research literature This type of research raises many issues and presents many
challenges in terms of designing the research measuring variables and collecting
and analyzing the data Assume that you are interested in aggregating data (eg
from the individual to the group or from the firm to the industry) for one or more
variables What are the major issues you will need to deal with
D3 A researcher wants to measure organizational climate for continuous learning
Organizational climate is operationalized as a shared consensual aspect of the
organization -- the shared perception among employees that the organization values
and supports continuous learning Describe how you would measure organizational
climate in this case Specify (a) the level (ie individual group organization) at
which the construct exists (b) the level at which you would measure the construct
and (c) the procedures that you would use to establish that measurement is aligned
with theory (ie the construct validity of the measure)
E) General (Measurement)
E1 Studies in organizational behavior research often rely on single-item measures of
key constructs The use of single-item measures has long been criticized based
on the premise that single-item measures are unreliable However Wanous
(Wanous amp Hudy 2001 Wanous amp Reichers 1996 Wanous Reichers amp Hudy
1997) has recently argued that single-item measures can exhibit adequate
reliability Wanous based this conclusion on a procedure for estimating the
reliability of single-item measures using the classic formula for correction for
attenuation Subsequent studies have yielded mixed results regarding the
conclusions of Wanous (eg Loo amp Kells 1998 Nagy 2002) and the veracity
of the perspective advocated by Wanous remains in question Summarize and
assess the arguments for and against the use of single-item measures and
evaluate the procedure and evidence offered by Wanous regarding the reliability
of single-item measures Based on your assessment and evaluation develop
recommendations regarding the use of single-item measures in organizational
behavior research

E2 Ipsative measures have become prevalent in organizational behavior research
Ipsative measures ask respondents to answer questions relative to one another
such that the scores for all questions sum to the same constant for all respondents
Examples of ipsative measures include rankings Q-sorts and the allocation of a
fixed number of points (eg 100) across a set of response options Ipsative
measures may be contrasted with absolute measures which ask respondents to
answer questions independently from one another Absolute measures are
exemplified by rating scales using an interval or ratio numeric response format
The relative merits of ipsative and absolute measures have been debated for
decades (eg Cornwell amp Dunlap 1994 Hicks 1970 Johnson Wood amp
Blinkhorn 1988 Saville amp Wilson 1991 1992) yet the fundamental issues
underlying this debate have not been adequately addressed in organizational
behavior research For example measures of organizational culture and values
are often ipsative and some researchers advocate these measures over absolute
measures (eg Meglino amp Ravlin 1987 OReilly Chatman amp Caldwell 1991
Ravlin amp Meglino 1987 see also Rokeach amp Ball-Rokeach 1989) Review the
relative merits of absolute and ipsative measures Based on your review which
form of measurement is most appropriate and why Do your conclusions depend
on the construct being measured If so what types of constructs are best suited to
ipsative measures and what types are best suited to absolute measures Next
apply your conclusions to the measurement of culture and values in
organizations What specific arguments have been advanced in favor of ipsative
measures of culture and values How sound are these arguments Should ipsative
measures be used in the study of organizational culture and values If not how
can absolute measures of culture and values be developed that address the
concerns voiced by advocates of ipsative measures Provide a specific example
of the type of measure you would propose

facets of a concept Although such measures are prevalent and in some cases are
advocated (eg Law et al 1998 1999) they can present a variety of conceptual
and methodological problems Describe the specific problems associated with
measures that use items representing different facets of a concept Compare these
problems with the purported advantages of such measures Conclude by

E5 Suppose Roberta Von Eisenbrick is a researcher interested in the consequences of
AFFECTIVE CONFLICT (AC) in decision-making teams She gets access to a
variety of outcomes assessment committees at each of 87 different schools in
the Dallas Independent School District and gains permission to tape-record two
of their meetings (one in February and one in March) Such committees have
been formed to develop quantitative ways to track pursuit of school goals and
provide accountability to local and state governments These are often divisive
teams with heated meetings because what gets assessed is what usually gets
rewarded After both of these meetings the committee members each
fill out a short questionnaire that contains 20 Likert-type items measuring how
much AC occurred (eg People in our group often get angry with each other)
The individual scores are summed across items then averaged across team
members to come up with a group-level AC score for each of the 87 2
meetings The same procedures are followed for a 5-item measure of Group
Cohesiveness (GC) which is predicted to be reduced by higher levels of AC
Roberta also listens to every tape and from her expert judgment she rates each
groups meetings on the same 20 items Those 20 ratings are summed for each of
the 87 2 meetings Now Roberta is interested in evaluating her measure She
wants it to have excellent psychometric properties including reliability and
construct validity

definition to the context given above

least three kinds of estimates and the sources of error each one assumes or is
estimating Pick one of those kinds of estimates and provide a rationale for using
it
c What is construct validity Discuss how the (un)reliability of the AC measure
could affect the conclusions one would draw from a study involving it and GC In
your discussion be sure to go over the connection between reliability and
validity and the connection between reliability and the probability of Type I or
Type II statistical errors

B2 In recent years (and in not so recent years for that matter) methodologists have
criticized the fact that psychologists rely heavily on significance testing What
are the essential elements of these critiques What are some remedies to the
problems engendered by significance testing and why have these remedies not
been widely adopted
B3 (a) There is a debate among the IndustrialOrganizational psychologists on
whether we should abandon significance testing and report confidence intervals
instead Please summarize arguments from both sides and state your position on
this issue

things that researchers have inappropriately sanctified the p lt 05 level of
significance Describe and critique the arguments for and against the use of
statistical significance testing in empirical research What information other than
significance levels can be used to interpret the meaning of empirical research

D) ModeratorsMediators
D1 Moderation and mediation provide different ways to model third variable effects
(a) Please define both of these terms (b) Sketch a conceptual model to show how
each relates to main effects (c) Using variables of your choice please write
hypotheses to reflect both (d) Explain how each is tested analytically
D2 Discuss moderators and mediators Provide an example of how (1) a moderating
variable influences the relationship between the independent and dependent
variable and how (2) a mediating variable influences the relationship between
the independent and dependent variable Describe how you would test for both
moderation and mediation using regression
D3 Many theories in organizational research predict that the effects of one variable
on another are moderated by a third variable Such moderator effects are
typically tested by entering the product of two variables as a predictor after
controlling for the two variables that constitute the product Several researchers
have pointed out that this product is often highly correlated with the squares of
the two constituent variables and have suggested that moderating effects may be
tested after controlling not only for the two constituent variables but also their
squares (eg Cortina 1993 Ganzach 1998 Lubinski amp Humphreys 1990
MacCallum amp Mar 1995) Discuss the strengths and weaknesses of this
approach as compared to methods that use only the product term and its
constituent variables Conclude with recommendations as to when and under
what conditions organizational researchers should test moderator effects with the
squares of the constituent variables in the equation

D4 Assume you are interested in studying relationships amongst three variables X
Y and Z Your first hypothesis posits Z as a mediator of the relationship between
X and Y Your second hypothesis posits Z as a moderator of the relationship
between X and Y Draw the figures depicting each of these hypothesized
relationships and describe (make sure to write regression equations) how you
would test each of these hypotheses
D5 The amount of time and effort that the average person pours into his or her job
has risen steadily over the last two decades such that the average person now is
working one more week per year than the average person in the mid 1970s This
steady increase has fueled research interest in the construct of Job Burnout (JB)
which is an emotional and physical exhaustion associated with ones work
Organizational Stress (OS) the perception of greater demands than available
resources in ones work environment is thought to be one of the chief
antecedents of JB However time spent under OS is thought to make its affects
on JB accumulate or worsen Work Role Withdrawal (WRW) the avoidance of
responsibilities or the deliberate reduction of inputs to ones job is believed to be
the chief consequence of JB
a Formally state these ideas as verbal hypotheses as equations and as a complex
directed graph (circle amp arrow diagram)
b Conceptually what is a mediator Define the term and identify the mediator in
your hypotheses in (a) What elements or steps in a study design (not statistics)
that would be helpful for detecting the mediating relationship that was proposed

subdomains of management Further demonstrate your understanding of
moderator variables by picking which variable in (a) is the moderator Show the
moderating relationship in an X-Y (or multi-layered) chart Again what elements
or steps in a study design (not statistics) would be helpful for detecting the
moderating effect implied above

F) Applied Data Analysis
16) Q Your departmental chair is considering a new textbook and has asked for your
recommendations You conduct a well-designed controlled study (details are unimportant) and discover students who use the new book perform 10 better on a standardized subject
matter exam than those using the old book (p = 027) Both books are readily availabe their prices are almost identical and both are equally acceptable to the instructors What is your recommendation to the chair
F1 Attached is the beginning of an article Your task is to write the results section by
1 making up and reporting plausible descriptive statistics that will help the
reader understand the results of the statistical tests you report and the nature of your
sample (Hint this can be presented in the form of a table)
2 describing and defending your choice of appropriate statistical tests of the
hypotheses and the steps that you would go through in carrying out these tests
3 making up and reporting results of these tests that are consistent with your
descriptive statistics and with any information in the rest of the article about the
results found (Hint this can be presented in the form of a table)
4 describing how well these results provide support for the hypotheses You
may want to note any relevant threats to validity here
Be sure to state any assumptions you make
F2 Assume that the Personnel Manager of a local firm Ms B dFlandres hired you to
analyze some data that her assistants had collected over the past several years The
data consist of (a) job performance ratings that were made in June of 1990 and (b)
scores on 25 predictor variables (eg measures of education job experience job
tenure job aptitude personality) that were measured when the individuals were hired
(between April 1987 and May 1988) She had data from only the 110 subjects (60
males and 50 females) who were hired during the period and were still employed by
the firm One objective of your analysis (analyses) is to determine how well the
performance criterion can be predicted by the predictors What strategy would you
use in analyzing the data Describeexplain (b) Is sample size an issue for your
analyses Explain If it is what will you do to deal with problems stemming from
sample size Assume that no additional data can be collected at this time (c) Some
preliminary analyses that you do reveal that five of the predictor variables correlate
(zero-order basis) about 75 with one another Will this influence the analyses that
you use Will it influence the validity of conclusions derived from your proposed
analyses (d) Ms dFlandres is interested in knowing if the predictor variables are
equally effective in predicting the job success of males and females What analysis
or analyses would you do to deal with this issue
F3 Assume that you have been provided with data on 12 conceptually distinct variables
that are moderately correlated with one another at the empirical level The data are
from students in four different college majors ie astronomy (A) biology (B)
criminology (C) and demography (D) The 12 measured variables fall into the
general categories of mental health (tension emotional withdrawal hallucinations
guilt feelings blunted affect and suspiciousness) and job satisfaction (work itself
supervision co-workers pay promotion prospects and working conditions) Your
task is to determine if the individuals in the four college majors differ from one
another on the 12 measured variables
(a) What statistical technique(s) would you use to test for group differences
Explain Be specific about the procedures(s) that you would use
(b) What statistical estimate would you use to estimate the extent to which the
groups differ from one another Be specific
F4 The following statistical table published in a recent issue of Work amp Occupations
was taken from an article discussing variables influencing resistance and citizenship
behaviors in the workplace Resistance behaviors include playing dumb withholding
effort work avoidance subverting particular managers and sabotage Citizenship
behaviors include cooperation engaging in peer training use of insider knowledge to
facilitate production commitment to organizational goals giving extra effort freely
Both measures are global constructs aggregated to the interval level and
standardized
The table reports the results of a series of ordinary least squares regression equations
with standardized coefficients Explain the meaning of the statistics presented What
do these statistics tell us generally about the relationship between resistance
behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows
Anomie Index -standardized interval level measure tapping multiple dimensions
The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)
F5 Researchers collected data from a sample of 350 companies on the following
variables
size (measured as number of employees)
Business Strategy (a nominal variable with 2 response options low-cost provider or
differentiator)
HR Strategy (a nominal variable with 2 response categories High commitment or
low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

as you see it within the time span of your career as an academic To do this use
examples of already written (or yet to be written) articles as models
J5 A frequent criticism of non-quantitative research summaries (literature reviews) is

affected the statistical outcomes of the studies included in the literature review Meta-
analysis however allows one to statistically examine such effects Assume you are
conducting a meta-analysis of the relationship between leader behaviors and group
productivity Briefly describe the steps you would take in conducting a meta-

model For each of those three statistical procedures describe and discuss the
following
a The type of data necessary for using the technique appropriately

assumptions usage and limitations
O3 How do exploratory and confirmatory factor analysis differ What are the
advantages and disadvantages of each
O4 Describe the differences between exploratory factor analysis (EFA) and
confirmatory factor analysis (CFA) When would you use one verses another
Are there ways to use EFA in a confirmatory way Can you use CFA in an
exploratory way Also describe the difference in principal components analysis
(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression
O6 The basic factor analysis model can be represented by the matrix algebraic
equation A B = C

information in each matrix and its purpose
(2) For what purpose do researchers use factor analysis Explain In the process
provide a very brief description of a study for which factor analysis would be a
useful data analytic technique
O7 Factor analysis is an important statistical technique in organizational research
Describe factor analysis as an analytical tool including the following issues
a the reasons for using factor analysis
b the type of data necessary for using the technique appropriately
c the type of quantitative output that results from applying the technique
d how a researcher would use the output in his or her research
e how confirmatory factor analysis is different from exploratory
f the important issues and problems in using the technique
P) Structural Equation Models
P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)
Please comment on these restrictions versus access argument Which side do you
take
What are the strengths of SEM Give some examples
What are the weaknesses of SEM Give some examples

outlets A group of 45 salespeople in one city were given two weeks of training
Measures of individual sales performance were taken once two months prior to the
program and once two months after Forty-five salespeople (who did not receive the
training) in a similar city had the same measures taken at approximately the same
points in time The training group increased their average weekly sales from $14000
to $16500 while the non-training group improved theirs from $13000 to $14500
The change for the training group is statistically significant the change for the non-
training group is not
How would the interpretation of these results in this quasi-experimental design
differ from a true experimental design What are the threats to internal validity in
the above study and how might they be operating (be specific) What additional
information and analyses would be useful in controlling for these threats
H3 An accounting firm is interested in determining if a re-training program will reduce
errors made by its audit teams A group of 45 auditors in the home office location
are given two weeks of re-training Measures of the frequency of detectable errors
are taken once two months prior to the program and once two months after Forty-
five auditors in similar office at a branch location have similar measures taken at
approximately the same points in time The training group reduced their average
number of errors per audit from 8 to 3 while the non-training group reduced theirs
from 11 to 9 The change for the training group is statistically significant the change
for the non-training group is not
How would the interpretation of these results in this quasi-experimental design
differ from a true experimental design What are the threats to internal validity in
the above study and how might they be operating (be specific) What additional
information and analyses would be useful in controlling for these threats
H4 Describe the main classes of threats to validity that are found in quasi-experimental
research designs
H5 Dr Delta an organizational development consultant was hired by a firm that has
600 pizza parlors nationwide to assist in implementing organizational changes that
he hopes will result in higher levels of job involvement At the outset of the study
subjects had jobs with very low levels of enrichment and were paid on an hourly
basis He designed an experiment in which stores were randomly assigned to one of
three treatment conditions Condition 1 subjects experienced job enrichment (JE)
and a change to performance-based pay (PBP) Condition 2 subjects experienced
only JE and Condition 3 subjects experienced only PBP The parlors were
sufficiently far apart from one another and communication among the parlors so
poor that subjects in any parlor were totally unaware of changes made in other
parlors At the end of 18 months he measured the job involvement levels of workers
and then tested for differences between the three conditions using a standard one-
way analysis of variance In view of Dr Deltas design answer the following
questions
How sound is Dr Deltas design Comment on the weaknesses of the design
I) Interrupted Time Series Design
I1 What threats to internal validity are and are not ruled out by an interrupted time series
design that includes the introduction of a treatment and its removal at a subsequent
time period List and explain In the process be certain that you provide a diagram
that illustrates such a design
J) Validity Some Questions are about the validity of a measure others about experimental validity)
10) Identify four threats to internal validity and briefly describe what they mean
J1 It was some time ago that the tripartite view of validity was abandoned in favor of a
unitarian view in which different evidentiary bases for validity might be put forward
Binning amp Barrett (1989) represent an attempt to place multiple evidentiary bases into a
single framework Cook amp Campbell (1979) describe four aspects of validity but they
arent really meant to represent evidentiary bases Adding to the confusion is the fact
that while Binning amp Barrett and Cook amp Campbell use some of the same terms these
two pairs of authors clearly mean different things by these terms and intend for them to
be used in different ways Your task is to 1) Describe the evidentiary bases discussed
by Binning amp Barrett 2) Describe the aspects of validity described by Cook amp
Campbell 3) Describe the similarities and differences between the two lists including
the different purposes served by the two lists and 4) Present a single framework that
incorporates both This last task is the most important of the four
J2 What are the types of validity How would each affect an empirical study IC
J3 Define both internal and external validity Which is more important (it is not okay to
say that they are equally important) Defend your reasoning
J4 Why might someone argue that the construct validity of a measure can never really be
established
J5 Describe each of the following forms of validity content convergent discriminant
criterion-related and construct How is each assessed How do they related to each
other Which is most important (Make sure you defend your answer)
J6 Define and explain 6 of the 8 types of validity listed below and describe the type(s) of
information each provides Choose one specific type of study as an example (eg
cross-sectional study experiment quasi-experiment simulation ethnography etc) and
compare and contrast the usefulness and importance of each type of validity for that
type of study
-- Concurrent validity
-- Construct validity
-- Content validity
-- Convergent validity
-- Discriminant validity
-- Statistical conclusion validity
-- Internal validity
-- External validity
J7 Designing empirical research has been called making a series of trade-offs
Unfortunately decisions that are made to increase one desired quality (like internal
validity) can also decrease another desired quality (like external validity) For each of
the issues below discuss the concerns involved (ie the trade-off) and identify the
qualities that are being increased or decreased
a laboratory vs field study
b using a 5-item measure vs a 1-item measure
c using a student sample vs a sample of full-time employees
d using a sample of employees from one company of 5000 vs 500 employees from
each of 10 companies
e collecting your data using one method vs collecting your data using multiple
methods
J8 There are four major types of validity in social science internal validity external
validity construct validity and statistical conclusion validity Please address the
following three issues concerning validity
a What is the meaning of the four major forms of validity (ie internal and external
validity construct validity statistical conclusion validity)
b Are there trade-offs that can or must be made among the four types of validity
d Describe how the concept of validity varies across the research traditions of
experimental vs observational research
IC
J9 The quality of research is often assessed by examining validity issues As you are
aware there are numerous typesforms of validity (eg internal and external validity
construct validity statistical conclusion validity) These types of validity address
different aspects of the research process For this question please address the following
issues
a What is the meaning of the four major forms of validity (ie internal and external
validity construct validity statistical conclusion validity)
b Should there be a priority among these forms of validity If yes why If no why not
c Does the concept of validity vary across research traditions (ie experimental vs
observational research) If yes why If no why not
J10 External validity has received considerable attention in the social and behavioral
sciences Some researchers argue we are too concerned with the external validity of our
findings while other researchers argue that we are too unconcerned with external
validity Several points of view have been developed to explain what is external
validity When answering this question please be sure to address at least the following
issues
a Compare and contrast alternative conceptualizations of external validity
b Some researchers have argued that the role of external validity is invariant across
research traditions (ie experimental vs observational research) Defend the
perspective that the role external validity is invariant across these two research
traditions In addition present the weaknesses of this perspective
J11 In designing a research study researchers must consider trade-offs between internal and
external validity Explain what is meant by internal validity and external validity What
is the nature of these trade-offs How would you evaluatedetermine which is more
important internal or external validity for a particular study Why is this such an
important issue in organizational studies
J12 A researcher conducted a quasi-experiment to test the effects of participative decision
making (PDM) on job attitudes of employees Employees from different departments in
a large organization were assigned to either a treatment group (PDM implemented) or a
control group (no PDM) Random assignment was not possible because of work
schedules coordination of tasks etc Thus the design can be considered an untreated
control group design with pretest and posttest and is represented as follows (where
O=observation X = treatment)
________________
O1 X O2
-------------------------
O1 O2
_________________
The results of the experiment are presented in the graph below [no graph provided]
The dependent variable is job satisfaction and is measured on a 100 point scale (with
100 being extremely satisfied) How amenable are these results to causal interpretation
What is (are) the major threat(s) to internal validity B if any B for this type of design
given these results What steps can be taken to assess the extent of this (these)
threat(s)
K) Data Collection Methods
14) Describe the various methods of data collection (eg survey interview observation etc)
available to a social scientist What are the advantages and disadvantages of each relative to
each other
K1 Within micro organizational research much criticism has been raised concerning
the reliance on self-report survey data What potential problems does self-report
survey research raise How big of a problem do you think this is
K2 There are a number of methods for collecting data (eg survey interview archival
etc) that are available to a social scientistorganizational researcher Discuss each in
terms of their strengths and weaknesses both on their own and in comparison to one
another
K3 Pick an important construct in your favorite area of management research for which
there is some controversy about how it should be measured or operationalized (eg
environmental munificence or growth need strength) Give the prevailing verbal
definition of the construct and analyze the measurement controversy from two
broad angles First discuss how the controversy may or may not stem from claims
about how one measure is better or worse than another because it (or the other) is an
(a) archival record (b) direct observation (c) social report or (d) self-report That is
what are the relative strengths and weaknesses of each of these types of
measurement for the construct youre discussing Second discuss the construct
validity of the most commonly used measure(s) of this construct To answer this
second part you need to discuss just what construct validity is and how it can or
cannot be demonstrated In the situation you describe what could be done to
demonstrate or improve the construct validity of existing measures
K4 Interviewing in some form has been the workhorse for data collection in a variety
of research traditions positivistquantitative ethnographic feministpost-modernist
and increasingly historical research While each tradition elicits information from
respondents the goals and processes involved in interviewing vary considerably
across research traditions Discuss the purposes of the interview the relationship
between data and theory the roles assumed by the interviewer and the respondent
and the relevant criteria for assessing the validity and reliability of the information
obtained In addition compare and contrast the use of the interview as a data
collection method in the positivistquantitative tradition with its use in one of the
alternative traditions
L) Common Method Variance
L1 Many of us have had concerns about the reviews of our survey research which
suggest that data analyses of surveys are biased because of common method
variance effects of individual differences such as negative mood negative
affectivity and social desirability and the reliability and validity of the constructs
we are attempting to measure Define how these problems affect a research issue in
organizational behavior and the steps that might be taken to minimize such potential
criticisms of papers based on analyses of self-reported data through survey
instruments
L2 In a series of papers by Spector (1994) Schmitt (1994) and Howard (1994)
published in the Journal of Organizational Behavior arguments were provided for
and against the use of self-report questionnaire measures One of the issues
discussed that could limit conclusions drawn from relationships observed using self-
report measures was method variance What is meant by method variance what are
its sources and what impact is it expected to have on research findings
M) Sampling
M1 The manufacturing census samples all plants of 250 employees or more For
plants of 5-249 employees it takes a size proportional sample Plants of 1-4
employees are not sampled What challenges does this sampling method provide
to researchers What could you do to account for these problems if you were
TH
studying organizational (not plant) growth
M2 New York State has approximately 250000 employees in over 70 state agencies
commissions and boards ranging in size from approximately 50 to over 5000
employees Assume that you wanted to draw a representative sample of 1000
employees Describe two ways that you could draw such a sample and briefly
describe the advantages and disadvantages of each of these sampling approaches
IC
M3 The director of a national non-profit agency with approximately 10000
employees located primarily in regional offices in each of the 50 states the
United States has approached you and asked you to develop a study
(organizational survey) of organizational culture within the agency The agency
is about to embark on a variety of change initiatives including developing team
structures and the study is meant to examine various elements of organizational
culture that are potential barriers to change The director has indicated that he
would like to have the data analyzed at both the individual and office level of
analysis Because of funding limitations the agency will only be able to send the
survey to 1000 employees The director has indicated that there are three ways
of sorting employees all employees listed alphabetically all employees listed
alphabetically by state and all employees listed alphabetically by region (there
are between five and ten regions per state) Given these three ways of sorting
employees describe at least three different sampling approaches and the
advantages and disadvantages of each
M4 In your role as Teacher of Organizational Studies you are asked to prepare a
tutorial for beginning doctoral students on sampling design Assume that this
tutorial is part of a basic class in research design and that students in this class
have had a basic statistics course up to and including multiple regression Your
tutorial should focus on briefly defining and explaining the differences between
probability and non-probability samples You should make sure to present and
describe several types of probability samples (eg random systematic
stratified etc) and non-probability samples (eg convenience snow-ball quota
etc) and discuss general principles for when to use a probability vs a non-
probability sampling design For each sampling design you should also provide
at least one clear example of a situation where this type of sampling design is
appropriate
N) Cross-Cultural Research
N1 Discuss the problems in conducting cross-culturalnational comparison in terms
of (1) conceptualization and (2) research design and data collection
Define the three levels of measurement invariance How would the problems that
you have identified in part (a) affect measurement invariance How would you
examine measurement invariance by confirmatory factor analysis
TH
N2 Explain why using national boundaries as independent variable in cross-cultural
studies may not be appropriate in terms of theory and research methods What
alternative ways would you recommend
IC
O) General
O1 In your readings research has been described as choices among conflicting goals
(desiderata) For instance when choosing among research strategies a researcher
must choose among the desiderata of precision realism and generalizability The
trade-offs among desiderata occur for all aspects of research that is for the selection
of theories the treatment of independent variables research strategies the selection
of the problem to study rules of evidence for determining the meaningfulness of a
research finding and even the frameworks that describe the research process
Discuss what you see as the major trade-offs for each of the following aspects of
research That is discuss what you see as the major strengths and weaknesses
(advantages and disadvantages) of each aspect
a The trade-offs between internal and external validity
b The manipulation of the independent variable vs the observation of the
independent variable
c Basic vs applied research
3 DESIGNING A RESEARCH STUDY
A) General (Research Design)
3) Why is control so important in research design What are the different ways it can be
achieved (give a brief description of each control method) What are advantages and
disadvantages of each
A1 It has become almost a truism to note that the choice of methods influences theory
and questions data and conclusions (the causal direction might also be reversed)
Briefly discuss how the methods used have influenced research in any two of the
following areas leadership power and politics organization culture organization
justice Compare and contrast as possible Suggest some potentially fruitful
methodological directions for future work in these same topical areas and dont be
shy about reflecting on broader issues of how the field of organizational behavior
constructs its realities Lastly tie your discussion and reflections back to your own
future as a researcher what lessons or guidance do you derive from your
understanding of these issues
A2 Characterize as fully as possible what you see to be the methodological approach or
approaches in strategic management research Is there a dominant method or a wide
variety Discuss the reasons for the situation What are the advantages benefits etc
of the approach(es) in use What assumptions (ontological epistemological
ideological) do they embody Are current efforts ideal or at least adequate Are
there other approaches that could be useful If so how might researchers be
encouraged to use these as well If you see no advantage to more variety in
methodological approach support that point of view
A3 Describe a research question or area of interest to you and why you think it is not
only of interest but significance Using your understanding of research methodology
describe two ways of pursing the question that are as divergent on as many
dimensions as you can imagine Describe the advantages and disadvantages of each
approach How strong a link or fit is there between a research question and a
method
A4 In his 1957 article entitled The two disciplines of scientific psychology Cronbach
discussed the assumptions goals and methods used in experimental methods and
correlational methods in psychology
a According to Cronbach what is the main difference between the two disciplines
b Discuss the strength and weaknesses of each discipline
c What if anything could be done to improve the situation
B) Designing a Research Study
B1 Cook and Campbell describe the experiment as the research design with the
greatest methodological rigor However given the constraints present in most
organizations I-O Psychologists cannot often conduct experiments in applied
settings and must settle for techniques with less control than experiments
Describe a study to investigate the relationship between participation in a
supervisor training program and work performance which could realistically be
conducted in an organization If an experiment is not possible describe how you
would go about maximizing your ability to draw valid conclusions from your
design
B2 The XYZ Co has recently developed a sexual harassment web-based training
program The developers claim the program will cut training time and costs and
will be as effective or more effective than classroom-based sessions They
believe that this will be due to the increased availability of the program and the
ability for participants to review program material on demand Before the XYZ
Co developers launch this product they want you to determine if their claims
have merit Explain how you would design a study for this purpose
B3 Research suggests that demographic diversity improves group creativity but
reduces group efficiency Some argue that demographic diversity is just a proxy
for value and experience diversity and that demographic diversity on its own is
meaningless Design a test to settle this argument
TH
B4 E-mail has become a common form of communication in organizations and is
used for both formal and informal communication Because it has become so
IC
popular some people complain that the frequent use of e-mail leads to
miscommunication because they receive communications in e-mail that should
be accomplished through face-to-face or telephone conversations where there is
an opportunity for interaction You are interested in looking at this
phenomenon You are most interested in describing how e-mail is used for both
formal and informal communication and in examining the effect of the e-mail
use on organizational communication effectiveness Design empirical research
to address those issues
Describe your study in detail thoroughly explaining the research design
sampling plan data collection procedures ethical issues and proposed data
analysis for your research design Be sure to discuss the internal and external
validity of your research Which validity threats are ruled out and which
remain
REMEMBER Be thorough Your research design should demonstrate that you
are a competent researcher who is knowledgeable about the proposed research
methodology or methodologies Therefore be sure that you carefully describe
and give technical explanations for each component of your research
B5 Choose a specific situation involving employee selection eg artists for an
advertising agency (a) What strategy would you use in selecting the selection
measures (b) How would you combine the measures eg which measures
would you combine in a compensatory manner and which is a noncompensatory
manner (c) How would you assume test fairness defining various measures of
the term (d) How would you make final selections (e) How would you
validate your procedure (f) What considerations would enter in if your
company were too small to provide validation data (g) What difference would
it make if you were developing a procedure for deciding whether trainees
should be promoted as opposed to making new hires Please note--emphasize
but do not limit yourself to statistical issues
B6 There is evidence in the marketing literature of a non-monotonic relationship
between the expectations that customers have for retail service and their
eventual level of satisfaction with that service That is as a customers
expectations for service increase so does their eventual service satisfaction --
up to a point After that point the greater the expectations the lower the
eventual satisfaction Develop a hypothesis that includes a moderator variable
that might account for this evidence Give some reasonable rationale for it State
your hypothesis verbally as an equation as a directed graph (circle amp arrow
diagram) and as an X-Y function chart Discuss how it would or would not be
possible or useful to test your hypothesis via a laboratory experiment In your
discussion cover how and why a researcher could (not) manipulate the
independent constructs involved (mode X) whether or not random assignment
to conditions (mode R) is possible (including how may conditions would be
necessary) which alternative constructs could or could not be controlled (mode
K) and which constructs should be measured (mode Y)
B7 Assume you are the chairperson of a committee that must evaluate
undergraduate programs at your university Your task as chairperson is to
devise an approach (a design a research strategy a set of measures) that will
allow you to evaluate undergraduate programs Make sure that your approach
can be used in the future and at other comparable universities When developing
your plan be sure to address at least the following issues
a the type of design you would select Compare and contrast the selected design
with another possible design
b the type of research strategy you would select Compare and contrast with
another possible strategies
c discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
B8 Assume you are an organizational research design expert assigned to the
Strategic Planning Department of a large multi-national manufacturing firm
The Department has developed a new PC-based software package called
STRATPACK The software (and a one-week training course to learn how to
use it) is intended to improve the long-range planning ability of middle and
upper-level managers
Your job as research design expert is to devise research (a design a research
strategy a set of measures) that will allow you to evaluate the effectiveness of
the STRATPACK program Describe a research design for evaluating the
program Make sure that your research approach can be used in the future and at
all sites in the company When developing your plan be sure to address at least
the following issues
a discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
b the type of design you would select (eg a design where you manipulate the
independent variable versus observe the independent variable) Compare and
contrast the selected design with another possible design
c how your design deals with the major forms of validity Be sure to examine at
least internal external and construct validity
B9 Assume you are a consultant hired to evaluate the effectiveness of an industrial
safety program undertaken by a large manufacturing organization The safety
program is a behavioral one that provides rewards such as monetary bonuses or
extra paid vacation days for safety behaviors in terms of accident-free days
weeks etc Your task is to devise an approach (a research strategy a design a
set of measures and a general analysis strategy) that will allow you to evaluate
the safety program Because of the potential for the influence of many
extraneous variables on any safety program it is difficult to design research a
single cross-sectional study than can evaluate the impact of a single safety
program How would you design a study to evaluate the impact of the safety
program When developing your plan be sure to address at least the following
issues
a the type of research strategy you would select Compare and contrast with
another possible strategies
b the type of design you would select Compare and contrast the selected design
with another possible design
c discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
B10 One of the most important areas of research is forecasting of human resources
needs based on strategic positions of organizations For example NY State must
carefully forecast its human resources needs as it proceeds with significant lay-
offs of state employees Future human resources needs are generally evaluated
by either statistical ie regression or simulation or clinical judgment i e
supervisors judgments methods
a Design a single study that addresses the empirical question of whether
statistical or judgmental methods are better for forecasting human resources
needs You may discuss a program of research but please be quite specific in
your description of the first study
b What are the critical methodological issues in doing this kind of research
c What are the critical applied (or practical) issues in doing this research
d Are the issues in b and c related
B11 In the past decade computinginformation technology has changed many
aspects of organizational life For example the technology can make increased
decentralization possible by improving communication between central offices
and field offices Computer networks and word processors can enhance group
empowerment by making it possible for team members to create and edit
written group products quickly even if the individuals are at different locations
Some have argued that computinginformation technology will foster the
paperless productive office nevertheless others argue that the technology only
increases paper and reduces office productivity You are applying to the
National Science Foundation for a grant to conduct research that examines the
impact of computing information technology on organizational decision
processes The NSF application procedure imposes five basic requirements that
your research design must fulfill in order to receive funding Note A very
significant factor affecting NSF grant decisions is a clear demonstration that the
researcher is knowledgeable about the research methodology used Write your
response to each of the following five grant requirements Be sure not only to
respond to the requirement but also to demonstrate your research
competence
1You must design a study that uses two different methods
(interviewobservation survey experiment or quasi-experiment) Describe your
two methods in detail and provide a rationale for the key elements (eg
sampling data collection proposed analysis) of your methods Be sure to
discuss and evaluate the internal and external validity of both methods
2 As part of your research design you must select a conceptual (latent) variable
central to your proposal (use centralization of decision making as your
variable) and describe how you will develop your own measure (You may not
simply use off the shelf instruments)
3 You must describe how you will test for the reliability of the measure
(centralization of decision making) you developed in step 2 The NSF insists
that you describe how you will evaluate both the temporal stability and the
internal consistency of your measure Be sure to discuss what temporal stability
and internal reliability mean and how they are related
4You must describe how you will assess the validity of the measure
(centralization of decision making) you developed in step 2
5 NSF requires a brief statement and defense of the philosophy of science
underlying your research Discuss your position and show how your research
design is consistent with your philosophy
B12 Many organizations in the United States economy have installed some form of
Empowered Teams as an alternative or supplement to traditional bureaucratic
structure Preliminary evidence of the effectiveness of empowered teams
however is mixed--some organizations have claimed success and others have
reported failures The evidence however is predominantly anecdotal--written
for trade magazines by the organizations themselves There are few rigorous
empirical studies assessing the effectiveness of empowered or self-managed
teams You are applying to the United States Department of Labor (USDOL) for
a grant to conduct research that examines the effectiveness of empowered
teams The application procedure of the USDOL imposes three requirements
that your research design must fulfill in order to receive funding Write your
response to each of the three grant requirements The importance of each section
is implied by the evaluation points allocated by the USDOL to each of the three
requirements given in parentheses
1 (50 points) Your study design for assessing Empowered Team effectiveness
must use two different methods (interview observation archival analysis
survey simulation experiment or quasi-experiment) Describe in detail and
thoroughly explain the sampling plan instrumentation data collection
procedures and proposed data analyses for both methods Be sure to discuss the
internal and external validity of both methods and how the two methods
complement one another
2 (30 points) As part of your research design you must select one conceptual
(latent) variable central to your proposal and describe how you will develop
your own operationalization of the measure (You may not simply use off the
shelf instruments) Use the concept of group morale to demonstrate your
operationalization methodology Be sure to explain very explicitly to the
USDOL how you will assess the validity and reliability of the group morale
measure you are developing
3 (20 points) The USDOL traditionally has funded research conducted only
within the general paradigm of logical positivism but now is more open to other
research paradigms as well Your grant proposal must provide a statement and
defense of the explicit philosophy of science underlying your research Describe
your philosophy of science and show how your research design is consistent
with your philosophy
REMEMBER Be thorough You not only must design effective research but
you also must demonstrate to the USDOL that you are a competent researcher
It is absolutely vital to the USDOL that the principal researcher is
knowledgeable about the proposed research methodologies Therefore be sure
that you always carefully describe and give technical explanations for each
component of your research design and explain all technical terms (eg
Cronbach alpha KR-20 Likert scale)
B13 Assume that you are working as part of a research team that is responding to a
RFP (Request for Proposals) from a funding agency for research on work
socialization and newcomer adjustment The RFP calls for rigorous field
research that tests the effectiveness of theory-based interventions aimed at
facilitating the adjustment of new organizational members to complex andor
stressful work conditions The major goal of your teams research is to test the
effectiveness of a self-regulation intervention which trains newcomers to
identify and use relevant social information and cues to regulate work behavior
Your group hypothesizes that self-regulation training will be more effective
than other common treatments or interventions (eg realistic job previews
institutionalized socialization tactics)
You have been included in the team because of your methodological expertise
Your role is to design a rigorous field experiment or quasi-experiment to test he
effectiveness of the self-regulation training program REMEMBER THE
MAJOR CRITERION FOR FUNDING IS THE RIGOR OF THE RESEARCH
DESIGN Design a field study to include in the grant proposal Your proposal
should contain the following two sections
1 Study Design Construct and describe in detail an experimental or quasi-
experimental design to test the effectiveness of your intervention Describe in
detail the experimental groups (including how they will be constructed) the
research setting the sampling plan for study participants the treatment
manipulation and the data collection procedures Also indicate any control or
nuisance variables that may be measured
After describing the procedures write a justification of the design What threats
to validity does it rule out or limit and what threats to validity remain
II Measurement Describe the steps you would take to achieve valid and
reliable measure of the latent (conceptual) variable worker adjustment Your
team feels that as part of the proposal you must develop an original
operationalization of adjustment (thus you cannot simply use existing off the
shelf measures) Indicate in adequate detail how you would operationalize the
measure and indicate how you would demonstrate reliability and validity
B14 In describing their notion of the collective mind Karl E Weick and Karlene H
Roberts note Our focus is at once on individuals and the collective since only
individuals can contribute to a collective mind but a collective mind is distinct
from an individual because it inheres in the pattern of interrelated activities
among many people (p 360) Collective mind is not indexed by within-group
similarity of attitudes ideas or activities A collective mind is one in which
many people or many groups integrate their different attitudes ideas and
activities heedfully As Weick and Roberts note People act heedfully when
they act more or less carefully critically consistently purposefully attentively
studiously vigilantly conscientiously pertinaciously (p 361)
The idea of the collective mind as heedful interrelating is developed in the
following excerpt When people make efforts to interrelate these efforts can
range from heedful to heedless The more heed reflected in a pattern of
interrelations the more developed the collective mind and the greater the
capability to comprehend unexpected events that evolve rapidly in unexpected
ways When we say that a collective mind comprehends unexpected events we
mean that heedful interrelating connects sufficient know-how to meet situational
demands For organizations concerned with reliability those developments
often consist of unexpected non-sequential interaction (p366)
An example of heedful interrelating occurs as a pilot lands herhis aircraft on the
deck of an aircraft carrier The pilot does not actually land She is recovered
A recovery is an interrelated set of activities among air traffic controllers
landing signal officers the control tower navigators deck hands the helmsman
driving the ship etc These activities can be interrelated more or less heedfully
depending on the care with which the different units contribute represent the
situation and subordinate their activities to the single purpose of successful
recovery (p 363)
You are to design a two-part study
Part I You are to design a measurement study which assesses heedful
interrelating (ie collective mind) with a quantitative measure in a replication
of an aircraft carrier flight deck or other situation of your choosing Describe
your research strategies including operationalization of the variable selection of
the sample subjects data collection data analysis and so on for the purpose of
developing a measure of heedful interrelating
Part II Using the measurement tool developed in Part I and any other tools as
needed describe how you would design a study which would compare heedful
interrelating across organizations Choose at least one macro-organizational
variable (eg technology environment) as your basis of comparison Here you
must describe how you would make your selection of organizations to be
compared your data collection procedure data analysis and so on
B15 Many organizations in the United States have installed cross-functional teams to
counteract the silo mentality of traditional bureaucratic structure Preliminary
evidence of the effectiveness of cross-functional teams however is mixed --
some organizations have claimed success and others have reported failures The
evidence moreover is predominantly anecdotal--written for trade magazines by
the organizations themselves Since there have been few rigorous empirical

5 MEASUREMENT
A) Measurement Terms
A1 There are four levels of measurement rigor in management research Discuss each
one What properties do measurements at each level have (ie how much
information do the numbers from each level of measurement convey) How can the
numbers be changed (transformed) and still retain the properties of their
measurement level Pick one construct from a favorite research domain and give an
example of an operationalization of that construct at each of the four levels of
measurement rigor (provide arguments about why you think those examples reflect
each level) Lastly treat each examplelevel as a dependent variable in some
statistical analysis Given an example of a statistical technique appropriate for
analyzing data at that level of measurement rigor
A2 Define (and discuss important features or issues concerning) the following
constructs measurement (Define any six terms)
1 Construct validity 6 Item analysis
2 Likert scaling 7 Semantic differential
3 Cronbachs alpha 8 True score

estate agents self-assessment of performance Since there is no existing
measurement available you have to develop the instrument by yourself
Describe how you would develop the measurement assuming that you have no
idea of how many dimension the construct has
b) Suppose you have developed an instrument consists of 20 questions
measuring 4 dimensions (5 items per dimension) from (a) You collected data
from another 300 real estate agents to validate your instrument Explain how
TH
you would use structural equations model (SEM) to examine the reliability and
validity of the instrument What are other concerns about reliability and validity
that are not addressed by this approach
B2 The research and business world have been fascinated with the concept of
organizational culture However operationalizing this construct has been a
difficult task Discuss the ways in which the construct has been operationalized
(eg technique static v dynamic sample selection generalizability) Critically
analyze each of these methodologies Then choose a methodology you would
use to examine organizational culture and defend your choice Describe how
you would study culture and what more would be known about culture as a
result of your study
B3 Suppose you are setting out to develop a new measure of a construct You want
this measure to be used in survey research and you want to establish its validity
and reliability Your goal is to have at the end of the process a measure that is
defensible and likely to be widely accepted by other researchers studying that
construct What steps would you take to conduct such a program of research
For each step explain the purpose of that step explain why that step is
important explain what methods and statistical procedures you would employ at
each step and explain what evidence you would hope to gather at each step

relevant variable from your field) Detail the major concerns that need to be
addressed and the steps that need to be taken in working toward validating this
new measure
B5 Assume that you recently read an article on workplace violence which you
found very interesting The authors argued that one of the predictors of
workplace violence was a construct called propensity to be violent and used a
one-item measure as follows How likely are you to become violent when
provoked You had serious doubts about the authors measure and decided to
develop your own
(a) How would you go about developing items to measure propensity to be
violent
(b) How would you determine whether the instrument was reliable
How would you determine whether the instrument was valid
B6 A concern in organizations is retirement of baby boomers within the next 5 -
10 years This concern is focused on the loss of older employees with skills
critical to the core business functions of organizations In order to continue to
have employees with those critical skills it seems necessary to retrain some
older workers However past practice in most organizations has been not to
retrain older workers for a variety of reasons mostly financial A researcher
working for the Human Resources Department of a large corporation - 13500
employees in 12 different plant locations - hypothesizes that the major reason
for not retraining older workers is ingrained in the culture of the corporation
IC
The researcher feels that older workers are not as highly valued as younger
workers in terms of their potential usefulness after retraining The researcher
searched the literature but found nothing in the existing literature to measure
the cultural value construct What should the researcher do to establish a reliable
and valid self-administered paper and pencil measure of this construct namely
the value of retraining older workers

of the concept of technological complexity What standards would you use to
determine if your operationalization is valid
B8 Organizational researchers have several strategies available to them for
gathering information (eg self-report measures archival measures direct
observation and trace measures) Assume that you are going to conduct
empirical research to assess the role that the structure of the organization plays
in determining the level of organizational effectiveness Briefly review the
strengths and weaknesses of the basic strategies (that is self-report measures
archival measures direct observation and trace measures) for measuring
organizational effectiveness Next describe and justify the steps you would
take to develop an operationalization of the concept of organizational
effectiveness What standards and procedures would you use to determine if
your operationalization is valid
B9 One of the most important topics of recent research has been stress in the work
place One of the most important problems with understanding this literature is
the varying definitions and measurement of this construct Suppose you had
decided to investigate the relationship between stress at the work place and dual
career family happiness

your meaning of validity and reliability It is important that your measure have
all the necessary psychometric characteristics so that other scientist can trust the
results of your research

measure of stress at work with other measures of this construct How would you
do that

impact of interpersonal trust on organizational decision making Describe and
justify the steps you might follow to develop an operationalization of the
interpersonal trust concept

Further assume that you have used previous literature and your own conceptual
development to delineate 2 dimensions of X specifically XF1 and XF2
Describe the steps you would go through in developing testing and evaluating
this new scale With regard to testing and evaluating be sure to consider the
role of factor analysis (both exploratory and confirmatory) and item analysis
Also you will want to make sure that your new multidimensional scale shows
evidence of validity (several kinds) and reliability so be sure to examine these
issues and explain how specific information gathered from the above testing
contributes to these concerns

measure
C9 Define reliability Name some methods of calculating reliability How well do
these methods map up with the definition of reliability What is the impact of the
number of test items and sample size on Chronbachs alpha and why would this
effect occur or not occur (Note Do NOT discuss inter-rater reliability)
C10 Schmidt and Hunter (1996) described several types of measures typically used in
organizational research and identified the type(s) of measurement error affecting
each of them in various situations For each measure below indicate the types of
error and sources of error that are most likely to affect it Then indicate what
could be done to reduce errors of measurement andor what can be done to
control for errors statistically

worker)
d Aptitude tests taken as part of the hiring process
C11 Suppose you had conducted research on the relationship between organizational
commitment and rigidity of organizational structure in 200 firms Your measure
of rigidity was based on number of organizational authority levels and the degree
to which written organizational rules existed and defined role behaviors for
employees Thus an organization with a large number of organizational levels
and specific written policies defining appropriate role behaviors for employees
would score high on rigidity of organizational structure After analyzing your
data you find that there is a statistically significant negative correlation between
commitment and rigidity which is consistent with your hypothesis However the
reliabilities for your two measures are
(1) commitment = 23 (2) rigidity = 83
How should you interpret your results What could you do to fix this situation
Describe the specific steps (in order) you would follow to develop a more
reliable measure of commitment

interrater agreement and reliability methods be used (Rwg Kappa and Weighted
Kappa percent agreement average pairwise correlation ANOVA methods
(interclass correlation coefficient WABA)) What are the advantages and
disadvantages of each of the methods

data
(e) Provide some ideas for avoiding the need to aggregate in group-level research

research literature This type of research raises many issues and presents many
challenges in terms of designing the research measuring variables and collecting
and analyzing the data Assume that you are interested in aggregating data (eg
from the individual to the group or from the firm to the industry) for one or more
variables What are the major issues you will need to deal with
D3 A researcher wants to measure organizational climate for continuous learning
Organizational climate is operationalized as a shared consensual aspect of the
organization -- the shared perception among employees that the organization values
and supports continuous learning Describe how you would measure organizational
climate in this case Specify (a) the level (ie individual group organization) at
which the construct exists (b) the level at which you would measure the construct
and (c) the procedures that you would use to establish that measurement is aligned
with theory (ie the construct validity of the measure)
E) General (Measurement)
E1 Studies in organizational behavior research often rely on single-item measures of
key constructs The use of single-item measures has long been criticized based
on the premise that single-item measures are unreliable However Wanous
(Wanous amp Hudy 2001 Wanous amp Reichers 1996 Wanous Reichers amp Hudy
1997) has recently argued that single-item measures can exhibit adequate
reliability Wanous based this conclusion on a procedure for estimating the
reliability of single-item measures using the classic formula for correction for
attenuation Subsequent studies have yielded mixed results regarding the
conclusions of Wanous (eg Loo amp Kells 1998 Nagy 2002) and the veracity
of the perspective advocated by Wanous remains in question Summarize and
assess the arguments for and against the use of single-item measures and
evaluate the procedure and evidence offered by Wanous regarding the reliability
of single-item measures Based on your assessment and evaluation develop
recommendations regarding the use of single-item measures in organizational
behavior research

E2 Ipsative measures have become prevalent in organizational behavior research
Ipsative measures ask respondents to answer questions relative to one another
such that the scores for all questions sum to the same constant for all respondents
Examples of ipsative measures include rankings Q-sorts and the allocation of a
fixed number of points (eg 100) across a set of response options Ipsative
measures may be contrasted with absolute measures which ask respondents to
answer questions independently from one another Absolute measures are
exemplified by rating scales using an interval or ratio numeric response format
The relative merits of ipsative and absolute measures have been debated for
decades (eg Cornwell amp Dunlap 1994 Hicks 1970 Johnson Wood amp
Blinkhorn 1988 Saville amp Wilson 1991 1992) yet the fundamental issues
underlying this debate have not been adequately addressed in organizational
behavior research For example measures of organizational culture and values
are often ipsative and some researchers advocate these measures over absolute
measures (eg Meglino amp Ravlin 1987 OReilly Chatman amp Caldwell 1991
Ravlin amp Meglino 1987 see also Rokeach amp Ball-Rokeach 1989) Review the
relative merits of absolute and ipsative measures Based on your review which
form of measurement is most appropriate and why Do your conclusions depend
on the construct being measured If so what types of constructs are best suited to
ipsative measures and what types are best suited to absolute measures Next
apply your conclusions to the measurement of culture and values in
organizations What specific arguments have been advanced in favor of ipsative
measures of culture and values How sound are these arguments Should ipsative
measures be used in the study of organizational culture and values If not how
can absolute measures of culture and values be developed that address the
concerns voiced by advocates of ipsative measures Provide a specific example
of the type of measure you would propose

facets of a concept Although such measures are prevalent and in some cases are
advocated (eg Law et al 1998 1999) they can present a variety of conceptual
and methodological problems Describe the specific problems associated with
measures that use items representing different facets of a concept Compare these
problems with the purported advantages of such measures Conclude by

E5 Suppose Roberta Von Eisenbrick is a researcher interested in the consequences of
AFFECTIVE CONFLICT (AC) in decision-making teams She gets access to a
variety of outcomes assessment committees at each of 87 different schools in
the Dallas Independent School District and gains permission to tape-record two
of their meetings (one in February and one in March) Such committees have
been formed to develop quantitative ways to track pursuit of school goals and
provide accountability to local and state governments These are often divisive
teams with heated meetings because what gets assessed is what usually gets
rewarded After both of these meetings the committee members each
fill out a short questionnaire that contains 20 Likert-type items measuring how
much AC occurred (eg People in our group often get angry with each other)
The individual scores are summed across items then averaged across team
members to come up with a group-level AC score for each of the 87 2
meetings The same procedures are followed for a 5-item measure of Group
Cohesiveness (GC) which is predicted to be reduced by higher levels of AC
Roberta also listens to every tape and from her expert judgment she rates each
groups meetings on the same 20 items Those 20 ratings are summed for each of
the 87 2 meetings Now Roberta is interested in evaluating her measure She
wants it to have excellent psychometric properties including reliability and
construct validity

B2 In recent years (and in not so recent years for that matter) methodologists have
criticized the fact that psychologists rely heavily on significance testing What
are the essential elements of these critiques What are some remedies to the
problems engendered by significance testing and why have these remedies not
been widely adopted

whether we should abandon significance testing and report confidence intervals
instead Please summarize arguments from both sides and state your position on

(a) Please define both of these terms (b) Sketch a conceptual model to show how
each relates to main effects (c) Using variables of your choice please write
hypotheses to reflect both (d) Explain how each is tested analytically
D2 Discuss moderators and mediators Provide an example of how (1) a moderating
variable influences the relationship between the independent and dependent
variable and how (2) a mediating variable influences the relationship between
the independent and dependent variable Describe how you would test for both
moderation and mediation using regression
D3 Many theories in organizational research predict that the effects of one variable
on another are moderated by a third variable Such moderator effects are
typically tested by entering the product of two variables as a predictor after
controlling for the two variables that constitute the product Several researchers
have pointed out that this product is often highly correlated with the squares of
the two constituent variables and have suggested that moderating effects may be
tested after controlling not only for the two constituent variables but also their
squares (eg Cortina 1993 Ganzach 1998 Lubinski amp Humphreys 1990
MacCallum amp Mar 1995) Discuss the strengths and weaknesses of this
approach as compared to methods that use only the product term and its
constituent variables Conclude with recommendations as to when and under
what conditions organizational researchers should test moderator effects with the
squares of the constituent variables in the equation

D4 Assume you are interested in studying relationships amongst three variables X
Y and Z Your first hypothesis posits Z as a mediator of the relationship between
X and Y Your second hypothesis posits Z as a moderator of the relationship
between X and Y Draw the figures depicting each of these hypothesized
relationships and describe (make sure to write regression equations) how you
would test each of these hypotheses
D5 The amount of time and effort that the average person pours into his or her job
has risen steadily over the last two decades such that the average person now is
working one more week per year than the average person in the mid 1970s This
steady increase has fueled research interest in the construct of Job Burnout (JB)
which is an emotional and physical exhaustion associated with ones work
Organizational Stress (OS) the perception of greater demands than available
resources in ones work environment is thought to be one of the chief
antecedents of JB However time spent under OS is thought to make its affects
on JB accumulate or worsen Work Role Withdrawal (WRW) the avoidance of
responsibilities or the deliberate reduction of inputs to ones job is believed to be
the chief consequence of JB

E) Multiple Comparisons
E1 In your role as professional colleague you are called upon to advise another doctoral
student about the appropriate use of multiple comparisons and post hoc tests in
analysis of variance Your student colleague already has been introduced to ANOVA
and multiple regression Specifically you are to write out a description of how to test
for differences among the different levels or cells of a categorical variable In your
description you should discuss among other things
a the statistical and philosophical issues raised by post hoc analysis and data
snooping
b the different multiple comparison methods commonly used by researchers to test
for differences among cell means and
c the advantages and disadvantages of each method
Note Your written description will be evaluated based on your demonstrated
competence with the statistical method not on the pedagogy of your explanation
F) Applied Data Analysis
16) Q Your departmental chair is considering a new textbook and has asked for your
recommendations You conduct a well-designed controlled study (details are unimportant) and discover students who use the new book perform 10 better on a standardized subject
matter exam than those using the old book (p = 027) Both books are readily availabe their prices are almost identical and both are equally acceptable to the instructors What is your recommendation to the chair
F1 Attached is the beginning of an article Your task is to write the results section by
1 making up and reporting plausible descriptive statistics that will help the
reader understand the results of the statistical tests you report and the nature of your
sample (Hint this can be presented in the form of a table)
2 describing and defending your choice of appropriate statistical tests of the
hypotheses and the steps that you would go through in carrying out these tests
3 making up and reporting results of these tests that are consistent with your
descriptive statistics and with any information in the rest of the article about the
results found (Hint this can be presented in the form of a table)
4 describing how well these results provide support for the hypotheses You
may want to note any relevant threats to validity here
Be sure to state any assumptions you make
F2 Assume that the Personnel Manager of a local firm Ms B dFlandres hired you to
analyze some data that her assistants had collected over the past several years The
data consist of (a) job performance ratings that were made in June of 1990 and (b)
scores on 25 predictor variables (eg measures of education job experience job
tenure job aptitude personality) that were measured when the individuals were hired
(between April 1987 and May 1988) She had data from only the 110 subjects (60
males and 50 females) who were hired during the period and were still employed by
the firm One objective of your analysis (analyses) is to determine how well the
performance criterion can be predicted by the predictors What strategy would you
use in analyzing the data Describeexplain (b) Is sample size an issue for your
analyses Explain If it is what will you do to deal with problems stemming from
sample size Assume that no additional data can be collected at this time (c) Some
preliminary analyses that you do reveal that five of the predictor variables correlate
(zero-order basis) about 75 with one another Will this influence the analyses that
you use Will it influence the validity of conclusions derived from your proposed
analyses (d) Ms dFlandres is interested in knowing if the predictor variables are
equally effective in predicting the job success of males and females What analysis
or analyses would you do to deal with this issue
F3 Assume that you have been provided with data on 12 conceptually distinct variables
that are moderately correlated with one another at the empirical level The data are
from students in four different college majors ie astronomy (A) biology (B)
criminology (C) and demography (D) The 12 measured variables fall into the
general categories of mental health (tension emotional withdrawal hallucinations
guilt feelings blunted affect and suspiciousness) and job satisfaction (work itself
supervision co-workers pay promotion prospects and working conditions) Your
task is to determine if the individuals in the four college majors differ from one
another on the 12 measured variables
(a) What statistical technique(s) would you use to test for group differences
Explain Be specific about the procedures(s) that you would use
(b) What statistical estimate would you use to estimate the extent to which the
groups differ from one another Be specific
F4 The following statistical table published in a recent issue of Work amp Occupations
was taken from an article discussing variables influencing resistance and citizenship
behaviors in the workplace Resistance behaviors include playing dumb withholding
effort work avoidance subverting particular managers and sabotage Citizenship
behaviors include cooperation engaging in peer training use of insider knowledge to
facilitate production commitment to organizational goals giving extra effort freely
Both measures are global constructs aggregated to the interval level and
standardized
The table reports the results of a series of ordinary least squares regression equations
with standardized coefficients Explain the meaning of the statistics presented What
do these statistics tell us generally about the relationship between resistance
behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows
Anomie Index -standardized interval level measure tapping multiple dimensions
The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)
F5 Researchers collected data from a sample of 350 companies on the following
variables
size (measured as number of employees)
Business Strategy (a nominal variable with 2 response options low-cost provider or
differentiator)
HR Strategy (a nominal variable with 2 response categories High commitment or
low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

I2 A study examined the effects of gender and pre-training motivation on the transfer of
training in terms of improved performance for 123 new industrial managers The
training was on supervisory skills and the dependent variable was based on the
appraisal of the supervisors performance before the training and three months after
the training The performance appraisal data were collected for research purposes
only and resulted in a total transfer score from 1 to 25 with 1 being low Pre-training

mirrors Explain both sides of the debate and then lay out the role of meta-analysis
as you see it within the time span of your career as an academic To do this use
examples of already written (or yet to be written) articles as models
J5 A frequent criticism of non-quantitative research summaries (literature reviews) is
that researchers do not carefully examine how particular research designs might have
affected the statistical outcomes of the studies included in the literature review Meta-
analysis however allows one to statistically examine such effects Assume you are
conducting a meta-analysis of the relationship between leader behaviors and group
productivity Briefly describe the steps you would take in conducting a meta-
analysis What aspects of the original research designs would you examine in your
meta-analysis What steps would you take in gathering and coding data to enhance
the credibility of your analysis

measures is the multi-trait multi-method matrix developed by Campbell and
Fiske (1959) Briefly describe how this matrix is obtained or constructed by a
researcher and then describe how each of the elements of the matrix is used to
demonstrate the reliability andor construct validity of the measure(s)

and discuss the assumptions of the general linear model Multiple regression
ANOVA and principle components (factor) analysis are based on the general linear
model For each of those three statistical procedures describe and discuss the
following
a The type of data necessary for using the technique appropriately

O) Exploratory Factor Analysis and Confirmatory Factor Analysis
O1 Contrast Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis
(CFA) Give an example for the appropriate use of each of the above analyses
What is the role of theory in the two factor analyses
IC
O2 Compare and contrast Exploratory Factor Analysis (EFA) with Confirmatory TH

assumptions usage and limitations
O3 How do exploratory and confirmatory factor analysis differ What are the
advantages and disadvantages of each
O4 Describe the differences between exploratory factor analysis (EFA) and
confirmatory factor analysis (CFA) When would you use one verses another
Are there ways to use EFA in a confirmatory way Can you use CFA in an
exploratory way Also describe the difference in principal components analysis
(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression
O6 The basic factor analysis model can be represented by the matrix algebraic
equation A B = C

information in each matrix and its purpose
(2) For what purpose do researchers use factor analysis Explain In the process
provide a very brief description of a study for which factor analysis would be a
useful data analytic technique
O7 Factor analysis is an important statistical technique in organizational research
Describe factor analysis as an analytical tool including the following issues
a the reasons for using factor analysis
b the type of data necessary for using the technique appropriately
c the type of quantitative output that results from applying the technique
d how a researcher would use the output in his or her research
e how confirmatory factor analysis is different from exploratory
f the important issues and problems in using the technique
P) Structural Equation Models
P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)
Please comment on these restrictions versus access argument Which side do you
take
What are the strengths of SEM Give some examples
What are the weaknesses of SEM Give some examples

way analysis of variance In view of Dr Deltas design answer the following
questions
How sound is Dr Deltas design Comment on the weaknesses of the design
I) Interrupted Time Series Design
I1 What threats to internal validity are and are not ruled out by an interrupted time series
design that includes the introduction of a treatment and its removal at a subsequent
time period List and explain In the process be certain that you provide a diagram
that illustrates such a design
J) Validity Some Questions are about the validity of a measure others about experimental validity)
10) Identify four threats to internal validity and briefly describe what they mean
J1 It was some time ago that the tripartite view of validity was abandoned in favor of a
unitarian view in which different evidentiary bases for validity might be put forward
Binning amp Barrett (1989) represent an attempt to place multiple evidentiary bases into a
single framework Cook amp Campbell (1979) describe four aspects of validity but they
arent really meant to represent evidentiary bases Adding to the confusion is the fact
that while Binning amp Barrett and Cook amp Campbell use some of the same terms these
two pairs of authors clearly mean different things by these terms and intend for them to
be used in different ways Your task is to 1) Describe the evidentiary bases discussed
by Binning amp Barrett 2) Describe the aspects of validity described by Cook amp
Campbell 3) Describe the similarities and differences between the two lists including
the different purposes served by the two lists and 4) Present a single framework that
incorporates both This last task is the most important of the four
J2 What are the types of validity How would each affect an empirical study IC
J3 Define both internal and external validity Which is more important (it is not okay to
say that they are equally important) Defend your reasoning
J4 Why might someone argue that the construct validity of a measure can never really be
established
J5 Describe each of the following forms of validity content convergent discriminant
criterion-related and construct How is each assessed How do they related to each
other Which is most important (Make sure you defend your answer)
J6 Define and explain 6 of the 8 types of validity listed below and describe the type(s) of
information each provides Choose one specific type of study as an example (eg
cross-sectional study experiment quasi-experiment simulation ethnography etc) and
compare and contrast the usefulness and importance of each type of validity for that
type of study
-- Concurrent validity
-- Construct validity
-- Content validity
-- Convergent validity
-- Discriminant validity
-- Statistical conclusion validity
-- Internal validity
-- External validity
J7 Designing empirical research has been called making a series of trade-offs
Unfortunately decisions that are made to increase one desired quality (like internal
validity) can also decrease another desired quality (like external validity) For each of
the issues below discuss the concerns involved (ie the trade-off) and identify the
qualities that are being increased or decreased
a laboratory vs field study
b using a 5-item measure vs a 1-item measure
c using a student sample vs a sample of full-time employees
d using a sample of employees from one company of 5000 vs 500 employees from
each of 10 companies
e collecting your data using one method vs collecting your data using multiple
methods
J8 There are four major types of validity in social science internal validity external
validity construct validity and statistical conclusion validity Please address the
following three issues concerning validity
a What is the meaning of the four major forms of validity (ie internal and external
validity construct validity statistical conclusion validity)
b Are there trade-offs that can or must be made among the four types of validity
d Describe how the concept of validity varies across the research traditions of
experimental vs observational research
IC
J9 The quality of research is often assessed by examining validity issues As you are
aware there are numerous typesforms of validity (eg internal and external validity
construct validity statistical conclusion validity) These types of validity address
different aspects of the research process For this question please address the following
issues
a What is the meaning of the four major forms of validity (ie internal and external
validity construct validity statistical conclusion validity)
b Should there be a priority among these forms of validity If yes why If no why not
c Does the concept of validity vary across research traditions (ie experimental vs
observational research) If yes why If no why not
J10 External validity has received considerable attention in the social and behavioral
sciences Some researchers argue we are too concerned with the external validity of our
findings while other researchers argue that we are too unconcerned with external
validity Several points of view have been developed to explain what is external
validity When answering this question please be sure to address at least the following
issues
a Compare and contrast alternative conceptualizations of external validity
b Some researchers have argued that the role of external validity is invariant across
research traditions (ie experimental vs observational research) Defend the
perspective that the role external validity is invariant across these two research
traditions In addition present the weaknesses of this perspective
J11 In designing a research study researchers must consider trade-offs between internal and
external validity Explain what is meant by internal validity and external validity What
is the nature of these trade-offs How would you evaluatedetermine which is more
important internal or external validity for a particular study Why is this such an
important issue in organizational studies
J12 A researcher conducted a quasi-experiment to test the effects of participative decision
making (PDM) on job attitudes of employees Employees from different departments in
a large organization were assigned to either a treatment group (PDM implemented) or a
control group (no PDM) Random assignment was not possible because of work
schedules coordination of tasks etc Thus the design can be considered an untreated
control group design with pretest and posttest and is represented as follows (where
O=observation X = treatment)

100 being extremely satisfied) How amenable are these results to causal interpretation
What is (are) the major threat(s) to internal validity B if any B for this type of design
given these results What steps can be taken to assess the extent of this (these)
threat(s)
K) Data Collection Methods
14) Describe the various methods of data collection (eg survey interview observation etc)
available to a social scientist What are the advantages and disadvantages of each relative to
each other
K1 Within micro organizational research much criticism has been raised concerning
the reliance on self-report survey data What potential problems does self-report
survey research raise How big of a problem do you think this is
K2 There are a number of methods for collecting data (eg survey interview archival
etc) that are available to a social scientistorganizational researcher Discuss each in
terms of their strengths and weaknesses both on their own and in comparison to one
another
K3 Pick an important construct in your favorite area of management research for which
there is some controversy about how it should be measured or operationalized (eg
environmental munificence or growth need strength) Give the prevailing verbal
definition of the construct and analyze the measurement controversy from two
broad angles First discuss how the controversy may or may not stem from claims
about how one measure is better or worse than another because it (or the other) is an
(a) archival record (b) direct observation (c) social report or (d) self-report That is
what are the relative strengths and weaknesses of each of these types of
measurement for the construct youre discussing Second discuss the construct
validity of the most commonly used measure(s) of this construct To answer this
second part you need to discuss just what construct validity is and how it can or
cannot be demonstrated In the situation you describe what could be done to
demonstrate or improve the construct validity of existing measures
K4 Interviewing in some form has been the workhorse for data collection in a variety
of research traditions positivistquantitative ethnographic feministpost-modernist
and increasingly historical research While each tradition elicits information from
respondents the goals and processes involved in interviewing vary considerably
across research traditions Discuss the purposes of the interview the relationship
between data and theory the roles assumed by the interviewer and the respondent
and the relevant criteria for assessing the validity and reliability of the information
obtained In addition compare and contrast the use of the interview as a data
collection method in the positivistquantitative tradition with its use in one of the
alternative traditions
L) Common Method Variance
L1 Many of us have had concerns about the reviews of our survey research which
suggest that data analyses of surveys are biased because of common method
variance effects of individual differences such as negative mood negative
affectivity and social desirability and the reliability and validity of the constructs
we are attempting to measure Define how these problems affect a research issue in
organizational behavior and the steps that might be taken to minimize such potential
criticisms of papers based on analyses of self-reported data through survey
instruments
L2 In a series of papers by Spector (1994) Schmitt (1994) and Howard (1994)
published in the Journal of Organizational Behavior arguments were provided for
and against the use of self-report questionnaire measures One of the issues
discussed that could limit conclusions drawn from relationships observed using self-
report measures was method variance What is meant by method variance what are
its sources and what impact is it expected to have on research findings
M) Sampling
M1 The manufacturing census samples all plants of 250 employees or more For
plants of 5-249 employees it takes a size proportional sample Plants of 1-4
employees are not sampled What challenges does this sampling method provide
to researchers What could you do to account for these problems if you were
TH
studying organizational (not plant) growth
M2 New York State has approximately 250000 employees in over 70 state agencies
commissions and boards ranging in size from approximately 50 to over 5000
employees Assume that you wanted to draw a representative sample of 1000
employees Describe two ways that you could draw such a sample and briefly
describe the advantages and disadvantages of each of these sampling approaches
IC
M3 The director of a national non-profit agency with approximately 10000
employees located primarily in regional offices in each of the 50 states the
United States has approached you and asked you to develop a study
(organizational survey) of organizational culture within the agency The agency
is about to embark on a variety of change initiatives including developing team
structures and the study is meant to examine various elements of organizational
culture that are potential barriers to change The director has indicated that he
would like to have the data analyzed at both the individual and office level of
analysis Because of funding limitations the agency will only be able to send the
survey to 1000 employees The director has indicated that there are three ways
of sorting employees all employees listed alphabetically all employees listed
alphabetically by state and all employees listed alphabetically by region (there
are between five and ten regions per state) Given these three ways of sorting
employees describe at least three different sampling approaches and the
advantages and disadvantages of each
M4 In your role as Teacher of Organizational Studies you are asked to prepare a
tutorial for beginning doctoral students on sampling design Assume that this
tutorial is part of a basic class in research design and that students in this class
have had a basic statistics course up to and including multiple regression Your
tutorial should focus on briefly defining and explaining the differences between
probability and non-probability samples You should make sure to present and
describe several types of probability samples (eg random systematic
stratified etc) and non-probability samples (eg convenience snow-ball quota
etc) and discuss general principles for when to use a probability vs a non-
probability sampling design For each sampling design you should also provide
at least one clear example of a situation where this type of sampling design is
appropriate
N) Cross-Cultural Research
N1 Discuss the problems in conducting cross-culturalnational comparison in terms
of (1) conceptualization and (2) research design and data collection
Define the three levels of measurement invariance How would the problems that
you have identified in part (a) affect measurement invariance How would you
examine measurement invariance by confirmatory factor analysis
TH
N2 Explain why using national boundaries as independent variable in cross-cultural
studies may not be appropriate in terms of theory and research methods What
alternative ways would you recommend
IC
O) General
O1 In your readings research has been described as choices among conflicting goals
(desiderata) For instance when choosing among research strategies a researcher
must choose among the desiderata of precision realism and generalizability The
trade-offs among desiderata occur for all aspects of research that is for the selection
of theories the treatment of independent variables research strategies the selection
of the problem to study rules of evidence for determining the meaningfulness of a
research finding and even the frameworks that describe the research process
Discuss what you see as the major trade-offs for each of the following aspects of
research That is discuss what you see as the major strengths and weaknesses
(advantages and disadvantages) of each aspect
a The trade-offs between internal and external validity
b The manipulation of the independent variable vs the observation of the
independent variable
c Basic vs applied research
3 DESIGNING A RESEARCH STUDY
A) General (Research Design)
3) Why is control so important in research design What are the different ways it can be
achieved (give a brief description of each control method) What are advantages and
disadvantages of each
A1 It has become almost a truism to note that the choice of methods influences theory
and questions data and conclusions (the causal direction might also be reversed)
Briefly discuss how the methods used have influenced research in any two of the
following areas leadership power and politics organization culture organization
justice Compare and contrast as possible Suggest some potentially fruitful
methodological directions for future work in these same topical areas and dont be
shy about reflecting on broader issues of how the field of organizational behavior
constructs its realities Lastly tie your discussion and reflections back to your own
future as a researcher what lessons or guidance do you derive from your
understanding of these issues
A2 Characterize as fully as possible what you see to be the methodological approach or
approaches in strategic management research Is there a dominant method or a wide
variety Discuss the reasons for the situation What are the advantages benefits etc
of the approach(es) in use What assumptions (ontological epistemological
ideological) do they embody Are current efforts ideal or at least adequate Are
there other approaches that could be useful If so how might researchers be
encouraged to use these as well If you see no advantage to more variety in
methodological approach support that point of view
A3 Describe a research question or area of interest to you and why you think it is not
only of interest but significance Using your understanding of research methodology
describe two ways of pursing the question that are as divergent on as many
dimensions as you can imagine Describe the advantages and disadvantages of each
approach How strong a link or fit is there between a research question and a
method
A4 In his 1957 article entitled The two disciplines of scientific psychology Cronbach
discussed the assumptions goals and methods used in experimental methods and
correlational methods in psychology
a According to Cronbach what is the main difference between the two disciplines
b Discuss the strength and weaknesses of each discipline
c What if anything could be done to improve the situation
B) Designing a Research Study
B1 Cook and Campbell describe the experiment as the research design with the
greatest methodological rigor However given the constraints present in most
organizations I-O Psychologists cannot often conduct experiments in applied
settings and must settle for techniques with less control than experiments
Describe a study to investigate the relationship between participation in a
supervisor training program and work performance which could realistically be
conducted in an organization If an experiment is not possible describe how you
would go about maximizing your ability to draw valid conclusions from your
design
B2 The XYZ Co has recently developed a sexual harassment web-based training
program The developers claim the program will cut training time and costs and
will be as effective or more effective than classroom-based sessions They
believe that this will be due to the increased availability of the program and the
ability for participants to review program material on demand Before the XYZ
Co developers launch this product they want you to determine if their claims
have merit Explain how you would design a study for this purpose
B3 Research suggests that demographic diversity improves group creativity but
reduces group efficiency Some argue that demographic diversity is just a proxy
for value and experience diversity and that demographic diversity on its own is
meaningless Design a test to settle this argument
TH
B4 E-mail has become a common form of communication in organizations and is
used for both formal and informal communication Because it has become so
IC
popular some people complain that the frequent use of e-mail leads to
miscommunication because they receive communications in e-mail that should
be accomplished through face-to-face or telephone conversations where there is
an opportunity for interaction You are interested in looking at this
phenomenon You are most interested in describing how e-mail is used for both
formal and informal communication and in examining the effect of the e-mail
use on organizational communication effectiveness Design empirical research
to address those issues
Describe your study in detail thoroughly explaining the research design
sampling plan data collection procedures ethical issues and proposed data
analysis for your research design Be sure to discuss the internal and external
validity of your research Which validity threats are ruled out and which
remain
REMEMBER Be thorough Your research design should demonstrate that you
are a competent researcher who is knowledgeable about the proposed research
methodology or methodologies Therefore be sure that you carefully describe
and give technical explanations for each component of your research
B5 Choose a specific situation involving employee selection eg artists for an
advertising agency (a) What strategy would you use in selecting the selection
measures (b) How would you combine the measures eg which measures
would you combine in a compensatory manner and which is a noncompensatory
manner (c) How would you assume test fairness defining various measures of
the term (d) How would you make final selections (e) How would you
validate your procedure (f) What considerations would enter in if your
company were too small to provide validation data (g) What difference would
it make if you were developing a procedure for deciding whether trainees
should be promoted as opposed to making new hires Please note--emphasize
but do not limit yourself to statistical issues
B6 There is evidence in the marketing literature of a non-monotonic relationship
between the expectations that customers have for retail service and their
eventual level of satisfaction with that service That is as a customers
expectations for service increase so does their eventual service satisfaction --
up to a point After that point the greater the expectations the lower the
eventual satisfaction Develop a hypothesis that includes a moderator variable
that might account for this evidence Give some reasonable rationale for it State
your hypothesis verbally as an equation as a directed graph (circle amp arrow
diagram) and as an X-Y function chart Discuss how it would or would not be
possible or useful to test your hypothesis via a laboratory experiment In your
discussion cover how and why a researcher could (not) manipulate the
independent constructs involved (mode X) whether or not random assignment
to conditions (mode R) is possible (including how may conditions would be
necessary) which alternative constructs could or could not be controlled (mode
K) and which constructs should be measured (mode Y)
B7 Assume you are the chairperson of a committee that must evaluate
undergraduate programs at your university Your task as chairperson is to
devise an approach (a design a research strategy a set of measures) that will
allow you to evaluate undergraduate programs Make sure that your approach
can be used in the future and at other comparable universities When developing
your plan be sure to address at least the following issues
a the type of design you would select Compare and contrast the selected design
with another possible design
b the type of research strategy you would select Compare and contrast with
another possible strategies
c discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
B8 Assume you are an organizational research design expert assigned to the
Strategic Planning Department of a large multi-national manufacturing firm
The Department has developed a new PC-based software package called
STRATPACK The software (and a one-week training course to learn how to
use it) is intended to improve the long-range planning ability of middle and
upper-level managers
Your job as research design expert is to devise research (a design a research
strategy a set of measures) that will allow you to evaluate the effectiveness of
the STRATPACK program Describe a research design for evaluating the
program Make sure that your research approach can be used in the future and at
all sites in the company When developing your plan be sure to address at least
the following issues
a discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
b the type of design you would select (eg a design where you manipulate the
independent variable versus observe the independent variable) Compare and
contrast the selected design with another possible design
c how your design deals with the major forms of validity Be sure to examine at
least internal external and construct validity
B9 Assume you are a consultant hired to evaluate the effectiveness of an industrial
safety program undertaken by a large manufacturing organization The safety
program is a behavioral one that provides rewards such as monetary bonuses or
extra paid vacation days for safety behaviors in terms of accident-free days
weeks etc Your task is to devise an approach (a research strategy a design a
set of measures and a general analysis strategy) that will allow you to evaluate
the safety program Because of the potential for the influence of many
extraneous variables on any safety program it is difficult to design research a
single cross-sectional study than can evaluate the impact of a single safety
program How would you design a study to evaluate the impact of the safety
program When developing your plan be sure to address at least the following
issues
a the type of research strategy you would select Compare and contrast with
another possible strategies
b the type of design you would select Compare and contrast the selected design
with another possible design
c discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
B10 One of the most important areas of research is forecasting of human resources
needs based on strategic positions of organizations For example NY State must
carefully forecast its human resources needs as it proceeds with significant lay-
offs of state employees Future human resources needs are generally evaluated
by either statistical ie regression or simulation or clinical judgment i e
supervisors judgments methods
a Design a single study that addresses the empirical question of whether
statistical or judgmental methods are better for forecasting human resources
needs You may discuss a program of research but please be quite specific in
your description of the first study
b What are the critical methodological issues in doing this kind of research
c What are the critical applied (or practical) issues in doing this research
d Are the issues in b and c related
B11 In the past decade computinginformation technology has changed many
aspects of organizational life For example the technology can make increased
decentralization possible by improving communication between central offices
and field offices Computer networks and word processors can enhance group
empowerment by making it possible for team members to create and edit
written group products quickly even if the individuals are at different locations
Some have argued that computinginformation technology will foster the
paperless productive office nevertheless others argue that the technology only
increases paper and reduces office productivity You are applying to the
National Science Foundation for a grant to conduct research that examines the
impact of computing information technology on organizational decision
processes The NSF application procedure imposes five basic requirements that
your research design must fulfill in order to receive funding Note A very
significant factor affecting NSF grant decisions is a clear demonstration that the
researcher is knowledgeable about the research methodology used Write your
response to each of the following five grant requirements Be sure not only to
respond to the requirement but also to demonstrate your research
competence
1You must design a study that uses two different methods
(interviewobservation survey experiment or quasi-experiment) Describe your
two methods in detail and provide a rationale for the key elements (eg
sampling data collection proposed analysis) of your methods Be sure to
discuss and evaluate the internal and external validity of both methods
2 As part of your research design you must select a conceptual (latent) variable
central to your proposal (use centralization of decision making as your
variable) and describe how you will develop your own measure (You may not
simply use off the shelf instruments)
3 You must describe how you will test for the reliability of the measure
(centralization of decision making) you developed in step 2 The NSF insists
that you describe how you will evaluate both the temporal stability and the
internal consistency of your measure Be sure to discuss what temporal stability
and internal reliability mean and how they are related
4You must describe how you will assess the validity of the measure
(centralization of decision making) you developed in step 2
5 NSF requires a brief statement and defense of the philosophy of science
underlying your research Discuss your position and show how your research
design is consistent with your philosophy
B12 Many organizations in the United States economy have installed some form of
Empowered Teams as an alternative or supplement to traditional bureaucratic
structure Preliminary evidence of the effectiveness of empowered teams
however is mixed--some organizations have claimed success and others have
reported failures The evidence however is predominantly anecdotal--written
for trade magazines by the organizations themselves There are few rigorous
empirical studies assessing the effectiveness of empowered or self-managed
teams You are applying to the United States Department of Labor (USDOL) for
a grant to conduct research that examines the effectiveness of empowered
teams The application procedure of the USDOL imposes three requirements
that your research design must fulfill in order to receive funding Write your
response to each of the three grant requirements The importance of each section
is implied by the evaluation points allocated by the USDOL to each of the three
requirements given in parentheses
1 (50 points) Your study design for assessing Empowered Team effectiveness
must use two different methods (interview observation archival analysis
survey simulation experiment or quasi-experiment) Describe in detail and
thoroughly explain the sampling plan instrumentation data collection
procedures and proposed data analyses for both methods Be sure to discuss the
internal and external validity of both methods and how the two methods
complement one another
2 (30 points) As part of your research design you must select one conceptual
(latent) variable central to your proposal and describe how you will develop
your own operationalization of the measure (You may not simply use off the
shelf instruments) Use the concept of group morale to demonstrate your
operationalization methodology Be sure to explain very explicitly to the
USDOL how you will assess the validity and reliability of the group morale
measure you are developing
3 (20 points) The USDOL traditionally has funded research conducted only
within the general paradigm of logical positivism but now is more open to other
research paradigms as well Your grant proposal must provide a statement and
defense of the explicit philosophy of science underlying your research Describe
your philosophy of science and show how your research design is consistent
with your philosophy
REMEMBER Be thorough You not only must design effective research but
you also must demonstrate to the USDOL that you are a competent researcher
It is absolutely vital to the USDOL that the principal researcher is
knowledgeable about the proposed research methodologies Therefore be sure
that you always carefully describe and give technical explanations for each
component of your research design and explain all technical terms (eg
Cronbach alpha KR-20 Likert scale)
B13 Assume that you are working as part of a research team that is responding to a
RFP (Request for Proposals) from a funding agency for research on work
socialization and newcomer adjustment The RFP calls for rigorous field
research that tests the effectiveness of theory-based interventions aimed at
facilitating the adjustment of new organizational members to complex andor
stressful work conditions The major goal of your teams research is to test the
effectiveness of a self-regulation intervention which trains newcomers to
identify and use relevant social information and cues to regulate work behavior
Your group hypothesizes that self-regulation training will be more effective
than other common treatments or interventions (eg realistic job previews
institutionalized socialization tactics)
You have been included in the team because of your methodological expertise
Your role is to design a rigorous field experiment or quasi-experiment to test he
effectiveness of the self-regulation training program REMEMBER THE
MAJOR CRITERION FOR FUNDING IS THE RIGOR OF THE RESEARCH
DESIGN Design a field study to include in the grant proposal Your proposal
should contain the following two sections
1 Study Design Construct and describe in detail an experimental or quasi-
experimental design to test the effectiveness of your intervention Describe in
detail the experimental groups (including how they will be constructed) the
research setting the sampling plan for study participants the treatment
manipulation and the data collection procedures Also indicate any control or
nuisance variables that may be measured
After describing the procedures write a justification of the design What threats
to validity does it rule out or limit and what threats to validity remain
II Measurement Describe the steps you would take to achieve valid and
reliable measure of the latent (conceptual) variable worker adjustment Your
team feels that as part of the proposal you must develop an original
operationalization of adjustment (thus you cannot simply use existing off the
shelf measures) Indicate in adequate detail how you would operationalize the
measure and indicate how you would demonstrate reliability and validity
B14 In describing their notion of the collective mind Karl E Weick and Karlene H
Roberts note Our focus is at once on individuals and the collective since only
individuals can contribute to a collective mind but a collective mind is distinct
from an individual because it inheres in the pattern of interrelated activities
among many people (p 360) Collective mind is not indexed by within-group
similarity of attitudes ideas or activities A collective mind is one in which
many people or many groups integrate their different attitudes ideas and
activities heedfully As Weick and Roberts note People act heedfully when
they act more or less carefully critically consistently purposefully attentively
studiously vigilantly conscientiously pertinaciously (p 361)
The idea of the collective mind as heedful interrelating is developed in the
following excerpt When people make efforts to interrelate these efforts can
range from heedful to heedless The more heed reflected in a pattern of
interrelations the more developed the collective mind and the greater the
capability to comprehend unexpected events that evolve rapidly in unexpected
ways When we say that a collective mind comprehends unexpected events we
mean that heedful interrelating connects sufficient know-how to meet situational
demands For organizations concerned with reliability those developments
often consist of unexpected non-sequential interaction (p366)
An example of heedful interrelating occurs as a pilot lands herhis aircraft on the
deck of an aircraft carrier The pilot does not actually land She is recovered
A recovery is an interrelated set of activities among air traffic controllers
landing signal officers the control tower navigators deck hands the helmsman
driving the ship etc These activities can be interrelated more or less heedfully
depending on the care with which the different units contribute represent the
situation and subordinate their activities to the single purpose of successful
recovery (p 363)
You are to design a two-part study
Part I You are to design a measurement study which assesses heedful
interrelating (ie collective mind) with a quantitative measure in a replication
of an aircraft carrier flight deck or other situation of your choosing Describe
your research strategies including operationalization of the variable selection of
the sample subjects data collection data analysis and so on for the purpose of
developing a measure of heedful interrelating
Part II Using the measurement tool developed in Part I and any other tools as
needed describe how you would design a study which would compare heedful
interrelating across organizations Choose at least one macro-organizational
variable (eg technology environment) as your basis of comparison Here you
must describe how you would make your selection of organizations to be
compared your data collection procedure data analysis and so on
B15 Many organizations in the United States have installed cross-functional teams to
counteract the silo mentality of traditional bureaucratic structure Preliminary
evidence of the effectiveness of cross-functional teams however is mixed --
some organizations have claimed success and others have reported failures The
evidence moreover is predominantly anecdotal--written for trade magazines by
the organizations themselves Since there have been few rigorous empirical
field studies assessing the effectiveness of cross functional teams the National
Science Foundation has decided to fund research on the topic
Assume that you are submitting a research proposal to NSF for a grant to
research the effectiveness of cross-functional teams Describe in detail and
thoroughly explain the research design sampling plan data collection
procedures ethical issues and proposed data analysis for your research design
Be sure to discuss the internal and external validity of your research Which
validity threats are ruled out and which remain NSF also requires that you
provide a statement and defense of the explicit philosophy of science underlying
your research Describe your philosophy of science and discuss how your
research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but
you must also demonstrate to NSF that you are a competent researcher It is
absolutely vital to NSF that the principal researcher (you) is knowledgeable
about the proposed research methodologies Therefore be sure that you always
carefully describe and give technical explanations for each component of your
research design and explain all technical terms (eg Cronbach alpha KR-20
Likert scale)
B16 Assume that you are submitting a research proposal to the Department of
Commerce (DoC) for a grant to research the effectiveness of virtual work teams
A virtual work team is a leaderless collection of individuals who are
geographically separate from one another and share their expertise using
internet media such as a listserver or Lotus notes The DoC requires that the
researcher use both qualitative and quantitative methods to gather data Describe
in detail and thoroughly explain the research design sampling plan data
collection procedures ethical issues and proposed data analysis for your
research design Be sure to discuss the internal and external validity of your
research Which validity threats are ruled out and which remain The DoC also
requires that you provide a statement and defense of the explicit philosophy of
science underlying your research Describe your philosophy of science and
discuss how your research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but
you must also demonstrate to DoC that you are a competent researcher It is
absolutely vital to DoC that the principal investigator (you) is knowledgeable
about the proposed research methodologies Therefore be sure that you always
carefully describe and give technical explanations for each component of your
research

on this topic for which validity (or set of validities) is most critical at this juncture
in the field Finally given your critique and assessment design a follow-up study
that improves upon the key validity (or validities)
5 MEASUREMENT
A) Measurement Terms
A1 There are four levels of measurement rigor in management research Discuss each
one What properties do measurements at each level have (ie how much
information do the numbers from each level of measurement convey) How can the
numbers be changed (transformed) and still retain the properties of their
measurement level Pick one construct from a favorite research domain and give an
example of an operationalization of that construct at each of the four levels of
measurement rigor (provide arguments about why you think those examples reflect
each level) Lastly treat each examplelevel as a dependent variable in some
statistical analysis Given an example of a statistical technique appropriate for
analyzing data at that level of measurement rigor
A2 Define (and discuss important features or issues concerning) the following
constructs measurement (Define any six terms)
1 Construct validity 6 Item analysis
2 Likert scaling 7 Semantic differential
3 Cronbachs alpha 8 True score
4 Unobtrusive (trace) measurement 9 Generalizability theory
5 Interval scale 10 Criterion-related validity
11 Sociometric choice measures
B) Operationalization
B1 a) You are conducting a study which requires you to measure Hong Kong real
estate agents self-assessment of performance Since there is no existing
measurement available you have to develop the instrument by yourself
Describe how you would develop the measurement assuming that you have no
idea of how many dimension the construct has
b) Suppose you have developed an instrument consists of 20 questions
measuring 4 dimensions (5 items per dimension) from (a) You collected data
from another 300 real estate agents to validate your instrument Explain how
TH
you would use structural equations model (SEM) to examine the reliability and
validity of the instrument What are other concerns about reliability and validity
that are not addressed by this approach
B2 The research and business world have been fascinated with the concept of
organizational culture However operationalizing this construct has been a
difficult task Discuss the ways in which the construct has been operationalized
(eg technique static v dynamic sample selection generalizability) Critically
analyze each of these methodologies Then choose a methodology you would
use to examine organizational culture and defend your choice Describe how
you would study culture and what more would be known about culture as a
result of your study
B3 Suppose you are setting out to develop a new measure of a construct You want
this measure to be used in survey research and you want to establish its validity
and reliability Your goal is to have at the end of the process a measure that is
defensible and likely to be widely accepted by other researchers studying that
construct What steps would you take to conduct such a program of research
For each step explain the purpose of that step explain why that step is
important explain what methods and statistical procedures you would employ at
each step and explain what evidence you would hope to gather at each step
B4 Assume you are interested in constructing a new measure of (fill in with a
relevant variable from your field) Detail the major concerns that need to be
addressed and the steps that need to be taken in working toward validating this
new measure
B5 Assume that you recently read an article on workplace violence which you
found very interesting The authors argued that one of the predictors of
workplace violence was a construct called propensity to be violent and used a
one-item measure as follows How likely are you to become violent when
provoked You had serious doubts about the authors measure and decided to
develop your own
(a) How would you go about developing items to measure propensity to be
violent
(b) How would you determine whether the instrument was reliable
How would you determine whether the instrument was valid
B6 A concern in organizations is retirement of baby boomers within the next 5 -
10 years This concern is focused on the loss of older employees with skills
critical to the core business functions of organizations In order to continue to
have employees with those critical skills it seems necessary to retrain some
older workers However past practice in most organizations has been not to
retrain older workers for a variety of reasons mostly financial A researcher
working for the Human Resources Department of a large corporation - 13500
employees in 12 different plant locations - hypothesizes that the major reason
for not retraining older workers is ingrained in the culture of the corporation
IC
The researcher feels that older workers are not as highly valued as younger
workers in terms of their potential usefulness after retraining The researcher
searched the literature but found nothing in the existing literature to measure
the cultural value construct What should the researcher do to establish a reliable
and valid self-administered paper and pencil measure of this construct namely
the value of retraining older workers
a Please describe and explain the steps in temporal order that the researcher
must follow to develop a measure
b How would you evaluate the measure based on the technical requirements of
reliable and valid measurement as well as any practical issues in using the
measure considering the size of the employee population
B7 Assume that you are going to conduct empirical research to assess the role that
the complexity of an organizations manufacturing technology plays in
determining the level of centrality of decision making in the organization
Describe and justify the steps you might follow to develop an operationalization
of the concept of technological complexity What standards would you use to
determine if your operationalization is valid
B8 Organizational researchers have several strategies available to them for
gathering information (eg self-report measures archival measures direct
observation and trace measures) Assume that you are going to conduct
empirical research to assess the role that the structure of the organization plays
in determining the level of organizational effectiveness Briefly review the
strengths and weaknesses of the basic strategies (that is self-report measures
archival measures direct observation and trace measures) for measuring
organizational effectiveness Next describe and justify the steps you would
take to develop an operationalization of the concept of organizational
effectiveness What standards and procedures would you use to determine if
your operationalization is valid
B9 One of the most important topics of recent research has been stress in the work

this new scale With regard to testing and evaluating be sure to consider the
role of factor analysis (both exploratory and confirmatory) and item analysis
Also you will want to make sure that your new multidimensional scale shows
evidence of validity (several kinds) and reliability so be sure to examine these

C10 Schmidt and Hunter (1996) described several types of measures typically used in
organizational research and identified the type(s) of measurement error affecting
each of them in various situations For each measure below indicate the types of
error and sources of error that are most likely to affect it Then indicate what
could be done to reduce errors of measurement andor what can be done to
control for errors statistically

worker)
d Aptitude tests taken as part of the hiring process
C11 Suppose you had conducted research on the relationship between organizational
commitment and rigidity of organizational structure in 200 firms Your measure
of rigidity was based on number of organizational authority levels and the degree
to which written organizational rules existed and defined role behaviors for
employees Thus an organization with a large number of organizational levels
and specific written policies defining appropriate role behaviors for employees
would score high on rigidity of organizational structure After analyzing your
data you find that there is a statistically significant negative correlation between
commitment and rigidity which is consistent with your hypothesis However the
reliabilities for your two measures are
(1) commitment = 23 (2) rigidity = 83
How should you interpret your results What could you do to fix this situation
Describe the specific steps (in order) you would follow to develop a more
reliable measure of commitment
C12 (a) Define the concept of reliability (of measures) in a clear concise and
accurate manner (b) Provide a formula that expresses the reliability of a measure

research literature This type of research raises many issues and presents many
challenges in terms of designing the research measuring variables and collecting
and analyzing the data Assume that you are interested in aggregating data (eg
from the individual to the group or from the firm to the industry) for one or more
variables What are the major issues you will need to deal with
D3 A researcher wants to measure organizational climate for continuous learning
Organizational climate is operationalized as a shared consensual aspect of the
organization -- the shared perception among employees that the organization values
and supports continuous learning Describe how you would measure organizational
climate in this case Specify (a) the level (ie individual group organization) at
which the construct exists (b) the level at which you would measure the construct
and (c) the procedures that you would use to establish that measurement is aligned
with theory (ie the construct validity of the measure)
E) General (Measurement)
E1 Studies in organizational behavior research often rely on single-item measures of
key constructs The use of single-item measures has long been criticized based
on the premise that single-item measures are unreliable However Wanous
(Wanous amp Hudy 2001 Wanous amp Reichers 1996 Wanous Reichers amp Hudy
1997) has recently argued that single-item measures can exhibit adequate
reliability Wanous based this conclusion on a procedure for estimating the
reliability of single-item measures using the classic formula for correction for
attenuation Subsequent studies have yielded mixed results regarding the
conclusions of Wanous (eg Loo amp Kells 1998 Nagy 2002) and the veracity
of the perspective advocated by Wanous remains in question Summarize and
assess the arguments for and against the use of single-item measures and
evaluate the procedure and evidence offered by Wanous regarding the reliability
of single-item measures Based on your assessment and evaluation develop
recommendations regarding the use of single-item measures in organizational
behavior research

E2 Ipsative measures have become prevalent in organizational behavior research
Ipsative measures ask respondents to answer questions relative to one another
such that the scores for all questions sum to the same constant for all respondents
Examples of ipsative measures include rankings Q-sorts and the allocation of a
fixed number of points (eg 100) across a set of response options Ipsative
measures may be contrasted with absolute measures which ask respondents to
answer questions independently from one another Absolute measures are
exemplified by rating scales using an interval or ratio numeric response format
The relative merits of ipsative and absolute measures have been debated for
decades (eg Cornwell amp Dunlap 1994 Hicks 1970 Johnson Wood amp
Blinkhorn 1988 Saville amp Wilson 1991 1992) yet the fundamental issues
underlying this debate have not been adequately addressed in organizational
behavior research For example measures of organizational culture and values
are often ipsative and some researchers advocate these measures over absolute
measures (eg Meglino amp Ravlin 1987 OReilly Chatman amp Caldwell 1991
Ravlin amp Meglino 1987 see also Rokeach amp Ball-Rokeach 1989) Review the
relative merits of absolute and ipsative measures Based on your review which
form of measurement is most appropriate and why Do your conclusions depend
on the construct being measured If so what types of constructs are best suited to
ipsative measures and what types are best suited to absolute measures Next
apply your conclusions to the measurement of culture and values in
organizations What specific arguments have been advanced in favor of ipsative
measures of culture and values How sound are these arguments Should ipsative
measures be used in the study of organizational culture and values If not how
can absolute measures of culture and values be developed that address the
concerns voiced by advocates of ipsative measures Provide a specific example
of the type of measure you would propose

facets of a concept Although such measures are prevalent and in some cases are
advocated (eg Law et al 1998 1999) they can present a variety of conceptual
and methodological problems Describe the specific problems associated with
measures that use items representing different facets of a concept Compare these
problems with the purported advantages of such measures Conclude by

E5 Suppose Roberta Von Eisenbrick is a researcher interested in the consequences of
AFFECTIVE CONFLICT (AC) in decision-making teams She gets access to a
variety of outcomes assessment committees at each of 87 different schools in
the Dallas Independent School District and gains permission to tape-record two
of their meetings (one in February and one in March) Such committees have
been formed to develop quantitative ways to track pursuit of school goals and
provide accountability to local and state governments These are often divisive
teams with heated meetings because what gets assessed is what usually gets
rewarded After both of these meetings the committee members each
fill out a short questionnaire that contains 20 Likert-type items measuring how
much AC occurred (eg People in our group often get angry with each other)
The individual scores are summed across items then averaged across team
members to come up with a group-level AC score for each of the 87 2
meetings The same procedures are followed for a 5-item measure of Group
Cohesiveness (GC) which is predicted to be reduced by higher levels of AC
Roberta also listens to every tape and from her expert judgment she rates each
groups meetings on the same 20 items Those 20 ratings are summed for each of
the 87 2 meetings Now Roberta is interested in evaluating her measure She
wants it to have excellent psychometric properties including reliability and
construct validity

D) ModeratorsMediators
D1 Moderation and mediation provide different ways to model third variable effects
(a) Please define both of these terms (b) Sketch a conceptual model to show how
each relates to main effects (c) Using variables of your choice please write
hypotheses to reflect both (d) Explain how each is tested analytically
D2 Discuss moderators and mediators Provide an example of how (1) a moderating
variable influences the relationship between the independent and dependent
variable and how (2) a mediating variable influences the relationship between
the independent and dependent variable Describe how you would test for both
moderation and mediation using regression
D3 Many theories in organizational research predict that the effects of one variable
on another are moderated by a third variable Such moderator effects are
typically tested by entering the product of two variables as a predictor after
controlling for the two variables that constitute the product Several researchers
have pointed out that this product is often highly correlated with the squares of
the two constituent variables and have suggested that moderating effects may be
tested after controlling not only for the two constituent variables but also their
squares (eg Cortina 1993 Ganzach 1998 Lubinski amp Humphreys 1990
MacCallum amp Mar 1995) Discuss the strengths and weaknesses of this
approach as compared to methods that use only the product term and its
constituent variables Conclude with recommendations as to when and under
what conditions organizational researchers should test moderator effects with the
squares of the constituent variables in the equation

D4 Assume you are interested in studying relationships amongst three variables X
Y and Z Your first hypothesis posits Z as a mediator of the relationship between
X and Y Your second hypothesis posits Z as a moderator of the relationship
between X and Y Draw the figures depicting each of these hypothesized
relationships and describe (make sure to write regression equations) how you
would test each of these hypotheses
D5 The amount of time and effort that the average person pours into his or her job
has risen steadily over the last two decades such that the average person now is
working one more week per year than the average person in the mid 1970s This
steady increase has fueled research interest in the construct of Job Burnout (JB)
which is an emotional and physical exhaustion associated with ones work
Organizational Stress (OS) the perception of greater demands than available
resources in ones work environment is thought to be one of the chief
antecedents of JB However time spent under OS is thought to make its affects
on JB accumulate or worsen Work Role Withdrawal (WRW) the avoidance of
responsibilities or the deliberate reduction of inputs to ones job is believed to be
the chief consequence of JB
a Formally state these ideas as verbal hypotheses as equations and as a complex
directed graph (circle amp arrow diagram)
b Conceptually what is a mediator Define the term and identify the mediator in
your hypotheses in (a) What elements or steps in a study design (not statistics)
that would be helpful for detecting the mediating relationship that was proposed

subdomains of management Further demonstrate your understanding of
moderator variables by picking which variable in (a) is the moderator Show the
moderating relationship in an X-Y (or multi-layered) chart Again what elements
or steps in a study design (not statistics) would be helpful for detecting the
moderating effect implied above

for differences among the different levels or cells of a categorical variable In your
description you should discuss among other things

recommendations You conduct a well-designed controlled study (details are unimportant) and discover students who use the new book perform 10 better on a standardized subject
matter exam than those using the old book (p = 027) Both books are readily availabe their prices are almost identical and both are equally acceptable to the instructors What is your recommendation to the chair
F1 Attached is the beginning of an article Your task is to write the results section by

reader understand the results of the statistical tests you report and the nature of your
sample (Hint this can be presented in the form of a table)
2 describing and defending your choice of appropriate statistical tests of the
hypotheses and the steps that you would go through in carrying out these tests
3 making up and reporting results of these tests that are consistent with your
descriptive statistics and with any information in the rest of the article about the
results found (Hint this can be presented in the form of a table)

may want to note any relevant threats to validity here
Be sure to state any assumptions you make
F2 Assume that the Personnel Manager of a local firm Ms B dFlandres hired you to
analyze some data that her assistants had collected over the past several years The
data consist of (a) job performance ratings that were made in June of 1990 and (b)
scores on 25 predictor variables (eg measures of education job experience job
tenure job aptitude personality) that were measured when the individuals were hired
(between April 1987 and May 1988) She had data from only the 110 subjects (60
males and 50 females) who were hired during the period and were still employed by
the firm One objective of your analysis (analyses) is to determine how well the
performance criterion can be predicted by the predictors What strategy would you
use in analyzing the data Describeexplain (b) Is sample size an issue for your
analyses Explain If it is what will you do to deal with problems stemming from
sample size Assume that no additional data can be collected at this time (c) Some
preliminary analyses that you do reveal that five of the predictor variables correlate
(zero-order basis) about 75 with one another Will this influence the analyses that
you use Will it influence the validity of conclusions derived from your proposed
analyses (d) Ms dFlandres is interested in knowing if the predictor variables are
equally effective in predicting the job success of males and females What analysis
or analyses would you do to deal with this issue
F3 Assume that you have been provided with data on 12 conceptually distinct variables
that are moderately correlated with one another at the empirical level The data are
from students in four different college majors ie astronomy (A) biology (B)
criminology (C) and demography (D) The 12 measured variables fall into the
general categories of mental health (tension emotional withdrawal hallucinations
guilt feelings blunted affect and suspiciousness) and job satisfaction (work itself
supervision co-workers pay promotion prospects and working conditions) Your
task is to determine if the individuals in the four college majors differ from one
another on the 12 measured variables

Explain Be specific about the procedures(s) that you would use
(b) What statistical estimate would you use to estimate the extent to which the
groups differ from one another Be specific
F4 The following statistical table published in a recent issue of Work amp Occupations
was taken from an article discussing variables influencing resistance and citizenship
behaviors in the workplace Resistance behaviors include playing dumb withholding
effort work avoidance subverting particular managers and sabotage Citizenship
behaviors include cooperation engaging in peer training use of insider knowledge to
facilitate production commitment to organizational goals giving extra effort freely
Both measures are global constructs aggregated to the interval level and
standardized
The table reports the results of a series of ordinary least squares regression equations
with standardized coefficients Explain the meaning of the statistics presented What
do these statistics tell us generally about the relationship between resistance
behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows
Anomie Index -standardized interval level measure tapping multiple dimensions
The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)
F5 Researchers collected data from a sample of 350 companies on the following
variables
size (measured as number of employees)
Business Strategy (a nominal variable with 2 response options low-cost provider or
differentiator)
HR Strategy (a nominal variable with 2 response categories High commitment or
low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

(a) Prepare a standard analysis of variance (ANOVA) table that is appropriate for this
design Make certain that you specify all effects and the appropriate degrees of
freedom for each effect If you use any abbreviations in your table make certain that
you specify their meaning
(b) Assume that an initial ANOVA analysis found no evidence of an A X B
interaction What if anything would you do with the sum of squares for the
interaction effect
I2 A study examined the effects of gender and pre-training motivation on the transfer of
training in terms of improved performance for 123 new industrial managers The
training was on supervisory skills and the dependent variable was based on the
appraisal of the supervisors performance before the training and three months after
the training The performance appraisal data were collected for research purposes
only and resulted in a total transfer score from 1 to 25 with 1 being low Pre-training
motivation was based on a 12 item Likert scale with an alpha of 86 Two groups
were identified for the pre-training motivation variable - the bottom 13 (low) and the
top 13 (high) Table 1 contains the ANOVA results and Table 2 contains the cell

category as typically implemented has certain advantages and disadvantages
Describe the advantages and disadvantages associated with each approach taking
particular care to enumerate the disadvantages associated with quantitative review
Then offer two ways that meta-analysis might be combined with other analytical
techniques to move beyond the focus of bivariate relationships that is typical of meta-
analysis

scientific laws but that meta-analytic research does What are the arguments in favor
of or against this position In what areas of research (if any) has Schmidts
prediction come closest to coming true
J3 The so-called (by Hunter Schmidt and Jackson 1983) state of the art meta-
analysis method attempts to account for various sources of error that might produce

that a meta-analysis can make to theory building in the organizational sciences (c)
Describe the circumstances that you would consider when deciding whether to
perform a meta-analysis
J4 Meta-analysis has been hailed as a miracle cure and criticized as smoke and
mirrors Explain both sides of the debate and then lay out the role of meta-analysis
as you see it within the time span of your career as an academic To do this use
examples of already written (or yet to be written) articles as models
J5 A frequent criticism of non-quantitative research summaries (literature reviews) is
that researchers do not carefully examine how particular research designs might have
affected the statistical outcomes of the studies included in the literature review Meta-
analysis however allows one to statistically examine such effects Assume you are
conducting a meta-analysis of the relationship between leader behaviors and group
productivity Briefly describe the steps you would take in conducting a meta-
analysis What aspects of the original research designs would you examine in your
meta-analysis What steps would you take in gathering and coding data to enhance
the credibility of your analysis
K) MTMM
K1 One method often used by social scientists to demonstrate the construct validity of
measures is the multi-trait multi-method matrix developed by Campbell and
Fiske (1959) Briefly describe how this matrix is obtained or constructed by a
researcher and then describe how each of the elements of the matrix is used to
demonstrate the reliability andor construct validity of the measure(s)
IC
K2 Describe the logic of the multi-trait multi-method (MTMM) analysis in terms of
the criteria for evaluating the validity of a set of measurement procedures
Interpret the following MTMM in terms of what it might infer about the validity
of the different measurement procedures You may impose any assumptions on
the data you prefer For example you might want to discuss the matrix under the
assumption that traits A B amp C are mutually independent Please justify and
make explicit any assumptions you make

and discuss the assumptions of the general linear model Multiple regression
ANOVA and principle components (factor) analysis are based on the general linear
model For each of those three statistical procedures describe and discuss the
following
a The type of data necessary for using the technique appropriately

assumptions usage and limitations
O3 How do exploratory and confirmatory factor analysis differ What are the
advantages and disadvantages of each
O4 Describe the differences between exploratory factor analysis (EFA) and
confirmatory factor analysis (CFA) When would you use one verses another
Are there ways to use EFA in a confirmatory way Can you use CFA in an
exploratory way Also describe the difference in principal components analysis
(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression
O6 The basic factor analysis model can be represented by the matrix algebraic
equation A B = C

information in each matrix and its purpose
(2) For what purpose do researchers use factor analysis Explain In the process
provide a very brief description of a study for which factor analysis would be a
useful data analytic technique
O7 Factor analysis is an important statistical technique in organizational research

a the reasons for using factor analysis
b the type of data necessary for using the technique appropriately
c the type of quantitative output that results from applying the technique
d how a researcher would use the output in his or her research
e how confirmatory factor analysis is different from exploratory
f the important issues and problems in using the technique
P) Structural Equation Models
P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

parameter estimate bias in structural equation modeling Structural Equation

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)
Please comment on these restrictions versus access argument Which side do you
take
What are the strengths of SEM Give some examples
What are the weaknesses of SEM Give some examples

J7 Designing empirical research has been called making a series of trade-offs
Unfortunately decisions that are made to increase one desired quality (like internal
validity) can also decrease another desired quality (like external validity) For each of
the issues below discuss the concerns involved (ie the trade-off) and identify the
qualities that are being increased or decreased
a laboratory vs field study
b using a 5-item measure vs a 1-item measure
c using a student sample vs a sample of full-time employees
d using a sample of employees from one company of 5000 vs 500 employees from
each of 10 companies
e collecting your data using one method vs collecting your data using multiple
methods
J8 There are four major types of validity in social science internal validity external
validity construct validity and statistical conclusion validity Please address the
following three issues concerning validity
a What is the meaning of the four major forms of validity (ie internal and external
validity construct validity statistical conclusion validity)
b Are there trade-offs that can or must be made among the four types of validity
d Describe how the concept of validity varies across the research traditions of
experimental vs observational research
IC
J9 The quality of research is often assessed by examining validity issues As you are
aware there are numerous typesforms of validity (eg internal and external validity
construct validity statistical conclusion validity) These types of validity address
different aspects of the research process For this question please address the following
issues
a What is the meaning of the four major forms of validity (ie internal and external
validity construct validity statistical conclusion validity)
b Should there be a priority among these forms of validity If yes why If no why not
c Does the concept of validity vary across research traditions (ie experimental vs
observational research) If yes why If no why not
J10 External validity has received considerable attention in the social and behavioral
sciences Some researchers argue we are too concerned with the external validity of our
findings while other researchers argue that we are too unconcerned with external
validity Several points of view have been developed to explain what is external
validity When answering this question please be sure to address at least the following
issues
a Compare and contrast alternative conceptualizations of external validity
b Some researchers have argued that the role of external validity is invariant across
research traditions (ie experimental vs observational research) Defend the
perspective that the role external validity is invariant across these two research
traditions In addition present the weaknesses of this perspective
J11 In designing a research study researchers must consider trade-offs between internal and
external validity Explain what is meant by internal validity and external validity What
is the nature of these trade-offs How would you evaluatedetermine which is more
important internal or external validity for a particular study Why is this such an
important issue in organizational studies
J12 A researcher conducted a quasi-experiment to test the effects of participative decision
making (PDM) on job attitudes of employees Employees from different departments in
a large organization were assigned to either a treatment group (PDM implemented) or a
control group (no PDM) Random assignment was not possible because of work
schedules coordination of tasks etc Thus the design can be considered an untreated
control group design with pretest and posttest and is represented as follows (where
O=observation X = treatment)

K) Data Collection Methods
14) Describe the various methods of data collection (eg survey interview observation etc)
available to a social scientist What are the advantages and disadvantages of each relative to
each other
K1 Within micro organizational research much criticism has been raised concerning
the reliance on self-report survey data What potential problems does self-report
survey research raise How big of a problem do you think this is
K2 There are a number of methods for collecting data (eg survey interview archival
etc) that are available to a social scientistorganizational researcher Discuss each in
terms of their strengths and weaknesses both on their own and in comparison to one
another
K3 Pick an important construct in your favorite area of management research for which
there is some controversy about how it should be measured or operationalized (eg
environmental munificence or growth need strength) Give the prevailing verbal
definition of the construct and analyze the measurement controversy from two
broad angles First discuss how the controversy may or may not stem from claims
about how one measure is better or worse than another because it (or the other) is an
(a) archival record (b) direct observation (c) social report or (d) self-report That is
what are the relative strengths and weaknesses of each of these types of
measurement for the construct youre discussing Second discuss the construct
validity of the most commonly used measure(s) of this construct To answer this
second part you need to discuss just what construct validity is and how it can or
cannot be demonstrated In the situation you describe what could be done to
demonstrate or improve the construct validity of existing measures
K4 Interviewing in some form has been the workhorse for data collection in a variety
of research traditions positivistquantitative ethnographic feministpost-modernist
and increasingly historical research While each tradition elicits information from
respondents the goals and processes involved in interviewing vary considerably
across research traditions Discuss the purposes of the interview the relationship
between data and theory the roles assumed by the interviewer and the respondent
and the relevant criteria for assessing the validity and reliability of the information
obtained In addition compare and contrast the use of the interview as a data
collection method in the positivistquantitative tradition with its use in one of the
alternative traditions
L) Common Method Variance
L1 Many of us have had concerns about the reviews of our survey research which
suggest that data analyses of surveys are biased because of common method
variance effects of individual differences such as negative mood negative
affectivity and social desirability and the reliability and validity of the constructs
we are attempting to measure Define how these problems affect a research issue in
organizational behavior and the steps that might be taken to minimize such potential
criticisms of papers based on analyses of self-reported data through survey
instruments
L2 In a series of papers by Spector (1994) Schmitt (1994) and Howard (1994)
published in the Journal of Organizational Behavior arguments were provided for
and against the use of self-report questionnaire measures One of the issues
discussed that could limit conclusions drawn from relationships observed using self-
report measures was method variance What is meant by method variance what are
its sources and what impact is it expected to have on research findings
M) Sampling
M1 The manufacturing census samples all plants of 250 employees or more For
plants of 5-249 employees it takes a size proportional sample Plants of 1-4
employees are not sampled What challenges does this sampling method provide
to researchers What could you do to account for these problems if you were
TH
studying organizational (not plant) growth
M2 New York State has approximately 250000 employees in over 70 state agencies
commissions and boards ranging in size from approximately 50 to over 5000
employees Assume that you wanted to draw a representative sample of 1000
employees Describe two ways that you could draw such a sample and briefly
describe the advantages and disadvantages of each of these sampling approaches
IC
M3 The director of a national non-profit agency with approximately 10000
employees located primarily in regional offices in each of the 50 states the
United States has approached you and asked you to develop a study
(organizational survey) of organizational culture within the agency The agency
is about to embark on a variety of change initiatives including developing team
structures and the study is meant to examine various elements of organizational
culture that are potential barriers to change The director has indicated that he
would like to have the data analyzed at both the individual and office level of
analysis Because of funding limitations the agency will only be able to send the
survey to 1000 employees The director has indicated that there are three ways
of sorting employees all employees listed alphabetically all employees listed
alphabetically by state and all employees listed alphabetically by region (there
are between five and ten regions per state) Given these three ways of sorting
employees describe at least three different sampling approaches and the
advantages and disadvantages of each
M4 In your role as Teacher of Organizational Studies you are asked to prepare a
tutorial for beginning doctoral students on sampling design Assume that this
tutorial is part of a basic class in research design and that students in this class
have had a basic statistics course up to and including multiple regression Your
tutorial should focus on briefly defining and explaining the differences between
probability and non-probability samples You should make sure to present and
describe several types of probability samples (eg random systematic
stratified etc) and non-probability samples (eg convenience snow-ball quota
etc) and discuss general principles for when to use a probability vs a non-
probability sampling design For each sampling design you should also provide
at least one clear example of a situation where this type of sampling design is
appropriate
N) Cross-Cultural Research
N1 Discuss the problems in conducting cross-culturalnational comparison in terms
of (1) conceptualization and (2) research design and data collection
Define the three levels of measurement invariance How would the problems that
you have identified in part (a) affect measurement invariance How would you
examine measurement invariance by confirmatory factor analysis
TH
N2 Explain why using national boundaries as independent variable in cross-cultural
studies may not be appropriate in terms of theory and research methods What
alternative ways would you recommend
IC
O) General
O1 In your readings research has been described as choices among conflicting goals
(desiderata) For instance when choosing among research strategies a researcher
must choose among the desiderata of precision realism and generalizability The
trade-offs among desiderata occur for all aspects of research that is for the selection
of theories the treatment of independent variables research strategies the selection
of the problem to study rules of evidence for determining the meaningfulness of a
research finding and even the frameworks that describe the research process
Discuss what you see as the major trade-offs for each of the following aspects of
research That is discuss what you see as the major strengths and weaknesses
(advantages and disadvantages) of each aspect
a The trade-offs between internal and external validity
b The manipulation of the independent variable vs the observation of the
independent variable
c Basic vs applied research
3 DESIGNING A RESEARCH STUDY
A) General (Research Design)
3) Why is control so important in research design What are the different ways it can be
achieved (give a brief description of each control method) What are advantages and
disadvantages of each
A1 It has become almost a truism to note that the choice of methods influences theory
and questions data and conclusions (the causal direction might also be reversed)
Briefly discuss how the methods used have influenced research in any two of the
following areas leadership power and politics organization culture organization
justice Compare and contrast as possible Suggest some potentially fruitful
methodological directions for future work in these same topical areas and dont be
shy about reflecting on broader issues of how the field of organizational behavior
constructs its realities Lastly tie your discussion and reflections back to your own
future as a researcher what lessons or guidance do you derive from your
understanding of these issues
A2 Characterize as fully as possible what you see to be the methodological approach or
approaches in strategic management research Is there a dominant method or a wide
variety Discuss the reasons for the situation What are the advantages benefits etc
of the approach(es) in use What assumptions (ontological epistemological
ideological) do they embody Are current efforts ideal or at least adequate Are
there other approaches that could be useful If so how might researchers be
encouraged to use these as well If you see no advantage to more variety in
methodological approach support that point of view
A3 Describe a research question or area of interest to you and why you think it is not
only of interest but significance Using your understanding of research methodology
describe two ways of pursing the question that are as divergent on as many
dimensions as you can imagine Describe the advantages and disadvantages of each
approach How strong a link or fit is there between a research question and a
method
A4 In his 1957 article entitled The two disciplines of scientific psychology Cronbach
discussed the assumptions goals and methods used in experimental methods and
correlational methods in psychology
a According to Cronbach what is the main difference between the two disciplines
b Discuss the strength and weaknesses of each discipline
c What if anything could be done to improve the situation
B) Designing a Research Study
B1 Cook and Campbell describe the experiment as the research design with the
greatest methodological rigor However given the constraints present in most
organizations I-O Psychologists cannot often conduct experiments in applied
settings and must settle for techniques with less control than experiments
Describe a study to investigate the relationship between participation in a
supervisor training program and work performance which could realistically be
conducted in an organization If an experiment is not possible describe how you
would go about maximizing your ability to draw valid conclusions from your
design
B2 The XYZ Co has recently developed a sexual harassment web-based training
program The developers claim the program will cut training time and costs and
will be as effective or more effective than classroom-based sessions They
believe that this will be due to the increased availability of the program and the
ability for participants to review program material on demand Before the XYZ
Co developers launch this product they want you to determine if their claims
have merit Explain how you would design a study for this purpose
B3 Research suggests that demographic diversity improves group creativity but
reduces group efficiency Some argue that demographic diversity is just a proxy
for value and experience diversity and that demographic diversity on its own is
meaningless Design a test to settle this argument
TH
B4 E-mail has become a common form of communication in organizations and is
used for both formal and informal communication Because it has become so
IC
popular some people complain that the frequent use of e-mail leads to
miscommunication because they receive communications in e-mail that should
be accomplished through face-to-face or telephone conversations where there is
an opportunity for interaction You are interested in looking at this
phenomenon You are most interested in describing how e-mail is used for both
formal and informal communication and in examining the effect of the e-mail
use on organizational communication effectiveness Design empirical research
to address those issues
Describe your study in detail thoroughly explaining the research design
sampling plan data collection procedures ethical issues and proposed data
analysis for your research design Be sure to discuss the internal and external
validity of your research Which validity threats are ruled out and which
remain
REMEMBER Be thorough Your research design should demonstrate that you
are a competent researcher who is knowledgeable about the proposed research
methodology or methodologies Therefore be sure that you carefully describe
and give technical explanations for each component of your research
B5 Choose a specific situation involving employee selection eg artists for an
advertising agency (a) What strategy would you use in selecting the selection
measures (b) How would you combine the measures eg which measures
would you combine in a compensatory manner and which is a noncompensatory
manner (c) How would you assume test fairness defining various measures of
the term (d) How would you make final selections (e) How would you
validate your procedure (f) What considerations would enter in if your
company were too small to provide validation data (g) What difference would
it make if you were developing a procedure for deciding whether trainees

but do not limit yourself to statistical issues
B6 There is evidence in the marketing literature of a non-monotonic relationship
between the expectations that customers have for retail service and their
eventual level of satisfaction with that service That is as a customers
expectations for service increase so does their eventual service satisfaction --
up to a point After that point the greater the expectations the lower the
eventual satisfaction Develop a hypothesis that includes a moderator variable
that might account for this evidence Give some reasonable rationale for it State
your hypothesis verbally as an equation as a directed graph (circle amp arrow
diagram) and as an X-Y function chart Discuss how it would or would not be
possible or useful to test your hypothesis via a laboratory experiment In your
discussion cover how and why a researcher could (not) manipulate the
independent constructs involved (mode X) whether or not random assignment
to conditions (mode R) is possible (including how may conditions would be
necessary) which alternative constructs could or could not be controlled (mode
K) and which constructs should be measured (mode Y)
B7 Assume you are the chairperson of a committee that must evaluate
undergraduate programs at your university Your task as chairperson is to
devise an approach (a design a research strategy a set of measures) that will
allow you to evaluate undergraduate programs Make sure that your approach
can be used in the future and at other comparable universities When developing
your plan be sure to address at least the following issues
a the type of design you would select Compare and contrast the selected design
with another possible design
b the type of research strategy you would select Compare and contrast with
another possible strategies
c discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
B8 Assume you are an organizational research design expert assigned to the
Strategic Planning Department of a large multi-national manufacturing firm
The Department has developed a new PC-based software package called
STRATPACK The software (and a one-week training course to learn how to
use it) is intended to improve the long-range planning ability of middle and
upper-level managers
Your job as research design expert is to devise research (a design a research
strategy a set of measures) that will allow you to evaluate the effectiveness of
the STRATPACK program Describe a research design for evaluating the
program Make sure that your research approach can be used in the future and at
all sites in the company When developing your plan be sure to address at least
the following issues

least internal external and construct validity
B9 Assume you are a consultant hired to evaluate the effectiveness of an industrial
safety program undertaken by a large manufacturing organization The safety
program is a behavioral one that provides rewards such as monetary bonuses or
extra paid vacation days for safety behaviors in terms of accident-free days
weeks etc Your task is to devise an approach (a research strategy a design a
set of measures and a general analysis strategy) that will allow you to evaluate
the safety program Because of the potential for the influence of many
extraneous variables on any safety program it is difficult to design research a
single cross-sectional study than can evaluate the impact of a single safety
program How would you design a study to evaluate the impact of the safety
program When developing your plan be sure to address at least the following
issues
a the type of research strategy you would select Compare and contrast with
another possible strategies

B10 One of the most important areas of research is forecasting of human resources
needs based on strategic positions of organizations For example NY State must
carefully forecast its human resources needs as it proceeds with significant lay-
offs of state employees Future human resources needs are generally evaluated
by either statistical ie regression or simulation or clinical judgment i e
supervisors judgments methods
a Design a single study that addresses the empirical question of whether
statistical or judgmental methods are better for forecasting human resources
needs You may discuss a program of research but please be quite specific in
your description of the first study
b What are the critical methodological issues in doing this kind of research
c What are the critical applied (or practical) issues in doing this research
d Are the issues in b and c related
B11 In the past decade computinginformation technology has changed many
aspects of organizational life For example the technology can make increased
decentralization possible by improving communication between central offices
and field offices Computer networks and word processors can enhance group
empowerment by making it possible for team members to create and edit
written group products quickly even if the individuals are at different locations
Some have argued that computinginformation technology will foster the
paperless productive office nevertheless others argue that the technology only
increases paper and reduces office productivity You are applying to the
National Science Foundation for a grant to conduct research that examines the
impact of computing information technology on organizational decision
processes The NSF application procedure imposes five basic requirements that
your research design must fulfill in order to receive funding Note A very
significant factor affecting NSF grant decisions is a clear demonstration that the
researcher is knowledgeable about the research methodology used Write your
response to each of the following five grant requirements Be sure not only to
respond to the requirement but also to demonstrate your research
competence
1You must design a study that uses two different methods
(interviewobservation survey experiment or quasi-experiment) Describe your
two methods in detail and provide a rationale for the key elements (eg
sampling data collection proposed analysis) of your methods Be sure to
discuss and evaluate the internal and external validity of both methods
2 As part of your research design you must select a conceptual (latent) variable
central to your proposal (use centralization of decision making as your
variable) and describe how you will develop your own measure (You may not
simply use off the shelf instruments)
3 You must describe how you will test for the reliability of the measure
(centralization of decision making) you developed in step 2 The NSF insists
that you describe how you will evaluate both the temporal stability and the
internal consistency of your measure Be sure to discuss what temporal stability
and internal reliability mean and how they are related
4You must describe how you will assess the validity of the measure
(centralization of decision making) you developed in step 2
5 NSF requires a brief statement and defense of the philosophy of science
underlying your research Discuss your position and show how your research
design is consistent with your philosophy
B12 Many organizations in the United States economy have installed some form of
Empowered Teams as an alternative or supplement to traditional bureaucratic
structure Preliminary evidence of the effectiveness of empowered teams
however is mixed--some organizations have claimed success and others have
reported failures The evidence however is predominantly anecdotal--written
for trade magazines by the organizations themselves There are few rigorous
empirical studies assessing the effectiveness of empowered or self-managed
teams You are applying to the United States Department of Labor (USDOL) for
a grant to conduct research that examines the effectiveness of empowered
teams The application procedure of the USDOL imposes three requirements
that your research design must fulfill in order to receive funding Write your
response to each of the three grant requirements The importance of each section
is implied by the evaluation points allocated by the USDOL to each of the three
requirements given in parentheses
1 (50 points) Your study design for assessing Empowered Team effectiveness
must use two different methods (interview observation archival analysis
survey simulation experiment or quasi-experiment) Describe in detail and
thoroughly explain the sampling plan instrumentation data collection
procedures and proposed data analyses for both methods Be sure to discuss the
internal and external validity of both methods and how the two methods
complement one another
2 (30 points) As part of your research design you must select one conceptual
(latent) variable central to your proposal and describe how you will develop
your own operationalization of the measure (You may not simply use off the
shelf instruments) Use the concept of group morale to demonstrate your
operationalization methodology Be sure to explain very explicitly to the
USDOL how you will assess the validity and reliability of the group morale
measure you are developing
3 (20 points) The USDOL traditionally has funded research conducted only
within the general paradigm of logical positivism but now is more open to other
research paradigms as well Your grant proposal must provide a statement and
defense of the explicit philosophy of science underlying your research Describe
your philosophy of science and show how your research design is consistent
with your philosophy
REMEMBER Be thorough You not only must design effective research but
you also must demonstrate to the USDOL that you are a competent researcher
It is absolutely vital to the USDOL that the principal researcher is
knowledgeable about the proposed research methodologies Therefore be sure
that you always carefully describe and give technical explanations for each
component of your research design and explain all technical terms (eg
Cronbach alpha KR-20 Likert scale)
B13 Assume that you are working as part of a research team that is responding to a
RFP (Request for Proposals) from a funding agency for research on work
socialization and newcomer adjustment The RFP calls for rigorous field
research that tests the effectiveness of theory-based interventions aimed at
facilitating the adjustment of new organizational members to complex andor
stressful work conditions The major goal of your teams research is to test the
effectiveness of a self-regulation intervention which trains newcomers to
identify and use relevant social information and cues to regulate work behavior
Your group hypothesizes that self-regulation training will be more effective
than other common treatments or interventions (eg realistic job previews
institutionalized socialization tactics)
You have been included in the team because of your methodological expertise
Your role is to design a rigorous field experiment or quasi-experiment to test he
effectiveness of the self-regulation training program REMEMBER THE
MAJOR CRITERION FOR FUNDING IS THE RIGOR OF THE RESEARCH
DESIGN Design a field study to include in the grant proposal Your proposal
should contain the following two sections
1 Study Design Construct and describe in detail an experimental or quasi-
experimental design to test the effectiveness of your intervention Describe in
detail the experimental groups (including how they will be constructed) the
research setting the sampling plan for study participants the treatment
manipulation and the data collection procedures Also indicate any control or
nuisance variables that may be measured
After describing the procedures write a justification of the design What threats
to validity does it rule out or limit and what threats to validity remain
II Measurement Describe the steps you would take to achieve valid and
reliable measure of the latent (conceptual) variable worker adjustment Your
team feels that as part of the proposal you must develop an original
operationalization of adjustment (thus you cannot simply use existing off the
shelf measures) Indicate in adequate detail how you would operationalize the
measure and indicate how you would demonstrate reliability and validity
B14 In describing their notion of the collective mind Karl E Weick and Karlene H
Roberts note Our focus is at once on individuals and the collective since only
individuals can contribute to a collective mind but a collective mind is distinct
from an individual because it inheres in the pattern of interrelated activities
among many people (p 360) Collective mind is not indexed by within-group
similarity of attitudes ideas or activities A collective mind is one in which
many people or many groups integrate their different attitudes ideas and
activities heedfully As Weick and Roberts note People act heedfully when
they act more or less carefully critically consistently purposefully attentively
studiously vigilantly conscientiously pertinaciously (p 361)
The idea of the collective mind as heedful interrelating is developed in the
following excerpt When people make efforts to interrelate these efforts can
range from heedful to heedless The more heed reflected in a pattern of
interrelations the more developed the collective mind and the greater the
capability to comprehend unexpected events that evolve rapidly in unexpected
ways When we say that a collective mind comprehends unexpected events we
mean that heedful interrelating connects sufficient know-how to meet situational
demands For organizations concerned with reliability those developments
often consist of unexpected non-sequential interaction (p366)
An example of heedful interrelating occurs as a pilot lands herhis aircraft on the
deck of an aircraft carrier The pilot does not actually land She is recovered
A recovery is an interrelated set of activities among air traffic controllers
landing signal officers the control tower navigators deck hands the helmsman
driving the ship etc These activities can be interrelated more or less heedfully
depending on the care with which the different units contribute represent the
situation and subordinate their activities to the single purpose of successful
recovery (p 363)
You are to design a two-part study
Part I You are to design a measurement study which assesses heedful
interrelating (ie collective mind) with a quantitative measure in a replication
of an aircraft carrier flight deck or other situation of your choosing Describe
your research strategies including operationalization of the variable selection of
the sample subjects data collection data analysis and so on for the purpose of
developing a measure of heedful interrelating
Part II Using the measurement tool developed in Part I and any other tools as
needed describe how you would design a study which would compare heedful
interrelating across organizations Choose at least one macro-organizational
variable (eg technology environment) as your basis of comparison Here you
must describe how you would make your selection of organizations to be
compared your data collection procedure data analysis and so on
B15 Many organizations in the United States have installed cross-functional teams to
counteract the silo mentality of traditional bureaucratic structure Preliminary
evidence of the effectiveness of cross-functional teams however is mixed --
some organizations have claimed success and others have reported failures The
evidence moreover is predominantly anecdotal--written for trade magazines by
the organizations themselves Since there have been few rigorous empirical
field studies assessing the effectiveness of cross functional teams the National
Science Foundation has decided to fund research on the topic
Assume that you are submitting a research proposal to NSF for a grant to
research the effectiveness of cross-functional teams Describe in detail and
thoroughly explain the research design sampling plan data collection
procedures ethical issues and proposed data analysis for your research design
Be sure to discuss the internal and external validity of your research Which
validity threats are ruled out and which remain NSF also requires that you
provide a statement and defense of the explicit philosophy of science underlying
your research Describe your philosophy of science and discuss how your
research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but
you must also demonstrate to NSF that you are a competent researcher It is
absolutely vital to NSF that the principal researcher (you) is knowledgeable
about the proposed research methodologies Therefore be sure that you always
carefully describe and give technical explanations for each component of your
research design and explain all technical terms (eg Cronbach alpha KR-20
Likert scale)
B16 Assume that you are submitting a research proposal to the Department of
Commerce (DoC) for a grant to research the effectiveness of virtual work teams
A virtual work team is a leaderless collection of individuals who are
geographically separate from one another and share their expertise using
internet media such as a listserver or Lotus notes The DoC requires that the
researcher use both qualitative and quantitative methods to gather data Describe
in detail and thoroughly explain the research design sampling plan data
collection procedures ethical issues and proposed data analysis for your
research design Be sure to discuss the internal and external validity of your
research Which validity threats are ruled out and which remain The DoC also
requires that you provide a statement and defense of the explicit philosophy of
science underlying your research Describe your philosophy of science and
discuss how your research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but
you must also demonstrate to DoC that you are a competent researcher It is
absolutely vital to DoC that the principal investigator (you) is knowledgeable
about the proposed research methodologies Therefore be sure that you always
carefully describe and give technical explanations for each component of your
research

that improves upon the key validity (or validities)
5 MEASUREMENT
A) Measurement Terms
A1 There are four levels of measurement rigor in management research Discuss each
one What properties do measurements at each level have (ie how much
information do the numbers from each level of measurement convey) How can the
numbers be changed (transformed) and still retain the properties of their
measurement level Pick one construct from a favorite research domain and give an
example of an operationalization of that construct at each of the four levels of
measurement rigor (provide arguments about why you think those examples reflect
each level) Lastly treat each examplelevel as a dependent variable in some
statistical analysis Given an example of a statistical technique appropriate for
analyzing data at that level of measurement rigor
A2 Define (and discuss important features or issues concerning) the following
constructs measurement (Define any six terms)
1 Construct validity 6 Item analysis
2 Likert scaling 7 Semantic differential
3 Cronbachs alpha 8 True score
4 Unobtrusive (trace) measurement 9 Generalizability theory
5 Interval scale 10 Criterion-related validity
11 Sociometric choice measures
B) Operationalization
B1 a) You are conducting a study which requires you to measure Hong Kong real
estate agents self-assessment of performance Since there is no existing
measurement available you have to develop the instrument by yourself
Describe how you would develop the measurement assuming that you have no
idea of how many dimension the construct has
b) Suppose you have developed an instrument consists of 20 questions
measuring 4 dimensions (5 items per dimension) from (a) You collected data
from another 300 real estate agents to validate your instrument Explain how
TH
you would use structural equations model (SEM) to examine the reliability and
validity of the instrument What are other concerns about reliability and validity
that are not addressed by this approach
B2 The research and business world have been fascinated with the concept of
organizational culture However operationalizing this construct has been a
difficult task Discuss the ways in which the construct has been operationalized
(eg technique static v dynamic sample selection generalizability) Critically
analyze each of these methodologies Then choose a methodology you would
use to examine organizational culture and defend your choice Describe how
you would study culture and what more would be known about culture as a
result of your study
B3 Suppose you are setting out to develop a new measure of a construct You want
this measure to be used in survey research and you want to establish its validity
and reliability Your goal is to have at the end of the process a measure that is
defensible and likely to be widely accepted by other researchers studying that
construct What steps would you take to conduct such a program of research
For each step explain the purpose of that step explain why that step is
important explain what methods and statistical procedures you would employ at
each step and explain what evidence you would hope to gather at each step
B4 Assume you are interested in constructing a new measure of (fill in with a
relevant variable from your field) Detail the major concerns that need to be
addressed and the steps that need to be taken in working toward validating this
new measure
B5 Assume that you recently read an article on workplace violence which you
found very interesting The authors argued that one of the predictors of
workplace violence was a construct called propensity to be violent and used a
one-item measure as follows How likely are you to become violent when
provoked You had serious doubts about the authors measure and decided to
develop your own
(a) How would you go about developing items to measure propensity to be
violent
(b) How would you determine whether the instrument was reliable
How would you determine whether the instrument was valid
B6 A concern in organizations is retirement of baby boomers within the next 5 -
10 years This concern is focused on the loss of older employees with skills
critical to the core business functions of organizations In order to continue to
have employees with those critical skills it seems necessary to retrain some
older workers However past practice in most organizations has been not to
retrain older workers for a variety of reasons mostly financial A researcher
working for the Human Resources Department of a large corporation - 13500
employees in 12 different plant locations - hypothesizes that the major reason
for not retraining older workers is ingrained in the culture of the corporation
IC
The researcher feels that older workers are not as highly valued as younger
workers in terms of their potential usefulness after retraining The researcher
searched the literature but found nothing in the existing literature to measure
the cultural value construct What should the researcher do to establish a reliable
and valid self-administered paper and pencil measure of this construct namely
the value of retraining older workers
a Please describe and explain the steps in temporal order that the researcher
must follow to develop a measure
b How would you evaluate the measure based on the technical requirements of
reliable and valid measurement as well as any practical issues in using the
measure considering the size of the employee population
B7 Assume that you are going to conduct empirical research to assess the role that
the complexity of an organizations manufacturing technology plays in
determining the level of centrality of decision making in the organization
Describe and justify the steps you might follow to develop an operationalization
of the concept of technological complexity What standards would you use to
determine if your operationalization is valid
B8 Organizational researchers have several strategies available to them for
gathering information (eg self-report measures archival measures direct
observation and trace measures) Assume that you are going to conduct
empirical research to assess the role that the structure of the organization plays
in determining the level of organizational effectiveness Briefly review the
strengths and weaknesses of the basic strategies (that is self-report measures
archival measures direct observation and trace measures) for measuring
organizational effectiveness Next describe and justify the steps you would
take to develop an operationalization of the concept of organizational
effectiveness What standards and procedures would you use to determine if
your operationalization is valid
B9 One of the most important topics of recent research has been stress in the work
place One of the most important problems with understanding this literature is
the varying definitions and measurement of this construct Suppose you had
decided to investigate the relationship between stress at the work place and dual
career family happiness
a Since there are multiple ways to measure stress in the work place describe
two ways to do this Hint - avoid using two self-report measures
b Describe how you would decide on the best single measure In doing so
describe the steps you would take in evaluating your measure Be sure to define
your meaning of validity and reliability It is important that your measure have
all the necessary psychometric characteristics so that other scientist can trust the
results of your research
c Be certain that you answer the question Validity for what
d In order to understand the results of your study you need to compare your
measure of stress at work with other measures of this construct How would you
do that
B10 Assume that you have been hired by a national survey research company
Shash Inc to write items that will be used in a national survey of attitudes
toward capital punishment There are a number of criteria that can be used to
guide your item writing What are they Briefly describe five (5) such criteria
B11 Assume that you are going to conduct empirical research to determine the
impact of interpersonal trust on organizational decision making Describe and
justify the steps you might follow to develop an operationalization of the
interpersonal trust concept
B12 Assume that you are going to conduct empirical field research to assess the role
that employee empowerment plays in determining the level of organizational
commitment of employees Describe and justifyexplain the steps you would
follow to develop a valid and reliable operationalization of the concept of
employee empowerment
Explain the procedures and standards you would use to determine if your
operationalization is valid and reliable
How would you assess the construct validity of such a measure
Discuss issues concerning the level of observation of your measure and level of
analysis of the data
B13 Assume you are interested in developing a new scale to measure construct X
Further assume that you have used previous literature and your own conceptual
development to delineate 2 dimensions of X specifically XF1 and XF2
Describe the steps you would go through in developing testing and evaluating
this new scale With regard to testing and evaluating be sure to consider the
role of factor analysis (both exploratory and confirmatory) and item analysis
Also you will want to make sure that your new multidimensional scale shows
evidence of validity (several kinds) and reliability so be sure to examine these
issues and explain how specific information gathered from the above testing
contributes to these concerns
C) Reliability
4) What is reliability and why is it so important What are the different ways reliability can be
assessed and when is each appropriate
15) What does coefficient alpha assess What are the ways coefficient alpha can be increased
C1 Describe and discuss the concept of reliability and all of its various forms
including their assessment When is each form appropriate and what information
is provided by each index
C2 In establishing congruence between multiple measurements we often compute
indices of reliability andor indices of agreement These two types of indices
address very different questions Your task is to 1) Define reliability and
agreement 2) Explain when each is useful using examples in which one but not
the other is appropriate and 3) Briefly describe two reliability indices and two
agreement indices
C3 Explain reliability in terms of the classical test theory What are the
consequences of unreliable measures in hypothesis testing What are the factors
that may affect the reliability of a multi-item scale
IC
C4 Generalizability theory is used within IO psychology more often today
However most researchers continue to use Classical Test Theory
conceptualizations of error to determine reliability What are the implications of
using classical test theory versus generalizability theory to assess reliability
C5 In establishing congruence between measurements we often compute indices of
reliability andor agreement Define reliability and agreement Explain the
differences in reliability and agreement and describe under what conditions
assessing reliability is more appropriate and under what conditions assessing
agreement is more appropriate
C6 Define measurement reliability in terms of a specific measurement theory (eg
true test score theory domain sampling theory generalizability theory IRT)
Discuss the different approaches for estimating reliability and the contexts in
which each might be appropriate Use examples throughout
C7 What are the consequences of unreliability in a measure
C8 What are some of the conditions that might keep the internal consistency (eg
alpha) of a given measure low Is a low alpha always a sign of a problematic
measure
C9 Define reliability Name some methods of calculating reliability How well do
these methods map up with the definition of reliability What is the impact of the
number of test items and sample size on Chronbachs alpha and why would this
effect occur or not occur (Note Do NOT discuss inter-rater reliability)
C10 Schmidt and Hunter (1996) described several types of measures typically used in
organizational research and identified the type(s) of measurement error affecting
each of them in various situations For each measure below indicate the types of
error and sources of error that are most likely to affect it Then indicate what
could be done to reduce errors of measurement andor what can be done to
control for errors statistically
a Supervisor ratings of subordinates job performance
b Self-ratings of ones own job performance
c Self-reports of ones own job-related attitudes
d Sales figures for a salesperson (or production quantity for a production
worker)
d Aptitude tests taken as part of the hiring process
C11 Suppose you had conducted research on the relationship between organizational
commitment and rigidity of organizational structure in 200 firms Your measure
of rigidity was based on number of organizational authority levels and the degree
to which written organizational rules existed and defined role behaviors for
employees Thus an organization with a large number of organizational levels
and specific written policies defining appropriate role behaviors for employees
would score high on rigidity of organizational structure After analyzing your
data you find that there is a statistically significant negative correlation between
commitment and rigidity which is consistent with your hypothesis However the
reliabilities for your two measures are
(1) commitment = 23 (2) rigidity = 83
How should you interpret your results What could you do to fix this situation
Describe the specific steps (in order) you would follow to develop a more
reliable measure of commitment
C12 (a) Define the concept of reliability (of measures) in a clear concise and
accurate manner (b) Provide a formula that expresses the reliability of a measure
in terms of two components of variance ie total variance and the error
variance
D) Multi-level Assessment
D1 One of the major challenges for group-level research is the issue of aggregation of
individual data to the group level
(a) Under what conditions (eg types of data number of raters) should the various
interrater agreement and reliability methods be used (Rwg Kappa and Weighted
Kappa percent agreement average pairwise correlation ANOVA methods
(interclass correlation coefficient WABA)) What are the advantages and
disadvantages of each of the methods
(b) Explain the controversy between Frank Schmidt Larry James and others
regarding the differences between interrater agreement and interrater reliability
Who is right Do the differences matter in research practice
Defend your answers
(c) Review two articles from the organizational behavior literature that have had to
deal with aggregation issues Critique the methods the authors used to make
aggregation decisions
(d) Provide some advice to researchers regarding what they should do if interrater
agreement and reliability indices indicate that it is not legitimate to aggregate their
data
(e) Provide some ideas for avoiding the need to aggregate in group-level research
through creative research methods and measurement strategies
D2 Cross-levelmulti-level research is becoming more evident in the organizational
research literature This type of research raises many issues and presents many
challenges in terms of designing the research measuring variables and collecting
and analyzing the data Assume that you are interested in aggregating data (eg
from the individual to the group or from the firm to the industry) for one or more
variables What are the major issues you will need to deal with
D3 A researcher wants to measure organizational climate for continuous learning
Organizational climate is operationalized as a shared consensual aspect of the
organization -- the shared perception among employees that the organization values
and supports continuous learning Describe how you would measure organizational
climate in this case Specify (a) the level (ie individual group organization) at
which the construct exists (b) the level at which you would measure the construct
and (c) the procedures that you would use to establish that measurement is aligned
with theory (ie the construct validity of the measure)
E) General (Measurement)
E1 Studies in organizational behavior research often rely on single-item measures of
key constructs The use of single-item measures has long been criticized based
on the premise that single-item measures are unreliable However Wanous
(Wanous amp Hudy 2001 Wanous amp Reichers 1996 Wanous Reichers amp Hudy
1997) has recently argued that single-item measures can exhibit adequate
reliability Wanous based this conclusion on a procedure for estimating the
reliability of single-item measures using the classic formula for correction for
attenuation Subsequent studies have yielded mixed results regarding the
conclusions of Wanous (eg Loo amp Kells 1998 Nagy 2002) and the veracity
of the perspective advocated by Wanous remains in question Summarize and
assess the arguments for and against the use of single-item measures and
evaluate the procedure and evidence offered by Wanous regarding the reliability
of single-item measures Based on your assessment and evaluation develop
recommendations regarding the use of single-item measures in organizational
behavior research

E2 Ipsative measures have become prevalent in organizational behavior research
Ipsative measures ask respondents to answer questions relative to one another
such that the scores for all questions sum to the same constant for all respondents
Examples of ipsative measures include rankings Q-sorts and the allocation of a
fixed number of points (eg 100) across a set of response options Ipsative
measures may be contrasted with absolute measures which ask respondents to
answer questions independently from one another Absolute measures are
exemplified by rating scales using an interval or ratio numeric response format
The relative merits of ipsative and absolute measures have been debated for
decades (eg Cornwell amp Dunlap 1994 Hicks 1970 Johnson Wood amp
Blinkhorn 1988 Saville amp Wilson 1991 1992) yet the fundamental issues
underlying this debate have not been adequately addressed in organizational
behavior research For example measures of organizational culture and values
are often ipsative and some researchers advocate these measures over absolute
measures (eg Meglino amp Ravlin 1987 OReilly Chatman amp Caldwell 1991
Ravlin amp Meglino 1987 see also Rokeach amp Ball-Rokeach 1989) Review the
relative merits of absolute and ipsative measures Based on your review which
form of measurement is most appropriate and why Do your conclusions depend
on the construct being measured If so what types of constructs are best suited to
ipsative measures and what types are best suited to absolute measures Next
apply your conclusions to the measurement of culture and values in
organizations What specific arguments have been advanced in favor of ipsative
measures of culture and values How sound are these arguments Should ipsative
measures be used in the study of organizational culture and values If not how
can absolute measures of culture and values be developed that address the
concerns voiced by advocates of ipsative measures Provide a specific example
of the type of measure you would propose

E5 Suppose Roberta Von Eisenbrick is a researcher interested in the consequences of
AFFECTIVE CONFLICT (AC) in decision-making teams She gets access to a
variety of outcomes assessment committees at each of 87 different schools in
the Dallas Independent School District and gains permission to tape-record two
of their meetings (one in February and one in March) Such committees have
been formed to develop quantitative ways to track pursuit of school goals and
provide accountability to local and state governments These are often divisive
teams with heated meetings because what gets assessed is what usually gets
rewarded After both of these meetings the committee members each
fill out a short questionnaire that contains 20 Likert-type items measuring how
much AC occurred (eg People in our group often get angry with each other)
The individual scores are summed across items then averaged across team
members to come up with a group-level AC score for each of the 87 2
meetings The same procedures are followed for a 5-item measure of Group
Cohesiveness (GC) which is predicted to be reduced by higher levels of AC
Roberta also listens to every tape and from her expert judgment she rates each
groups meetings on the same 20 items Those 20 ratings are summed for each of
the 87 2 meetings Now Roberta is interested in evaluating her measure She
wants it to have excellent psychometric properties including reliability and
construct validity

it
c What is construct validity Discuss how the (un)reliability of the AC measure

D1 Moderation and mediation provide different ways to model third variable effects
(a) Please define both of these terms (b) Sketch a conceptual model to show how
each relates to main effects (c) Using variables of your choice please write
hypotheses to reflect both (d) Explain how each is tested analytically
D2 Discuss moderators and mediators Provide an example of how (1) a moderating
variable influences the relationship between the independent and dependent
variable and how (2) a mediating variable influences the relationship between
the independent and dependent variable Describe how you would test for both
moderation and mediation using regression
D3 Many theories in organizational research predict that the effects of one variable
on another are moderated by a third variable Such moderator effects are
typically tested by entering the product of two variables as a predictor after
controlling for the two variables that constitute the product Several researchers
have pointed out that this product is often highly correlated with the squares of
the two constituent variables and have suggested that moderating effects may be
tested after controlling not only for the two constituent variables but also their
squares (eg Cortina 1993 Ganzach 1998 Lubinski amp Humphreys 1990
MacCallum amp Mar 1995) Discuss the strengths and weaknesses of this
approach as compared to methods that use only the product term and its
constituent variables Conclude with recommendations as to when and under
what conditions organizational researchers should test moderator effects with the
squares of the constituent variables in the equation

D4 Assume you are interested in studying relationships amongst three variables X
Y and Z Your first hypothesis posits Z as a mediator of the relationship between
X and Y Your second hypothesis posits Z as a moderator of the relationship
between X and Y Draw the figures depicting each of these hypothesized
relationships and describe (make sure to write regression equations) how you
would test each of these hypotheses
D5 The amount of time and effort that the average person pours into his or her job
has risen steadily over the last two decades such that the average person now is
working one more week per year than the average person in the mid 1970s This
steady increase has fueled research interest in the construct of Job Burnout (JB)
which is an emotional and physical exhaustion associated with ones work
Organizational Stress (OS) the perception of greater demands than available
resources in ones work environment is thought to be one of the chief
antecedents of JB However time spent under OS is thought to make its affects
on JB accumulate or worsen Work Role Withdrawal (WRW) the avoidance of
responsibilities or the deliberate reduction of inputs to ones job is believed to be
the chief consequence of JB
a Formally state these ideas as verbal hypotheses as equations and as a complex
directed graph (circle amp arrow diagram)
b Conceptually what is a mediator Define the term and identify the mediator in
your hypotheses in (a) What elements or steps in a study design (not statistics)
that would be helpful for detecting the mediating relationship that was proposed

subdomains of management Further demonstrate your understanding of
moderator variables by picking which variable in (a) is the moderator Show the
moderating relationship in an X-Y (or multi-layered) chart Again what elements
or steps in a study design (not statistics) would be helpful for detecting the
moderating effect implied above

recommendations You conduct a well-designed controlled study (details are unimportant) and discover students who use the new book perform 10 better on a standardized subject
matter exam than those using the old book (p = 027) Both books are readily availabe their prices are almost identical and both are equally acceptable to the instructors What is your recommendation to the chair
F1 Attached is the beginning of an article Your task is to write the results section by
1 making up and reporting plausible descriptive statistics that will help the
reader understand the results of the statistical tests you report and the nature of your
sample (Hint this can be presented in the form of a table)
2 describing and defending your choice of appropriate statistical tests of the
hypotheses and the steps that you would go through in carrying out these tests
3 making up and reporting results of these tests that are consistent with your
descriptive statistics and with any information in the rest of the article about the
results found (Hint this can be presented in the form of a table)
4 describing how well these results provide support for the hypotheses You
may want to note any relevant threats to validity here
Be sure to state any assumptions you make
F2 Assume that the Personnel Manager of a local firm Ms B dFlandres hired you to
analyze some data that her assistants had collected over the past several years The
data consist of (a) job performance ratings that were made in June of 1990 and (b)
scores on 25 predictor variables (eg measures of education job experience job
tenure job aptitude personality) that were measured when the individuals were hired
(between April 1987 and May 1988) She had data from only the 110 subjects (60
males and 50 females) who were hired during the period and were still employed by
the firm One objective of your analysis (analyses) is to determine how well the
performance criterion can be predicted by the predictors What strategy would you
use in analyzing the data Describeexplain (b) Is sample size an issue for your
analyses Explain If it is what will you do to deal with problems stemming from
sample size Assume that no additional data can be collected at this time (c) Some
preliminary analyses that you do reveal that five of the predictor variables correlate
(zero-order basis) about 75 with one another Will this influence the analyses that
you use Will it influence the validity of conclusions derived from your proposed
analyses (d) Ms dFlandres is interested in knowing if the predictor variables are
equally effective in predicting the job success of males and females What analysis
or analyses would you do to deal with this issue
F3 Assume that you have been provided with data on 12 conceptually distinct variables
that are moderately correlated with one another at the empirical level The data are
from students in four different college majors ie astronomy (A) biology (B)
criminology (C) and demography (D) The 12 measured variables fall into the
general categories of mental health (tension emotional withdrawal hallucinations
guilt feelings blunted affect and suspiciousness) and job satisfaction (work itself
supervision co-workers pay promotion prospects and working conditions) Your
task is to determine if the individuals in the four college majors differ from one
another on the 12 measured variables
(a) What statistical technique(s) would you use to test for group differences
Explain Be specific about the procedures(s) that you would use
(b) What statistical estimate would you use to estimate the extent to which the
groups differ from one another Be specific
F4 The following statistical table published in a recent issue of Work amp Occupations
was taken from an article discussing variables influencing resistance and citizenship
behaviors in the workplace Resistance behaviors include playing dumb withholding
effort work avoidance subverting particular managers and sabotage Citizenship
behaviors include cooperation engaging in peer training use of insider knowledge to
facilitate production commitment to organizational goals giving extra effort freely
Both measures are global constructs aggregated to the interval level and
standardized
The table reports the results of a series of ordinary least squares regression equations
with standardized coefficients Explain the meaning of the statistics presented What
do these statistics tell us generally about the relationship between resistance
behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows
Anomie Index -standardized interval level measure tapping multiple dimensions
The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)
F5 Researchers collected data from a sample of 350 companies on the following
variables
size (measured as number of employees)
Business Strategy (a nominal variable with 2 response options low-cost provider or
differentiator)
HR Strategy (a nominal variable with 2 response categories High commitment or
low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

What is the role of theory in the two factor analyses
IC
O2 Compare and contrast Exploratory Factor Analysis (EFA) with Confirmatory TH
Factor Analysis (CFA) Put more emphasis on their theoretical basis
assumptions usage and limitations
O3 How do exploratory and confirmatory factor analysis differ What are the
advantages and disadvantages of each
O4 Describe the differences between exploratory factor analysis (EFA) and
confirmatory factor analysis (CFA) When would you use one verses another
Are there ways to use EFA in a confirmatory way Can you use CFA in an
exploratory way Also describe the difference in principal components analysis
(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression
O6 The basic factor analysis model can be represented by the matrix algebraic
equation A B = C
(1) What do each of these matrices represent Be specific as to the type of
information in each matrix and its purpose
(2) For what purpose do researchers use factor analysis Explain In the process
provide a very brief description of a study for which factor analysis would be a
useful data analytic technique
O7 Factor analysis is an important statistical technique in organizational research
Describe factor analysis as an analytical tool including the following issues
a the reasons for using factor analysis
b the type of data necessary for using the technique appropriately
c the type of quantitative output that results from applying the technique
d how a researcher would use the output in his or her research
e how confirmatory factor analysis is different from exploratory
f the important issues and problems in using the technique
P) Structural Equation Models
P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

parameter estimate bias in structural equation modeling Structural Equation

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)
Please comment on these restrictions versus access argument Which side do you
take
What are the strengths of SEM Give some examples
What are the weaknesses of SEM Give some examples

aware there are numerous typesforms of validity (eg internal and external validity
construct validity statistical conclusion validity) These types of validity address
different aspects of the research process For this question please address the following
issues
a What is the meaning of the four major forms of validity (ie internal and external
validity construct validity statistical conclusion validity)
b Should there be a priority among these forms of validity If yes why If no why not
c Does the concept of validity vary across research traditions (ie experimental vs
observational research) If yes why If no why not
J10 External validity has received considerable attention in the social and behavioral
sciences Some researchers argue we are too concerned with the external validity of our
findings while other researchers argue that we are too unconcerned with external
validity Several points of view have been developed to explain what is external
validity When answering this question please be sure to address at least the following
issues
a Compare and contrast alternative conceptualizations of external validity
b Some researchers have argued that the role of external validity is invariant across
research traditions (ie experimental vs observational research) Defend the
perspective that the role external validity is invariant across these two research
traditions In addition present the weaknesses of this perspective
J11 In designing a research study researchers must consider trade-offs between internal and
external validity Explain what is meant by internal validity and external validity What
is the nature of these trade-offs How would you evaluatedetermine which is more
important internal or external validity for a particular study Why is this such an
important issue in organizational studies
J12 A researcher conducted a quasi-experiment to test the effects of participative decision
making (PDM) on job attitudes of employees Employees from different departments in
a large organization were assigned to either a treatment group (PDM implemented) or a
control group (no PDM) Random assignment was not possible because of work
schedules coordination of tasks etc Thus the design can be considered an untreated
control group design with pretest and posttest and is represented as follows (where
O=observation X = treatment)

What is (are) the major threat(s) to internal validity B if any B for this type of design
given these results What steps can be taken to assess the extent of this (these)
threat(s)
K) Data Collection Methods
14) Describe the various methods of data collection (eg survey interview observation etc)
available to a social scientist What are the advantages and disadvantages of each relative to
each other
K1 Within micro organizational research much criticism has been raised concerning
the reliance on self-report survey data What potential problems does self-report
survey research raise How big of a problem do you think this is
K2 There are a number of methods for collecting data (eg survey interview archival
etc) that are available to a social scientistorganizational researcher Discuss each in
terms of their strengths and weaknesses both on their own and in comparison to one
another
K3 Pick an important construct in your favorite area of management research for which
there is some controversy about how it should be measured or operationalized (eg
environmental munificence or growth need strength) Give the prevailing verbal
definition of the construct and analyze the measurement controversy from two
broad angles First discuss how the controversy may or may not stem from claims
about how one measure is better or worse than another because it (or the other) is an
(a) archival record (b) direct observation (c) social report or (d) self-report That is
what are the relative strengths and weaknesses of each of these types of
measurement for the construct youre discussing Second discuss the construct
validity of the most commonly used measure(s) of this construct To answer this
second part you need to discuss just what construct validity is and how it can or
cannot be demonstrated In the situation you describe what could be done to
demonstrate or improve the construct validity of existing measures
K4 Interviewing in some form has been the workhorse for data collection in a variety
of research traditions positivistquantitative ethnographic feministpost-modernist
and increasingly historical research While each tradition elicits information from
respondents the goals and processes involved in interviewing vary considerably
across research traditions Discuss the purposes of the interview the relationship
between data and theory the roles assumed by the interviewer and the respondent
and the relevant criteria for assessing the validity and reliability of the information
obtained In addition compare and contrast the use of the interview as a data
collection method in the positivistquantitative tradition with its use in one of the
alternative traditions
L) Common Method Variance
L1 Many of us have had concerns about the reviews of our survey research which
suggest that data analyses of surveys are biased because of common method
variance effects of individual differences such as negative mood negative
affectivity and social desirability and the reliability and validity of the constructs
we are attempting to measure Define how these problems affect a research issue in
organizational behavior and the steps that might be taken to minimize such potential
criticisms of papers based on analyses of self-reported data through survey
instruments
L2 In a series of papers by Spector (1994) Schmitt (1994) and Howard (1994)
published in the Journal of Organizational Behavior arguments were provided for
and against the use of self-report questionnaire measures One of the issues
discussed that could limit conclusions drawn from relationships observed using self-
report measures was method variance What is meant by method variance what are
its sources and what impact is it expected to have on research findings
M) Sampling
M1 The manufacturing census samples all plants of 250 employees or more For
plants of 5-249 employees it takes a size proportional sample Plants of 1-4
employees are not sampled What challenges does this sampling method provide
to researchers What could you do to account for these problems if you were
TH
studying organizational (not plant) growth
M2 New York State has approximately 250000 employees in over 70 state agencies
commissions and boards ranging in size from approximately 50 to over 5000
employees Assume that you wanted to draw a representative sample of 1000
employees Describe two ways that you could draw such a sample and briefly
describe the advantages and disadvantages of each of these sampling approaches
IC
M3 The director of a national non-profit agency with approximately 10000
employees located primarily in regional offices in each of the 50 states the
United States has approached you and asked you to develop a study
(organizational survey) of organizational culture within the agency The agency
is about to embark on a variety of change initiatives including developing team
structures and the study is meant to examine various elements of organizational
culture that are potential barriers to change The director has indicated that he
would like to have the data analyzed at both the individual and office level of
analysis Because of funding limitations the agency will only be able to send the
survey to 1000 employees The director has indicated that there are three ways
of sorting employees all employees listed alphabetically all employees listed
alphabetically by state and all employees listed alphabetically by region (there
are between five and ten regions per state) Given these three ways of sorting
employees describe at least three different sampling approaches and the
advantages and disadvantages of each
M4 In your role as Teacher of Organizational Studies you are asked to prepare a
tutorial for beginning doctoral students on sampling design Assume that this
tutorial is part of a basic class in research design and that students in this class
have had a basic statistics course up to and including multiple regression Your
tutorial should focus on briefly defining and explaining the differences between
probability and non-probability samples You should make sure to present and
describe several types of probability samples (eg random systematic
stratified etc) and non-probability samples (eg convenience snow-ball quota
etc) and discuss general principles for when to use a probability vs a non-
probability sampling design For each sampling design you should also provide
at least one clear example of a situation where this type of sampling design is
appropriate
N) Cross-Cultural Research
N1 Discuss the problems in conducting cross-culturalnational comparison in terms
of (1) conceptualization and (2) research design and data collection
Define the three levels of measurement invariance How would the problems that
you have identified in part (a) affect measurement invariance How would you
examine measurement invariance by confirmatory factor analysis
TH
N2 Explain why using national boundaries as independent variable in cross-cultural
studies may not be appropriate in terms of theory and research methods What
alternative ways would you recommend
IC
O) General
O1 In your readings research has been described as choices among conflicting goals
(desiderata) For instance when choosing among research strategies a researcher
must choose among the desiderata of precision realism and generalizability The
trade-offs among desiderata occur for all aspects of research that is for the selection
of theories the treatment of independent variables research strategies the selection
of the problem to study rules of evidence for determining the meaningfulness of a
research finding and even the frameworks that describe the research process
Discuss what you see as the major trade-offs for each of the following aspects of
research That is discuss what you see as the major strengths and weaknesses
(advantages and disadvantages) of each aspect
a The trade-offs between internal and external validity
b The manipulation of the independent variable vs the observation of the
independent variable
c Basic vs applied research
3 DESIGNING A RESEARCH STUDY
A) General (Research Design)
3) Why is control so important in research design What are the different ways it can be
achieved (give a brief description of each control method) What are advantages and
disadvantages of each
A1 It has become almost a truism to note that the choice of methods influences theory
and questions data and conclusions (the causal direction might also be reversed)
Briefly discuss how the methods used have influenced research in any two of the
following areas leadership power and politics organization culture organization
justice Compare and contrast as possible Suggest some potentially fruitful
methodological directions for future work in these same topical areas and dont be
shy about reflecting on broader issues of how the field of organizational behavior
constructs its realities Lastly tie your discussion and reflections back to your own
future as a researcher what lessons or guidance do you derive from your
understanding of these issues
A2 Characterize as fully as possible what you see to be the methodological approach or
approaches in strategic management research Is there a dominant method or a wide
variety Discuss the reasons for the situation What are the advantages benefits etc
of the approach(es) in use What assumptions (ontological epistemological
ideological) do they embody Are current efforts ideal or at least adequate Are
there other approaches that could be useful If so how might researchers be
encouraged to use these as well If you see no advantage to more variety in
methodological approach support that point of view
A3 Describe a research question or area of interest to you and why you think it is not
only of interest but significance Using your understanding of research methodology
describe two ways of pursing the question that are as divergent on as many
dimensions as you can imagine Describe the advantages and disadvantages of each
approach How strong a link or fit is there between a research question and a
method
A4 In his 1957 article entitled The two disciplines of scientific psychology Cronbach
discussed the assumptions goals and methods used in experimental methods and
correlational methods in psychology
a According to Cronbach what is the main difference between the two disciplines
b Discuss the strength and weaknesses of each discipline
c What if anything could be done to improve the situation
B) Designing a Research Study
B1 Cook and Campbell describe the experiment as the research design with the
greatest methodological rigor However given the constraints present in most
organizations I-O Psychologists cannot often conduct experiments in applied
settings and must settle for techniques with less control than experiments
Describe a study to investigate the relationship between participation in a
supervisor training program and work performance which could realistically be
conducted in an organization If an experiment is not possible describe how you
would go about maximizing your ability to draw valid conclusions from your
design
B2 The XYZ Co has recently developed a sexual harassment web-based training
program The developers claim the program will cut training time and costs and
will be as effective or more effective than classroom-based sessions They
believe that this will be due to the increased availability of the program and the
ability for participants to review program material on demand Before the XYZ
Co developers launch this product they want you to determine if their claims
have merit Explain how you would design a study for this purpose
B3 Research suggests that demographic diversity improves group creativity but
reduces group efficiency Some argue that demographic diversity is just a proxy
for value and experience diversity and that demographic diversity on its own is
meaningless Design a test to settle this argument
TH
B4 E-mail has become a common form of communication in organizations and is
used for both formal and informal communication Because it has become so
IC
popular some people complain that the frequent use of e-mail leads to
miscommunication because they receive communications in e-mail that should
be accomplished through face-to-face or telephone conversations where there is
an opportunity for interaction You are interested in looking at this
phenomenon You are most interested in describing how e-mail is used for both
formal and informal communication and in examining the effect of the e-mail
use on organizational communication effectiveness Design empirical research
to address those issues
Describe your study in detail thoroughly explaining the research design
sampling plan data collection procedures ethical issues and proposed data
analysis for your research design Be sure to discuss the internal and external
validity of your research Which validity threats are ruled out and which
remain
REMEMBER Be thorough Your research design should demonstrate that you
are a competent researcher who is knowledgeable about the proposed research
methodology or methodologies Therefore be sure that you carefully describe
and give technical explanations for each component of your research
B5 Choose a specific situation involving employee selection eg artists for an
advertising agency (a) What strategy would you use in selecting the selection
measures (b) How would you combine the measures eg which measures
would you combine in a compensatory manner and which is a noncompensatory
manner (c) How would you assume test fairness defining various measures of
the term (d) How would you make final selections (e) How would you
validate your procedure (f) What considerations would enter in if your
company were too small to provide validation data (g) What difference would
it make if you were developing a procedure for deciding whether trainees
should be promoted as opposed to making new hires Please note--emphasize
but do not limit yourself to statistical issues
B6 There is evidence in the marketing literature of a non-monotonic relationship
between the expectations that customers have for retail service and their
eventual level of satisfaction with that service That is as a customers
expectations for service increase so does their eventual service satisfaction --
up to a point After that point the greater the expectations the lower the
eventual satisfaction Develop a hypothesis that includes a moderator variable
that might account for this evidence Give some reasonable rationale for it State
your hypothesis verbally as an equation as a directed graph (circle amp arrow
diagram) and as an X-Y function chart Discuss how it would or would not be
possible or useful to test your hypothesis via a laboratory experiment In your
discussion cover how and why a researcher could (not) manipulate the
independent constructs involved (mode X) whether or not random assignment
to conditions (mode R) is possible (including how may conditions would be
necessary) which alternative constructs could or could not be controlled (mode
K) and which constructs should be measured (mode Y)
B7 Assume you are the chairperson of a committee that must evaluate
undergraduate programs at your university Your task as chairperson is to
devise an approach (a design a research strategy a set of measures) that will
allow you to evaluate undergraduate programs Make sure that your approach
can be used in the future and at other comparable universities When developing
your plan be sure to address at least the following issues
a the type of design you would select Compare and contrast the selected design
with another possible design
b the type of research strategy you would select Compare and contrast with
another possible strategies
c discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
B8 Assume you are an organizational research design expert assigned to the
Strategic Planning Department of a large multi-national manufacturing firm
The Department has developed a new PC-based software package called
STRATPACK The software (and a one-week training course to learn how to
use it) is intended to improve the long-range planning ability of middle and
upper-level managers
Your job as research design expert is to devise research (a design a research
strategy a set of measures) that will allow you to evaluate the effectiveness of
the STRATPACK program Describe a research design for evaluating the
program Make sure that your research approach can be used in the future and at
all sites in the company When developing your plan be sure to address at least
the following issues
a discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
b the type of design you would select (eg a design where you manipulate the
independent variable versus observe the independent variable) Compare and
contrast the selected design with another possible design
c how your design deals with the major forms of validity Be sure to examine at
least internal external and construct validity
B9 Assume you are a consultant hired to evaluate the effectiveness of an industrial
safety program undertaken by a large manufacturing organization The safety
program is a behavioral one that provides rewards such as monetary bonuses or
extra paid vacation days for safety behaviors in terms of accident-free days
weeks etc Your task is to devise an approach (a research strategy a design a
set of measures and a general analysis strategy) that will allow you to evaluate
the safety program Because of the potential for the influence of many
extraneous variables on any safety program it is difficult to design research a
single cross-sectional study than can evaluate the impact of a single safety
program How would you design a study to evaluate the impact of the safety
program When developing your plan be sure to address at least the following
issues
a the type of research strategy you would select Compare and contrast with
another possible strategies
b the type of design you would select Compare and contrast the selected design
with another possible design
c discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
B10 One of the most important areas of research is forecasting of human resources
needs based on strategic positions of organizations For example NY State must
carefully forecast its human resources needs as it proceeds with significant lay-
offs of state employees Future human resources needs are generally evaluated
by either statistical ie regression or simulation or clinical judgment i e
supervisors judgments methods
a Design a single study that addresses the empirical question of whether
statistical or judgmental methods are better for forecasting human resources
needs You may discuss a program of research but please be quite specific in
your description of the first study
b What are the critical methodological issues in doing this kind of research
c What are the critical applied (or practical) issues in doing this research
d Are the issues in b and c related
B11 In the past decade computinginformation technology has changed many
aspects of organizational life For example the technology can make increased
decentralization possible by improving communication between central offices
and field offices Computer networks and word processors can enhance group
empowerment by making it possible for team members to create and edit
written group products quickly even if the individuals are at different locations
Some have argued that computinginformation technology will foster the
paperless productive office nevertheless others argue that the technology only
increases paper and reduces office productivity You are applying to the
National Science Foundation for a grant to conduct research that examines the
impact of computing information technology on organizational decision
processes The NSF application procedure imposes five basic requirements that
your research design must fulfill in order to receive funding Note A very
significant factor affecting NSF grant decisions is a clear demonstration that the
researcher is knowledgeable about the research methodology used Write your
response to each of the following five grant requirements Be sure not only to
respond to the requirement but also to demonstrate your research
competence
1You must design a study that uses two different methods
(interviewobservation survey experiment or quasi-experiment) Describe your
two methods in detail and provide a rationale for the key elements (eg
sampling data collection proposed analysis) of your methods Be sure to
discuss and evaluate the internal and external validity of both methods
2 As part of your research design you must select a conceptual (latent) variable
central to your proposal (use centralization of decision making as your
variable) and describe how you will develop your own measure (You may not
simply use off the shelf instruments)
3 You must describe how you will test for the reliability of the measure
(centralization of decision making) you developed in step 2 The NSF insists
that you describe how you will evaluate both the temporal stability and the
internal consistency of your measure Be sure to discuss what temporal stability
and internal reliability mean and how they are related
4You must describe how you will assess the validity of the measure
(centralization of decision making) you developed in step 2
5 NSF requires a brief statement and defense of the philosophy of science
underlying your research Discuss your position and show how your research
design is consistent with your philosophy
B12 Many organizations in the United States economy have installed some form of
Empowered Teams as an alternative or supplement to traditional bureaucratic
structure Preliminary evidence of the effectiveness of empowered teams
however is mixed--some organizations have claimed success and others have
reported failures The evidence however is predominantly anecdotal--written
for trade magazines by the organizations themselves There are few rigorous
empirical studies assessing the effectiveness of empowered or self-managed
teams You are applying to the United States Department of Labor (USDOL) for
a grant to conduct research that examines the effectiveness of empowered
teams The application procedure of the USDOL imposes three requirements
that your research design must fulfill in order to receive funding Write your
response to each of the three grant requirements The importance of each section
is implied by the evaluation points allocated by the USDOL to each of the three
requirements given in parentheses
1 (50 points) Your study design for assessing Empowered Team effectiveness
must use two different methods (interview observation archival analysis
survey simulation experiment or quasi-experiment) Describe in detail and
thoroughly explain the sampling plan instrumentation data collection
procedures and proposed data analyses for both methods Be sure to discuss the
internal and external validity of both methods and how the two methods
complement one another
2 (30 points) As part of your research design you must select one conceptual
(latent) variable central to your proposal and describe how you will develop
your own operationalization of the measure (You may not simply use off the
shelf instruments) Use the concept of group morale to demonstrate your
operationalization methodology Be sure to explain very explicitly to the
USDOL how you will assess the validity and reliability of the group morale
measure you are developing
3 (20 points) The USDOL traditionally has funded research conducted only
within the general paradigm of logical positivism but now is more open to other
research paradigms as well Your grant proposal must provide a statement and
defense of the explicit philosophy of science underlying your research Describe
your philosophy of science and show how your research design is consistent
with your philosophy
REMEMBER Be thorough You not only must design effective research but
you also must demonstrate to the USDOL that you are a competent researcher
It is absolutely vital to the USDOL that the principal researcher is
knowledgeable about the proposed research methodologies Therefore be sure
that you always carefully describe and give technical explanations for each
component of your research design and explain all technical terms (eg
Cronbach alpha KR-20 Likert scale)
B13 Assume that you are working as part of a research team that is responding to a
RFP (Request for Proposals) from a funding agency for research on work
socialization and newcomer adjustment The RFP calls for rigorous field
research that tests the effectiveness of theory-based interventions aimed at
facilitating the adjustment of new organizational members to complex andor
stressful work conditions The major goal of your teams research is to test the
effectiveness of a self-regulation intervention which trains newcomers to
identify and use relevant social information and cues to regulate work behavior
Your group hypothesizes that self-regulation training will be more effective
than other common treatments or interventions (eg realistic job previews
institutionalized socialization tactics)
You have been included in the team because of your methodological expertise
Your role is to design a rigorous field experiment or quasi-experiment to test he
effectiveness of the self-regulation training program REMEMBER THE
MAJOR CRITERION FOR FUNDING IS THE RIGOR OF THE RESEARCH
DESIGN Design a field study to include in the grant proposal Your proposal
should contain the following two sections
1 Study Design Construct and describe in detail an experimental or quasi-
experimental design to test the effectiveness of your intervention Describe in
detail the experimental groups (including how they will be constructed) the
research setting the sampling plan for study participants the treatment
manipulation and the data collection procedures Also indicate any control or
nuisance variables that may be measured
After describing the procedures write a justification of the design What threats
to validity does it rule out or limit and what threats to validity remain
II Measurement Describe the steps you would take to achieve valid and
reliable measure of the latent (conceptual) variable worker adjustment Your
team feels that as part of the proposal you must develop an original
operationalization of adjustment (thus you cannot simply use existing off the
shelf measures) Indicate in adequate detail how you would operationalize the
measure and indicate how you would demonstrate reliability and validity
B14 In describing their notion of the collective mind Karl E Weick and Karlene H
Roberts note Our focus is at once on individuals and the collective since only
individuals can contribute to a collective mind but a collective mind is distinct
from an individual because it inheres in the pattern of interrelated activities
among many people (p 360) Collective mind is not indexed by within-group
similarity of attitudes ideas or activities A collective mind is one in which
many people or many groups integrate their different attitudes ideas and
activities heedfully As Weick and Roberts note People act heedfully when
they act more or less carefully critically consistently purposefully attentively
studiously vigilantly conscientiously pertinaciously (p 361)
The idea of the collective mind as heedful interrelating is developed in the
following excerpt When people make efforts to interrelate these efforts can
range from heedful to heedless The more heed reflected in a pattern of
interrelations the more developed the collective mind and the greater the
capability to comprehend unexpected events that evolve rapidly in unexpected
ways When we say that a collective mind comprehends unexpected events we
mean that heedful interrelating connects sufficient know-how to meet situational
demands For organizations concerned with reliability those developments
often consist of unexpected non-sequential interaction (p366)
An example of heedful interrelating occurs as a pilot lands herhis aircraft on the
deck of an aircraft carrier The pilot does not actually land She is recovered
A recovery is an interrelated set of activities among air traffic controllers
landing signal officers the control tower navigators deck hands the helmsman
driving the ship etc These activities can be interrelated more or less heedfully
depending on the care with which the different units contribute represent the
situation and subordinate their activities to the single purpose of successful

B15 Many organizations in the United States have installed cross-functional teams to
counteract the silo mentality of traditional bureaucratic structure Preliminary
evidence of the effectiveness of cross-functional teams however is mixed --
some organizations have claimed success and others have reported failures The
evidence moreover is predominantly anecdotal--written for trade magazines by
the organizations themselves Since there have been few rigorous empirical
field studies assessing the effectiveness of cross functional teams the National
Science Foundation has decided to fund research on the topic

validity threats are ruled out and which remain NSF also requires that you
provide a statement and defense of the explicit philosophy of science underlying
your research Describe your philosophy of science and discuss how your
research design is consistent with your philosophy

5 MEASUREMENT
A) Measurement Terms
A1 There are four levels of measurement rigor in management research Discuss each
one What properties do measurements at each level have (ie how much
information do the numbers from each level of measurement convey) How can the
numbers be changed (transformed) and still retain the properties of their
measurement level Pick one construct from a favorite research domain and give an
example of an operationalization of that construct at each of the four levels of
measurement rigor (provide arguments about why you think those examples reflect
each level) Lastly treat each examplelevel as a dependent variable in some
statistical analysis Given an example of a statistical technique appropriate for
analyzing data at that level of measurement rigor
A2 Define (and discuss important features or issues concerning) the following
constructs measurement (Define any six terms)

estate agents self-assessment of performance Since there is no existing
measurement available you have to develop the instrument by yourself
Describe how you would develop the measurement assuming that you have no
idea of how many dimension the construct has
b) Suppose you have developed an instrument consists of 20 questions
measuring 4 dimensions (5 items per dimension) from (a) You collected data
from another 300 real estate agents to validate your instrument Explain how
TH
you would use structural equations model (SEM) to examine the reliability and
validity of the instrument What are other concerns about reliability and validity
that are not addressed by this approach
B2 The research and business world have been fascinated with the concept of
organizational culture However operationalizing this construct has been a
difficult task Discuss the ways in which the construct has been operationalized
(eg technique static v dynamic sample selection generalizability) Critically
analyze each of these methodologies Then choose a methodology you would
use to examine organizational culture and defend your choice Describe how
you would study culture and what more would be known about culture as a
result of your study
B3 Suppose you are setting out to develop a new measure of a construct You want
this measure to be used in survey research and you want to establish its validity
and reliability Your goal is to have at the end of the process a measure that is
defensible and likely to be widely accepted by other researchers studying that
construct What steps would you take to conduct such a program of research
For each step explain the purpose of that step explain why that step is
important explain what methods and statistical procedures you would employ at
each step and explain what evidence you would hope to gather at each step

relevant variable from your field) Detail the major concerns that need to be
addressed and the steps that need to be taken in working toward validating this
new measure
B5 Assume that you recently read an article on workplace violence which you
found very interesting The authors argued that one of the predictors of
workplace violence was a construct called propensity to be violent and used a
one-item measure as follows How likely are you to become violent when
provoked You had serious doubts about the authors measure and decided to
develop your own
(a) How would you go about developing items to measure propensity to be
violent
(b) How would you determine whether the instrument was reliable
How would you determine whether the instrument was valid
B6 A concern in organizations is retirement of baby boomers within the next 5 -
10 years This concern is focused on the loss of older employees with skills
critical to the core business functions of organizations In order to continue to
have employees with those critical skills it seems necessary to retrain some
older workers However past practice in most organizations has been not to
retrain older workers for a variety of reasons mostly financial A researcher
working for the Human Resources Department of a large corporation - 13500
employees in 12 different plant locations - hypothesizes that the major reason
for not retraining older workers is ingrained in the culture of the corporation
IC
The researcher feels that older workers are not as highly valued as younger
workers in terms of their potential usefulness after retraining The researcher
searched the literature but found nothing in the existing literature to measure
the cultural value construct What should the researcher do to establish a reliable
and valid self-administered paper and pencil measure of this construct namely
the value of retraining older workers

determine if your operationalization is valid
B8 Organizational researchers have several strategies available to them for
gathering information (eg self-report measures archival measures direct
observation and trace measures) Assume that you are going to conduct
empirical research to assess the role that the structure of the organization plays
in determining the level of organizational effectiveness Briefly review the
strengths and weaknesses of the basic strategies (that is self-report measures
archival measures direct observation and trace measures) for measuring
organizational effectiveness Next describe and justify the steps you would
take to develop an operationalization of the concept of organizational
effectiveness What standards and procedures would you use to determine if
your operationalization is valid
B9 One of the most important topics of recent research has been stress in the work
place One of the most important problems with understanding this literature is
the varying definitions and measurement of this construct Suppose you had
decided to investigate the relationship between stress at the work place and dual
career family happiness

measure of stress at work with other measures of this construct How would you
do that

impact of interpersonal trust on organizational decision making Describe and
justify the steps you might follow to develop an operationalization of the
interpersonal trust concept

analysis of the data
B13 Assume you are interested in developing a new scale to measure construct X
Further assume that you have used previous literature and your own conceptual
development to delineate 2 dimensions of X specifically XF1 and XF2
Describe the steps you would go through in developing testing and evaluating
this new scale With regard to testing and evaluating be sure to consider the
role of factor analysis (both exploratory and confirmatory) and item analysis
Also you will want to make sure that your new multidimensional scale shows
evidence of validity (several kinds) and reliability so be sure to examine these
issues and explain how specific information gathered from the above testing
contributes to these concerns

C1 Describe and discuss the concept of reliability and all of its various forms
including their assessment When is each form appropriate and what information
is provided by each index

measure
C9 Define reliability Name some methods of calculating reliability How well do
these methods map up with the definition of reliability What is the impact of the
number of test items and sample size on Chronbachs alpha and why would this
effect occur or not occur (Note Do NOT discuss inter-rater reliability)
C10 Schmidt and Hunter (1996) described several types of measures typically used in
organizational research and identified the type(s) of measurement error affecting
each of them in various situations For each measure below indicate the types of
error and sources of error that are most likely to affect it Then indicate what
could be done to reduce errors of measurement andor what can be done to
control for errors statistically
a Supervisor ratings of subordinates job performance
b Self-ratings of ones own job performance
c Self-reports of ones own job-related attitudes

worker)
d Aptitude tests taken as part of the hiring process
C11 Suppose you had conducted research on the relationship between organizational
commitment and rigidity of organizational structure in 200 firms Your measure
of rigidity was based on number of organizational authority levels and the degree
to which written organizational rules existed and defined role behaviors for
employees Thus an organization with a large number of organizational levels
and specific written policies defining appropriate role behaviors for employees
would score high on rigidity of organizational structure After analyzing your
data you find that there is a statistically significant negative correlation between
commitment and rigidity which is consistent with your hypothesis However the
reliabilities for your two measures are
(1) commitment = 23 (2) rigidity = 83
How should you interpret your results What could you do to fix this situation
Describe the specific steps (in order) you would follow to develop a more
reliable measure of commitment

interrater agreement and reliability methods be used (Rwg Kappa and Weighted
Kappa percent agreement average pairwise correlation ANOVA methods
(interclass correlation coefficient WABA)) What are the advantages and
disadvantages of each of the methods
(b) Explain the controversy between Frank Schmidt Larry James and others
regarding the differences between interrater agreement and interrater reliability

deal with aggregation issues Critique the methods the authors used to make
aggregation decisions
(d) Provide some advice to researchers regarding what they should do if interrater
agreement and reliability indices indicate that it is not legitimate to aggregate their
data
(e) Provide some ideas for avoiding the need to aggregate in group-level research

research literature This type of research raises many issues and presents many
challenges in terms of designing the research measuring variables and collecting
and analyzing the data Assume that you are interested in aggregating data (eg
from the individual to the group or from the firm to the industry) for one or more
variables What are the major issues you will need to deal with
D3 A researcher wants to measure organizational climate for continuous learning
Organizational climate is operationalized as a shared consensual aspect of the
organization -- the shared perception among employees that the organization values
and supports continuous learning Describe how you would measure organizational
climate in this case Specify (a) the level (ie individual group organization) at
which the construct exists (b) the level at which you would measure the construct
and (c) the procedures that you would use to establish that measurement is aligned
with theory (ie the construct validity of the measure)
E) General (Measurement)
E1 Studies in organizational behavior research often rely on single-item measures of
key constructs The use of single-item measures has long been criticized based
on the premise that single-item measures are unreliable However Wanous
(Wanous amp Hudy 2001 Wanous amp Reichers 1996 Wanous Reichers amp Hudy
1997) has recently argued that single-item measures can exhibit adequate
reliability Wanous based this conclusion on a procedure for estimating the
reliability of single-item measures using the classic formula for correction for
attenuation Subsequent studies have yielded mixed results regarding the
conclusions of Wanous (eg Loo amp Kells 1998 Nagy 2002) and the veracity
of the perspective advocated by Wanous remains in question Summarize and
assess the arguments for and against the use of single-item measures and
evaluate the procedure and evidence offered by Wanous regarding the reliability
of single-item measures Based on your assessment and evaluation develop
recommendations regarding the use of single-item measures in organizational
behavior research

E2 Ipsative measures have become prevalent in organizational behavior research
Ipsative measures ask respondents to answer questions relative to one another
such that the scores for all questions sum to the same constant for all respondents
Examples of ipsative measures include rankings Q-sorts and the allocation of a
fixed number of points (eg 100) across a set of response options Ipsative
measures may be contrasted with absolute measures which ask respondents to
answer questions independently from one another Absolute measures are
exemplified by rating scales using an interval or ratio numeric response format
The relative merits of ipsative and absolute measures have been debated for
decades (eg Cornwell amp Dunlap 1994 Hicks 1970 Johnson Wood amp
Blinkhorn 1988 Saville amp Wilson 1991 1992) yet the fundamental issues
underlying this debate have not been adequately addressed in organizational
behavior research For example measures of organizational culture and values
are often ipsative and some researchers advocate these measures over absolute
measures (eg Meglino amp Ravlin 1987 OReilly Chatman amp Caldwell 1991
Ravlin amp Meglino 1987 see also Rokeach amp Ball-Rokeach 1989) Review the
relative merits of absolute and ipsative measures Based on your review which
form of measurement is most appropriate and why Do your conclusions depend
on the construct being measured If so what types of constructs are best suited to
ipsative measures and what types are best suited to absolute measures Next
apply your conclusions to the measurement of culture and values in
organizations What specific arguments have been advanced in favor of ipsative
measures of culture and values How sound are these arguments Should ipsative
measures be used in the study of organizational culture and values If not how
can absolute measures of culture and values be developed that address the
concerns voiced by advocates of ipsative measures Provide a specific example
of the type of measure you would propose

facets of a concept Although such measures are prevalent and in some cases are
advocated (eg Law et al 1998 1999) they can present a variety of conceptual
and methodological problems Describe the specific problems associated with
measures that use items representing different facets of a concept Compare these
problems with the purported advantages of such measures Conclude by

E5 Suppose Roberta Von Eisenbrick is a researcher interested in the consequences of
AFFECTIVE CONFLICT (AC) in decision-making teams She gets access to a
variety of outcomes assessment committees at each of 87 different schools in
the Dallas Independent School District and gains permission to tape-record two
of their meetings (one in February and one in March) Such committees have
been formed to develop quantitative ways to track pursuit of school goals and
provide accountability to local and state governments These are often divisive
teams with heated meetings because what gets assessed is what usually gets
rewarded After both of these meetings the committee members each
fill out a short questionnaire that contains 20 Likert-type items measuring how
much AC occurred (eg People in our group often get angry with each other)
The individual scores are summed across items then averaged across team
members to come up with a group-level AC score for each of the 87 2
meetings The same procedures are followed for a 5-item measure of Group
Cohesiveness (GC) which is predicted to be reduced by higher levels of AC
Roberta also listens to every tape and from her expert judgment she rates each
groups meetings on the same 20 items Those 20 ratings are summed for each of
the 87 2 meetings Now Roberta is interested in evaluating her measure She
wants it to have excellent psychometric properties including reliability and
construct validity

B2 In recent years (and in not so recent years for that matter) methodologists have
criticized the fact that psychologists rely heavily on significance testing What
are the essential elements of these critiques What are some remedies to the
problems engendered by significance testing and why have these remedies not
been widely adopted

whether we should abandon significance testing and report confidence intervals
instead Please summarize arguments from both sides and state your position on
this issue

(a) Please define both of these terms (b) Sketch a conceptual model to show how
each relates to main effects (c) Using variables of your choice please write
hypotheses to reflect both (d) Explain how each is tested analytically
D2 Discuss moderators and mediators Provide an example of how (1) a moderating
variable influences the relationship between the independent and dependent
variable and how (2) a mediating variable influences the relationship between
the independent and dependent variable Describe how you would test for both
moderation and mediation using regression
D3 Many theories in organizational research predict that the effects of one variable
on another are moderated by a third variable Such moderator effects are
typically tested by entering the product of two variables as a predictor after
controlling for the two variables that constitute the product Several researchers
have pointed out that this product is often highly correlated with the squares of
the two constituent variables and have suggested that moderating effects may be
tested after controlling not only for the two constituent variables but also their
squares (eg Cortina 1993 Ganzach 1998 Lubinski amp Humphreys 1990
MacCallum amp Mar 1995) Discuss the strengths and weaknesses of this
approach as compared to methods that use only the product term and its
constituent variables Conclude with recommendations as to when and under
what conditions organizational researchers should test moderator effects with the
squares of the constituent variables in the equation

Y and Z Your first hypothesis posits Z as a mediator of the relationship between
X and Y Your second hypothesis posits Z as a moderator of the relationship
between X and Y Draw the figures depicting each of these hypothesized
relationships and describe (make sure to write regression equations) how you
would test each of these hypotheses

working one more week per year than the average person in the mid 1970s This
steady increase has fueled research interest in the construct of Job Burnout (JB)
which is an emotional and physical exhaustion associated with ones work
Organizational Stress (OS) the perception of greater demands than available
resources in ones work environment is thought to be one of the chief
antecedents of JB However time spent under OS is thought to make its affects
on JB accumulate or worsen Work Role Withdrawal (WRW) the avoidance of
responsibilities or the deliberate reduction of inputs to ones job is believed to be
the chief consequence of JB
a Formally state these ideas as verbal hypotheses as equations and as a complex
directed graph (circle amp arrow diagram)

subdomains of management Further demonstrate your understanding of
moderator variables by picking which variable in (a) is the moderator Show the
moderating relationship in an X-Y (or multi-layered) chart Again what elements

E) Multiple Comparisons
E1 In your role as professional colleague you are called upon to advise another doctoral
student about the appropriate use of multiple comparisons and post hoc tests in
analysis of variance Your student colleague already has been introduced to ANOVA
and multiple regression Specifically you are to write out a description of how to test
for differences among the different levels or cells of a categorical variable In your
description you should discuss among other things
a the statistical and philosophical issues raised by post hoc analysis and data
snooping
b the different multiple comparison methods commonly used by researchers to test
for differences among cell means and
c the advantages and disadvantages of each method
Note Your written description will be evaluated based on your demonstrated
competence with the statistical method not on the pedagogy of your explanation
F) Applied Data Analysis
16) Q Your departmental chair is considering a new textbook and has asked for your
recommendations You conduct a well-designed controlled study (details are unimportant) and discover students who use the new book perform 10 better on a standardized subject
matter exam than those using the old book (p = 027) Both books are readily availabe their prices are almost identical and both are equally acceptable to the instructors What is your recommendation to the chair
F1 Attached is the beginning of an article Your task is to write the results section by
1 making up and reporting plausible descriptive statistics that will help the
reader understand the results of the statistical tests you report and the nature of your
sample (Hint this can be presented in the form of a table)
2 describing and defending your choice of appropriate statistical tests of the
hypotheses and the steps that you would go through in carrying out these tests
3 making up and reporting results of these tests that are consistent with your
descriptive statistics and with any information in the rest of the article about the
results found (Hint this can be presented in the form of a table)
4 describing how well these results provide support for the hypotheses You
may want to note any relevant threats to validity here
Be sure to state any assumptions you make
F2 Assume that the Personnel Manager of a local firm Ms B dFlandres hired you to
analyze some data that her assistants had collected over the past several years The
data consist of (a) job performance ratings that were made in June of 1990 and (b)
scores on 25 predictor variables (eg measures of education job experience job
tenure job aptitude personality) that were measured when the individuals were hired
(between April 1987 and May 1988) She had data from only the 110 subjects (60
males and 50 females) who were hired during the period and were still employed by
the firm One objective of your analysis (analyses) is to determine how well the
performance criterion can be predicted by the predictors What strategy would you
use in analyzing the data Describeexplain (b) Is sample size an issue for your
analyses Explain If it is what will you do to deal with problems stemming from
sample size Assume that no additional data can be collected at this time (c) Some
preliminary analyses that you do reveal that five of the predictor variables correlate
(zero-order basis) about 75 with one another Will this influence the analyses that
you use Will it influence the validity of conclusions derived from your proposed
analyses (d) Ms dFlandres is interested in knowing if the predictor variables are
equally effective in predicting the job success of males and females What analysis
or analyses would you do to deal with this issue
F3 Assume that you have been provided with data on 12 conceptually distinct variables
that are moderately correlated with one another at the empirical level The data are
from students in four different college majors ie astronomy (A) biology (B)
criminology (C) and demography (D) The 12 measured variables fall into the
general categories of mental health (tension emotional withdrawal hallucinations
guilt feelings blunted affect and suspiciousness) and job satisfaction (work itself
supervision co-workers pay promotion prospects and working conditions) Your
task is to determine if the individuals in the four college majors differ from one
another on the 12 measured variables
(a) What statistical technique(s) would you use to test for group differences
Explain Be specific about the procedures(s) that you would use
(b) What statistical estimate would you use to estimate the extent to which the
groups differ from one another Be specific
F4 The following statistical table published in a recent issue of Work amp Occupations
was taken from an article discussing variables influencing resistance and citizenship
behaviors in the workplace Resistance behaviors include playing dumb withholding
effort work avoidance subverting particular managers and sabotage Citizenship
behaviors include cooperation engaging in peer training use of insider knowledge to
facilitate production commitment to organizational goals giving extra effort freely
Both measures are global constructs aggregated to the interval level and
standardized
The table reports the results of a series of ordinary least squares regression equations
with standardized coefficients Explain the meaning of the statistics presented What
do these statistics tell us generally about the relationship between resistance
behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows
Anomie Index -standardized interval level measure tapping multiple dimensions
The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)
F5 Researchers collected data from a sample of 350 companies on the following
variables
size (measured as number of employees)
Business Strategy (a nominal variable with 2 response options low-cost provider or
differentiator)
HR Strategy (a nominal variable with 2 response categories High commitment or
low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

interaction What if anything would you do with the sum of squares for the
interaction effect
I2 A study examined the effects of gender and pre-training motivation on the transfer of
training in terms of improved performance for 123 new industrial managers The
training was on supervisory skills and the dependent variable was based on the
appraisal of the supervisors performance before the training and three months after
the training The performance appraisal data were collected for research purposes
only and resulted in a total transfer score from 1 to 25 with 1 being low Pre-training

mirrors Explain both sides of the debate and then lay out the role of meta-analysis
as you see it within the time span of your career as an academic To do this use
examples of already written (or yet to be written) articles as models
J5 A frequent criticism of non-quantitative research summaries (literature reviews) is
that researchers do not carefully examine how particular research designs might have
affected the statistical outcomes of the studies included in the literature review Meta-
analysis however allows one to statistically examine such effects Assume you are
conducting a meta-analysis of the relationship between leader behaviors and group
productivity Briefly describe the steps you would take in conducting a meta-
analysis What aspects of the original research designs would you examine in your
meta-analysis What steps would you take in gathering and coding data to enhance
the credibility of your analysis

and discuss the assumptions of the general linear model Multiple regression
ANOVA and principle components (factor) analysis are based on the general linear
model For each of those three statistical procedures describe and discuss the
following

assumptions usage and limitations
O3 How do exploratory and confirmatory factor analysis differ What are the
advantages and disadvantages of each
O4 Describe the differences between exploratory factor analysis (EFA) and
confirmatory factor analysis (CFA) When would you use one verses another
Are there ways to use EFA in a confirmatory way Can you use CFA in an
exploratory way Also describe the difference in principal components analysis
(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression

information in each matrix and its purpose
(2) For what purpose do researchers use factor analysis Explain In the process
provide a very brief description of a study for which factor analysis would be a
useful data analytic technique
O7 Factor analysis is an important statistical technique in organizational research

c the type of quantitative output that results from applying the technique
d how a researcher would use the output in his or her research

f the important issues and problems in using the technique
P) Structural Equation Models
P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

parameter estimate bias in structural equation modeling Structural Equation

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)
Please comment on these restrictions versus access argument Which side do you
take
What are the strengths of SEM Give some examples
What are the weaknesses of SEM Give some examples

K) Data Collection Methods
14) Describe the various methods of data collection (eg survey interview observation etc)
available to a social scientist What are the advantages and disadvantages of each relative to
each other
K1 Within micro organizational research much criticism has been raised concerning
the reliance on self-report survey data What potential problems does self-report
survey research raise How big of a problem do you think this is
K2 There are a number of methods for collecting data (eg survey interview archival
etc) that are available to a social scientistorganizational researcher Discuss each in
terms of their strengths and weaknesses both on their own and in comparison to one
another
K3 Pick an important construct in your favorite area of management research for which
there is some controversy about how it should be measured or operationalized (eg
environmental munificence or growth need strength) Give the prevailing verbal
definition of the construct and analyze the measurement controversy from two
broad angles First discuss how the controversy may or may not stem from claims
about how one measure is better or worse than another because it (or the other) is an
(a) archival record (b) direct observation (c) social report or (d) self-report That is
what are the relative strengths and weaknesses of each of these types of
measurement for the construct youre discussing Second discuss the construct
validity of the most commonly used measure(s) of this construct To answer this
second part you need to discuss just what construct validity is and how it can or
cannot be demonstrated In the situation you describe what could be done to
demonstrate or improve the construct validity of existing measures
K4 Interviewing in some form has been the workhorse for data collection in a variety
of research traditions positivistquantitative ethnographic feministpost-modernist
and increasingly historical research While each tradition elicits information from
respondents the goals and processes involved in interviewing vary considerably
across research traditions Discuss the purposes of the interview the relationship
between data and theory the roles assumed by the interviewer and the respondent
and the relevant criteria for assessing the validity and reliability of the information
obtained In addition compare and contrast the use of the interview as a data
collection method in the positivistquantitative tradition with its use in one of the
alternative traditions
L) Common Method Variance
L1 Many of us have had concerns about the reviews of our survey research which
suggest that data analyses of surveys are biased because of common method
variance effects of individual differences such as negative mood negative
affectivity and social desirability and the reliability and validity of the constructs
we are attempting to measure Define how these problems affect a research issue in
organizational behavior and the steps that might be taken to minimize such potential
criticisms of papers based on analyses of self-reported data through survey
instruments
L2 In a series of papers by Spector (1994) Schmitt (1994) and Howard (1994)
published in the Journal of Organizational Behavior arguments were provided for
and against the use of self-report questionnaire measures One of the issues
discussed that could limit conclusions drawn from relationships observed using self-
report measures was method variance What is meant by method variance what are
its sources and what impact is it expected to have on research findings
M) Sampling
M1 The manufacturing census samples all plants of 250 employees or more For
plants of 5-249 employees it takes a size proportional sample Plants of 1-4
employees are not sampled What challenges does this sampling method provide
to researchers What could you do to account for these problems if you were
TH
studying organizational (not plant) growth
M2 New York State has approximately 250000 employees in over 70 state agencies
commissions and boards ranging in size from approximately 50 to over 5000
employees Assume that you wanted to draw a representative sample of 1000
employees Describe two ways that you could draw such a sample and briefly
describe the advantages and disadvantages of each of these sampling approaches
IC
M3 The director of a national non-profit agency with approximately 10000
employees located primarily in regional offices in each of the 50 states the
United States has approached you and asked you to develop a study
(organizational survey) of organizational culture within the agency The agency
is about to embark on a variety of change initiatives including developing team
structures and the study is meant to examine various elements of organizational
culture that are potential barriers to change The director has indicated that he
would like to have the data analyzed at both the individual and office level of
analysis Because of funding limitations the agency will only be able to send the
survey to 1000 employees The director has indicated that there are three ways
of sorting employees all employees listed alphabetically all employees listed
alphabetically by state and all employees listed alphabetically by region (there
are between five and ten regions per state) Given these three ways of sorting
employees describe at least three different sampling approaches and the
advantages and disadvantages of each
M4 In your role as Teacher of Organizational Studies you are asked to prepare a
tutorial for beginning doctoral students on sampling design Assume that this
tutorial is part of a basic class in research design and that students in this class
have had a basic statistics course up to and including multiple regression Your
tutorial should focus on briefly defining and explaining the differences between
probability and non-probability samples You should make sure to present and
describe several types of probability samples (eg random systematic
stratified etc) and non-probability samples (eg convenience snow-ball quota
etc) and discuss general principles for when to use a probability vs a non-
probability sampling design For each sampling design you should also provide
at least one clear example of a situation where this type of sampling design is
appropriate
N) Cross-Cultural Research
N1 Discuss the problems in conducting cross-culturalnational comparison in terms
of (1) conceptualization and (2) research design and data collection
Define the three levels of measurement invariance How would the problems that
you have identified in part (a) affect measurement invariance How would you
examine measurement invariance by confirmatory factor analysis
TH
N2 Explain why using national boundaries as independent variable in cross-cultural
studies may not be appropriate in terms of theory and research methods What
alternative ways would you recommend
IC
O) General
O1 In your readings research has been described as choices among conflicting goals
(desiderata) For instance when choosing among research strategies a researcher
must choose among the desiderata of precision realism and generalizability The
trade-offs among desiderata occur for all aspects of research that is for the selection
of theories the treatment of independent variables research strategies the selection
of the problem to study rules of evidence for determining the meaningfulness of a
research finding and even the frameworks that describe the research process
Discuss what you see as the major trade-offs for each of the following aspects of
research That is discuss what you see as the major strengths and weaknesses
(advantages and disadvantages) of each aspect
a The trade-offs between internal and external validity
b The manipulation of the independent variable vs the observation of the
independent variable
c Basic vs applied research
3 DESIGNING A RESEARCH STUDY
A) General (Research Design)
3) Why is control so important in research design What are the different ways it can be
achieved (give a brief description of each control method) What are advantages and
disadvantages of each
A1 It has become almost a truism to note that the choice of methods influences theory
and questions data and conclusions (the causal direction might also be reversed)
Briefly discuss how the methods used have influenced research in any two of the
following areas leadership power and politics organization culture organization
justice Compare and contrast as possible Suggest some potentially fruitful
methodological directions for future work in these same topical areas and dont be
shy about reflecting on broader issues of how the field of organizational behavior
constructs its realities Lastly tie your discussion and reflections back to your own
future as a researcher what lessons or guidance do you derive from your
understanding of these issues
A2 Characterize as fully as possible what you see to be the methodological approach or
approaches in strategic management research Is there a dominant method or a wide
variety Discuss the reasons for the situation What are the advantages benefits etc
of the approach(es) in use What assumptions (ontological epistemological
ideological) do they embody Are current efforts ideal or at least adequate Are
there other approaches that could be useful If so how might researchers be
encouraged to use these as well If you see no advantage to more variety in
methodological approach support that point of view
A3 Describe a research question or area of interest to you and why you think it is not
only of interest but significance Using your understanding of research methodology
describe two ways of pursing the question that are as divergent on as many
dimensions as you can imagine Describe the advantages and disadvantages of each
approach How strong a link or fit is there between a research question and a
method
A4 In his 1957 article entitled The two disciplines of scientific psychology Cronbach
discussed the assumptions goals and methods used in experimental methods and
correlational methods in psychology
a According to Cronbach what is the main difference between the two disciplines
b Discuss the strength and weaknesses of each discipline
c What if anything could be done to improve the situation
B) Designing a Research Study
B1 Cook and Campbell describe the experiment as the research design with the
greatest methodological rigor However given the constraints present in most
organizations I-O Psychologists cannot often conduct experiments in applied
settings and must settle for techniques with less control than experiments
Describe a study to investigate the relationship between participation in a
supervisor training program and work performance which could realistically be
conducted in an organization If an experiment is not possible describe how you
would go about maximizing your ability to draw valid conclusions from your
design
B2 The XYZ Co has recently developed a sexual harassment web-based training
program The developers claim the program will cut training time and costs and
will be as effective or more effective than classroom-based sessions They
believe that this will be due to the increased availability of the program and the
ability for participants to review program material on demand Before the XYZ
Co developers launch this product they want you to determine if their claims
have merit Explain how you would design a study for this purpose
B3 Research suggests that demographic diversity improves group creativity but
reduces group efficiency Some argue that demographic diversity is just a proxy
for value and experience diversity and that demographic diversity on its own is
meaningless Design a test to settle this argument
TH
B4 E-mail has become a common form of communication in organizations and is
used for both formal and informal communication Because it has become so
IC
popular some people complain that the frequent use of e-mail leads to
miscommunication because they receive communications in e-mail that should
be accomplished through face-to-face or telephone conversations where there is
an opportunity for interaction You are interested in looking at this
phenomenon You are most interested in describing how e-mail is used for both
formal and informal communication and in examining the effect of the e-mail
use on organizational communication effectiveness Design empirical research
to address those issues
Describe your study in detail thoroughly explaining the research design
sampling plan data collection procedures ethical issues and proposed data
analysis for your research design Be sure to discuss the internal and external
validity of your research Which validity threats are ruled out and which
remain
REMEMBER Be thorough Your research design should demonstrate that you
are a competent researcher who is knowledgeable about the proposed research
methodology or methodologies Therefore be sure that you carefully describe
and give technical explanations for each component of your research
B5 Choose a specific situation involving employee selection eg artists for an
advertising agency (a) What strategy would you use in selecting the selection
measures (b) How would you combine the measures eg which measures
would you combine in a compensatory manner and which is a noncompensatory
manner (c) How would you assume test fairness defining various measures of
the term (d) How would you make final selections (e) How would you
validate your procedure (f) What considerations would enter in if your
company were too small to provide validation data (g) What difference would
it make if you were developing a procedure for deciding whether trainees
should be promoted as opposed to making new hires Please note--emphasize
but do not limit yourself to statistical issues
B6 There is evidence in the marketing literature of a non-monotonic relationship
between the expectations that customers have for retail service and their
eventual level of satisfaction with that service That is as a customers
expectations for service increase so does their eventual service satisfaction --
up to a point After that point the greater the expectations the lower the
eventual satisfaction Develop a hypothesis that includes a moderator variable
that might account for this evidence Give some reasonable rationale for it State
your hypothesis verbally as an equation as a directed graph (circle amp arrow
diagram) and as an X-Y function chart Discuss how it would or would not be
possible or useful to test your hypothesis via a laboratory experiment In your
discussion cover how and why a researcher could (not) manipulate the
independent constructs involved (mode X) whether or not random assignment
to conditions (mode R) is possible (including how may conditions would be
necessary) which alternative constructs could or could not be controlled (mode
K) and which constructs should be measured (mode Y)
B7 Assume you are the chairperson of a committee that must evaluate
undergraduate programs at your university Your task as chairperson is to
devise an approach (a design a research strategy a set of measures) that will
allow you to evaluate undergraduate programs Make sure that your approach
can be used in the future and at other comparable universities When developing
your plan be sure to address at least the following issues
a the type of design you would select Compare and contrast the selected design
with another possible design
b the type of research strategy you would select Compare and contrast with
another possible strategies
c discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
B8 Assume you are an organizational research design expert assigned to the
Strategic Planning Department of a large multi-national manufacturing firm
The Department has developed a new PC-based software package called
STRATPACK The software (and a one-week training course to learn how to
use it) is intended to improve the long-range planning ability of middle and
upper-level managers
Your job as research design expert is to devise research (a design a research
strategy a set of measures) that will allow you to evaluate the effectiveness of
the STRATPACK program Describe a research design for evaluating the
program Make sure that your research approach can be used in the future and at
all sites in the company When developing your plan be sure to address at least
the following issues
a discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
b the type of design you would select (eg a design where you manipulate the
independent variable versus observe the independent variable) Compare and
contrast the selected design with another possible design
c how your design deals with the major forms of validity Be sure to examine at
least internal external and construct validity
B9 Assume you are a consultant hired to evaluate the effectiveness of an industrial
safety program undertaken by a large manufacturing organization The safety
program is a behavioral one that provides rewards such as monetary bonuses or
extra paid vacation days for safety behaviors in terms of accident-free days
weeks etc Your task is to devise an approach (a research strategy a design a
set of measures and a general analysis strategy) that will allow you to evaluate
the safety program Because of the potential for the influence of many
extraneous variables on any safety program it is difficult to design research a
single cross-sectional study than can evaluate the impact of a single safety
program How would you design a study to evaluate the impact of the safety
program When developing your plan be sure to address at least the following
issues
a the type of research strategy you would select Compare and contrast with
another possible strategies
b the type of design you would select Compare and contrast the selected design
with another possible design
c discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
B10 One of the most important areas of research is forecasting of human resources
needs based on strategic positions of organizations For example NY State must
carefully forecast its human resources needs as it proceeds with significant lay-
offs of state employees Future human resources needs are generally evaluated
by either statistical ie regression or simulation or clinical judgment i e
supervisors judgments methods
a Design a single study that addresses the empirical question of whether
statistical or judgmental methods are better for forecasting human resources
needs You may discuss a program of research but please be quite specific in
your description of the first study
b What are the critical methodological issues in doing this kind of research
c What are the critical applied (or practical) issues in doing this research
d Are the issues in b and c related
B11 In the past decade computinginformation technology has changed many
aspects of organizational life For example the technology can make increased
decentralization possible by improving communication between central offices
and field offices Computer networks and word processors can enhance group
empowerment by making it possible for team members to create and edit
written group products quickly even if the individuals are at different locations
Some have argued that computinginformation technology will foster the
paperless productive office nevertheless others argue that the technology only
increases paper and reduces office productivity You are applying to the
National Science Foundation for a grant to conduct research that examines the
impact of computing information technology on organizational decision
processes The NSF application procedure imposes five basic requirements that
your research design must fulfill in order to receive funding Note A very
significant factor affecting NSF grant decisions is a clear demonstration that the
researcher is knowledgeable about the research methodology used Write your
response to each of the following five grant requirements Be sure not only to
respond to the requirement but also to demonstrate your research
competence
1You must design a study that uses two different methods
(interviewobservation survey experiment or quasi-experiment) Describe your
two methods in detail and provide a rationale for the key elements (eg
sampling data collection proposed analysis) of your methods Be sure to
discuss and evaluate the internal and external validity of both methods
2 As part of your research design you must select a conceptual (latent) variable
central to your proposal (use centralization of decision making as your
variable) and describe how you will develop your own measure (You may not
simply use off the shelf instruments)
3 You must describe how you will test for the reliability of the measure
(centralization of decision making) you developed in step 2 The NSF insists
that you describe how you will evaluate both the temporal stability and the
internal consistency of your measure Be sure to discuss what temporal stability
and internal reliability mean and how they are related
4You must describe how you will assess the validity of the measure
(centralization of decision making) you developed in step 2
5 NSF requires a brief statement and defense of the philosophy of science
underlying your research Discuss your position and show how your research
design is consistent with your philosophy
B12 Many organizations in the United States economy have installed some form of
Empowered Teams as an alternative or supplement to traditional bureaucratic
structure Preliminary evidence of the effectiveness of empowered teams
however is mixed--some organizations have claimed success and others have
reported failures The evidence however is predominantly anecdotal--written
for trade magazines by the organizations themselves There are few rigorous
empirical studies assessing the effectiveness of empowered or self-managed
teams You are applying to the United States Department of Labor (USDOL) for
a grant to conduct research that examines the effectiveness of empowered
teams The application procedure of the USDOL imposes three requirements
that your research design must fulfill in order to receive funding Write your
response to each of the three grant requirements The importance of each section
is implied by the evaluation points allocated by the USDOL to each of the three
requirements given in parentheses
1 (50 points) Your study design for assessing Empowered Team effectiveness
must use two different methods (interview observation archival analysis
survey simulation experiment or quasi-experiment) Describe in detail and
thoroughly explain the sampling plan instrumentation data collection
procedures and proposed data analyses for both methods Be sure to discuss the
internal and external validity of both methods and how the two methods
complement one another
2 (30 points) As part of your research design you must select one conceptual
(latent) variable central to your proposal and describe how you will develop
your own operationalization of the measure (You may not simply use off the
shelf instruments) Use the concept of group morale to demonstrate your
operationalization methodology Be sure to explain very explicitly to the
USDOL how you will assess the validity and reliability of the group morale
measure you are developing
3 (20 points) The USDOL traditionally has funded research conducted only
within the general paradigm of logical positivism but now is more open to other
research paradigms as well Your grant proposal must provide a statement and
defense of the explicit philosophy of science underlying your research Describe
your philosophy of science and show how your research design is consistent
with your philosophy
REMEMBER Be thorough You not only must design effective research but
you also must demonstrate to the USDOL that you are a competent researcher
It is absolutely vital to the USDOL that the principal researcher is
knowledgeable about the proposed research methodologies Therefore be sure
that you always carefully describe and give technical explanations for each
component of your research design and explain all technical terms (eg
Cronbach alpha KR-20 Likert scale)
B13 Assume that you are working as part of a research team that is responding to a
RFP (Request for Proposals) from a funding agency for research on work
socialization and newcomer adjustment The RFP calls for rigorous field
research that tests the effectiveness of theory-based interventions aimed at
facilitating the adjustment of new organizational members to complex andor
stressful work conditions The major goal of your teams research is to test the
effectiveness of a self-regulation intervention which trains newcomers to
identify and use relevant social information and cues to regulate work behavior
Your group hypothesizes that self-regulation training will be more effective
than other common treatments or interventions (eg realistic job previews
institutionalized socialization tactics)
You have been included in the team because of your methodological expertise
Your role is to design a rigorous field experiment or quasi-experiment to test he
effectiveness of the self-regulation training program REMEMBER THE
MAJOR CRITERION FOR FUNDING IS THE RIGOR OF THE RESEARCH
DESIGN Design a field study to include in the grant proposal Your proposal
should contain the following two sections
1 Study Design Construct and describe in detail an experimental or quasi-
experimental design to test the effectiveness of your intervention Describe in
detail the experimental groups (including how they will be constructed) the
research setting the sampling plan for study participants the treatment
manipulation and the data collection procedures Also indicate any control or
nuisance variables that may be measured
After describing the procedures write a justification of the design What threats
to validity does it rule out or limit and what threats to validity remain
II Measurement Describe the steps you would take to achieve valid and
reliable measure of the latent (conceptual) variable worker adjustment Your
team feels that as part of the proposal you must develop an original
operationalization of adjustment (thus you cannot simply use existing off the
shelf measures) Indicate in adequate detail how you would operationalize the
measure and indicate how you would demonstrate reliability and validity
B14 In describing their notion of the collective mind Karl E Weick and Karlene H
Roberts note Our focus is at once on individuals and the collective since only
individuals can contribute to a collective mind but a collective mind is distinct
from an individual because it inheres in the pattern of interrelated activities
among many people (p 360) Collective mind is not indexed by within-group
similarity of attitudes ideas or activities A collective mind is one in which
many people or many groups integrate their different attitudes ideas and
activities heedfully As Weick and Roberts note People act heedfully when
they act more or less carefully critically consistently purposefully attentively
studiously vigilantly conscientiously pertinaciously (p 361)
The idea of the collective mind as heedful interrelating is developed in the
following excerpt When people make efforts to interrelate these efforts can
range from heedful to heedless The more heed reflected in a pattern of
interrelations the more developed the collective mind and the greater the
capability to comprehend unexpected events that evolve rapidly in unexpected
ways When we say that a collective mind comprehends unexpected events we
mean that heedful interrelating connects sufficient know-how to meet situational
demands For organizations concerned with reliability those developments
often consist of unexpected non-sequential interaction (p366)
An example of heedful interrelating occurs as a pilot lands herhis aircraft on the
deck of an aircraft carrier The pilot does not actually land She is recovered
A recovery is an interrelated set of activities among air traffic controllers
landing signal officers the control tower navigators deck hands the helmsman
driving the ship etc These activities can be interrelated more or less heedfully
depending on the care with which the different units contribute represent the
situation and subordinate their activities to the single purpose of successful
recovery (p 363)
You are to design a two-part study
Part I You are to design a measurement study which assesses heedful
interrelating (ie collective mind) with a quantitative measure in a replication
of an aircraft carrier flight deck or other situation of your choosing Describe
your research strategies including operationalization of the variable selection of
the sample subjects data collection data analysis and so on for the purpose of
developing a measure of heedful interrelating
Part II Using the measurement tool developed in Part I and any other tools as
needed describe how you would design a study which would compare heedful
interrelating across organizations Choose at least one macro-organizational
variable (eg technology environment) as your basis of comparison Here you
must describe how you would make your selection of organizations to be
compared your data collection procedure data analysis and so on
B15 Many organizations in the United States have installed cross-functional teams to
counteract the silo mentality of traditional bureaucratic structure Preliminary
evidence of the effectiveness of cross-functional teams however is mixed --
some organizations have claimed success and others have reported failures The
evidence moreover is predominantly anecdotal--written for trade magazines by
the organizations themselves Since there have been few rigorous empirical
field studies assessing the effectiveness of cross functional teams the National
Science Foundation has decided to fund research on the topic
Assume that you are submitting a research proposal to NSF for a grant to
research the effectiveness of cross-functional teams Describe in detail and
thoroughly explain the research design sampling plan data collection
procedures ethical issues and proposed data analysis for your research design
Be sure to discuss the internal and external validity of your research Which
validity threats are ruled out and which remain NSF also requires that you
provide a statement and defense of the explicit philosophy of science underlying
your research Describe your philosophy of science and discuss how your
research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but
you must also demonstrate to NSF that you are a competent researcher It is
absolutely vital to NSF that the principal researcher (you) is knowledgeable
about the proposed research methodologies Therefore be sure that you always
carefully describe and give technical explanations for each component of your
research design and explain all technical terms (eg Cronbach alpha KR-20
Likert scale)
B16 Assume that you are submitting a research proposal to the Department of
Commerce (DoC) for a grant to research the effectiveness of virtual work teams
A virtual work team is a leaderless collection of individuals who are
geographically separate from one another and share their expertise using
internet media such as a listserver or Lotus notes The DoC requires that the
researcher use both qualitative and quantitative methods to gather data Describe
in detail and thoroughly explain the research design sampling plan data
collection procedures ethical issues and proposed data analysis for your
research design Be sure to discuss the internal and external validity of your
research Which validity threats are ruled out and which remain The DoC also
requires that you provide a statement and defense of the explicit philosophy of
science underlying your research Describe your philosophy of science and
discuss how your research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but
you must also demonstrate to DoC that you are a competent researcher It is
absolutely vital to DoC that the principal investigator (you) is knowledgeable
about the proposed research methodologies Therefore be sure that you always
carefully describe and give technical explanations for each component of your
research

that improves upon the key validity (or validities)
5 MEASUREMENT
A) Measurement Terms
A1 There are four levels of measurement rigor in management research Discuss each
one What properties do measurements at each level have (ie how much
information do the numbers from each level of measurement convey) How can the
numbers be changed (transformed) and still retain the properties of their
measurement level Pick one construct from a favorite research domain and give an
example of an operationalization of that construct at each of the four levels of
measurement rigor (provide arguments about why you think those examples reflect
each level) Lastly treat each examplelevel as a dependent variable in some
statistical analysis Given an example of a statistical technique appropriate for
analyzing data at that level of measurement rigor
A2 Define (and discuss important features or issues concerning) the following
constructs measurement (Define any six terms)
1 Construct validity 6 Item analysis
2 Likert scaling 7 Semantic differential
3 Cronbachs alpha 8 True score
4 Unobtrusive (trace) measurement 9 Generalizability theory
5 Interval scale 10 Criterion-related validity
11 Sociometric choice measures
B) Operationalization
B1 a) You are conducting a study which requires you to measure Hong Kong real
estate agents self-assessment of performance Since there is no existing
measurement available you have to develop the instrument by yourself
Describe how you would develop the measurement assuming that you have no
idea of how many dimension the construct has
b) Suppose you have developed an instrument consists of 20 questions
measuring 4 dimensions (5 items per dimension) from (a) You collected data
from another 300 real estate agents to validate your instrument Explain how
TH
you would use structural equations model (SEM) to examine the reliability and
validity of the instrument What are other concerns about reliability and validity
that are not addressed by this approach
B2 The research and business world have been fascinated with the concept of
organizational culture However operationalizing this construct has been a
difficult task Discuss the ways in which the construct has been operationalized
(eg technique static v dynamic sample selection generalizability) Critically
analyze each of these methodologies Then choose a methodology you would
use to examine organizational culture and defend your choice Describe how
you would study culture and what more would be known about culture as a
result of your study
B3 Suppose you are setting out to develop a new measure of a construct You want
this measure to be used in survey research and you want to establish its validity
and reliability Your goal is to have at the end of the process a measure that is
defensible and likely to be widely accepted by other researchers studying that
construct What steps would you take to conduct such a program of research
For each step explain the purpose of that step explain why that step is
important explain what methods and statistical procedures you would employ at
each step and explain what evidence you would hope to gather at each step
B4 Assume you are interested in constructing a new measure of (fill in with a
relevant variable from your field) Detail the major concerns that need to be
addressed and the steps that need to be taken in working toward validating this
new measure
B5 Assume that you recently read an article on workplace violence which you
found very interesting The authors argued that one of the predictors of
workplace violence was a construct called propensity to be violent and used a
one-item measure as follows How likely are you to become violent when
provoked You had serious doubts about the authors measure and decided to
develop your own
(a) How would you go about developing items to measure propensity to be
violent
(b) How would you determine whether the instrument was reliable
How would you determine whether the instrument was valid
B6 A concern in organizations is retirement of baby boomers within the next 5 -
10 years This concern is focused on the loss of older employees with skills
critical to the core business functions of organizations In order to continue to
have employees with those critical skills it seems necessary to retrain some
older workers However past practice in most organizations has been not to
retrain older workers for a variety of reasons mostly financial A researcher
working for the Human Resources Department of a large corporation - 13500
employees in 12 different plant locations - hypothesizes that the major reason
for not retraining older workers is ingrained in the culture of the corporation
IC
The researcher feels that older workers are not as highly valued as younger
workers in terms of their potential usefulness after retraining The researcher
searched the literature but found nothing in the existing literature to measure
the cultural value construct What should the researcher do to establish a reliable
and valid self-administered paper and pencil measure of this construct namely
the value of retraining older workers
a Please describe and explain the steps in temporal order that the researcher
must follow to develop a measure
b How would you evaluate the measure based on the technical requirements of
reliable and valid measurement as well as any practical issues in using the
measure considering the size of the employee population
B7 Assume that you are going to conduct empirical research to assess the role that
the complexity of an organizations manufacturing technology plays in
determining the level of centrality of decision making in the organization
Describe and justify the steps you might follow to develop an operationalization
of the concept of technological complexity What standards would you use to
determine if your operationalization is valid
B8 Organizational researchers have several strategies available to them for
gathering information (eg self-report measures archival measures direct
observation and trace measures) Assume that you are going to conduct
empirical research to assess the role that the structure of the organization plays
in determining the level of organizational effectiveness Briefly review the
strengths and weaknesses of the basic strategies (that is self-report measures
archival measures direct observation and trace measures) for measuring
organizational effectiveness Next describe and justify the steps you would
take to develop an operationalization of the concept of organizational
effectiveness What standards and procedures would you use to determine if
your operationalization is valid
B9 One of the most important topics of recent research has been stress in the work
place One of the most important problems with understanding this literature is
the varying definitions and measurement of this construct Suppose you had
decided to investigate the relationship between stress at the work place and dual
career family happiness
a Since there are multiple ways to measure stress in the work place describe
two ways to do this Hint - avoid using two self-report measures
b Describe how you would decide on the best single measure In doing so
describe the steps you would take in evaluating your measure Be sure to define
your meaning of validity and reliability It is important that your measure have
all the necessary psychometric characteristics so that other scientist can trust the
results of your research
c Be certain that you answer the question Validity for what
d In order to understand the results of your study you need to compare your
measure of stress at work with other measures of this construct How would you
do that
B10 Assume that you have been hired by a national survey research company
Shash Inc to write items that will be used in a national survey of attitudes
toward capital punishment There are a number of criteria that can be used to
guide your item writing What are they Briefly describe five (5) such criteria
B11 Assume that you are going to conduct empirical research to determine the
impact of interpersonal trust on organizational decision making Describe and
justify the steps you might follow to develop an operationalization of the
interpersonal trust concept
B12 Assume that you are going to conduct empirical field research to assess the role
that employee empowerment plays in determining the level of organizational
commitment of employees Describe and justifyexplain the steps you would
follow to develop a valid and reliable operationalization of the concept of
employee empowerment
Explain the procedures and standards you would use to determine if your
operationalization is valid and reliable
How would you assess the construct validity of such a measure
Discuss issues concerning the level of observation of your measure and level of
analysis of the data
B13 Assume you are interested in developing a new scale to measure construct X
Further assume that you have used previous literature and your own conceptual
development to delineate 2 dimensions of X specifically XF1 and XF2
Describe the steps you would go through in developing testing and evaluating
this new scale With regard to testing and evaluating be sure to consider the
role of factor analysis (both exploratory and confirmatory) and item analysis
Also you will want to make sure that your new multidimensional scale shows
evidence of validity (several kinds) and reliability so be sure to examine these
issues and explain how specific information gathered from the above testing
contributes to these concerns
C) Reliability
4) What is reliability and why is it so important What are the different ways reliability can be
assessed and when is each appropriate
15) What does coefficient alpha assess What are the ways coefficient alpha can be increased
C1 Describe and discuss the concept of reliability and all of its various forms
including their assessment When is each form appropriate and what information
is provided by each index
C2 In establishing congruence between multiple measurements we often compute
indices of reliability andor indices of agreement These two types of indices
address very different questions Your task is to 1) Define reliability and
agreement 2) Explain when each is useful using examples in which one but not
the other is appropriate and 3) Briefly describe two reliability indices and two
agreement indices
C3 Explain reliability in terms of the classical test theory What are the
consequences of unreliable measures in hypothesis testing What are the factors
that may affect the reliability of a multi-item scale
IC
C4 Generalizability theory is used within IO psychology more often today
However most researchers continue to use Classical Test Theory
conceptualizations of error to determine reliability What are the implications of
using classical test theory versus generalizability theory to assess reliability
C5 In establishing congruence between measurements we often compute indices of
reliability andor agreement Define reliability and agreement Explain the
differences in reliability and agreement and describe under what conditions
assessing reliability is more appropriate and under what conditions assessing
agreement is more appropriate
C6 Define measurement reliability in terms of a specific measurement theory (eg
true test score theory domain sampling theory generalizability theory IRT)
Discuss the different approaches for estimating reliability and the contexts in
which each might be appropriate Use examples throughout
C7 What are the consequences of unreliability in a measure
C8 What are some of the conditions that might keep the internal consistency (eg
alpha) of a given measure low Is a low alpha always a sign of a problematic
measure
C9 Define reliability Name some methods of calculating reliability How well do
these methods map up with the definition of reliability What is the impact of the
number of test items and sample size on Chronbachs alpha and why would this
effect occur or not occur (Note Do NOT discuss inter-rater reliability)
C10 Schmidt and Hunter (1996) described several types of measures typically used in
organizational research and identified the type(s) of measurement error affecting
each of them in various situations For each measure below indicate the types of
error and sources of error that are most likely to affect it Then indicate what
could be done to reduce errors of measurement andor what can be done to
control for errors statistically
a Supervisor ratings of subordinates job performance
b Self-ratings of ones own job performance
c Self-reports of ones own job-related attitudes
d Sales figures for a salesperson (or production quantity for a production
worker)
d Aptitude tests taken as part of the hiring process
C11 Suppose you had conducted research on the relationship between organizational
commitment and rigidity of organizational structure in 200 firms Your measure
of rigidity was based on number of organizational authority levels and the degree
to which written organizational rules existed and defined role behaviors for
employees Thus an organization with a large number of organizational levels
and specific written policies defining appropriate role behaviors for employees
would score high on rigidity of organizational structure After analyzing your
data you find that there is a statistically significant negative correlation between
commitment and rigidity which is consistent with your hypothesis However the
reliabilities for your two measures are
(1) commitment = 23 (2) rigidity = 83
How should you interpret your results What could you do to fix this situation
Describe the specific steps (in order) you would follow to develop a more
reliable measure of commitment
C12 (a) Define the concept of reliability (of measures) in a clear concise and
accurate manner (b) Provide a formula that expresses the reliability of a measure
in terms of two components of variance ie total variance and the error
variance
D) Multi-level Assessment
D1 One of the major challenges for group-level research is the issue of aggregation of
individual data to the group level
(a) Under what conditions (eg types of data number of raters) should the various
interrater agreement and reliability methods be used (Rwg Kappa and Weighted
Kappa percent agreement average pairwise correlation ANOVA methods
(interclass correlation coefficient WABA)) What are the advantages and
disadvantages of each of the methods
(b) Explain the controversy between Frank Schmidt Larry James and others
regarding the differences between interrater agreement and interrater reliability
Who is right Do the differences matter in research practice
Defend your answers
(c) Review two articles from the organizational behavior literature that have had to
deal with aggregation issues Critique the methods the authors used to make
aggregation decisions
(d) Provide some advice to researchers regarding what they should do if interrater
agreement and reliability indices indicate that it is not legitimate to aggregate their
data
(e) Provide some ideas for avoiding the need to aggregate in group-level research
through creative research methods and measurement strategies
D2 Cross-levelmulti-level research is becoming more evident in the organizational
research literature This type of research raises many issues and presents many
challenges in terms of designing the research measuring variables and collecting
and analyzing the data Assume that you are interested in aggregating data (eg
from the individual to the group or from the firm to the industry) for one or more
variables What are the major issues you will need to deal with
D3 A researcher wants to measure organizational climate for continuous learning
Organizational climate is operationalized as a shared consensual aspect of the
organization -- the shared perception among employees that the organization values
and supports continuous learning Describe how you would measure organizational
climate in this case Specify (a) the level (ie individual group organization) at
which the construct exists (b) the level at which you would measure the construct
and (c) the procedures that you would use to establish that measurement is aligned
with theory (ie the construct validity of the measure)
E) General (Measurement)
E1 Studies in organizational behavior research often rely on single-item measures of
key constructs The use of single-item measures has long been criticized based
on the premise that single-item measures are unreliable However Wanous
(Wanous amp Hudy 2001 Wanous amp Reichers 1996 Wanous Reichers amp Hudy
1997) has recently argued that single-item measures can exhibit adequate
reliability Wanous based this conclusion on a procedure for estimating the
reliability of single-item measures using the classic formula for correction for
attenuation Subsequent studies have yielded mixed results regarding the
conclusions of Wanous (eg Loo amp Kells 1998 Nagy 2002) and the veracity
of the perspective advocated by Wanous remains in question Summarize and
assess the arguments for and against the use of single-item measures and
evaluate the procedure and evidence offered by Wanous regarding the reliability
of single-item measures Based on your assessment and evaluation develop
recommendations regarding the use of single-item measures in organizational
behavior research

E2 Ipsative measures have become prevalent in organizational behavior research
Ipsative measures ask respondents to answer questions relative to one another
such that the scores for all questions sum to the same constant for all respondents
Examples of ipsative measures include rankings Q-sorts and the allocation of a
fixed number of points (eg 100) across a set of response options Ipsative
measures may be contrasted with absolute measures which ask respondents to
answer questions independently from one another Absolute measures are
exemplified by rating scales using an interval or ratio numeric response format
The relative merits of ipsative and absolute measures have been debated for
decades (eg Cornwell amp Dunlap 1994 Hicks 1970 Johnson Wood amp
Blinkhorn 1988 Saville amp Wilson 1991 1992) yet the fundamental issues
underlying this debate have not been adequately addressed in organizational
behavior research For example measures of organizational culture and values
are often ipsative and some researchers advocate these measures over absolute
measures (eg Meglino amp Ravlin 1987 OReilly Chatman amp Caldwell 1991
Ravlin amp Meglino 1987 see also Rokeach amp Ball-Rokeach 1989) Review the
relative merits of absolute and ipsative measures Based on your review which
form of measurement is most appropriate and why Do your conclusions depend
on the construct being measured If so what types of constructs are best suited to
ipsative measures and what types are best suited to absolute measures Next
apply your conclusions to the measurement of culture and values in
organizations What specific arguments have been advanced in favor of ipsative
measures of culture and values How sound are these arguments Should ipsative
measures be used in the study of organizational culture and values If not how
can absolute measures of culture and values be developed that address the
concerns voiced by advocates of ipsative measures Provide a specific example
of the type of measure you would propose

E3 In organizational research measures often consist of items that represent different
facets of a concept Although such measures are prevalent and in some cases are
advocated (eg Law et al 1998 1999) they can present a variety of conceptual
and methodological problems Describe the specific problems associated with
measures that use items representing different facets of a concept Compare these
problems with the purported advantages of such measures Conclude by

c Qualitative field research
d Quantitative field research
E5 Suppose Roberta Von Eisenbrick is a researcher interested in the consequences of
AFFECTIVE CONFLICT (AC) in decision-making teams She gets access to a
variety of outcomes assessment committees at each of 87 different schools in
the Dallas Independent School District and gains permission to tape-record two
of their meetings (one in February and one in March) Such committees have
been formed to develop quantitative ways to track pursuit of school goals and
provide accountability to local and state governments These are often divisive
teams with heated meetings because what gets assessed is what usually gets
rewarded After both of these meetings the committee members each
fill out a short questionnaire that contains 20 Likert-type items measuring how
much AC occurred (eg People in our group often get angry with each other)
The individual scores are summed across items then averaged across team
members to come up with a group-level AC score for each of the 87 2
meetings The same procedures are followed for a 5-item measure of Group
Cohesiveness (GC) which is predicted to be reduced by higher levels of AC
Roberta also listens to every tape and from her expert judgment she rates each
groups meetings on the same 20 items Those 20 ratings are summed for each of
the 87 2 meetings Now Roberta is interested in evaluating her measure She
wants it to have excellent psychometric properties including reliability and
construct validity

things that researchers have inappropriately sanctified the p lt 05 level of
significance Describe and critique the arguments for and against the use of
statistical significance testing in empirical research What information other than

D) ModeratorsMediators
D1 Moderation and mediation provide different ways to model third variable effects
(a) Please define both of these terms (b) Sketch a conceptual model to show how
each relates to main effects (c) Using variables of your choice please write
hypotheses to reflect both (d) Explain how each is tested analytically
D2 Discuss moderators and mediators Provide an example of how (1) a moderating
variable influences the relationship between the independent and dependent
variable and how (2) a mediating variable influences the relationship between
the independent and dependent variable Describe how you would test for both
moderation and mediation using regression
D3 Many theories in organizational research predict that the effects of one variable
on another are moderated by a third variable Such moderator effects are
typically tested by entering the product of two variables as a predictor after
controlling for the two variables that constitute the product Several researchers
have pointed out that this product is often highly correlated with the squares of
the two constituent variables and have suggested that moderating effects may be
tested after controlling not only for the two constituent variables but also their
squares (eg Cortina 1993 Ganzach 1998 Lubinski amp Humphreys 1990
MacCallum amp Mar 1995) Discuss the strengths and weaknesses of this
approach as compared to methods that use only the product term and its
constituent variables Conclude with recommendations as to when and under
what conditions organizational researchers should test moderator effects with the
squares of the constituent variables in the equation

D4 Assume you are interested in studying relationships amongst three variables X
Y and Z Your first hypothesis posits Z as a mediator of the relationship between
X and Y Your second hypothesis posits Z as a moderator of the relationship
between X and Y Draw the figures depicting each of these hypothesized
relationships and describe (make sure to write regression equations) how you
would test each of these hypotheses
D5 The amount of time and effort that the average person pours into his or her job
has risen steadily over the last two decades such that the average person now is
working one more week per year than the average person in the mid 1970s This
steady increase has fueled research interest in the construct of Job Burnout (JB)
which is an emotional and physical exhaustion associated with ones work
Organizational Stress (OS) the perception of greater demands than available
resources in ones work environment is thought to be one of the chief
antecedents of JB However time spent under OS is thought to make its affects
on JB accumulate or worsen Work Role Withdrawal (WRW) the avoidance of
responsibilities or the deliberate reduction of inputs to ones job is believed to be
the chief consequence of JB
a Formally state these ideas as verbal hypotheses as equations and as a complex
directed graph (circle amp arrow diagram)
b Conceptually what is a mediator Define the term and identify the mediator in
your hypotheses in (a) What elements or steps in a study design (not statistics)
that would be helpful for detecting the mediating relationship that was proposed
c What is a moderator What are some of the other names for it within various
subdomains of management Further demonstrate your understanding of
moderator variables by picking which variable in (a) is the moderator Show the
moderating relationship in an X-Y (or multi-layered) chart Again what elements
or steps in a study design (not statistics) would be helpful for detecting the
moderating effect implied above
E) Multiple Comparisons
E1 In your role as professional colleague you are called upon to advise another doctoral
student about the appropriate use of multiple comparisons and post hoc tests in
analysis of variance Your student colleague already has been introduced to ANOVA
and multiple regression Specifically you are to write out a description of how to test
for differences among the different levels or cells of a categorical variable In your
description you should discuss among other things
a the statistical and philosophical issues raised by post hoc analysis and data
snooping
b the different multiple comparison methods commonly used by researchers to test
for differences among cell means and
c the advantages and disadvantages of each method
Note Your written description will be evaluated based on your demonstrated
competence with the statistical method not on the pedagogy of your explanation

recommendations You conduct a well-designed controlled study (details are unimportant) and discover students who use the new book perform 10 better on a standardized subject
matter exam than those using the old book (p = 027) Both books are readily availabe their prices are almost identical and both are equally acceptable to the instructors What is your recommendation to the chair
F1 Attached is the beginning of an article Your task is to write the results section by
1 making up and reporting plausible descriptive statistics that will help the
reader understand the results of the statistical tests you report and the nature of your
sample (Hint this can be presented in the form of a table)
2 describing and defending your choice of appropriate statistical tests of the
hypotheses and the steps that you would go through in carrying out these tests
3 making up and reporting results of these tests that are consistent with your
descriptive statistics and with any information in the rest of the article about the
results found (Hint this can be presented in the form of a table)
4 describing how well these results provide support for the hypotheses You
may want to note any relevant threats to validity here
Be sure to state any assumptions you make
F2 Assume that the Personnel Manager of a local firm Ms B dFlandres hired you to
analyze some data that her assistants had collected over the past several years The
data consist of (a) job performance ratings that were made in June of 1990 and (b)
scores on 25 predictor variables (eg measures of education job experience job
tenure job aptitude personality) that were measured when the individuals were hired
(between April 1987 and May 1988) She had data from only the 110 subjects (60
males and 50 females) who were hired during the period and were still employed by
the firm One objective of your analysis (analyses) is to determine how well the
performance criterion can be predicted by the predictors What strategy would you
use in analyzing the data Describeexplain (b) Is sample size an issue for your
analyses Explain If it is what will you do to deal with problems stemming from
sample size Assume that no additional data can be collected at this time (c) Some
preliminary analyses that you do reveal that five of the predictor variables correlate
(zero-order basis) about 75 with one another Will this influence the analyses that
you use Will it influence the validity of conclusions derived from your proposed
analyses (d) Ms dFlandres is interested in knowing if the predictor variables are
equally effective in predicting the job success of males and females What analysis
or analyses would you do to deal with this issue
F3 Assume that you have been provided with data on 12 conceptually distinct variables
that are moderately correlated with one another at the empirical level The data are
from students in four different college majors ie astronomy (A) biology (B)
criminology (C) and demography (D) The 12 measured variables fall into the
general categories of mental health (tension emotional withdrawal hallucinations
guilt feelings blunted affect and suspiciousness) and job satisfaction (work itself
supervision co-workers pay promotion prospects and working conditions) Your
task is to determine if the individuals in the four college majors differ from one
another on the 12 measured variables
(a) What statistical technique(s) would you use to test for group differences
Explain Be specific about the procedures(s) that you would use
(b) What statistical estimate would you use to estimate the extent to which the
groups differ from one another Be specific
F4 The following statistical table published in a recent issue of Work amp Occupations
was taken from an article discussing variables influencing resistance and citizenship
behaviors in the workplace Resistance behaviors include playing dumb withholding
effort work avoidance subverting particular managers and sabotage Citizenship
behaviors include cooperation engaging in peer training use of insider knowledge to
facilitate production commitment to organizational goals giving extra effort freely
Both measures are global constructs aggregated to the interval level and
standardized
The table reports the results of a series of ordinary least squares regression equations
with standardized coefficients Explain the meaning of the statistics presented What
do these statistics tell us generally about the relationship between resistance
behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows
Anomie Index -standardized interval level measure tapping multiple dimensions
The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)
F5 Researchers collected data from a sample of 350 companies on the following
variables
size (measured as number of employees)
Business Strategy (a nominal variable with 2 response options low-cost provider or
differentiator)
HR Strategy (a nominal variable with 2 response categories High commitment or
low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

I2 A study examined the effects of gender and pre-training motivation on the transfer of
training in terms of improved performance for 123 new industrial managers The
training was on supervisory skills and the dependent variable was based on the

J) Meta-analysis
J1 There exist two categories of literature review narrative and quantitative Each
category as typically implemented has certain advantages and disadvantages
Describe the advantages and disadvantages associated with each approach taking
particular care to enumerate the disadvantages associated with quantitative review
Then offer two ways that meta-analysis might be combined with other analytical
techniques to move beyond the focus of bivariate relationships that is typical of meta-
analysis
J2 Schmidt has argued that primary research does not allow one to discover general
scientific laws but that meta-analytic research does What are the arguments in favor
of or against this position In what areas of research (if any) has Schmidts
prediction come closest to coming true
J3 The so-called (by Hunter Schmidt and Jackson 1983) state of the art meta-
analysis method attempts to account for various sources of error that might produce
apparent variation in effect sizes across studies (a) Discuss the three most important
sources of error that meta-analysis addresses (b) Discuss the potential contribution
that a meta-analysis can make to theory building in the organizational sciences (c)
Describe the circumstances that you would consider when deciding whether to
perform a meta-analysis
J4 Meta-analysis has been hailed as a miracle cure and criticized as smoke and
mirrors Explain both sides of the debate and then lay out the role of meta-analysis
as you see it within the time span of your career as an academic To do this use
examples of already written (or yet to be written) articles as models
J5 A frequent criticism of non-quantitative research summaries (literature reviews) is
that researchers do not carefully examine how particular research designs might have
affected the statistical outcomes of the studies included in the literature review Meta-
analysis however allows one to statistically examine such effects Assume you are
conducting a meta-analysis of the relationship between leader behaviors and group
productivity Briefly describe the steps you would take in conducting a meta-
analysis What aspects of the original research designs would you examine in your
meta-analysis What steps would you take in gathering and coding data to enhance
the credibility of your analysis
K) MTMM
K1 One method often used by social scientists to demonstrate the construct validity of
measures is the multi-trait multi-method matrix developed by Campbell and
Fiske (1959) Briefly describe how this matrix is obtained or constructed by a

model For each of those three statistical procedures describe and discuss the
following
a The type of data necessary for using the technique appropriately

What is the role of theory in the two factor analyses
IC
O2 Compare and contrast Exploratory Factor Analysis (EFA) with Confirmatory TH

assumptions usage and limitations
O3 How do exploratory and confirmatory factor analysis differ What are the
advantages and disadvantages of each
O4 Describe the differences between exploratory factor analysis (EFA) and
confirmatory factor analysis (CFA) When would you use one verses another
Are there ways to use EFA in a confirmatory way Can you use CFA in an
exploratory way Also describe the difference in principal components analysis
(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression

P) Structural Equation Models
P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

parameter estimate bias in structural equation modeling Structural Equation

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)
Please comment on these restrictions versus access argument Which side do you
take
What are the strengths of SEM Give some examples
What are the weaknesses of SEM Give some examples

environmental munificence or growth need strength) Give the prevailing verbal
definition of the construct and analyze the measurement controversy from two
broad angles First discuss how the controversy may or may not stem from claims
about how one measure is better or worse than another because it (or the other) is an
(a) archival record (b) direct observation (c) social report or (d) self-report That is
what are the relative strengths and weaknesses of each of these types of
measurement for the construct youre discussing Second discuss the construct
validity of the most commonly used measure(s) of this construct To answer this
second part you need to discuss just what construct validity is and how it can or
cannot be demonstrated In the situation you describe what could be done to
demonstrate or improve the construct validity of existing measures
K4 Interviewing in some form has been the workhorse for data collection in a variety
of research traditions positivistquantitative ethnographic feministpost-modernist
and increasingly historical research While each tradition elicits information from
respondents the goals and processes involved in interviewing vary considerably
across research traditions Discuss the purposes of the interview the relationship
between data and theory the roles assumed by the interviewer and the respondent
and the relevant criteria for assessing the validity and reliability of the information
obtained In addition compare and contrast the use of the interview as a data
collection method in the positivistquantitative tradition with its use in one of the
alternative traditions
L) Common Method Variance
L1 Many of us have had concerns about the reviews of our survey research which
suggest that data analyses of surveys are biased because of common method
variance effects of individual differences such as negative mood negative
affectivity and social desirability and the reliability and validity of the constructs
we are attempting to measure Define how these problems affect a research issue in
organizational behavior and the steps that might be taken to minimize such potential
criticisms of papers based on analyses of self-reported data through survey
instruments
L2 In a series of papers by Spector (1994) Schmitt (1994) and Howard (1994)
published in the Journal of Organizational Behavior arguments were provided for
and against the use of self-report questionnaire measures One of the issues
discussed that could limit conclusions drawn from relationships observed using self-
report measures was method variance What is meant by method variance what are
its sources and what impact is it expected to have on research findings
M) Sampling
M1 The manufacturing census samples all plants of 250 employees or more For
plants of 5-249 employees it takes a size proportional sample Plants of 1-4
employees are not sampled What challenges does this sampling method provide
to researchers What could you do to account for these problems if you were
TH
studying organizational (not plant) growth
M2 New York State has approximately 250000 employees in over 70 state agencies
commissions and boards ranging in size from approximately 50 to over 5000
employees Assume that you wanted to draw a representative sample of 1000
employees Describe two ways that you could draw such a sample and briefly
describe the advantages and disadvantages of each of these sampling approaches
IC
M3 The director of a national non-profit agency with approximately 10000
employees located primarily in regional offices in each of the 50 states the
United States has approached you and asked you to develop a study
(organizational survey) of organizational culture within the agency The agency
is about to embark on a variety of change initiatives including developing team
structures and the study is meant to examine various elements of organizational
culture that are potential barriers to change The director has indicated that he
would like to have the data analyzed at both the individual and office level of
analysis Because of funding limitations the agency will only be able to send the
survey to 1000 employees The director has indicated that there are three ways
of sorting employees all employees listed alphabetically all employees listed
alphabetically by state and all employees listed alphabetically by region (there
are between five and ten regions per state) Given these three ways of sorting
employees describe at least three different sampling approaches and the
advantages and disadvantages of each
M4 In your role as Teacher of Organizational Studies you are asked to prepare a
tutorial for beginning doctoral students on sampling design Assume that this
tutorial is part of a basic class in research design and that students in this class
have had a basic statistics course up to and including multiple regression Your
tutorial should focus on briefly defining and explaining the differences between
probability and non-probability samples You should make sure to present and
describe several types of probability samples (eg random systematic
stratified etc) and non-probability samples (eg convenience snow-ball quota
etc) and discuss general principles for when to use a probability vs a non-
probability sampling design For each sampling design you should also provide
at least one clear example of a situation where this type of sampling design is
appropriate
N) Cross-Cultural Research
N1 Discuss the problems in conducting cross-culturalnational comparison in terms
of (1) conceptualization and (2) research design and data collection
Define the three levels of measurement invariance How would the problems that
you have identified in part (a) affect measurement invariance How would you
examine measurement invariance by confirmatory factor analysis
TH
N2 Explain why using national boundaries as independent variable in cross-cultural
studies may not be appropriate in terms of theory and research methods What
alternative ways would you recommend
IC
O) General
O1 In your readings research has been described as choices among conflicting goals
(desiderata) For instance when choosing among research strategies a researcher
must choose among the desiderata of precision realism and generalizability The
trade-offs among desiderata occur for all aspects of research that is for the selection
of theories the treatment of independent variables research strategies the selection
of the problem to study rules of evidence for determining the meaningfulness of a
research finding and even the frameworks that describe the research process
Discuss what you see as the major trade-offs for each of the following aspects of
research That is discuss what you see as the major strengths and weaknesses
(advantages and disadvantages) of each aspect
a The trade-offs between internal and external validity
b The manipulation of the independent variable vs the observation of the
independent variable
c Basic vs applied research
3 DESIGNING A RESEARCH STUDY
A) General (Research Design)
3) Why is control so important in research design What are the different ways it can be
achieved (give a brief description of each control method) What are advantages and
disadvantages of each
A1 It has become almost a truism to note that the choice of methods influences theory
and questions data and conclusions (the causal direction might also be reversed)
Briefly discuss how the methods used have influenced research in any two of the
following areas leadership power and politics organization culture organization
justice Compare and contrast as possible Suggest some potentially fruitful
methodological directions for future work in these same topical areas and dont be
shy about reflecting on broader issues of how the field of organizational behavior
constructs its realities Lastly tie your discussion and reflections back to your own
future as a researcher what lessons or guidance do you derive from your
understanding of these issues
A2 Characterize as fully as possible what you see to be the methodological approach or
approaches in strategic management research Is there a dominant method or a wide
variety Discuss the reasons for the situation What are the advantages benefits etc
of the approach(es) in use What assumptions (ontological epistemological
ideological) do they embody Are current efforts ideal or at least adequate Are
there other approaches that could be useful If so how might researchers be
encouraged to use these as well If you see no advantage to more variety in
methodological approach support that point of view
A3 Describe a research question or area of interest to you and why you think it is not
only of interest but significance Using your understanding of research methodology
describe two ways of pursing the question that are as divergent on as many
dimensions as you can imagine Describe the advantages and disadvantages of each
approach How strong a link or fit is there between a research question and a
method
A4 In his 1957 article entitled The two disciplines of scientific psychology Cronbach
discussed the assumptions goals and methods used in experimental methods and
correlational methods in psychology
a According to Cronbach what is the main difference between the two disciplines
b Discuss the strength and weaknesses of each discipline
c What if anything could be done to improve the situation
B) Designing a Research Study
B1 Cook and Campbell describe the experiment as the research design with the
greatest methodological rigor However given the constraints present in most
organizations I-O Psychologists cannot often conduct experiments in applied
settings and must settle for techniques with less control than experiments
Describe a study to investigate the relationship between participation in a
supervisor training program and work performance which could realistically be
conducted in an organization If an experiment is not possible describe how you
would go about maximizing your ability to draw valid conclusions from your
design
B2 The XYZ Co has recently developed a sexual harassment web-based training
program The developers claim the program will cut training time and costs and
will be as effective or more effective than classroom-based sessions They
believe that this will be due to the increased availability of the program and the
ability for participants to review program material on demand Before the XYZ
Co developers launch this product they want you to determine if their claims
have merit Explain how you would design a study for this purpose
B3 Research suggests that demographic diversity improves group creativity but
reduces group efficiency Some argue that demographic diversity is just a proxy
for value and experience diversity and that demographic diversity on its own is
meaningless Design a test to settle this argument
TH
B4 E-mail has become a common form of communication in organizations and is
used for both formal and informal communication Because it has become so
IC
popular some people complain that the frequent use of e-mail leads to
miscommunication because they receive communications in e-mail that should
be accomplished through face-to-face or telephone conversations where there is
an opportunity for interaction You are interested in looking at this
phenomenon You are most interested in describing how e-mail is used for both
formal and informal communication and in examining the effect of the e-mail
use on organizational communication effectiveness Design empirical research
to address those issues
Describe your study in detail thoroughly explaining the research design
sampling plan data collection procedures ethical issues and proposed data
analysis for your research design Be sure to discuss the internal and external
validity of your research Which validity threats are ruled out and which
remain
REMEMBER Be thorough Your research design should demonstrate that you
are a competent researcher who is knowledgeable about the proposed research
methodology or methodologies Therefore be sure that you carefully describe
and give technical explanations for each component of your research
B5 Choose a specific situation involving employee selection eg artists for an
advertising agency (a) What strategy would you use in selecting the selection
measures (b) How would you combine the measures eg which measures
would you combine in a compensatory manner and which is a noncompensatory
manner (c) How would you assume test fairness defining various measures of
the term (d) How would you make final selections (e) How would you
validate your procedure (f) What considerations would enter in if your
company were too small to provide validation data (g) What difference would
it make if you were developing a procedure for deciding whether trainees
should be promoted as opposed to making new hires Please note--emphasize
but do not limit yourself to statistical issues
B6 There is evidence in the marketing literature of a non-monotonic relationship
between the expectations that customers have for retail service and their
eventual level of satisfaction with that service That is as a customers
expectations for service increase so does their eventual service satisfaction --
up to a point After that point the greater the expectations the lower the
eventual satisfaction Develop a hypothesis that includes a moderator variable
that might account for this evidence Give some reasonable rationale for it State
your hypothesis verbally as an equation as a directed graph (circle amp arrow
diagram) and as an X-Y function chart Discuss how it would or would not be
possible or useful to test your hypothesis via a laboratory experiment In your
discussion cover how and why a researcher could (not) manipulate the
independent constructs involved (mode X) whether or not random assignment
to conditions (mode R) is possible (including how may conditions would be
necessary) which alternative constructs could or could not be controlled (mode
K) and which constructs should be measured (mode Y)
B7 Assume you are the chairperson of a committee that must evaluate
undergraduate programs at your university Your task as chairperson is to
devise an approach (a design a research strategy a set of measures) that will
allow you to evaluate undergraduate programs Make sure that your approach
can be used in the future and at other comparable universities When developing
your plan be sure to address at least the following issues
a the type of design you would select Compare and contrast the selected design
with another possible design
b the type of research strategy you would select Compare and contrast with
another possible strategies
c discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
B8 Assume you are an organizational research design expert assigned to the
Strategic Planning Department of a large multi-national manufacturing firm
The Department has developed a new PC-based software package called
STRATPACK The software (and a one-week training course to learn how to
use it) is intended to improve the long-range planning ability of middle and
upper-level managers
Your job as research design expert is to devise research (a design a research
strategy a set of measures) that will allow you to evaluate the effectiveness of
the STRATPACK program Describe a research design for evaluating the
program Make sure that your research approach can be used in the future and at
all sites in the company When developing your plan be sure to address at least
the following issues
a discuss how your design and approach deals with the major forms of validity

independent variable versus observe the independent variable) Compare and
contrast the selected design with another possible design
c how your design deals with the major forms of validity Be sure to examine at
least internal external and construct validity
B9 Assume you are a consultant hired to evaluate the effectiveness of an industrial
safety program undertaken by a large manufacturing organization The safety
program is a behavioral one that provides rewards such as monetary bonuses or
extra paid vacation days for safety behaviors in terms of accident-free days
weeks etc Your task is to devise an approach (a research strategy a design a
set of measures and a general analysis strategy) that will allow you to evaluate
the safety program Because of the potential for the influence of many
extraneous variables on any safety program it is difficult to design research a
single cross-sectional study than can evaluate the impact of a single safety
program How would you design a study to evaluate the impact of the safety
program When developing your plan be sure to address at least the following
issues
a the type of research strategy you would select Compare and contrast with
another possible strategies
b the type of design you would select Compare and contrast the selected design
with another possible design
c discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
B10 One of the most important areas of research is forecasting of human resources
needs based on strategic positions of organizations For example NY State must
carefully forecast its human resources needs as it proceeds with significant lay-
offs of state employees Future human resources needs are generally evaluated
by either statistical ie regression or simulation or clinical judgment i e
supervisors judgments methods
a Design a single study that addresses the empirical question of whether
statistical or judgmental methods are better for forecasting human resources
needs You may discuss a program of research but please be quite specific in
your description of the first study
b What are the critical methodological issues in doing this kind of research
c What are the critical applied (or practical) issues in doing this research
d Are the issues in b and c related
B11 In the past decade computinginformation technology has changed many
aspects of organizational life For example the technology can make increased
decentralization possible by improving communication between central offices
and field offices Computer networks and word processors can enhance group
empowerment by making it possible for team members to create and edit
written group products quickly even if the individuals are at different locations
Some have argued that computinginformation technology will foster the
paperless productive office nevertheless others argue that the technology only
increases paper and reduces office productivity You are applying to the
National Science Foundation for a grant to conduct research that examines the
impact of computing information technology on organizational decision
processes The NSF application procedure imposes five basic requirements that
your research design must fulfill in order to receive funding Note A very
significant factor affecting NSF grant decisions is a clear demonstration that the
researcher is knowledgeable about the research methodology used Write your
response to each of the following five grant requirements Be sure not only to
respond to the requirement but also to demonstrate your research
competence
1You must design a study that uses two different methods
(interviewobservation survey experiment or quasi-experiment) Describe your
two methods in detail and provide a rationale for the key elements (eg
sampling data collection proposed analysis) of your methods Be sure to
discuss and evaluate the internal and external validity of both methods
2 As part of your research design you must select a conceptual (latent) variable
central to your proposal (use centralization of decision making as your
variable) and describe how you will develop your own measure (You may not
simply use off the shelf instruments)
3 You must describe how you will test for the reliability of the measure
(centralization of decision making) you developed in step 2 The NSF insists
that you describe how you will evaluate both the temporal stability and the
internal consistency of your measure Be sure to discuss what temporal stability
and internal reliability mean and how they are related
4You must describe how you will assess the validity of the measure
(centralization of decision making) you developed in step 2
5 NSF requires a brief statement and defense of the philosophy of science
underlying your research Discuss your position and show how your research
design is consistent with your philosophy
B12 Many organizations in the United States economy have installed some form of
Empowered Teams as an alternative or supplement to traditional bureaucratic
structure Preliminary evidence of the effectiveness of empowered teams
however is mixed--some organizations have claimed success and others have
reported failures The evidence however is predominantly anecdotal--written
for trade magazines by the organizations themselves There are few rigorous
empirical studies assessing the effectiveness of empowered or self-managed
teams You are applying to the United States Department of Labor (USDOL) for
a grant to conduct research that examines the effectiveness of empowered
teams The application procedure of the USDOL imposes three requirements
that your research design must fulfill in order to receive funding Write your
response to each of the three grant requirements The importance of each section
is implied by the evaluation points allocated by the USDOL to each of the three
requirements given in parentheses
1 (50 points) Your study design for assessing Empowered Team effectiveness
must use two different methods (interview observation archival analysis
survey simulation experiment or quasi-experiment) Describe in detail and
thoroughly explain the sampling plan instrumentation data collection
procedures and proposed data analyses for both methods Be sure to discuss the
internal and external validity of both methods and how the two methods
complement one another
2 (30 points) As part of your research design you must select one conceptual
(latent) variable central to your proposal and describe how you will develop
your own operationalization of the measure (You may not simply use off the
shelf instruments) Use the concept of group morale to demonstrate your
operationalization methodology Be sure to explain very explicitly to the
USDOL how you will assess the validity and reliability of the group morale
measure you are developing
3 (20 points) The USDOL traditionally has funded research conducted only
within the general paradigm of logical positivism but now is more open to other
research paradigms as well Your grant proposal must provide a statement and
defense of the explicit philosophy of science underlying your research Describe
your philosophy of science and show how your research design is consistent
with your philosophy
REMEMBER Be thorough You not only must design effective research but
you also must demonstrate to the USDOL that you are a competent researcher
It is absolutely vital to the USDOL that the principal researcher is
knowledgeable about the proposed research methodologies Therefore be sure
that you always carefully describe and give technical explanations for each
component of your research design and explain all technical terms (eg
Cronbach alpha KR-20 Likert scale)
B13 Assume that you are working as part of a research team that is responding to a
RFP (Request for Proposals) from a funding agency for research on work
socialization and newcomer adjustment The RFP calls for rigorous field
research that tests the effectiveness of theory-based interventions aimed at
facilitating the adjustment of new organizational members to complex andor
stressful work conditions The major goal of your teams research is to test the
effectiveness of a self-regulation intervention which trains newcomers to
identify and use relevant social information and cues to regulate work behavior
Your group hypothesizes that self-regulation training will be more effective
than other common treatments or interventions (eg realistic job previews
institutionalized socialization tactics)
You have been included in the team because of your methodological expertise
Your role is to design a rigorous field experiment or quasi-experiment to test he
effectiveness of the self-regulation training program REMEMBER THE
MAJOR CRITERION FOR FUNDING IS THE RIGOR OF THE RESEARCH
DESIGN Design a field study to include in the grant proposal Your proposal
should contain the following two sections
1 Study Design Construct and describe in detail an experimental or quasi-
experimental design to test the effectiveness of your intervention Describe in
detail the experimental groups (including how they will be constructed) the
research setting the sampling plan for study participants the treatment
manipulation and the data collection procedures Also indicate any control or
nuisance variables that may be measured
After describing the procedures write a justification of the design What threats
to validity does it rule out or limit and what threats to validity remain
II Measurement Describe the steps you would take to achieve valid and
reliable measure of the latent (conceptual) variable worker adjustment Your
team feels that as part of the proposal you must develop an original
operationalization of adjustment (thus you cannot simply use existing off the
shelf measures) Indicate in adequate detail how you would operationalize the
measure and indicate how you would demonstrate reliability and validity
B14 In describing their notion of the collective mind Karl E Weick and Karlene H
Roberts note Our focus is at once on individuals and the collective since only
individuals can contribute to a collective mind but a collective mind is distinct
from an individual because it inheres in the pattern of interrelated activities
among many people (p 360) Collective mind is not indexed by within-group
similarity of attitudes ideas or activities A collective mind is one in which
many people or many groups integrate their different attitudes ideas and
activities heedfully As Weick and Roberts note People act heedfully when
they act more or less carefully critically consistently purposefully attentively
studiously vigilantly conscientiously pertinaciously (p 361)
The idea of the collective mind as heedful interrelating is developed in the
following excerpt When people make efforts to interrelate these efforts can
range from heedful to heedless The more heed reflected in a pattern of
interrelations the more developed the collective mind and the greater the
capability to comprehend unexpected events that evolve rapidly in unexpected
ways When we say that a collective mind comprehends unexpected events we
mean that heedful interrelating connects sufficient know-how to meet situational
demands For organizations concerned with reliability those developments
often consist of unexpected non-sequential interaction (p366)
An example of heedful interrelating occurs as a pilot lands herhis aircraft on the
deck of an aircraft carrier The pilot does not actually land She is recovered
A recovery is an interrelated set of activities among air traffic controllers
landing signal officers the control tower navigators deck hands the helmsman
driving the ship etc These activities can be interrelated more or less heedfully
depending on the care with which the different units contribute represent the
situation and subordinate their activities to the single purpose of successful
recovery (p 363)
You are to design a two-part study
Part I You are to design a measurement study which assesses heedful
interrelating (ie collective mind) with a quantitative measure in a replication
of an aircraft carrier flight deck or other situation of your choosing Describe
your research strategies including operationalization of the variable selection of
the sample subjects data collection data analysis and so on for the purpose of
developing a measure of heedful interrelating
Part II Using the measurement tool developed in Part I and any other tools as
needed describe how you would design a study which would compare heedful
interrelating across organizations Choose at least one macro-organizational
variable (eg technology environment) as your basis of comparison Here you
must describe how you would make your selection of organizations to be
compared your data collection procedure data analysis and so on
B15 Many organizations in the United States have installed cross-functional teams to
counteract the silo mentality of traditional bureaucratic structure Preliminary
evidence of the effectiveness of cross-functional teams however is mixed --
some organizations have claimed success and others have reported failures The
evidence moreover is predominantly anecdotal--written for trade magazines by
the organizations themselves Since there have been few rigorous empirical
field studies assessing the effectiveness of cross functional teams the National
Science Foundation has decided to fund research on the topic
Assume that you are submitting a research proposal to NSF for a grant to
research the effectiveness of cross-functional teams Describe in detail and
thoroughly explain the research design sampling plan data collection
procedures ethical issues and proposed data analysis for your research design

validity threats are ruled out and which remain NSF also requires that you
provide a statement and defense of the explicit philosophy of science underlying
your research Describe your philosophy of science and discuss how your
research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but
you must also demonstrate to NSF that you are a competent researcher It is
absolutely vital to NSF that the principal researcher (you) is knowledgeable
about the proposed research methodologies Therefore be sure that you always
carefully describe and give technical explanations for each component of your
research design and explain all technical terms (eg Cronbach alpha KR-20
Likert scale)
B16 Assume that you are submitting a research proposal to the Department of
Commerce (DoC) for a grant to research the effectiveness of virtual work teams

internet media such as a listserver or Lotus notes The DoC requires that the
researcher use both qualitative and quantitative methods to gather data Describe
in detail and thoroughly explain the research design sampling plan data
collection procedures ethical issues and proposed data analysis for your
research design Be sure to discuss the internal and external validity of your
research Which validity threats are ruled out and which remain The DoC also
requires that you provide a statement and defense of the explicit philosophy of
science underlying your research Describe your philosophy of science and

5 MEASUREMENT
A) Measurement Terms
A1 There are four levels of measurement rigor in management research Discuss each
one What properties do measurements at each level have (ie how much
information do the numbers from each level of measurement convey) How can the
numbers be changed (transformed) and still retain the properties of their
measurement level Pick one construct from a favorite research domain and give an
example of an operationalization of that construct at each of the four levels of
measurement rigor (provide arguments about why you think those examples reflect
each level) Lastly treat each examplelevel as a dependent variable in some
statistical analysis Given an example of a statistical technique appropriate for
analyzing data at that level of measurement rigor
A2 Define (and discuss important features or issues concerning) the following
constructs measurement (Define any six terms)
1 Construct validity 6 Item analysis

estate agents self-assessment of performance Since there is no existing
measurement available you have to develop the instrument by yourself
Describe how you would develop the measurement assuming that you have no
idea of how many dimension the construct has
b) Suppose you have developed an instrument consists of 20 questions
measuring 4 dimensions (5 items per dimension) from (a) You collected data
from another 300 real estate agents to validate your instrument Explain how
TH
you would use structural equations model (SEM) to examine the reliability and
validity of the instrument What are other concerns about reliability and validity
that are not addressed by this approach
B2 The research and business world have been fascinated with the concept of
organizational culture However operationalizing this construct has been a
difficult task Discuss the ways in which the construct has been operationalized
(eg technique static v dynamic sample selection generalizability) Critically
analyze each of these methodologies Then choose a methodology you would
use to examine organizational culture and defend your choice Describe how
you would study culture and what more would be known about culture as a
result of your study
B3 Suppose you are setting out to develop a new measure of a construct You want
this measure to be used in survey research and you want to establish its validity
and reliability Your goal is to have at the end of the process a measure that is
defensible and likely to be widely accepted by other researchers studying that
construct What steps would you take to conduct such a program of research
For each step explain the purpose of that step explain why that step is
important explain what methods and statistical procedures you would employ at
each step and explain what evidence you would hope to gather at each step
B4 Assume you are interested in constructing a new measure of (fill in with a
relevant variable from your field) Detail the major concerns that need to be
addressed and the steps that need to be taken in working toward validating this
new measure
B5 Assume that you recently read an article on workplace violence which you
found very interesting The authors argued that one of the predictors of
workplace violence was a construct called propensity to be violent and used a
one-item measure as follows How likely are you to become violent when
provoked You had serious doubts about the authors measure and decided to
develop your own
(a) How would you go about developing items to measure propensity to be
violent
(b) How would you determine whether the instrument was reliable
How would you determine whether the instrument was valid
B6 A concern in organizations is retirement of baby boomers within the next 5 -
10 years This concern is focused on the loss of older employees with skills
critical to the core business functions of organizations In order to continue to
have employees with those critical skills it seems necessary to retrain some
older workers However past practice in most organizations has been not to
retrain older workers for a variety of reasons mostly financial A researcher
working for the Human Resources Department of a large corporation - 13500
employees in 12 different plant locations - hypothesizes that the major reason
for not retraining older workers is ingrained in the culture of the corporation
IC
The researcher feels that older workers are not as highly valued as younger
workers in terms of their potential usefulness after retraining The researcher
searched the literature but found nothing in the existing literature to measure
the cultural value construct What should the researcher do to establish a reliable
and valid self-administered paper and pencil measure of this construct namely
the value of retraining older workers

of the concept of technological complexity What standards would you use to
determine if your operationalization is valid
B8 Organizational researchers have several strategies available to them for
gathering information (eg self-report measures archival measures direct
observation and trace measures) Assume that you are going to conduct
empirical research to assess the role that the structure of the organization plays
in determining the level of organizational effectiveness Briefly review the
strengths and weaknesses of the basic strategies (that is self-report measures
archival measures direct observation and trace measures) for measuring
organizational effectiveness Next describe and justify the steps you would
take to develop an operationalization of the concept of organizational
effectiveness What standards and procedures would you use to determine if
your operationalization is valid
B9 One of the most important topics of recent research has been stress in the work
place One of the most important problems with understanding this literature is
the varying definitions and measurement of this construct Suppose you had
decided to investigate the relationship between stress at the work place and dual
career family happiness

two ways to do this Hint - avoid using two self-report measures
b Describe how you would decide on the best single measure In doing so
describe the steps you would take in evaluating your measure Be sure to define
your meaning of validity and reliability It is important that your measure have
all the necessary psychometric characteristics so that other scientist can trust the
results of your research
c Be certain that you answer the question Validity for what
d In order to understand the results of your study you need to compare your
measure of stress at work with other measures of this construct How would you
do that
B10 Assume that you have been hired by a national survey research company

impact of interpersonal trust on organizational decision making Describe and
justify the steps you might follow to develop an operationalization of the
interpersonal trust concept

operationalization is valid and reliable
How would you assess the construct validity of such a measure
Discuss issues concerning the level of observation of your measure and level of
analysis of the data
B13 Assume you are interested in developing a new scale to measure construct X
Further assume that you have used previous literature and your own conceptual
development to delineate 2 dimensions of X specifically XF1 and XF2
Describe the steps you would go through in developing testing and evaluating
this new scale With regard to testing and evaluating be sure to consider the
role of factor analysis (both exploratory and confirmatory) and item analysis
Also you will want to make sure that your new multidimensional scale shows
evidence of validity (several kinds) and reliability so be sure to examine these
issues and explain how specific information gathered from the above testing
contributes to these concerns
C) Reliability

assessed and when is each appropriate
15) What does coefficient alpha assess What are the ways coefficient alpha can be increased
C1 Describe and discuss the concept of reliability and all of its various forms
including their assessment When is each form appropriate and what information
is provided by each index
C2 In establishing congruence between multiple measurements we often compute
indices of reliability andor indices of agreement These two types of indices
address very different questions Your task is to 1) Define reliability and
agreement 2) Explain when each is useful using examples in which one but not
the other is appropriate and 3) Briefly describe two reliability indices and two
agreement indices

C8 What are some of the conditions that might keep the internal consistency (eg
alpha) of a given measure low Is a low alpha always a sign of a problematic
measure
C9 Define reliability Name some methods of calculating reliability How well do
these methods map up with the definition of reliability What is the impact of the
number of test items and sample size on Chronbachs alpha and why would this
effect occur or not occur (Note Do NOT discuss inter-rater reliability)
C10 Schmidt and Hunter (1996) described several types of measures typically used in
organizational research and identified the type(s) of measurement error affecting
each of them in various situations For each measure below indicate the types of
error and sources of error that are most likely to affect it Then indicate what
could be done to reduce errors of measurement andor what can be done to
control for errors statistically

b Self-ratings of ones own job performance
c Self-reports of ones own job-related attitudes
d Sales figures for a salesperson (or production quantity for a production
worker)
d Aptitude tests taken as part of the hiring process
C11 Suppose you had conducted research on the relationship between organizational
commitment and rigidity of organizational structure in 200 firms Your measure
of rigidity was based on number of organizational authority levels and the degree
to which written organizational rules existed and defined role behaviors for
employees Thus an organization with a large number of organizational levels
and specific written policies defining appropriate role behaviors for employees
would score high on rigidity of organizational structure After analyzing your
data you find that there is a statistically significant negative correlation between
commitment and rigidity which is consistent with your hypothesis However the
reliabilities for your two measures are
(1) commitment = 23 (2) rigidity = 83
How should you interpret your results What could you do to fix this situation
Describe the specific steps (in order) you would follow to develop a more
reliable measure of commitment
C12 (a) Define the concept of reliability (of measures) in a clear concise and
accurate manner (b) Provide a formula that expresses the reliability of a measure
in terms of two components of variance ie total variance and the error
variance
D) Multi-level Assessment
D1 One of the major challenges for group-level research is the issue of aggregation of
individual data to the group level

interrater agreement and reliability methods be used (Rwg Kappa and Weighted
Kappa percent agreement average pairwise correlation ANOVA methods
(interclass correlation coefficient WABA)) What are the advantages and
disadvantages of each of the methods
(b) Explain the controversy between Frank Schmidt Larry James and others
regarding the differences between interrater agreement and interrater reliability

deal with aggregation issues Critique the methods the authors used to make
aggregation decisions
(d) Provide some advice to researchers regarding what they should do if interrater
agreement and reliability indices indicate that it is not legitimate to aggregate their
data
(e) Provide some ideas for avoiding the need to aggregate in group-level research
through creative research methods and measurement strategies
D2 Cross-levelmulti-level research is becoming more evident in the organizational
research literature This type of research raises many issues and presents many
challenges in terms of designing the research measuring variables and collecting
and analyzing the data Assume that you are interested in aggregating data (eg
from the individual to the group or from the firm to the industry) for one or more
variables What are the major issues you will need to deal with
D3 A researcher wants to measure organizational climate for continuous learning
Organizational climate is operationalized as a shared consensual aspect of the
organization -- the shared perception among employees that the organization values
and supports continuous learning Describe how you would measure organizational
climate in this case Specify (a) the level (ie individual group organization) at
which the construct exists (b) the level at which you would measure the construct
and (c) the procedures that you would use to establish that measurement is aligned
with theory (ie the construct validity of the measure)
E) General (Measurement)
E1 Studies in organizational behavior research often rely on single-item measures of
key constructs The use of single-item measures has long been criticized based
on the premise that single-item measures are unreliable However Wanous
(Wanous amp Hudy 2001 Wanous amp Reichers 1996 Wanous Reichers amp Hudy
1997) has recently argued that single-item measures can exhibit adequate
reliability Wanous based this conclusion on a procedure for estimating the
reliability of single-item measures using the classic formula for correction for
attenuation Subsequent studies have yielded mixed results regarding the
conclusions of Wanous (eg Loo amp Kells 1998 Nagy 2002) and the veracity
of the perspective advocated by Wanous remains in question Summarize and
assess the arguments for and against the use of single-item measures and
evaluate the procedure and evidence offered by Wanous regarding the reliability
of single-item measures Based on your assessment and evaluation develop
recommendations regarding the use of single-item measures in organizational
behavior research

E2 Ipsative measures have become prevalent in organizational behavior research
Ipsative measures ask respondents to answer questions relative to one another
such that the scores for all questions sum to the same constant for all respondents
Examples of ipsative measures include rankings Q-sorts and the allocation of a
fixed number of points (eg 100) across a set of response options Ipsative
measures may be contrasted with absolute measures which ask respondents to
answer questions independently from one another Absolute measures are
exemplified by rating scales using an interval or ratio numeric response format
The relative merits of ipsative and absolute measures have been debated for
decades (eg Cornwell amp Dunlap 1994 Hicks 1970 Johnson Wood amp
Blinkhorn 1988 Saville amp Wilson 1991 1992) yet the fundamental issues
underlying this debate have not been adequately addressed in organizational
behavior research For example measures of organizational culture and values
are often ipsative and some researchers advocate these measures over absolute
measures (eg Meglino amp Ravlin 1987 OReilly Chatman amp Caldwell 1991
Ravlin amp Meglino 1987 see also Rokeach amp Ball-Rokeach 1989) Review the
relative merits of absolute and ipsative measures Based on your review which
form of measurement is most appropriate and why Do your conclusions depend
on the construct being measured If so what types of constructs are best suited to
ipsative measures and what types are best suited to absolute measures Next
apply your conclusions to the measurement of culture and values in
organizations What specific arguments have been advanced in favor of ipsative
measures of culture and values How sound are these arguments Should ipsative
measures be used in the study of organizational culture and values If not how
can absolute measures of culture and values be developed that address the
concerns voiced by advocates of ipsative measures Provide a specific example
of the type of measure you would propose

facets of a concept Although such measures are prevalent and in some cases are
advocated (eg Law et al 1998 1999) they can present a variety of conceptual
and methodological problems Describe the specific problems associated with
measures that use items representing different facets of a concept Compare these
problems with the purported advantages of such measures Conclude by

E5 Suppose Roberta Von Eisenbrick is a researcher interested in the consequences of
AFFECTIVE CONFLICT (AC) in decision-making teams She gets access to a
variety of outcomes assessment committees at each of 87 different schools in
the Dallas Independent School District and gains permission to tape-record two
of their meetings (one in February and one in March) Such committees have
been formed to develop quantitative ways to track pursuit of school goals and
provide accountability to local and state governments These are often divisive
teams with heated meetings because what gets assessed is what usually gets
rewarded After both of these meetings the committee members each
fill out a short questionnaire that contains 20 Likert-type items measuring how
much AC occurred (eg People in our group often get angry with each other)
The individual scores are summed across items then averaged across team
members to come up with a group-level AC score for each of the 87 2
meetings The same procedures are followed for a 5-item measure of Group
Cohesiveness (GC) which is predicted to be reduced by higher levels of AC
Roberta also listens to every tape and from her expert judgment she rates each
groups meetings on the same 20 items Those 20 ratings are summed for each of
the 87 2 meetings Now Roberta is interested in evaluating her measure She
wants it to have excellent psychometric properties including reliability and
construct validity

it
c What is construct validity Discuss how the (un)reliability of the AC measure
could affect the conclusions one would draw from a study involving it and GC In
your discussion be sure to go over the connection between reliability and
validity and the connection between reliability and the probability of Type I or
Type II statistical errors

C) Statistical Conclusion Validity
C1 Assume you have hypothesized a relationship between variables X and Y conducted
a study to investigate this relationship and found it to be statistically non significant
What are the various reasons that might explain why the X-Y relationship was not
significant
C2 What is statistical conclusion validity and what factors affect it Indicate the nature
of the effect on statistical conclusion validity of each factor you mention What can
researchers do to improve statistical conclusion validity
C3 In general what canshould a researcher do to maximize the likelihood that his or
her statistical conclusions will be valid Indicate the nature of the effect (on
statistical conclusion validity) of each factor that you mention
D) ModeratorsMediators
D1 Moderation and mediation provide different ways to model third variable effects
(a) Please define both of these terms (b) Sketch a conceptual model to show how
each relates to main effects (c) Using variables of your choice please write
hypotheses to reflect both (d) Explain how each is tested analytically
D2 Discuss moderators and mediators Provide an example of how (1) a moderating
variable influences the relationship between the independent and dependent
variable and how (2) a mediating variable influences the relationship between
the independent and dependent variable Describe how you would test for both
moderation and mediation using regression
D3 Many theories in organizational research predict that the effects of one variable
on another are moderated by a third variable Such moderator effects are
typically tested by entering the product of two variables as a predictor after
controlling for the two variables that constitute the product Several researchers
have pointed out that this product is often highly correlated with the squares of
the two constituent variables and have suggested that moderating effects may be
tested after controlling not only for the two constituent variables but also their
squares (eg Cortina 1993 Ganzach 1998 Lubinski amp Humphreys 1990
MacCallum amp Mar 1995) Discuss the strengths and weaknesses of this
approach as compared to methods that use only the product term and its
constituent variables Conclude with recommendations as to when and under
what conditions organizational researchers should test moderator effects with the
squares of the constituent variables in the equation

D4 Assume you are interested in studying relationships amongst three variables X
Y and Z Your first hypothesis posits Z as a mediator of the relationship between
X and Y Your second hypothesis posits Z as a moderator of the relationship
between X and Y Draw the figures depicting each of these hypothesized
relationships and describe (make sure to write regression equations) how you
would test each of these hypotheses
D5 The amount of time and effort that the average person pours into his or her job
has risen steadily over the last two decades such that the average person now is
working one more week per year than the average person in the mid 1970s This
steady increase has fueled research interest in the construct of Job Burnout (JB)
which is an emotional and physical exhaustion associated with ones work
Organizational Stress (OS) the perception of greater demands than available
resources in ones work environment is thought to be one of the chief
antecedents of JB However time spent under OS is thought to make its affects
on JB accumulate or worsen Work Role Withdrawal (WRW) the avoidance of
responsibilities or the deliberate reduction of inputs to ones job is believed to be
the chief consequence of JB
a Formally state these ideas as verbal hypotheses as equations and as a complex
directed graph (circle amp arrow diagram)
b Conceptually what is a mediator Define the term and identify the mediator in
your hypotheses in (a) What elements or steps in a study design (not statistics)

subdomains of management Further demonstrate your understanding of
moderator variables by picking which variable in (a) is the moderator Show the
moderating relationship in an X-Y (or multi-layered) chart Again what elements
or steps in a study design (not statistics) would be helpful for detecting the
moderating effect implied above

F) Applied Data Analysis
16) Q Your departmental chair is considering a new textbook and has asked for your
recommendations You conduct a well-designed controlled study (details are unimportant) and discover students who use the new book perform 10 better on a standardized subject
matter exam than those using the old book (p = 027) Both books are readily availabe their prices are almost identical and both are equally acceptable to the instructors What is your recommendation to the chair
F1 Attached is the beginning of an article Your task is to write the results section by
1 making up and reporting plausible descriptive statistics that will help the
reader understand the results of the statistical tests you report and the nature of your
sample (Hint this can be presented in the form of a table)
2 describing and defending your choice of appropriate statistical tests of the
hypotheses and the steps that you would go through in carrying out these tests
3 making up and reporting results of these tests that are consistent with your
descriptive statistics and with any information in the rest of the article about the
results found (Hint this can be presented in the form of a table)
4 describing how well these results provide support for the hypotheses You
may want to note any relevant threats to validity here
Be sure to state any assumptions you make
F2 Assume that the Personnel Manager of a local firm Ms B dFlandres hired you to
analyze some data that her assistants had collected over the past several years The
data consist of (a) job performance ratings that were made in June of 1990 and (b)
scores on 25 predictor variables (eg measures of education job experience job
tenure job aptitude personality) that were measured when the individuals were hired
(between April 1987 and May 1988) She had data from only the 110 subjects (60
males and 50 females) who were hired during the period and were still employed by
the firm One objective of your analysis (analyses) is to determine how well the
performance criterion can be predicted by the predictors What strategy would you
use in analyzing the data Describeexplain (b) Is sample size an issue for your
analyses Explain If it is what will you do to deal with problems stemming from
sample size Assume that no additional data can be collected at this time (c) Some
preliminary analyses that you do reveal that five of the predictor variables correlate
(zero-order basis) about 75 with one another Will this influence the analyses that
you use Will it influence the validity of conclusions derived from your proposed
analyses (d) Ms dFlandres is interested in knowing if the predictor variables are
equally effective in predicting the job success of males and females What analysis
or analyses would you do to deal with this issue
F3 Assume that you have been provided with data on 12 conceptually distinct variables
that are moderately correlated with one another at the empirical level The data are
from students in four different college majors ie astronomy (A) biology (B)
criminology (C) and demography (D) The 12 measured variables fall into the
general categories of mental health (tension emotional withdrawal hallucinations
guilt feelings blunted affect and suspiciousness) and job satisfaction (work itself
supervision co-workers pay promotion prospects and working conditions) Your
task is to determine if the individuals in the four college majors differ from one
another on the 12 measured variables
(a) What statistical technique(s) would you use to test for group differences
Explain Be specific about the procedures(s) that you would use
(b) What statistical estimate would you use to estimate the extent to which the
groups differ from one another Be specific
F4 The following statistical table published in a recent issue of Work amp Occupations
was taken from an article discussing variables influencing resistance and citizenship
behaviors in the workplace Resistance behaviors include playing dumb withholding
effort work avoidance subverting particular managers and sabotage Citizenship
behaviors include cooperation engaging in peer training use of insider knowledge to
facilitate production commitment to organizational goals giving extra effort freely
Both measures are global constructs aggregated to the interval level and
standardized
The table reports the results of a series of ordinary least squares regression equations
with standardized coefficients Explain the meaning of the statistics presented What
do these statistics tell us generally about the relationship between resistance
behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows
Anomie Index -standardized interval level measure tapping multiple dimensions
The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)
F5 Researchers collected data from a sample of 350 companies on the following
variables
size (measured as number of employees)
Business Strategy (a nominal variable with 2 response options low-cost provider or
differentiator)
HR Strategy (a nominal variable with 2 response categories High commitment or
low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

as you see it within the time span of your career as an academic To do this use
examples of already written (or yet to be written) articles as models
J5 A frequent criticism of non-quantitative research summaries (literature reviews) is

affected the statistical outcomes of the studies included in the literature review Meta-
analysis however allows one to statistically examine such effects Assume you are
conducting a meta-analysis of the relationship between leader behaviors and group
productivity Briefly describe the steps you would take in conducting a meta-

advantages and disadvantages of each
O4 Describe the differences between exploratory factor analysis (EFA) and
confirmatory factor analysis (CFA) When would you use one verses another
Are there ways to use EFA in a confirmatory way Can you use CFA in an
exploratory way Also describe the difference in principal components analysis
(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression
O6 The basic factor analysis model can be represented by the matrix algebraic
equation A B = C

information in each matrix and its purpose
(2) For what purpose do researchers use factor analysis Explain In the process
provide a very brief description of a study for which factor analysis would be a
useful data analytic technique
O7 Factor analysis is an important statistical technique in organizational research

b the type of data necessary for using the technique appropriately
c the type of quantitative output that results from applying the technique
d how a researcher would use the output in his or her research

f the important issues and problems in using the technique
P) Structural Equation Models
P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

parameter estimate bias in structural equation modeling Structural Equation

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)
Please comment on these restrictions versus access argument Which side do you
take
What are the strengths of SEM Give some examples
What are the weaknesses of SEM Give some examples

commissions and boards ranging in size from approximately 50 to over 5000
employees Assume that you wanted to draw a representative sample of 1000
employees Describe two ways that you could draw such a sample and briefly
describe the advantages and disadvantages of each of these sampling approaches
IC
M3 The director of a national non-profit agency with approximately 10000
employees located primarily in regional offices in each of the 50 states the
United States has approached you and asked you to develop a study
(organizational survey) of organizational culture within the agency The agency
is about to embark on a variety of change initiatives including developing team
structures and the study is meant to examine various elements of organizational
culture that are potential barriers to change The director has indicated that he
would like to have the data analyzed at both the individual and office level of
analysis Because of funding limitations the agency will only be able to send the
survey to 1000 employees The director has indicated that there are three ways
of sorting employees all employees listed alphabetically all employees listed
alphabetically by state and all employees listed alphabetically by region (there
are between five and ten regions per state) Given these three ways of sorting
employees describe at least three different sampling approaches and the
advantages and disadvantages of each
M4 In your role as Teacher of Organizational Studies you are asked to prepare a
tutorial for beginning doctoral students on sampling design Assume that this
tutorial is part of a basic class in research design and that students in this class
have had a basic statistics course up to and including multiple regression Your
tutorial should focus on briefly defining and explaining the differences between
probability and non-probability samples You should make sure to present and
describe several types of probability samples (eg random systematic
stratified etc) and non-probability samples (eg convenience snow-ball quota
etc) and discuss general principles for when to use a probability vs a non-
probability sampling design For each sampling design you should also provide
at least one clear example of a situation where this type of sampling design is
appropriate
N) Cross-Cultural Research
N1 Discuss the problems in conducting cross-culturalnational comparison in terms
of (1) conceptualization and (2) research design and data collection
Define the three levels of measurement invariance How would the problems that
you have identified in part (a) affect measurement invariance How would you
examine measurement invariance by confirmatory factor analysis
TH
N2 Explain why using national boundaries as independent variable in cross-cultural
studies may not be appropriate in terms of theory and research methods What
alternative ways would you recommend
IC
O) General
O1 In your readings research has been described as choices among conflicting goals
(desiderata) For instance when choosing among research strategies a researcher
must choose among the desiderata of precision realism and generalizability The
trade-offs among desiderata occur for all aspects of research that is for the selection
of theories the treatment of independent variables research strategies the selection
of the problem to study rules of evidence for determining the meaningfulness of a
research finding and even the frameworks that describe the research process
Discuss what you see as the major trade-offs for each of the following aspects of
research That is discuss what you see as the major strengths and weaknesses
(advantages and disadvantages) of each aspect
a The trade-offs between internal and external validity
b The manipulation of the independent variable vs the observation of the
independent variable
c Basic vs applied research
3 DESIGNING A RESEARCH STUDY
A) General (Research Design)
3) Why is control so important in research design What are the different ways it can be
achieved (give a brief description of each control method) What are advantages and
disadvantages of each
A1 It has become almost a truism to note that the choice of methods influences theory
and questions data and conclusions (the causal direction might also be reversed)
Briefly discuss how the methods used have influenced research in any two of the
following areas leadership power and politics organization culture organization
justice Compare and contrast as possible Suggest some potentially fruitful
methodological directions for future work in these same topical areas and dont be
shy about reflecting on broader issues of how the field of organizational behavior
constructs its realities Lastly tie your discussion and reflections back to your own
future as a researcher what lessons or guidance do you derive from your
understanding of these issues
A2 Characterize as fully as possible what you see to be the methodological approach or
approaches in strategic management research Is there a dominant method or a wide
variety Discuss the reasons for the situation What are the advantages benefits etc
of the approach(es) in use What assumptions (ontological epistemological
ideological) do they embody Are current efforts ideal or at least adequate Are
there other approaches that could be useful If so how might researchers be
encouraged to use these as well If you see no advantage to more variety in
methodological approach support that point of view
A3 Describe a research question or area of interest to you and why you think it is not
only of interest but significance Using your understanding of research methodology
describe two ways of pursing the question that are as divergent on as many
dimensions as you can imagine Describe the advantages and disadvantages of each
approach How strong a link or fit is there between a research question and a
method
A4 In his 1957 article entitled The two disciplines of scientific psychology Cronbach
discussed the assumptions goals and methods used in experimental methods and
correlational methods in psychology
a According to Cronbach what is the main difference between the two disciplines
b Discuss the strength and weaknesses of each discipline
c What if anything could be done to improve the situation
B) Designing a Research Study
B1 Cook and Campbell describe the experiment as the research design with the
greatest methodological rigor However given the constraints present in most
organizations I-O Psychologists cannot often conduct experiments in applied
settings and must settle for techniques with less control than experiments
Describe a study to investigate the relationship between participation in a
supervisor training program and work performance which could realistically be
conducted in an organization If an experiment is not possible describe how you
would go about maximizing your ability to draw valid conclusions from your
design
B2 The XYZ Co has recently developed a sexual harassment web-based training
program The developers claim the program will cut training time and costs and
will be as effective or more effective than classroom-based sessions They
believe that this will be due to the increased availability of the program and the
ability for participants to review program material on demand Before the XYZ
Co developers launch this product they want you to determine if their claims
have merit Explain how you would design a study for this purpose
B3 Research suggests that demographic diversity improves group creativity but
reduces group efficiency Some argue that demographic diversity is just a proxy
for value and experience diversity and that demographic diversity on its own is
meaningless Design a test to settle this argument
TH
B4 E-mail has become a common form of communication in organizations and is
used for both formal and informal communication Because it has become so
IC
popular some people complain that the frequent use of e-mail leads to
miscommunication because they receive communications in e-mail that should
be accomplished through face-to-face or telephone conversations where there is
an opportunity for interaction You are interested in looking at this
phenomenon You are most interested in describing how e-mail is used for both
formal and informal communication and in examining the effect of the e-mail
use on organizational communication effectiveness Design empirical research
to address those issues
Describe your study in detail thoroughly explaining the research design
sampling plan data collection procedures ethical issues and proposed data
analysis for your research design Be sure to discuss the internal and external
validity of your research Which validity threats are ruled out and which
remain
REMEMBER Be thorough Your research design should demonstrate that you
are a competent researcher who is knowledgeable about the proposed research
methodology or methodologies Therefore be sure that you carefully describe
and give technical explanations for each component of your research
B5 Choose a specific situation involving employee selection eg artists for an
advertising agency (a) What strategy would you use in selecting the selection
measures (b) How would you combine the measures eg which measures
would you combine in a compensatory manner and which is a noncompensatory
manner (c) How would you assume test fairness defining various measures of
the term (d) How would you make final selections (e) How would you
validate your procedure (f) What considerations would enter in if your
company were too small to provide validation data (g) What difference would
it make if you were developing a procedure for deciding whether trainees
should be promoted as opposed to making new hires Please note--emphasize
but do not limit yourself to statistical issues
B6 There is evidence in the marketing literature of a non-monotonic relationship
between the expectations that customers have for retail service and their
eventual level of satisfaction with that service That is as a customers
expectations for service increase so does their eventual service satisfaction --
up to a point After that point the greater the expectations the lower the
eventual satisfaction Develop a hypothesis that includes a moderator variable
that might account for this evidence Give some reasonable rationale for it State
your hypothesis verbally as an equation as a directed graph (circle amp arrow
diagram) and as an X-Y function chart Discuss how it would or would not be
possible or useful to test your hypothesis via a laboratory experiment In your
discussion cover how and why a researcher could (not) manipulate the
independent constructs involved (mode X) whether or not random assignment
to conditions (mode R) is possible (including how may conditions would be
necessary) which alternative constructs could or could not be controlled (mode
K) and which constructs should be measured (mode Y)
B7 Assume you are the chairperson of a committee that must evaluate
undergraduate programs at your university Your task as chairperson is to
devise an approach (a design a research strategy a set of measures) that will
allow you to evaluate undergraduate programs Make sure that your approach
can be used in the future and at other comparable universities When developing
your plan be sure to address at least the following issues
a the type of design you would select Compare and contrast the selected design
with another possible design
b the type of research strategy you would select Compare and contrast with
another possible strategies
c discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
B8 Assume you are an organizational research design expert assigned to the
Strategic Planning Department of a large multi-national manufacturing firm
The Department has developed a new PC-based software package called
STRATPACK The software (and a one-week training course to learn how to
use it) is intended to improve the long-range planning ability of middle and
upper-level managers
Your job as research design expert is to devise research (a design a research
strategy a set of measures) that will allow you to evaluate the effectiveness of
the STRATPACK program Describe a research design for evaluating the
program Make sure that your research approach can be used in the future and at
all sites in the company When developing your plan be sure to address at least
the following issues
a discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
b the type of design you would select (eg a design where you manipulate the
independent variable versus observe the independent variable) Compare and
contrast the selected design with another possible design
c how your design deals with the major forms of validity Be sure to examine at
least internal external and construct validity
B9 Assume you are a consultant hired to evaluate the effectiveness of an industrial
safety program undertaken by a large manufacturing organization The safety
program is a behavioral one that provides rewards such as monetary bonuses or
extra paid vacation days for safety behaviors in terms of accident-free days
weeks etc Your task is to devise an approach (a research strategy a design a
set of measures and a general analysis strategy) that will allow you to evaluate
the safety program Because of the potential for the influence of many
extraneous variables on any safety program it is difficult to design research a
single cross-sectional study than can evaluate the impact of a single safety
program How would you design a study to evaluate the impact of the safety
program When developing your plan be sure to address at least the following
issues
a the type of research strategy you would select Compare and contrast with
another possible strategies
b the type of design you would select Compare and contrast the selected design
with another possible design
c discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
B10 One of the most important areas of research is forecasting of human resources
needs based on strategic positions of organizations For example NY State must
carefully forecast its human resources needs as it proceeds with significant lay-
offs of state employees Future human resources needs are generally evaluated
by either statistical ie regression or simulation or clinical judgment i e
supervisors judgments methods
a Design a single study that addresses the empirical question of whether
statistical or judgmental methods are better for forecasting human resources
needs You may discuss a program of research but please be quite specific in
your description of the first study
b What are the critical methodological issues in doing this kind of research
c What are the critical applied (or practical) issues in doing this research
d Are the issues in b and c related
B11 In the past decade computinginformation technology has changed many
aspects of organizational life For example the technology can make increased
decentralization possible by improving communication between central offices
and field offices Computer networks and word processors can enhance group
empowerment by making it possible for team members to create and edit
written group products quickly even if the individuals are at different locations
Some have argued that computinginformation technology will foster the
paperless productive office nevertheless others argue that the technology only
increases paper and reduces office productivity You are applying to the
National Science Foundation for a grant to conduct research that examines the
impact of computing information technology on organizational decision
processes The NSF application procedure imposes five basic requirements that
your research design must fulfill in order to receive funding Note A very
significant factor affecting NSF grant decisions is a clear demonstration that the
researcher is knowledgeable about the research methodology used Write your
response to each of the following five grant requirements Be sure not only to
respond to the requirement but also to demonstrate your research
competence
1You must design a study that uses two different methods
(interviewobservation survey experiment or quasi-experiment) Describe your
two methods in detail and provide a rationale for the key elements (eg
sampling data collection proposed analysis) of your methods Be sure to
discuss and evaluate the internal and external validity of both methods
2 As part of your research design you must select a conceptual (latent) variable
central to your proposal (use centralization of decision making as your
variable) and describe how you will develop your own measure (You may not
simply use off the shelf instruments)
3 You must describe how you will test for the reliability of the measure
(centralization of decision making) you developed in step 2 The NSF insists
that you describe how you will evaluate both the temporal stability and the
internal consistency of your measure Be sure to discuss what temporal stability
and internal reliability mean and how they are related
4You must describe how you will assess the validity of the measure
(centralization of decision making) you developed in step 2
5 NSF requires a brief statement and defense of the philosophy of science
underlying your research Discuss your position and show how your research
design is consistent with your philosophy
B12 Many organizations in the United States economy have installed some form of
Empowered Teams as an alternative or supplement to traditional bureaucratic
structure Preliminary evidence of the effectiveness of empowered teams
however is mixed--some organizations have claimed success and others have
reported failures The evidence however is predominantly anecdotal--written
for trade magazines by the organizations themselves There are few rigorous
empirical studies assessing the effectiveness of empowered or self-managed
teams You are applying to the United States Department of Labor (USDOL) for
a grant to conduct research that examines the effectiveness of empowered
teams The application procedure of the USDOL imposes three requirements
that your research design must fulfill in order to receive funding Write your
response to each of the three grant requirements The importance of each section
is implied by the evaluation points allocated by the USDOL to each of the three
requirements given in parentheses
1 (50 points) Your study design for assessing Empowered Team effectiveness
must use two different methods (interview observation archival analysis
survey simulation experiment or quasi-experiment) Describe in detail and
thoroughly explain the sampling plan instrumentation data collection
procedures and proposed data analyses for both methods Be sure to discuss the
internal and external validity of both methods and how the two methods
complement one another
2 (30 points) As part of your research design you must select one conceptual
(latent) variable central to your proposal and describe how you will develop
your own operationalization of the measure (You may not simply use off the
shelf instruments) Use the concept of group morale to demonstrate your
operationalization methodology Be sure to explain very explicitly to the
USDOL how you will assess the validity and reliability of the group morale
measure you are developing
3 (20 points) The USDOL traditionally has funded research conducted only
within the general paradigm of logical positivism but now is more open to other
research paradigms as well Your grant proposal must provide a statement and
defense of the explicit philosophy of science underlying your research Describe
your philosophy of science and show how your research design is consistent
with your philosophy
REMEMBER Be thorough You not only must design effective research but
you also must demonstrate to the USDOL that you are a competent researcher
It is absolutely vital to the USDOL that the principal researcher is
knowledgeable about the proposed research methodologies Therefore be sure
that you always carefully describe and give technical explanations for each
component of your research design and explain all technical terms (eg
Cronbach alpha KR-20 Likert scale)
B13 Assume that you are working as part of a research team that is responding to a
RFP (Request for Proposals) from a funding agency for research on work
socialization and newcomer adjustment The RFP calls for rigorous field
research that tests the effectiveness of theory-based interventions aimed at
facilitating the adjustment of new organizational members to complex andor
stressful work conditions The major goal of your teams research is to test the
effectiveness of a self-regulation intervention which trains newcomers to
identify and use relevant social information and cues to regulate work behavior
Your group hypothesizes that self-regulation training will be more effective
than other common treatments or interventions (eg realistic job previews
institutionalized socialization tactics)
You have been included in the team because of your methodological expertise
Your role is to design a rigorous field experiment or quasi-experiment to test he
effectiveness of the self-regulation training program REMEMBER THE
MAJOR CRITERION FOR FUNDING IS THE RIGOR OF THE RESEARCH
DESIGN Design a field study to include in the grant proposal Your proposal
should contain the following two sections
1 Study Design Construct and describe in detail an experimental or quasi-
experimental design to test the effectiveness of your intervention Describe in
detail the experimental groups (including how they will be constructed) the
research setting the sampling plan for study participants the treatment
manipulation and the data collection procedures Also indicate any control or
nuisance variables that may be measured
After describing the procedures write a justification of the design What threats
to validity does it rule out or limit and what threats to validity remain
II Measurement Describe the steps you would take to achieve valid and
reliable measure of the latent (conceptual) variable worker adjustment Your
team feels that as part of the proposal you must develop an original
operationalization of adjustment (thus you cannot simply use existing off the
shelf measures) Indicate in adequate detail how you would operationalize the
measure and indicate how you would demonstrate reliability and validity
B14 In describing their notion of the collective mind Karl E Weick and Karlene H
Roberts note Our focus is at once on individuals and the collective since only
individuals can contribute to a collective mind but a collective mind is distinct
from an individual because it inheres in the pattern of interrelated activities
among many people (p 360) Collective mind is not indexed by within-group
similarity of attitudes ideas or activities A collective mind is one in which
many people or many groups integrate their different attitudes ideas and
activities heedfully As Weick and Roberts note People act heedfully when
they act more or less carefully critically consistently purposefully attentively
studiously vigilantly conscientiously pertinaciously (p 361)
The idea of the collective mind as heedful interrelating is developed in the
following excerpt When people make efforts to interrelate these efforts can
range from heedful to heedless The more heed reflected in a pattern of
interrelations the more developed the collective mind and the greater the
capability to comprehend unexpected events that evolve rapidly in unexpected
ways When we say that a collective mind comprehends unexpected events we
mean that heedful interrelating connects sufficient know-how to meet situational
demands For organizations concerned with reliability those developments
often consist of unexpected non-sequential interaction (p366)
An example of heedful interrelating occurs as a pilot lands herhis aircraft on the
deck of an aircraft carrier The pilot does not actually land She is recovered
A recovery is an interrelated set of activities among air traffic controllers
landing signal officers the control tower navigators deck hands the helmsman
driving the ship etc These activities can be interrelated more or less heedfully
depending on the care with which the different units contribute represent the
situation and subordinate their activities to the single purpose of successful
recovery (p 363)
You are to design a two-part study
Part I You are to design a measurement study which assesses heedful
interrelating (ie collective mind) with a quantitative measure in a replication
of an aircraft carrier flight deck or other situation of your choosing Describe
your research strategies including operationalization of the variable selection of
the sample subjects data collection data analysis and so on for the purpose of
developing a measure of heedful interrelating
Part II Using the measurement tool developed in Part I and any other tools as
needed describe how you would design a study which would compare heedful
interrelating across organizations Choose at least one macro-organizational
variable (eg technology environment) as your basis of comparison Here you
must describe how you would make your selection of organizations to be
compared your data collection procedure data analysis and so on
B15 Many organizations in the United States have installed cross-functional teams to
counteract the silo mentality of traditional bureaucratic structure Preliminary
evidence of the effectiveness of cross-functional teams however is mixed --
some organizations have claimed success and others have reported failures The
evidence moreover is predominantly anecdotal--written for trade magazines by
the organizations themselves Since there have been few rigorous empirical
field studies assessing the effectiveness of cross functional teams the National
Science Foundation has decided to fund research on the topic
Assume that you are submitting a research proposal to NSF for a grant to
research the effectiveness of cross-functional teams Describe in detail and
thoroughly explain the research design sampling plan data collection
procedures ethical issues and proposed data analysis for your research design
Be sure to discuss the internal and external validity of your research Which
validity threats are ruled out and which remain NSF also requires that you
provide a statement and defense of the explicit philosophy of science underlying
your research Describe your philosophy of science and discuss how your
research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but
you must also demonstrate to NSF that you are a competent researcher It is
absolutely vital to NSF that the principal researcher (you) is knowledgeable
about the proposed research methodologies Therefore be sure that you always
carefully describe and give technical explanations for each component of your
research design and explain all technical terms (eg Cronbach alpha KR-20
Likert scale)
B16 Assume that you are submitting a research proposal to the Department of
Commerce (DoC) for a grant to research the effectiveness of virtual work teams
A virtual work team is a leaderless collection of individuals who are
geographically separate from one another and share their expertise using
internet media such as a listserver or Lotus notes The DoC requires that the
researcher use both qualitative and quantitative methods to gather data Describe
in detail and thoroughly explain the research design sampling plan data
collection procedures ethical issues and proposed data analysis for your
research design Be sure to discuss the internal and external validity of your
research Which validity threats are ruled out and which remain The DoC also
requires that you provide a statement and defense of the explicit philosophy of
science underlying your research Describe your philosophy of science and
discuss how your research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but
you must also demonstrate to DoC that you are a competent researcher It is
absolutely vital to DoC that the principal investigator (you) is knowledgeable
about the proposed research methodologies Therefore be sure that you always
carefully describe and give technical explanations for each component of your
research

that improves upon the key validity (or validities)
5 MEASUREMENT
A) Measurement Terms
A1 There are four levels of measurement rigor in management research Discuss each
one What properties do measurements at each level have (ie how much
information do the numbers from each level of measurement convey) How can the
numbers be changed (transformed) and still retain the properties of their
measurement level Pick one construct from a favorite research domain and give an
example of an operationalization of that construct at each of the four levels of
measurement rigor (provide arguments about why you think those examples reflect
each level) Lastly treat each examplelevel as a dependent variable in some
statistical analysis Given an example of a statistical technique appropriate for
analyzing data at that level of measurement rigor
A2 Define (and discuss important features or issues concerning) the following
constructs measurement (Define any six terms)
1 Construct validity 6 Item analysis
2 Likert scaling 7 Semantic differential
3 Cronbachs alpha 8 True score
4 Unobtrusive (trace) measurement 9 Generalizability theory
5 Interval scale 10 Criterion-related validity
11 Sociometric choice measures
B) Operationalization
B1 a) You are conducting a study which requires you to measure Hong Kong real
estate agents self-assessment of performance Since there is no existing
measurement available you have to develop the instrument by yourself
Describe how you would develop the measurement assuming that you have no
idea of how many dimension the construct has
b) Suppose you have developed an instrument consists of 20 questions
measuring 4 dimensions (5 items per dimension) from (a) You collected data
from another 300 real estate agents to validate your instrument Explain how
TH
you would use structural equations model (SEM) to examine the reliability and
validity of the instrument What are other concerns about reliability and validity
that are not addressed by this approach
B2 The research and business world have been fascinated with the concept of
organizational culture However operationalizing this construct has been a
difficult task Discuss the ways in which the construct has been operationalized
(eg technique static v dynamic sample selection generalizability) Critically
analyze each of these methodologies Then choose a methodology you would
use to examine organizational culture and defend your choice Describe how
you would study culture and what more would be known about culture as a
result of your study
B3 Suppose you are setting out to develop a new measure of a construct You want
this measure to be used in survey research and you want to establish its validity
and reliability Your goal is to have at the end of the process a measure that is
defensible and likely to be widely accepted by other researchers studying that
construct What steps would you take to conduct such a program of research
For each step explain the purpose of that step explain why that step is
important explain what methods and statistical procedures you would employ at
each step and explain what evidence you would hope to gather at each step
B4 Assume you are interested in constructing a new measure of (fill in with a
relevant variable from your field) Detail the major concerns that need to be
addressed and the steps that need to be taken in working toward validating this
new measure
B5 Assume that you recently read an article on workplace violence which you
found very interesting The authors argued that one of the predictors of
workplace violence was a construct called propensity to be violent and used a
one-item measure as follows How likely are you to become violent when
provoked You had serious doubts about the authors measure and decided to
develop your own
(a) How would you go about developing items to measure propensity to be
violent
(b) How would you determine whether the instrument was reliable
How would you determine whether the instrument was valid
B6 A concern in organizations is retirement of baby boomers within the next 5 -
10 years This concern is focused on the loss of older employees with skills
critical to the core business functions of organizations In order to continue to
have employees with those critical skills it seems necessary to retrain some
older workers However past practice in most organizations has been not to
retrain older workers for a variety of reasons mostly financial A researcher
working for the Human Resources Department of a large corporation - 13500
employees in 12 different plant locations - hypothesizes that the major reason
for not retraining older workers is ingrained in the culture of the corporation
IC
The researcher feels that older workers are not as highly valued as younger
workers in terms of their potential usefulness after retraining The researcher
searched the literature but found nothing in the existing literature to measure
the cultural value construct What should the researcher do to establish a reliable
and valid self-administered paper and pencil measure of this construct namely
the value of retraining older workers
a Please describe and explain the steps in temporal order that the researcher
must follow to develop a measure
b How would you evaluate the measure based on the technical requirements of
reliable and valid measurement as well as any practical issues in using the
measure considering the size of the employee population
B7 Assume that you are going to conduct empirical research to assess the role that
the complexity of an organizations manufacturing technology plays in
determining the level of centrality of decision making in the organization
Describe and justify the steps you might follow to develop an operationalization
of the concept of technological complexity What standards would you use to
determine if your operationalization is valid
B8 Organizational researchers have several strategies available to them for
gathering information (eg self-report measures archival measures direct
observation and trace measures) Assume that you are going to conduct
empirical research to assess the role that the structure of the organization plays
in determining the level of organizational effectiveness Briefly review the
strengths and weaknesses of the basic strategies (that is self-report measures
archival measures direct observation and trace measures) for measuring
organizational effectiveness Next describe and justify the steps you would
take to develop an operationalization of the concept of organizational
effectiveness What standards and procedures would you use to determine if
your operationalization is valid
B9 One of the most important topics of recent research has been stress in the work
place One of the most important problems with understanding this literature is
the varying definitions and measurement of this construct Suppose you had
decided to investigate the relationship between stress at the work place and dual
career family happiness
a Since there are multiple ways to measure stress in the work place describe
two ways to do this Hint - avoid using two self-report measures
b Describe how you would decide on the best single measure In doing so
describe the steps you would take in evaluating your measure Be sure to define
your meaning of validity and reliability It is important that your measure have
all the necessary psychometric characteristics so that other scientist can trust the
results of your research
c Be certain that you answer the question Validity for what
d In order to understand the results of your study you need to compare your
measure of stress at work with other measures of this construct How would you
do that
B10 Assume that you have been hired by a national survey research company
Shash Inc to write items that will be used in a national survey of attitudes
toward capital punishment There are a number of criteria that can be used to
guide your item writing What are they Briefly describe five (5) such criteria
B11 Assume that you are going to conduct empirical research to determine the
impact of interpersonal trust on organizational decision making Describe and
justify the steps you might follow to develop an operationalization of the
interpersonal trust concept
B12 Assume that you are going to conduct empirical field research to assess the role
that employee empowerment plays in determining the level of organizational
commitment of employees Describe and justifyexplain the steps you would
follow to develop a valid and reliable operationalization of the concept of
employee empowerment
Explain the procedures and standards you would use to determine if your
operationalization is valid and reliable
How would you assess the construct validity of such a measure
Discuss issues concerning the level of observation of your measure and level of
analysis of the data
B13 Assume you are interested in developing a new scale to measure construct X
Further assume that you have used previous literature and your own conceptual
development to delineate 2 dimensions of X specifically XF1 and XF2
Describe the steps you would go through in developing testing and evaluating
this new scale With regard to testing and evaluating be sure to consider the
role of factor analysis (both exploratory and confirmatory) and item analysis
Also you will want to make sure that your new multidimensional scale shows
evidence of validity (several kinds) and reliability so be sure to examine these
issues and explain how specific information gathered from the above testing
contributes to these concerns
C) Reliability
4) What is reliability and why is it so important What are the different ways reliability can be
assessed and when is each appropriate
15) What does coefficient alpha assess What are the ways coefficient alpha can be increased
C1 Describe and discuss the concept of reliability and all of its various forms
including their assessment When is each form appropriate and what information
is provided by each index
C2 In establishing congruence between multiple measurements we often compute
indices of reliability andor indices of agreement These two types of indices
address very different questions Your task is to 1) Define reliability and
agreement 2) Explain when each is useful using examples in which one but not
the other is appropriate and 3) Briefly describe two reliability indices and two
agreement indices
C3 Explain reliability in terms of the classical test theory What are the
consequences of unreliable measures in hypothesis testing What are the factors
that may affect the reliability of a multi-item scale
IC
C4 Generalizability theory is used within IO psychology more often today
However most researchers continue to use Classical Test Theory
conceptualizations of error to determine reliability What are the implications of
using classical test theory versus generalizability theory to assess reliability
C5 In establishing congruence between measurements we often compute indices of
reliability andor agreement Define reliability and agreement Explain the
differences in reliability and agreement and describe under what conditions
assessing reliability is more appropriate and under what conditions assessing
agreement is more appropriate
C6 Define measurement reliability in terms of a specific measurement theory (eg
true test score theory domain sampling theory generalizability theory IRT)
Discuss the different approaches for estimating reliability and the contexts in
which each might be appropriate Use examples throughout
C7 What are the consequences of unreliability in a measure
C8 What are some of the conditions that might keep the internal consistency (eg
alpha) of a given measure low Is a low alpha always a sign of a problematic
measure
C9 Define reliability Name some methods of calculating reliability How well do
these methods map up with the definition of reliability What is the impact of the
number of test items and sample size on Chronbachs alpha and why would this
effect occur or not occur (Note Do NOT discuss inter-rater reliability)
C10 Schmidt and Hunter (1996) described several types of measures typically used in
organizational research and identified the type(s) of measurement error affecting
each of them in various situations For each measure below indicate the types of
error and sources of error that are most likely to affect it Then indicate what

C11 Suppose you had conducted research on the relationship between organizational
commitment and rigidity of organizational structure in 200 firms Your measure
of rigidity was based on number of organizational authority levels and the degree
to which written organizational rules existed and defined role behaviors for
employees Thus an organization with a large number of organizational levels
and specific written policies defining appropriate role behaviors for employees
would score high on rigidity of organizational structure After analyzing your
data you find that there is a statistically significant negative correlation between
commitment and rigidity which is consistent with your hypothesis However the
reliabilities for your two measures are
(1) commitment = 23 (2) rigidity = 83
How should you interpret your results What could you do to fix this situation
Describe the specific steps (in order) you would follow to develop a more
reliable measure of commitment
C12 (a) Define the concept of reliability (of measures) in a clear concise and
accurate manner (b) Provide a formula that expresses the reliability of a measure
in terms of two components of variance ie total variance and the error
variance
D) Multi-level Assessment
D1 One of the major challenges for group-level research is the issue of aggregation of
individual data to the group level
(a) Under what conditions (eg types of data number of raters) should the various
interrater agreement and reliability methods be used (Rwg Kappa and Weighted
Kappa percent agreement average pairwise correlation ANOVA methods
(interclass correlation coefficient WABA)) What are the advantages and
disadvantages of each of the methods
(b) Explain the controversy between Frank Schmidt Larry James and others
regarding the differences between interrater agreement and interrater reliability
Who is right Do the differences matter in research practice
Defend your answers
(c) Review two articles from the organizational behavior literature that have had to
deal with aggregation issues Critique the methods the authors used to make
aggregation decisions
(d) Provide some advice to researchers regarding what they should do if interrater
agreement and reliability indices indicate that it is not legitimate to aggregate their
data
(e) Provide some ideas for avoiding the need to aggregate in group-level research
through creative research methods and measurement strategies
D2 Cross-levelmulti-level research is becoming more evident in the organizational
research literature This type of research raises many issues and presents many
challenges in terms of designing the research measuring variables and collecting
and analyzing the data Assume that you are interested in aggregating data (eg
from the individual to the group or from the firm to the industry) for one or more
variables What are the major issues you will need to deal with
D3 A researcher wants to measure organizational climate for continuous learning
Organizational climate is operationalized as a shared consensual aspect of the
organization -- the shared perception among employees that the organization values
and supports continuous learning Describe how you would measure organizational
climate in this case Specify (a) the level (ie individual group organization) at
which the construct exists (b) the level at which you would measure the construct
and (c) the procedures that you would use to establish that measurement is aligned
with theory (ie the construct validity of the measure)
E) General (Measurement)
E1 Studies in organizational behavior research often rely on single-item measures of
key constructs The use of single-item measures has long been criticized based
on the premise that single-item measures are unreliable However Wanous
(Wanous amp Hudy 2001 Wanous amp Reichers 1996 Wanous Reichers amp Hudy
1997) has recently argued that single-item measures can exhibit adequate
reliability Wanous based this conclusion on a procedure for estimating the
reliability of single-item measures using the classic formula for correction for
attenuation Subsequent studies have yielded mixed results regarding the
conclusions of Wanous (eg Loo amp Kells 1998 Nagy 2002) and the veracity
of the perspective advocated by Wanous remains in question Summarize and
assess the arguments for and against the use of single-item measures and
evaluate the procedure and evidence offered by Wanous regarding the reliability
of single-item measures Based on your assessment and evaluation develop
recommendations regarding the use of single-item measures in organizational
behavior research

E2 Ipsative measures have become prevalent in organizational behavior research
Ipsative measures ask respondents to answer questions relative to one another
such that the scores for all questions sum to the same constant for all respondents
Examples of ipsative measures include rankings Q-sorts and the allocation of a
fixed number of points (eg 100) across a set of response options Ipsative
measures may be contrasted with absolute measures which ask respondents to
answer questions independently from one another Absolute measures are
exemplified by rating scales using an interval or ratio numeric response format
The relative merits of ipsative and absolute measures have been debated for
decades (eg Cornwell amp Dunlap 1994 Hicks 1970 Johnson Wood amp
Blinkhorn 1988 Saville amp Wilson 1991 1992) yet the fundamental issues
underlying this debate have not been adequately addressed in organizational
behavior research For example measures of organizational culture and values
are often ipsative and some researchers advocate these measures over absolute
measures (eg Meglino amp Ravlin 1987 OReilly Chatman amp Caldwell 1991
Ravlin amp Meglino 1987 see also Rokeach amp Ball-Rokeach 1989) Review the
relative merits of absolute and ipsative measures Based on your review which
form of measurement is most appropriate and why Do your conclusions depend
on the construct being measured If so what types of constructs are best suited to
ipsative measures and what types are best suited to absolute measures Next
apply your conclusions to the measurement of culture and values in
organizations What specific arguments have been advanced in favor of ipsative
measures of culture and values How sound are these arguments Should ipsative
measures be used in the study of organizational culture and values If not how
can absolute measures of culture and values be developed that address the
concerns voiced by advocates of ipsative measures Provide a specific example
of the type of measure you would propose

E3 In organizational research measures often consist of items that represent different
facets of a concept Although such measures are prevalent and in some cases are
advocated (eg Law et al 1998 1999) they can present a variety of conceptual
and methodological problems Describe the specific problems associated with
measures that use items representing different facets of a concept Compare these
problems with the purported advantages of such measures Conclude by

E5 Suppose Roberta Von Eisenbrick is a researcher interested in the consequences of
AFFECTIVE CONFLICT (AC) in decision-making teams She gets access to a
variety of outcomes assessment committees at each of 87 different schools in
the Dallas Independent School District and gains permission to tape-record two
of their meetings (one in February and one in March) Such committees have
been formed to develop quantitative ways to track pursuit of school goals and
provide accountability to local and state governments These are often divisive
teams with heated meetings because what gets assessed is what usually gets
rewarded After both of these meetings the committee members each
fill out a short questionnaire that contains 20 Likert-type items measuring how
much AC occurred (eg People in our group often get angry with each other)
The individual scores are summed across items then averaged across team
members to come up with a group-level AC score for each of the 87 2
meetings The same procedures are followed for a 5-item measure of Group
Cohesiveness (GC) which is predicted to be reduced by higher levels of AC
Roberta also listens to every tape and from her expert judgment she rates each
groups meetings on the same 20 items Those 20 ratings are summed for each of
the 87 2 meetings Now Roberta is interested in evaluating her measure She
wants it to have excellent psychometric properties including reliability and
construct validity

problems engendered by significance testing and why have these remedies not
been widely adopted

things that researchers have inappropriately sanctified the p lt 05 level of
significance Describe and critique the arguments for and against the use of
statistical significance testing in empirical research What information other than

D) ModeratorsMediators
D1 Moderation and mediation provide different ways to model third variable effects
(a) Please define both of these terms (b) Sketch a conceptual model to show how
each relates to main effects (c) Using variables of your choice please write
hypotheses to reflect both (d) Explain how each is tested analytically
D2 Discuss moderators and mediators Provide an example of how (1) a moderating
variable influences the relationship between the independent and dependent
variable and how (2) a mediating variable influences the relationship between
the independent and dependent variable Describe how you would test for both
moderation and mediation using regression
D3 Many theories in organizational research predict that the effects of one variable
on another are moderated by a third variable Such moderator effects are
typically tested by entering the product of two variables as a predictor after
controlling for the two variables that constitute the product Several researchers
have pointed out that this product is often highly correlated with the squares of
the two constituent variables and have suggested that moderating effects may be
tested after controlling not only for the two constituent variables but also their
squares (eg Cortina 1993 Ganzach 1998 Lubinski amp Humphreys 1990
MacCallum amp Mar 1995) Discuss the strengths and weaknesses of this
approach as compared to methods that use only the product term and its
constituent variables Conclude with recommendations as to when and under
what conditions organizational researchers should test moderator effects with the
squares of the constituent variables in the equation

D4 Assume you are interested in studying relationships amongst three variables X
Y and Z Your first hypothesis posits Z as a mediator of the relationship between
X and Y Your second hypothesis posits Z as a moderator of the relationship
between X and Y Draw the figures depicting each of these hypothesized
relationships and describe (make sure to write regression equations) how you
would test each of these hypotheses
D5 The amount of time and effort that the average person pours into his or her job
has risen steadily over the last two decades such that the average person now is
working one more week per year than the average person in the mid 1970s This
steady increase has fueled research interest in the construct of Job Burnout (JB)
which is an emotional and physical exhaustion associated with ones work
Organizational Stress (OS) the perception of greater demands than available
resources in ones work environment is thought to be one of the chief
antecedents of JB However time spent under OS is thought to make its affects
on JB accumulate or worsen Work Role Withdrawal (WRW) the avoidance of
responsibilities or the deliberate reduction of inputs to ones job is believed to be
the chief consequence of JB
a Formally state these ideas as verbal hypotheses as equations and as a complex
directed graph (circle amp arrow diagram)
b Conceptually what is a mediator Define the term and identify the mediator in
your hypotheses in (a) What elements or steps in a study design (not statistics)
that would be helpful for detecting the mediating relationship that was proposed
c What is a moderator What are some of the other names for it within various
subdomains of management Further demonstrate your understanding of
moderator variables by picking which variable in (a) is the moderator Show the
moderating relationship in an X-Y (or multi-layered) chart Again what elements
or steps in a study design (not statistics) would be helpful for detecting the
moderating effect implied above
E) Multiple Comparisons
E1 In your role as professional colleague you are called upon to advise another doctoral
student about the appropriate use of multiple comparisons and post hoc tests in
analysis of variance Your student colleague already has been introduced to ANOVA
and multiple regression Specifically you are to write out a description of how to test
for differences among the different levels or cells of a categorical variable In your
description you should discuss among other things
a the statistical and philosophical issues raised by post hoc analysis and data
snooping
b the different multiple comparison methods commonly used by researchers to test
for differences among cell means and
c the advantages and disadvantages of each method
Note Your written description will be evaluated based on your demonstrated
competence with the statistical method not on the pedagogy of your explanation

recommendations You conduct a well-designed controlled study (details are unimportant) and discover students who use the new book perform 10 better on a standardized subject
matter exam than those using the old book (p = 027) Both books are readily availabe their prices are almost identical and both are equally acceptable to the instructors What is your recommendation to the chair
F1 Attached is the beginning of an article Your task is to write the results section by
1 making up and reporting plausible descriptive statistics that will help the
reader understand the results of the statistical tests you report and the nature of your
sample (Hint this can be presented in the form of a table)
2 describing and defending your choice of appropriate statistical tests of the
hypotheses and the steps that you would go through in carrying out these tests
3 making up and reporting results of these tests that are consistent with your
descriptive statistics and with any information in the rest of the article about the
results found (Hint this can be presented in the form of a table)
4 describing how well these results provide support for the hypotheses You
may want to note any relevant threats to validity here
Be sure to state any assumptions you make
F2 Assume that the Personnel Manager of a local firm Ms B dFlandres hired you to
analyze some data that her assistants had collected over the past several years The
data consist of (a) job performance ratings that were made in June of 1990 and (b)
scores on 25 predictor variables (eg measures of education job experience job
tenure job aptitude personality) that were measured when the individuals were hired
(between April 1987 and May 1988) She had data from only the 110 subjects (60
males and 50 females) who were hired during the period and were still employed by
the firm One objective of your analysis (analyses) is to determine how well the
performance criterion can be predicted by the predictors What strategy would you
use in analyzing the data Describeexplain (b) Is sample size an issue for your
analyses Explain If it is what will you do to deal with problems stemming from
sample size Assume that no additional data can be collected at this time (c) Some
preliminary analyses that you do reveal that five of the predictor variables correlate
(zero-order basis) about 75 with one another Will this influence the analyses that
you use Will it influence the validity of conclusions derived from your proposed
analyses (d) Ms dFlandres is interested in knowing if the predictor variables are
equally effective in predicting the job success of males and females What analysis
or analyses would you do to deal with this issue
F3 Assume that you have been provided with data on 12 conceptually distinct variables
that are moderately correlated with one another at the empirical level The data are
from students in four different college majors ie astronomy (A) biology (B)
criminology (C) and demography (D) The 12 measured variables fall into the
general categories of mental health (tension emotional withdrawal hallucinations
guilt feelings blunted affect and suspiciousness) and job satisfaction (work itself
supervision co-workers pay promotion prospects and working conditions) Your
task is to determine if the individuals in the four college majors differ from one
another on the 12 measured variables
(a) What statistical technique(s) would you use to test for group differences
Explain Be specific about the procedures(s) that you would use
(b) What statistical estimate would you use to estimate the extent to which the
groups differ from one another Be specific
F4 The following statistical table published in a recent issue of Work amp Occupations
was taken from an article discussing variables influencing resistance and citizenship
behaviors in the workplace Resistance behaviors include playing dumb withholding
effort work avoidance subverting particular managers and sabotage Citizenship
behaviors include cooperation engaging in peer training use of insider knowledge to
facilitate production commitment to organizational goals giving extra effort freely
Both measures are global constructs aggregated to the interval level and
standardized
The table reports the results of a series of ordinary least squares regression equations
with standardized coefficients Explain the meaning of the statistics presented What
do these statistics tell us generally about the relationship between resistance
behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows
Anomie Index -standardized interval level measure tapping multiple dimensions
The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)
F5 Researchers collected data from a sample of 350 companies on the following
variables
size (measured as number of employees)
Business Strategy (a nominal variable with 2 response options low-cost provider or
differentiator)
HR Strategy (a nominal variable with 2 response categories High commitment or
low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

I2 A study examined the effects of gender and pre-training motivation on the transfer of
training in terms of improved performance for 123 new industrial managers The
training was on supervisory skills and the dependent variable was based on the

J) Meta-analysis
J1 There exist two categories of literature review narrative and quantitative Each
category as typically implemented has certain advantages and disadvantages
Describe the advantages and disadvantages associated with each approach taking
particular care to enumerate the disadvantages associated with quantitative review
Then offer two ways that meta-analysis might be combined with other analytical
techniques to move beyond the focus of bivariate relationships that is typical of meta-
analysis
J2 Schmidt has argued that primary research does not allow one to discover general
scientific laws but that meta-analytic research does What are the arguments in favor
of or against this position In what areas of research (if any) has Schmidts
prediction come closest to coming true
J3 The so-called (by Hunter Schmidt and Jackson 1983) state of the art meta-
analysis method attempts to account for various sources of error that might produce
apparent variation in effect sizes across studies (a) Discuss the three most important
sources of error that meta-analysis addresses (b) Discuss the potential contribution
that a meta-analysis can make to theory building in the organizational sciences (c)
Describe the circumstances that you would consider when deciding whether to
perform a meta-analysis
J4 Meta-analysis has been hailed as a miracle cure and criticized as smoke and
mirrors Explain both sides of the debate and then lay out the role of meta-analysis
as you see it within the time span of your career as an academic To do this use
examples of already written (or yet to be written) articles as models
J5 A frequent criticism of non-quantitative research summaries (literature reviews) is
that researchers do not carefully examine how particular research designs might have
affected the statistical outcomes of the studies included in the literature review Meta-
analysis however allows one to statistically examine such effects Assume you are
conducting a meta-analysis of the relationship between leader behaviors and group
productivity Briefly describe the steps you would take in conducting a meta-
analysis What aspects of the original research designs would you examine in your
meta-analysis What steps would you take in gathering and coding data to enhance
the credibility of your analysis
K) MTMM
K1 One method often used by social scientists to demonstrate the construct validity of
measures is the multi-trait multi-method matrix developed by Campbell and
Fiske (1959) Briefly describe how this matrix is obtained or constructed by a
researcher and then describe how each of the elements of the matrix is used to
demonstrate the reliability andor construct validity of the measure(s)
IC
K2 Describe the logic of the multi-trait multi-method (MTMM) analysis in terms of
the criteria for evaluating the validity of a set of measurement procedures
Interpret the following MTMM in terms of what it might infer about the validity
of the different measurement procedures You may impose any assumptions on
the data you prefer For example you might want to discuss the matrix under the
assumption that traits A B amp C are mutually independent Please justify and

O3 How do exploratory and confirmatory factor analysis differ What are the
advantages and disadvantages of each
O4 Describe the differences between exploratory factor analysis (EFA) and
confirmatory factor analysis (CFA) When would you use one verses another
Are there ways to use EFA in a confirmatory way Can you use CFA in an
exploratory way Also describe the difference in principal components analysis
(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression
O6 The basic factor analysis model can be represented by the matrix algebraic
equation A B = C
(1) What do each of these matrices represent Be specific as to the type of
information in each matrix and its purpose
(2) For what purpose do researchers use factor analysis Explain In the process
provide a very brief description of a study for which factor analysis would be a
useful data analytic technique
O7 Factor analysis is an important statistical technique in organizational research
Describe factor analysis as an analytical tool including the following issues
a the reasons for using factor analysis
b the type of data necessary for using the technique appropriately
c the type of quantitative output that results from applying the technique
d how a researcher would use the output in his or her research

f the important issues and problems in using the technique
P) Structural Equation Models
P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

parameter estimate bias in structural equation modeling Structural Equation

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)
Please comment on these restrictions versus access argument Which side do you
take
What are the strengths of SEM Give some examples
What are the weaknesses of SEM Give some examples

O) General
O1 In your readings research has been described as choices among conflicting goals
(desiderata) For instance when choosing among research strategies a researcher
must choose among the desiderata of precision realism and generalizability The
trade-offs among desiderata occur for all aspects of research that is for the selection
of theories the treatment of independent variables research strategies the selection
of the problem to study rules of evidence for determining the meaningfulness of a
research finding and even the frameworks that describe the research process
Discuss what you see as the major trade-offs for each of the following aspects of
research That is discuss what you see as the major strengths and weaknesses
(advantages and disadvantages) of each aspect
a The trade-offs between internal and external validity
b The manipulation of the independent variable vs the observation of the
independent variable
c Basic vs applied research
3 DESIGNING A RESEARCH STUDY
A) General (Research Design)
3) Why is control so important in research design What are the different ways it can be
achieved (give a brief description of each control method) What are advantages and
disadvantages of each
A1 It has become almost a truism to note that the choice of methods influences theory
and questions data and conclusions (the causal direction might also be reversed)
Briefly discuss how the methods used have influenced research in any two of the
following areas leadership power and politics organization culture organization
justice Compare and contrast as possible Suggest some potentially fruitful
methodological directions for future work in these same topical areas and dont be
shy about reflecting on broader issues of how the field of organizational behavior
constructs its realities Lastly tie your discussion and reflections back to your own
future as a researcher what lessons or guidance do you derive from your
understanding of these issues
A2 Characterize as fully as possible what you see to be the methodological approach or
approaches in strategic management research Is there a dominant method or a wide
variety Discuss the reasons for the situation What are the advantages benefits etc
of the approach(es) in use What assumptions (ontological epistemological
ideological) do they embody Are current efforts ideal or at least adequate Are
there other approaches that could be useful If so how might researchers be
encouraged to use these as well If you see no advantage to more variety in
methodological approach support that point of view
A3 Describe a research question or area of interest to you and why you think it is not
only of interest but significance Using your understanding of research methodology
describe two ways of pursing the question that are as divergent on as many
dimensions as you can imagine Describe the advantages and disadvantages of each
approach How strong a link or fit is there between a research question and a
method
A4 In his 1957 article entitled The two disciplines of scientific psychology Cronbach
discussed the assumptions goals and methods used in experimental methods and
correlational methods in psychology
a According to Cronbach what is the main difference between the two disciplines
b Discuss the strength and weaknesses of each discipline
c What if anything could be done to improve the situation
B) Designing a Research Study
B1 Cook and Campbell describe the experiment as the research design with the
greatest methodological rigor However given the constraints present in most
organizations I-O Psychologists cannot often conduct experiments in applied
settings and must settle for techniques with less control than experiments
Describe a study to investigate the relationship between participation in a
supervisor training program and work performance which could realistically be
conducted in an organization If an experiment is not possible describe how you
would go about maximizing your ability to draw valid conclusions from your
design
B2 The XYZ Co has recently developed a sexual harassment web-based training
program The developers claim the program will cut training time and costs and
will be as effective or more effective than classroom-based sessions They
believe that this will be due to the increased availability of the program and the
ability for participants to review program material on demand Before the XYZ
Co developers launch this product they want you to determine if their claims
have merit Explain how you would design a study for this purpose
B3 Research suggests that demographic diversity improves group creativity but
reduces group efficiency Some argue that demographic diversity is just a proxy
for value and experience diversity and that demographic diversity on its own is
meaningless Design a test to settle this argument
TH
B4 E-mail has become a common form of communication in organizations and is
used for both formal and informal communication Because it has become so
IC
popular some people complain that the frequent use of e-mail leads to
miscommunication because they receive communications in e-mail that should
be accomplished through face-to-face or telephone conversations where there is
an opportunity for interaction You are interested in looking at this
phenomenon You are most interested in describing how e-mail is used for both
formal and informal communication and in examining the effect of the e-mail
use on organizational communication effectiveness Design empirical research
to address those issues
Describe your study in detail thoroughly explaining the research design
sampling plan data collection procedures ethical issues and proposed data
analysis for your research design Be sure to discuss the internal and external
validity of your research Which validity threats are ruled out and which
remain
REMEMBER Be thorough Your research design should demonstrate that you
are a competent researcher who is knowledgeable about the proposed research
methodology or methodologies Therefore be sure that you carefully describe
and give technical explanations for each component of your research
B5 Choose a specific situation involving employee selection eg artists for an
advertising agency (a) What strategy would you use in selecting the selection
measures (b) How would you combine the measures eg which measures
would you combine in a compensatory manner and which is a noncompensatory
manner (c) How would you assume test fairness defining various measures of
the term (d) How would you make final selections (e) How would you
validate your procedure (f) What considerations would enter in if your
company were too small to provide validation data (g) What difference would
it make if you were developing a procedure for deciding whether trainees
should be promoted as opposed to making new hires Please note--emphasize
but do not limit yourself to statistical issues
B6 There is evidence in the marketing literature of a non-monotonic relationship
between the expectations that customers have for retail service and their
eventual level of satisfaction with that service That is as a customers
expectations for service increase so does their eventual service satisfaction --
up to a point After that point the greater the expectations the lower the
eventual satisfaction Develop a hypothesis that includes a moderator variable
that might account for this evidence Give some reasonable rationale for it State
your hypothesis verbally as an equation as a directed graph (circle amp arrow
diagram) and as an X-Y function chart Discuss how it would or would not be
possible or useful to test your hypothesis via a laboratory experiment In your
discussion cover how and why a researcher could (not) manipulate the
independent constructs involved (mode X) whether or not random assignment
to conditions (mode R) is possible (including how may conditions would be
necessary) which alternative constructs could or could not be controlled (mode
K) and which constructs should be measured (mode Y)
B7 Assume you are the chairperson of a committee that must evaluate
undergraduate programs at your university Your task as chairperson is to
devise an approach (a design a research strategy a set of measures) that will
allow you to evaluate undergraduate programs Make sure that your approach
can be used in the future and at other comparable universities When developing
your plan be sure to address at least the following issues
a the type of design you would select Compare and contrast the selected design
with another possible design
b the type of research strategy you would select Compare and contrast with
another possible strategies
c discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
B8 Assume you are an organizational research design expert assigned to the
Strategic Planning Department of a large multi-national manufacturing firm
The Department has developed a new PC-based software package called
STRATPACK The software (and a one-week training course to learn how to
use it) is intended to improve the long-range planning ability of middle and
upper-level managers
Your job as research design expert is to devise research (a design a research
strategy a set of measures) that will allow you to evaluate the effectiveness of
the STRATPACK program Describe a research design for evaluating the
program Make sure that your research approach can be used in the future and at
all sites in the company When developing your plan be sure to address at least
the following issues
a discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
b the type of design you would select (eg a design where you manipulate the
independent variable versus observe the independent variable) Compare and
contrast the selected design with another possible design
c how your design deals with the major forms of validity Be sure to examine at
least internal external and construct validity
B9 Assume you are a consultant hired to evaluate the effectiveness of an industrial
safety program undertaken by a large manufacturing organization The safety
program is a behavioral one that provides rewards such as monetary bonuses or
extra paid vacation days for safety behaviors in terms of accident-free days
weeks etc Your task is to devise an approach (a research strategy a design a
set of measures and a general analysis strategy) that will allow you to evaluate
the safety program Because of the potential for the influence of many
extraneous variables on any safety program it is difficult to design research a
single cross-sectional study than can evaluate the impact of a single safety
program How would you design a study to evaluate the impact of the safety
program When developing your plan be sure to address at least the following
issues
a the type of research strategy you would select Compare and contrast with
another possible strategies
b the type of design you would select Compare and contrast the selected design
with another possible design
c discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
B10 One of the most important areas of research is forecasting of human resources
needs based on strategic positions of organizations For example NY State must
carefully forecast its human resources needs as it proceeds with significant lay-
offs of state employees Future human resources needs are generally evaluated
by either statistical ie regression or simulation or clinical judgment i e
supervisors judgments methods
a Design a single study that addresses the empirical question of whether
statistical or judgmental methods are better for forecasting human resources
needs You may discuss a program of research but please be quite specific in
your description of the first study
b What are the critical methodological issues in doing this kind of research
c What are the critical applied (or practical) issues in doing this research
d Are the issues in b and c related
B11 In the past decade computinginformation technology has changed many
aspects of organizational life For example the technology can make increased
decentralization possible by improving communication between central offices
and field offices Computer networks and word processors can enhance group
empowerment by making it possible for team members to create and edit
written group products quickly even if the individuals are at different locations
Some have argued that computinginformation technology will foster the
paperless productive office nevertheless others argue that the technology only
increases paper and reduces office productivity You are applying to the
National Science Foundation for a grant to conduct research that examines the
impact of computing information technology on organizational decision
processes The NSF application procedure imposes five basic requirements that
your research design must fulfill in order to receive funding Note A very
significant factor affecting NSF grant decisions is a clear demonstration that the
researcher is knowledgeable about the research methodology used Write your
response to each of the following five grant requirements Be sure not only to
respond to the requirement but also to demonstrate your research
competence
1You must design a study that uses two different methods
(interviewobservation survey experiment or quasi-experiment) Describe your
two methods in detail and provide a rationale for the key elements (eg
sampling data collection proposed analysis) of your methods Be sure to
discuss and evaluate the internal and external validity of both methods
2 As part of your research design you must select a conceptual (latent) variable
central to your proposal (use centralization of decision making as your
variable) and describe how you will develop your own measure (You may not
simply use off the shelf instruments)
3 You must describe how you will test for the reliability of the measure
(centralization of decision making) you developed in step 2 The NSF insists
that you describe how you will evaluate both the temporal stability and the
internal consistency of your measure Be sure to discuss what temporal stability
and internal reliability mean and how they are related
4You must describe how you will assess the validity of the measure
(centralization of decision making) you developed in step 2
5 NSF requires a brief statement and defense of the philosophy of science
underlying your research Discuss your position and show how your research
design is consistent with your philosophy
B12 Many organizations in the United States economy have installed some form of
Empowered Teams as an alternative or supplement to traditional bureaucratic
structure Preliminary evidence of the effectiveness of empowered teams
however is mixed--some organizations have claimed success and others have
reported failures The evidence however is predominantly anecdotal--written
for trade magazines by the organizations themselves There are few rigorous
empirical studies assessing the effectiveness of empowered or self-managed
teams You are applying to the United States Department of Labor (USDOL) for
a grant to conduct research that examines the effectiveness of empowered
teams The application procedure of the USDOL imposes three requirements
that your research design must fulfill in order to receive funding Write your
response to each of the three grant requirements The importance of each section
is implied by the evaluation points allocated by the USDOL to each of the three
requirements given in parentheses
1 (50 points) Your study design for assessing Empowered Team effectiveness
must use two different methods (interview observation archival analysis
survey simulation experiment or quasi-experiment) Describe in detail and
thoroughly explain the sampling plan instrumentation data collection
procedures and proposed data analyses for both methods Be sure to discuss the
internal and external validity of both methods and how the two methods
complement one another
2 (30 points) As part of your research design you must select one conceptual
(latent) variable central to your proposal and describe how you will develop
your own operationalization of the measure (You may not simply use off the
shelf instruments) Use the concept of group morale to demonstrate your
operationalization methodology Be sure to explain very explicitly to the
USDOL how you will assess the validity and reliability of the group morale
measure you are developing
3 (20 points) The USDOL traditionally has funded research conducted only
within the general paradigm of logical positivism but now is more open to other
research paradigms as well Your grant proposal must provide a statement and
defense of the explicit philosophy of science underlying your research Describe
your philosophy of science and show how your research design is consistent
with your philosophy
REMEMBER Be thorough You not only must design effective research but
you also must demonstrate to the USDOL that you are a competent researcher
It is absolutely vital to the USDOL that the principal researcher is
knowledgeable about the proposed research methodologies Therefore be sure
that you always carefully describe and give technical explanations for each
component of your research design and explain all technical terms (eg
Cronbach alpha KR-20 Likert scale)
B13 Assume that you are working as part of a research team that is responding to a
RFP (Request for Proposals) from a funding agency for research on work
socialization and newcomer adjustment The RFP calls for rigorous field
research that tests the effectiveness of theory-based interventions aimed at
facilitating the adjustment of new organizational members to complex andor
stressful work conditions The major goal of your teams research is to test the
effectiveness of a self-regulation intervention which trains newcomers to
identify and use relevant social information and cues to regulate work behavior
Your group hypothesizes that self-regulation training will be more effective
than other common treatments or interventions (eg realistic job previews
institutionalized socialization tactics)
You have been included in the team because of your methodological expertise
Your role is to design a rigorous field experiment or quasi-experiment to test he
effectiveness of the self-regulation training program REMEMBER THE
MAJOR CRITERION FOR FUNDING IS THE RIGOR OF THE RESEARCH
DESIGN Design a field study to include in the grant proposal Your proposal
should contain the following two sections
1 Study Design Construct and describe in detail an experimental or quasi-
experimental design to test the effectiveness of your intervention Describe in
detail the experimental groups (including how they will be constructed) the
research setting the sampling plan for study participants the treatment
manipulation and the data collection procedures Also indicate any control or
nuisance variables that may be measured
After describing the procedures write a justification of the design What threats
to validity does it rule out or limit and what threats to validity remain
II Measurement Describe the steps you would take to achieve valid and
reliable measure of the latent (conceptual) variable worker adjustment Your
team feels that as part of the proposal you must develop an original
operationalization of adjustment (thus you cannot simply use existing off the
shelf measures) Indicate in adequate detail how you would operationalize the
measure and indicate how you would demonstrate reliability and validity
B14 In describing their notion of the collective mind Karl E Weick and Karlene H
Roberts note Our focus is at once on individuals and the collective since only
individuals can contribute to a collective mind but a collective mind is distinct
from an individual because it inheres in the pattern of interrelated activities
among many people (p 360) Collective mind is not indexed by within-group
similarity of attitudes ideas or activities A collective mind is one in which
many people or many groups integrate their different attitudes ideas and
activities heedfully As Weick and Roberts note People act heedfully when
they act more or less carefully critically consistently purposefully attentively
studiously vigilantly conscientiously pertinaciously (p 361)
The idea of the collective mind as heedful interrelating is developed in the
following excerpt When people make efforts to interrelate these efforts can
range from heedful to heedless The more heed reflected in a pattern of
interrelations the more developed the collective mind and the greater the
capability to comprehend unexpected events that evolve rapidly in unexpected
ways When we say that a collective mind comprehends unexpected events we
mean that heedful interrelating connects sufficient know-how to meet situational
demands For organizations concerned with reliability those developments
often consist of unexpected non-sequential interaction (p366)
An example of heedful interrelating occurs as a pilot lands herhis aircraft on the
deck of an aircraft carrier The pilot does not actually land She is recovered
A recovery is an interrelated set of activities among air traffic controllers
landing signal officers the control tower navigators deck hands the helmsman
driving the ship etc These activities can be interrelated more or less heedfully
depending on the care with which the different units contribute represent the
situation and subordinate their activities to the single purpose of successful
recovery (p 363)
You are to design a two-part study
Part I You are to design a measurement study which assesses heedful
interrelating (ie collective mind) with a quantitative measure in a replication
of an aircraft carrier flight deck or other situation of your choosing Describe
your research strategies including operationalization of the variable selection of
the sample subjects data collection data analysis and so on for the purpose of
developing a measure of heedful interrelating
Part II Using the measurement tool developed in Part I and any other tools as
needed describe how you would design a study which would compare heedful
interrelating across organizations Choose at least one macro-organizational
variable (eg technology environment) as your basis of comparison Here you
must describe how you would make your selection of organizations to be
compared your data collection procedure data analysis and so on
B15 Many organizations in the United States have installed cross-functional teams to
counteract the silo mentality of traditional bureaucratic structure Preliminary
evidence of the effectiveness of cross-functional teams however is mixed --
some organizations have claimed success and others have reported failures The
evidence moreover is predominantly anecdotal--written for trade magazines by
the organizations themselves Since there have been few rigorous empirical
field studies assessing the effectiveness of cross functional teams the National
Science Foundation has decided to fund research on the topic
Assume that you are submitting a research proposal to NSF for a grant to
research the effectiveness of cross-functional teams Describe in detail and
thoroughly explain the research design sampling plan data collection
procedures ethical issues and proposed data analysis for your research design
Be sure to discuss the internal and external validity of your research Which
validity threats are ruled out and which remain NSF also requires that you
provide a statement and defense of the explicit philosophy of science underlying
your research Describe your philosophy of science and discuss how your
research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but
you must also demonstrate to NSF that you are a competent researcher It is
absolutely vital to NSF that the principal researcher (you) is knowledgeable
about the proposed research methodologies Therefore be sure that you always
carefully describe and give technical explanations for each component of your
research design and explain all technical terms (eg Cronbach alpha KR-20
Likert scale)
B16 Assume that you are submitting a research proposal to the Department of
Commerce (DoC) for a grant to research the effectiveness of virtual work teams
A virtual work team is a leaderless collection of individuals who are
geographically separate from one another and share their expertise using
internet media such as a listserver or Lotus notes The DoC requires that the
researcher use both qualitative and quantitative methods to gather data Describe
in detail and thoroughly explain the research design sampling plan data

5 MEASUREMENT
A) Measurement Terms
A1 There are four levels of measurement rigor in management research Discuss each
one What properties do measurements at each level have (ie how much
information do the numbers from each level of measurement convey) How can the
numbers be changed (transformed) and still retain the properties of their
measurement level Pick one construct from a favorite research domain and give an
example of an operationalization of that construct at each of the four levels of
measurement rigor (provide arguments about why you think those examples reflect
each level) Lastly treat each examplelevel as a dependent variable in some
statistical analysis Given an example of a statistical technique appropriate for
analyzing data at that level of measurement rigor
A2 Define (and discuss important features or issues concerning) the following
constructs measurement (Define any six terms)
1 Construct validity 6 Item analysis
2 Likert scaling 7 Semantic differential
3 Cronbachs alpha 8 True score
4 Unobtrusive (trace) measurement 9 Generalizability theory
5 Interval scale 10 Criterion-related validity
11 Sociometric choice measures

estate agents self-assessment of performance Since there is no existing
measurement available you have to develop the instrument by yourself
Describe how you would develop the measurement assuming that you have no
idea of how many dimension the construct has
b) Suppose you have developed an instrument consists of 20 questions
measuring 4 dimensions (5 items per dimension) from (a) You collected data
from another 300 real estate agents to validate your instrument Explain how
TH
you would use structural equations model (SEM) to examine the reliability and
validity of the instrument What are other concerns about reliability and validity
that are not addressed by this approach
B2 The research and business world have been fascinated with the concept of
organizational culture However operationalizing this construct has been a
difficult task Discuss the ways in which the construct has been operationalized
(eg technique static v dynamic sample selection generalizability) Critically
analyze each of these methodologies Then choose a methodology you would
use to examine organizational culture and defend your choice Describe how
you would study culture and what more would be known about culture as a
result of your study
B3 Suppose you are setting out to develop a new measure of a construct You want
this measure to be used in survey research and you want to establish its validity
and reliability Your goal is to have at the end of the process a measure that is
defensible and likely to be widely accepted by other researchers studying that
construct What steps would you take to conduct such a program of research
For each step explain the purpose of that step explain why that step is
important explain what methods and statistical procedures you would employ at
each step and explain what evidence you would hope to gather at each step
B4 Assume you are interested in constructing a new measure of (fill in with a
relevant variable from your field) Detail the major concerns that need to be
addressed and the steps that need to be taken in working toward validating this
new measure
B5 Assume that you recently read an article on workplace violence which you
found very interesting The authors argued that one of the predictors of
workplace violence was a construct called propensity to be violent and used a
one-item measure as follows How likely are you to become violent when
provoked You had serious doubts about the authors measure and decided to
develop your own
(a) How would you go about developing items to measure propensity to be
violent
(b) How would you determine whether the instrument was reliable
How would you determine whether the instrument was valid
B6 A concern in organizations is retirement of baby boomers within the next 5 -
10 years This concern is focused on the loss of older employees with skills
critical to the core business functions of organizations In order to continue to
have employees with those critical skills it seems necessary to retrain some
older workers However past practice in most organizations has been not to
retrain older workers for a variety of reasons mostly financial A researcher
working for the Human Resources Department of a large corporation - 13500
employees in 12 different plant locations - hypothesizes that the major reason
for not retraining older workers is ingrained in the culture of the corporation
IC
The researcher feels that older workers are not as highly valued as younger
workers in terms of their potential usefulness after retraining The researcher
searched the literature but found nothing in the existing literature to measure
the cultural value construct What should the researcher do to establish a reliable
and valid self-administered paper and pencil measure of this construct namely
the value of retraining older workers

determine if your operationalization is valid
B8 Organizational researchers have several strategies available to them for
gathering information (eg self-report measures archival measures direct
observation and trace measures) Assume that you are going to conduct
empirical research to assess the role that the structure of the organization plays
in determining the level of organizational effectiveness Briefly review the
strengths and weaknesses of the basic strategies (that is self-report measures
archival measures direct observation and trace measures) for measuring
organizational effectiveness Next describe and justify the steps you would
take to develop an operationalization of the concept of organizational
effectiveness What standards and procedures would you use to determine if
your operationalization is valid
B9 One of the most important topics of recent research has been stress in the work
place One of the most important problems with understanding this literature is
the varying definitions and measurement of this construct Suppose you had
decided to investigate the relationship between stress at the work place and dual
career family happiness
a Since there are multiple ways to measure stress in the work place describe
two ways to do this Hint - avoid using two self-report measures
b Describe how you would decide on the best single measure In doing so
describe the steps you would take in evaluating your measure Be sure to define
your meaning of validity and reliability It is important that your measure have
all the necessary psychometric characteristics so that other scientist can trust the
results of your research

measure of stress at work with other measures of this construct How would you
do that

impact of interpersonal trust on organizational decision making Describe and
justify the steps you might follow to develop an operationalization of the
interpersonal trust concept

operationalization is valid and reliable
How would you assess the construct validity of such a measure
Discuss issues concerning the level of observation of your measure and level of
analysis of the data
B13 Assume you are interested in developing a new scale to measure construct X
Further assume that you have used previous literature and your own conceptual
development to delineate 2 dimensions of X specifically XF1 and XF2
Describe the steps you would go through in developing testing and evaluating
this new scale With regard to testing and evaluating be sure to consider the
role of factor analysis (both exploratory and confirmatory) and item analysis
Also you will want to make sure that your new multidimensional scale shows
evidence of validity (several kinds) and reliability so be sure to examine these
issues and explain how specific information gathered from the above testing
contributes to these concerns

measure
C9 Define reliability Name some methods of calculating reliability How well do
these methods map up with the definition of reliability What is the impact of the
number of test items and sample size on Chronbachs alpha and why would this
effect occur or not occur (Note Do NOT discuss inter-rater reliability)
C10 Schmidt and Hunter (1996) described several types of measures typically used in
organizational research and identified the type(s) of measurement error affecting
each of them in various situations For each measure below indicate the types of
error and sources of error that are most likely to affect it Then indicate what
could be done to reduce errors of measurement andor what can be done to
control for errors statistically

worker)
d Aptitude tests taken as part of the hiring process
C11 Suppose you had conducted research on the relationship between organizational
commitment and rigidity of organizational structure in 200 firms Your measure
of rigidity was based on number of organizational authority levels and the degree
to which written organizational rules existed and defined role behaviors for
employees Thus an organization with a large number of organizational levels
and specific written policies defining appropriate role behaviors for employees
would score high on rigidity of organizational structure After analyzing your
data you find that there is a statistically significant negative correlation between
commitment and rigidity which is consistent with your hypothesis However the
reliabilities for your two measures are
(1) commitment = 23 (2) rigidity = 83
How should you interpret your results What could you do to fix this situation
Describe the specific steps (in order) you would follow to develop a more
reliable measure of commitment

data
(e) Provide some ideas for avoiding the need to aggregate in group-level research

research literature This type of research raises many issues and presents many
challenges in terms of designing the research measuring variables and collecting
and analyzing the data Assume that you are interested in aggregating data (eg
from the individual to the group or from the firm to the industry) for one or more
variables What are the major issues you will need to deal with
D3 A researcher wants to measure organizational climate for continuous learning
Organizational climate is operationalized as a shared consensual aspect of the
organization -- the shared perception among employees that the organization values
and supports continuous learning Describe how you would measure organizational
climate in this case Specify (a) the level (ie individual group organization) at
which the construct exists (b) the level at which you would measure the construct
and (c) the procedures that you would use to establish that measurement is aligned
with theory (ie the construct validity of the measure)
E) General (Measurement)
E1 Studies in organizational behavior research often rely on single-item measures of
key constructs The use of single-item measures has long been criticized based
on the premise that single-item measures are unreliable However Wanous
(Wanous amp Hudy 2001 Wanous amp Reichers 1996 Wanous Reichers amp Hudy
1997) has recently argued that single-item measures can exhibit adequate
reliability Wanous based this conclusion on a procedure for estimating the
reliability of single-item measures using the classic formula for correction for
attenuation Subsequent studies have yielded mixed results regarding the
conclusions of Wanous (eg Loo amp Kells 1998 Nagy 2002) and the veracity
of the perspective advocated by Wanous remains in question Summarize and
assess the arguments for and against the use of single-item measures and
evaluate the procedure and evidence offered by Wanous regarding the reliability
of single-item measures Based on your assessment and evaluation develop
recommendations regarding the use of single-item measures in organizational
behavior research

E2 Ipsative measures have become prevalent in organizational behavior research
Ipsative measures ask respondents to answer questions relative to one another
such that the scores for all questions sum to the same constant for all respondents
Examples of ipsative measures include rankings Q-sorts and the allocation of a
fixed number of points (eg 100) across a set of response options Ipsative
measures may be contrasted with absolute measures which ask respondents to
answer questions independently from one another Absolute measures are
exemplified by rating scales using an interval or ratio numeric response format
The relative merits of ipsative and absolute measures have been debated for
decades (eg Cornwell amp Dunlap 1994 Hicks 1970 Johnson Wood amp
Blinkhorn 1988 Saville amp Wilson 1991 1992) yet the fundamental issues
underlying this debate have not been adequately addressed in organizational
behavior research For example measures of organizational culture and values
are often ipsative and some researchers advocate these measures over absolute
measures (eg Meglino amp Ravlin 1987 OReilly Chatman amp Caldwell 1991
Ravlin amp Meglino 1987 see also Rokeach amp Ball-Rokeach 1989) Review the
relative merits of absolute and ipsative measures Based on your review which
form of measurement is most appropriate and why Do your conclusions depend
on the construct being measured If so what types of constructs are best suited to
ipsative measures and what types are best suited to absolute measures Next
apply your conclusions to the measurement of culture and values in
organizations What specific arguments have been advanced in favor of ipsative
measures of culture and values How sound are these arguments Should ipsative
measures be used in the study of organizational culture and values If not how
can absolute measures of culture and values be developed that address the
concerns voiced by advocates of ipsative measures Provide a specific example
of the type of measure you would propose

facets of a concept Although such measures are prevalent and in some cases are
advocated (eg Law et al 1998 1999) they can present a variety of conceptual
and methodological problems Describe the specific problems associated with
measures that use items representing different facets of a concept Compare these
problems with the purported advantages of such measures Conclude by

E5 Suppose Roberta Von Eisenbrick is a researcher interested in the consequences of
AFFECTIVE CONFLICT (AC) in decision-making teams She gets access to a
variety of outcomes assessment committees at each of 87 different schools in
the Dallas Independent School District and gains permission to tape-record two
of their meetings (one in February and one in March) Such committees have
been formed to develop quantitative ways to track pursuit of school goals and
provide accountability to local and state governments These are often divisive
teams with heated meetings because what gets assessed is what usually gets
rewarded After both of these meetings the committee members each
fill out a short questionnaire that contains 20 Likert-type items measuring how
much AC occurred (eg People in our group often get angry with each other)
The individual scores are summed across items then averaged across team
members to come up with a group-level AC score for each of the 87 2
meetings The same procedures are followed for a 5-item measure of Group
Cohesiveness (GC) which is predicted to be reduced by higher levels of AC
Roberta also listens to every tape and from her expert judgment she rates each
groups meetings on the same 20 items Those 20 ratings are summed for each of
the 87 2 meetings Now Roberta is interested in evaluating her measure She
wants it to have excellent psychometric properties including reliability and
construct validity

(a) Please define both of these terms (b) Sketch a conceptual model to show how
each relates to main effects (c) Using variables of your choice please write
hypotheses to reflect both (d) Explain how each is tested analytically
D2 Discuss moderators and mediators Provide an example of how (1) a moderating
variable influences the relationship between the independent and dependent
variable and how (2) a mediating variable influences the relationship between
the independent and dependent variable Describe how you would test for both
moderation and mediation using regression
D3 Many theories in organizational research predict that the effects of one variable
on another are moderated by a third variable Such moderator effects are
typically tested by entering the product of two variables as a predictor after
controlling for the two variables that constitute the product Several researchers
have pointed out that this product is often highly correlated with the squares of
the two constituent variables and have suggested that moderating effects may be
tested after controlling not only for the two constituent variables but also their
squares (eg Cortina 1993 Ganzach 1998 Lubinski amp Humphreys 1990
MacCallum amp Mar 1995) Discuss the strengths and weaknesses of this
approach as compared to methods that use only the product term and its
constituent variables Conclude with recommendations as to when and under
what conditions organizational researchers should test moderator effects with the
squares of the constituent variables in the equation

D4 Assume you are interested in studying relationships amongst three variables X
Y and Z Your first hypothesis posits Z as a mediator of the relationship between
X and Y Your second hypothesis posits Z as a moderator of the relationship
between X and Y Draw the figures depicting each of these hypothesized
relationships and describe (make sure to write regression equations) how you
would test each of these hypotheses
D5 The amount of time and effort that the average person pours into his or her job
has risen steadily over the last two decades such that the average person now is
working one more week per year than the average person in the mid 1970s This
steady increase has fueled research interest in the construct of Job Burnout (JB)
which is an emotional and physical exhaustion associated with ones work
Organizational Stress (OS) the perception of greater demands than available
resources in ones work environment is thought to be one of the chief
antecedents of JB However time spent under OS is thought to make its affects
on JB accumulate or worsen Work Role Withdrawal (WRW) the avoidance of
responsibilities or the deliberate reduction of inputs to ones job is believed to be
the chief consequence of JB
a Formally state these ideas as verbal hypotheses as equations and as a complex
directed graph (circle amp arrow diagram)
b Conceptually what is a mediator Define the term and identify the mediator in
your hypotheses in (a) What elements or steps in a study design (not statistics)
that would be helpful for detecting the mediating relationship that was proposed

subdomains of management Further demonstrate your understanding of
moderator variables by picking which variable in (a) is the moderator Show the
moderating relationship in an X-Y (or multi-layered) chart Again what elements
or steps in a study design (not statistics) would be helpful for detecting the
moderating effect implied above

reader understand the results of the statistical tests you report and the nature of your
sample (Hint this can be presented in the form of a table)
2 describing and defending your choice of appropriate statistical tests of the
hypotheses and the steps that you would go through in carrying out these tests
3 making up and reporting results of these tests that are consistent with your
descriptive statistics and with any information in the rest of the article about the
results found (Hint this can be presented in the form of a table)
4 describing how well these results provide support for the hypotheses You
may want to note any relevant threats to validity here
Be sure to state any assumptions you make
F2 Assume that the Personnel Manager of a local firm Ms B dFlandres hired you to
analyze some data that her assistants had collected over the past several years The
data consist of (a) job performance ratings that were made in June of 1990 and (b)
scores on 25 predictor variables (eg measures of education job experience job
tenure job aptitude personality) that were measured when the individuals were hired
(between April 1987 and May 1988) She had data from only the 110 subjects (60
males and 50 females) who were hired during the period and were still employed by
the firm One objective of your analysis (analyses) is to determine how well the
performance criterion can be predicted by the predictors What strategy would you
use in analyzing the data Describeexplain (b) Is sample size an issue for your
analyses Explain If it is what will you do to deal with problems stemming from
sample size Assume that no additional data can be collected at this time (c) Some
preliminary analyses that you do reveal that five of the predictor variables correlate
(zero-order basis) about 75 with one another Will this influence the analyses that
you use Will it influence the validity of conclusions derived from your proposed
analyses (d) Ms dFlandres is interested in knowing if the predictor variables are
equally effective in predicting the job success of males and females What analysis
or analyses would you do to deal with this issue
F3 Assume that you have been provided with data on 12 conceptually distinct variables
that are moderately correlated with one another at the empirical level The data are
from students in four different college majors ie astronomy (A) biology (B)
criminology (C) and demography (D) The 12 measured variables fall into the
general categories of mental health (tension emotional withdrawal hallucinations
guilt feelings blunted affect and suspiciousness) and job satisfaction (work itself
supervision co-workers pay promotion prospects and working conditions) Your
task is to determine if the individuals in the four college majors differ from one
another on the 12 measured variables
(a) What statistical technique(s) would you use to test for group differences
Explain Be specific about the procedures(s) that you would use
(b) What statistical estimate would you use to estimate the extent to which the
groups differ from one another Be specific
F4 The following statistical table published in a recent issue of Work amp Occupations
was taken from an article discussing variables influencing resistance and citizenship
behaviors in the workplace Resistance behaviors include playing dumb withholding
effort work avoidance subverting particular managers and sabotage Citizenship
behaviors include cooperation engaging in peer training use of insider knowledge to
facilitate production commitment to organizational goals giving extra effort freely
Both measures are global constructs aggregated to the interval level and
standardized
The table reports the results of a series of ordinary least squares regression equations
with standardized coefficients Explain the meaning of the statistics presented What
do these statistics tell us generally about the relationship between resistance
behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows
Anomie Index -standardized interval level measure tapping multiple dimensions
The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)
F5 Researchers collected data from a sample of 350 companies on the following
variables
size (measured as number of employees)
Business Strategy (a nominal variable with 2 response options low-cost provider or
differentiator)
HR Strategy (a nominal variable with 2 response categories High commitment or
low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

I2 A study examined the effects of gender and pre-training motivation on the transfer of
training in terms of improved performance for 123 new industrial managers The
training was on supervisory skills and the dependent variable was based on the
appraisal of the supervisors performance before the training and three months after
the training The performance appraisal data were collected for research purposes
only and resulted in a total transfer score from 1 to 25 with 1 being low Pre-training
motivation was based on a 12 item Likert scale with an alpha of 86 Two groups

mirrors Explain both sides of the debate and then lay out the role of meta-analysis
as you see it within the time span of your career as an academic To do this use
examples of already written (or yet to be written) articles as models
J5 A frequent criticism of non-quantitative research summaries (literature reviews) is
that researchers do not carefully examine how particular research designs might have
affected the statistical outcomes of the studies included in the literature review Meta-
analysis however allows one to statistically examine such effects Assume you are
conducting a meta-analysis of the relationship between leader behaviors and group
productivity Briefly describe the steps you would take in conducting a meta-
analysis What aspects of the original research designs would you examine in your
meta-analysis What steps would you take in gathering and coding data to enhance
the credibility of your analysis

O1 Contrast Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis
(CFA) Give an example for the appropriate use of each of the above analyses
What is the role of theory in the two factor analyses
IC
O2 Compare and contrast Exploratory Factor Analysis (EFA) with Confirmatory TH

assumptions usage and limitations
O3 How do exploratory and confirmatory factor analysis differ What are the
advantages and disadvantages of each
O4 Describe the differences between exploratory factor analysis (EFA) and
confirmatory factor analysis (CFA) When would you use one verses another
Are there ways to use EFA in a confirmatory way Can you use CFA in an
exploratory way Also describe the difference in principal components analysis
(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression

information in each matrix and its purpose
(2) For what purpose do researchers use factor analysis Explain In the process
provide a very brief description of a study for which factor analysis would be a
useful data analytic technique

P) Structural Equation Models
P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)
Please comment on these restrictions versus access argument Which side do you
take
What are the strengths of SEM Give some examples
What are the weaknesses of SEM Give some examples

B) Designing a Research Study
B1 Cook and Campbell describe the experiment as the research design with the
greatest methodological rigor However given the constraints present in most
organizations I-O Psychologists cannot often conduct experiments in applied
settings and must settle for techniques with less control than experiments
Describe a study to investigate the relationship between participation in a
supervisor training program and work performance which could realistically be
conducted in an organization If an experiment is not possible describe how you
would go about maximizing your ability to draw valid conclusions from your
design
B2 The XYZ Co has recently developed a sexual harassment web-based training
program The developers claim the program will cut training time and costs and
will be as effective or more effective than classroom-based sessions They
believe that this will be due to the increased availability of the program and the
ability for participants to review program material on demand Before the XYZ
Co developers launch this product they want you to determine if their claims
have merit Explain how you would design a study for this purpose
B3 Research suggests that demographic diversity improves group creativity but
reduces group efficiency Some argue that demographic diversity is just a proxy
for value and experience diversity and that demographic diversity on its own is
meaningless Design a test to settle this argument
TH
B4 E-mail has become a common form of communication in organizations and is
used for both formal and informal communication Because it has become so
IC
popular some people complain that the frequent use of e-mail leads to
miscommunication because they receive communications in e-mail that should
be accomplished through face-to-face or telephone conversations where there is
an opportunity for interaction You are interested in looking at this
phenomenon You are most interested in describing how e-mail is used for both
formal and informal communication and in examining the effect of the e-mail
use on organizational communication effectiveness Design empirical research
to address those issues
Describe your study in detail thoroughly explaining the research design
sampling plan data collection procedures ethical issues and proposed data
analysis for your research design Be sure to discuss the internal and external
validity of your research Which validity threats are ruled out and which
remain
REMEMBER Be thorough Your research design should demonstrate that you
are a competent researcher who is knowledgeable about the proposed research
methodology or methodologies Therefore be sure that you carefully describe
and give technical explanations for each component of your research
B5 Choose a specific situation involving employee selection eg artists for an
advertising agency (a) What strategy would you use in selecting the selection
measures (b) How would you combine the measures eg which measures
would you combine in a compensatory manner and which is a noncompensatory
manner (c) How would you assume test fairness defining various measures of
the term (d) How would you make final selections (e) How would you
validate your procedure (f) What considerations would enter in if your
company were too small to provide validation data (g) What difference would
it make if you were developing a procedure for deciding whether trainees
should be promoted as opposed to making new hires Please note--emphasize
but do not limit yourself to statistical issues
B6 There is evidence in the marketing literature of a non-monotonic relationship
between the expectations that customers have for retail service and their
eventual level of satisfaction with that service That is as a customers
expectations for service increase so does their eventual service satisfaction --
up to a point After that point the greater the expectations the lower the
eventual satisfaction Develop a hypothesis that includes a moderator variable
that might account for this evidence Give some reasonable rationale for it State
your hypothesis verbally as an equation as a directed graph (circle amp arrow
diagram) and as an X-Y function chart Discuss how it would or would not be
possible or useful to test your hypothesis via a laboratory experiment In your
discussion cover how and why a researcher could (not) manipulate the
independent constructs involved (mode X) whether or not random assignment
to conditions (mode R) is possible (including how may conditions would be
necessary) which alternative constructs could or could not be controlled (mode
K) and which constructs should be measured (mode Y)
B7 Assume you are the chairperson of a committee that must evaluate
undergraduate programs at your university Your task as chairperson is to
devise an approach (a design a research strategy a set of measures) that will
allow you to evaluate undergraduate programs Make sure that your approach
can be used in the future and at other comparable universities When developing
your plan be sure to address at least the following issues
a the type of design you would select Compare and contrast the selected design
with another possible design
b the type of research strategy you would select Compare and contrast with
another possible strategies
c discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
B8 Assume you are an organizational research design expert assigned to the
Strategic Planning Department of a large multi-national manufacturing firm
The Department has developed a new PC-based software package called
STRATPACK The software (and a one-week training course to learn how to
use it) is intended to improve the long-range planning ability of middle and
upper-level managers
Your job as research design expert is to devise research (a design a research
strategy a set of measures) that will allow you to evaluate the effectiveness of
the STRATPACK program Describe a research design for evaluating the
program Make sure that your research approach can be used in the future and at
all sites in the company When developing your plan be sure to address at least
the following issues
a discuss how your design and approach deals with the major forms of validity

independent variable versus observe the independent variable) Compare and
contrast the selected design with another possible design
c how your design deals with the major forms of validity Be sure to examine at
least internal external and construct validity
B9 Assume you are a consultant hired to evaluate the effectiveness of an industrial
safety program undertaken by a large manufacturing organization The safety
program is a behavioral one that provides rewards such as monetary bonuses or
extra paid vacation days for safety behaviors in terms of accident-free days
weeks etc Your task is to devise an approach (a research strategy a design a
set of measures and a general analysis strategy) that will allow you to evaluate
the safety program Because of the potential for the influence of many
extraneous variables on any safety program it is difficult to design research a
single cross-sectional study than can evaluate the impact of a single safety
program How would you design a study to evaluate the impact of the safety
program When developing your plan be sure to address at least the following
issues
a the type of research strategy you would select Compare and contrast with
another possible strategies
b the type of design you would select Compare and contrast the selected design
with another possible design
c discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
B10 One of the most important areas of research is forecasting of human resources
needs based on strategic positions of organizations For example NY State must
carefully forecast its human resources needs as it proceeds with significant lay-
offs of state employees Future human resources needs are generally evaluated

B11 In the past decade computinginformation technology has changed many
aspects of organizational life For example the technology can make increased
decentralization possible by improving communication between central offices
and field offices Computer networks and word processors can enhance group
empowerment by making it possible for team members to create and edit
written group products quickly even if the individuals are at different locations
Some have argued that computinginformation technology will foster the
paperless productive office nevertheless others argue that the technology only
increases paper and reduces office productivity You are applying to the
National Science Foundation for a grant to conduct research that examines the
impact of computing information technology on organizational decision
processes The NSF application procedure imposes five basic requirements that
your research design must fulfill in order to receive funding Note A very
significant factor affecting NSF grant decisions is a clear demonstration that the
researcher is knowledgeable about the research methodology used Write your
response to each of the following five grant requirements Be sure not only to
respond to the requirement but also to demonstrate your research
competence
1You must design a study that uses two different methods
(interviewobservation survey experiment or quasi-experiment) Describe your
two methods in detail and provide a rationale for the key elements (eg
sampling data collection proposed analysis) of your methods Be sure to
discuss and evaluate the internal and external validity of both methods
2 As part of your research design you must select a conceptual (latent) variable
central to your proposal (use centralization of decision making as your
variable) and describe how you will develop your own measure (You may not
simply use off the shelf instruments)
3 You must describe how you will test for the reliability of the measure
(centralization of decision making) you developed in step 2 The NSF insists
that you describe how you will evaluate both the temporal stability and the
internal consistency of your measure Be sure to discuss what temporal stability
and internal reliability mean and how they are related
4You must describe how you will assess the validity of the measure
(centralization of decision making) you developed in step 2
5 NSF requires a brief statement and defense of the philosophy of science
underlying your research Discuss your position and show how your research
design is consistent with your philosophy
B12 Many organizations in the United States economy have installed some form of
Empowered Teams as an alternative or supplement to traditional bureaucratic
structure Preliminary evidence of the effectiveness of empowered teams
however is mixed--some organizations have claimed success and others have
reported failures The evidence however is predominantly anecdotal--written
for trade magazines by the organizations themselves There are few rigorous
empirical studies assessing the effectiveness of empowered or self-managed
teams You are applying to the United States Department of Labor (USDOL) for
a grant to conduct research that examines the effectiveness of empowered
teams The application procedure of the USDOL imposes three requirements
that your research design must fulfill in order to receive funding Write your
response to each of the three grant requirements The importance of each section
is implied by the evaluation points allocated by the USDOL to each of the three
requirements given in parentheses
1 (50 points) Your study design for assessing Empowered Team effectiveness
must use two different methods (interview observation archival analysis
survey simulation experiment or quasi-experiment) Describe in detail and
thoroughly explain the sampling plan instrumentation data collection
procedures and proposed data analyses for both methods Be sure to discuss the
internal and external validity of both methods and how the two methods
complement one another
2 (30 points) As part of your research design you must select one conceptual
(latent) variable central to your proposal and describe how you will develop
your own operationalization of the measure (You may not simply use off the
shelf instruments) Use the concept of group morale to demonstrate your
operationalization methodology Be sure to explain very explicitly to the
USDOL how you will assess the validity and reliability of the group morale
measure you are developing
3 (20 points) The USDOL traditionally has funded research conducted only
within the general paradigm of logical positivism but now is more open to other
research paradigms as well Your grant proposal must provide a statement and
defense of the explicit philosophy of science underlying your research Describe
your philosophy of science and show how your research design is consistent
with your philosophy
REMEMBER Be thorough You not only must design effective research but
you also must demonstrate to the USDOL that you are a competent researcher
It is absolutely vital to the USDOL that the principal researcher is
knowledgeable about the proposed research methodologies Therefore be sure
that you always carefully describe and give technical explanations for each
component of your research design and explain all technical terms (eg
Cronbach alpha KR-20 Likert scale)
B13 Assume that you are working as part of a research team that is responding to a
RFP (Request for Proposals) from a funding agency for research on work
socialization and newcomer adjustment The RFP calls for rigorous field
research that tests the effectiveness of theory-based interventions aimed at
facilitating the adjustment of new organizational members to complex andor
stressful work conditions The major goal of your teams research is to test the
effectiveness of a self-regulation intervention which trains newcomers to
identify and use relevant social information and cues to regulate work behavior
Your group hypothesizes that self-regulation training will be more effective
than other common treatments or interventions (eg realistic job previews
institutionalized socialization tactics)
You have been included in the team because of your methodological expertise
Your role is to design a rigorous field experiment or quasi-experiment to test he
effectiveness of the self-regulation training program REMEMBER THE
MAJOR CRITERION FOR FUNDING IS THE RIGOR OF THE RESEARCH
DESIGN Design a field study to include in the grant proposal Your proposal
should contain the following two sections
1 Study Design Construct and describe in detail an experimental or quasi-
experimental design to test the effectiveness of your intervention Describe in
detail the experimental groups (including how they will be constructed) the
research setting the sampling plan for study participants the treatment
manipulation and the data collection procedures Also indicate any control or
nuisance variables that may be measured
After describing the procedures write a justification of the design What threats
to validity does it rule out or limit and what threats to validity remain
II Measurement Describe the steps you would take to achieve valid and
reliable measure of the latent (conceptual) variable worker adjustment Your
team feels that as part of the proposal you must develop an original
operationalization of adjustment (thus you cannot simply use existing off the
shelf measures) Indicate in adequate detail how you would operationalize the
measure and indicate how you would demonstrate reliability and validity
B14 In describing their notion of the collective mind Karl E Weick and Karlene H
Roberts note Our focus is at once on individuals and the collective since only
individuals can contribute to a collective mind but a collective mind is distinct
from an individual because it inheres in the pattern of interrelated activities
among many people (p 360) Collective mind is not indexed by within-group
similarity of attitudes ideas or activities A collective mind is one in which
many people or many groups integrate their different attitudes ideas and
activities heedfully As Weick and Roberts note People act heedfully when
they act more or less carefully critically consistently purposefully attentively
studiously vigilantly conscientiously pertinaciously (p 361)
The idea of the collective mind as heedful interrelating is developed in the
following excerpt When people make efforts to interrelate these efforts can
range from heedful to heedless The more heed reflected in a pattern of
interrelations the more developed the collective mind and the greater the
capability to comprehend unexpected events that evolve rapidly in unexpected
ways When we say that a collective mind comprehends unexpected events we
mean that heedful interrelating connects sufficient know-how to meet situational
demands For organizations concerned with reliability those developments
often consist of unexpected non-sequential interaction (p366)
An example of heedful interrelating occurs as a pilot lands herhis aircraft on the
deck of an aircraft carrier The pilot does not actually land She is recovered
A recovery is an interrelated set of activities among air traffic controllers
landing signal officers the control tower navigators deck hands the helmsman
driving the ship etc These activities can be interrelated more or less heedfully
depending on the care with which the different units contribute represent the
situation and subordinate their activities to the single purpose of successful
recovery (p 363)
You are to design a two-part study
Part I You are to design a measurement study which assesses heedful
interrelating (ie collective mind) with a quantitative measure in a replication
of an aircraft carrier flight deck or other situation of your choosing Describe
your research strategies including operationalization of the variable selection of
the sample subjects data collection data analysis and so on for the purpose of
developing a measure of heedful interrelating
Part II Using the measurement tool developed in Part I and any other tools as
needed describe how you would design a study which would compare heedful
interrelating across organizations Choose at least one macro-organizational
variable (eg technology environment) as your basis of comparison Here you
must describe how you would make your selection of organizations to be
compared your data collection procedure data analysis and so on
B15 Many organizations in the United States have installed cross-functional teams to
counteract the silo mentality of traditional bureaucratic structure Preliminary
evidence of the effectiveness of cross-functional teams however is mixed --
some organizations have claimed success and others have reported failures The
evidence moreover is predominantly anecdotal--written for trade magazines by
the organizations themselves Since there have been few rigorous empirical
field studies assessing the effectiveness of cross functional teams the National
Science Foundation has decided to fund research on the topic
Assume that you are submitting a research proposal to NSF for a grant to
research the effectiveness of cross-functional teams Describe in detail and
thoroughly explain the research design sampling plan data collection
procedures ethical issues and proposed data analysis for your research design
Be sure to discuss the internal and external validity of your research Which
validity threats are ruled out and which remain NSF also requires that you
provide a statement and defense of the explicit philosophy of science underlying
your research Describe your philosophy of science and discuss how your
research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but
you must also demonstrate to NSF that you are a competent researcher It is
absolutely vital to NSF that the principal researcher (you) is knowledgeable
about the proposed research methodologies Therefore be sure that you always
carefully describe and give technical explanations for each component of your
research design and explain all technical terms (eg Cronbach alpha KR-20
Likert scale)
B16 Assume that you are submitting a research proposal to the Department of
Commerce (DoC) for a grant to research the effectiveness of virtual work teams
A virtual work team is a leaderless collection of individuals who are
geographically separate from one another and share their expertise using
internet media such as a listserver or Lotus notes The DoC requires that the
researcher use both qualitative and quantitative methods to gather data Describe
in detail and thoroughly explain the research design sampling plan data
collection procedures ethical issues and proposed data analysis for your
research design Be sure to discuss the internal and external validity of your
research Which validity threats are ruled out and which remain The DoC also
requires that you provide a statement and defense of the explicit philosophy of
science underlying your research Describe your philosophy of science and
discuss how your research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but
you must also demonstrate to DoC that you are a competent researcher It is
absolutely vital to DoC that the principal investigator (you) is knowledgeable
about the proposed research methodologies Therefore be sure that you always
carefully describe and give technical explanations for each component of your
research

that improves upon the key validity (or validities)
5 MEASUREMENT
A) Measurement Terms
A1 There are four levels of measurement rigor in management research Discuss each
one What properties do measurements at each level have (ie how much
information do the numbers from each level of measurement convey) How can the
numbers be changed (transformed) and still retain the properties of their
measurement level Pick one construct from a favorite research domain and give an
example of an operationalization of that construct at each of the four levels of
measurement rigor (provide arguments about why you think those examples reflect
each level) Lastly treat each examplelevel as a dependent variable in some
statistical analysis Given an example of a statistical technique appropriate for
analyzing data at that level of measurement rigor
A2 Define (and discuss important features or issues concerning) the following
constructs measurement (Define any six terms)
1 Construct validity 6 Item analysis
2 Likert scaling 7 Semantic differential
3 Cronbachs alpha 8 True score
4 Unobtrusive (trace) measurement 9 Generalizability theory
5 Interval scale 10 Criterion-related validity
11 Sociometric choice measures
B) Operationalization
B1 a) You are conducting a study which requires you to measure Hong Kong real
estate agents self-assessment of performance Since there is no existing
measurement available you have to develop the instrument by yourself
Describe how you would develop the measurement assuming that you have no
idea of how many dimension the construct has
b) Suppose you have developed an instrument consists of 20 questions
measuring 4 dimensions (5 items per dimension) from (a) You collected data
from another 300 real estate agents to validate your instrument Explain how
TH
you would use structural equations model (SEM) to examine the reliability and
validity of the instrument What are other concerns about reliability and validity
that are not addressed by this approach
B2 The research and business world have been fascinated with the concept of
organizational culture However operationalizing this construct has been a
difficult task Discuss the ways in which the construct has been operationalized
(eg technique static v dynamic sample selection generalizability) Critically
analyze each of these methodologies Then choose a methodology you would
use to examine organizational culture and defend your choice Describe how
you would study culture and what more would be known about culture as a
result of your study
B3 Suppose you are setting out to develop a new measure of a construct You want
this measure to be used in survey research and you want to establish its validity
and reliability Your goal is to have at the end of the process a measure that is
defensible and likely to be widely accepted by other researchers studying that
construct What steps would you take to conduct such a program of research
For each step explain the purpose of that step explain why that step is
important explain what methods and statistical procedures you would employ at
each step and explain what evidence you would hope to gather at each step
B4 Assume you are interested in constructing a new measure of (fill in with a
relevant variable from your field) Detail the major concerns that need to be
addressed and the steps that need to be taken in working toward validating this
new measure
B5 Assume that you recently read an article on workplace violence which you
found very interesting The authors argued that one of the predictors of
workplace violence was a construct called propensity to be violent and used a
one-item measure as follows How likely are you to become violent when
provoked You had serious doubts about the authors measure and decided to
develop your own
(a) How would you go about developing items to measure propensity to be
violent
(b) How would you determine whether the instrument was reliable
How would you determine whether the instrument was valid
B6 A concern in organizations is retirement of baby boomers within the next 5 -
10 years This concern is focused on the loss of older employees with skills
critical to the core business functions of organizations In order to continue to
have employees with those critical skills it seems necessary to retrain some
older workers However past practice in most organizations has been not to
retrain older workers for a variety of reasons mostly financial A researcher
working for the Human Resources Department of a large corporation - 13500
employees in 12 different plant locations - hypothesizes that the major reason
for not retraining older workers is ingrained in the culture of the corporation
IC
The researcher feels that older workers are not as highly valued as younger
workers in terms of their potential usefulness after retraining The researcher
searched the literature but found nothing in the existing literature to measure
the cultural value construct What should the researcher do to establish a reliable
and valid self-administered paper and pencil measure of this construct namely
the value of retraining older workers
a Please describe and explain the steps in temporal order that the researcher
must follow to develop a measure
b How would you evaluate the measure based on the technical requirements of
reliable and valid measurement as well as any practical issues in using the
measure considering the size of the employee population
B7 Assume that you are going to conduct empirical research to assess the role that
the complexity of an organizations manufacturing technology plays in
determining the level of centrality of decision making in the organization
Describe and justify the steps you might follow to develop an operationalization
of the concept of technological complexity What standards would you use to
determine if your operationalization is valid
B8 Organizational researchers have several strategies available to them for
gathering information (eg self-report measures archival measures direct
observation and trace measures) Assume that you are going to conduct
empirical research to assess the role that the structure of the organization plays
in determining the level of organizational effectiveness Briefly review the
strengths and weaknesses of the basic strategies (that is self-report measures
archival measures direct observation and trace measures) for measuring
organizational effectiveness Next describe and justify the steps you would
take to develop an operationalization of the concept of organizational
effectiveness What standards and procedures would you use to determine if
your operationalization is valid
B9 One of the most important topics of recent research has been stress in the work
place One of the most important problems with understanding this literature is
the varying definitions and measurement of this construct Suppose you had
decided to investigate the relationship between stress at the work place and dual
career family happiness
a Since there are multiple ways to measure stress in the work place describe
two ways to do this Hint - avoid using two self-report measures
b Describe how you would decide on the best single measure In doing so
describe the steps you would take in evaluating your measure Be sure to define
your meaning of validity and reliability It is important that your measure have
all the necessary psychometric characteristics so that other scientist can trust the
results of your research
c Be certain that you answer the question Validity for what
d In order to understand the results of your study you need to compare your
measure of stress at work with other measures of this construct How would you
do that
B10 Assume that you have been hired by a national survey research company
Shash Inc to write items that will be used in a national survey of attitudes
toward capital punishment There are a number of criteria that can be used to
guide your item writing What are they Briefly describe five (5) such criteria
B11 Assume that you are going to conduct empirical research to determine the
impact of interpersonal trust on organizational decision making Describe and
justify the steps you might follow to develop an operationalization of the
interpersonal trust concept
B12 Assume that you are going to conduct empirical field research to assess the role
that employee empowerment plays in determining the level of organizational
commitment of employees Describe and justifyexplain the steps you would
follow to develop a valid and reliable operationalization of the concept of
employee empowerment
Explain the procedures and standards you would use to determine if your
operationalization is valid and reliable
How would you assess the construct validity of such a measure
Discuss issues concerning the level of observation of your measure and level of
analysis of the data
B13 Assume you are interested in developing a new scale to measure construct X
Further assume that you have used previous literature and your own conceptual
development to delineate 2 dimensions of X specifically XF1 and XF2
Describe the steps you would go through in developing testing and evaluating
this new scale With regard to testing and evaluating be sure to consider the
role of factor analysis (both exploratory and confirmatory) and item analysis
Also you will want to make sure that your new multidimensional scale shows
evidence of validity (several kinds) and reliability so be sure to examine these
issues and explain how specific information gathered from the above testing
contributes to these concerns
C) Reliability
4) What is reliability and why is it so important What are the different ways reliability can be
assessed and when is each appropriate
15) What does coefficient alpha assess What are the ways coefficient alpha can be increased
C1 Describe and discuss the concept of reliability and all of its various forms
including their assessment When is each form appropriate and what information
is provided by each index
C2 In establishing congruence between multiple measurements we often compute
indices of reliability andor indices of agreement These two types of indices
address very different questions Your task is to 1) Define reliability and
agreement 2) Explain when each is useful using examples in which one but not
the other is appropriate and 3) Briefly describe two reliability indices and two
agreement indices
C3 Explain reliability in terms of the classical test theory What are the
consequences of unreliable measures in hypothesis testing What are the factors
that may affect the reliability of a multi-item scale
IC
C4 Generalizability theory is used within IO psychology more often today
However most researchers continue to use Classical Test Theory
conceptualizations of error to determine reliability What are the implications of
using classical test theory versus generalizability theory to assess reliability
C5 In establishing congruence between measurements we often compute indices of
reliability andor agreement Define reliability and agreement Explain the
differences in reliability and agreement and describe under what conditions
assessing reliability is more appropriate and under what conditions assessing
agreement is more appropriate
C6 Define measurement reliability in terms of a specific measurement theory (eg
true test score theory domain sampling theory generalizability theory IRT)
Discuss the different approaches for estimating reliability and the contexts in
which each might be appropriate Use examples throughout
C7 What are the consequences of unreliability in a measure
C8 What are some of the conditions that might keep the internal consistency (eg
alpha) of a given measure low Is a low alpha always a sign of a problematic
measure
C9 Define reliability Name some methods of calculating reliability How well do
these methods map up with the definition of reliability What is the impact of the
number of test items and sample size on Chronbachs alpha and why would this
effect occur or not occur (Note Do NOT discuss inter-rater reliability)
C10 Schmidt and Hunter (1996) described several types of measures typically used in
organizational research and identified the type(s) of measurement error affecting
each of them in various situations For each measure below indicate the types of
error and sources of error that are most likely to affect it Then indicate what
could be done to reduce errors of measurement andor what can be done to
control for errors statistically
a Supervisor ratings of subordinates job performance
b Self-ratings of ones own job performance
c Self-reports of ones own job-related attitudes
d Sales figures for a salesperson (or production quantity for a production
worker)
d Aptitude tests taken as part of the hiring process
C11 Suppose you had conducted research on the relationship between organizational
commitment and rigidity of organizational structure in 200 firms Your measure
of rigidity was based on number of organizational authority levels and the degree
to which written organizational rules existed and defined role behaviors for
employees Thus an organization with a large number of organizational levels
and specific written policies defining appropriate role behaviors for employees
would score high on rigidity of organizational structure After analyzing your
data you find that there is a statistically significant negative correlation between
commitment and rigidity which is consistent with your hypothesis However the
reliabilities for your two measures are
(1) commitment = 23 (2) rigidity = 83
How should you interpret your results What could you do to fix this situation
Describe the specific steps (in order) you would follow to develop a more
reliable measure of commitment
C12 (a) Define the concept of reliability (of measures) in a clear concise and
accurate manner (b) Provide a formula that expresses the reliability of a measure
in terms of two components of variance ie total variance and the error
variance
D) Multi-level Assessment
D1 One of the major challenges for group-level research is the issue of aggregation of
individual data to the group level
(a) Under what conditions (eg types of data number of raters) should the various
interrater agreement and reliability methods be used (Rwg Kappa and Weighted
Kappa percent agreement average pairwise correlation ANOVA methods
(interclass correlation coefficient WABA)) What are the advantages and
disadvantages of each of the methods
(b) Explain the controversy between Frank Schmidt Larry James and others
regarding the differences between interrater agreement and interrater reliability
Who is right Do the differences matter in research practice
Defend your answers
(c) Review two articles from the organizational behavior literature that have had to
deal with aggregation issues Critique the methods the authors used to make
aggregation decisions
(d) Provide some advice to researchers regarding what they should do if interrater
agreement and reliability indices indicate that it is not legitimate to aggregate their
data
(e) Provide some ideas for avoiding the need to aggregate in group-level research
through creative research methods and measurement strategies
D2 Cross-levelmulti-level research is becoming more evident in the organizational
research literature This type of research raises many issues and presents many
challenges in terms of designing the research measuring variables and collecting
and analyzing the data Assume that you are interested in aggregating data (eg
from the individual to the group or from the firm to the industry) for one or more
variables What are the major issues you will need to deal with
D3 A researcher wants to measure organizational climate for continuous learning
Organizational climate is operationalized as a shared consensual aspect of the
organization -- the shared perception among employees that the organization values
and supports continuous learning Describe how you would measure organizational
climate in this case Specify (a) the level (ie individual group organization) at
which the construct exists (b) the level at which you would measure the construct
and (c) the procedures that you would use to establish that measurement is aligned
with theory (ie the construct validity of the measure)
E) General (Measurement)
E1 Studies in organizational behavior research often rely on single-item measures of
key constructs The use of single-item measures has long been criticized based
on the premise that single-item measures are unreliable However Wanous
(Wanous amp Hudy 2001 Wanous amp Reichers 1996 Wanous Reichers amp Hudy
1997) has recently argued that single-item measures can exhibit adequate
reliability Wanous based this conclusion on a procedure for estimating the
reliability of single-item measures using the classic formula for correction for
attenuation Subsequent studies have yielded mixed results regarding the
conclusions of Wanous (eg Loo amp Kells 1998 Nagy 2002) and the veracity
of the perspective advocated by Wanous remains in question Summarize and
assess the arguments for and against the use of single-item measures and
evaluate the procedure and evidence offered by Wanous regarding the reliability
of single-item measures Based on your assessment and evaluation develop
recommendations regarding the use of single-item measures in organizational
behavior research

E2 Ipsative measures have become prevalent in organizational behavior research
Ipsative measures ask respondents to answer questions relative to one another
such that the scores for all questions sum to the same constant for all respondents
Examples of ipsative measures include rankings Q-sorts and the allocation of a
fixed number of points (eg 100) across a set of response options Ipsative
measures may be contrasted with absolute measures which ask respondents to
answer questions independently from one another Absolute measures are
exemplified by rating scales using an interval or ratio numeric response format
The relative merits of ipsative and absolute measures have been debated for
decades (eg Cornwell amp Dunlap 1994 Hicks 1970 Johnson Wood amp
Blinkhorn 1988 Saville amp Wilson 1991 1992) yet the fundamental issues
underlying this debate have not been adequately addressed in organizational
behavior research For example measures of organizational culture and values
are often ipsative and some researchers advocate these measures over absolute
measures (eg Meglino amp Ravlin 1987 OReilly Chatman amp Caldwell 1991
Ravlin amp Meglino 1987 see also Rokeach amp Ball-Rokeach 1989) Review the
relative merits of absolute and ipsative measures Based on your review which
form of measurement is most appropriate and why Do your conclusions depend
on the construct being measured If so what types of constructs are best suited to
ipsative measures and what types are best suited to absolute measures Next
apply your conclusions to the measurement of culture and values in
organizations What specific arguments have been advanced in favor of ipsative
measures of culture and values How sound are these arguments Should ipsative
measures be used in the study of organizational culture and values If not how
can absolute measures of culture and values be developed that address the
concerns voiced by advocates of ipsative measures Provide a specific example
of the type of measure you would propose

E3 In organizational research measures often consist of items that represent different
facets of a concept Although such measures are prevalent and in some cases are
advocated (eg Law et al 1998 1999) they can present a variety of conceptual
and methodological problems Describe the specific problems associated with
measures that use items representing different facets of a concept Compare these
problems with the purported advantages of such measures Conclude by

E5 Suppose Roberta Von Eisenbrick is a researcher interested in the consequences of
AFFECTIVE CONFLICT (AC) in decision-making teams She gets access to a
variety of outcomes assessment committees at each of 87 different schools in
the Dallas Independent School District and gains permission to tape-record two
of their meetings (one in February and one in March) Such committees have
been formed to develop quantitative ways to track pursuit of school goals and
provide accountability to local and state governments These are often divisive
teams with heated meetings because what gets assessed is what usually gets
rewarded After both of these meetings the committee members each
fill out a short questionnaire that contains 20 Likert-type items measuring how
much AC occurred (eg People in our group often get angry with each other)
The individual scores are summed across items then averaged across team
members to come up with a group-level AC score for each of the 87 2
meetings The same procedures are followed for a 5-item measure of Group

(a) Please define both of these terms (b) Sketch a conceptual model to show how
each relates to main effects (c) Using variables of your choice please write
hypotheses to reflect both (d) Explain how each is tested analytically
D2 Discuss moderators and mediators Provide an example of how (1) a moderating
variable influences the relationship between the independent and dependent
variable and how (2) a mediating variable influences the relationship between
the independent and dependent variable Describe how you would test for both
moderation and mediation using regression
D3 Many theories in organizational research predict that the effects of one variable
on another are moderated by a third variable Such moderator effects are
typically tested by entering the product of two variables as a predictor after
controlling for the two variables that constitute the product Several researchers
have pointed out that this product is often highly correlated with the squares of
the two constituent variables and have suggested that moderating effects may be
tested after controlling not only for the two constituent variables but also their
squares (eg Cortina 1993 Ganzach 1998 Lubinski amp Humphreys 1990
MacCallum amp Mar 1995) Discuss the strengths and weaknesses of this
approach as compared to methods that use only the product term and its
constituent variables Conclude with recommendations as to when and under
what conditions organizational researchers should test moderator effects with the
squares of the constituent variables in the equation

D4 Assume you are interested in studying relationships amongst three variables X
Y and Z Your first hypothesis posits Z as a mediator of the relationship between
X and Y Your second hypothesis posits Z as a moderator of the relationship
between X and Y Draw the figures depicting each of these hypothesized
relationships and describe (make sure to write regression equations) how you
would test each of these hypotheses
D5 The amount of time and effort that the average person pours into his or her job
has risen steadily over the last two decades such that the average person now is
working one more week per year than the average person in the mid 1970s This
steady increase has fueled research interest in the construct of Job Burnout (JB)
which is an emotional and physical exhaustion associated with ones work
Organizational Stress (OS) the perception of greater demands than available
resources in ones work environment is thought to be one of the chief
antecedents of JB However time spent under OS is thought to make its affects
on JB accumulate or worsen Work Role Withdrawal (WRW) the avoidance of
responsibilities or the deliberate reduction of inputs to ones job is believed to be
the chief consequence of JB

directed graph (circle amp arrow diagram)
b Conceptually what is a mediator Define the term and identify the mediator in
your hypotheses in (a) What elements or steps in a study design (not statistics)

subdomains of management Further demonstrate your understanding of
moderator variables by picking which variable in (a) is the moderator Show the
moderating relationship in an X-Y (or multi-layered) chart Again what elements
or steps in a study design (not statistics) would be helpful for detecting the
moderating effect implied above

recommendations You conduct a well-designed controlled study (details are unimportant) and discover students who use the new book perform 10 better on a standardized subject
matter exam than those using the old book (p = 027) Both books are readily availabe their prices are almost identical and both are equally acceptable to the instructors What is your recommendation to the chair
F1 Attached is the beginning of an article Your task is to write the results section by
1 making up and reporting plausible descriptive statistics that will help the
reader understand the results of the statistical tests you report and the nature of your
sample (Hint this can be presented in the form of a table)
2 describing and defending your choice of appropriate statistical tests of the
hypotheses and the steps that you would go through in carrying out these tests
3 making up and reporting results of these tests that are consistent with your
descriptive statistics and with any information in the rest of the article about the
results found (Hint this can be presented in the form of a table)
4 describing how well these results provide support for the hypotheses You
may want to note any relevant threats to validity here
Be sure to state any assumptions you make
F2 Assume that the Personnel Manager of a local firm Ms B dFlandres hired you to
analyze some data that her assistants had collected over the past several years The
data consist of (a) job performance ratings that were made in June of 1990 and (b)
scores on 25 predictor variables (eg measures of education job experience job
tenure job aptitude personality) that were measured when the individuals were hired
(between April 1987 and May 1988) She had data from only the 110 subjects (60
males and 50 females) who were hired during the period and were still employed by
the firm One objective of your analysis (analyses) is to determine how well the
performance criterion can be predicted by the predictors What strategy would you
use in analyzing the data Describeexplain (b) Is sample size an issue for your
analyses Explain If it is what will you do to deal with problems stemming from
sample size Assume that no additional data can be collected at this time (c) Some
preliminary analyses that you do reveal that five of the predictor variables correlate
(zero-order basis) about 75 with one another Will this influence the analyses that
you use Will it influence the validity of conclusions derived from your proposed
analyses (d) Ms dFlandres is interested in knowing if the predictor variables are
equally effective in predicting the job success of males and females What analysis
or analyses would you do to deal with this issue
F3 Assume that you have been provided with data on 12 conceptually distinct variables
that are moderately correlated with one another at the empirical level The data are
from students in four different college majors ie astronomy (A) biology (B)
criminology (C) and demography (D) The 12 measured variables fall into the
general categories of mental health (tension emotional withdrawal hallucinations
guilt feelings blunted affect and suspiciousness) and job satisfaction (work itself
supervision co-workers pay promotion prospects and working conditions) Your
task is to determine if the individuals in the four college majors differ from one
another on the 12 measured variables
(a) What statistical technique(s) would you use to test for group differences
Explain Be specific about the procedures(s) that you would use
(b) What statistical estimate would you use to estimate the extent to which the
groups differ from one another Be specific
F4 The following statistical table published in a recent issue of Work amp Occupations
was taken from an article discussing variables influencing resistance and citizenship
behaviors in the workplace Resistance behaviors include playing dumb withholding
effort work avoidance subverting particular managers and sabotage Citizenship
behaviors include cooperation engaging in peer training use of insider knowledge to
facilitate production commitment to organizational goals giving extra effort freely
Both measures are global constructs aggregated to the interval level and
standardized
The table reports the results of a series of ordinary least squares regression equations
with standardized coefficients Explain the meaning of the statistics presented What
do these statistics tell us generally about the relationship between resistance
behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows
Anomie Index -standardized interval level measure tapping multiple dimensions
The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)
F5 Researchers collected data from a sample of 350 companies on the following
variables
size (measured as number of employees)
Business Strategy (a nominal variable with 2 response options low-cost provider or
differentiator)
HR Strategy (a nominal variable with 2 response categories High commitment or
low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

O4 Describe the differences between exploratory factor analysis (EFA) and
confirmatory factor analysis (CFA) When would you use one verses another
Are there ways to use EFA in a confirmatory way Can you use CFA in an
exploratory way Also describe the difference in principal components analysis
(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression

P) Structural Equation Models
P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is

P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)
Please comment on these restrictions versus access argument Which side do you
take
What are the strengths of SEM Give some examples
What are the weaknesses of SEM Give some examples

popular some people complain that the frequent use of e-mail leads to
miscommunication because they receive communications in e-mail that should
be accomplished through face-to-face or telephone conversations where there is
an opportunity for interaction You are interested in looking at this
phenomenon You are most interested in describing how e-mail is used for both
formal and informal communication and in examining the effect of the e-mail
use on organizational communication effectiveness Design empirical research
to address those issues
Describe your study in detail thoroughly explaining the research design
sampling plan data collection procedures ethical issues and proposed data
analysis for your research design Be sure to discuss the internal and external
validity of your research Which validity threats are ruled out and which
remain
REMEMBER Be thorough Your research design should demonstrate that you
are a competent researcher who is knowledgeable about the proposed research
methodology or methodologies Therefore be sure that you carefully describe
and give technical explanations for each component of your research
B5 Choose a specific situation involving employee selection eg artists for an
advertising agency (a) What strategy would you use in selecting the selection
measures (b) How would you combine the measures eg which measures
would you combine in a compensatory manner and which is a noncompensatory
manner (c) How would you assume test fairness defining various measures of
the term (d) How would you make final selections (e) How would you
validate your procedure (f) What considerations would enter in if your
company were too small to provide validation data (g) What difference would
it make if you were developing a procedure for deciding whether trainees
should be promoted as opposed to making new hires Please note--emphasize
but do not limit yourself to statistical issues
B6 There is evidence in the marketing literature of a non-monotonic relationship
between the expectations that customers have for retail service and their
eventual level of satisfaction with that service That is as a customers
expectations for service increase so does their eventual service satisfaction --
up to a point After that point the greater the expectations the lower the
eventual satisfaction Develop a hypothesis that includes a moderator variable
that might account for this evidence Give some reasonable rationale for it State
your hypothesis verbally as an equation as a directed graph (circle amp arrow
diagram) and as an X-Y function chart Discuss how it would or would not be
possible or useful to test your hypothesis via a laboratory experiment In your
discussion cover how and why a researcher could (not) manipulate the
independent constructs involved (mode X) whether or not random assignment
to conditions (mode R) is possible (including how may conditions would be
necessary) which alternative constructs could or could not be controlled (mode
K) and which constructs should be measured (mode Y)
B7 Assume you are the chairperson of a committee that must evaluate
undergraduate programs at your university Your task as chairperson is to
devise an approach (a design a research strategy a set of measures) that will
allow you to evaluate undergraduate programs Make sure that your approach
can be used in the future and at other comparable universities When developing
your plan be sure to address at least the following issues
a the type of design you would select Compare and contrast the selected design
with another possible design
b the type of research strategy you would select Compare and contrast with
another possible strategies
c discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
B8 Assume you are an organizational research design expert assigned to the
Strategic Planning Department of a large multi-national manufacturing firm
The Department has developed a new PC-based software package called
STRATPACK The software (and a one-week training course to learn how to
use it) is intended to improve the long-range planning ability of middle and
upper-level managers
Your job as research design expert is to devise research (a design a research
strategy a set of measures) that will allow you to evaluate the effectiveness of
the STRATPACK program Describe a research design for evaluating the
program Make sure that your research approach can be used in the future and at
all sites in the company When developing your plan be sure to address at least
the following issues
a discuss how your design and approach deals with the major forms of validity

least internal external and construct validity
B9 Assume you are a consultant hired to evaluate the effectiveness of an industrial
safety program undertaken by a large manufacturing organization The safety
program is a behavioral one that provides rewards such as monetary bonuses or
extra paid vacation days for safety behaviors in terms of accident-free days
weeks etc Your task is to devise an approach (a research strategy a design a
set of measures and a general analysis strategy) that will allow you to evaluate
the safety program Because of the potential for the influence of many
extraneous variables on any safety program it is difficult to design research a
single cross-sectional study than can evaluate the impact of a single safety
program How would you design a study to evaluate the impact of the safety
program When developing your plan be sure to address at least the following
issues
a the type of research strategy you would select Compare and contrast with
another possible strategies

with another possible design
c discuss how your design and approach deals with the major forms of validity
Be sure to examine at least internal external and construct validity
B10 One of the most important areas of research is forecasting of human resources
needs based on strategic positions of organizations For example NY State must
carefully forecast its human resources needs as it proceeds with significant lay-
offs of state employees Future human resources needs are generally evaluated
by either statistical ie regression or simulation or clinical judgment i e
supervisors judgments methods
a Design a single study that addresses the empirical question of whether
statistical or judgmental methods are better for forecasting human resources
needs You may discuss a program of research but please be quite specific in
your description of the first study
b What are the critical methodological issues in doing this kind of research
c What are the critical applied (or practical) issues in doing this research
d Are the issues in b and c related
B11 In the past decade computinginformation technology has changed many
aspects of organizational life For example the technology can make increased
decentralization possible by improving communication between central offices
and field offices Computer networks and word processors can enhance group
empowerment by making it possible for team members to create and edit
written group products quickly even if the individuals are at different locations
Some have argued that computinginformation technology will foster the
paperless productive office nevertheless others argue that the technology only
increases paper and reduces office productivity You are applying to the
National Science Foundation for a grant to conduct research that examines the
impact of computing information technology on organizational decision
processes The NSF application procedure imposes five basic requirements that
your research design must fulfill in order to receive funding Note A very
significant factor affecting NSF grant decisions is a clear demonstration that the
researcher is knowledgeable about the research methodology used Write your
response to each of the following five grant requirements Be sure not only to
respond to the requirement but also to demonstrate your research
competence
1You must design a study that uses two different methods
(interviewobservation survey experiment or quasi-experiment) Describe your
two methods in detail and provide a rationale for the key elements (eg
sampling data collection proposed analysis) of your methods Be sure to
discuss and evaluate the internal and external validity of both methods
2 As part of your research design you must select a conceptual (latent) variable
central to your proposal (use centralization of decision making as your
variable) and describe how you will develop your own measure (You may not
simply use off the shelf instruments)
3 You must describe how you will test for the reliability of the measure
(centralization of decision making) you developed in step 2 The NSF insists
that you describe how you will evaluate both the temporal stability and the
internal consistency of your measure Be sure to discuss what temporal stability
and internal reliability mean and how they are related
4You must describe how you will assess the validity of the measure
(centralization of decision making) you developed in step 2
5 NSF requires a brief statement and defense of the philosophy of science
underlying your research Discuss your position and show how your research
design is consistent with your philosophy
B12 Many organizations in the United States economy have installed some form of
Empowered Teams as an alternative or supplement to traditional bureaucratic
structure Preliminary evidence of the effectiveness of empowered teams
however is mixed--some organizations have claimed success and others have
reported failures The evidence however is predominantly anecdotal--written
for trade magazines by the organizations themselves There are few rigorous
empirical studies assessing the effectiveness of empowered or self-managed
teams You are applying to the United States Department of Labor (USDOL) for
a grant to conduct research that examines the effectiveness of empowered
teams The application procedure of the USDOL imposes three requirements
that your research design must fulfill in order to receive funding Write your
response to each of the three grant requirements The importance of each section
is implied by the evaluation points allocated by the USDOL to each of the three
requirements given in parentheses
1 (50 points) Your study design for assessing Empowered Team effectiveness
must use two different methods (interview observation archival analysis
survey simulation experiment or quasi-experiment) Describe in detail and
thoroughly explain the sampling plan instrumentation data collection
procedures and proposed data analyses for both methods Be sure to discuss the
internal and external validity of both methods and how the two methods
complement one another
2 (30 points) As part of your research design you must select one conceptual
(latent) variable central to your proposal and describe how you will develop
your own operationalization of the measure (You may not simply use off the
shelf instruments) Use the concept of group morale to demonstrate your
operationalization methodology Be sure to explain very explicitly to the
USDOL how you will assess the validity and reliability of the group morale
measure you are developing
3 (20 points) The USDOL traditionally has funded research conducted only
within the general paradigm of logical positivism but now is more open to other
research paradigms as well Your grant proposal must provide a statement and
defense of the explicit philosophy of science underlying your research Describe
your philosophy of science and show how your research design is consistent
with your philosophy
REMEMBER Be thorough You not only must design effective research but
you also must demonstrate to the USDOL that you are a competent researcher
It is absolutely vital to the USDOL that the principal researcher is
knowledgeable about the proposed research methodologies Therefore be sure
that you always carefully describe and give technical explanations for each
component of your research design and explain all technical terms (eg
Cronbach alpha KR-20 Likert scale)
B13 Assume that you are working as part of a research team that is responding to a
RFP (Request for Proposals) from a funding agency for research on work
socialization and newcomer adjustment The RFP calls for rigorous field
research that tests the effectiveness of theory-based interventions aimed at
facilitating the adjustment of new organizational members to complex andor
stressful work conditions The major goal of your teams research is to test the
effectiveness of a self-regulation intervention which trains newcomers to
identify and use relevant social information and cues to regulate work behavior
Your group hypothesizes that self-regulation training will be more effective
than other common treatments or interventions (eg realistic job previews
institutionalized socialization tactics)
You have been included in the team because of your methodological expertise
Your role is to design a rigorous field experiment or quasi-experiment to test he
effectiveness of the self-regulation training program REMEMBER THE
MAJOR CRITERION FOR FUNDING IS THE RIGOR OF THE RESEARCH
DESIGN Design a field study to include in the grant proposal Your proposal
should contain the following two sections
1 Study Design Construct and describe in detail an experimental or quasi-
experimental design to test the effectiveness of your intervention Describe in
detail the experimental groups (including how they will be constructed) the
research setting the sampling plan for study participants the treatment
manipulation and the data collection procedures Also indicate any control or
nuisance variables that may be measured
After describing the procedures write a justification of the design What threats
to validity does it rule out or limit and what threats to validity remain
II Measurement Describe the steps you would take to achieve valid and
reliable measure of the latent (conceptual) variable worker adjustment Your
team feels that as part of the proposal you must develop an original
operationalization of adjustment (thus you cannot simply use existing off the
shelf measures) Indicate in adequate detail how you would operationalize the
measure and indicate how you would demonstrate reliability and validity
B14 In describing their notion of the collective mind Karl E Weick and Karlene H
Roberts note Our focus is at once on individuals and the collective since only
individuals can contribute to a collective mind but a collective mind is distinct
from an individual because it inheres in the pattern of interrelated activities
among many people (p 360) Collective mind is not indexed by within-group
similarity of attitudes ideas or activities A collective mind is one in which
many people or many groups integrate their different attitudes ideas and
activities heedfully As Weick and Roberts note People act heedfully when
they act more or less carefully critically consistently purposefully attentively
studiously vigilantly conscientiously pertinaciously (p 361)
The idea of the collective mind as heedful interrelating is developed in the
following excerpt When people make efforts to interrelate these efforts can
range from heedful to heedless The more heed reflected in a pattern of
interrelations the more developed the collective mind and the greater the
capability to comprehend unexpected events that evolve rapidly in unexpected
ways When we say that a collective mind comprehends unexpected events we
mean that heedful interrelating connects sufficient know-how to meet situational
demands For organizations concerned with reliability those developments
often consist of unexpected non-sequential interaction (p366)
An example of heedful interrelating occurs as a pilot lands herhis aircraft on the
deck of an aircraft carrier The pilot does not actually land She is recovered
A recovery is an interrelated set of activities among air traffic controllers
landing signal officers the control tower navigators deck hands the helmsman
driving the ship etc These activities can be interrelated more or less heedfully
depending on the care with which the different units contribute represent the
situation and subordinate their activities to the single purpose of successful
recovery (p 363)
You are to design a two-part study
Part I You are to design a measurement study which assesses heedful
interrelating (ie collective mind) with a quantitative measure in a replication
of an aircraft carrier flight deck or other situation of your choosing Describe
your research strategies including operationalization of the variable selection of
the sample subjects data collection data analysis and so on for the purpose of
developing a measure of heedful interrelating
Part II Using the measurement tool developed in Part I and any other tools as
needed describe how you would design a study which would compare heedful
interrelating across organizations Choose at least one macro-organizational
variable (eg technology environment) as your basis of comparison Here you
must describe how you would make your selection of organizations to be
compared your data collection procedure data analysis and so on
B15 Many organizations in the United States have installed cross-functional teams to
counteract the silo mentality of traditional bureaucratic structure Preliminary
evidence of the effectiveness of cross-functional teams however is mixed --
some organizations have claimed success and others have reported failures The
evidence moreover is predominantly anecdotal--written for trade magazines by
the organizations themselves Since there have been few rigorous empirical
field studies assessing the effectiveness of cross functional teams the National
Science Foundation has decided to fund research on the topic
Assume that you are submitting a research proposal to NSF for a grant to
research the effectiveness of cross-functional teams Describe in detail and
thoroughly explain the research design sampling plan data collection
procedures ethical issues and proposed data analysis for your research design
Be sure to discuss the internal and external validity of your research Which
validity threats are ruled out and which remain NSF also requires that you
provide a statement and defense of the explicit philosophy of science underlying
your research Describe your philosophy of science and discuss how your
research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but
you must also demonstrate to NSF that you are a competent researcher It is
absolutely vital to NSF that the principal researcher (you) is knowledgeable
about the proposed research methodologies Therefore be sure that you always
carefully describe and give technical explanations for each component of your
research design and explain all technical terms (eg Cronbach alpha KR-20
Likert scale)
B16 Assume that you are submitting a research proposal to the Department of
Commerce (DoC) for a grant to research the effectiveness of virtual work teams
A virtual work team is a leaderless collection of individuals who are
geographically separate from one another and share their expertise using
internet media such as a listserver or Lotus notes The DoC requires that the
researcher use both qualitative and quantitative methods to gather data Describe
in detail and thoroughly explain the research design sampling plan data
collection procedures ethical issues and proposed data analysis for your
research design Be sure to discuss the internal and external validity of your
research Which validity threats are ruled out and which remain The DoC also
requires that you provide a statement and defense of the explicit philosophy of
science underlying your research Describe your philosophy of science and
discuss how your research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but
you must also demonstrate to DoC that you are a competent researcher It is
absolutely vital to DoC that the principal investigator (you) is knowledgeable
about the proposed research methodologies Therefore be sure that you always
carefully describe and give technical explanations for each component of your
research

that improves upon the key validity (or validities)
5 MEASUREMENT
A) Measurement Terms
A1 There are four levels of measurement rigor in management research Discuss each
one What properties do measurements at each level have (ie how much
information do the numbers from each level of measurement convey) How can the
numbers be changed (transformed) and still retain the properties of their
measurement level Pick one construct from a favorite research domain and give an
example of an operationalization of that construct at each of the four levels of
measurement rigor (provide arguments about why you think those examples reflect
each level) Lastly treat each examplelevel as a dependent variable in some
statistical analysis Given an example of a statistical technique appropriate for
analyzing data at that level of measurement rigor
A2 Define (and discuss important features or issues concerning) the following
constructs measurement (Define any six terms)
1 Construct validity 6 Item analysis
2 Likert scaling 7 Semantic differential
3 Cronbachs alpha 8 True score
4 Unobtrusive (trace) measurement 9 Generalizability theory
5 Interval scale 10 Criterion-related validity
11 Sociometric choice measures
B) Operationalization
B1 a) You are conducting a study which requires you to measure Hong Kong real
estate agents self-assessment of performance Since there is no existing
measurement available you have to develop the instrument by yourself
Describe how you would develop the measurement assuming that you have no
idea of how many dimension the construct has
b) Suppose you have developed an instrument consists of 20 questions
measuring 4 dimensions (5 items per dimension) from (a) You collected data
from another 300 real estate agents to validate your instrument Explain how
TH
you would use structural equations model (SEM) to examine the reliability and
validity of the instrument What are other concerns about reliability and validity
that are not addressed by this approach
B2 The research and business world have been fascinated with the concept of
organizational culture However operationalizing this construct has been a
difficult task Discuss the ways in which the construct has been operationalized
(eg technique static v dynamic sample selection generalizability) Critically
analyze each of these methodologies Then choose a methodology you would
use to examine organizational culture and defend your choice Describe how
you would study culture and what more would be known about culture as a
result of your study
B3 Suppose you are setting out to develop a new measure of a construct You want
this measure to be used in survey research and you want to establish its validity
and reliability Your goal is to have at the end of the process a measure that is
defensible and likely to be widely accepted by other researchers studying that
construct What steps would you take to conduct such a program of research
For each step explain the purpose of that step explain why that step is
important explain what methods and statistical procedures you would employ at
each step and explain what evidence you would hope to gather at each step
B4 Assume you are interested in constructing a new measure of (fill in with a
relevant variable from your field) Detail the major concerns that need to be
addressed and the steps that need to be taken in working toward validating this
new measure
B5 Assume that you recently read an article on workplace violence which you
found very interesting The authors argued that one of the predictors of
workplace violence was a construct called propensity to be violent and used a
one-item measure as follows How likely are you to become violent when
provoked You had serious doubts about the authors measure and decided to
develop your own
(a) How would you go about developing items to measure propensity to be
violent
(b) How would you determine whether the instrument was reliable
How would you determine whether the instrument was valid
B6 A concern in organizations is retirement of baby boomers within the next 5 -
10 years This concern is focused on the loss of older employees with skills
critical to the core business functions of organizations In order to continue to
have employees with those critical skills it seems necessary to retrain some
older workers However past practice in most organizations has been not to
retrain older workers for a variety of reasons mostly financial A researcher
working for the Human Resources Department of a large corporation - 13500
employees in 12 different plant locations - hypothesizes that the major reason
for not retraining older workers is ingrained in the culture of the corporation
IC
The researcher feels that older workers are not as highly valued as younger
workers in terms of their potential usefulness after retraining The researcher
searched the literature but found nothing in the existing literature to measure
the cultural value construct What should the researcher do to establish a reliable
and valid self-administered paper and pencil measure of this construct namely
the value of retraining older workers
a Please describe and explain the steps in temporal order that the researcher
must follow to develop a measure
b How would you evaluate the measure based on the technical requirements of
reliable and valid measurement as well as any practical issues in using the
measure considering the size of the employee population
B7 Assume that you are going to conduct empirical research to assess the role that
the complexity of an organizations manufacturing technology plays in
determining the level of centrality of decision making in the organization
Describe and justify the steps you might follow to develop an operationalization
of the concept of technological complexity What standards would you use to
determine if your operationalization is valid
B8 Organizational researchers have several strategies available to them for
gathering information (eg self-report measures archival measures direct
observation and trace measures) Assume that you are going to conduct
empirical research to assess the role that the structure of the organization plays
in determining the level of organizational effectiveness Briefly review the
strengths and weaknesses of the basic strategies (that is self-report measures
archival measures direct observation and trace measures) for measuring
organizational effectiveness Next describe and justify the steps you would
take to develop an operationalization of the concept of organizational
effectiveness What standards and procedures would you use to determine if
your operationalization is valid
B9 One of the most important topics of recent research has been stress in the work
place One of the most important problems with understanding this literature is
the varying definitions and measurement of this construct Suppose you had
decided to investigate the relationship between stress at the work place and dual
career family happiness
a Since there are multiple ways to measure stress in the work place describe
two ways to do this Hint - avoid using two self-report measures
b Describe how you would decide on the best single measure In doing so
describe the steps you would take in evaluating your measure Be sure to define
your meaning of validity and reliability It is important that your measure have
all the necessary psychometric characteristics so that other scientist can trust the
results of your research
c Be certain that you answer the question Validity for what
d In order to understand the results of your study you need to compare your
measure of stress at work with other measures of this construct How would you
do that
B10 Assume that you have been hired by a national survey research company
Shash Inc to write items that will be used in a national survey of attitudes
toward capital punishment There are a number of criteria that can be used to
guide your item writing What are they Briefly describe five (5) such criteria
B11 Assume that you are going to conduct empirical research to determine the
impact of interpersonal trust on organizational decision making Describe and
justify the steps you might follow to develop an operationalization of the
interpersonal trust concept
B12 Assume that you are going to conduct empirical field research to assess the role
that employee empowerment plays in determining the level of organizational
commitment of employees Describe and justifyexplain the steps you would
follow to develop a valid and reliable operationalization of the concept of
employee empowerment
Explain the procedures and standards you would use to determine if your
operationalization is valid and reliable
How would you assess the construct validity of such a measure
Discuss issues concerning the level of observation of your measure and level of
analysis of the data
B13 Assume you are interested in developing a new scale to measure construct X
Further assume that you have used previous literature and your own conceptual
development to delineate 2 dimensions of X specifically XF1 and XF2
Describe the steps you would go through in developing testing and evaluating
this new scale With regard to testing and evaluating be sure to consider the
role of factor analysis (both exploratory and confirmatory) and item analysis
Also you will want to make sure that your new multidimensional scale shows
evidence of validity (several kinds) and reliability so be sure to examine these
issues and explain how specific information gathered from the above testing
contributes to these concerns
C) Reliability
4) What is reliability and why is it so important What are the different ways reliability can be
assessed and when is each appropriate
15) What does coefficient alpha assess What are the ways coefficient alpha can be increased
C1 Describe and discuss the concept of reliability and all of its various forms
including their assessment When is each form appropriate and what information
is provided by each index
C2 In establishing congruence between multiple measurements we often compute
indices of reliability andor indices of agreement These two types of indices
address very different questions Your task is to 1) Define reliability and
agreement 2) Explain when each is useful using examples in which one but not
the other is appropriate and 3) Briefly describe two reliability indices and two
agreement indices
C3 Explain reliability in terms of the classical test theory What are the
consequences of unreliable measures in hypothesis testing What are the factors
that may affect the reliability of a multi-item scale
IC
C4 Generalizability theory is used within IO psychology more often today
However most researchers continue to use Classical Test Theory
conceptualizations of error to determine reliability What are the implications of
using classical test theory versus generalizability theory to assess reliability
C5 In establishing congruence between measurements we often compute indices of
reliability andor agreement Define reliability and agreement Explain the
differences in reliability and agreement and describe under what conditions
assessing reliability is more appropriate and under what conditions assessing
agreement is more appropriate
C6 Define measurement reliability in terms of a specific measurement theory (eg
true test score theory domain sampling theory generalizability theory IRT)
Discuss the different approaches for estimating reliability and the contexts in
which each might be appropriate Use examples throughout
C7 What are the consequences of unreliability in a measure
C8 What are some of the conditions that might keep the internal consistency (eg
alpha) of a given measure low Is a low alpha always a sign of a problematic
measure
C9 Define reliability Name some methods of calculating reliability How well do
these methods map up with the definition of reliability What is the impact of the
number of test items and sample size on Chronbachs alpha and why would this
effect occur or not occur (Note Do NOT discuss inter-rater reliability)
C10 Schmidt and Hunter (1996) described several types of measures typically used in
organizational research and identified the type(s) of measurement error affecting
each of them in various situations For each measure below indicate the types of
error and sources of error that are most likely to affect it Then indicate what
could be done to reduce errors of measurement andor what can be done to
control for errors statistically
a Supervisor ratings of subordinates job performance
b Self-ratings of ones own job performance
c Self-reports of ones own job-related attitudes
d Sales figures for a salesperson (or production quantity for a production
worker)
d Aptitude tests taken as part of the hiring process
C11 Suppose you had conducted research on the relationship between organizational
commitment and rigidity of organizational structure in 200 firms Your measure
of rigidity was based on number of organizational authority levels and the degree
to which written organizational rules existed and defined role behaviors for
employees Thus an organization with a large number of organizational levels
and specific written policies defining appropriate role behaviors for employees
would score high on rigidity of organizational structure After analyzing your
data you find that there is a statistically significant negative correlation between
commitment and rigidity which is consistent with your hypothesis However the
reliabilities for your two measures are
(1) commitment = 23 (2) rigidity = 83
How should you interpret your results What could you do to fix this situation
Describe the specific steps (in order) you would follow to develop a more
reliable measure of commitment
C12 (a) Define the concept of reliability (of measures) in a clear concise and
accurate manner (b) Provide a formula that expresses the reliability of a measure
in terms of two components of variance ie total variance and the error
variance
D) Multi-level Assessment
D1 One of the major challenges for group-level research is the issue of aggregation of
individual data to the group level
(a) Under what conditions (eg types of data number of raters) should the various
interrater agreement and reliability methods be used (Rwg Kappa and Weighted
Kappa percent agreement average pairwise correlation ANOVA methods

D2 Cross-levelmulti-level research is becoming more evident in the organizational
research literature This type of research raises many issues and presents many
challenges in terms of designing the research measuring variables and collecting
and analyzing the data Assume that you are interested in aggregating data (eg
from the individual to the group or from the firm to the industry) for one or more
variables What are the major issues you will need to deal with
D3 A researcher wants to measure organizational climate for continuous learning
Organizational climate is operationalized as a shared consensual aspect of the
organization -- the shared perception among employees that the organization values
and supports continuous learning Describe how you would measure organizational
climate in this case Specify (a) the level (ie individual group organization) at
which the construct exists (b) the level at which you would measure the construct
and (c) the procedures that you would use to establish that measurement is aligned
with theory (ie the construct validity of the measure)
E) General (Measurement)
E1 Studies in organizational behavior research often rely on single-item measures of
key constructs The use of single-item measures has long been criticized based
on the premise that single-item measures are unreliable However Wanous
(Wanous amp Hudy 2001 Wanous amp Reichers 1996 Wanous Reichers amp Hudy
1997) has recently argued that single-item measures can exhibit adequate
reliability Wanous based this conclusion on a procedure for estimating the
reliability of single-item measures using the classic formula for correction for
attenuation Subsequent studies have yielded mixed results regarding the
conclusions of Wanous (eg Loo amp Kells 1998 Nagy 2002) and the veracity
of the perspective advocated by Wanous remains in question Summarize and
assess the arguments for and against the use of single-item measures and
evaluate the procedure and evidence offered by Wanous regarding the reliability
of single-item measures Based on your assessment and evaluation develop
recommendations regarding the use of single-item measures in organizational
behavior research

E2 Ipsative measures have become prevalent in organizational behavior research
Ipsative measures ask respondents to answer questions relative to one another
such that the scores for all questions sum to the same constant for all respondents
Examples of ipsative measures include rankings Q-sorts and the allocation of a
fixed number of points (eg 100) across a set of response options Ipsative
measures may be contrasted with absolute measures which ask respondents to
answer questions independently from one another Absolute measures are
exemplified by rating scales using an interval or ratio numeric response format
The relative merits of ipsative and absolute measures have been debated for
decades (eg Cornwell amp Dunlap 1994 Hicks 1970 Johnson Wood amp
Blinkhorn 1988 Saville amp Wilson 1991 1992) yet the fundamental issues
underlying this debate have not been adequately addressed in organizational
behavior research For example measures of organizational culture and values
are often ipsative and some researchers advocate these measures over absolute
measures (eg Meglino amp Ravlin 1987 OReilly Chatman amp Caldwell 1991
Ravlin amp Meglino 1987 see also Rokeach amp Ball-Rokeach 1989) Review the
relative merits of absolute and ipsative measures Based on your review which
form of measurement is most appropriate and why Do your conclusions depend
on the construct being measured If so what types of constructs are best suited to
ipsative measures and what types are best suited to absolute measures Next
apply your conclusions to the measurement of culture and values in
organizations What specific arguments have been advanced in favor of ipsative
measures of culture and values How sound are these arguments Should ipsative
measures be used in the study of organizational culture and values If not how
can absolute measures of culture and values be developed that address the
concerns voiced by advocates of ipsative measures Provide a specific example
of the type of measure you would propose

E3 In organizational research measures often consist of items that represent different
facets of a concept Although such measures are prevalent and in some cases are
advocated (eg Law et al 1998 1999) they can present a variety of conceptual
and methodological problems Describe the specific problems associated with
measures that use items representing different facets of a concept Compare these
problems with the purported advantages of such measures Conclude by

E5 Suppose Roberta Von Eisenbrick is a researcher interested in the consequences of
AFFECTIVE CONFLICT (AC) in decision-making teams She gets access to a
variety of outcomes assessment committees at each of 87 different schools in
the Dallas Independent School District and gains permission to tape-record two
of their meetings (one in February and one in March) Such committees have
been formed to develop quantitative ways to track pursuit of school goals and
provide accountability to local and state governments These are often divisive
teams with heated meetings because what gets assessed is what usually gets
rewarded After both of these meetings the committee members each
fill out a short questionnaire that contains 20 Likert-type items measuring how
much AC occurred (eg People in our group often get angry with each other)
The individual scores are summed across items then averaged across team
members to come up with a group-level AC score for each of the 87 2
meetings The same procedures are followed for a 5-item measure of Group
Cohesiveness (GC) which is predicted to be reduced by higher levels of AC
Roberta also listens to every tape and from her expert judgment she rates each
groups meetings on the same 20 items Those 20 ratings are summed for each of
the 87 2 meetings Now Roberta is interested in evaluating her measure She
wants it to have excellent psychometric properties including reliability and
construct validity

D) ModeratorsMediators
D1 Moderation and mediation provide different ways to model third variable effects
(a) Please define both of these terms (b) Sketch a conceptual model to show how
each relates to main effects (c) Using variables of your choice please write
hypotheses to reflect both (d) Explain how each is tested analytically
D2 Discuss moderators and mediators Provide an example of how (1) a moderating
variable influences the relationship between the independent and dependent
variable and how (2) a mediating variable influences the relationship between
the independent and dependent variable Describe how you would test for both
moderation and mediation using regression
D3 Many theories in organizational research predict that the effects of one variable
on another are moderated by a third variable Such moderator effects are
typically tested by entering the product of two variables as a predictor after
controlling for the two variables that constitute the product Several researchers
have pointed out that this product is often highly correlated with the squares of
the two constituent variables and have suggested that moderating effects may be
tested after controlling not only for the two constituent variables but also their
squares (eg Cortina 1993 Ganzach 1998 Lubinski amp Humphreys 1990
MacCallum amp Mar 1995) Discuss the strengths and weaknesses of this
approach as compared to methods that use only the product term and its
constituent variables Conclude with recommendations as to when and under
what conditions organizational researchers should test moderator effects with the
squares of the constituent variables in the equation

D4 Assume you are interested in studying relationships amongst three variables X
Y and Z Your first hypothesis posits Z as a mediator of the relationship between
X and Y Your second hypothesis posits Z as a moderator of the relationship
between X and Y Draw the figures depicting each of these hypothesized
relationships and describe (make sure to write regression equations) how you
would test each of these hypotheses
D5 The amount of time and effort that the average person pours into his or her job
has risen steadily over the last two decades such that the average person now is
working one more week per year than the average person in the mid 1970s This
steady increase has fueled research interest in the construct of Job Burnout (JB)
which is an emotional and physical exhaustion associated with ones work
Organizational Stress (OS) the perception of greater demands than available
resources in ones work environment is thought to be one of the chief
antecedents of JB However time spent under OS is thought to make its affects
on JB accumulate or worsen Work Role Withdrawal (WRW) the avoidance of
responsibilities or the deliberate reduction of inputs to ones job is believed to be
the chief consequence of JB
a Formally state these ideas as verbal hypotheses as equations and as a complex
directed graph (circle amp arrow diagram)
b Conceptually what is a mediator Define the term and identify the mediator in
your hypotheses in (a) What elements or steps in a study design (not statistics)
that would be helpful for detecting the mediating relationship that was proposed
c What is a moderator What are some of the other names for it within various
subdomains of management Further demonstrate your understanding of
moderator variables by picking which variable in (a) is the moderator Show the
moderating relationship in an X-Y (or multi-layered) chart Again what elements
or steps in a study design (not statistics) would be helpful for detecting the
moderating effect implied above
E) Multiple Comparisons
E1 In your role as professional colleague you are called upon to advise another doctoral
student about the appropriate use of multiple comparisons and post hoc tests in
analysis of variance Your student colleague already has been introduced to ANOVA
and multiple regression Specifically you are to write out a description of how to test
for differences among the different levels or cells of a categorical variable In your
description you should discuss among other things
a the statistical and philosophical issues raised by post hoc analysis and data
snooping
b the different multiple comparison methods commonly used by researchers to test
for differences among cell means and
c the advantages and disadvantages of each method

recommendations You conduct a well-designed controlled study (details are unimportant) and discover students who use the new book perform 10 better on a standardized subject
matter exam than those using the old book (p = 027) Both books are readily availabe their prices are almost identical and both are equally acceptable to the instructors What is your recommendation to the chair
F1 Attached is the beginning of an article Your task is to write the results section by
1 making up and reporting plausible descriptive statistics that will help the
reader understand the results of the statistical tests you report and the nature of your
sample (Hint this can be presented in the form of a table)
2 describing and defending your choice of appropriate statistical tests of the
hypotheses and the steps that you would go through in carrying out these tests
3 making up and reporting results of these tests that are consistent with your
descriptive statistics and with any information in the rest of the article about the
results found (Hint this can be presented in the form of a table)
4 describing how well these results provide support for the hypotheses You
may want to note any relevant threats to validity here
Be sure to state any assumptions you make
F2 Assume that the Personnel Manager of a local firm Ms B dFlandres hired you to
analyze some data that her assistants had collected over the past several years The
data consist of (a) job performance ratings that were made in June of 1990 and (b)
scores on 25 predictor variables (eg measures of education job experience job
tenure job aptitude personality) that were measured when the individuals were hired
(between April 1987 and May 1988) She had data from only the 110 subjects (60
males and 50 females) who were hired during the period and were still employed by
the firm One objective of your analysis (analyses) is to determine how well the
performance criterion can be predicted by the predictors What strategy would you
use in analyzing the data Describeexplain (b) Is sample size an issue for your
analyses Explain If it is what will you do to deal with problems stemming from
sample size Assume that no additional data can be collected at this time (c) Some
preliminary analyses that you do reveal that five of the predictor variables correlate
(zero-order basis) about 75 with one another Will this influence the analyses that
you use Will it influence the validity of conclusions derived from your proposed
analyses (d) Ms dFlandres is interested in knowing if the predictor variables are
equally effective in predicting the job success of males and females What analysis
or analyses would you do to deal with this issue
F3 Assume that you have been provided with data on 12 conceptually distinct variables
that are moderately correlated with one another at the empirical level The data are
from students in four different college majors ie astronomy (A) biology (B)
criminology (C) and demography (D) The 12 measured variables fall into the
general categories of mental health (tension emotional withdrawal hallucinations
guilt feelings blunted affect and suspiciousness) and job satisfaction (work itself
supervision co-workers pay promotion prospects and working conditions) Your
task is to determine if the individuals in the four college majors differ from one
another on the 12 measured variables
(a) What statistical technique(s) would you use to test for group differences
Explain Be specific about the procedures(s) that you would use
(b) What statistical estimate would you use to estimate the extent to which the
groups differ from one another Be specific
F4 The following statistical table published in a recent issue of Work amp Occupations
was taken from an article discussing variables influencing resistance and citizenship
behaviors in the workplace Resistance behaviors include playing dumb withholding
effort work avoidance subverting particular managers and sabotage Citizenship
behaviors include cooperation engaging in peer training use of insider knowledge to
facilitate production commitment to organizational goals giving extra effort freely
Both measures are global constructs aggregated to the interval level and
standardized
The table reports the results of a series of ordinary least squares regression equations
with standardized coefficients Explain the meaning of the statistics presented What
do these statistics tell us generally about the relationship between resistance
behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows
Anomie Index -standardized interval level measure tapping multiple dimensions
The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)
F5 Researchers collected data from a sample of 350 companies on the following
variables
size (measured as number of employees)
Business Strategy (a nominal variable with 2 response options low-cost provider or
differentiator)
HR Strategy (a nominal variable with 2 response categories High commitment or
low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

J) Meta-analysis
J1 There exist two categories of literature review narrative and quantitative Each
category as typically implemented has certain advantages and disadvantages
Describe the advantages and disadvantages associated with each approach taking
particular care to enumerate the disadvantages associated with quantitative review
Then offer two ways that meta-analysis might be combined with other analytical
techniques to move beyond the focus of bivariate relationships that is typical of meta-
analysis

scientific laws but that meta-analytic research does What are the arguments in favor
of or against this position In what areas of research (if any) has Schmidts
prediction come closest to coming true

mirrors Explain both sides of the debate and then lay out the role of meta-analysis
as you see it within the time span of your career as an academic To do this use
examples of already written (or yet to be written) articles as models
J5 A frequent criticism of non-quantitative research summaries (literature reviews) is
that researchers do not carefully examine how particular research designs might have
affected the statistical outcomes of the studies included in the literature review Meta-
analysis however allows one to statistically examine such effects Assume you are
conducting a meta-analysis of the relationship between leader behaviors and group
productivity Briefly describe the steps you would take in conducting a meta-
analysis What aspects of the original research designs would you examine in your
meta-analysis What steps would you take in gathering and coding data to enhance
the credibility of your analysis
K) MTMM
K1 One method often used by social scientists to demonstrate the construct validity of
measures is the multi-trait multi-method matrix developed by Campbell and
Fiske (1959) Briefly describe how this matrix is obtained or constructed by a
researcher and then describe how each of the elements of the matrix is used to
demonstrate the reliability andor construct validity of the measure(s)
IC
K2 Describe the logic of the multi-trait multi-method (MTMM) analysis in terms of
the criteria for evaluating the validity of a set of measurement procedures
Interpret the following MTMM in terms of what it might infer about the validity
of the different measurement procedures You may impose any assumptions on
the data you prefer For example you might want to discuss the matrix under the
assumption that traits A B amp C are mutually independent Please justify and
make explicit any assumptions you make

2) offer and describe substantive examples to which each approach is uniquely
suited and 3) describe how interactions among categorical variables are examined
in regression
L2 Categorical variables can be analyzed in regression using design variables The

O3 How do exploratory and confirmatory factor analysis differ What are the
advantages and disadvantages of each
O4 Describe the differences between exploratory factor analysis (EFA) and
confirmatory factor analysis (CFA) When would you use one verses another
Are there ways to use EFA in a confirmatory way Can you use CFA in an
exploratory way Also describe the difference in principal components analysis
(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression
O6 The basic factor analysis model can be represented by the matrix algebraic
equation A B = C
(1) What do each of these matrices represent Be specific as to the type of
information in each matrix and its purpose
(2) For what purpose do researchers use factor analysis Explain In the process
provide a very brief description of a study for which factor analysis would be a
useful data analytic technique
O7 Factor analysis is an important statistical technique in organizational research
Describe factor analysis as an analytical tool including the following issues
a the reasons for using factor analysis
b the type of data necessary for using the technique appropriately
c the type of quantitative output that results from applying the technique
d how a researcher would use the output in his or her research
e how confirmatory factor analysis is different from exploratory
f the important issues and problems in using the technique
P) Structural Equation Models
P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

parameter estimate bias in structural equation modeling Structural Equation

Marsh H W Hau K T Balla J R amp Grayson D (1998) Is more ever too
much The number of indicators per factor in confirmatory factor analysis
Multivariate Behavioral Research 33 181-220
P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)
Please comment on these restrictions versus access argument Which side do you
take
What are the strengths of SEM Give some examples
What are the weaknesses of SEM Give some examples

extra paid vacation days for safety behaviors in terms of accident-free days
weeks etc Your task is to devise an approach (a research strategy a design a
set of measures and a general analysis strategy) that will allow you to evaluate
the safety program Because of the potential for the influence of many

B10 One of the most important areas of research is forecasting of human resources
needs based on strategic positions of organizations For example NY State must
carefully forecast its human resources needs as it proceeds with significant lay-
offs of state employees Future human resources needs are generally evaluated
by either statistical ie regression or simulation or clinical judgment i e
supervisors judgments methods

statistical or judgmental methods are better for forecasting human resources
needs You may discuss a program of research but please be quite specific in
your description of the first study
b What are the critical methodological issues in doing this kind of research
c What are the critical applied (or practical) issues in doing this research
d Are the issues in b and c related
B11 In the past decade computinginformation technology has changed many
aspects of organizational life For example the technology can make increased
decentralization possible by improving communication between central offices
and field offices Computer networks and word processors can enhance group
empowerment by making it possible for team members to create and edit
written group products quickly even if the individuals are at different locations
Some have argued that computinginformation technology will foster the
paperless productive office nevertheless others argue that the technology only
increases paper and reduces office productivity You are applying to the
National Science Foundation for a grant to conduct research that examines the
impact of computing information technology on organizational decision
processes The NSF application procedure imposes five basic requirements that
your research design must fulfill in order to receive funding Note A very
significant factor affecting NSF grant decisions is a clear demonstration that the
researcher is knowledgeable about the research methodology used Write your
response to each of the following five grant requirements Be sure not only to
respond to the requirement but also to demonstrate your research
competence
1You must design a study that uses two different methods
(interviewobservation survey experiment or quasi-experiment) Describe your
two methods in detail and provide a rationale for the key elements (eg
sampling data collection proposed analysis) of your methods Be sure to
discuss and evaluate the internal and external validity of both methods
2 As part of your research design you must select a conceptual (latent) variable
central to your proposal (use centralization of decision making as your
variable) and describe how you will develop your own measure (You may not
simply use off the shelf instruments)
3 You must describe how you will test for the reliability of the measure
(centralization of decision making) you developed in step 2 The NSF insists
that you describe how you will evaluate both the temporal stability and the
internal consistency of your measure Be sure to discuss what temporal stability
and internal reliability mean and how they are related
4You must describe how you will assess the validity of the measure
(centralization of decision making) you developed in step 2
5 NSF requires a brief statement and defense of the philosophy of science
underlying your research Discuss your position and show how your research
design is consistent with your philosophy
B12 Many organizations in the United States economy have installed some form of
Empowered Teams as an alternative or supplement to traditional bureaucratic
structure Preliminary evidence of the effectiveness of empowered teams
however is mixed--some organizations have claimed success and others have
reported failures The evidence however is predominantly anecdotal--written
for trade magazines by the organizations themselves There are few rigorous
empirical studies assessing the effectiveness of empowered or self-managed
teams You are applying to the United States Department of Labor (USDOL) for
a grant to conduct research that examines the effectiveness of empowered
teams The application procedure of the USDOL imposes three requirements
that your research design must fulfill in order to receive funding Write your
response to each of the three grant requirements The importance of each section
is implied by the evaluation points allocated by the USDOL to each of the three
requirements given in parentheses
1 (50 points) Your study design for assessing Empowered Team effectiveness
must use two different methods (interview observation archival analysis
survey simulation experiment or quasi-experiment) Describe in detail and
thoroughly explain the sampling plan instrumentation data collection
procedures and proposed data analyses for both methods Be sure to discuss the
internal and external validity of both methods and how the two methods
complement one another
2 (30 points) As part of your research design you must select one conceptual
(latent) variable central to your proposal and describe how you will develop
your own operationalization of the measure (You may not simply use off the
shelf instruments) Use the concept of group morale to demonstrate your
operationalization methodology Be sure to explain very explicitly to the
USDOL how you will assess the validity and reliability of the group morale
measure you are developing
3 (20 points) The USDOL traditionally has funded research conducted only
within the general paradigm of logical positivism but now is more open to other
research paradigms as well Your grant proposal must provide a statement and
defense of the explicit philosophy of science underlying your research Describe
your philosophy of science and show how your research design is consistent
with your philosophy
REMEMBER Be thorough You not only must design effective research but
you also must demonstrate to the USDOL that you are a competent researcher
It is absolutely vital to the USDOL that the principal researcher is
knowledgeable about the proposed research methodologies Therefore be sure
that you always carefully describe and give technical explanations for each
component of your research design and explain all technical terms (eg
Cronbach alpha KR-20 Likert scale)
B13 Assume that you are working as part of a research team that is responding to a
RFP (Request for Proposals) from a funding agency for research on work
socialization and newcomer adjustment The RFP calls for rigorous field
research that tests the effectiveness of theory-based interventions aimed at
facilitating the adjustment of new organizational members to complex andor
stressful work conditions The major goal of your teams research is to test the
effectiveness of a self-regulation intervention which trains newcomers to
identify and use relevant social information and cues to regulate work behavior
Your group hypothesizes that self-regulation training will be more effective
than other common treatments or interventions (eg realistic job previews
institutionalized socialization tactics)
You have been included in the team because of your methodological expertise
Your role is to design a rigorous field experiment or quasi-experiment to test he
effectiveness of the self-regulation training program REMEMBER THE
MAJOR CRITERION FOR FUNDING IS THE RIGOR OF THE RESEARCH
DESIGN Design a field study to include in the grant proposal Your proposal
should contain the following two sections
1 Study Design Construct and describe in detail an experimental or quasi-
experimental design to test the effectiveness of your intervention Describe in
detail the experimental groups (including how they will be constructed) the
research setting the sampling plan for study participants the treatment
manipulation and the data collection procedures Also indicate any control or
nuisance variables that may be measured
After describing the procedures write a justification of the design What threats
to validity does it rule out or limit and what threats to validity remain
II Measurement Describe the steps you would take to achieve valid and
reliable measure of the latent (conceptual) variable worker adjustment Your
team feels that as part of the proposal you must develop an original
operationalization of adjustment (thus you cannot simply use existing off the
shelf measures) Indicate in adequate detail how you would operationalize the
measure and indicate how you would demonstrate reliability and validity
B14 In describing their notion of the collective mind Karl E Weick and Karlene H
Roberts note Our focus is at once on individuals and the collective since only
individuals can contribute to a collective mind but a collective mind is distinct
from an individual because it inheres in the pattern of interrelated activities
among many people (p 360) Collective mind is not indexed by within-group
similarity of attitudes ideas or activities A collective mind is one in which
many people or many groups integrate their different attitudes ideas and
activities heedfully As Weick and Roberts note People act heedfully when
they act more or less carefully critically consistently purposefully attentively
studiously vigilantly conscientiously pertinaciously (p 361)
The idea of the collective mind as heedful interrelating is developed in the
following excerpt When people make efforts to interrelate these efforts can
range from heedful to heedless The more heed reflected in a pattern of
interrelations the more developed the collective mind and the greater the
capability to comprehend unexpected events that evolve rapidly in unexpected
ways When we say that a collective mind comprehends unexpected events we
mean that heedful interrelating connects sufficient know-how to meet situational
demands For organizations concerned with reliability those developments
often consist of unexpected non-sequential interaction (p366)
An example of heedful interrelating occurs as a pilot lands herhis aircraft on the
deck of an aircraft carrier The pilot does not actually land She is recovered
A recovery is an interrelated set of activities among air traffic controllers
landing signal officers the control tower navigators deck hands the helmsman
driving the ship etc These activities can be interrelated more or less heedfully
depending on the care with which the different units contribute represent the
situation and subordinate their activities to the single purpose of successful
recovery (p 363)
You are to design a two-part study
Part I You are to design a measurement study which assesses heedful
interrelating (ie collective mind) with a quantitative measure in a replication
of an aircraft carrier flight deck or other situation of your choosing Describe
your research strategies including operationalization of the variable selection of
the sample subjects data collection data analysis and so on for the purpose of
developing a measure of heedful interrelating
Part II Using the measurement tool developed in Part I and any other tools as
needed describe how you would design a study which would compare heedful
interrelating across organizations Choose at least one macro-organizational
variable (eg technology environment) as your basis of comparison Here you
must describe how you would make your selection of organizations to be
compared your data collection procedure data analysis and so on
B15 Many organizations in the United States have installed cross-functional teams to
counteract the silo mentality of traditional bureaucratic structure Preliminary
evidence of the effectiveness of cross-functional teams however is mixed --
some organizations have claimed success and others have reported failures The
evidence moreover is predominantly anecdotal--written for trade magazines by
the organizations themselves Since there have been few rigorous empirical
field studies assessing the effectiveness of cross functional teams the National
Science Foundation has decided to fund research on the topic
Assume that you are submitting a research proposal to NSF for a grant to
research the effectiveness of cross-functional teams Describe in detail and
thoroughly explain the research design sampling plan data collection
procedures ethical issues and proposed data analysis for your research design
Be sure to discuss the internal and external validity of your research Which
validity threats are ruled out and which remain NSF also requires that you
provide a statement and defense of the explicit philosophy of science underlying
your research Describe your philosophy of science and discuss how your
research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but
you must also demonstrate to NSF that you are a competent researcher It is
absolutely vital to NSF that the principal researcher (you) is knowledgeable
about the proposed research methodologies Therefore be sure that you always
carefully describe and give technical explanations for each component of your
research design and explain all technical terms (eg Cronbach alpha KR-20
Likert scale)
B16 Assume that you are submitting a research proposal to the Department of
Commerce (DoC) for a grant to research the effectiveness of virtual work teams
A virtual work team is a leaderless collection of individuals who are
geographically separate from one another and share their expertise using
internet media such as a listserver or Lotus notes The DoC requires that the
researcher use both qualitative and quantitative methods to gather data Describe
in detail and thoroughly explain the research design sampling plan data
collection procedures ethical issues and proposed data analysis for your
research design Be sure to discuss the internal and external validity of your
research Which validity threats are ruled out and which remain The DoC also
requires that you provide a statement and defense of the explicit philosophy of
science underlying your research Describe your philosophy of science and
discuss how your research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but
you must also demonstrate to DoC that you are a competent researcher It is
absolutely vital to DoC that the principal investigator (you) is knowledgeable
about the proposed research methodologies Therefore be sure that you always
carefully describe and give technical explanations for each component of your
research

5 MEASUREMENT
A) Measurement Terms
A1 There are four levels of measurement rigor in management research Discuss each
one What properties do measurements at each level have (ie how much
information do the numbers from each level of measurement convey) How can the
numbers be changed (transformed) and still retain the properties of their
measurement level Pick one construct from a favorite research domain and give an
example of an operationalization of that construct at each of the four levels of
measurement rigor (provide arguments about why you think those examples reflect
each level) Lastly treat each examplelevel as a dependent variable in some
statistical analysis Given an example of a statistical technique appropriate for
analyzing data at that level of measurement rigor
A2 Define (and discuss important features or issues concerning) the following
constructs measurement (Define any six terms)
1 Construct validity 6 Item analysis
2 Likert scaling 7 Semantic differential
3 Cronbachs alpha 8 True score
4 Unobtrusive (trace) measurement 9 Generalizability theory
5 Interval scale 10 Criterion-related validity
11 Sociometric choice measures
B) Operationalization
B1 a) You are conducting a study which requires you to measure Hong Kong real
estate agents self-assessment of performance Since there is no existing
measurement available you have to develop the instrument by yourself
Describe how you would develop the measurement assuming that you have no
idea of how many dimension the construct has
b) Suppose you have developed an instrument consists of 20 questions
measuring 4 dimensions (5 items per dimension) from (a) You collected data
from another 300 real estate agents to validate your instrument Explain how
TH
you would use structural equations model (SEM) to examine the reliability and
validity of the instrument What are other concerns about reliability and validity
that are not addressed by this approach
B2 The research and business world have been fascinated with the concept of
organizational culture However operationalizing this construct has been a
difficult task Discuss the ways in which the construct has been operationalized
(eg technique static v dynamic sample selection generalizability) Critically
analyze each of these methodologies Then choose a methodology you would
use to examine organizational culture and defend your choice Describe how
you would study culture and what more would be known about culture as a
result of your study
B3 Suppose you are setting out to develop a new measure of a construct You want
this measure to be used in survey research and you want to establish its validity
and reliability Your goal is to have at the end of the process a measure that is
defensible and likely to be widely accepted by other researchers studying that
construct What steps would you take to conduct such a program of research
For each step explain the purpose of that step explain why that step is
important explain what methods and statistical procedures you would employ at
each step and explain what evidence you would hope to gather at each step
B4 Assume you are interested in constructing a new measure of (fill in with a
relevant variable from your field) Detail the major concerns that need to be
addressed and the steps that need to be taken in working toward validating this
new measure
B5 Assume that you recently read an article on workplace violence which you
found very interesting The authors argued that one of the predictors of
workplace violence was a construct called propensity to be violent and used a
one-item measure as follows How likely are you to become violent when
provoked You had serious doubts about the authors measure and decided to
develop your own
(a) How would you go about developing items to measure propensity to be
violent
(b) How would you determine whether the instrument was reliable
How would you determine whether the instrument was valid
B6 A concern in organizations is retirement of baby boomers within the next 5 -
10 years This concern is focused on the loss of older employees with skills
critical to the core business functions of organizations In order to continue to
have employees with those critical skills it seems necessary to retrain some
older workers However past practice in most organizations has been not to
retrain older workers for a variety of reasons mostly financial A researcher
working for the Human Resources Department of a large corporation - 13500
employees in 12 different plant locations - hypothesizes that the major reason
for not retraining older workers is ingrained in the culture of the corporation
IC
The researcher feels that older workers are not as highly valued as younger
workers in terms of their potential usefulness after retraining The researcher
searched the literature but found nothing in the existing literature to measure
the cultural value construct What should the researcher do to establish a reliable
and valid self-administered paper and pencil measure of this construct namely
the value of retraining older workers
a Please describe and explain the steps in temporal order that the researcher
must follow to develop a measure
b How would you evaluate the measure based on the technical requirements of
reliable and valid measurement as well as any practical issues in using the
measure considering the size of the employee population
B7 Assume that you are going to conduct empirical research to assess the role that
the complexity of an organizations manufacturing technology plays in
determining the level of centrality of decision making in the organization
Describe and justify the steps you might follow to develop an operationalization
of the concept of technological complexity What standards would you use to
determine if your operationalization is valid
B8 Organizational researchers have several strategies available to them for
gathering information (eg self-report measures archival measures direct
observation and trace measures) Assume that you are going to conduct
empirical research to assess the role that the structure of the organization plays
in determining the level of organizational effectiveness Briefly review the
strengths and weaknesses of the basic strategies (that is self-report measures
archival measures direct observation and trace measures) for measuring
organizational effectiveness Next describe and justify the steps you would
take to develop an operationalization of the concept of organizational
effectiveness What standards and procedures would you use to determine if
your operationalization is valid
B9 One of the most important topics of recent research has been stress in the work
place One of the most important problems with understanding this literature is
the varying definitions and measurement of this construct Suppose you had
decided to investigate the relationship between stress at the work place and dual
career family happiness
a Since there are multiple ways to measure stress in the work place describe
two ways to do this Hint - avoid using two self-report measures
b Describe how you would decide on the best single measure In doing so
describe the steps you would take in evaluating your measure Be sure to define
your meaning of validity and reliability It is important that your measure have

this new scale With regard to testing and evaluating be sure to consider the
role of factor analysis (both exploratory and confirmatory) and item analysis

C10 Schmidt and Hunter (1996) described several types of measures typically used in
organizational research and identified the type(s) of measurement error affecting
each of them in various situations For each measure below indicate the types of
error and sources of error that are most likely to affect it Then indicate what
could be done to reduce errors of measurement andor what can be done to
control for errors statistically

worker)
d Aptitude tests taken as part of the hiring process
C11 Suppose you had conducted research on the relationship between organizational
commitment and rigidity of organizational structure in 200 firms Your measure
of rigidity was based on number of organizational authority levels and the degree
to which written organizational rules existed and defined role behaviors for
employees Thus an organization with a large number of organizational levels
and specific written policies defining appropriate role behaviors for employees
would score high on rigidity of organizational structure After analyzing your
data you find that there is a statistically significant negative correlation between
commitment and rigidity which is consistent with your hypothesis However the
reliabilities for your two measures are
(1) commitment = 23 (2) rigidity = 83
How should you interpret your results What could you do to fix this situation
Describe the specific steps (in order) you would follow to develop a more
reliable measure of commitment

data
(e) Provide some ideas for avoiding the need to aggregate in group-level research

research literature This type of research raises many issues and presents many
challenges in terms of designing the research measuring variables and collecting
and analyzing the data Assume that you are interested in aggregating data (eg
from the individual to the group or from the firm to the industry) for one or more
variables What are the major issues you will need to deal with
D3 A researcher wants to measure organizational climate for continuous learning
Organizational climate is operationalized as a shared consensual aspect of the
organization -- the shared perception among employees that the organization values
and supports continuous learning Describe how you would measure organizational
climate in this case Specify (a) the level (ie individual group organization) at
which the construct exists (b) the level at which you would measure the construct
and (c) the procedures that you would use to establish that measurement is aligned
with theory (ie the construct validity of the measure)
E) General (Measurement)
E1 Studies in organizational behavior research often rely on single-item measures of
key constructs The use of single-item measures has long been criticized based
on the premise that single-item measures are unreliable However Wanous
(Wanous amp Hudy 2001 Wanous amp Reichers 1996 Wanous Reichers amp Hudy
1997) has recently argued that single-item measures can exhibit adequate
reliability Wanous based this conclusion on a procedure for estimating the
reliability of single-item measures using the classic formula for correction for
attenuation Subsequent studies have yielded mixed results regarding the
conclusions of Wanous (eg Loo amp Kells 1998 Nagy 2002) and the veracity
of the perspective advocated by Wanous remains in question Summarize and
assess the arguments for and against the use of single-item measures and
evaluate the procedure and evidence offered by Wanous regarding the reliability
of single-item measures Based on your assessment and evaluation develop
recommendations regarding the use of single-item measures in organizational
behavior research

E2 Ipsative measures have become prevalent in organizational behavior research
Ipsative measures ask respondents to answer questions relative to one another
such that the scores for all questions sum to the same constant for all respondents
Examples of ipsative measures include rankings Q-sorts and the allocation of a
fixed number of points (eg 100) across a set of response options Ipsative
measures may be contrasted with absolute measures which ask respondents to
answer questions independently from one another Absolute measures are
exemplified by rating scales using an interval or ratio numeric response format
The relative merits of ipsative and absolute measures have been debated for
decades (eg Cornwell amp Dunlap 1994 Hicks 1970 Johnson Wood amp
Blinkhorn 1988 Saville amp Wilson 1991 1992) yet the fundamental issues
underlying this debate have not been adequately addressed in organizational
behavior research For example measures of organizational culture and values
are often ipsative and some researchers advocate these measures over absolute
measures (eg Meglino amp Ravlin 1987 OReilly Chatman amp Caldwell 1991
Ravlin amp Meglino 1987 see also Rokeach amp Ball-Rokeach 1989) Review the
relative merits of absolute and ipsative measures Based on your review which
form of measurement is most appropriate and why Do your conclusions depend
on the construct being measured If so what types of constructs are best suited to
ipsative measures and what types are best suited to absolute measures Next
apply your conclusions to the measurement of culture and values in
organizations What specific arguments have been advanced in favor of ipsative
measures of culture and values How sound are these arguments Should ipsative
measures be used in the study of organizational culture and values If not how
can absolute measures of culture and values be developed that address the
concerns voiced by advocates of ipsative measures Provide a specific example
of the type of measure you would propose

facets of a concept Although such measures are prevalent and in some cases are
advocated (eg Law et al 1998 1999) they can present a variety of conceptual
and methodological problems Describe the specific problems associated with
measures that use items representing different facets of a concept Compare these
problems with the purported advantages of such measures Conclude by

E5 Suppose Roberta Von Eisenbrick is a researcher interested in the consequences of
AFFECTIVE CONFLICT (AC) in decision-making teams She gets access to a
variety of outcomes assessment committees at each of 87 different schools in
the Dallas Independent School District and gains permission to tape-record two
of their meetings (one in February and one in March) Such committees have
been formed to develop quantitative ways to track pursuit of school goals and
provide accountability to local and state governments These are often divisive
teams with heated meetings because what gets assessed is what usually gets
rewarded After both of these meetings the committee members each
fill out a short questionnaire that contains 20 Likert-type items measuring how
much AC occurred (eg People in our group often get angry with each other)
The individual scores are summed across items then averaged across team
members to come up with a group-level AC score for each of the 87 2
meetings The same procedures are followed for a 5-item measure of Group
Cohesiveness (GC) which is predicted to be reduced by higher levels of AC
Roberta also listens to every tape and from her expert judgment she rates each
groups meetings on the same 20 items Those 20 ratings are summed for each of
the 87 2 meetings Now Roberta is interested in evaluating her measure She
wants it to have excellent psychometric properties including reliability and
construct validity

D) ModeratorsMediators
D1 Moderation and mediation provide different ways to model third variable effects
(a) Please define both of these terms (b) Sketch a conceptual model to show how
each relates to main effects (c) Using variables of your choice please write
hypotheses to reflect both (d) Explain how each is tested analytically
D2 Discuss moderators and mediators Provide an example of how (1) a moderating
variable influences the relationship between the independent and dependent
variable and how (2) a mediating variable influences the relationship between
the independent and dependent variable Describe how you would test for both
moderation and mediation using regression
D3 Many theories in organizational research predict that the effects of one variable
on another are moderated by a third variable Such moderator effects are
typically tested by entering the product of two variables as a predictor after
controlling for the two variables that constitute the product Several researchers
have pointed out that this product is often highly correlated with the squares of
the two constituent variables and have suggested that moderating effects may be
tested after controlling not only for the two constituent variables but also their
squares (eg Cortina 1993 Ganzach 1998 Lubinski amp Humphreys 1990
MacCallum amp Mar 1995) Discuss the strengths and weaknesses of this
approach as compared to methods that use only the product term and its
constituent variables Conclude with recommendations as to when and under
what conditions organizational researchers should test moderator effects with the
squares of the constituent variables in the equation

D4 Assume you are interested in studying relationships amongst three variables X
Y and Z Your first hypothesis posits Z as a mediator of the relationship between
X and Y Your second hypothesis posits Z as a moderator of the relationship
between X and Y Draw the figures depicting each of these hypothesized
relationships and describe (make sure to write regression equations) how you
would test each of these hypotheses
D5 The amount of time and effort that the average person pours into his or her job
has risen steadily over the last two decades such that the average person now is
working one more week per year than the average person in the mid 1970s This
steady increase has fueled research interest in the construct of Job Burnout (JB)
which is an emotional and physical exhaustion associated with ones work
Organizational Stress (OS) the perception of greater demands than available
resources in ones work environment is thought to be one of the chief
antecedents of JB However time spent under OS is thought to make its affects
on JB accumulate or worsen Work Role Withdrawal (WRW) the avoidance of
responsibilities or the deliberate reduction of inputs to ones job is believed to be
the chief consequence of JB
a Formally state these ideas as verbal hypotheses as equations and as a complex
directed graph (circle amp arrow diagram)
b Conceptually what is a mediator Define the term and identify the mediator in
your hypotheses in (a) What elements or steps in a study design (not statistics)
that would be helpful for detecting the mediating relationship that was proposed

subdomains of management Further demonstrate your understanding of
moderator variables by picking which variable in (a) is the moderator Show the
moderating relationship in an X-Y (or multi-layered) chart Again what elements
or steps in a study design (not statistics) would be helpful for detecting the
moderating effect implied above

for differences among the different levels or cells of a categorical variable In your
description you should discuss among other things

recommendations You conduct a well-designed controlled study (details are unimportant) and discover students who use the new book perform 10 better on a standardized subject
matter exam than those using the old book (p = 027) Both books are readily availabe their prices are almost identical and both are equally acceptable to the instructors What is your recommendation to the chair
F1 Attached is the beginning of an article Your task is to write the results section by

reader understand the results of the statistical tests you report and the nature of your
sample (Hint this can be presented in the form of a table)
2 describing and defending your choice of appropriate statistical tests of the
hypotheses and the steps that you would go through in carrying out these tests
3 making up and reporting results of these tests that are consistent with your
descriptive statistics and with any information in the rest of the article about the
results found (Hint this can be presented in the form of a table)
4 describing how well these results provide support for the hypotheses You
may want to note any relevant threats to validity here
Be sure to state any assumptions you make
F2 Assume that the Personnel Manager of a local firm Ms B dFlandres hired you to
analyze some data that her assistants had collected over the past several years The
data consist of (a) job performance ratings that were made in June of 1990 and (b)
scores on 25 predictor variables (eg measures of education job experience job
tenure job aptitude personality) that were measured when the individuals were hired
(between April 1987 and May 1988) She had data from only the 110 subjects (60
males and 50 females) who were hired during the period and were still employed by
the firm One objective of your analysis (analyses) is to determine how well the
performance criterion can be predicted by the predictors What strategy would you
use in analyzing the data Describeexplain (b) Is sample size an issue for your
analyses Explain If it is what will you do to deal with problems stemming from
sample size Assume that no additional data can be collected at this time (c) Some
preliminary analyses that you do reveal that five of the predictor variables correlate
(zero-order basis) about 75 with one another Will this influence the analyses that
you use Will it influence the validity of conclusions derived from your proposed
analyses (d) Ms dFlandres is interested in knowing if the predictor variables are
equally effective in predicting the job success of males and females What analysis
or analyses would you do to deal with this issue
F3 Assume that you have been provided with data on 12 conceptually distinct variables
that are moderately correlated with one another at the empirical level The data are
from students in four different college majors ie astronomy (A) biology (B)
criminology (C) and demography (D) The 12 measured variables fall into the
general categories of mental health (tension emotional withdrawal hallucinations
guilt feelings blunted affect and suspiciousness) and job satisfaction (work itself
supervision co-workers pay promotion prospects and working conditions) Your
task is to determine if the individuals in the four college majors differ from one
another on the 12 measured variables
(a) What statistical technique(s) would you use to test for group differences
Explain Be specific about the procedures(s) that you would use
(b) What statistical estimate would you use to estimate the extent to which the
groups differ from one another Be specific
F4 The following statistical table published in a recent issue of Work amp Occupations
was taken from an article discussing variables influencing resistance and citizenship
behaviors in the workplace Resistance behaviors include playing dumb withholding
effort work avoidance subverting particular managers and sabotage Citizenship
behaviors include cooperation engaging in peer training use of insider knowledge to
facilitate production commitment to organizational goals giving extra effort freely
Both measures are global constructs aggregated to the interval level and
standardized
The table reports the results of a series of ordinary least squares regression equations
with standardized coefficients Explain the meaning of the statistics presented What
do these statistics tell us generally about the relationship between resistance
behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows
Anomie Index -standardized interval level measure tapping multiple dimensions
The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)
F5 Researchers collected data from a sample of 350 companies on the following
variables
size (measured as number of employees)
Business Strategy (a nominal variable with 2 response options low-cost provider or
differentiator)
HR Strategy (a nominal variable with 2 response categories High commitment or
low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

I2 A study examined the effects of gender and pre-training motivation on the transfer of
training in terms of improved performance for 123 new industrial managers The
training was on supervisory skills and the dependent variable was based on the
appraisal of the supervisors performance before the training and three months after
the training The performance appraisal data were collected for research purposes
only and resulted in a total transfer score from 1 to 25 with 1 being low Pre-training
motivation was based on a 12 item Likert scale with an alpha of 86 Two groups

J) Meta-analysis
J1 There exist two categories of literature review narrative and quantitative Each
category as typically implemented has certain advantages and disadvantages
Describe the advantages and disadvantages associated with each approach taking
particular care to enumerate the disadvantages associated with quantitative review
Then offer two ways that meta-analysis might be combined with other analytical
techniques to move beyond the focus of bivariate relationships that is typical of meta-
analysis
J2 Schmidt has argued that primary research does not allow one to discover general
scientific laws but that meta-analytic research does What are the arguments in favor
of or against this position In what areas of research (if any) has Schmidts
prediction come closest to coming true
J3 The so-called (by Hunter Schmidt and Jackson 1983) state of the art meta-
analysis method attempts to account for various sources of error that might produce
apparent variation in effect sizes across studies (a) Discuss the three most important
sources of error that meta-analysis addresses (b) Discuss the potential contribution
that a meta-analysis can make to theory building in the organizational sciences (c)
Describe the circumstances that you would consider when deciding whether to
perform a meta-analysis
J4 Meta-analysis has been hailed as a miracle cure and criticized as smoke and
mirrors Explain both sides of the debate and then lay out the role of meta-analysis
as you see it within the time span of your career as an academic To do this use
examples of already written (or yet to be written) articles as models
J5 A frequent criticism of non-quantitative research summaries (literature reviews) is
that researchers do not carefully examine how particular research designs might have
affected the statistical outcomes of the studies included in the literature review Meta-
analysis however allows one to statistically examine such effects Assume you are
conducting a meta-analysis of the relationship between leader behaviors and group
productivity Briefly describe the steps you would take in conducting a meta-
analysis What aspects of the original research designs would you examine in your
meta-analysis What steps would you take in gathering and coding data to enhance
the credibility of your analysis
K) MTMM
K1 One method often used by social scientists to demonstrate the construct validity of
measures is the multi-trait multi-method matrix developed by Campbell and
Fiske (1959) Briefly describe how this matrix is obtained or constructed by a
researcher and then describe how each of the elements of the matrix is used to
demonstrate the reliability andor construct validity of the measure(s)
IC
K2 Describe the logic of the multi-trait multi-method (MTMM) analysis in terms of
the criteria for evaluating the validity of a set of measurement procedures
Interpret the following MTMM in terms of what it might infer about the validity
of the different measurement procedures You may impose any assumptions on
the data you prefer For example you might want to discuss the matrix under the
assumption that traits A B amp C are mutually independent Please justify and
make explicit any assumptions you make

model For each of those three statistical procedures describe and discuss the
following
a The type of data necessary for using the technique appropriately

O1 Contrast Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis
(CFA) Give an example for the appropriate use of each of the above analyses

assumptions usage and limitations
O3 How do exploratory and confirmatory factor analysis differ What are the
advantages and disadvantages of each
O4 Describe the differences between exploratory factor analysis (EFA) and
confirmatory factor analysis (CFA) When would you use one verses another
Are there ways to use EFA in a confirmatory way Can you use CFA in an
exploratory way Also describe the difference in principal components analysis
(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression
O6 The basic factor analysis model can be represented by the matrix algebraic
equation A B = C
(1) What do each of these matrices represent Be specific as to the type of
information in each matrix and its purpose
(2) For what purpose do researchers use factor analysis Explain In the process
provide a very brief description of a study for which factor analysis would be a
useful data analytic technique
O7 Factor analysis is an important statistical technique in organizational research
Describe factor analysis as an analytical tool including the following issues
a the reasons for using factor analysis
b the type of data necessary for using the technique appropriately
c the type of quantitative output that results from applying the technique
d how a researcher would use the output in his or her research
e how confirmatory factor analysis is different from exploratory
f the important issues and problems in using the technique
P) Structural Equation Models
P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

parameter estimate bias in structural equation modeling Structural Equation

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)
Please comment on these restrictions versus access argument Which side do you
take
What are the strengths of SEM Give some examples
What are the weaknesses of SEM Give some examples

carefully forecast its human resources needs as it proceeds with significant lay-
offs of state employees Future human resources needs are generally evaluated
by either statistical ie regression or simulation or clinical judgment i e

your description of the first study
b What are the critical methodological issues in doing this kind of research
c What are the critical applied (or practical) issues in doing this research
d Are the issues in b and c related
B11 In the past decade computinginformation technology has changed many
aspects of organizational life For example the technology can make increased
decentralization possible by improving communication between central offices
and field offices Computer networks and word processors can enhance group
empowerment by making it possible for team members to create and edit
written group products quickly even if the individuals are at different locations
Some have argued that computinginformation technology will foster the
paperless productive office nevertheless others argue that the technology only
increases paper and reduces office productivity You are applying to the
National Science Foundation for a grant to conduct research that examines the
impact of computing information technology on organizational decision
processes The NSF application procedure imposes five basic requirements that
your research design must fulfill in order to receive funding Note A very
significant factor affecting NSF grant decisions is a clear demonstration that the
researcher is knowledgeable about the research methodology used Write your
response to each of the following five grant requirements Be sure not only to
respond to the requirement but also to demonstrate your research
competence
1You must design a study that uses two different methods
(interviewobservation survey experiment or quasi-experiment) Describe your
two methods in detail and provide a rationale for the key elements (eg
sampling data collection proposed analysis) of your methods Be sure to
discuss and evaluate the internal and external validity of both methods
2 As part of your research design you must select a conceptual (latent) variable
central to your proposal (use centralization of decision making as your
variable) and describe how you will develop your own measure (You may not
simply use off the shelf instruments)
3 You must describe how you will test for the reliability of the measure
(centralization of decision making) you developed in step 2 The NSF insists
that you describe how you will evaluate both the temporal stability and the
internal consistency of your measure Be sure to discuss what temporal stability
and internal reliability mean and how they are related
4You must describe how you will assess the validity of the measure
(centralization of decision making) you developed in step 2
5 NSF requires a brief statement and defense of the philosophy of science
underlying your research Discuss your position and show how your research
design is consistent with your philosophy
B12 Many organizations in the United States economy have installed some form of
Empowered Teams as an alternative or supplement to traditional bureaucratic
structure Preliminary evidence of the effectiveness of empowered teams
however is mixed--some organizations have claimed success and others have
reported failures The evidence however is predominantly anecdotal--written
for trade magazines by the organizations themselves There are few rigorous
empirical studies assessing the effectiveness of empowered or self-managed
teams You are applying to the United States Department of Labor (USDOL) for
a grant to conduct research that examines the effectiveness of empowered
teams The application procedure of the USDOL imposes three requirements
that your research design must fulfill in order to receive funding Write your
response to each of the three grant requirements The importance of each section
is implied by the evaluation points allocated by the USDOL to each of the three
requirements given in parentheses
1 (50 points) Your study design for assessing Empowered Team effectiveness
must use two different methods (interview observation archival analysis
survey simulation experiment or quasi-experiment) Describe in detail and
thoroughly explain the sampling plan instrumentation data collection
procedures and proposed data analyses for both methods Be sure to discuss the
internal and external validity of both methods and how the two methods
complement one another
2 (30 points) As part of your research design you must select one conceptual
(latent) variable central to your proposal and describe how you will develop
your own operationalization of the measure (You may not simply use off the
shelf instruments) Use the concept of group morale to demonstrate your
operationalization methodology Be sure to explain very explicitly to the
USDOL how you will assess the validity and reliability of the group morale
measure you are developing
3 (20 points) The USDOL traditionally has funded research conducted only
within the general paradigm of logical positivism but now is more open to other
research paradigms as well Your grant proposal must provide a statement and
defense of the explicit philosophy of science underlying your research Describe
your philosophy of science and show how your research design is consistent
with your philosophy
REMEMBER Be thorough You not only must design effective research but
you also must demonstrate to the USDOL that you are a competent researcher
It is absolutely vital to the USDOL that the principal researcher is
knowledgeable about the proposed research methodologies Therefore be sure
that you always carefully describe and give technical explanations for each
component of your research design and explain all technical terms (eg
Cronbach alpha KR-20 Likert scale)
B13 Assume that you are working as part of a research team that is responding to a
RFP (Request for Proposals) from a funding agency for research on work
socialization and newcomer adjustment The RFP calls for rigorous field
research that tests the effectiveness of theory-based interventions aimed at
facilitating the adjustment of new organizational members to complex andor
stressful work conditions The major goal of your teams research is to test the
effectiveness of a self-regulation intervention which trains newcomers to
identify and use relevant social information and cues to regulate work behavior
Your group hypothesizes that self-regulation training will be more effective
than other common treatments or interventions (eg realistic job previews
institutionalized socialization tactics)
You have been included in the team because of your methodological expertise
Your role is to design a rigorous field experiment or quasi-experiment to test he
effectiveness of the self-regulation training program REMEMBER THE
MAJOR CRITERION FOR FUNDING IS THE RIGOR OF THE RESEARCH
DESIGN Design a field study to include in the grant proposal Your proposal
should contain the following two sections
1 Study Design Construct and describe in detail an experimental or quasi-
experimental design to test the effectiveness of your intervention Describe in
detail the experimental groups (including how they will be constructed) the
research setting the sampling plan for study participants the treatment
manipulation and the data collection procedures Also indicate any control or
nuisance variables that may be measured
After describing the procedures write a justification of the design What threats
to validity does it rule out or limit and what threats to validity remain
II Measurement Describe the steps you would take to achieve valid and
reliable measure of the latent (conceptual) variable worker adjustment Your
team feels that as part of the proposal you must develop an original
operationalization of adjustment (thus you cannot simply use existing off the
shelf measures) Indicate in adequate detail how you would operationalize the
measure and indicate how you would demonstrate reliability and validity
B14 In describing their notion of the collective mind Karl E Weick and Karlene H
Roberts note Our focus is at once on individuals and the collective since only
individuals can contribute to a collective mind but a collective mind is distinct
from an individual because it inheres in the pattern of interrelated activities
among many people (p 360) Collective mind is not indexed by within-group
similarity of attitudes ideas or activities A collective mind is one in which
many people or many groups integrate their different attitudes ideas and
activities heedfully As Weick and Roberts note People act heedfully when
they act more or less carefully critically consistently purposefully attentively
studiously vigilantly conscientiously pertinaciously (p 361)
The idea of the collective mind as heedful interrelating is developed in the
following excerpt When people make efforts to interrelate these efforts can
range from heedful to heedless The more heed reflected in a pattern of
interrelations the more developed the collective mind and the greater the
capability to comprehend unexpected events that evolve rapidly in unexpected
ways When we say that a collective mind comprehends unexpected events we
mean that heedful interrelating connects sufficient know-how to meet situational
demands For organizations concerned with reliability those developments
often consist of unexpected non-sequential interaction (p366)
An example of heedful interrelating occurs as a pilot lands herhis aircraft on the
deck of an aircraft carrier The pilot does not actually land She is recovered
A recovery is an interrelated set of activities among air traffic controllers
landing signal officers the control tower navigators deck hands the helmsman
driving the ship etc These activities can be interrelated more or less heedfully
depending on the care with which the different units contribute represent the
situation and subordinate their activities to the single purpose of successful
recovery (p 363)
You are to design a two-part study
Part I You are to design a measurement study which assesses heedful
interrelating (ie collective mind) with a quantitative measure in a replication
of an aircraft carrier flight deck or other situation of your choosing Describe
your research strategies including operationalization of the variable selection of
the sample subjects data collection data analysis and so on for the purpose of
developing a measure of heedful interrelating
Part II Using the measurement tool developed in Part I and any other tools as
needed describe how you would design a study which would compare heedful
interrelating across organizations Choose at least one macro-organizational
variable (eg technology environment) as your basis of comparison Here you
must describe how you would make your selection of organizations to be
compared your data collection procedure data analysis and so on
B15 Many organizations in the United States have installed cross-functional teams to
counteract the silo mentality of traditional bureaucratic structure Preliminary
evidence of the effectiveness of cross-functional teams however is mixed --
some organizations have claimed success and others have reported failures The
evidence moreover is predominantly anecdotal--written for trade magazines by
the organizations themselves Since there have been few rigorous empirical
field studies assessing the effectiveness of cross functional teams the National
Science Foundation has decided to fund research on the topic
Assume that you are submitting a research proposal to NSF for a grant to
research the effectiveness of cross-functional teams Describe in detail and
thoroughly explain the research design sampling plan data collection
procedures ethical issues and proposed data analysis for your research design
Be sure to discuss the internal and external validity of your research Which
validity threats are ruled out and which remain NSF also requires that you
provide a statement and defense of the explicit philosophy of science underlying
your research Describe your philosophy of science and discuss how your
research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but
you must also demonstrate to NSF that you are a competent researcher It is
absolutely vital to NSF that the principal researcher (you) is knowledgeable
about the proposed research methodologies Therefore be sure that you always
carefully describe and give technical explanations for each component of your
research design and explain all technical terms (eg Cronbach alpha KR-20
Likert scale)
B16 Assume that you are submitting a research proposal to the Department of
Commerce (DoC) for a grant to research the effectiveness of virtual work teams
A virtual work team is a leaderless collection of individuals who are
geographically separate from one another and share their expertise using
internet media such as a listserver or Lotus notes The DoC requires that the
researcher use both qualitative and quantitative methods to gather data Describe
in detail and thoroughly explain the research design sampling plan data
collection procedures ethical issues and proposed data analysis for your
research design Be sure to discuss the internal and external validity of your
research Which validity threats are ruled out and which remain The DoC also
requires that you provide a statement and defense of the explicit philosophy of
science underlying your research Describe your philosophy of science and
discuss how your research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but
you must also demonstrate to DoC that you are a competent researcher It is
absolutely vital to DoC that the principal investigator (you) is knowledgeable
about the proposed research methodologies Therefore be sure that you always
carefully describe and give technical explanations for each component of your
research

5 MEASUREMENT
A) Measurement Terms
A1 There are four levels of measurement rigor in management research Discuss each
one What properties do measurements at each level have (ie how much
information do the numbers from each level of measurement convey) How can the
numbers be changed (transformed) and still retain the properties of their
measurement level Pick one construct from a favorite research domain and give an
example of an operationalization of that construct at each of the four levels of
measurement rigor (provide arguments about why you think those examples reflect
each level) Lastly treat each examplelevel as a dependent variable in some
statistical analysis Given an example of a statistical technique appropriate for
analyzing data at that level of measurement rigor
A2 Define (and discuss important features or issues concerning) the following
constructs measurement (Define any six terms)
1 Construct validity 6 Item analysis
2 Likert scaling 7 Semantic differential
3 Cronbachs alpha 8 True score
4 Unobtrusive (trace) measurement 9 Generalizability theory
5 Interval scale 10 Criterion-related validity
11 Sociometric choice measures
B) Operationalization
B1 a) You are conducting a study which requires you to measure Hong Kong real
estate agents self-assessment of performance Since there is no existing
measurement available you have to develop the instrument by yourself
Describe how you would develop the measurement assuming that you have no
idea of how many dimension the construct has
b) Suppose you have developed an instrument consists of 20 questions
measuring 4 dimensions (5 items per dimension) from (a) You collected data
from another 300 real estate agents to validate your instrument Explain how
TH
you would use structural equations model (SEM) to examine the reliability and
validity of the instrument What are other concerns about reliability and validity
that are not addressed by this approach
B2 The research and business world have been fascinated with the concept of
organizational culture However operationalizing this construct has been a
difficult task Discuss the ways in which the construct has been operationalized
(eg technique static v dynamic sample selection generalizability) Critically
analyze each of these methodologies Then choose a methodology you would
use to examine organizational culture and defend your choice Describe how
you would study culture and what more would be known about culture as a
result of your study
B3 Suppose you are setting out to develop a new measure of a construct You want
this measure to be used in survey research and you want to establish its validity
and reliability Your goal is to have at the end of the process a measure that is

found very interesting The authors argued that one of the predictors of
workplace violence was a construct called propensity to be violent and used a
one-item measure as follows How likely are you to become violent when
provoked You had serious doubts about the authors measure and decided to
develop your own

B6 A concern in organizations is retirement of baby boomers within the next 5 -
10 years This concern is focused on the loss of older employees with skills
critical to the core business functions of organizations In order to continue to
have employees with those critical skills it seems necessary to retrain some
older workers However past practice in most organizations has been not to
retrain older workers for a variety of reasons mostly financial A researcher
working for the Human Resources Department of a large corporation - 13500
employees in 12 different plant locations - hypothesizes that the major reason
for not retraining older workers is ingrained in the culture of the corporation
IC
The researcher feels that older workers are not as highly valued as younger
workers in terms of their potential usefulness after retraining The researcher
searched the literature but found nothing in the existing literature to measure
the cultural value construct What should the researcher do to establish a reliable
and valid self-administered paper and pencil measure of this construct namely
the value of retraining older workers

archival measures direct observation and trace measures) for measuring
organizational effectiveness Next describe and justify the steps you would
take to develop an operationalization of the concept of organizational
effectiveness What standards and procedures would you use to determine if
your operationalization is valid
B9 One of the most important topics of recent research has been stress in the work
place One of the most important problems with understanding this literature is

development to delineate 2 dimensions of X specifically XF1 and XF2
Describe the steps you would go through in developing testing and evaluating
this new scale With regard to testing and evaluating be sure to consider the
role of factor analysis (both exploratory and confirmatory) and item analysis
Also you will want to make sure that your new multidimensional scale shows
evidence of validity (several kinds) and reliability so be sure to examine these

number of test items and sample size on Chronbachs alpha and why would this
effect occur or not occur (Note Do NOT discuss inter-rater reliability)
C10 Schmidt and Hunter (1996) described several types of measures typically used in
organizational research and identified the type(s) of measurement error affecting
each of them in various situations For each measure below indicate the types of
error and sources of error that are most likely to affect it Then indicate what

C11 Suppose you had conducted research on the relationship between organizational
commitment and rigidity of organizational structure in 200 firms Your measure
of rigidity was based on number of organizational authority levels and the degree
to which written organizational rules existed and defined role behaviors for
employees Thus an organization with a large number of organizational levels
and specific written policies defining appropriate role behaviors for employees
would score high on rigidity of organizational structure After analyzing your
data you find that there is a statistically significant negative correlation between
commitment and rigidity which is consistent with your hypothesis However the
reliabilities for your two measures are
(1) commitment = 23 (2) rigidity = 83
How should you interpret your results What could you do to fix this situation

Organizational climate is operationalized as a shared consensual aspect of the
organization -- the shared perception among employees that the organization values
and supports continuous learning Describe how you would measure organizational
climate in this case Specify (a) the level (ie individual group organization) at
which the construct exists (b) the level at which you would measure the construct
and (c) the procedures that you would use to establish that measurement is aligned
with theory (ie the construct validity of the measure)
E) General (Measurement)
E1 Studies in organizational behavior research often rely on single-item measures of
key constructs The use of single-item measures has long been criticized based
on the premise that single-item measures are unreliable However Wanous
(Wanous amp Hudy 2001 Wanous amp Reichers 1996 Wanous Reichers amp Hudy
1997) has recently argued that single-item measures can exhibit adequate
reliability Wanous based this conclusion on a procedure for estimating the
reliability of single-item measures using the classic formula for correction for
attenuation Subsequent studies have yielded mixed results regarding the
conclusions of Wanous (eg Loo amp Kells 1998 Nagy 2002) and the veracity
of the perspective advocated by Wanous remains in question Summarize and
assess the arguments for and against the use of single-item measures and
evaluate the procedure and evidence offered by Wanous regarding the reliability
of single-item measures Based on your assessment and evaluation develop
recommendations regarding the use of single-item measures in organizational
behavior research

E2 Ipsative measures have become prevalent in organizational behavior research
Ipsative measures ask respondents to answer questions relative to one another
such that the scores for all questions sum to the same constant for all respondents
Examples of ipsative measures include rankings Q-sorts and the allocation of a
fixed number of points (eg 100) across a set of response options Ipsative
measures may be contrasted with absolute measures which ask respondents to
answer questions independently from one another Absolute measures are
exemplified by rating scales using an interval or ratio numeric response format
The relative merits of ipsative and absolute measures have been debated for
decades (eg Cornwell amp Dunlap 1994 Hicks 1970 Johnson Wood amp
Blinkhorn 1988 Saville amp Wilson 1991 1992) yet the fundamental issues
underlying this debate have not been adequately addressed in organizational
behavior research For example measures of organizational culture and values
are often ipsative and some researchers advocate these measures over absolute
measures (eg Meglino amp Ravlin 1987 OReilly Chatman amp Caldwell 1991
Ravlin amp Meglino 1987 see also Rokeach amp Ball-Rokeach 1989) Review the
relative merits of absolute and ipsative measures Based on your review which
form of measurement is most appropriate and why Do your conclusions depend
on the construct being measured If so what types of constructs are best suited to
ipsative measures and what types are best suited to absolute measures Next
apply your conclusions to the measurement of culture and values in
organizations What specific arguments have been advanced in favor of ipsative
measures of culture and values How sound are these arguments Should ipsative
measures be used in the study of organizational culture and values If not how
can absolute measures of culture and values be developed that address the
concerns voiced by advocates of ipsative measures Provide a specific example

facets of a concept Although such measures are prevalent and in some cases are

E5 Suppose Roberta Von Eisenbrick is a researcher interested in the consequences of
AFFECTIVE CONFLICT (AC) in decision-making teams She gets access to a
variety of outcomes assessment committees at each of 87 different schools in
the Dallas Independent School District and gains permission to tape-record two
of their meetings (one in February and one in March) Such committees have
been formed to develop quantitative ways to track pursuit of school goals and
provide accountability to local and state governments These are often divisive
teams with heated meetings because what gets assessed is what usually gets
rewarded After both of these meetings the committee members each
fill out a short questionnaire that contains 20 Likert-type items measuring how
much AC occurred (eg People in our group often get angry with each other)
The individual scores are summed across items then averaged across team
members to come up with a group-level AC score for each of the 87 2
meetings The same procedures are followed for a 5-item measure of Group
Cohesiveness (GC) which is predicted to be reduced by higher levels of AC
Roberta also listens to every tape and from her expert judgment she rates each
groups meetings on the same 20 items Those 20 ratings are summed for each of
the 87 2 meetings Now Roberta is interested in evaluating her measure She
wants it to have excellent psychometric properties including reliability and
construct validity

(a) Please define both of these terms (b) Sketch a conceptual model to show how
each relates to main effects (c) Using variables of your choice please write
hypotheses to reflect both (d) Explain how each is tested analytically
D2 Discuss moderators and mediators Provide an example of how (1) a moderating
variable influences the relationship between the independent and dependent
variable and how (2) a mediating variable influences the relationship between
the independent and dependent variable Describe how you would test for both
moderation and mediation using regression
D3 Many theories in organizational research predict that the effects of one variable
on another are moderated by a third variable Such moderator effects are
typically tested by entering the product of two variables as a predictor after
controlling for the two variables that constitute the product Several researchers
have pointed out that this product is often highly correlated with the squares of
the two constituent variables and have suggested that moderating effects may be
tested after controlling not only for the two constituent variables but also their
squares (eg Cortina 1993 Ganzach 1998 Lubinski amp Humphreys 1990
MacCallum amp Mar 1995) Discuss the strengths and weaknesses of this
approach as compared to methods that use only the product term and its
constituent variables Conclude with recommendations as to when and under
what conditions organizational researchers should test moderator effects with the
squares of the constituent variables in the equation

D4 Assume you are interested in studying relationships amongst three variables X
Y and Z Your first hypothesis posits Z as a mediator of the relationship between
X and Y Your second hypothesis posits Z as a moderator of the relationship
between X and Y Draw the figures depicting each of these hypothesized
relationships and describe (make sure to write regression equations) how you
would test each of these hypotheses
D5 The amount of time and effort that the average person pours into his or her job
has risen steadily over the last two decades such that the average person now is
working one more week per year than the average person in the mid 1970s This
steady increase has fueled research interest in the construct of Job Burnout (JB)
which is an emotional and physical exhaustion associated with ones work
Organizational Stress (OS) the perception of greater demands than available
resources in ones work environment is thought to be one of the chief
antecedents of JB However time spent under OS is thought to make its affects
on JB accumulate or worsen Work Role Withdrawal (WRW) the avoidance of
responsibilities or the deliberate reduction of inputs to ones job is believed to be
the chief consequence of JB
a Formally state these ideas as verbal hypotheses as equations and as a complex
directed graph (circle amp arrow diagram)
b Conceptually what is a mediator Define the term and identify the mediator in
your hypotheses in (a) What elements or steps in a study design (not statistics)
that would be helpful for detecting the mediating relationship that was proposed

subdomains of management Further demonstrate your understanding of
moderator variables by picking which variable in (a) is the moderator Show the
moderating relationship in an X-Y (or multi-layered) chart Again what elements
or steps in a study design (not statistics) would be helpful for detecting the
moderating effect implied above

reader understand the results of the statistical tests you report and the nature of your
sample (Hint this can be presented in the form of a table)
2 describing and defending your choice of appropriate statistical tests of the
hypotheses and the steps that you would go through in carrying out these tests
3 making up and reporting results of these tests that are consistent with your
descriptive statistics and with any information in the rest of the article about the
results found (Hint this can be presented in the form of a table)

may want to note any relevant threats to validity here
Be sure to state any assumptions you make
F2 Assume that the Personnel Manager of a local firm Ms B dFlandres hired you to
analyze some data that her assistants had collected over the past several years The
data consist of (a) job performance ratings that were made in June of 1990 and (b)
scores on 25 predictor variables (eg measures of education job experience job
tenure job aptitude personality) that were measured when the individuals were hired
(between April 1987 and May 1988) She had data from only the 110 subjects (60
males and 50 females) who were hired during the period and were still employed by
the firm One objective of your analysis (analyses) is to determine how well the
performance criterion can be predicted by the predictors What strategy would you
use in analyzing the data Describeexplain (b) Is sample size an issue for your
analyses Explain If it is what will you do to deal with problems stemming from
sample size Assume that no additional data can be collected at this time (c) Some
preliminary analyses that you do reveal that five of the predictor variables correlate
(zero-order basis) about 75 with one another Will this influence the analyses that
you use Will it influence the validity of conclusions derived from your proposed
analyses (d) Ms dFlandres is interested in knowing if the predictor variables are
equally effective in predicting the job success of males and females What analysis
or analyses would you do to deal with this issue
F3 Assume that you have been provided with data on 12 conceptually distinct variables
that are moderately correlated with one another at the empirical level The data are
from students in four different college majors ie astronomy (A) biology (B)
criminology (C) and demography (D) The 12 measured variables fall into the
general categories of mental health (tension emotional withdrawal hallucinations
guilt feelings blunted affect and suspiciousness) and job satisfaction (work itself
supervision co-workers pay promotion prospects and working conditions) Your
task is to determine if the individuals in the four college majors differ from one
another on the 12 measured variables

groups differ from one another Be specific
F4 The following statistical table published in a recent issue of Work amp Occupations
was taken from an article discussing variables influencing resistance and citizenship
behaviors in the workplace Resistance behaviors include playing dumb withholding
effort work avoidance subverting particular managers and sabotage Citizenship
behaviors include cooperation engaging in peer training use of insider knowledge to
facilitate production commitment to organizational goals giving extra effort freely
Both measures are global constructs aggregated to the interval level and
standardized
The table reports the results of a series of ordinary least squares regression equations
with standardized coefficients Explain the meaning of the statistics presented What
do these statistics tell us generally about the relationship between resistance
behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows
Anomie Index -standardized interval level measure tapping multiple dimensions
The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)

low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

interaction effect
I2 A study examined the effects of gender and pre-training motivation on the transfer of
training in terms of improved performance for 123 new industrial managers The
training was on supervisory skills and the dependent variable was based on the
appraisal of the supervisors performance before the training and three months after
the training The performance appraisal data were collected for research purposes
only and resulted in a total transfer score from 1 to 25 with 1 being low Pre-training
motivation was based on a 12 item Likert scale with an alpha of 86 Two groups
were identified for the pre-training motivation variable - the bottom 13 (low) and the
top 13 (high) Table 1 contains the ANOVA results and Table 2 contains the cell

particular care to enumerate the disadvantages associated with quantitative review
Then offer two ways that meta-analysis might be combined with other analytical
techniques to move beyond the focus of bivariate relationships that is typical of meta-
analysis

scientific laws but that meta-analytic research does What are the arguments in favor
of or against this position In what areas of research (if any) has Schmidts
prediction come closest to coming true

that a meta-analysis can make to theory building in the organizational sciences (c)
Describe the circumstances that you would consider when deciding whether to
perform a meta-analysis

mirrors Explain both sides of the debate and then lay out the role of meta-analysis
as you see it within the time span of your career as an academic To do this use
examples of already written (or yet to be written) articles as models
J5 A frequent criticism of non-quantitative research summaries (literature reviews) is
that researchers do not carefully examine how particular research designs might have
affected the statistical outcomes of the studies included in the literature review Meta-
analysis however allows one to statistically examine such effects Assume you are
conducting a meta-analysis of the relationship between leader behaviors and group
productivity Briefly describe the steps you would take in conducting a meta-
analysis What aspects of the original research designs would you examine in your
meta-analysis What steps would you take in gathering and coding data to enhance
the credibility of your analysis

O1 Contrast Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis
(CFA) Give an example for the appropriate use of each of the above analyses
What is the role of theory in the two factor analyses
IC

assumptions usage and limitations
O3 How do exploratory and confirmatory factor analysis differ What are the
advantages and disadvantages of each
O4 Describe the differences between exploratory factor analysis (EFA) and
confirmatory factor analysis (CFA) When would you use one verses another
Are there ways to use EFA in a confirmatory way Can you use CFA in an
exploratory way Also describe the difference in principal components analysis
(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression
O6 The basic factor analysis model can be represented by the matrix algebraic
equation A B = C
(1) What do each of these matrices represent Be specific as to the type of
information in each matrix and its purpose
(2) For what purpose do researchers use factor analysis Explain In the process
provide a very brief description of a study for which factor analysis would be a
useful data analytic technique
O7 Factor analysis is an important statistical technique in organizational research
Describe factor analysis as an analytical tool including the following issues
a the reasons for using factor analysis
b the type of data necessary for using the technique appropriately
c the type of quantitative output that results from applying the technique
d how a researcher would use the output in his or her research
e how confirmatory factor analysis is different from exploratory
f the important issues and problems in using the technique
P) Structural Equation Models
P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

parameter estimate bias in structural equation modeling Structural Equation

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)
Please comment on these restrictions versus access argument Which side do you
take
What are the strengths of SEM Give some examples
What are the weaknesses of SEM Give some examples

competence
1You must design a study that uses two different methods
(interviewobservation survey experiment or quasi-experiment) Describe your
two methods in detail and provide a rationale for the key elements (eg
sampling data collection proposed analysis) of your methods Be sure to
discuss and evaluate the internal and external validity of both methods
2 As part of your research design you must select a conceptual (latent) variable
central to your proposal (use centralization of decision making as your
variable) and describe how you will develop your own measure (You may not
simply use off the shelf instruments)
3 You must describe how you will test for the reliability of the measure
(centralization of decision making) you developed in step 2 The NSF insists
that you describe how you will evaluate both the temporal stability and the
internal consistency of your measure Be sure to discuss what temporal stability
and internal reliability mean and how they are related
4You must describe how you will assess the validity of the measure
(centralization of decision making) you developed in step 2
5 NSF requires a brief statement and defense of the philosophy of science
underlying your research Discuss your position and show how your research
design is consistent with your philosophy
B12 Many organizations in the United States economy have installed some form of
Empowered Teams as an alternative or supplement to traditional bureaucratic
structure Preliminary evidence of the effectiveness of empowered teams
however is mixed--some organizations have claimed success and others have
reported failures The evidence however is predominantly anecdotal--written
for trade magazines by the organizations themselves There are few rigorous
empirical studies assessing the effectiveness of empowered or self-managed
teams You are applying to the United States Department of Labor (USDOL) for
a grant to conduct research that examines the effectiveness of empowered
teams The application procedure of the USDOL imposes three requirements
that your research design must fulfill in order to receive funding Write your
response to each of the three grant requirements The importance of each section
is implied by the evaluation points allocated by the USDOL to each of the three
requirements given in parentheses
1 (50 points) Your study design for assessing Empowered Team effectiveness
must use two different methods (interview observation archival analysis
survey simulation experiment or quasi-experiment) Describe in detail and
thoroughly explain the sampling plan instrumentation data collection
procedures and proposed data analyses for both methods Be sure to discuss the
internal and external validity of both methods and how the two methods
complement one another
2 (30 points) As part of your research design you must select one conceptual
(latent) variable central to your proposal and describe how you will develop
your own operationalization of the measure (You may not simply use off the
shelf instruments) Use the concept of group morale to demonstrate your
operationalization methodology Be sure to explain very explicitly to the
USDOL how you will assess the validity and reliability of the group morale
measure you are developing
3 (20 points) The USDOL traditionally has funded research conducted only
within the general paradigm of logical positivism but now is more open to other
research paradigms as well Your grant proposal must provide a statement and
defense of the explicit philosophy of science underlying your research Describe
your philosophy of science and show how your research design is consistent
with your philosophy
REMEMBER Be thorough You not only must design effective research but
you also must demonstrate to the USDOL that you are a competent researcher
It is absolutely vital to the USDOL that the principal researcher is
knowledgeable about the proposed research methodologies Therefore be sure
that you always carefully describe and give technical explanations for each
component of your research design and explain all technical terms (eg
Cronbach alpha KR-20 Likert scale)
B13 Assume that you are working as part of a research team that is responding to a
RFP (Request for Proposals) from a funding agency for research on work
socialization and newcomer adjustment The RFP calls for rigorous field
research that tests the effectiveness of theory-based interventions aimed at
facilitating the adjustment of new organizational members to complex andor
stressful work conditions The major goal of your teams research is to test the
effectiveness of a self-regulation intervention which trains newcomers to
identify and use relevant social information and cues to regulate work behavior
Your group hypothesizes that self-regulation training will be more effective
than other common treatments or interventions (eg realistic job previews
institutionalized socialization tactics)
You have been included in the team because of your methodological expertise
Your role is to design a rigorous field experiment or quasi-experiment to test he
effectiveness of the self-regulation training program REMEMBER THE
MAJOR CRITERION FOR FUNDING IS THE RIGOR OF THE RESEARCH
DESIGN Design a field study to include in the grant proposal Your proposal
should contain the following two sections
1 Study Design Construct and describe in detail an experimental or quasi-
experimental design to test the effectiveness of your intervention Describe in
detail the experimental groups (including how they will be constructed) the
research setting the sampling plan for study participants the treatment
manipulation and the data collection procedures Also indicate any control or
nuisance variables that may be measured
After describing the procedures write a justification of the design What threats
to validity does it rule out or limit and what threats to validity remain
II Measurement Describe the steps you would take to achieve valid and
reliable measure of the latent (conceptual) variable worker adjustment Your
team feels that as part of the proposal you must develop an original
operationalization of adjustment (thus you cannot simply use existing off the
shelf measures) Indicate in adequate detail how you would operationalize the
measure and indicate how you would demonstrate reliability and validity
B14 In describing their notion of the collective mind Karl E Weick and Karlene H
Roberts note Our focus is at once on individuals and the collective since only
individuals can contribute to a collective mind but a collective mind is distinct
from an individual because it inheres in the pattern of interrelated activities
among many people (p 360) Collective mind is not indexed by within-group
similarity of attitudes ideas or activities A collective mind is one in which
many people or many groups integrate their different attitudes ideas and
activities heedfully As Weick and Roberts note People act heedfully when
they act more or less carefully critically consistently purposefully attentively
studiously vigilantly conscientiously pertinaciously (p 361)
The idea of the collective mind as heedful interrelating is developed in the
following excerpt When people make efforts to interrelate these efforts can
range from heedful to heedless The more heed reflected in a pattern of
interrelations the more developed the collective mind and the greater the
capability to comprehend unexpected events that evolve rapidly in unexpected
ways When we say that a collective mind comprehends unexpected events we
mean that heedful interrelating connects sufficient know-how to meet situational
demands For organizations concerned with reliability those developments
often consist of unexpected non-sequential interaction (p366)
An example of heedful interrelating occurs as a pilot lands herhis aircraft on the
deck of an aircraft carrier The pilot does not actually land She is recovered
A recovery is an interrelated set of activities among air traffic controllers
landing signal officers the control tower navigators deck hands the helmsman
driving the ship etc These activities can be interrelated more or less heedfully
depending on the care with which the different units contribute represent the
situation and subordinate their activities to the single purpose of successful
recovery (p 363)
You are to design a two-part study
Part I You are to design a measurement study which assesses heedful
interrelating (ie collective mind) with a quantitative measure in a replication
of an aircraft carrier flight deck or other situation of your choosing Describe
your research strategies including operationalization of the variable selection of
the sample subjects data collection data analysis and so on for the purpose of
developing a measure of heedful interrelating
Part II Using the measurement tool developed in Part I and any other tools as
needed describe how you would design a study which would compare heedful
interrelating across organizations Choose at least one macro-organizational
variable (eg technology environment) as your basis of comparison Here you
must describe how you would make your selection of organizations to be
compared your data collection procedure data analysis and so on
B15 Many organizations in the United States have installed cross-functional teams to
counteract the silo mentality of traditional bureaucratic structure Preliminary
evidence of the effectiveness of cross-functional teams however is mixed --
some organizations have claimed success and others have reported failures The
evidence moreover is predominantly anecdotal--written for trade magazines by
the organizations themselves Since there have been few rigorous empirical
field studies assessing the effectiveness of cross functional teams the National
Science Foundation has decided to fund research on the topic
Assume that you are submitting a research proposal to NSF for a grant to
research the effectiveness of cross-functional teams Describe in detail and
thoroughly explain the research design sampling plan data collection
procedures ethical issues and proposed data analysis for your research design
Be sure to discuss the internal and external validity of your research Which
validity threats are ruled out and which remain NSF also requires that you
provide a statement and defense of the explicit philosophy of science underlying
your research Describe your philosophy of science and discuss how your
research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but
you must also demonstrate to NSF that you are a competent researcher It is
absolutely vital to NSF that the principal researcher (you) is knowledgeable
about the proposed research methodologies Therefore be sure that you always
carefully describe and give technical explanations for each component of your
research design and explain all technical terms (eg Cronbach alpha KR-20
Likert scale)
B16 Assume that you are submitting a research proposal to the Department of
Commerce (DoC) for a grant to research the effectiveness of virtual work teams
A virtual work team is a leaderless collection of individuals who are
geographically separate from one another and share their expertise using
internet media such as a listserver or Lotus notes The DoC requires that the
researcher use both qualitative and quantitative methods to gather data Describe
in detail and thoroughly explain the research design sampling plan data
collection procedures ethical issues and proposed data analysis for your
research design Be sure to discuss the internal and external validity of your
research Which validity threats are ruled out and which remain The DoC also
requires that you provide a statement and defense of the explicit philosophy of
science underlying your research Describe your philosophy of science and
discuss how your research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but
you must also demonstrate to DoC that you are a competent researcher It is
absolutely vital to DoC that the principal investigator (you) is knowledgeable
about the proposed research methodologies Therefore be sure that you always
carefully describe and give technical explanations for each component of your
research

A) Measurement Terms
A1 There are four levels of measurement rigor in management research Discuss each
one What properties do measurements at each level have (ie how much
information do the numbers from each level of measurement convey) How can the
numbers be changed (transformed) and still retain the properties of their
measurement level Pick one construct from a favorite research domain and give an
example of an operationalization of that construct at each of the four levels of
measurement rigor (provide arguments about why you think those examples reflect
each level) Lastly treat each examplelevel as a dependent variable in some
statistical analysis Given an example of a statistical technique appropriate for
analyzing data at that level of measurement rigor

B6 A concern in organizations is retirement of baby boomers within the next 5 -
10 years This concern is focused on the loss of older employees with skills
critical to the core business functions of organizations In order to continue to
have employees with those critical skills it seems necessary to retrain some
older workers However past practice in most organizations has been not to
retrain older workers for a variety of reasons mostly financial A researcher
working for the Human Resources Department of a large corporation - 13500
employees in 12 different plant locations - hypothesizes that the major reason
for not retraining older workers is ingrained in the culture of the corporation
IC
The researcher feels that older workers are not as highly valued as younger
workers in terms of their potential usefulness after retraining The researcher
searched the literature but found nothing in the existing literature to measure
the cultural value construct What should the researcher do to establish a reliable
and valid self-administered paper and pencil measure of this construct namely
the value of retraining older workers

organizational effectiveness Next describe and justify the steps you would
take to develop an operationalization of the concept of organizational
effectiveness What standards and procedures would you use to determine if
your operationalization is valid
B9 One of the most important topics of recent research has been stress in the work

number of test items and sample size on Chronbachs alpha and why would this
effect occur or not occur (Note Do NOT discuss inter-rater reliability)
C10 Schmidt and Hunter (1996) described several types of measures typically used in
organizational research and identified the type(s) of measurement error affecting
each of them in various situations For each measure below indicate the types of
error and sources of error that are most likely to affect it Then indicate what

C11 Suppose you had conducted research on the relationship between organizational
commitment and rigidity of organizational structure in 200 firms Your measure
of rigidity was based on number of organizational authority levels and the degree
to which written organizational rules existed and defined role behaviors for
employees Thus an organization with a large number of organizational levels
and specific written policies defining appropriate role behaviors for employees
would score high on rigidity of organizational structure After analyzing your
data you find that there is a statistically significant negative correlation between
commitment and rigidity which is consistent with your hypothesis However the
reliabilities for your two measures are
(1) commitment = 23 (2) rigidity = 83
How should you interpret your results What could you do to fix this situation

and supports continuous learning Describe how you would measure organizational
climate in this case Specify (a) the level (ie individual group organization) at
which the construct exists (b) the level at which you would measure the construct
and (c) the procedures that you would use to establish that measurement is aligned
with theory (ie the construct validity of the measure)
E) General (Measurement)
E1 Studies in organizational behavior research often rely on single-item measures of
key constructs The use of single-item measures has long been criticized based
on the premise that single-item measures are unreliable However Wanous
(Wanous amp Hudy 2001 Wanous amp Reichers 1996 Wanous Reichers amp Hudy
1997) has recently argued that single-item measures can exhibit adequate
reliability Wanous based this conclusion on a procedure for estimating the
reliability of single-item measures using the classic formula for correction for
attenuation Subsequent studies have yielded mixed results regarding the
conclusions of Wanous (eg Loo amp Kells 1998 Nagy 2002) and the veracity
of the perspective advocated by Wanous remains in question Summarize and
assess the arguments for and against the use of single-item measures and
evaluate the procedure and evidence offered by Wanous regarding the reliability
of single-item measures Based on your assessment and evaluation develop
recommendations regarding the use of single-item measures in organizational
behavior research

E2 Ipsative measures have become prevalent in organizational behavior research
Ipsative measures ask respondents to answer questions relative to one another
such that the scores for all questions sum to the same constant for all respondents
Examples of ipsative measures include rankings Q-sorts and the allocation of a
fixed number of points (eg 100) across a set of response options Ipsative
measures may be contrasted with absolute measures which ask respondents to
answer questions independently from one another Absolute measures are
exemplified by rating scales using an interval or ratio numeric response format
The relative merits of ipsative and absolute measures have been debated for
decades (eg Cornwell amp Dunlap 1994 Hicks 1970 Johnson Wood amp
Blinkhorn 1988 Saville amp Wilson 1991 1992) yet the fundamental issues
underlying this debate have not been adequately addressed in organizational
behavior research For example measures of organizational culture and values
are often ipsative and some researchers advocate these measures over absolute
measures (eg Meglino amp Ravlin 1987 OReilly Chatman amp Caldwell 1991
Ravlin amp Meglino 1987 see also Rokeach amp Ball-Rokeach 1989) Review the
relative merits of absolute and ipsative measures Based on your review which
form of measurement is most appropriate and why Do your conclusions depend
on the construct being measured If so what types of constructs are best suited to
ipsative measures and what types are best suited to absolute measures Next
apply your conclusions to the measurement of culture and values in
organizations What specific arguments have been advanced in favor of ipsative
measures of culture and values How sound are these arguments Should ipsative
measures be used in the study of organizational culture and values If not how
can absolute measures of culture and values be developed that address the
concerns voiced by advocates of ipsative measures Provide a specific example

E5 Suppose Roberta Von Eisenbrick is a researcher interested in the consequences of
AFFECTIVE CONFLICT (AC) in decision-making teams She gets access to a
variety of outcomes assessment committees at each of 87 different schools in
the Dallas Independent School District and gains permission to tape-record two
of their meetings (one in February and one in March) Such committees have
been formed to develop quantitative ways to track pursuit of school goals and
provide accountability to local and state governments These are often divisive
teams with heated meetings because what gets assessed is what usually gets
rewarded After both of these meetings the committee members each
fill out a short questionnaire that contains 20 Likert-type items measuring how
much AC occurred (eg People in our group often get angry with each other)
The individual scores are summed across items then averaged across team
members to come up with a group-level AC score for each of the 87 2
meetings The same procedures are followed for a 5-item measure of Group
Cohesiveness (GC) which is predicted to be reduced by higher levels of AC
Roberta also listens to every tape and from her expert judgment she rates each
groups meetings on the same 20 items Those 20 ratings are summed for each of
the 87 2 meetings Now Roberta is interested in evaluating her measure She
wants it to have excellent psychometric properties including reliability and
construct validity

each relates to main effects (c) Using variables of your choice please write
hypotheses to reflect both (d) Explain how each is tested analytically
D2 Discuss moderators and mediators Provide an example of how (1) a moderating
variable influences the relationship between the independent and dependent
variable and how (2) a mediating variable influences the relationship between
the independent and dependent variable Describe how you would test for both
moderation and mediation using regression
D3 Many theories in organizational research predict that the effects of one variable
on another are moderated by a third variable Such moderator effects are
typically tested by entering the product of two variables as a predictor after
controlling for the two variables that constitute the product Several researchers
have pointed out that this product is often highly correlated with the squares of
the two constituent variables and have suggested that moderating effects may be
tested after controlling not only for the two constituent variables but also their
squares (eg Cortina 1993 Ganzach 1998 Lubinski amp Humphreys 1990
MacCallum amp Mar 1995) Discuss the strengths and weaknesses of this
approach as compared to methods that use only the product term and its
constituent variables Conclude with recommendations as to when and under
what conditions organizational researchers should test moderator effects with the
squares of the constituent variables in the equation

D4 Assume you are interested in studying relationships amongst three variables X
Y and Z Your first hypothesis posits Z as a mediator of the relationship between
X and Y Your second hypothesis posits Z as a moderator of the relationship
between X and Y Draw the figures depicting each of these hypothesized
relationships and describe (make sure to write regression equations) how you
would test each of these hypotheses
D5 The amount of time and effort that the average person pours into his or her job
has risen steadily over the last two decades such that the average person now is
working one more week per year than the average person in the mid 1970s This
steady increase has fueled research interest in the construct of Job Burnout (JB)
which is an emotional and physical exhaustion associated with ones work
Organizational Stress (OS) the perception of greater demands than available
resources in ones work environment is thought to be one of the chief
antecedents of JB However time spent under OS is thought to make its affects
on JB accumulate or worsen Work Role Withdrawal (WRW) the avoidance of
responsibilities or the deliberate reduction of inputs to ones job is believed to be
the chief consequence of JB
a Formally state these ideas as verbal hypotheses as equations and as a complex
directed graph (circle amp arrow diagram)
b Conceptually what is a mediator Define the term and identify the mediator in
your hypotheses in (a) What elements or steps in a study design (not statistics)
that would be helpful for detecting the mediating relationship that was proposed

subdomains of management Further demonstrate your understanding of
moderator variables by picking which variable in (a) is the moderator Show the
moderating relationship in an X-Y (or multi-layered) chart Again what elements
or steps in a study design (not statistics) would be helpful for detecting the
moderating effect implied above

behaviors in the workplace Resistance behaviors include playing dumb withholding
effort work avoidance subverting particular managers and sabotage Citizenship
behaviors include cooperation engaging in peer training use of insider knowledge to
facilitate production commitment to organizational goals giving extra effort freely
Both measures are global constructs aggregated to the interval level and
standardized
The table reports the results of a series of ordinary least squares regression equations
with standardized coefficients Explain the meaning of the statistics presented What
do these statistics tell us generally about the relationship between resistance
behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows
Anomie Index -standardized interval level measure tapping multiple dimensions
The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)
F5 Researchers collected data from a sample of 350 companies on the following
variables
size (measured as number of employees)
Business Strategy (a nominal variable with 2 response options low-cost provider or
differentiator)
HR Strategy (a nominal variable with 2 response categories High commitment or
low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

I2 A study examined the effects of gender and pre-training motivation on the transfer of
training in terms of improved performance for 123 new industrial managers The
training was on supervisory skills and the dependent variable was based on the
appraisal of the supervisors performance before the training and three months after
the training The performance appraisal data were collected for research purposes
only and resulted in a total transfer score from 1 to 25 with 1 being low Pre-training
motivation was based on a 12 item Likert scale with an alpha of 86 Two groups

mirrors Explain both sides of the debate and then lay out the role of meta-analysis
as you see it within the time span of your career as an academic To do this use
examples of already written (or yet to be written) articles as models
J5 A frequent criticism of non-quantitative research summaries (literature reviews) is
that researchers do not carefully examine how particular research designs might have
affected the statistical outcomes of the studies included in the literature review Meta-
analysis however allows one to statistically examine such effects Assume you are
conducting a meta-analysis of the relationship between leader behaviors and group
productivity Briefly describe the steps you would take in conducting a meta-
analysis What aspects of the original research designs would you examine in your
meta-analysis What steps would you take in gathering and coding data to enhance
the credibility of your analysis

and discuss the assumptions of the general linear model Multiple regression
ANOVA and principle components (factor) analysis are based on the general linear
model For each of those three statistical procedures describe and discuss the
following

assumptions usage and limitations
O3 How do exploratory and confirmatory factor analysis differ What are the
advantages and disadvantages of each
O4 Describe the differences between exploratory factor analysis (EFA) and
confirmatory factor analysis (CFA) When would you use one verses another
Are there ways to use EFA in a confirmatory way Can you use CFA in an
exploratory way Also describe the difference in principal components analysis
(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression
O6 The basic factor analysis model can be represented by the matrix algebraic
equation A B = C

information in each matrix and its purpose
(2) For what purpose do researchers use factor analysis Explain In the process
provide a very brief description of a study for which factor analysis would be a
useful data analytic technique
O7 Factor analysis is an important statistical technique in organizational research
Describe factor analysis as an analytical tool including the following issues

b the type of data necessary for using the technique appropriately
c the type of quantitative output that results from applying the technique
d how a researcher would use the output in his or her research
e how confirmatory factor analysis is different from exploratory
f the important issues and problems in using the technique
P) Structural Equation Models
P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

parameter estimate bias in structural equation modeling Structural Equation

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)
Please comment on these restrictions versus access argument Which side do you
take
What are the strengths of SEM Give some examples
What are the weaknesses of SEM Give some examples

complement one another
2 (30 points) As part of your research design you must select one conceptual
(latent) variable central to your proposal and describe how you will develop
your own operationalization of the measure (You may not simply use off the
shelf instruments) Use the concept of group morale to demonstrate your
operationalization methodology Be sure to explain very explicitly to the
USDOL how you will assess the validity and reliability of the group morale
measure you are developing
3 (20 points) The USDOL traditionally has funded research conducted only
within the general paradigm of logical positivism but now is more open to other
research paradigms as well Your grant proposal must provide a statement and
defense of the explicit philosophy of science underlying your research Describe
your philosophy of science and show how your research design is consistent
with your philosophy
REMEMBER Be thorough You not only must design effective research but
you also must demonstrate to the USDOL that you are a competent researcher
It is absolutely vital to the USDOL that the principal researcher is
knowledgeable about the proposed research methodologies Therefore be sure
that you always carefully describe and give technical explanations for each
component of your research design and explain all technical terms (eg
Cronbach alpha KR-20 Likert scale)
B13 Assume that you are working as part of a research team that is responding to a
RFP (Request for Proposals) from a funding agency for research on work
socialization and newcomer adjustment The RFP calls for rigorous field
research that tests the effectiveness of theory-based interventions aimed at
facilitating the adjustment of new organizational members to complex andor
stressful work conditions The major goal of your teams research is to test the
effectiveness of a self-regulation intervention which trains newcomers to
identify and use relevant social information and cues to regulate work behavior
Your group hypothesizes that self-regulation training will be more effective
than other common treatments or interventions (eg realistic job previews
institutionalized socialization tactics)
You have been included in the team because of your methodological expertise
Your role is to design a rigorous field experiment or quasi-experiment to test he
effectiveness of the self-regulation training program REMEMBER THE
MAJOR CRITERION FOR FUNDING IS THE RIGOR OF THE RESEARCH
DESIGN Design a field study to include in the grant proposal Your proposal
should contain the following two sections
1 Study Design Construct and describe in detail an experimental or quasi-
experimental design to test the effectiveness of your intervention Describe in
detail the experimental groups (including how they will be constructed) the
research setting the sampling plan for study participants the treatment
manipulation and the data collection procedures Also indicate any control or
nuisance variables that may be measured
After describing the procedures write a justification of the design What threats
to validity does it rule out or limit and what threats to validity remain
II Measurement Describe the steps you would take to achieve valid and
reliable measure of the latent (conceptual) variable worker adjustment Your
team feels that as part of the proposal you must develop an original
operationalization of adjustment (thus you cannot simply use existing off the
shelf measures) Indicate in adequate detail how you would operationalize the
measure and indicate how you would demonstrate reliability and validity
B14 In describing their notion of the collective mind Karl E Weick and Karlene H
Roberts note Our focus is at once on individuals and the collective since only
individuals can contribute to a collective mind but a collective mind is distinct
from an individual because it inheres in the pattern of interrelated activities
among many people (p 360) Collective mind is not indexed by within-group
similarity of attitudes ideas or activities A collective mind is one in which
many people or many groups integrate their different attitudes ideas and
activities heedfully As Weick and Roberts note People act heedfully when
they act more or less carefully critically consistently purposefully attentively
studiously vigilantly conscientiously pertinaciously (p 361)
The idea of the collective mind as heedful interrelating is developed in the
following excerpt When people make efforts to interrelate these efforts can
range from heedful to heedless The more heed reflected in a pattern of
interrelations the more developed the collective mind and the greater the
capability to comprehend unexpected events that evolve rapidly in unexpected
ways When we say that a collective mind comprehends unexpected events we
mean that heedful interrelating connects sufficient know-how to meet situational
demands For organizations concerned with reliability those developments
often consist of unexpected non-sequential interaction (p366)
An example of heedful interrelating occurs as a pilot lands herhis aircraft on the
deck of an aircraft carrier The pilot does not actually land She is recovered
A recovery is an interrelated set of activities among air traffic controllers
landing signal officers the control tower navigators deck hands the helmsman
driving the ship etc These activities can be interrelated more or less heedfully
depending on the care with which the different units contribute represent the
situation and subordinate their activities to the single purpose of successful
recovery (p 363)
You are to design a two-part study
Part I You are to design a measurement study which assesses heedful
interrelating (ie collective mind) with a quantitative measure in a replication
of an aircraft carrier flight deck or other situation of your choosing Describe
your research strategies including operationalization of the variable selection of
the sample subjects data collection data analysis and so on for the purpose of
developing a measure of heedful interrelating
Part II Using the measurement tool developed in Part I and any other tools as
needed describe how you would design a study which would compare heedful
interrelating across organizations Choose at least one macro-organizational
variable (eg technology environment) as your basis of comparison Here you
must describe how you would make your selection of organizations to be
compared your data collection procedure data analysis and so on
B15 Many organizations in the United States have installed cross-functional teams to
counteract the silo mentality of traditional bureaucratic structure Preliminary
evidence of the effectiveness of cross-functional teams however is mixed --
some organizations have claimed success and others have reported failures The
evidence moreover is predominantly anecdotal--written for trade magazines by
the organizations themselves Since there have been few rigorous empirical
field studies assessing the effectiveness of cross functional teams the National
Science Foundation has decided to fund research on the topic
Assume that you are submitting a research proposal to NSF for a grant to
research the effectiveness of cross-functional teams Describe in detail and
thoroughly explain the research design sampling plan data collection
procedures ethical issues and proposed data analysis for your research design
Be sure to discuss the internal and external validity of your research Which
validity threats are ruled out and which remain NSF also requires that you
provide a statement and defense of the explicit philosophy of science underlying
your research Describe your philosophy of science and discuss how your
research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but
you must also demonstrate to NSF that you are a competent researcher It is
absolutely vital to NSF that the principal researcher (you) is knowledgeable
about the proposed research methodologies Therefore be sure that you always
carefully describe and give technical explanations for each component of your
research design and explain all technical terms (eg Cronbach alpha KR-20
Likert scale)
B16 Assume that you are submitting a research proposal to the Department of
Commerce (DoC) for a grant to research the effectiveness of virtual work teams
A virtual work team is a leaderless collection of individuals who are
geographically separate from one another and share their expertise using
internet media such as a listserver or Lotus notes The DoC requires that the
researcher use both qualitative and quantitative methods to gather data Describe
in detail and thoroughly explain the research design sampling plan data
collection procedures ethical issues and proposed data analysis for your
research design Be sure to discuss the internal and external validity of your
research Which validity threats are ruled out and which remain The DoC also
requires that you provide a statement and defense of the explicit philosophy of
science underlying your research Describe your philosophy of science and
discuss how your research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but
you must also demonstrate to DoC that you are a competent researcher It is
absolutely vital to DoC that the principal investigator (you) is knowledgeable
about the proposed research methodologies Therefore be sure that you always
carefully describe and give technical explanations for each component of your
research

B6 A concern in organizations is retirement of baby boomers within the next 5 -
10 years This concern is focused on the loss of older employees with skills
critical to the core business functions of organizations In order to continue to
have employees with those critical skills it seems necessary to retrain some
older workers However past practice in most organizations has been not to
retrain older workers for a variety of reasons mostly financial A researcher
working for the Human Resources Department of a large corporation - 13500
employees in 12 different plant locations - hypothesizes that the major reason
for not retraining older workers is ingrained in the culture of the corporation
IC
The researcher feels that older workers are not as highly valued as younger
workers in terms of their potential usefulness after retraining The researcher
searched the literature but found nothing in the existing literature to measure
the cultural value construct What should the researcher do to establish a reliable
and valid self-administered paper and pencil measure of this construct namely
the value of retraining older workers

take to develop an operationalization of the concept of organizational
effectiveness What standards and procedures would you use to determine if
your operationalization is valid
B9 One of the most important topics of recent research has been stress in the work

number of test items and sample size on Chronbachs alpha and why would this
effect occur or not occur (Note Do NOT discuss inter-rater reliability)
C10 Schmidt and Hunter (1996) described several types of measures typically used in
organizational research and identified the type(s) of measurement error affecting
each of them in various situations For each measure below indicate the types of
error and sources of error that are most likely to affect it Then indicate what

C11 Suppose you had conducted research on the relationship between organizational
commitment and rigidity of organizational structure in 200 firms Your measure
of rigidity was based on number of organizational authority levels and the degree
to which written organizational rules existed and defined role behaviors for
employees Thus an organization with a large number of organizational levels
and specific written policies defining appropriate role behaviors for employees
would score high on rigidity of organizational structure After analyzing your
data you find that there is a statistically significant negative correlation between
commitment and rigidity which is consistent with your hypothesis However the
reliabilities for your two measures are
(1) commitment = 23 (2) rigidity = 83
How should you interpret your results What could you do to fix this situation

and supports continuous learning Describe how you would measure organizational
climate in this case Specify (a) the level (ie individual group organization) at
which the construct exists (b) the level at which you would measure the construct
and (c) the procedures that you would use to establish that measurement is aligned
with theory (ie the construct validity of the measure)
E) General (Measurement)
E1 Studies in organizational behavior research often rely on single-item measures of
key constructs The use of single-item measures has long been criticized based
on the premise that single-item measures are unreliable However Wanous
(Wanous amp Hudy 2001 Wanous amp Reichers 1996 Wanous Reichers amp Hudy
1997) has recently argued that single-item measures can exhibit adequate
reliability Wanous based this conclusion on a procedure for estimating the
reliability of single-item measures using the classic formula for correction for
attenuation Subsequent studies have yielded mixed results regarding the
conclusions of Wanous (eg Loo amp Kells 1998 Nagy 2002) and the veracity
of the perspective advocated by Wanous remains in question Summarize and
assess the arguments for and against the use of single-item measures and
evaluate the procedure and evidence offered by Wanous regarding the reliability
of single-item measures Based on your assessment and evaluation develop
recommendations regarding the use of single-item measures in organizational
behavior research

E2 Ipsative measures have become prevalent in organizational behavior research
Ipsative measures ask respondents to answer questions relative to one another
such that the scores for all questions sum to the same constant for all respondents
Examples of ipsative measures include rankings Q-sorts and the allocation of a
fixed number of points (eg 100) across a set of response options Ipsative
measures may be contrasted with absolute measures which ask respondents to
answer questions independently from one another Absolute measures are
exemplified by rating scales using an interval or ratio numeric response format
The relative merits of ipsative and absolute measures have been debated for
decades (eg Cornwell amp Dunlap 1994 Hicks 1970 Johnson Wood amp
Blinkhorn 1988 Saville amp Wilson 1991 1992) yet the fundamental issues
underlying this debate have not been adequately addressed in organizational
behavior research For example measures of organizational culture and values
are often ipsative and some researchers advocate these measures over absolute
measures (eg Meglino amp Ravlin 1987 OReilly Chatman amp Caldwell 1991
Ravlin amp Meglino 1987 see also Rokeach amp Ball-Rokeach 1989) Review the
relative merits of absolute and ipsative measures Based on your review which
form of measurement is most appropriate and why Do your conclusions depend
on the construct being measured If so what types of constructs are best suited to
ipsative measures and what types are best suited to absolute measures Next
apply your conclusions to the measurement of culture and values in
organizations What specific arguments have been advanced in favor of ipsative
measures of culture and values How sound are these arguments Should ipsative
measures be used in the study of organizational culture and values If not how
can absolute measures of culture and values be developed that address the
concerns voiced by advocates of ipsative measures Provide a specific example

E5 Suppose Roberta Von Eisenbrick is a researcher interested in the consequences of
AFFECTIVE CONFLICT (AC) in decision-making teams She gets access to a
variety of outcomes assessment committees at each of 87 different schools in
the Dallas Independent School District and gains permission to tape-record two
of their meetings (one in February and one in March) Such committees have
been formed to develop quantitative ways to track pursuit of school goals and
provide accountability to local and state governments These are often divisive
teams with heated meetings because what gets assessed is what usually gets
rewarded After both of these meetings the committee members each
fill out a short questionnaire that contains 20 Likert-type items measuring how
much AC occurred (eg People in our group often get angry with each other)
The individual scores are summed across items then averaged across team
members to come up with a group-level AC score for each of the 87 2
meetings The same procedures are followed for a 5-item measure of Group
Cohesiveness (GC) which is predicted to be reduced by higher levels of AC
Roberta also listens to every tape and from her expert judgment she rates each
groups meetings on the same 20 items Those 20 ratings are summed for each of
the 87 2 meetings Now Roberta is interested in evaluating her measure She
wants it to have excellent psychometric properties including reliability and
construct validity

(a) Please define both of these terms (b) Sketch a conceptual model to show how
each relates to main effects (c) Using variables of your choice please write
hypotheses to reflect both (d) Explain how each is tested analytically
D2 Discuss moderators and mediators Provide an example of how (1) a moderating
variable influences the relationship between the independent and dependent
variable and how (2) a mediating variable influences the relationship between
the independent and dependent variable Describe how you would test for both
moderation and mediation using regression
D3 Many theories in organizational research predict that the effects of one variable
on another are moderated by a third variable Such moderator effects are
typically tested by entering the product of two variables as a predictor after
controlling for the two variables that constitute the product Several researchers
have pointed out that this product is often highly correlated with the squares of
the two constituent variables and have suggested that moderating effects may be
tested after controlling not only for the two constituent variables but also their
squares (eg Cortina 1993 Ganzach 1998 Lubinski amp Humphreys 1990
MacCallum amp Mar 1995) Discuss the strengths and weaknesses of this
approach as compared to methods that use only the product term and its
constituent variables Conclude with recommendations as to when and under
what conditions organizational researchers should test moderator effects with the
squares of the constituent variables in the equation

D4 Assume you are interested in studying relationships amongst three variables X
Y and Z Your first hypothesis posits Z as a mediator of the relationship between
X and Y Your second hypothesis posits Z as a moderator of the relationship
between X and Y Draw the figures depicting each of these hypothesized
relationships and describe (make sure to write regression equations) how you
would test each of these hypotheses
D5 The amount of time and effort that the average person pours into his or her job
has risen steadily over the last two decades such that the average person now is
working one more week per year than the average person in the mid 1970s This
steady increase has fueled research interest in the construct of Job Burnout (JB)
which is an emotional and physical exhaustion associated with ones work
Organizational Stress (OS) the perception of greater demands than available
resources in ones work environment is thought to be one of the chief
antecedents of JB However time spent under OS is thought to make its affects
on JB accumulate or worsen Work Role Withdrawal (WRW) the avoidance of
responsibilities or the deliberate reduction of inputs to ones job is believed to be
the chief consequence of JB
a Formally state these ideas as verbal hypotheses as equations and as a complex
directed graph (circle amp arrow diagram)
b Conceptually what is a mediator Define the term and identify the mediator in
your hypotheses in (a) What elements or steps in a study design (not statistics)
that would be helpful for detecting the mediating relationship that was proposed

subdomains of management Further demonstrate your understanding of
moderator variables by picking which variable in (a) is the moderator Show the
moderating relationship in an X-Y (or multi-layered) chart Again what elements
or steps in a study design (not statistics) would be helpful for detecting the
moderating effect implied above

scores on 25 predictor variables (eg measures of education job experience job
tenure job aptitude personality) that were measured when the individuals were hired
(between April 1987 and May 1988) She had data from only the 110 subjects (60
males and 50 females) who were hired during the period and were still employed by
the firm One objective of your analysis (analyses) is to determine how well the

behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows
Anomie Index -standardized interval level measure tapping multiple dimensions
The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)
F5 Researchers collected data from a sample of 350 companies on the following
variables
size (measured as number of employees)
Business Strategy (a nominal variable with 2 response options low-cost provider or
differentiator)
HR Strategy (a nominal variable with 2 response categories High commitment or
low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

I2 A study examined the effects of gender and pre-training motivation on the transfer of
training in terms of improved performance for 123 new industrial managers The
training was on supervisory skills and the dependent variable was based on the
appraisal of the supervisors performance before the training and three months after
the training The performance appraisal data were collected for research purposes
only and resulted in a total transfer score from 1 to 25 with 1 being low Pre-training
motivation was based on a 12 item Likert scale with an alpha of 86 Two groups
were identified for the pre-training motivation variable - the bottom 13 (low) and the
top 13 (high) Table 1 contains the ANOVA results and Table 2 contains the cell

mirrors Explain both sides of the debate and then lay out the role of meta-analysis
as you see it within the time span of your career as an academic To do this use
examples of already written (or yet to be written) articles as models
J5 A frequent criticism of non-quantitative research summaries (literature reviews) is
that researchers do not carefully examine how particular research designs might have
affected the statistical outcomes of the studies included in the literature review Meta-
analysis however allows one to statistically examine such effects Assume you are
conducting a meta-analysis of the relationship between leader behaviors and group
productivity Briefly describe the steps you would take in conducting a meta-
analysis What aspects of the original research designs would you examine in your
meta-analysis What steps would you take in gathering and coding data to enhance
the credibility of your analysis

and discuss the assumptions of the general linear model Multiple regression
ANOVA and principle components (factor) analysis are based on the general linear
model For each of those three statistical procedures describe and discuss the
following
a The type of data necessary for using the technique appropriately

assumptions usage and limitations
O3 How do exploratory and confirmatory factor analysis differ What are the
advantages and disadvantages of each
O4 Describe the differences between exploratory factor analysis (EFA) and
confirmatory factor analysis (CFA) When would you use one verses another
Are there ways to use EFA in a confirmatory way Can you use CFA in an
exploratory way Also describe the difference in principal components analysis
(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression

information in each matrix and its purpose
(2) For what purpose do researchers use factor analysis Explain In the process
provide a very brief description of a study for which factor analysis would be a
useful data analytic technique
O7 Factor analysis is an important statistical technique in organizational research

c the type of quantitative output that results from applying the technique
d how a researcher would use the output in his or her research

f the important issues and problems in using the technique
P) Structural Equation Models
P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)
Please comment on these restrictions versus access argument Which side do you
take
What are the strengths of SEM Give some examples
What are the weaknesses of SEM Give some examples

B14 In describing their notion of the collective mind Karl E Weick and Karlene H
Roberts note Our focus is at once on individuals and the collective since only
individuals can contribute to a collective mind but a collective mind is distinct
from an individual because it inheres in the pattern of interrelated activities
among many people (p 360) Collective mind is not indexed by within-group
similarity of attitudes ideas or activities A collective mind is one in which
many people or many groups integrate their different attitudes ideas and
activities heedfully As Weick and Roberts note People act heedfully when
they act more or less carefully critically consistently purposefully attentively
studiously vigilantly conscientiously pertinaciously (p 361)
The idea of the collective mind as heedful interrelating is developed in the
following excerpt When people make efforts to interrelate these efforts can
range from heedful to heedless The more heed reflected in a pattern of
interrelations the more developed the collective mind and the greater the
capability to comprehend unexpected events that evolve rapidly in unexpected
ways When we say that a collective mind comprehends unexpected events we
mean that heedful interrelating connects sufficient know-how to meet situational
demands For organizations concerned with reliability those developments
often consist of unexpected non-sequential interaction (p366)
An example of heedful interrelating occurs as a pilot lands herhis aircraft on the
deck of an aircraft carrier The pilot does not actually land She is recovered
A recovery is an interrelated set of activities among air traffic controllers
landing signal officers the control tower navigators deck hands the helmsman
driving the ship etc These activities can be interrelated more or less heedfully
depending on the care with which the different units contribute represent the
situation and subordinate their activities to the single purpose of successful
recovery (p 363)
You are to design a two-part study
Part I You are to design a measurement study which assesses heedful
interrelating (ie collective mind) with a quantitative measure in a replication
of an aircraft carrier flight deck or other situation of your choosing Describe
your research strategies including operationalization of the variable selection of
the sample subjects data collection data analysis and so on for the purpose of
developing a measure of heedful interrelating
Part II Using the measurement tool developed in Part I and any other tools as
needed describe how you would design a study which would compare heedful
interrelating across organizations Choose at least one macro-organizational
variable (eg technology environment) as your basis of comparison Here you
must describe how you would make your selection of organizations to be
compared your data collection procedure data analysis and so on
B15 Many organizations in the United States have installed cross-functional teams to
counteract the silo mentality of traditional bureaucratic structure Preliminary
evidence of the effectiveness of cross-functional teams however is mixed --
some organizations have claimed success and others have reported failures The
evidence moreover is predominantly anecdotal--written for trade magazines by
the organizations themselves Since there have been few rigorous empirical
field studies assessing the effectiveness of cross functional teams the National
Science Foundation has decided to fund research on the topic
Assume that you are submitting a research proposal to NSF for a grant to
research the effectiveness of cross-functional teams Describe in detail and
thoroughly explain the research design sampling plan data collection
procedures ethical issues and proposed data analysis for your research design
Be sure to discuss the internal and external validity of your research Which
validity threats are ruled out and which remain NSF also requires that you
provide a statement and defense of the explicit philosophy of science underlying
your research Describe your philosophy of science and discuss how your
research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but
you must also demonstrate to NSF that you are a competent researcher It is
absolutely vital to NSF that the principal researcher (you) is knowledgeable
about the proposed research methodologies Therefore be sure that you always
carefully describe and give technical explanations for each component of your
research design and explain all technical terms (eg Cronbach alpha KR-20
Likert scale)
B16 Assume that you are submitting a research proposal to the Department of
Commerce (DoC) for a grant to research the effectiveness of virtual work teams
A virtual work team is a leaderless collection of individuals who are
geographically separate from one another and share their expertise using
internet media such as a listserver or Lotus notes The DoC requires that the
researcher use both qualitative and quantitative methods to gather data Describe
in detail and thoroughly explain the research design sampling plan data
collection procedures ethical issues and proposed data analysis for your
research design Be sure to discuss the internal and external validity of your
research Which validity threats are ruled out and which remain The DoC also
requires that you provide a statement and defense of the explicit philosophy of
science underlying your research Describe your philosophy of science and
discuss how your research design is consistent with your philosophy
REMEMBER Be thorough You not only must design effective research but
you must also demonstrate to DoC that you are a competent researcher It is

5 MEASUREMENT
A) Measurement Terms
A1 There are four levels of measurement rigor in management research Discuss each
one What properties do measurements at each level have (ie how much
information do the numbers from each level of measurement convey) How can the
numbers be changed (transformed) and still retain the properties of their
measurement level Pick one construct from a favorite research domain and give an
example of an operationalization of that construct at each of the four levels of
measurement rigor (provide arguments about why you think those examples reflect
each level) Lastly treat each examplelevel as a dependent variable in some
statistical analysis Given an example of a statistical technique appropriate for
analyzing data at that level of measurement rigor
A2 Define (and discuss important features or issues concerning) the following
constructs measurement (Define any six terms)
1 Construct validity 6 Item analysis
2 Likert scaling 7 Semantic differential
3 Cronbachs alpha 8 True score
4 Unobtrusive (trace) measurement 9 Generalizability theory
5 Interval scale 10 Criterion-related validity
11 Sociometric choice measures
B) Operationalization
B1 a) You are conducting a study which requires you to measure Hong Kong real
estate agents self-assessment of performance Since there is no existing
measurement available you have to develop the instrument by yourself
Describe how you would develop the measurement assuming that you have no
idea of how many dimension the construct has
b) Suppose you have developed an instrument consists of 20 questions
measuring 4 dimensions (5 items per dimension) from (a) You collected data
from another 300 real estate agents to validate your instrument Explain how
TH
you would use structural equations model (SEM) to examine the reliability and
validity of the instrument What are other concerns about reliability and validity
that are not addressed by this approach
B2 The research and business world have been fascinated with the concept of
organizational culture However operationalizing this construct has been a
difficult task Discuss the ways in which the construct has been operationalized
(eg technique static v dynamic sample selection generalizability) Critically
analyze each of these methodologies Then choose a methodology you would
use to examine organizational culture and defend your choice Describe how
you would study culture and what more would be known about culture as a
result of your study
B3 Suppose you are setting out to develop a new measure of a construct You want
this measure to be used in survey research and you want to establish its validity
and reliability Your goal is to have at the end of the process a measure that is
defensible and likely to be widely accepted by other researchers studying that
construct What steps would you take to conduct such a program of research
For each step explain the purpose of that step explain why that step is
important explain what methods and statistical procedures you would employ at
each step and explain what evidence you would hope to gather at each step
B4 Assume you are interested in constructing a new measure of (fill in with a
relevant variable from your field) Detail the major concerns that need to be
addressed and the steps that need to be taken in working toward validating this
new measure
B5 Assume that you recently read an article on workplace violence which you
found very interesting The authors argued that one of the predictors of
workplace violence was a construct called propensity to be violent and used a
one-item measure as follows How likely are you to become violent when
provoked You had serious doubts about the authors measure and decided to
develop your own
(a) How would you go about developing items to measure propensity to be
violent
(b) How would you determine whether the instrument was reliable
How would you determine whether the instrument was valid
B6 A concern in organizations is retirement of baby boomers within the next 5 -
10 years This concern is focused on the loss of older employees with skills
critical to the core business functions of organizations In order to continue to
have employees with those critical skills it seems necessary to retrain some
older workers However past practice in most organizations has been not to
retrain older workers for a variety of reasons mostly financial A researcher
working for the Human Resources Department of a large corporation - 13500
employees in 12 different plant locations - hypothesizes that the major reason
for not retraining older workers is ingrained in the culture of the corporation
IC
The researcher feels that older workers are not as highly valued as younger
workers in terms of their potential usefulness after retraining The researcher
searched the literature but found nothing in the existing literature to measure
the cultural value construct What should the researcher do to establish a reliable

C10 Schmidt and Hunter (1996) described several types of measures typically used in
organizational research and identified the type(s) of measurement error affecting
each of them in various situations For each measure below indicate the types of
error and sources of error that are most likely to affect it Then indicate what
could be done to reduce errors of measurement andor what can be done to
control for errors statistically

C11 Suppose you had conducted research on the relationship between organizational
commitment and rigidity of organizational structure in 200 firms Your measure
of rigidity was based on number of organizational authority levels and the degree
to which written organizational rules existed and defined role behaviors for
employees Thus an organization with a large number of organizational levels
and specific written policies defining appropriate role behaviors for employees
would score high on rigidity of organizational structure After analyzing your
data you find that there is a statistically significant negative correlation between
commitment and rigidity which is consistent with your hypothesis However the
reliabilities for your two measures are
(1) commitment = 23 (2) rigidity = 83
How should you interpret your results What could you do to fix this situation
Describe the specific steps (in order) you would follow to develop a more
reliable measure of commitment

challenges in terms of designing the research measuring variables and collecting
and analyzing the data Assume that you are interested in aggregating data (eg

Organizational climate is operationalized as a shared consensual aspect of the
organization -- the shared perception among employees that the organization values
and supports continuous learning Describe how you would measure organizational
climate in this case Specify (a) the level (ie individual group organization) at
which the construct exists (b) the level at which you would measure the construct
and (c) the procedures that you would use to establish that measurement is aligned
with theory (ie the construct validity of the measure)
E) General (Measurement)
E1 Studies in organizational behavior research often rely on single-item measures of
key constructs The use of single-item measures has long been criticized based
on the premise that single-item measures are unreliable However Wanous
(Wanous amp Hudy 2001 Wanous amp Reichers 1996 Wanous Reichers amp Hudy
1997) has recently argued that single-item measures can exhibit adequate
reliability Wanous based this conclusion on a procedure for estimating the
reliability of single-item measures using the classic formula for correction for
attenuation Subsequent studies have yielded mixed results regarding the
conclusions of Wanous (eg Loo amp Kells 1998 Nagy 2002) and the veracity
of the perspective advocated by Wanous remains in question Summarize and
assess the arguments for and against the use of single-item measures and
evaluate the procedure and evidence offered by Wanous regarding the reliability
of single-item measures Based on your assessment and evaluation develop
recommendations regarding the use of single-item measures in organizational
behavior research

E2 Ipsative measures have become prevalent in organizational behavior research
Ipsative measures ask respondents to answer questions relative to one another
such that the scores for all questions sum to the same constant for all respondents
Examples of ipsative measures include rankings Q-sorts and the allocation of a
fixed number of points (eg 100) across a set of response options Ipsative
measures may be contrasted with absolute measures which ask respondents to
answer questions independently from one another Absolute measures are
exemplified by rating scales using an interval or ratio numeric response format
The relative merits of ipsative and absolute measures have been debated for
decades (eg Cornwell amp Dunlap 1994 Hicks 1970 Johnson Wood amp
Blinkhorn 1988 Saville amp Wilson 1991 1992) yet the fundamental issues
underlying this debate have not been adequately addressed in organizational
behavior research For example measures of organizational culture and values
are often ipsative and some researchers advocate these measures over absolute
measures (eg Meglino amp Ravlin 1987 OReilly Chatman amp Caldwell 1991
Ravlin amp Meglino 1987 see also Rokeach amp Ball-Rokeach 1989) Review the
relative merits of absolute and ipsative measures Based on your review which
form of measurement is most appropriate and why Do your conclusions depend
on the construct being measured If so what types of constructs are best suited to
ipsative measures and what types are best suited to absolute measures Next
apply your conclusions to the measurement of culture and values in
organizations What specific arguments have been advanced in favor of ipsative
measures of culture and values How sound are these arguments Should ipsative
measures be used in the study of organizational culture and values If not how
can absolute measures of culture and values be developed that address the
concerns voiced by advocates of ipsative measures Provide a specific example
of the type of measure you would propose

facets of a concept Although such measures are prevalent and in some cases are

and methodological problems Describe the specific problems associated with
measures that use items representing different facets of a concept Compare these

E5 Suppose Roberta Von Eisenbrick is a researcher interested in the consequences of
AFFECTIVE CONFLICT (AC) in decision-making teams She gets access to a
variety of outcomes assessment committees at each of 87 different schools in
the Dallas Independent School District and gains permission to tape-record two
of their meetings (one in February and one in March) Such committees have
been formed to develop quantitative ways to track pursuit of school goals and
provide accountability to local and state governments These are often divisive
teams with heated meetings because what gets assessed is what usually gets
rewarded After both of these meetings the committee members each
fill out a short questionnaire that contains 20 Likert-type items measuring how
much AC occurred (eg People in our group often get angry with each other)
The individual scores are summed across items then averaged across team
members to come up with a group-level AC score for each of the 87 2
meetings The same procedures are followed for a 5-item measure of Group
Cohesiveness (GC) which is predicted to be reduced by higher levels of AC
Roberta also listens to every tape and from her expert judgment she rates each
groups meetings on the same 20 items Those 20 ratings are summed for each of
the 87 2 meetings Now Roberta is interested in evaluating her measure She
wants it to have excellent psychometric properties including reliability and
construct validity

D) ModeratorsMediators
D1 Moderation and mediation provide different ways to model third variable effects
(a) Please define both of these terms (b) Sketch a conceptual model to show how
each relates to main effects (c) Using variables of your choice please write
hypotheses to reflect both (d) Explain how each is tested analytically
D2 Discuss moderators and mediators Provide an example of how (1) a moderating
variable influences the relationship between the independent and dependent
variable and how (2) a mediating variable influences the relationship between
the independent and dependent variable Describe how you would test for both
moderation and mediation using regression
D3 Many theories in organizational research predict that the effects of one variable
on another are moderated by a third variable Such moderator effects are
typically tested by entering the product of two variables as a predictor after
controlling for the two variables that constitute the product Several researchers
have pointed out that this product is often highly correlated with the squares of
the two constituent variables and have suggested that moderating effects may be
tested after controlling not only for the two constituent variables but also their
squares (eg Cortina 1993 Ganzach 1998 Lubinski amp Humphreys 1990
MacCallum amp Mar 1995) Discuss the strengths and weaknesses of this
approach as compared to methods that use only the product term and its
constituent variables Conclude with recommendations as to when and under
what conditions organizational researchers should test moderator effects with the
squares of the constituent variables in the equation

D4 Assume you are interested in studying relationships amongst three variables X
Y and Z Your first hypothesis posits Z as a mediator of the relationship between
X and Y Your second hypothesis posits Z as a moderator of the relationship
between X and Y Draw the figures depicting each of these hypothesized
relationships and describe (make sure to write regression equations) how you
would test each of these hypotheses
D5 The amount of time and effort that the average person pours into his or her job
has risen steadily over the last two decades such that the average person now is
working one more week per year than the average person in the mid 1970s This
steady increase has fueled research interest in the construct of Job Burnout (JB)
which is an emotional and physical exhaustion associated with ones work
Organizational Stress (OS) the perception of greater demands than available
resources in ones work environment is thought to be one of the chief
antecedents of JB However time spent under OS is thought to make its affects
on JB accumulate or worsen Work Role Withdrawal (WRW) the avoidance of
responsibilities or the deliberate reduction of inputs to ones job is believed to be
the chief consequence of JB
a Formally state these ideas as verbal hypotheses as equations and as a complex
directed graph (circle amp arrow diagram)
b Conceptually what is a mediator Define the term and identify the mediator in
your hypotheses in (a) What elements or steps in a study design (not statistics)
that would be helpful for detecting the mediating relationship that was proposed

subdomains of management Further demonstrate your understanding of
moderator variables by picking which variable in (a) is the moderator Show the
moderating relationship in an X-Y (or multi-layered) chart Again what elements
or steps in a study design (not statistics) would be helpful for detecting the
moderating effect implied above

for differences among the different levels or cells of a categorical variable In your
description you should discuss among other things

recommendations You conduct a well-designed controlled study (details are unimportant) and discover students who use the new book perform 10 better on a standardized subject
matter exam than those using the old book (p = 027) Both books are readily availabe their prices are almost identical and both are equally acceptable to the instructors What is your recommendation to the chair
F1 Attached is the beginning of an article Your task is to write the results section by
1 making up and reporting plausible descriptive statistics that will help the
reader understand the results of the statistical tests you report and the nature of your
sample (Hint this can be presented in the form of a table)
2 describing and defending your choice of appropriate statistical tests of the
hypotheses and the steps that you would go through in carrying out these tests
3 making up and reporting results of these tests that are consistent with your
descriptive statistics and with any information in the rest of the article about the
results found (Hint this can be presented in the form of a table)
4 describing how well these results provide support for the hypotheses You
may want to note any relevant threats to validity here
Be sure to state any assumptions you make
F2 Assume that the Personnel Manager of a local firm Ms B dFlandres hired you to
analyze some data that her assistants had collected over the past several years The
data consist of (a) job performance ratings that were made in June of 1990 and (b)
scores on 25 predictor variables (eg measures of education job experience job
tenure job aptitude personality) that were measured when the individuals were hired
(between April 1987 and May 1988) She had data from only the 110 subjects (60
males and 50 females) who were hired during the period and were still employed by
the firm One objective of your analysis (analyses) is to determine how well the
performance criterion can be predicted by the predictors What strategy would you
use in analyzing the data Describeexplain (b) Is sample size an issue for your
analyses Explain If it is what will you do to deal with problems stemming from
sample size Assume that no additional data can be collected at this time (c) Some
preliminary analyses that you do reveal that five of the predictor variables correlate
(zero-order basis) about 75 with one another Will this influence the analyses that
you use Will it influence the validity of conclusions derived from your proposed
analyses (d) Ms dFlandres is interested in knowing if the predictor variables are
equally effective in predicting the job success of males and females What analysis
or analyses would you do to deal with this issue
F3 Assume that you have been provided with data on 12 conceptually distinct variables
that are moderately correlated with one another at the empirical level The data are
from students in four different college majors ie astronomy (A) biology (B)
criminology (C) and demography (D) The 12 measured variables fall into the
general categories of mental health (tension emotional withdrawal hallucinations
guilt feelings blunted affect and suspiciousness) and job satisfaction (work itself
supervision co-workers pay promotion prospects and working conditions) Your
task is to determine if the individuals in the four college majors differ from one
another on the 12 measured variables
(a) What statistical technique(s) would you use to test for group differences
Explain Be specific about the procedures(s) that you would use
(b) What statistical estimate would you use to estimate the extent to which the
groups differ from one another Be specific
F4 The following statistical table published in a recent issue of Work amp Occupations
was taken from an article discussing variables influencing resistance and citizenship
behaviors in the workplace Resistance behaviors include playing dumb withholding
effort work avoidance subverting particular managers and sabotage Citizenship
behaviors include cooperation engaging in peer training use of insider knowledge to
facilitate production commitment to organizational goals giving extra effort freely
Both measures are global constructs aggregated to the interval level and
standardized
The table reports the results of a series of ordinary least squares regression equations
with standardized coefficients Explain the meaning of the statistics presented What
do these statistics tell us generally about the relationship between resistance
behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows
Anomie Index -standardized interval level measure tapping multiple dimensions
The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)
F5 Researchers collected data from a sample of 350 companies on the following
variables
size (measured as number of employees)
Business Strategy (a nominal variable with 2 response options low-cost provider or
differentiator)
HR Strategy (a nominal variable with 2 response categories High commitment or
low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

analysis techniques Multiple regression factor analysis discriminant analysis
canonical analysis cluster analysis or MANOVA (Your tutorial can be conceptual
it need not present any mathematical formulas unless you wish to) In your tutorial
be sure to discuss (among other issues)
1 The type of output that results from applying the technique How to interpret
results from the technique
2 The assumptions underlying the technique and the consequences of failures in the
assumptions
(Note Your tutorial will be evaluated on your demonstrated competence with the
statistical method not on the pedagogy of the tutorial)
I) ANOVA
I1 ANOVA Assume that you have conducted a laboratory experiment in which there
were 3 levels of Factor A (a1 a2 a3) and two levels of Factor B (b1 b2) Assume also
that there were 20 subjects in each cell
(a) Prepare a standard analysis of variance (ANOVA) table that is appropriate for this
design Make certain that you specify all effects and the appropriate degrees of
freedom for each effect If you use any abbreviations in your table make certain that
you specify their meaning
(b) Assume that an initial ANOVA analysis found no evidence of an A X B
interaction What if anything would you do with the sum of squares for the
interaction effect
I2 A study examined the effects of gender and pre-training motivation on the transfer of
training in terms of improved performance for 123 new industrial managers The
training was on supervisory skills and the dependent variable was based on the
appraisal of the supervisors performance before the training and three months after
the training The performance appraisal data were collected for research purposes
only and resulted in a total transfer score from 1 to 25 with 1 being low Pre-training
motivation was based on a 12 item Likert scale with an alpha of 86 Two groups
were identified for the pre-training motivation variable - the bottom 13 (low) and the
top 13 (high) Table 1 contains the ANOVA results and Table 2 contains the cell
means
a What experimental design was used in this study
b What assumptions are made in the ANOVA model
c How would you interpret the results in Tables 1 and 2
d What additional computation can be done to evaluate the importance of the
different effects in Table 1
e Using the results in Table 2 show the G x M effect in a graph (It is OK to draw
this graph on a separate sheet and turn it in with your exam)
f Explain what type I and type II error mean in the context of this study

J) Meta-analysis
J1 There exist two categories of literature review narrative and quantitative Each
category as typically implemented has certain advantages and disadvantages
Describe the advantages and disadvantages associated with each approach taking
particular care to enumerate the disadvantages associated with quantitative review
Then offer two ways that meta-analysis might be combined with other analytical
techniques to move beyond the focus of bivariate relationships that is typical of meta-
analysis
J2 Schmidt has argued that primary research does not allow one to discover general
scientific laws but that meta-analytic research does What are the arguments in favor
of or against this position In what areas of research (if any) has Schmidts
prediction come closest to coming true
J3 The so-called (by Hunter Schmidt and Jackson 1983) state of the art meta-
analysis method attempts to account for various sources of error that might produce
apparent variation in effect sizes across studies (a) Discuss the three most important
sources of error that meta-analysis addresses (b) Discuss the potential contribution
that a meta-analysis can make to theory building in the organizational sciences (c)
Describe the circumstances that you would consider when deciding whether to
perform a meta-analysis
J4 Meta-analysis has been hailed as a miracle cure and criticized as smoke and
mirrors Explain both sides of the debate and then lay out the role of meta-analysis
as you see it within the time span of your career as an academic To do this use
examples of already written (or yet to be written) articles as models
J5 A frequent criticism of non-quantitative research summaries (literature reviews) is
that researchers do not carefully examine how particular research designs might have
affected the statistical outcomes of the studies included in the literature review Meta-
analysis however allows one to statistically examine such effects Assume you are
conducting a meta-analysis of the relationship between leader behaviors and group
productivity Briefly describe the steps you would take in conducting a meta-
analysis What aspects of the original research designs would you examine in your
meta-analysis What steps would you take in gathering and coding data to enhance
the credibility of your analysis
K) MTMM
K1 One method often used by social scientists to demonstrate the construct validity of
measures is the multi-trait multi-method matrix developed by Campbell and
Fiske (1959) Briefly describe how this matrix is obtained or constructed by a
researcher and then describe how each of the elements of the matrix is used to
demonstrate the reliability andor construct validity of the measure(s)
IC
K2 Describe the logic of the multi-trait multi-method (MTMM) analysis in terms of
the criteria for evaluating the validity of a set of measurement procedures
Interpret the following MTMM in terms of what it might infer about the validity
of the different measurement procedures You may impose any assumptions on
the data you prefer For example you might want to discuss the matrix under the
assumption that traits A B amp C are mutually independent Please justify and
make explicit any assumptions you make

O3 How do exploratory and confirmatory factor analysis differ What are the
advantages and disadvantages of each
O4 Describe the differences between exploratory factor analysis (EFA) and
confirmatory factor analysis (CFA) When would you use one verses another
Are there ways to use EFA in a confirmatory way Can you use CFA in an
exploratory way Also describe the difference in principal components analysis
(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression
O6 The basic factor analysis model can be represented by the matrix algebraic
equation A B = C
(1) What do each of these matrices represent Be specific as to the type of
information in each matrix and its purpose
(2) For what purpose do researchers use factor analysis Explain In the process
provide a very brief description of a study for which factor analysis would be a
useful data analytic technique
O7 Factor analysis is an important statistical technique in organizational research
Describe factor analysis as an analytical tool including the following issues
a the reasons for using factor analysis
b the type of data necessary for using the technique appropriately
c the type of quantitative output that results from applying the technique
d how a researcher would use the output in his or her research
e how confirmatory factor analysis is different from exploratory
f the important issues and problems in using the technique
P) Structural Equation Models
P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

parameter estimate bias in structural equation modeling Structural Equation

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)
Please comment on these restrictions versus access argument Which side do you
take
What are the strengths of SEM Give some examples
What are the weaknesses of SEM Give some examples

5 MEASUREMENT
A) Measurement Terms
A1 There are four levels of measurement rigor in management research Discuss each
one What properties do measurements at each level have (ie how much
information do the numbers from each level of measurement convey) How can the
numbers be changed (transformed) and still retain the properties of their
measurement level Pick one construct from a favorite research domain and give an
example of an operationalization of that construct at each of the four levels of
measurement rigor (provide arguments about why you think those examples reflect
each level) Lastly treat each examplelevel as a dependent variable in some
statistical analysis Given an example of a statistical technique appropriate for
analyzing data at that level of measurement rigor

estate agents self-assessment of performance Since there is no existing
measurement available you have to develop the instrument by yourself
Describe how you would develop the measurement assuming that you have no
idea of how many dimension the construct has
b) Suppose you have developed an instrument consists of 20 questions
measuring 4 dimensions (5 items per dimension) from (a) You collected data
from another 300 real estate agents to validate your instrument Explain how
TH
you would use structural equations model (SEM) to examine the reliability and
validity of the instrument What are other concerns about reliability and validity
that are not addressed by this approach
B2 The research and business world have been fascinated with the concept of
organizational culture However operationalizing this construct has been a
difficult task Discuss the ways in which the construct has been operationalized
(eg technique static v dynamic sample selection generalizability) Critically
analyze each of these methodologies Then choose a methodology you would
use to examine organizational culture and defend your choice Describe how
you would study culture and what more would be known about culture as a
result of your study
B3 Suppose you are setting out to develop a new measure of a construct You want
this measure to be used in survey research and you want to establish its validity
and reliability Your goal is to have at the end of the process a measure that is
defensible and likely to be widely accepted by other researchers studying that
construct What steps would you take to conduct such a program of research
For each step explain the purpose of that step explain why that step is
important explain what methods and statistical procedures you would employ at
each step and explain what evidence you would hope to gather at each step

relevant variable from your field) Detail the major concerns that need to be
addressed and the steps that need to be taken in working toward validating this
new measure
B5 Assume that you recently read an article on workplace violence which you
found very interesting The authors argued that one of the predictors of
workplace violence was a construct called propensity to be violent and used a
one-item measure as follows How likely are you to become violent when
provoked You had serious doubts about the authors measure and decided to
develop your own
(a) How would you go about developing items to measure propensity to be
violent
(b) How would you determine whether the instrument was reliable
How would you determine whether the instrument was valid
B6 A concern in organizations is retirement of baby boomers within the next 5 -
10 years This concern is focused on the loss of older employees with skills
critical to the core business functions of organizations In order to continue to
have employees with those critical skills it seems necessary to retrain some
older workers However past practice in most organizations has been not to
retrain older workers for a variety of reasons mostly financial A researcher
working for the Human Resources Department of a large corporation - 13500
employees in 12 different plant locations - hypothesizes that the major reason
for not retraining older workers is ingrained in the culture of the corporation
IC
The researcher feels that older workers are not as highly valued as younger
workers in terms of their potential usefulness after retraining The researcher
searched the literature but found nothing in the existing literature to measure
the cultural value construct What should the researcher do to establish a reliable
and valid self-administered paper and pencil measure of this construct namely
the value of retraining older workers
a Please describe and explain the steps in temporal order that the researcher
must follow to develop a measure

the complexity of an organizations manufacturing technology plays in
determining the level of centrality of decision making in the organization
Describe and justify the steps you might follow to develop an operationalization
of the concept of technological complexity What standards would you use to
determine if your operationalization is valid
B8 Organizational researchers have several strategies available to them for
gathering information (eg self-report measures archival measures direct
observation and trace measures) Assume that you are going to conduct
empirical research to assess the role that the structure of the organization plays
in determining the level of organizational effectiveness Briefly review the
strengths and weaknesses of the basic strategies (that is self-report measures
archival measures direct observation and trace measures) for measuring
organizational effectiveness Next describe and justify the steps you would
take to develop an operationalization of the concept of organizational
effectiveness What standards and procedures would you use to determine if
your operationalization is valid
B9 One of the most important topics of recent research has been stress in the work
place One of the most important problems with understanding this literature is
the varying definitions and measurement of this construct Suppose you had
decided to investigate the relationship between stress at the work place and dual
career family happiness
a Since there are multiple ways to measure stress in the work place describe
two ways to do this Hint - avoid using two self-report measures
b Describe how you would decide on the best single measure In doing so
describe the steps you would take in evaluating your measure Be sure to define
your meaning of validity and reliability It is important that your measure have
all the necessary psychometric characteristics so that other scientist can trust the
results of your research
c Be certain that you answer the question Validity for what
d In order to understand the results of your study you need to compare your
measure of stress at work with other measures of this construct How would you
do that
B10 Assume that you have been hired by a national survey research company
Shash Inc to write items that will be used in a national survey of attitudes
toward capital punishment There are a number of criteria that can be used to
guide your item writing What are they Briefly describe five (5) such criteria

impact of interpersonal trust on organizational decision making Describe and
justify the steps you might follow to develop an operationalization of the
interpersonal trust concept
B12 Assume that you are going to conduct empirical field research to assess the role
that employee empowerment plays in determining the level of organizational
commitment of employees Describe and justifyexplain the steps you would
follow to develop a valid and reliable operationalization of the concept of
employee empowerment
Explain the procedures and standards you would use to determine if your
operationalization is valid and reliable
How would you assess the construct validity of such a measure
Discuss issues concerning the level of observation of your measure and level of
analysis of the data
B13 Assume you are interested in developing a new scale to measure construct X
Further assume that you have used previous literature and your own conceptual
development to delineate 2 dimensions of X specifically XF1 and XF2
Describe the steps you would go through in developing testing and evaluating
this new scale With regard to testing and evaluating be sure to consider the
role of factor analysis (both exploratory and confirmatory) and item analysis
Also you will want to make sure that your new multidimensional scale shows
evidence of validity (several kinds) and reliability so be sure to examine these
issues and explain how specific information gathered from the above testing
contributes to these concerns
C) Reliability
4) What is reliability and why is it so important What are the different ways reliability can be
assessed and when is each appropriate
15) What does coefficient alpha assess What are the ways coefficient alpha can be increased
C1 Describe and discuss the concept of reliability and all of its various forms
including their assessment When is each form appropriate and what information
is provided by each index
C2 In establishing congruence between multiple measurements we often compute
indices of reliability andor indices of agreement These two types of indices
address very different questions Your task is to 1) Define reliability and
agreement 2) Explain when each is useful using examples in which one but not
the other is appropriate and 3) Briefly describe two reliability indices and two
agreement indices
C3 Explain reliability in terms of the classical test theory What are the
consequences of unreliable measures in hypothesis testing What are the factors

reliability andor agreement Define reliability and agreement Explain the
differences in reliability and agreement and describe under what conditions
assessing reliability is more appropriate and under what conditions assessing

which each might be appropriate Use examples throughout
C7 What are the consequences of unreliability in a measure
C8 What are some of the conditions that might keep the internal consistency (eg
alpha) of a given measure low Is a low alpha always a sign of a problematic
measure
C9 Define reliability Name some methods of calculating reliability How well do
these methods map up with the definition of reliability What is the impact of the
number of test items and sample size on Chronbachs alpha and why would this
effect occur or not occur (Note Do NOT discuss inter-rater reliability)
C10 Schmidt and Hunter (1996) described several types of measures typically used in
organizational research and identified the type(s) of measurement error affecting
each of them in various situations For each measure below indicate the types of
error and sources of error that are most likely to affect it Then indicate what
could be done to reduce errors of measurement andor what can be done to
control for errors statistically
a Supervisor ratings of subordinates job performance
b Self-ratings of ones own job performance
c Self-reports of ones own job-related attitudes
d Sales figures for a salesperson (or production quantity for a production
worker)
d Aptitude tests taken as part of the hiring process
C11 Suppose you had conducted research on the relationship between organizational
commitment and rigidity of organizational structure in 200 firms Your measure
of rigidity was based on number of organizational authority levels and the degree
to which written organizational rules existed and defined role behaviors for
employees Thus an organization with a large number of organizational levels
and specific written policies defining appropriate role behaviors for employees
would score high on rigidity of organizational structure After analyzing your
data you find that there is a statistically significant negative correlation between
commitment and rigidity which is consistent with your hypothesis However the
reliabilities for your two measures are
(1) commitment = 23 (2) rigidity = 83
How should you interpret your results What could you do to fix this situation
Describe the specific steps (in order) you would follow to develop a more
reliable measure of commitment
C12 (a) Define the concept of reliability (of measures) in a clear concise and
accurate manner (b) Provide a formula that expresses the reliability of a measure
in terms of two components of variance ie total variance and the error
variance
D) Multi-level Assessment
D1 One of the major challenges for group-level research is the issue of aggregation of
individual data to the group level
(a) Under what conditions (eg types of data number of raters) should the various
interrater agreement and reliability methods be used (Rwg Kappa and Weighted
Kappa percent agreement average pairwise correlation ANOVA methods
(interclass correlation coefficient WABA)) What are the advantages and
disadvantages of each of the methods
(b) Explain the controversy between Frank Schmidt Larry James and others
regarding the differences between interrater agreement and interrater reliability
Who is right Do the differences matter in research practice
Defend your answers
(c) Review two articles from the organizational behavior literature that have had to
deal with aggregation issues Critique the methods the authors used to make
aggregation decisions
(d) Provide some advice to researchers regarding what they should do if interrater
agreement and reliability indices indicate that it is not legitimate to aggregate their
data
(e) Provide some ideas for avoiding the need to aggregate in group-level research
through creative research methods and measurement strategies
D2 Cross-levelmulti-level research is becoming more evident in the organizational
research literature This type of research raises many issues and presents many
challenges in terms of designing the research measuring variables and collecting
and analyzing the data Assume that you are interested in aggregating data (eg
from the individual to the group or from the firm to the industry) for one or more
variables What are the major issues you will need to deal with
D3 A researcher wants to measure organizational climate for continuous learning
Organizational climate is operationalized as a shared consensual aspect of the
organization -- the shared perception among employees that the organization values
and supports continuous learning Describe how you would measure organizational
climate in this case Specify (a) the level (ie individual group organization) at
which the construct exists (b) the level at which you would measure the construct
and (c) the procedures that you would use to establish that measurement is aligned
with theory (ie the construct validity of the measure)
E) General (Measurement)
E1 Studies in organizational behavior research often rely on single-item measures of
key constructs The use of single-item measures has long been criticized based
on the premise that single-item measures are unreliable However Wanous
(Wanous amp Hudy 2001 Wanous amp Reichers 1996 Wanous Reichers amp Hudy
1997) has recently argued that single-item measures can exhibit adequate
reliability Wanous based this conclusion on a procedure for estimating the
reliability of single-item measures using the classic formula for correction for
attenuation Subsequent studies have yielded mixed results regarding the
conclusions of Wanous (eg Loo amp Kells 1998 Nagy 2002) and the veracity
of the perspective advocated by Wanous remains in question Summarize and
assess the arguments for and against the use of single-item measures and
evaluate the procedure and evidence offered by Wanous regarding the reliability
of single-item measures Based on your assessment and evaluation develop
recommendations regarding the use of single-item measures in organizational
behavior research

E2 Ipsative measures have become prevalent in organizational behavior research
Ipsative measures ask respondents to answer questions relative to one another
such that the scores for all questions sum to the same constant for all respondents
Examples of ipsative measures include rankings Q-sorts and the allocation of a
fixed number of points (eg 100) across a set of response options Ipsative
measures may be contrasted with absolute measures which ask respondents to
answer questions independently from one another Absolute measures are
exemplified by rating scales using an interval or ratio numeric response format
The relative merits of ipsative and absolute measures have been debated for
decades (eg Cornwell amp Dunlap 1994 Hicks 1970 Johnson Wood amp
Blinkhorn 1988 Saville amp Wilson 1991 1992) yet the fundamental issues
underlying this debate have not been adequately addressed in organizational
behavior research For example measures of organizational culture and values
are often ipsative and some researchers advocate these measures over absolute
measures (eg Meglino amp Ravlin 1987 OReilly Chatman amp Caldwell 1991
Ravlin amp Meglino 1987 see also Rokeach amp Ball-Rokeach 1989) Review the
relative merits of absolute and ipsative measures Based on your review which
form of measurement is most appropriate and why Do your conclusions depend
on the construct being measured If so what types of constructs are best suited to
ipsative measures and what types are best suited to absolute measures Next
apply your conclusions to the measurement of culture and values in
organizations What specific arguments have been advanced in favor of ipsative
measures of culture and values How sound are these arguments Should ipsative
measures be used in the study of organizational culture and values If not how
can absolute measures of culture and values be developed that address the
concerns voiced by advocates of ipsative measures Provide a specific example
of the type of measure you would propose

E3 In organizational research measures often consist of items that represent different
facets of a concept Although such measures are prevalent and in some cases are
advocated (eg Law et al 1998 1999) they can present a variety of conceptual
and methodological problems Describe the specific problems associated with
measures that use items representing different facets of a concept Compare these
problems with the purported advantages of such measures Conclude by

b Experimental research
c Qualitative field research
d Quantitative field research
E5 Suppose Roberta Von Eisenbrick is a researcher interested in the consequences of
AFFECTIVE CONFLICT (AC) in decision-making teams She gets access to a
variety of outcomes assessment committees at each of 87 different schools in
the Dallas Independent School District and gains permission to tape-record two
of their meetings (one in February and one in March) Such committees have
been formed to develop quantitative ways to track pursuit of school goals and
provide accountability to local and state governments These are often divisive
teams with heated meetings because what gets assessed is what usually gets
rewarded After both of these meetings the committee members each
fill out a short questionnaire that contains 20 Likert-type items measuring how
much AC occurred (eg People in our group often get angry with each other)
The individual scores are summed across items then averaged across team
members to come up with a group-level AC score for each of the 87 2
meetings The same procedures are followed for a 5-item measure of Group
Cohesiveness (GC) which is predicted to be reduced by higher levels of AC
Roberta also listens to every tape and from her expert judgment she rates each
groups meetings on the same 20 items Those 20 ratings are summed for each of
the 87 2 meetings Now Roberta is interested in evaluating her measure She
wants it to have excellent psychometric properties including reliability and
construct validity

are the essential elements of these critiques What are some remedies to the
problems engendered by significance testing and why have these remedies not
been widely adopted

things that researchers have inappropriately sanctified the p lt 05 level of
significance Describe and critique the arguments for and against the use of
statistical significance testing in empirical research What information other than

D) ModeratorsMediators
D1 Moderation and mediation provide different ways to model third variable effects
(a) Please define both of these terms (b) Sketch a conceptual model to show how
each relates to main effects (c) Using variables of your choice please write
hypotheses to reflect both (d) Explain how each is tested analytically
D2 Discuss moderators and mediators Provide an example of how (1) a moderating
variable influences the relationship between the independent and dependent
variable and how (2) a mediating variable influences the relationship between
the independent and dependent variable Describe how you would test for both
moderation and mediation using regression
D3 Many theories in organizational research predict that the effects of one variable
on another are moderated by a third variable Such moderator effects are
typically tested by entering the product of two variables as a predictor after
controlling for the two variables that constitute the product Several researchers
have pointed out that this product is often highly correlated with the squares of
the two constituent variables and have suggested that moderating effects may be
tested after controlling not only for the two constituent variables but also their
squares (eg Cortina 1993 Ganzach 1998 Lubinski amp Humphreys 1990
MacCallum amp Mar 1995) Discuss the strengths and weaknesses of this
approach as compared to methods that use only the product term and its
constituent variables Conclude with recommendations as to when and under
what conditions organizational researchers should test moderator effects with the
squares of the constituent variables in the equation

D4 Assume you are interested in studying relationships amongst three variables X
Y and Z Your first hypothesis posits Z as a mediator of the relationship between
X and Y Your second hypothesis posits Z as a moderator of the relationship
between X and Y Draw the figures depicting each of these hypothesized
relationships and describe (make sure to write regression equations) how you
would test each of these hypotheses
D5 The amount of time and effort that the average person pours into his or her job
has risen steadily over the last two decades such that the average person now is
working one more week per year than the average person in the mid 1970s This
steady increase has fueled research interest in the construct of Job Burnout (JB)
which is an emotional and physical exhaustion associated with ones work
Organizational Stress (OS) the perception of greater demands than available
resources in ones work environment is thought to be one of the chief
antecedents of JB However time spent under OS is thought to make its affects
on JB accumulate or worsen Work Role Withdrawal (WRW) the avoidance of
responsibilities or the deliberate reduction of inputs to ones job is believed to be
the chief consequence of JB
a Formally state these ideas as verbal hypotheses as equations and as a complex
directed graph (circle amp arrow diagram)
b Conceptually what is a mediator Define the term and identify the mediator in
your hypotheses in (a) What elements or steps in a study design (not statistics)
that would be helpful for detecting the mediating relationship that was proposed
c What is a moderator What are some of the other names for it within various
subdomains of management Further demonstrate your understanding of
moderator variables by picking which variable in (a) is the moderator Show the
moderating relationship in an X-Y (or multi-layered) chart Again what elements
or steps in a study design (not statistics) would be helpful for detecting the
moderating effect implied above
E) Multiple Comparisons
E1 In your role as professional colleague you are called upon to advise another doctoral
student about the appropriate use of multiple comparisons and post hoc tests in
analysis of variance Your student colleague already has been introduced to ANOVA
and multiple regression Specifically you are to write out a description of how to test
for differences among the different levels or cells of a categorical variable In your
description you should discuss among other things
a the statistical and philosophical issues raised by post hoc analysis and data
snooping
b the different multiple comparison methods commonly used by researchers to test
for differences among cell means and
c the advantages and disadvantages of each method
Note Your written description will be evaluated based on your demonstrated
competence with the statistical method not on the pedagogy of your explanation

recommendations You conduct a well-designed controlled study (details are unimportant) and discover students who use the new book perform 10 better on a standardized subject
matter exam than those using the old book (p = 027) Both books are readily availabe their prices are almost identical and both are equally acceptable to the instructors What is your recommendation to the chair
F1 Attached is the beginning of an article Your task is to write the results section by
1 making up and reporting plausible descriptive statistics that will help the
reader understand the results of the statistical tests you report and the nature of your
sample (Hint this can be presented in the form of a table)
2 describing and defending your choice of appropriate statistical tests of the
hypotheses and the steps that you would go through in carrying out these tests
3 making up and reporting results of these tests that are consistent with your
descriptive statistics and with any information in the rest of the article about the
results found (Hint this can be presented in the form of a table)
4 describing how well these results provide support for the hypotheses You
may want to note any relevant threats to validity here
Be sure to state any assumptions you make
F2 Assume that the Personnel Manager of a local firm Ms B dFlandres hired you to
analyze some data that her assistants had collected over the past several years The
data consist of (a) job performance ratings that were made in June of 1990 and (b)
scores on 25 predictor variables (eg measures of education job experience job
tenure job aptitude personality) that were measured when the individuals were hired
(between April 1987 and May 1988) She had data from only the 110 subjects (60
males and 50 females) who were hired during the period and were still employed by
the firm One objective of your analysis (analyses) is to determine how well the
performance criterion can be predicted by the predictors What strategy would you
use in analyzing the data Describeexplain (b) Is sample size an issue for your
analyses Explain If it is what will you do to deal with problems stemming from
sample size Assume that no additional data can be collected at this time (c) Some
preliminary analyses that you do reveal that five of the predictor variables correlate
(zero-order basis) about 75 with one another Will this influence the analyses that
you use Will it influence the validity of conclusions derived from your proposed
analyses (d) Ms dFlandres is interested in knowing if the predictor variables are
equally effective in predicting the job success of males and females What analysis
or analyses would you do to deal with this issue
F3 Assume that you have been provided with data on 12 conceptually distinct variables
that are moderately correlated with one another at the empirical level The data are
from students in four different college majors ie astronomy (A) biology (B)
criminology (C) and demography (D) The 12 measured variables fall into the
general categories of mental health (tension emotional withdrawal hallucinations
guilt feelings blunted affect and suspiciousness) and job satisfaction (work itself
supervision co-workers pay promotion prospects and working conditions) Your
task is to determine if the individuals in the four college majors differ from one
another on the 12 measured variables
(a) What statistical technique(s) would you use to test for group differences
Explain Be specific about the procedures(s) that you would use
(b) What statistical estimate would you use to estimate the extent to which the
groups differ from one another Be specific
F4 The following statistical table published in a recent issue of Work amp Occupations
was taken from an article discussing variables influencing resistance and citizenship
behaviors in the workplace Resistance behaviors include playing dumb withholding
effort work avoidance subverting particular managers and sabotage Citizenship
behaviors include cooperation engaging in peer training use of insider knowledge to
facilitate production commitment to organizational goals giving extra effort freely
Both measures are global constructs aggregated to the interval level and
standardized
The table reports the results of a series of ordinary least squares regression equations
with standardized coefficients Explain the meaning of the statistics presented What
do these statistics tell us generally about the relationship between resistance
behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows
Anomie Index -standardized interval level measure tapping multiple dimensions
The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)
F5 Researchers collected data from a sample of 350 companies on the following
variables
size (measured as number of employees)
Business Strategy (a nominal variable with 2 response options low-cost provider or
differentiator)
HR Strategy (a nominal variable with 2 response categories High commitment or
low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

I2 A study examined the effects of gender and pre-training motivation on the transfer of
training in terms of improved performance for 123 new industrial managers The
training was on supervisory skills and the dependent variable was based on the

J) Meta-analysis
J1 There exist two categories of literature review narrative and quantitative Each
category as typically implemented has certain advantages and disadvantages
Describe the advantages and disadvantages associated with each approach taking
particular care to enumerate the disadvantages associated with quantitative review
Then offer two ways that meta-analysis might be combined with other analytical
techniques to move beyond the focus of bivariate relationships that is typical of meta-
analysis
J2 Schmidt has argued that primary research does not allow one to discover general
scientific laws but that meta-analytic research does What are the arguments in favor
of or against this position In what areas of research (if any) has Schmidts
prediction come closest to coming true
J3 The so-called (by Hunter Schmidt and Jackson 1983) state of the art meta-
analysis method attempts to account for various sources of error that might produce
apparent variation in effect sizes across studies (a) Discuss the three most important
sources of error that meta-analysis addresses (b) Discuss the potential contribution
that a meta-analysis can make to theory building in the organizational sciences (c)
Describe the circumstances that you would consider when deciding whether to
perform a meta-analysis
J4 Meta-analysis has been hailed as a miracle cure and criticized as smoke and
mirrors Explain both sides of the debate and then lay out the role of meta-analysis
as you see it within the time span of your career as an academic To do this use
examples of already written (or yet to be written) articles as models
J5 A frequent criticism of non-quantitative research summaries (literature reviews) is
that researchers do not carefully examine how particular research designs might have
affected the statistical outcomes of the studies included in the literature review Meta-
analysis however allows one to statistically examine such effects Assume you are
conducting a meta-analysis of the relationship between leader behaviors and group
productivity Briefly describe the steps you would take in conducting a meta-
analysis What aspects of the original research designs would you examine in your
meta-analysis What steps would you take in gathering and coding data to enhance
the credibility of your analysis
K) MTMM
K1 One method often used by social scientists to demonstrate the construct validity of
measures is the multi-trait multi-method matrix developed by Campbell and
Fiske (1959) Briefly describe how this matrix is obtained or constructed by a
researcher and then describe how each of the elements of the matrix is used to
demonstrate the reliability andor construct validity of the measure(s)
IC
K2 Describe the logic of the multi-trait multi-method (MTMM) analysis in terms of
the criteria for evaluating the validity of a set of measurement procedures
Interpret the following MTMM in terms of what it might infer about the validity
of the different measurement procedures You may impose any assumptions on
the data you prefer For example you might want to discuss the matrix under the
assumption that traits A B amp C are mutually independent Please justify and

confirmatory factor analysis (CFA) When would you use one verses another
Are there ways to use EFA in a confirmatory way Can you use CFA in an
exploratory way Also describe the difference in principal components analysis
(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression

P) Structural Equation Models
P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

parameter estimate bias in structural equation modeling Structural Equation

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)
Please comment on these restrictions versus access argument Which side do you
take
What are the strengths of SEM Give some examples
What are the weaknesses of SEM Give some examples

5 MEASUREMENT
A) Measurement Terms
A1 There are four levels of measurement rigor in management research Discuss each
one What properties do measurements at each level have (ie how much
information do the numbers from each level of measurement convey) How can the
numbers be changed (transformed) and still retain the properties of their
measurement level Pick one construct from a favorite research domain and give an
example of an operationalization of that construct at each of the four levels of
measurement rigor (provide arguments about why you think those examples reflect
each level) Lastly treat each examplelevel as a dependent variable in some
statistical analysis Given an example of a statistical technique appropriate for
analyzing data at that level of measurement rigor

estate agents self-assessment of performance Since there is no existing
measurement available you have to develop the instrument by yourself
Describe how you would develop the measurement assuming that you have no
idea of how many dimension the construct has
b) Suppose you have developed an instrument consists of 20 questions
measuring 4 dimensions (5 items per dimension) from (a) You collected data
from another 300 real estate agents to validate your instrument Explain how
TH
you would use structural equations model (SEM) to examine the reliability and
validity of the instrument What are other concerns about reliability and validity
that are not addressed by this approach
B2 The research and business world have been fascinated with the concept of
organizational culture However operationalizing this construct has been a
difficult task Discuss the ways in which the construct has been operationalized
(eg technique static v dynamic sample selection generalizability) Critically
analyze each of these methodologies Then choose a methodology you would
use to examine organizational culture and defend your choice Describe how
you would study culture and what more would be known about culture as a
result of your study
B3 Suppose you are setting out to develop a new measure of a construct You want
this measure to be used in survey research and you want to establish its validity
and reliability Your goal is to have at the end of the process a measure that is
defensible and likely to be widely accepted by other researchers studying that
construct What steps would you take to conduct such a program of research
For each step explain the purpose of that step explain why that step is
important explain what methods and statistical procedures you would employ at
each step and explain what evidence you would hope to gather at each step

relevant variable from your field) Detail the major concerns that need to be
addressed and the steps that need to be taken in working toward validating this
new measure
B5 Assume that you recently read an article on workplace violence which you
found very interesting The authors argued that one of the predictors of
workplace violence was a construct called propensity to be violent and used a
one-item measure as follows How likely are you to become violent when
provoked You had serious doubts about the authors measure and decided to
develop your own
(a) How would you go about developing items to measure propensity to be
violent
(b) How would you determine whether the instrument was reliable
How would you determine whether the instrument was valid
B6 A concern in organizations is retirement of baby boomers within the next 5 -
10 years This concern is focused on the loss of older employees with skills
critical to the core business functions of organizations In order to continue to
have employees with those critical skills it seems necessary to retrain some
older workers However past practice in most organizations has been not to
retrain older workers for a variety of reasons mostly financial A researcher
working for the Human Resources Department of a large corporation - 13500
employees in 12 different plant locations - hypothesizes that the major reason
for not retraining older workers is ingrained in the culture of the corporation
IC
The researcher feels that older workers are not as highly valued as younger
workers in terms of their potential usefulness after retraining The researcher
searched the literature but found nothing in the existing literature to measure
the cultural value construct What should the researcher do to establish a reliable
and valid self-administered paper and pencil measure of this construct namely
the value of retraining older workers

gathering information (eg self-report measures archival measures direct
observation and trace measures) Assume that you are going to conduct
empirical research to assess the role that the structure of the organization plays
in determining the level of organizational effectiveness Briefly review the
strengths and weaknesses of the basic strategies (that is self-report measures
archival measures direct observation and trace measures) for measuring
organizational effectiveness Next describe and justify the steps you would
take to develop an operationalization of the concept of organizational
effectiveness What standards and procedures would you use to determine if
your operationalization is valid
B9 One of the most important topics of recent research has been stress in the work
place One of the most important problems with understanding this literature is
the varying definitions and measurement of this construct Suppose you had
decided to investigate the relationship between stress at the work place and dual
career family happiness
a Since there are multiple ways to measure stress in the work place describe
two ways to do this Hint - avoid using two self-report measures
b Describe how you would decide on the best single measure In doing so
describe the steps you would take in evaluating your measure Be sure to define
your meaning of validity and reliability It is important that your measure have
all the necessary psychometric characteristics so that other scientist can trust the
results of your research

commitment of employees Describe and justifyexplain the steps you would
follow to develop a valid and reliable operationalization of the concept of
employee empowerment
Explain the procedures and standards you would use to determine if your
operationalization is valid and reliable
How would you assess the construct validity of such a measure
Discuss issues concerning the level of observation of your measure and level of
analysis of the data
B13 Assume you are interested in developing a new scale to measure construct X
Further assume that you have used previous literature and your own conceptual
development to delineate 2 dimensions of X specifically XF1 and XF2
Describe the steps you would go through in developing testing and evaluating
this new scale With regard to testing and evaluating be sure to consider the
role of factor analysis (both exploratory and confirmatory) and item analysis
Also you will want to make sure that your new multidimensional scale shows
evidence of validity (several kinds) and reliability so be sure to examine these
issues and explain how specific information gathered from the above testing
contributes to these concerns

C1 Describe and discuss the concept of reliability and all of its various forms
including their assessment When is each form appropriate and what information
is provided by each index
C2 In establishing congruence between multiple measurements we often compute
indices of reliability andor indices of agreement These two types of indices
address very different questions Your task is to 1) Define reliability and
agreement 2) Explain when each is useful using examples in which one but not
the other is appropriate and 3) Briefly describe two reliability indices and two
agreement indices
C3 Explain reliability in terms of the classical test theory What are the
consequences of unreliable measures in hypothesis testing What are the factors

which each might be appropriate Use examples throughout
C7 What are the consequences of unreliability in a measure
C8 What are some of the conditions that might keep the internal consistency (eg
alpha) of a given measure low Is a low alpha always a sign of a problematic
measure
C9 Define reliability Name some methods of calculating reliability How well do
these methods map up with the definition of reliability What is the impact of the
number of test items and sample size on Chronbachs alpha and why would this
effect occur or not occur (Note Do NOT discuss inter-rater reliability)
C10 Schmidt and Hunter (1996) described several types of measures typically used in
organizational research and identified the type(s) of measurement error affecting
each of them in various situations For each measure below indicate the types of
error and sources of error that are most likely to affect it Then indicate what
could be done to reduce errors of measurement andor what can be done to
control for errors statistically
a Supervisor ratings of subordinates job performance
b Self-ratings of ones own job performance
c Self-reports of ones own job-related attitudes
d Sales figures for a salesperson (or production quantity for a production
worker)
d Aptitude tests taken as part of the hiring process
C11 Suppose you had conducted research on the relationship between organizational
commitment and rigidity of organizational structure in 200 firms Your measure
of rigidity was based on number of organizational authority levels and the degree
to which written organizational rules existed and defined role behaviors for
employees Thus an organization with a large number of organizational levels
and specific written policies defining appropriate role behaviors for employees
would score high on rigidity of organizational structure After analyzing your
data you find that there is a statistically significant negative correlation between
commitment and rigidity which is consistent with your hypothesis However the
reliabilities for your two measures are
(1) commitment = 23 (2) rigidity = 83
How should you interpret your results What could you do to fix this situation
Describe the specific steps (in order) you would follow to develop a more
reliable measure of commitment

interrater agreement and reliability methods be used (Rwg Kappa and Weighted
Kappa percent agreement average pairwise correlation ANOVA methods
(interclass correlation coefficient WABA)) What are the advantages and
disadvantages of each of the methods

research literature This type of research raises many issues and presents many
challenges in terms of designing the research measuring variables and collecting
and analyzing the data Assume that you are interested in aggregating data (eg
from the individual to the group or from the firm to the industry) for one or more
variables What are the major issues you will need to deal with
D3 A researcher wants to measure organizational climate for continuous learning
Organizational climate is operationalized as a shared consensual aspect of the
organization -- the shared perception among employees that the organization values
and supports continuous learning Describe how you would measure organizational
climate in this case Specify (a) the level (ie individual group organization) at
which the construct exists (b) the level at which you would measure the construct
and (c) the procedures that you would use to establish that measurement is aligned
with theory (ie the construct validity of the measure)
E) General (Measurement)
E1 Studies in organizational behavior research often rely on single-item measures of
key constructs The use of single-item measures has long been criticized based
on the premise that single-item measures are unreliable However Wanous
(Wanous amp Hudy 2001 Wanous amp Reichers 1996 Wanous Reichers amp Hudy
1997) has recently argued that single-item measures can exhibit adequate
reliability Wanous based this conclusion on a procedure for estimating the
reliability of single-item measures using the classic formula for correction for
attenuation Subsequent studies have yielded mixed results regarding the
conclusions of Wanous (eg Loo amp Kells 1998 Nagy 2002) and the veracity
of the perspective advocated by Wanous remains in question Summarize and
assess the arguments for and against the use of single-item measures and
evaluate the procedure and evidence offered by Wanous regarding the reliability
of single-item measures Based on your assessment and evaluation develop
recommendations regarding the use of single-item measures in organizational
behavior research

E2 Ipsative measures have become prevalent in organizational behavior research
Ipsative measures ask respondents to answer questions relative to one another
such that the scores for all questions sum to the same constant for all respondents
Examples of ipsative measures include rankings Q-sorts and the allocation of a
fixed number of points (eg 100) across a set of response options Ipsative
measures may be contrasted with absolute measures which ask respondents to
answer questions independently from one another Absolute measures are
exemplified by rating scales using an interval or ratio numeric response format
The relative merits of ipsative and absolute measures have been debated for
decades (eg Cornwell amp Dunlap 1994 Hicks 1970 Johnson Wood amp
Blinkhorn 1988 Saville amp Wilson 1991 1992) yet the fundamental issues
underlying this debate have not been adequately addressed in organizational
behavior research For example measures of organizational culture and values
are often ipsative and some researchers advocate these measures over absolute
measures (eg Meglino amp Ravlin 1987 OReilly Chatman amp Caldwell 1991
Ravlin amp Meglino 1987 see also Rokeach amp Ball-Rokeach 1989) Review the
relative merits of absolute and ipsative measures Based on your review which
form of measurement is most appropriate and why Do your conclusions depend
on the construct being measured If so what types of constructs are best suited to
ipsative measures and what types are best suited to absolute measures Next
apply your conclusions to the measurement of culture and values in
organizations What specific arguments have been advanced in favor of ipsative
measures of culture and values How sound are these arguments Should ipsative
measures be used in the study of organizational culture and values If not how
can absolute measures of culture and values be developed that address the

E5 Suppose Roberta Von Eisenbrick is a researcher interested in the consequences of
AFFECTIVE CONFLICT (AC) in decision-making teams She gets access to a
variety of outcomes assessment committees at each of 87 different schools in
the Dallas Independent School District and gains permission to tape-record two
of their meetings (one in February and one in March) Such committees have
been formed to develop quantitative ways to track pursuit of school goals and
provide accountability to local and state governments These are often divisive
teams with heated meetings because what gets assessed is what usually gets
rewarded After both of these meetings the committee members each
fill out a short questionnaire that contains 20 Likert-type items measuring how
much AC occurred (eg People in our group often get angry with each other)
The individual scores are summed across items then averaged across team
members to come up with a group-level AC score for each of the 87 2
meetings The same procedures are followed for a 5-item measure of Group
Cohesiveness (GC) which is predicted to be reduced by higher levels of AC
Roberta also listens to every tape and from her expert judgment she rates each
groups meetings on the same 20 items Those 20 ratings are summed for each of
the 87 2 meetings Now Roberta is interested in evaluating her measure She
wants it to have excellent psychometric properties including reliability and
construct validity

estimating Pick one of those kinds of estimates and provide a rationale for using
it
c What is construct validity Discuss how the (un)reliability of the AC measure
could affect the conclusions one would draw from a study involving it and GC In

validity and the connection between reliability and the probability of Type I or
Type II statistical errors

problems engendered by significance testing and why have these remedies not
been widely adopted

D) ModeratorsMediators
D1 Moderation and mediation provide different ways to model third variable effects
(a) Please define both of these terms (b) Sketch a conceptual model to show how
each relates to main effects (c) Using variables of your choice please write
hypotheses to reflect both (d) Explain how each is tested analytically
D2 Discuss moderators and mediators Provide an example of how (1) a moderating
variable influences the relationship between the independent and dependent
variable and how (2) a mediating variable influences the relationship between
the independent and dependent variable Describe how you would test for both
moderation and mediation using regression
D3 Many theories in organizational research predict that the effects of one variable
on another are moderated by a third variable Such moderator effects are
typically tested by entering the product of two variables as a predictor after
controlling for the two variables that constitute the product Several researchers
have pointed out that this product is often highly correlated with the squares of
the two constituent variables and have suggested that moderating effects may be
tested after controlling not only for the two constituent variables but also their
squares (eg Cortina 1993 Ganzach 1998 Lubinski amp Humphreys 1990
MacCallum amp Mar 1995) Discuss the strengths and weaknesses of this
approach as compared to methods that use only the product term and its
constituent variables Conclude with recommendations as to when and under
what conditions organizational researchers should test moderator effects with the
squares of the constituent variables in the equation

D4 Assume you are interested in studying relationships amongst three variables X
Y and Z Your first hypothesis posits Z as a mediator of the relationship between
X and Y Your second hypothesis posits Z as a moderator of the relationship
between X and Y Draw the figures depicting each of these hypothesized
relationships and describe (make sure to write regression equations) how you
would test each of these hypotheses
D5 The amount of time and effort that the average person pours into his or her job
has risen steadily over the last two decades such that the average person now is
working one more week per year than the average person in the mid 1970s This
steady increase has fueled research interest in the construct of Job Burnout (JB)
which is an emotional and physical exhaustion associated with ones work
Organizational Stress (OS) the perception of greater demands than available
resources in ones work environment is thought to be one of the chief
antecedents of JB However time spent under OS is thought to make its affects
on JB accumulate or worsen Work Role Withdrawal (WRW) the avoidance of
responsibilities or the deliberate reduction of inputs to ones job is believed to be
the chief consequence of JB
a Formally state these ideas as verbal hypotheses as equations and as a complex
directed graph (circle amp arrow diagram)
b Conceptually what is a mediator Define the term and identify the mediator in
your hypotheses in (a) What elements or steps in a study design (not statistics)
that would be helpful for detecting the mediating relationship that was proposed

subdomains of management Further demonstrate your understanding of
moderator variables by picking which variable in (a) is the moderator Show the
moderating relationship in an X-Y (or multi-layered) chart Again what elements
or steps in a study design (not statistics) would be helpful for detecting the
moderating effect implied above

recommendations You conduct a well-designed controlled study (details are unimportant) and discover students who use the new book perform 10 better on a standardized subject
matter exam than those using the old book (p = 027) Both books are readily availabe their prices are almost identical and both are equally acceptable to the instructors What is your recommendation to the chair
F1 Attached is the beginning of an article Your task is to write the results section by
1 making up and reporting plausible descriptive statistics that will help the
reader understand the results of the statistical tests you report and the nature of your
sample (Hint this can be presented in the form of a table)
2 describing and defending your choice of appropriate statistical tests of the
hypotheses and the steps that you would go through in carrying out these tests
3 making up and reporting results of these tests that are consistent with your
descriptive statistics and with any information in the rest of the article about the
results found (Hint this can be presented in the form of a table)
4 describing how well these results provide support for the hypotheses You
may want to note any relevant threats to validity here
Be sure to state any assumptions you make
F2 Assume that the Personnel Manager of a local firm Ms B dFlandres hired you to
analyze some data that her assistants had collected over the past several years The
data consist of (a) job performance ratings that were made in June of 1990 and (b)
scores on 25 predictor variables (eg measures of education job experience job
tenure job aptitude personality) that were measured when the individuals were hired
(between April 1987 and May 1988) She had data from only the 110 subjects (60
males and 50 females) who were hired during the period and were still employed by
the firm One objective of your analysis (analyses) is to determine how well the
performance criterion can be predicted by the predictors What strategy would you
use in analyzing the data Describeexplain (b) Is sample size an issue for your
analyses Explain If it is what will you do to deal with problems stemming from
sample size Assume that no additional data can be collected at this time (c) Some
preliminary analyses that you do reveal that five of the predictor variables correlate
(zero-order basis) about 75 with one another Will this influence the analyses that
you use Will it influence the validity of conclusions derived from your proposed
analyses (d) Ms dFlandres is interested in knowing if the predictor variables are
equally effective in predicting the job success of males and females What analysis
or analyses would you do to deal with this issue
F3 Assume that you have been provided with data on 12 conceptually distinct variables
that are moderately correlated with one another at the empirical level The data are
from students in four different college majors ie astronomy (A) biology (B)
criminology (C) and demography (D) The 12 measured variables fall into the
general categories of mental health (tension emotional withdrawal hallucinations
guilt feelings blunted affect and suspiciousness) and job satisfaction (work itself
supervision co-workers pay promotion prospects and working conditions) Your
task is to determine if the individuals in the four college majors differ from one
another on the 12 measured variables
(a) What statistical technique(s) would you use to test for group differences
Explain Be specific about the procedures(s) that you would use
(b) What statistical estimate would you use to estimate the extent to which the
groups differ from one another Be specific
F4 The following statistical table published in a recent issue of Work amp Occupations
was taken from an article discussing variables influencing resistance and citizenship
behaviors in the workplace Resistance behaviors include playing dumb withholding
effort work avoidance subverting particular managers and sabotage Citizenship
behaviors include cooperation engaging in peer training use of insider knowledge to
facilitate production commitment to organizational goals giving extra effort freely
Both measures are global constructs aggregated to the interval level and
standardized
The table reports the results of a series of ordinary least squares regression equations
with standardized coefficients Explain the meaning of the statistics presented What
do these statistics tell us generally about the relationship between resistance
behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows
Anomie Index -standardized interval level measure tapping multiple dimensions
The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)
F5 Researchers collected data from a sample of 350 companies on the following
variables
size (measured as number of employees)
Business Strategy (a nominal variable with 2 response options low-cost provider or
differentiator)
HR Strategy (a nominal variable with 2 response categories High commitment or
low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

interaction What if anything would you do with the sum of squares for the
interaction effect
I2 A study examined the effects of gender and pre-training motivation on the transfer of

O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in

Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression
O6 The basic factor analysis model can be represented by the matrix algebraic
equation A B = C
(1) What do each of these matrices represent Be specific as to the type of
information in each matrix and its purpose
(2) For what purpose do researchers use factor analysis Explain In the process
provide a very brief description of a study for which factor analysis would be a
useful data analytic technique
O7 Factor analysis is an important statistical technique in organizational research
Describe factor analysis as an analytical tool including the following issues
a the reasons for using factor analysis
b the type of data necessary for using the technique appropriately
c the type of quantitative output that results from applying the technique
d how a researcher would use the output in his or her research
e how confirmatory factor analysis is different from exploratory
f the important issues and problems in using the technique
P) Structural Equation Models
P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)
Please comment on these restrictions versus access argument Which side do you
take
What are the strengths of SEM Give some examples
What are the weaknesses of SEM Give some examples

A2 Please evaluate the internal external construct and statistical conclusion validity of
[some recent article] Provide an argument given the current state of the literature
on this topic for which validity (or set of validities) is most critical at this juncture
in the field Finally given your critique and assessment design a follow-up study
that improves upon the key validity (or validities)
5 MEASUREMENT
A) Measurement Terms
A1 There are four levels of measurement rigor in management research Discuss each
one What properties do measurements at each level have (ie how much
information do the numbers from each level of measurement convey) How can the
numbers be changed (transformed) and still retain the properties of their
measurement level Pick one construct from a favorite research domain and give an
example of an operationalization of that construct at each of the four levels of
measurement rigor (provide arguments about why you think those examples reflect
each level) Lastly treat each examplelevel as a dependent variable in some
statistical analysis Given an example of a statistical technique appropriate for
analyzing data at that level of measurement rigor
A2 Define (and discuss important features or issues concerning) the following
constructs measurement (Define any six terms)
1 Construct validity 6 Item analysis
2 Likert scaling 7 Semantic differential
3 Cronbachs alpha 8 True score
4 Unobtrusive (trace) measurement 9 Generalizability theory
5 Interval scale 10 Criterion-related validity
11 Sociometric choice measures
B) Operationalization
B1 a) You are conducting a study which requires you to measure Hong Kong real
estate agents self-assessment of performance Since there is no existing
measurement available you have to develop the instrument by yourself
Describe how you would develop the measurement assuming that you have no
idea of how many dimension the construct has
b) Suppose you have developed an instrument consists of 20 questions
measuring 4 dimensions (5 items per dimension) from (a) You collected data
from another 300 real estate agents to validate your instrument Explain how
TH
you would use structural equations model (SEM) to examine the reliability and
validity of the instrument What are other concerns about reliability and validity
that are not addressed by this approach
B2 The research and business world have been fascinated with the concept of
organizational culture However operationalizing this construct has been a
difficult task Discuss the ways in which the construct has been operationalized
(eg technique static v dynamic sample selection generalizability) Critically
analyze each of these methodologies Then choose a methodology you would
use to examine organizational culture and defend your choice Describe how
you would study culture and what more would be known about culture as a
result of your study
B3 Suppose you are setting out to develop a new measure of a construct You want
this measure to be used in survey research and you want to establish its validity
and reliability Your goal is to have at the end of the process a measure that is
defensible and likely to be widely accepted by other researchers studying that
construct What steps would you take to conduct such a program of research
For each step explain the purpose of that step explain why that step is
important explain what methods and statistical procedures you would employ at
each step and explain what evidence you would hope to gather at each step
B4 Assume you are interested in constructing a new measure of (fill in with a
relevant variable from your field) Detail the major concerns that need to be
addressed and the steps that need to be taken in working toward validating this
new measure
B5 Assume that you recently read an article on workplace violence which you
found very interesting The authors argued that one of the predictors of
workplace violence was a construct called propensity to be violent and used a
one-item measure as follows How likely are you to become violent when
provoked You had serious doubts about the authors measure and decided to
develop your own
(a) How would you go about developing items to measure propensity to be
violent
(b) How would you determine whether the instrument was reliable
How would you determine whether the instrument was valid
B6 A concern in organizations is retirement of baby boomers within the next 5 -
10 years This concern is focused on the loss of older employees with skills
critical to the core business functions of organizations In order to continue to
have employees with those critical skills it seems necessary to retrain some
older workers However past practice in most organizations has been not to
retrain older workers for a variety of reasons mostly financial A researcher
working for the Human Resources Department of a large corporation - 13500
employees in 12 different plant locations - hypothesizes that the major reason
for not retraining older workers is ingrained in the culture of the corporation
IC
The researcher feels that older workers are not as highly valued as younger
workers in terms of their potential usefulness after retraining The researcher
searched the literature but found nothing in the existing literature to measure
the cultural value construct What should the researcher do to establish a reliable
and valid self-administered paper and pencil measure of this construct namely
the value of retraining older workers
a Please describe and explain the steps in temporal order that the researcher
must follow to develop a measure
b How would you evaluate the measure based on the technical requirements of
reliable and valid measurement as well as any practical issues in using the
measure considering the size of the employee population
B7 Assume that you are going to conduct empirical research to assess the role that
the complexity of an organizations manufacturing technology plays in
determining the level of centrality of decision making in the organization
Describe and justify the steps you might follow to develop an operationalization
of the concept of technological complexity What standards would you use to
determine if your operationalization is valid
B8 Organizational researchers have several strategies available to them for
gathering information (eg self-report measures archival measures direct
observation and trace measures) Assume that you are going to conduct
empirical research to assess the role that the structure of the organization plays
in determining the level of organizational effectiveness Briefly review the
strengths and weaknesses of the basic strategies (that is self-report measures
archival measures direct observation and trace measures) for measuring
organizational effectiveness Next describe and justify the steps you would
take to develop an operationalization of the concept of organizational
effectiveness What standards and procedures would you use to determine if
your operationalization is valid
B9 One of the most important topics of recent research has been stress in the work
place One of the most important problems with understanding this literature is
the varying definitions and measurement of this construct Suppose you had
decided to investigate the relationship between stress at the work place and dual
career family happiness
a Since there are multiple ways to measure stress in the work place describe
two ways to do this Hint - avoid using two self-report measures
b Describe how you would decide on the best single measure In doing so
describe the steps you would take in evaluating your measure Be sure to define
your meaning of validity and reliability It is important that your measure have
all the necessary psychometric characteristics so that other scientist can trust the
results of your research
c Be certain that you answer the question Validity for what
d In order to understand the results of your study you need to compare your
measure of stress at work with other measures of this construct How would you
do that
B10 Assume that you have been hired by a national survey research company
Shash Inc to write items that will be used in a national survey of attitudes
toward capital punishment There are a number of criteria that can be used to
guide your item writing What are they Briefly describe five (5) such criteria
B11 Assume that you are going to conduct empirical research to determine the
impact of interpersonal trust on organizational decision making Describe and
justify the steps you might follow to develop an operationalization of the
interpersonal trust concept
B12 Assume that you are going to conduct empirical field research to assess the role
that employee empowerment plays in determining the level of organizational
commitment of employees Describe and justifyexplain the steps you would
follow to develop a valid and reliable operationalization of the concept of
employee empowerment
Explain the procedures and standards you would use to determine if your
operationalization is valid and reliable
How would you assess the construct validity of such a measure
Discuss issues concerning the level of observation of your measure and level of
analysis of the data
B13 Assume you are interested in developing a new scale to measure construct X
Further assume that you have used previous literature and your own conceptual
development to delineate 2 dimensions of X specifically XF1 and XF2
Describe the steps you would go through in developing testing and evaluating
this new scale With regard to testing and evaluating be sure to consider the
role of factor analysis (both exploratory and confirmatory) and item analysis
Also you will want to make sure that your new multidimensional scale shows
evidence of validity (several kinds) and reliability so be sure to examine these
issues and explain how specific information gathered from the above testing
contributes to these concerns
C) Reliability
4) What is reliability and why is it so important What are the different ways reliability can be
assessed and when is each appropriate
15) What does coefficient alpha assess What are the ways coefficient alpha can be increased
C1 Describe and discuss the concept of reliability and all of its various forms
including their assessment When is each form appropriate and what information
is provided by each index
C2 In establishing congruence between multiple measurements we often compute
indices of reliability andor indices of agreement These two types of indices
address very different questions Your task is to 1) Define reliability and
agreement 2) Explain when each is useful using examples in which one but not
the other is appropriate and 3) Briefly describe two reliability indices and two
agreement indices
C3 Explain reliability in terms of the classical test theory What are the
consequences of unreliable measures in hypothesis testing What are the factors
that may affect the reliability of a multi-item scale

conceptualizations of error to determine reliability What are the implications of
using classical test theory versus generalizability theory to assess reliability
C5 In establishing congruence between measurements we often compute indices of
reliability andor agreement Define reliability and agreement Explain the
differences in reliability and agreement and describe under what conditions
assessing reliability is more appropriate and under what conditions assessing
agreement is more appropriate

true test score theory domain sampling theory generalizability theory IRT)
Discuss the different approaches for estimating reliability and the contexts in
which each might be appropriate Use examples throughout
C7 What are the consequences of unreliability in a measure
C8 What are some of the conditions that might keep the internal consistency (eg
alpha) of a given measure low Is a low alpha always a sign of a problematic
measure
C9 Define reliability Name some methods of calculating reliability How well do
these methods map up with the definition of reliability What is the impact of the
number of test items and sample size on Chronbachs alpha and why would this
effect occur or not occur (Note Do NOT discuss inter-rater reliability)
C10 Schmidt and Hunter (1996) described several types of measures typically used in
organizational research and identified the type(s) of measurement error affecting
each of them in various situations For each measure below indicate the types of
error and sources of error that are most likely to affect it Then indicate what
could be done to reduce errors of measurement andor what can be done to
control for errors statistically
a Supervisor ratings of subordinates job performance
b Self-ratings of ones own job performance
c Self-reports of ones own job-related attitudes
d Sales figures for a salesperson (or production quantity for a production
worker)
d Aptitude tests taken as part of the hiring process
C11 Suppose you had conducted research on the relationship between organizational
commitment and rigidity of organizational structure in 200 firms Your measure
of rigidity was based on number of organizational authority levels and the degree
to which written organizational rules existed and defined role behaviors for
employees Thus an organization with a large number of organizational levels
and specific written policies defining appropriate role behaviors for employees
would score high on rigidity of organizational structure After analyzing your
data you find that there is a statistically significant negative correlation between
commitment and rigidity which is consistent with your hypothesis However the
reliabilities for your two measures are
(1) commitment = 23 (2) rigidity = 83
How should you interpret your results What could you do to fix this situation
Describe the specific steps (in order) you would follow to develop a more
reliable measure of commitment
C12 (a) Define the concept of reliability (of measures) in a clear concise and
accurate manner (b) Provide a formula that expresses the reliability of a measure
in terms of two components of variance ie total variance and the error
variance
D) Multi-level Assessment
D1 One of the major challenges for group-level research is the issue of aggregation of
individual data to the group level

interrater agreement and reliability methods be used (Rwg Kappa and Weighted
Kappa percent agreement average pairwise correlation ANOVA methods
(interclass correlation coefficient WABA)) What are the advantages and
disadvantages of each of the methods
(b) Explain the controversy between Frank Schmidt Larry James and others
regarding the differences between interrater agreement and interrater reliability
Who is right Do the differences matter in research practice
Defend your answers
(c) Review two articles from the organizational behavior literature that have had to
deal with aggregation issues Critique the methods the authors used to make
aggregation decisions
(d) Provide some advice to researchers regarding what they should do if interrater
agreement and reliability indices indicate that it is not legitimate to aggregate their
data
(e) Provide some ideas for avoiding the need to aggregate in group-level research
through creative research methods and measurement strategies
D2 Cross-levelmulti-level research is becoming more evident in the organizational
research literature This type of research raises many issues and presents many
challenges in terms of designing the research measuring variables and collecting
and analyzing the data Assume that you are interested in aggregating data (eg
from the individual to the group or from the firm to the industry) for one or more
variables What are the major issues you will need to deal with
D3 A researcher wants to measure organizational climate for continuous learning
Organizational climate is operationalized as a shared consensual aspect of the
organization -- the shared perception among employees that the organization values
and supports continuous learning Describe how you would measure organizational
climate in this case Specify (a) the level (ie individual group organization) at
which the construct exists (b) the level at which you would measure the construct
and (c) the procedures that you would use to establish that measurement is aligned
with theory (ie the construct validity of the measure)
E) General (Measurement)
E1 Studies in organizational behavior research often rely on single-item measures of
key constructs The use of single-item measures has long been criticized based
on the premise that single-item measures are unreliable However Wanous
(Wanous amp Hudy 2001 Wanous amp Reichers 1996 Wanous Reichers amp Hudy
1997) has recently argued that single-item measures can exhibit adequate
reliability Wanous based this conclusion on a procedure for estimating the
reliability of single-item measures using the classic formula for correction for
attenuation Subsequent studies have yielded mixed results regarding the
conclusions of Wanous (eg Loo amp Kells 1998 Nagy 2002) and the veracity
of the perspective advocated by Wanous remains in question Summarize and
assess the arguments for and against the use of single-item measures and
evaluate the procedure and evidence offered by Wanous regarding the reliability
of single-item measures Based on your assessment and evaluation develop
recommendations regarding the use of single-item measures in organizational
behavior research

E2 Ipsative measures have become prevalent in organizational behavior research
Ipsative measures ask respondents to answer questions relative to one another
such that the scores for all questions sum to the same constant for all respondents
Examples of ipsative measures include rankings Q-sorts and the allocation of a
fixed number of points (eg 100) across a set of response options Ipsative
measures may be contrasted with absolute measures which ask respondents to
answer questions independently from one another Absolute measures are
exemplified by rating scales using an interval or ratio numeric response format
The relative merits of ipsative and absolute measures have been debated for
decades (eg Cornwell amp Dunlap 1994 Hicks 1970 Johnson Wood amp
Blinkhorn 1988 Saville amp Wilson 1991 1992) yet the fundamental issues
underlying this debate have not been adequately addressed in organizational
behavior research For example measures of organizational culture and values
are often ipsative and some researchers advocate these measures over absolute
measures (eg Meglino amp Ravlin 1987 OReilly Chatman amp Caldwell 1991
Ravlin amp Meglino 1987 see also Rokeach amp Ball-Rokeach 1989) Review the
relative merits of absolute and ipsative measures Based on your review which
form of measurement is most appropriate and why Do your conclusions depend
on the construct being measured If so what types of constructs are best suited to
ipsative measures and what types are best suited to absolute measures Next
apply your conclusions to the measurement of culture and values in
organizations What specific arguments have been advanced in favor of ipsative
measures of culture and values How sound are these arguments Should ipsative
measures be used in the study of organizational culture and values If not how
can absolute measures of culture and values be developed that address the
concerns voiced by advocates of ipsative measures Provide a specific example
of the type of measure you would propose

facets of a concept Although such measures are prevalent and in some cases are
advocated (eg Law et al 1998 1999) they can present a variety of conceptual
and methodological problems Describe the specific problems associated with

E5 Suppose Roberta Von Eisenbrick is a researcher interested in the consequences of
AFFECTIVE CONFLICT (AC) in decision-making teams She gets access to a
variety of outcomes assessment committees at each of 87 different schools in
the Dallas Independent School District and gains permission to tape-record two
of their meetings (one in February and one in March) Such committees have
been formed to develop quantitative ways to track pursuit of school goals and
provide accountability to local and state governments These are often divisive
teams with heated meetings because what gets assessed is what usually gets
rewarded After both of these meetings the committee members each
fill out a short questionnaire that contains 20 Likert-type items measuring how
much AC occurred (eg People in our group often get angry with each other)
The individual scores are summed across items then averaged across team
members to come up with a group-level AC score for each of the 87 2
meetings The same procedures are followed for a 5-item measure of Group
Cohesiveness (GC) which is predicted to be reduced by higher levels of AC
Roberta also listens to every tape and from her expert judgment she rates each
groups meetings on the same 20 items Those 20 ratings are summed for each of
the 87 2 meetings Now Roberta is interested in evaluating her measure She
wants it to have excellent psychometric properties including reliability and
construct validity

it
c What is construct validity Discuss how the (un)reliability of the AC measure
could affect the conclusions one would draw from a study involving it and GC In

B2 In recent years (and in not so recent years for that matter) methodologists have
criticized the fact that psychologists rely heavily on significance testing What
are the essential elements of these critiques What are some remedies to the
problems engendered by significance testing and why have these remedies not
been widely adopted
B3 (a) There is a debate among the IndustrialOrganizational psychologists on
whether we should abandon significance testing and report confidence intervals
instead Please summarize arguments from both sides and state your position on
this issue
(b) From time to time some researchers want to confirm null hypotheses in their
studies What are the concerns of accepting a null hypothesis What precautions
we can do to provide a stronger support for a null hypothesis

each relates to main effects (c) Using variables of your choice please write
hypotheses to reflect both (d) Explain how each is tested analytically
D2 Discuss moderators and mediators Provide an example of how (1) a moderating
variable influences the relationship between the independent and dependent
variable and how (2) a mediating variable influences the relationship between
the independent and dependent variable Describe how you would test for both
moderation and mediation using regression
D3 Many theories in organizational research predict that the effects of one variable
on another are moderated by a third variable Such moderator effects are
typically tested by entering the product of two variables as a predictor after
controlling for the two variables that constitute the product Several researchers
have pointed out that this product is often highly correlated with the squares of
the two constituent variables and have suggested that moderating effects may be
tested after controlling not only for the two constituent variables but also their
squares (eg Cortina 1993 Ganzach 1998 Lubinski amp Humphreys 1990
MacCallum amp Mar 1995) Discuss the strengths and weaknesses of this
approach as compared to methods that use only the product term and its
constituent variables Conclude with recommendations as to when and under
what conditions organizational researchers should test moderator effects with the
squares of the constituent variables in the equation

D4 Assume you are interested in studying relationships amongst three variables X
Y and Z Your first hypothesis posits Z as a mediator of the relationship between
X and Y Your second hypothesis posits Z as a moderator of the relationship
between X and Y Draw the figures depicting each of these hypothesized
relationships and describe (make sure to write regression equations) how you
would test each of these hypotheses
D5 The amount of time and effort that the average person pours into his or her job
has risen steadily over the last two decades such that the average person now is
working one more week per year than the average person in the mid 1970s This
steady increase has fueled research interest in the construct of Job Burnout (JB)
which is an emotional and physical exhaustion associated with ones work
Organizational Stress (OS) the perception of greater demands than available
resources in ones work environment is thought to be one of the chief
antecedents of JB However time spent under OS is thought to make its affects
on JB accumulate or worsen Work Role Withdrawal (WRW) the avoidance of
responsibilities or the deliberate reduction of inputs to ones job is believed to be
the chief consequence of JB
a Formally state these ideas as verbal hypotheses as equations and as a complex
directed graph (circle amp arrow diagram)
b Conceptually what is a mediator Define the term and identify the mediator in
your hypotheses in (a) What elements or steps in a study design (not statistics)
that would be helpful for detecting the mediating relationship that was proposed

subdomains of management Further demonstrate your understanding of
moderator variables by picking which variable in (a) is the moderator Show the
moderating relationship in an X-Y (or multi-layered) chart Again what elements

student about the appropriate use of multiple comparisons and post hoc tests in
analysis of variance Your student colleague already has been introduced to ANOVA
and multiple regression Specifically you are to write out a description of how to test
for differences among the different levels or cells of a categorical variable In your
description you should discuss among other things
a the statistical and philosophical issues raised by post hoc analysis and data
snooping

for differences among cell means and
c the advantages and disadvantages of each method
Note Your written description will be evaluated based on your demonstrated
competence with the statistical method not on the pedagogy of your explanation
F) Applied Data Analysis
16) Q Your departmental chair is considering a new textbook and has asked for your
recommendations You conduct a well-designed controlled study (details are unimportant) and discover students who use the new book perform 10 better on a standardized subject
matter exam than those using the old book (p = 027) Both books are readily availabe their prices are almost identical and both are equally acceptable to the instructors What is your recommendation to the chair
F1 Attached is the beginning of an article Your task is to write the results section by
1 making up and reporting plausible descriptive statistics that will help the
reader understand the results of the statistical tests you report and the nature of your
sample (Hint this can be presented in the form of a table)
2 describing and defending your choice of appropriate statistical tests of the
hypotheses and the steps that you would go through in carrying out these tests
3 making up and reporting results of these tests that are consistent with your
descriptive statistics and with any information in the rest of the article about the
results found (Hint this can be presented in the form of a table)
4 describing how well these results provide support for the hypotheses You
may want to note any relevant threats to validity here
Be sure to state any assumptions you make
F2 Assume that the Personnel Manager of a local firm Ms B dFlandres hired you to
analyze some data that her assistants had collected over the past several years The
data consist of (a) job performance ratings that were made in June of 1990 and (b)
scores on 25 predictor variables (eg measures of education job experience job
tenure job aptitude personality) that were measured when the individuals were hired
(between April 1987 and May 1988) She had data from only the 110 subjects (60
males and 50 females) who were hired during the period and were still employed by
the firm One objective of your analysis (analyses) is to determine how well the
performance criterion can be predicted by the predictors What strategy would you
use in analyzing the data Describeexplain (b) Is sample size an issue for your
analyses Explain If it is what will you do to deal with problems stemming from
sample size Assume that no additional data can be collected at this time (c) Some
preliminary analyses that you do reveal that five of the predictor variables correlate
(zero-order basis) about 75 with one another Will this influence the analyses that
you use Will it influence the validity of conclusions derived from your proposed
analyses (d) Ms dFlandres is interested in knowing if the predictor variables are
equally effective in predicting the job success of males and females What analysis
or analyses would you do to deal with this issue
F3 Assume that you have been provided with data on 12 conceptually distinct variables
that are moderately correlated with one another at the empirical level The data are
from students in four different college majors ie astronomy (A) biology (B)
criminology (C) and demography (D) The 12 measured variables fall into the
general categories of mental health (tension emotional withdrawal hallucinations
guilt feelings blunted affect and suspiciousness) and job satisfaction (work itself
supervision co-workers pay promotion prospects and working conditions) Your
task is to determine if the individuals in the four college majors differ from one
another on the 12 measured variables
(a) What statistical technique(s) would you use to test for group differences
Explain Be specific about the procedures(s) that you would use
(b) What statistical estimate would you use to estimate the extent to which the
groups differ from one another Be specific
F4 The following statistical table published in a recent issue of Work amp Occupations
was taken from an article discussing variables influencing resistance and citizenship
behaviors in the workplace Resistance behaviors include playing dumb withholding
effort work avoidance subverting particular managers and sabotage Citizenship
behaviors include cooperation engaging in peer training use of insider knowledge to
facilitate production commitment to organizational goals giving extra effort freely
Both measures are global constructs aggregated to the interval level and
standardized
The table reports the results of a series of ordinary least squares regression equations
with standardized coefficients Explain the meaning of the statistics presented What
do these statistics tell us generally about the relationship between resistance
behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows
Anomie Index -standardized interval level measure tapping multiple dimensions
The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)
F5 Researchers collected data from a sample of 350 companies on the following
variables
size (measured as number of employees)
Business Strategy (a nominal variable with 2 response options low-cost provider or
differentiator)
HR Strategy (a nominal variable with 2 response categories High commitment or
low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

I2 A study examined the effects of gender and pre-training motivation on the transfer of
training in terms of improved performance for 123 new industrial managers The
training was on supervisory skills and the dependent variable was based on the

as you see it within the time span of your career as an academic To do this use
examples of already written (or yet to be written) articles as models
J5 A frequent criticism of non-quantitative research summaries (literature reviews) is

affected the statistical outcomes of the studies included in the literature review Meta-
analysis however allows one to statistically examine such effects Assume you are
conducting a meta-analysis of the relationship between leader behaviors and group
productivity Briefly describe the steps you would take in conducting a meta-

O4 Describe the differences between exploratory factor analysis (EFA) and
confirmatory factor analysis (CFA) When would you use one verses another
Are there ways to use EFA in a confirmatory way Can you use CFA in an
exploratory way Also describe the difference in principal components analysis
(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression
O6 The basic factor analysis model can be represented by the matrix algebraic
equation A B = C

information in each matrix and its purpose
(2) For what purpose do researchers use factor analysis Explain In the process
provide a very brief description of a study for which factor analysis would be a
useful data analytic technique
O7 Factor analysis is an important statistical technique in organizational research
Describe factor analysis as an analytical tool including the following issues
a the reasons for using factor analysis

c the type of quantitative output that results from applying the technique
d how a researcher would use the output in his or her research

f the important issues and problems in using the technique
P) Structural Equation Models
P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)
Please comment on these restrictions versus access argument Which side do you
take
What are the strengths of SEM Give some examples
What are the weaknesses of SEM Give some examples

you would use structural equations model (SEM) to examine the reliability and
validity of the instrument What are other concerns about reliability and validity
that are not addressed by this approach
B2 The research and business world have been fascinated with the concept of
organizational culture However operationalizing this construct has been a
difficult task Discuss the ways in which the construct has been operationalized
(eg technique static v dynamic sample selection generalizability) Critically
analyze each of these methodologies Then choose a methodology you would
use to examine organizational culture and defend your choice Describe how
you would study culture and what more would be known about culture as a
result of your study
B3 Suppose you are setting out to develop a new measure of a construct You want
this measure to be used in survey research and you want to establish its validity
and reliability Your goal is to have at the end of the process a measure that is
defensible and likely to be widely accepted by other researchers studying that
construct What steps would you take to conduct such a program of research
For each step explain the purpose of that step explain why that step is
important explain what methods and statistical procedures you would employ at
each step and explain what evidence you would hope to gather at each step
B4 Assume you are interested in constructing a new measure of (fill in with a
relevant variable from your field) Detail the major concerns that need to be
addressed and the steps that need to be taken in working toward validating this
new measure
B5 Assume that you recently read an article on workplace violence which you
found very interesting The authors argued that one of the predictors of
workplace violence was a construct called propensity to be violent and used a
one-item measure as follows How likely are you to become violent when
provoked You had serious doubts about the authors measure and decided to
develop your own
(a) How would you go about developing items to measure propensity to be
violent
(b) How would you determine whether the instrument was reliable
How would you determine whether the instrument was valid
B6 A concern in organizations is retirement of baby boomers within the next 5 -
10 years This concern is focused on the loss of older employees with skills
critical to the core business functions of organizations In order to continue to
have employees with those critical skills it seems necessary to retrain some
older workers However past practice in most organizations has been not to
retrain older workers for a variety of reasons mostly financial A researcher
working for the Human Resources Department of a large corporation - 13500
employees in 12 different plant locations - hypothesizes that the major reason
for not retraining older workers is ingrained in the culture of the corporation
IC
The researcher feels that older workers are not as highly valued as younger
workers in terms of their potential usefulness after retraining The researcher
searched the literature but found nothing in the existing literature to measure
the cultural value construct What should the researcher do to establish a reliable
and valid self-administered paper and pencil measure of this construct namely
the value of retraining older workers
a Please describe and explain the steps in temporal order that the researcher
must follow to develop a measure
b How would you evaluate the measure based on the technical requirements of
reliable and valid measurement as well as any practical issues in using the
measure considering the size of the employee population
B7 Assume that you are going to conduct empirical research to assess the role that
the complexity of an organizations manufacturing technology plays in
determining the level of centrality of decision making in the organization
Describe and justify the steps you might follow to develop an operationalization
of the concept of technological complexity What standards would you use to
determine if your operationalization is valid
B8 Organizational researchers have several strategies available to them for
gathering information (eg self-report measures archival measures direct
observation and trace measures) Assume that you are going to conduct
empirical research to assess the role that the structure of the organization plays
in determining the level of organizational effectiveness Briefly review the
strengths and weaknesses of the basic strategies (that is self-report measures
archival measures direct observation and trace measures) for measuring
organizational effectiveness Next describe and justify the steps you would
take to develop an operationalization of the concept of organizational
effectiveness What standards and procedures would you use to determine if
your operationalization is valid
B9 One of the most important topics of recent research has been stress in the work
place One of the most important problems with understanding this literature is

Describe the steps you would go through in developing testing and evaluating
this new scale With regard to testing and evaluating be sure to consider the
role of factor analysis (both exploratory and confirmatory) and item analysis
Also you will want to make sure that your new multidimensional scale shows
evidence of validity (several kinds) and reliability so be sure to examine these

including their assessment When is each form appropriate and what information
is provided by each index
C2 In establishing congruence between multiple measurements we often compute
indices of reliability andor indices of agreement These two types of indices
address very different questions Your task is to 1) Define reliability and

C10 Schmidt and Hunter (1996) described several types of measures typically used in
organizational research and identified the type(s) of measurement error affecting
each of them in various situations For each measure below indicate the types of
error and sources of error that are most likely to affect it Then indicate what
could be done to reduce errors of measurement andor what can be done to
control for errors statistically

worker)
d Aptitude tests taken as part of the hiring process
C11 Suppose you had conducted research on the relationship between organizational
commitment and rigidity of organizational structure in 200 firms Your measure
of rigidity was based on number of organizational authority levels and the degree
to which written organizational rules existed and defined role behaviors for
employees Thus an organization with a large number of organizational levels
and specific written policies defining appropriate role behaviors for employees
would score high on rigidity of organizational structure After analyzing your
data you find that there is a statistically significant negative correlation between
commitment and rigidity which is consistent with your hypothesis However the
reliabilities for your two measures are
(1) commitment = 23 (2) rigidity = 83
How should you interpret your results What could you do to fix this situation
Describe the specific steps (in order) you would follow to develop a more
reliable measure of commitment
C12 (a) Define the concept of reliability (of measures) in a clear concise and
accurate manner (b) Provide a formula that expresses the reliability of a measure

research literature This type of research raises many issues and presents many
challenges in terms of designing the research measuring variables and collecting
and analyzing the data Assume that you are interested in aggregating data (eg
from the individual to the group or from the firm to the industry) for one or more
variables What are the major issues you will need to deal with
D3 A researcher wants to measure organizational climate for continuous learning
Organizational climate is operationalized as a shared consensual aspect of the
organization -- the shared perception among employees that the organization values
and supports continuous learning Describe how you would measure organizational
climate in this case Specify (a) the level (ie individual group organization) at
which the construct exists (b) the level at which you would measure the construct
and (c) the procedures that you would use to establish that measurement is aligned
with theory (ie the construct validity of the measure)
E) General (Measurement)
E1 Studies in organizational behavior research often rely on single-item measures of
key constructs The use of single-item measures has long been criticized based
on the premise that single-item measures are unreliable However Wanous
(Wanous amp Hudy 2001 Wanous amp Reichers 1996 Wanous Reichers amp Hudy
1997) has recently argued that single-item measures can exhibit adequate
reliability Wanous based this conclusion on a procedure for estimating the
reliability of single-item measures using the classic formula for correction for
attenuation Subsequent studies have yielded mixed results regarding the
conclusions of Wanous (eg Loo amp Kells 1998 Nagy 2002) and the veracity
of the perspective advocated by Wanous remains in question Summarize and
assess the arguments for and against the use of single-item measures and
evaluate the procedure and evidence offered by Wanous regarding the reliability
of single-item measures Based on your assessment and evaluation develop
recommendations regarding the use of single-item measures in organizational
behavior research

E2 Ipsative measures have become prevalent in organizational behavior research
Ipsative measures ask respondents to answer questions relative to one another
such that the scores for all questions sum to the same constant for all respondents
Examples of ipsative measures include rankings Q-sorts and the allocation of a
fixed number of points (eg 100) across a set of response options Ipsative
measures may be contrasted with absolute measures which ask respondents to
answer questions independently from one another Absolute measures are
exemplified by rating scales using an interval or ratio numeric response format
The relative merits of ipsative and absolute measures have been debated for
decades (eg Cornwell amp Dunlap 1994 Hicks 1970 Johnson Wood amp
Blinkhorn 1988 Saville amp Wilson 1991 1992) yet the fundamental issues
underlying this debate have not been adequately addressed in organizational
behavior research For example measures of organizational culture and values
are often ipsative and some researchers advocate these measures over absolute
measures (eg Meglino amp Ravlin 1987 OReilly Chatman amp Caldwell 1991
Ravlin amp Meglino 1987 see also Rokeach amp Ball-Rokeach 1989) Review the
relative merits of absolute and ipsative measures Based on your review which
form of measurement is most appropriate and why Do your conclusions depend
on the construct being measured If so what types of constructs are best suited to
ipsative measures and what types are best suited to absolute measures Next
apply your conclusions to the measurement of culture and values in
organizations What specific arguments have been advanced in favor of ipsative
measures of culture and values How sound are these arguments Should ipsative
measures be used in the study of organizational culture and values If not how
can absolute measures of culture and values be developed that address the
concerns voiced by advocates of ipsative measures Provide a specific example
of the type of measure you would propose

facets of a concept Although such measures are prevalent and in some cases are

and methodological problems Describe the specific problems associated with
measures that use items representing different facets of a concept Compare these
problems with the purported advantages of such measures Conclude by

E5 Suppose Roberta Von Eisenbrick is a researcher interested in the consequences of
AFFECTIVE CONFLICT (AC) in decision-making teams She gets access to a
variety of outcomes assessment committees at each of 87 different schools in
the Dallas Independent School District and gains permission to tape-record two
of their meetings (one in February and one in March) Such committees have
been formed to develop quantitative ways to track pursuit of school goals and
provide accountability to local and state governments These are often divisive
teams with heated meetings because what gets assessed is what usually gets
rewarded After both of these meetings the committee members each
fill out a short questionnaire that contains 20 Likert-type items measuring how
much AC occurred (eg People in our group often get angry with each other)
The individual scores are summed across items then averaged across team
members to come up with a group-level AC score for each of the 87 2
meetings The same procedures are followed for a 5-item measure of Group
Cohesiveness (GC) which is predicted to be reduced by higher levels of AC
Roberta also listens to every tape and from her expert judgment she rates each
groups meetings on the same 20 items Those 20 ratings are summed for each of
the 87 2 meetings Now Roberta is interested in evaluating her measure She
wants it to have excellent psychometric properties including reliability and
construct validity

D) ModeratorsMediators
D1 Moderation and mediation provide different ways to model third variable effects
(a) Please define both of these terms (b) Sketch a conceptual model to show how
each relates to main effects (c) Using variables of your choice please write
hypotheses to reflect both (d) Explain how each is tested analytically
D2 Discuss moderators and mediators Provide an example of how (1) a moderating
variable influences the relationship between the independent and dependent
variable and how (2) a mediating variable influences the relationship between
the independent and dependent variable Describe how you would test for both
moderation and mediation using regression
D3 Many theories in organizational research predict that the effects of one variable
on another are moderated by a third variable Such moderator effects are
typically tested by entering the product of two variables as a predictor after
controlling for the two variables that constitute the product Several researchers
have pointed out that this product is often highly correlated with the squares of
the two constituent variables and have suggested that moderating effects may be
tested after controlling not only for the two constituent variables but also their
squares (eg Cortina 1993 Ganzach 1998 Lubinski amp Humphreys 1990
MacCallum amp Mar 1995) Discuss the strengths and weaknesses of this
approach as compared to methods that use only the product term and its
constituent variables Conclude with recommendations as to when and under
what conditions organizational researchers should test moderator effects with the
squares of the constituent variables in the equation

D4 Assume you are interested in studying relationships amongst three variables X
Y and Z Your first hypothesis posits Z as a mediator of the relationship between
X and Y Your second hypothesis posits Z as a moderator of the relationship
between X and Y Draw the figures depicting each of these hypothesized
relationships and describe (make sure to write regression equations) how you
would test each of these hypotheses
D5 The amount of time and effort that the average person pours into his or her job
has risen steadily over the last two decades such that the average person now is
working one more week per year than the average person in the mid 1970s This
steady increase has fueled research interest in the construct of Job Burnout (JB)
which is an emotional and physical exhaustion associated with ones work
Organizational Stress (OS) the perception of greater demands than available
resources in ones work environment is thought to be one of the chief
antecedents of JB However time spent under OS is thought to make its affects
on JB accumulate or worsen Work Role Withdrawal (WRW) the avoidance of
responsibilities or the deliberate reduction of inputs to ones job is believed to be
the chief consequence of JB
a Formally state these ideas as verbal hypotheses as equations and as a complex
directed graph (circle amp arrow diagram)
b Conceptually what is a mediator Define the term and identify the mediator in
your hypotheses in (a) What elements or steps in a study design (not statistics)
that would be helpful for detecting the mediating relationship that was proposed

subdomains of management Further demonstrate your understanding of
moderator variables by picking which variable in (a) is the moderator Show the
moderating relationship in an X-Y (or multi-layered) chart Again what elements
or steps in a study design (not statistics) would be helpful for detecting the
moderating effect implied above

for differences among the different levels or cells of a categorical variable In your
description you should discuss among other things

recommendations You conduct a well-designed controlled study (details are unimportant) and discover students who use the new book perform 10 better on a standardized subject
matter exam than those using the old book (p = 027) Both books are readily availabe their prices are almost identical and both are equally acceptable to the instructors What is your recommendation to the chair
F1 Attached is the beginning of an article Your task is to write the results section by

reader understand the results of the statistical tests you report and the nature of your
sample (Hint this can be presented in the form of a table)
2 describing and defending your choice of appropriate statistical tests of the
hypotheses and the steps that you would go through in carrying out these tests
3 making up and reporting results of these tests that are consistent with your
descriptive statistics and with any information in the rest of the article about the
results found (Hint this can be presented in the form of a table)

may want to note any relevant threats to validity here
Be sure to state any assumptions you make
F2 Assume that the Personnel Manager of a local firm Ms B dFlandres hired you to
analyze some data that her assistants had collected over the past several years The
data consist of (a) job performance ratings that were made in June of 1990 and (b)
scores on 25 predictor variables (eg measures of education job experience job
tenure job aptitude personality) that were measured when the individuals were hired
(between April 1987 and May 1988) She had data from only the 110 subjects (60
males and 50 females) who were hired during the period and were still employed by
the firm One objective of your analysis (analyses) is to determine how well the
performance criterion can be predicted by the predictors What strategy would you
use in analyzing the data Describeexplain (b) Is sample size an issue for your
analyses Explain If it is what will you do to deal with problems stemming from
sample size Assume that no additional data can be collected at this time (c) Some
preliminary analyses that you do reveal that five of the predictor variables correlate
(zero-order basis) about 75 with one another Will this influence the analyses that
you use Will it influence the validity of conclusions derived from your proposed
analyses (d) Ms dFlandres is interested in knowing if the predictor variables are
equally effective in predicting the job success of males and females What analysis
or analyses would you do to deal with this issue
F3 Assume that you have been provided with data on 12 conceptually distinct variables
that are moderately correlated with one another at the empirical level The data are
from students in four different college majors ie astronomy (A) biology (B)
criminology (C) and demography (D) The 12 measured variables fall into the
general categories of mental health (tension emotional withdrawal hallucinations
guilt feelings blunted affect and suspiciousness) and job satisfaction (work itself
supervision co-workers pay promotion prospects and working conditions) Your
task is to determine if the individuals in the four college majors differ from one
another on the 12 measured variables

Explain Be specific about the procedures(s) that you would use
(b) What statistical estimate would you use to estimate the extent to which the
groups differ from one another Be specific
F4 The following statistical table published in a recent issue of Work amp Occupations
was taken from an article discussing variables influencing resistance and citizenship
behaviors in the workplace Resistance behaviors include playing dumb withholding
effort work avoidance subverting particular managers and sabotage Citizenship
behaviors include cooperation engaging in peer training use of insider knowledge to
facilitate production commitment to organizational goals giving extra effort freely
Both measures are global constructs aggregated to the interval level and
standardized
The table reports the results of a series of ordinary least squares regression equations
with standardized coefficients Explain the meaning of the statistics presented What
do these statistics tell us generally about the relationship between resistance
behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows
Anomie Index -standardized interval level measure tapping multiple dimensions
The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)
F5 Researchers collected data from a sample of 350 companies on the following
variables
size (measured as number of employees)
Business Strategy (a nominal variable with 2 response options low-cost provider or
differentiator)
HR Strategy (a nominal variable with 2 response categories High commitment or
low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

I2 A study examined the effects of gender and pre-training motivation on the transfer of
training in terms of improved performance for 123 new industrial managers The
training was on supervisory skills and the dependent variable was based on the
appraisal of the supervisors performance before the training and three months after
the training The performance appraisal data were collected for research purposes
only and resulted in a total transfer score from 1 to 25 with 1 being low Pre-training
motivation was based on a 12 item Likert scale with an alpha of 86 Two groups
were identified for the pre-training motivation variable - the bottom 13 (low) and the
top 13 (high) Table 1 contains the ANOVA results and Table 2 contains the cell

mirrors Explain both sides of the debate and then lay out the role of meta-analysis
as you see it within the time span of your career as an academic To do this use
examples of already written (or yet to be written) articles as models
J5 A frequent criticism of non-quantitative research summaries (literature reviews) is
that researchers do not carefully examine how particular research designs might have
affected the statistical outcomes of the studies included in the literature review Meta-
analysis however allows one to statistically examine such effects Assume you are
conducting a meta-analysis of the relationship between leader behaviors and group
productivity Briefly describe the steps you would take in conducting a meta-
analysis What aspects of the original research designs would you examine in your
meta-analysis What steps would you take in gathering and coding data to enhance

confirmatory factor analysis (CFA) When would you use one verses another
Are there ways to use EFA in a confirmatory way Can you use CFA in an
exploratory way Also describe the difference in principal components analysis
(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression

P) Structural Equation Models
P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)
Please comment on these restrictions versus access argument Which side do you
take
What are the strengths of SEM Give some examples
What are the weaknesses of SEM Give some examples

C10 Schmidt and Hunter (1996) described several types of measures typically used in
organizational research and identified the type(s) of measurement error affecting
each of them in various situations For each measure below indicate the types of
error and sources of error that are most likely to affect it Then indicate what

C11 Suppose you had conducted research on the relationship between organizational
commitment and rigidity of organizational structure in 200 firms Your measure
of rigidity was based on number of organizational authority levels and the degree
to which written organizational rules existed and defined role behaviors for
employees Thus an organization with a large number of organizational levels
and specific written policies defining appropriate role behaviors for employees
would score high on rigidity of organizational structure After analyzing your
data you find that there is a statistically significant negative correlation between
commitment and rigidity which is consistent with your hypothesis However the
reliabilities for your two measures are
(1) commitment = 23 (2) rigidity = 83
How should you interpret your results What could you do to fix this situation
Describe the specific steps (in order) you would follow to develop a more

research literature This type of research raises many issues and presents many
challenges in terms of designing the research measuring variables and collecting
and analyzing the data Assume that you are interested in aggregating data (eg
from the individual to the group or from the firm to the industry) for one or more
variables What are the major issues you will need to deal with
D3 A researcher wants to measure organizational climate for continuous learning
Organizational climate is operationalized as a shared consensual aspect of the
organization -- the shared perception among employees that the organization values
and supports continuous learning Describe how you would measure organizational
climate in this case Specify (a) the level (ie individual group organization) at
which the construct exists (b) the level at which you would measure the construct
and (c) the procedures that you would use to establish that measurement is aligned
with theory (ie the construct validity of the measure)
E) General (Measurement)
E1 Studies in organizational behavior research often rely on single-item measures of
key constructs The use of single-item measures has long been criticized based
on the premise that single-item measures are unreliable However Wanous
(Wanous amp Hudy 2001 Wanous amp Reichers 1996 Wanous Reichers amp Hudy
1997) has recently argued that single-item measures can exhibit adequate
reliability Wanous based this conclusion on a procedure for estimating the
reliability of single-item measures using the classic formula for correction for
attenuation Subsequent studies have yielded mixed results regarding the
conclusions of Wanous (eg Loo amp Kells 1998 Nagy 2002) and the veracity
of the perspective advocated by Wanous remains in question Summarize and
assess the arguments for and against the use of single-item measures and
evaluate the procedure and evidence offered by Wanous regarding the reliability
of single-item measures Based on your assessment and evaluation develop
recommendations regarding the use of single-item measures in organizational
behavior research

E2 Ipsative measures have become prevalent in organizational behavior research
Ipsative measures ask respondents to answer questions relative to one another
such that the scores for all questions sum to the same constant for all respondents
Examples of ipsative measures include rankings Q-sorts and the allocation of a
fixed number of points (eg 100) across a set of response options Ipsative
measures may be contrasted with absolute measures which ask respondents to
answer questions independently from one another Absolute measures are
exemplified by rating scales using an interval or ratio numeric response format
The relative merits of ipsative and absolute measures have been debated for
decades (eg Cornwell amp Dunlap 1994 Hicks 1970 Johnson Wood amp
Blinkhorn 1988 Saville amp Wilson 1991 1992) yet the fundamental issues
underlying this debate have not been adequately addressed in organizational
behavior research For example measures of organizational culture and values
are often ipsative and some researchers advocate these measures over absolute
measures (eg Meglino amp Ravlin 1987 OReilly Chatman amp Caldwell 1991
Ravlin amp Meglino 1987 see also Rokeach amp Ball-Rokeach 1989) Review the
relative merits of absolute and ipsative measures Based on your review which
form of measurement is most appropriate and why Do your conclusions depend
on the construct being measured If so what types of constructs are best suited to
ipsative measures and what types are best suited to absolute measures Next
apply your conclusions to the measurement of culture and values in
organizations What specific arguments have been advanced in favor of ipsative
measures of culture and values How sound are these arguments Should ipsative
measures be used in the study of organizational culture and values If not how
can absolute measures of culture and values be developed that address the
concerns voiced by advocates of ipsative measures Provide a specific example
of the type of measure you would propose

E5 Suppose Roberta Von Eisenbrick is a researcher interested in the consequences of
AFFECTIVE CONFLICT (AC) in decision-making teams She gets access to a
variety of outcomes assessment committees at each of 87 different schools in
the Dallas Independent School District and gains permission to tape-record two
of their meetings (one in February and one in March) Such committees have
been formed to develop quantitative ways to track pursuit of school goals and
provide accountability to local and state governments These are often divisive
teams with heated meetings because what gets assessed is what usually gets
rewarded After both of these meetings the committee members each
fill out a short questionnaire that contains 20 Likert-type items measuring how
much AC occurred (eg People in our group often get angry with each other)
The individual scores are summed across items then averaged across team
members to come up with a group-level AC score for each of the 87 2
meetings The same procedures are followed for a 5-item measure of Group
Cohesiveness (GC) which is predicted to be reduced by higher levels of AC
Roberta also listens to every tape and from her expert judgment she rates each
groups meetings on the same 20 items Those 20 ratings are summed for each of
the 87 2 meetings Now Roberta is interested in evaluating her measure She
wants it to have excellent psychometric properties including reliability and
construct validity

definition to the context given above
b How could you estimate the reliability of this new measure of AC Cover at
least three kinds of estimates and the sources of error each one assumes or is
estimating Pick one of those kinds of estimates and provide a rationale for using
it
c What is construct validity Discuss how the (un)reliability of the AC measure
could affect the conclusions one would draw from a study involving it and GC In

validity and the connection between reliability and the probability of Type I or
Type II statistical errors

are the essential elements of these critiques What are some remedies to the
problems engendered by significance testing and why have these remedies not
been widely adopted
B3 (a) There is a debate among the IndustrialOrganizational psychologists on

instead Please summarize arguments from both sides and state your position on
this issue
(b) From time to time some researchers want to confirm null hypotheses in their

things that researchers have inappropriately sanctified the p lt 05 level of
significance Describe and critique the arguments for and against the use of
statistical significance testing in empirical research What information other than

D) ModeratorsMediators
D1 Moderation and mediation provide different ways to model third variable effects
(a) Please define both of these terms (b) Sketch a conceptual model to show how
each relates to main effects (c) Using variables of your choice please write
hypotheses to reflect both (d) Explain how each is tested analytically
D2 Discuss moderators and mediators Provide an example of how (1) a moderating
variable influences the relationship between the independent and dependent
variable and how (2) a mediating variable influences the relationship between
the independent and dependent variable Describe how you would test for both
moderation and mediation using regression
D3 Many theories in organizational research predict that the effects of one variable
on another are moderated by a third variable Such moderator effects are
typically tested by entering the product of two variables as a predictor after
controlling for the two variables that constitute the product Several researchers
have pointed out that this product is often highly correlated with the squares of
the two constituent variables and have suggested that moderating effects may be
tested after controlling not only for the two constituent variables but also their
squares (eg Cortina 1993 Ganzach 1998 Lubinski amp Humphreys 1990
MacCallum amp Mar 1995) Discuss the strengths and weaknesses of this
approach as compared to methods that use only the product term and its
constituent variables Conclude with recommendations as to when and under
what conditions organizational researchers should test moderator effects with the
squares of the constituent variables in the equation

D4 Assume you are interested in studying relationships amongst three variables X
Y and Z Your first hypothesis posits Z as a mediator of the relationship between
X and Y Your second hypothesis posits Z as a moderator of the relationship
between X and Y Draw the figures depicting each of these hypothesized
relationships and describe (make sure to write regression equations) how you
would test each of these hypotheses
D5 The amount of time and effort that the average person pours into his or her job
has risen steadily over the last two decades such that the average person now is
working one more week per year than the average person in the mid 1970s This
steady increase has fueled research interest in the construct of Job Burnout (JB)
which is an emotional and physical exhaustion associated with ones work
Organizational Stress (OS) the perception of greater demands than available
resources in ones work environment is thought to be one of the chief
antecedents of JB However time spent under OS is thought to make its affects
on JB accumulate or worsen Work Role Withdrawal (WRW) the avoidance of
responsibilities or the deliberate reduction of inputs to ones job is believed to be
the chief consequence of JB
a Formally state these ideas as verbal hypotheses as equations and as a complex
directed graph (circle amp arrow diagram)
b Conceptually what is a mediator Define the term and identify the mediator in
your hypotheses in (a) What elements or steps in a study design (not statistics)
that would be helpful for detecting the mediating relationship that was proposed

subdomains of management Further demonstrate your understanding of
moderator variables by picking which variable in (a) is the moderator Show the
moderating relationship in an X-Y (or multi-layered) chart Again what elements
or steps in a study design (not statistics) would be helpful for detecting the
moderating effect implied above

recommendations You conduct a well-designed controlled study (details are unimportant) and discover students who use the new book perform 10 better on a standardized subject
matter exam than those using the old book (p = 027) Both books are readily availabe their prices are almost identical and both are equally acceptable to the instructors What is your recommendation to the chair
F1 Attached is the beginning of an article Your task is to write the results section by
1 making up and reporting plausible descriptive statistics that will help the
reader understand the results of the statistical tests you report and the nature of your
sample (Hint this can be presented in the form of a table)
2 describing and defending your choice of appropriate statistical tests of the
hypotheses and the steps that you would go through in carrying out these tests
3 making up and reporting results of these tests that are consistent with your
descriptive statistics and with any information in the rest of the article about the
results found (Hint this can be presented in the form of a table)
4 describing how well these results provide support for the hypotheses You
may want to note any relevant threats to validity here
Be sure to state any assumptions you make
F2 Assume that the Personnel Manager of a local firm Ms B dFlandres hired you to
analyze some data that her assistants had collected over the past several years The
data consist of (a) job performance ratings that were made in June of 1990 and (b)
scores on 25 predictor variables (eg measures of education job experience job
tenure job aptitude personality) that were measured when the individuals were hired
(between April 1987 and May 1988) She had data from only the 110 subjects (60
males and 50 females) who were hired during the period and were still employed by
the firm One objective of your analysis (analyses) is to determine how well the
performance criterion can be predicted by the predictors What strategy would you
use in analyzing the data Describeexplain (b) Is sample size an issue for your
analyses Explain If it is what will you do to deal with problems stemming from
sample size Assume that no additional data can be collected at this time (c) Some
preliminary analyses that you do reveal that five of the predictor variables correlate
(zero-order basis) about 75 with one another Will this influence the analyses that
you use Will it influence the validity of conclusions derived from your proposed
analyses (d) Ms dFlandres is interested in knowing if the predictor variables are
equally effective in predicting the job success of males and females What analysis
or analyses would you do to deal with this issue
F3 Assume that you have been provided with data on 12 conceptually distinct variables
that are moderately correlated with one another at the empirical level The data are
from students in four different college majors ie astronomy (A) biology (B)
criminology (C) and demography (D) The 12 measured variables fall into the
general categories of mental health (tension emotional withdrawal hallucinations
guilt feelings blunted affect and suspiciousness) and job satisfaction (work itself
supervision co-workers pay promotion prospects and working conditions) Your
task is to determine if the individuals in the four college majors differ from one
another on the 12 measured variables
(a) What statistical technique(s) would you use to test for group differences
Explain Be specific about the procedures(s) that you would use
(b) What statistical estimate would you use to estimate the extent to which the
groups differ from one another Be specific
F4 The following statistical table published in a recent issue of Work amp Occupations
was taken from an article discussing variables influencing resistance and citizenship
behaviors in the workplace Resistance behaviors include playing dumb withholding
effort work avoidance subverting particular managers and sabotage Citizenship
behaviors include cooperation engaging in peer training use of insider knowledge to
facilitate production commitment to organizational goals giving extra effort freely
Both measures are global constructs aggregated to the interval level and
standardized
The table reports the results of a series of ordinary least squares regression equations
with standardized coefficients Explain the meaning of the statistics presented What
do these statistics tell us generally about the relationship between resistance
behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows
Anomie Index -standardized interval level measure tapping multiple dimensions
The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)
F5 Researchers collected data from a sample of 350 companies on the following
variables
size (measured as number of employees)
Business Strategy (a nominal variable with 2 response options low-cost provider or
differentiator)
HR Strategy (a nominal variable with 2 response categories High commitment or
low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

assumptions usage and limitations
O3 How do exploratory and confirmatory factor analysis differ What are the
advantages and disadvantages of each
O4 Describe the differences between exploratory factor analysis (EFA) and
confirmatory factor analysis (CFA) When would you use one verses another
Are there ways to use EFA in a confirmatory way Can you use CFA in an
exploratory way Also describe the difference in principal components analysis
(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression

information in each matrix and its purpose
(2) For what purpose do researchers use factor analysis Explain In the process
provide a very brief description of a study for which factor analysis would be a
useful data analytic technique
O7 Factor analysis is an important statistical technique in organizational research
Describe factor analysis as an analytical tool including the following issues
a the reasons for using factor analysis
b the type of data necessary for using the technique appropriately
c the type of quantitative output that results from applying the technique
d how a researcher would use the output in his or her research
e how confirmatory factor analysis is different from exploratory
f the important issues and problems in using the technique
P) Structural Equation Models
P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)
Please comment on these restrictions versus access argument Which side do you
take
What are the strengths of SEM Give some examples
What are the weaknesses of SEM Give some examples

do that
B10 Assume that you have been hired by a national survey research company
Shash Inc to write items that will be used in a national survey of attitudes
toward capital punishment There are a number of criteria that can be used to
guide your item writing What are they Briefly describe five (5) such criteria
B11 Assume that you are going to conduct empirical research to determine the
impact of interpersonal trust on organizational decision making Describe and
justify the steps you might follow to develop an operationalization of the
interpersonal trust concept
B12 Assume that you are going to conduct empirical field research to assess the role

employee empowerment
Explain the procedures and standards you would use to determine if your
operationalization is valid and reliable
How would you assess the construct validity of such a measure
Discuss issues concerning the level of observation of your measure and level of
analysis of the data
B13 Assume you are interested in developing a new scale to measure construct X
Further assume that you have used previous literature and your own conceptual
development to delineate 2 dimensions of X specifically XF1 and XF2
Describe the steps you would go through in developing testing and evaluating
this new scale With regard to testing and evaluating be sure to consider the
role of factor analysis (both exploratory and confirmatory) and item analysis
Also you will want to make sure that your new multidimensional scale shows
evidence of validity (several kinds) and reliability so be sure to examine these
issues and explain how specific information gathered from the above testing
contributes to these concerns
C) Reliability
4) What is reliability and why is it so important What are the different ways reliability can be
assessed and when is each appropriate
15) What does coefficient alpha assess What are the ways coefficient alpha can be increased
C1 Describe and discuss the concept of reliability and all of its various forms
including their assessment When is each form appropriate and what information
is provided by each index
C2 In establishing congruence between multiple measurements we often compute
indices of reliability andor indices of agreement These two types of indices
address very different questions Your task is to 1) Define reliability and
agreement 2) Explain when each is useful using examples in which one but not
the other is appropriate and 3) Briefly describe two reliability indices and two
agreement indices

these methods map up with the definition of reliability What is the impact of the
number of test items and sample size on Chronbachs alpha and why would this
effect occur or not occur (Note Do NOT discuss inter-rater reliability)
C10 Schmidt and Hunter (1996) described several types of measures typically used in
organizational research and identified the type(s) of measurement error affecting
each of them in various situations For each measure below indicate the types of
error and sources of error that are most likely to affect it Then indicate what
could be done to reduce errors of measurement andor what can be done to
control for errors statistically
a Supervisor ratings of subordinates job performance
b Self-ratings of ones own job performance
c Self-reports of ones own job-related attitudes
d Sales figures for a salesperson (or production quantity for a production
worker)
d Aptitude tests taken as part of the hiring process
C11 Suppose you had conducted research on the relationship between organizational
commitment and rigidity of organizational structure in 200 firms Your measure
of rigidity was based on number of organizational authority levels and the degree
to which written organizational rules existed and defined role behaviors for
employees Thus an organization with a large number of organizational levels
and specific written policies defining appropriate role behaviors for employees
would score high on rigidity of organizational structure After analyzing your
data you find that there is a statistically significant negative correlation between
commitment and rigidity which is consistent with your hypothesis However the
reliabilities for your two measures are
(1) commitment = 23 (2) rigidity = 83
How should you interpret your results What could you do to fix this situation
Describe the specific steps (in order) you would follow to develop a more
reliable measure of commitment
C12 (a) Define the concept of reliability (of measures) in a clear concise and
accurate manner (b) Provide a formula that expresses the reliability of a measure
in terms of two components of variance ie total variance and the error
variance
D) Multi-level Assessment
D1 One of the major challenges for group-level research is the issue of aggregation of
individual data to the group level
(a) Under what conditions (eg types of data number of raters) should the various
interrater agreement and reliability methods be used (Rwg Kappa and Weighted
Kappa percent agreement average pairwise correlation ANOVA methods
(interclass correlation coefficient WABA)) What are the advantages and
disadvantages of each of the methods
(b) Explain the controversy between Frank Schmidt Larry James and others
regarding the differences between interrater agreement and interrater reliability
Who is right Do the differences matter in research practice
Defend your answers
(c) Review two articles from the organizational behavior literature that have had to
deal with aggregation issues Critique the methods the authors used to make
aggregation decisions
(d) Provide some advice to researchers regarding what they should do if interrater
agreement and reliability indices indicate that it is not legitimate to aggregate their
data
(e) Provide some ideas for avoiding the need to aggregate in group-level research
through creative research methods and measurement strategies
D2 Cross-levelmulti-level research is becoming more evident in the organizational
research literature This type of research raises many issues and presents many
challenges in terms of designing the research measuring variables and collecting
and analyzing the data Assume that you are interested in aggregating data (eg
from the individual to the group or from the firm to the industry) for one or more
variables What are the major issues you will need to deal with
D3 A researcher wants to measure organizational climate for continuous learning
Organizational climate is operationalized as a shared consensual aspect of the
organization -- the shared perception among employees that the organization values
and supports continuous learning Describe how you would measure organizational
climate in this case Specify (a) the level (ie individual group organization) at
which the construct exists (b) the level at which you would measure the construct
and (c) the procedures that you would use to establish that measurement is aligned
with theory (ie the construct validity of the measure)
E) General (Measurement)
E1 Studies in organizational behavior research often rely on single-item measures of
key constructs The use of single-item measures has long been criticized based
on the premise that single-item measures are unreliable However Wanous
(Wanous amp Hudy 2001 Wanous amp Reichers 1996 Wanous Reichers amp Hudy
1997) has recently argued that single-item measures can exhibit adequate
reliability Wanous based this conclusion on a procedure for estimating the
reliability of single-item measures using the classic formula for correction for
attenuation Subsequent studies have yielded mixed results regarding the
conclusions of Wanous (eg Loo amp Kells 1998 Nagy 2002) and the veracity
of the perspective advocated by Wanous remains in question Summarize and
assess the arguments for and against the use of single-item measures and
evaluate the procedure and evidence offered by Wanous regarding the reliability
of single-item measures Based on your assessment and evaluation develop
recommendations regarding the use of single-item measures in organizational
behavior research

E2 Ipsative measures have become prevalent in organizational behavior research
Ipsative measures ask respondents to answer questions relative to one another
such that the scores for all questions sum to the same constant for all respondents
Examples of ipsative measures include rankings Q-sorts and the allocation of a
fixed number of points (eg 100) across a set of response options Ipsative
measures may be contrasted with absolute measures which ask respondents to
answer questions independently from one another Absolute measures are
exemplified by rating scales using an interval or ratio numeric response format
The relative merits of ipsative and absolute measures have been debated for
decades (eg Cornwell amp Dunlap 1994 Hicks 1970 Johnson Wood amp
Blinkhorn 1988 Saville amp Wilson 1991 1992) yet the fundamental issues
underlying this debate have not been adequately addressed in organizational
behavior research For example measures of organizational culture and values
are often ipsative and some researchers advocate these measures over absolute
measures (eg Meglino amp Ravlin 1987 OReilly Chatman amp Caldwell 1991
Ravlin amp Meglino 1987 see also Rokeach amp Ball-Rokeach 1989) Review the
relative merits of absolute and ipsative measures Based on your review which
form of measurement is most appropriate and why Do your conclusions depend
on the construct being measured If so what types of constructs are best suited to
ipsative measures and what types are best suited to absolute measures Next
apply your conclusions to the measurement of culture and values in
organizations What specific arguments have been advanced in favor of ipsative
measures of culture and values How sound are these arguments Should ipsative
measures be used in the study of organizational culture and values If not how
can absolute measures of culture and values be developed that address the
concerns voiced by advocates of ipsative measures Provide a specific example
of the type of measure you would propose

E5 Suppose Roberta Von Eisenbrick is a researcher interested in the consequences of
AFFECTIVE CONFLICT (AC) in decision-making teams She gets access to a
variety of outcomes assessment committees at each of 87 different schools in
the Dallas Independent School District and gains permission to tape-record two
of their meetings (one in February and one in March) Such committees have
been formed to develop quantitative ways to track pursuit of school goals and
provide accountability to local and state governments These are often divisive
teams with heated meetings because what gets assessed is what usually gets
rewarded After both of these meetings the committee members each
fill out a short questionnaire that contains 20 Likert-type items measuring how
much AC occurred (eg People in our group often get angry with each other)
The individual scores are summed across items then averaged across team
members to come up with a group-level AC score for each of the 87 2
meetings The same procedures are followed for a 5-item measure of Group
Cohesiveness (GC) which is predicted to be reduced by higher levels of AC
Roberta also listens to every tape and from her expert judgment she rates each
groups meetings on the same 20 items Those 20 ratings are summed for each of
the 87 2 meetings Now Roberta is interested in evaluating her measure She
wants it to have excellent psychometric properties including reliability and
construct validity

criticized the fact that psychologists rely heavily on significance testing What
are the essential elements of these critiques What are some remedies to the
problems engendered by significance testing and why have these remedies not
been widely adopted
B3 (a) There is a debate among the IndustrialOrganizational psychologists on
whether we should abandon significance testing and report confidence intervals
instead Please summarize arguments from both sides and state your position on
this issue

D) ModeratorsMediators
D1 Moderation and mediation provide different ways to model third variable effects
(a) Please define both of these terms (b) Sketch a conceptual model to show how
each relates to main effects (c) Using variables of your choice please write
hypotheses to reflect both (d) Explain how each is tested analytically
D2 Discuss moderators and mediators Provide an example of how (1) a moderating
variable influences the relationship between the independent and dependent
variable and how (2) a mediating variable influences the relationship between
the independent and dependent variable Describe how you would test for both
moderation and mediation using regression
D3 Many theories in organizational research predict that the effects of one variable
on another are moderated by a third variable Such moderator effects are
typically tested by entering the product of two variables as a predictor after
controlling for the two variables that constitute the product Several researchers
have pointed out that this product is often highly correlated with the squares of
the two constituent variables and have suggested that moderating effects may be
tested after controlling not only for the two constituent variables but also their
squares (eg Cortina 1993 Ganzach 1998 Lubinski amp Humphreys 1990
MacCallum amp Mar 1995) Discuss the strengths and weaknesses of this
approach as compared to methods that use only the product term and its
constituent variables Conclude with recommendations as to when and under
what conditions organizational researchers should test moderator effects with the
squares of the constituent variables in the equation

D4 Assume you are interested in studying relationships amongst three variables X
Y and Z Your first hypothesis posits Z as a mediator of the relationship between
X and Y Your second hypothesis posits Z as a moderator of the relationship
between X and Y Draw the figures depicting each of these hypothesized
relationships and describe (make sure to write regression equations) how you
would test each of these hypotheses
D5 The amount of time and effort that the average person pours into his or her job
has risen steadily over the last two decades such that the average person now is
working one more week per year than the average person in the mid 1970s This
steady increase has fueled research interest in the construct of Job Burnout (JB)
which is an emotional and physical exhaustion associated with ones work
Organizational Stress (OS) the perception of greater demands than available
resources in ones work environment is thought to be one of the chief
antecedents of JB However time spent under OS is thought to make its affects
on JB accumulate or worsen Work Role Withdrawal (WRW) the avoidance of
responsibilities or the deliberate reduction of inputs to ones job is believed to be
the chief consequence of JB
a Formally state these ideas as verbal hypotheses as equations and as a complex
directed graph (circle amp arrow diagram)
b Conceptually what is a mediator Define the term and identify the mediator in
your hypotheses in (a) What elements or steps in a study design (not statistics)
that would be helpful for detecting the mediating relationship that was proposed
c What is a moderator What are some of the other names for it within various
subdomains of management Further demonstrate your understanding of
moderator variables by picking which variable in (a) is the moderator Show the
moderating relationship in an X-Y (or multi-layered) chart Again what elements
or steps in a study design (not statistics) would be helpful for detecting the
moderating effect implied above

student about the appropriate use of multiple comparisons and post hoc tests in
analysis of variance Your student colleague already has been introduced to ANOVA
and multiple regression Specifically you are to write out a description of how to test
for differences among the different levels or cells of a categorical variable In your
description you should discuss among other things

may want to note any relevant threats to validity here
Be sure to state any assumptions you make
F2 Assume that the Personnel Manager of a local firm Ms B dFlandres hired you to
analyze some data that her assistants had collected over the past several years The
data consist of (a) job performance ratings that were made in June of 1990 and (b)
scores on 25 predictor variables (eg measures of education job experience job
tenure job aptitude personality) that were measured when the individuals were hired
(between April 1987 and May 1988) She had data from only the 110 subjects (60
males and 50 females) who were hired during the period and were still employed by
the firm One objective of your analysis (analyses) is to determine how well the
performance criterion can be predicted by the predictors What strategy would you
use in analyzing the data Describeexplain (b) Is sample size an issue for your
analyses Explain If it is what will you do to deal with problems stemming from
sample size Assume that no additional data can be collected at this time (c) Some
preliminary analyses that you do reveal that five of the predictor variables correlate
(zero-order basis) about 75 with one another Will this influence the analyses that
you use Will it influence the validity of conclusions derived from your proposed
analyses (d) Ms dFlandres is interested in knowing if the predictor variables are
equally effective in predicting the job success of males and females What analysis
or analyses would you do to deal with this issue
F3 Assume that you have been provided with data on 12 conceptually distinct variables
that are moderately correlated with one another at the empirical level The data are
from students in four different college majors ie astronomy (A) biology (B)
criminology (C) and demography (D) The 12 measured variables fall into the
general categories of mental health (tension emotional withdrawal hallucinations
guilt feelings blunted affect and suspiciousness) and job satisfaction (work itself

effort work avoidance subverting particular managers and sabotage Citizenship
behaviors include cooperation engaging in peer training use of insider knowledge to
facilitate production commitment to organizational goals giving extra effort freely
Both measures are global constructs aggregated to the interval level and
standardized

with standardized coefficients Explain the meaning of the statistics presented What
do these statistics tell us generally about the relationship between resistance
behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows

The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)
F5 Researchers collected data from a sample of 350 companies on the following
variables
size (measured as number of employees)
Business Strategy (a nominal variable with 2 response options low-cost provider or
differentiator)
HR Strategy (a nominal variable with 2 response categories High commitment or
low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

I2 A study examined the effects of gender and pre-training motivation on the transfer of
training in terms of improved performance for 123 new industrial managers The
training was on supervisory skills and the dependent variable was based on the
appraisal of the supervisors performance before the training and three months after
the training The performance appraisal data were collected for research purposes
only and resulted in a total transfer score from 1 to 25 with 1 being low Pre-training
motivation was based on a 12 item Likert scale with an alpha of 86 Two groups

affected the statistical outcomes of the studies included in the literature review Meta-
analysis however allows one to statistically examine such effects Assume you are
conducting a meta-analysis of the relationship between leader behaviors and group
productivity Briefly describe the steps you would take in conducting a meta-
analysis What aspects of the original research designs would you examine in your
meta-analysis What steps would you take in gathering and coding data to enhance

assumptions usage and limitations
O3 How do exploratory and confirmatory factor analysis differ What are the
advantages and disadvantages of each
O4 Describe the differences between exploratory factor analysis (EFA) and
confirmatory factor analysis (CFA) When would you use one verses another
Are there ways to use EFA in a confirmatory way Can you use CFA in an
exploratory way Also describe the difference in principal components analysis
(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression
O6 The basic factor analysis model can be represented by the matrix algebraic
equation A B = C

information in each matrix and its purpose
(2) For what purpose do researchers use factor analysis Explain In the process
provide a very brief description of a study for which factor analysis would be a
useful data analytic technique
O7 Factor analysis is an important statistical technique in organizational research
Describe factor analysis as an analytical tool including the following issues
a the reasons for using factor analysis
b the type of data necessary for using the technique appropriately
c the type of quantitative output that results from applying the technique
d how a researcher would use the output in his or her research

f the important issues and problems in using the technique
P) Structural Equation Models
P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)
Please comment on these restrictions versus access argument Which side do you
take
What are the strengths of SEM Give some examples
What are the weaknesses of SEM Give some examples

C1 Describe and discuss the concept of reliability and all of its various forms
including their assessment When is each form appropriate and what information
is provided by each index
C2 In establishing congruence between multiple measurements we often compute
indices of reliability andor indices of agreement These two types of indices
address very different questions Your task is to 1) Define reliability and
agreement 2) Explain when each is useful using examples in which one but not
the other is appropriate and 3) Briefly describe two reliability indices and two
agreement indices
C3 Explain reliability in terms of the classical test theory What are the
consequences of unreliable measures in hypothesis testing What are the factors
that may affect the reliability of a multi-item scale
IC
C4 Generalizability theory is used within IO psychology more often today
However most researchers continue to use Classical Test Theory
conceptualizations of error to determine reliability What are the implications of
using classical test theory versus generalizability theory to assess reliability
C5 In establishing congruence between measurements we often compute indices of
reliability andor agreement Define reliability and agreement Explain the
differences in reliability and agreement and describe under what conditions
assessing reliability is more appropriate and under what conditions assessing
agreement is more appropriate
C6 Define measurement reliability in terms of a specific measurement theory (eg
true test score theory domain sampling theory generalizability theory IRT)
Discuss the different approaches for estimating reliability and the contexts in
which each might be appropriate Use examples throughout
C7 What are the consequences of unreliability in a measure
C8 What are some of the conditions that might keep the internal consistency (eg
alpha) of a given measure low Is a low alpha always a sign of a problematic
measure
C9 Define reliability Name some methods of calculating reliability How well do
these methods map up with the definition of reliability What is the impact of the
number of test items and sample size on Chronbachs alpha and why would this
effect occur or not occur (Note Do NOT discuss inter-rater reliability)
C10 Schmidt and Hunter (1996) described several types of measures typically used in
organizational research and identified the type(s) of measurement error affecting
each of them in various situations For each measure below indicate the types of
error and sources of error that are most likely to affect it Then indicate what
could be done to reduce errors of measurement andor what can be done to
control for errors statistically
a Supervisor ratings of subordinates job performance
b Self-ratings of ones own job performance
c Self-reports of ones own job-related attitudes
d Sales figures for a salesperson (or production quantity for a production
worker)
d Aptitude tests taken as part of the hiring process
C11 Suppose you had conducted research on the relationship between organizational
commitment and rigidity of organizational structure in 200 firms Your measure
of rigidity was based on number of organizational authority levels and the degree
to which written organizational rules existed and defined role behaviors for
employees Thus an organization with a large number of organizational levels
and specific written policies defining appropriate role behaviors for employees
would score high on rigidity of organizational structure After analyzing your
data you find that there is a statistically significant negative correlation between
commitment and rigidity which is consistent with your hypothesis However the
reliabilities for your two measures are
(1) commitment = 23 (2) rigidity = 83
How should you interpret your results What could you do to fix this situation
Describe the specific steps (in order) you would follow to develop a more
reliable measure of commitment
C12 (a) Define the concept of reliability (of measures) in a clear concise and
accurate manner (b) Provide a formula that expresses the reliability of a measure
in terms of two components of variance ie total variance and the error
variance
D) Multi-level Assessment
D1 One of the major challenges for group-level research is the issue of aggregation of
individual data to the group level
(a) Under what conditions (eg types of data number of raters) should the various
interrater agreement and reliability methods be used (Rwg Kappa and Weighted
Kappa percent agreement average pairwise correlation ANOVA methods
(interclass correlation coefficient WABA)) What are the advantages and
disadvantages of each of the methods
(b) Explain the controversy between Frank Schmidt Larry James and others
regarding the differences between interrater agreement and interrater reliability

deal with aggregation issues Critique the methods the authors used to make
aggregation decisions
(d) Provide some advice to researchers regarding what they should do if interrater
agreement and reliability indices indicate that it is not legitimate to aggregate their
data
(e) Provide some ideas for avoiding the need to aggregate in group-level research
through creative research methods and measurement strategies
D2 Cross-levelmulti-level research is becoming more evident in the organizational
research literature This type of research raises many issues and presents many
challenges in terms of designing the research measuring variables and collecting
and analyzing the data Assume that you are interested in aggregating data (eg
from the individual to the group or from the firm to the industry) for one or more
variables What are the major issues you will need to deal with
D3 A researcher wants to measure organizational climate for continuous learning
Organizational climate is operationalized as a shared consensual aspect of the
organization -- the shared perception among employees that the organization values
and supports continuous learning Describe how you would measure organizational
climate in this case Specify (a) the level (ie individual group organization) at
which the construct exists (b) the level at which you would measure the construct
and (c) the procedures that you would use to establish that measurement is aligned
with theory (ie the construct validity of the measure)
E) General (Measurement)
E1 Studies in organizational behavior research often rely on single-item measures of
key constructs The use of single-item measures has long been criticized based
on the premise that single-item measures are unreliable However Wanous
(Wanous amp Hudy 2001 Wanous amp Reichers 1996 Wanous Reichers amp Hudy
1997) has recently argued that single-item measures can exhibit adequate
reliability Wanous based this conclusion on a procedure for estimating the
reliability of single-item measures using the classic formula for correction for
attenuation Subsequent studies have yielded mixed results regarding the
conclusions of Wanous (eg Loo amp Kells 1998 Nagy 2002) and the veracity
of the perspective advocated by Wanous remains in question Summarize and
assess the arguments for and against the use of single-item measures and
evaluate the procedure and evidence offered by Wanous regarding the reliability
of single-item measures Based on your assessment and evaluation develop
recommendations regarding the use of single-item measures in organizational
behavior research

E2 Ipsative measures have become prevalent in organizational behavior research
Ipsative measures ask respondents to answer questions relative to one another
such that the scores for all questions sum to the same constant for all respondents
Examples of ipsative measures include rankings Q-sorts and the allocation of a
fixed number of points (eg 100) across a set of response options Ipsative
measures may be contrasted with absolute measures which ask respondents to
answer questions independently from one another Absolute measures are
exemplified by rating scales using an interval or ratio numeric response format
The relative merits of ipsative and absolute measures have been debated for
decades (eg Cornwell amp Dunlap 1994 Hicks 1970 Johnson Wood amp
Blinkhorn 1988 Saville amp Wilson 1991 1992) yet the fundamental issues
underlying this debate have not been adequately addressed in organizational
behavior research For example measures of organizational culture and values
are often ipsative and some researchers advocate these measures over absolute
measures (eg Meglino amp Ravlin 1987 OReilly Chatman amp Caldwell 1991
Ravlin amp Meglino 1987 see also Rokeach amp Ball-Rokeach 1989) Review the
relative merits of absolute and ipsative measures Based on your review which
form of measurement is most appropriate and why Do your conclusions depend
on the construct being measured If so what types of constructs are best suited to
ipsative measures and what types are best suited to absolute measures Next
apply your conclusions to the measurement of culture and values in
organizations What specific arguments have been advanced in favor of ipsative
measures of culture and values How sound are these arguments Should ipsative
measures be used in the study of organizational culture and values If not how
can absolute measures of culture and values be developed that address the
concerns voiced by advocates of ipsative measures Provide a specific example
of the type of measure you would propose

of their meetings (one in February and one in March) Such committees have
been formed to develop quantitative ways to track pursuit of school goals and
provide accountability to local and state governments These are often divisive
teams with heated meetings because what gets assessed is what usually gets
rewarded After both of these meetings the committee members each
fill out a short questionnaire that contains 20 Likert-type items measuring how
much AC occurred (eg People in our group often get angry with each other)
The individual scores are summed across items then averaged across team
members to come up with a group-level AC score for each of the 87 2
meetings The same procedures are followed for a 5-item measure of Group
Cohesiveness (GC) which is predicted to be reduced by higher levels of AC
Roberta also listens to every tape and from her expert judgment she rates each
groups meetings on the same 20 items Those 20 ratings are summed for each of
the 87 2 meetings Now Roberta is interested in evaluating her measure She
wants it to have excellent psychometric properties including reliability and
construct validity

definition to the context given above
b How could you estimate the reliability of this new measure of AC Cover at
least three kinds of estimates and the sources of error each one assumes or is
estimating Pick one of those kinds of estimates and provide a rationale for using
it
c What is construct validity Discuss how the (un)reliability of the AC measure
could affect the conclusions one would draw from a study involving it and GC In
your discussion be sure to go over the connection between reliability and
validity and the connection between reliability and the probability of Type I or
Type II statistical errors

are the essential elements of these critiques What are some remedies to the
problems engendered by significance testing and why have these remedies not
been widely adopted

D) ModeratorsMediators
D1 Moderation and mediation provide different ways to model third variable effects
(a) Please define both of these terms (b) Sketch a conceptual model to show how
each relates to main effects (c) Using variables of your choice please write
hypotheses to reflect both (d) Explain how each is tested analytically
D2 Discuss moderators and mediators Provide an example of how (1) a moderating
variable influences the relationship between the independent and dependent
variable and how (2) a mediating variable influences the relationship between
the independent and dependent variable Describe how you would test for both
moderation and mediation using regression
D3 Many theories in organizational research predict that the effects of one variable
on another are moderated by a third variable Such moderator effects are
typically tested by entering the product of two variables as a predictor after
controlling for the two variables that constitute the product Several researchers
have pointed out that this product is often highly correlated with the squares of
the two constituent variables and have suggested that moderating effects may be
tested after controlling not only for the two constituent variables but also their
squares (eg Cortina 1993 Ganzach 1998 Lubinski amp Humphreys 1990
MacCallum amp Mar 1995) Discuss the strengths and weaknesses of this
approach as compared to methods that use only the product term and its
constituent variables Conclude with recommendations as to when and under
what conditions organizational researchers should test moderator effects with the
squares of the constituent variables in the equation

D4 Assume you are interested in studying relationships amongst three variables X
Y and Z Your first hypothesis posits Z as a mediator of the relationship between
X and Y Your second hypothesis posits Z as a moderator of the relationship
between X and Y Draw the figures depicting each of these hypothesized
relationships and describe (make sure to write regression equations) how you
would test each of these hypotheses
D5 The amount of time and effort that the average person pours into his or her job
has risen steadily over the last two decades such that the average person now is
working one more week per year than the average person in the mid 1970s This
steady increase has fueled research interest in the construct of Job Burnout (JB)
which is an emotional and physical exhaustion associated with ones work
Organizational Stress (OS) the perception of greater demands than available
resources in ones work environment is thought to be one of the chief
antecedents of JB However time spent under OS is thought to make its affects
on JB accumulate or worsen Work Role Withdrawal (WRW) the avoidance of
responsibilities or the deliberate reduction of inputs to ones job is believed to be
the chief consequence of JB
a Formally state these ideas as verbal hypotheses as equations and as a complex
directed graph (circle amp arrow diagram)
b Conceptually what is a mediator Define the term and identify the mediator in
your hypotheses in (a) What elements or steps in a study design (not statistics)
that would be helpful for detecting the mediating relationship that was proposed

subdomains of management Further demonstrate your understanding of
moderator variables by picking which variable in (a) is the moderator Show the
moderating relationship in an X-Y (or multi-layered) chart Again what elements
or steps in a study design (not statistics) would be helpful for detecting the
moderating effect implied above

recommendations You conduct a well-designed controlled study (details are unimportant) and discover students who use the new book perform 10 better on a standardized subject
matter exam than those using the old book (p = 027) Both books are readily availabe their prices are almost identical and both are equally acceptable to the instructors What is your recommendation to the chair
F1 Attached is the beginning of an article Your task is to write the results section by
1 making up and reporting plausible descriptive statistics that will help the
reader understand the results of the statistical tests you report and the nature of your
sample (Hint this can be presented in the form of a table)
2 describing and defending your choice of appropriate statistical tests of the
hypotheses and the steps that you would go through in carrying out these tests
3 making up and reporting results of these tests that are consistent with your
descriptive statistics and with any information in the rest of the article about the
results found (Hint this can be presented in the form of a table)
4 describing how well these results provide support for the hypotheses You
may want to note any relevant threats to validity here
Be sure to state any assumptions you make
F2 Assume that the Personnel Manager of a local firm Ms B dFlandres hired you to
analyze some data that her assistants had collected over the past several years The
data consist of (a) job performance ratings that were made in June of 1990 and (b)
scores on 25 predictor variables (eg measures of education job experience job
tenure job aptitude personality) that were measured when the individuals were hired
(between April 1987 and May 1988) She had data from only the 110 subjects (60
males and 50 females) who were hired during the period and were still employed by
the firm One objective of your analysis (analyses) is to determine how well the
performance criterion can be predicted by the predictors What strategy would you
use in analyzing the data Describeexplain (b) Is sample size an issue for your
analyses Explain If it is what will you do to deal with problems stemming from
sample size Assume that no additional data can be collected at this time (c) Some
preliminary analyses that you do reveal that five of the predictor variables correlate
(zero-order basis) about 75 with one another Will this influence the analyses that
you use Will it influence the validity of conclusions derived from your proposed
analyses (d) Ms dFlandres is interested in knowing if the predictor variables are
equally effective in predicting the job success of males and females What analysis
or analyses would you do to deal with this issue
F3 Assume that you have been provided with data on 12 conceptually distinct variables
that are moderately correlated with one another at the empirical level The data are
from students in four different college majors ie astronomy (A) biology (B)
criminology (C) and demography (D) The 12 measured variables fall into the
general categories of mental health (tension emotional withdrawal hallucinations
guilt feelings blunted affect and suspiciousness) and job satisfaction (work itself
supervision co-workers pay promotion prospects and working conditions) Your
task is to determine if the individuals in the four college majors differ from one
another on the 12 measured variables
(a) What statistical technique(s) would you use to test for group differences
Explain Be specific about the procedures(s) that you would use
(b) What statistical estimate would you use to estimate the extent to which the
groups differ from one another Be specific
F4 The following statistical table published in a recent issue of Work amp Occupations
was taken from an article discussing variables influencing resistance and citizenship
behaviors in the workplace Resistance behaviors include playing dumb withholding
effort work avoidance subverting particular managers and sabotage Citizenship
behaviors include cooperation engaging in peer training use of insider knowledge to
facilitate production commitment to organizational goals giving extra effort freely
Both measures are global constructs aggregated to the interval level and
standardized
The table reports the results of a series of ordinary least squares regression equations
with standardized coefficients Explain the meaning of the statistics presented What
do these statistics tell us generally about the relationship between resistance
behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows
Anomie Index -standardized interval level measure tapping multiple dimensions
The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)
F5 Researchers collected data from a sample of 350 companies on the following
variables
size (measured as number of employees)
Business Strategy (a nominal variable with 2 response options low-cost provider or
differentiator)
HR Strategy (a nominal variable with 2 response categories High commitment or
low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

exploratory way Also describe the difference in principal components analysis
(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression

analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)
Please comment on these restrictions versus access argument Which side do you
take

C11 Suppose you had conducted research on the relationship between organizational
commitment and rigidity of organizational structure in 200 firms Your measure
of rigidity was based on number of organizational authority levels and the degree
to which written organizational rules existed and defined role behaviors for
employees Thus an organization with a large number of organizational levels
and specific written policies defining appropriate role behaviors for employees
would score high on rigidity of organizational structure After analyzing your
data you find that there is a statistically significant negative correlation between
commitment and rigidity which is consistent with your hypothesis However the
reliabilities for your two measures are
(1) commitment = 23 (2) rigidity = 83
How should you interpret your results What could you do to fix this situation
Describe the specific steps (in order) you would follow to develop a more
reliable measure of commitment
C12 (a) Define the concept of reliability (of measures) in a clear concise and
accurate manner (b) Provide a formula that expresses the reliability of a measure
in terms of two components of variance ie total variance and the error
variance
D) Multi-level Assessment
D1 One of the major challenges for group-level research is the issue of aggregation of
individual data to the group level
(a) Under what conditions (eg types of data number of raters) should the various
interrater agreement and reliability methods be used (Rwg Kappa and Weighted
Kappa percent agreement average pairwise correlation ANOVA methods
(interclass correlation coefficient WABA)) What are the advantages and
disadvantages of each of the methods
(b) Explain the controversy between Frank Schmidt Larry James and others
regarding the differences between interrater agreement and interrater reliability
Who is right Do the differences matter in research practice
Defend your answers
(c) Review two articles from the organizational behavior literature that have had to
deal with aggregation issues Critique the methods the authors used to make
aggregation decisions
(d) Provide some advice to researchers regarding what they should do if interrater
agreement and reliability indices indicate that it is not legitimate to aggregate their
data
(e) Provide some ideas for avoiding the need to aggregate in group-level research
through creative research methods and measurement strategies
D2 Cross-levelmulti-level research is becoming more evident in the organizational
research literature This type of research raises many issues and presents many
challenges in terms of designing the research measuring variables and collecting
and analyzing the data Assume that you are interested in aggregating data (eg
from the individual to the group or from the firm to the industry) for one or more
variables What are the major issues you will need to deal with
D3 A researcher wants to measure organizational climate for continuous learning
Organizational climate is operationalized as a shared consensual aspect of the
organization -- the shared perception among employees that the organization values
and supports continuous learning Describe how you would measure organizational
climate in this case Specify (a) the level (ie individual group organization) at
which the construct exists (b) the level at which you would measure the construct
and (c) the procedures that you would use to establish that measurement is aligned
with theory (ie the construct validity of the measure)
E) General (Measurement)
E1 Studies in organizational behavior research often rely on single-item measures of
key constructs The use of single-item measures has long been criticized based
on the premise that single-item measures are unreliable However Wanous
(Wanous amp Hudy 2001 Wanous amp Reichers 1996 Wanous Reichers amp Hudy
1997) has recently argued that single-item measures can exhibit adequate
reliability Wanous based this conclusion on a procedure for estimating the
reliability of single-item measures using the classic formula for correction for
attenuation Subsequent studies have yielded mixed results regarding the
conclusions of Wanous (eg Loo amp Kells 1998 Nagy 2002) and the veracity
of the perspective advocated by Wanous remains in question Summarize and
assess the arguments for and against the use of single-item measures and
evaluate the procedure and evidence offered by Wanous regarding the reliability
of single-item measures Based on your assessment and evaluation develop
recommendations regarding the use of single-item measures in organizational
behavior research

E2 Ipsative measures have become prevalent in organizational behavior research
Ipsative measures ask respondents to answer questions relative to one another
such that the scores for all questions sum to the same constant for all respondents
Examples of ipsative measures include rankings Q-sorts and the allocation of a
fixed number of points (eg 100) across a set of response options Ipsative
measures may be contrasted with absolute measures which ask respondents to
answer questions independently from one another Absolute measures are
exemplified by rating scales using an interval or ratio numeric response format
The relative merits of ipsative and absolute measures have been debated for
decades (eg Cornwell amp Dunlap 1994 Hicks 1970 Johnson Wood amp
Blinkhorn 1988 Saville amp Wilson 1991 1992) yet the fundamental issues
underlying this debate have not been adequately addressed in organizational
behavior research For example measures of organizational culture and values
are often ipsative and some researchers advocate these measures over absolute
measures (eg Meglino amp Ravlin 1987 OReilly Chatman amp Caldwell 1991
Ravlin amp Meglino 1987 see also Rokeach amp Ball-Rokeach 1989) Review the
relative merits of absolute and ipsative measures Based on your review which
form of measurement is most appropriate and why Do your conclusions depend
on the construct being measured If so what types of constructs are best suited to
ipsative measures and what types are best suited to absolute measures Next
apply your conclusions to the measurement of culture and values in
organizations What specific arguments have been advanced in favor of ipsative
measures of culture and values How sound are these arguments Should ipsative
measures be used in the study of organizational culture and values If not how
can absolute measures of culture and values be developed that address the
concerns voiced by advocates of ipsative measures Provide a specific example
of the type of measure you would propose

facets of a concept Although such measures are prevalent and in some cases are

E5 Suppose Roberta Von Eisenbrick is a researcher interested in the consequences of
AFFECTIVE CONFLICT (AC) in decision-making teams She gets access to a
variety of outcomes assessment committees at each of 87 different schools in
the Dallas Independent School District and gains permission to tape-record two
of their meetings (one in February and one in March) Such committees have
been formed to develop quantitative ways to track pursuit of school goals and
provide accountability to local and state governments These are often divisive
teams with heated meetings because what gets assessed is what usually gets
rewarded After both of these meetings the committee members each
fill out a short questionnaire that contains 20 Likert-type items measuring how
much AC occurred (eg People in our group often get angry with each other)
The individual scores are summed across items then averaged across team
members to come up with a group-level AC score for each of the 87 2
meetings The same procedures are followed for a 5-item measure of Group
Cohesiveness (GC) which is predicted to be reduced by higher levels of AC
Roberta also listens to every tape and from her expert judgment she rates each
groups meetings on the same 20 items Those 20 ratings are summed for each of
the 87 2 meetings Now Roberta is interested in evaluating her measure She
wants it to have excellent psychometric properties including reliability and
construct validity

are the essential elements of these critiques What are some remedies to the
problems engendered by significance testing and why have these remedies not
been widely adopted
B3 (a) There is a debate among the IndustrialOrganizational psychologists on
whether we should abandon significance testing and report confidence intervals
instead Please summarize arguments from both sides and state your position on
this issue

things that researchers have inappropriately sanctified the p lt 05 level of
significance Describe and critique the arguments for and against the use of
statistical significance testing in empirical research What information other than
significance levels can be used to interpret the meaning of empirical research

D) ModeratorsMediators
D1 Moderation and mediation provide different ways to model third variable effects
(a) Please define both of these terms (b) Sketch a conceptual model to show how
each relates to main effects (c) Using variables of your choice please write
hypotheses to reflect both (d) Explain how each is tested analytically
D2 Discuss moderators and mediators Provide an example of how (1) a moderating
variable influences the relationship between the independent and dependent
variable and how (2) a mediating variable influences the relationship between
the independent and dependent variable Describe how you would test for both
moderation and mediation using regression
D3 Many theories in organizational research predict that the effects of one variable
on another are moderated by a third variable Such moderator effects are
typically tested by entering the product of two variables as a predictor after
controlling for the two variables that constitute the product Several researchers
have pointed out that this product is often highly correlated with the squares of
the two constituent variables and have suggested that moderating effects may be
tested after controlling not only for the two constituent variables but also their
squares (eg Cortina 1993 Ganzach 1998 Lubinski amp Humphreys 1990
MacCallum amp Mar 1995) Discuss the strengths and weaknesses of this
approach as compared to methods that use only the product term and its
constituent variables Conclude with recommendations as to when and under
what conditions organizational researchers should test moderator effects with the
squares of the constituent variables in the equation

D4 Assume you are interested in studying relationships amongst three variables X
Y and Z Your first hypothesis posits Z as a mediator of the relationship between
X and Y Your second hypothesis posits Z as a moderator of the relationship
between X and Y Draw the figures depicting each of these hypothesized
relationships and describe (make sure to write regression equations) how you
would test each of these hypotheses
D5 The amount of time and effort that the average person pours into his or her job
has risen steadily over the last two decades such that the average person now is
working one more week per year than the average person in the mid 1970s This
steady increase has fueled research interest in the construct of Job Burnout (JB)
which is an emotional and physical exhaustion associated with ones work
Organizational Stress (OS) the perception of greater demands than available
resources in ones work environment is thought to be one of the chief
antecedents of JB However time spent under OS is thought to make its affects
on JB accumulate or worsen Work Role Withdrawal (WRW) the avoidance of
responsibilities or the deliberate reduction of inputs to ones job is believed to be
the chief consequence of JB
a Formally state these ideas as verbal hypotheses as equations and as a complex
directed graph (circle amp arrow diagram)
b Conceptually what is a mediator Define the term and identify the mediator in
your hypotheses in (a) What elements or steps in a study design (not statistics)
that would be helpful for detecting the mediating relationship that was proposed
c What is a moderator What are some of the other names for it within various
subdomains of management Further demonstrate your understanding of
moderator variables by picking which variable in (a) is the moderator Show the
moderating relationship in an X-Y (or multi-layered) chart Again what elements
or steps in a study design (not statistics) would be helpful for detecting the
moderating effect implied above
E) Multiple Comparisons
E1 In your role as professional colleague you are called upon to advise another doctoral
student about the appropriate use of multiple comparisons and post hoc tests in
analysis of variance Your student colleague already has been introduced to ANOVA
and multiple regression Specifically you are to write out a description of how to test
for differences among the different levels or cells of a categorical variable In your
description you should discuss among other things
a the statistical and philosophical issues raised by post hoc analysis and data
snooping
b the different multiple comparison methods commonly used by researchers to test
for differences among cell means and
c the advantages and disadvantages of each method
Note Your written description will be evaluated based on your demonstrated
competence with the statistical method not on the pedagogy of your explanation
F) Applied Data Analysis
16) Q Your departmental chair is considering a new textbook and has asked for your
recommendations You conduct a well-designed controlled study (details are unimportant) and discover students who use the new book perform 10 better on a standardized subject
matter exam than those using the old book (p = 027) Both books are readily availabe their prices are almost identical and both are equally acceptable to the instructors What is your recommendation to the chair
F1 Attached is the beginning of an article Your task is to write the results section by
1 making up and reporting plausible descriptive statistics that will help the
reader understand the results of the statistical tests you report and the nature of your
sample (Hint this can be presented in the form of a table)
2 describing and defending your choice of appropriate statistical tests of the
hypotheses and the steps that you would go through in carrying out these tests
3 making up and reporting results of these tests that are consistent with your
descriptive statistics and with any information in the rest of the article about the
results found (Hint this can be presented in the form of a table)
4 describing how well these results provide support for the hypotheses You
may want to note any relevant threats to validity here
Be sure to state any assumptions you make
F2 Assume that the Personnel Manager of a local firm Ms B dFlandres hired you to
analyze some data that her assistants had collected over the past several years The
data consist of (a) job performance ratings that were made in June of 1990 and (b)
scores on 25 predictor variables (eg measures of education job experience job
tenure job aptitude personality) that were measured when the individuals were hired
(between April 1987 and May 1988) She had data from only the 110 subjects (60
males and 50 females) who were hired during the period and were still employed by
the firm One objective of your analysis (analyses) is to determine how well the
performance criterion can be predicted by the predictors What strategy would you
use in analyzing the data Describeexplain (b) Is sample size an issue for your
analyses Explain If it is what will you do to deal with problems stemming from
sample size Assume that no additional data can be collected at this time (c) Some
preliminary analyses that you do reveal that five of the predictor variables correlate
(zero-order basis) about 75 with one another Will this influence the analyses that
you use Will it influence the validity of conclusions derived from your proposed
analyses (d) Ms dFlandres is interested in knowing if the predictor variables are
equally effective in predicting the job success of males and females What analysis
or analyses would you do to deal with this issue
F3 Assume that you have been provided with data on 12 conceptually distinct variables
that are moderately correlated with one another at the empirical level The data are
from students in four different college majors ie astronomy (A) biology (B)
criminology (C) and demography (D) The 12 measured variables fall into the
general categories of mental health (tension emotional withdrawal hallucinations
guilt feelings blunted affect and suspiciousness) and job satisfaction (work itself
supervision co-workers pay promotion prospects and working conditions) Your
task is to determine if the individuals in the four college majors differ from one
another on the 12 measured variables
(a) What statistical technique(s) would you use to test for group differences
Explain Be specific about the procedures(s) that you would use
(b) What statistical estimate would you use to estimate the extent to which the
groups differ from one another Be specific
F4 The following statistical table published in a recent issue of Work amp Occupations
was taken from an article discussing variables influencing resistance and citizenship
behaviors in the workplace Resistance behaviors include playing dumb withholding
effort work avoidance subverting particular managers and sabotage Citizenship
behaviors include cooperation engaging in peer training use of insider knowledge to
facilitate production commitment to organizational goals giving extra effort freely
Both measures are global constructs aggregated to the interval level and
standardized
The table reports the results of a series of ordinary least squares regression equations
with standardized coefficients Explain the meaning of the statistics presented What
do these statistics tell us generally about the relationship between resistance
behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows
Anomie Index -standardized interval level measure tapping multiple dimensions
The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)
F5 Researchers collected data from a sample of 350 companies on the following
variables
size (measured as number of employees)
Business Strategy (a nominal variable with 2 response options low-cost provider or
differentiator)
HR Strategy (a nominal variable with 2 response categories High commitment or
low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

I2 A study examined the effects of gender and pre-training motivation on the transfer of
training in terms of improved performance for 123 new industrial managers The
training was on supervisory skills and the dependent variable was based on the

J) Meta-analysis
J1 There exist two categories of literature review narrative and quantitative Each
category as typically implemented has certain advantages and disadvantages
Describe the advantages and disadvantages associated with each approach taking
particular care to enumerate the disadvantages associated with quantitative review
Then offer two ways that meta-analysis might be combined with other analytical
techniques to move beyond the focus of bivariate relationships that is typical of meta-
analysis
J2 Schmidt has argued that primary research does not allow one to discover general
scientific laws but that meta-analytic research does What are the arguments in favor
of or against this position In what areas of research (if any) has Schmidts
prediction come closest to coming true
J3 The so-called (by Hunter Schmidt and Jackson 1983) state of the art meta-
analysis method attempts to account for various sources of error that might produce
apparent variation in effect sizes across studies (a) Discuss the three most important
sources of error that meta-analysis addresses (b) Discuss the potential contribution
that a meta-analysis can make to theory building in the organizational sciences (c)
Describe the circumstances that you would consider when deciding whether to
perform a meta-analysis
J4 Meta-analysis has been hailed as a miracle cure and criticized as smoke and
mirrors Explain both sides of the debate and then lay out the role of meta-analysis
as you see it within the time span of your career as an academic To do this use
examples of already written (or yet to be written) articles as models
J5 A frequent criticism of non-quantitative research summaries (literature reviews) is
that researchers do not carefully examine how particular research designs might have
affected the statistical outcomes of the studies included in the literature review Meta-
analysis however allows one to statistically examine such effects Assume you are
conducting a meta-analysis of the relationship between leader behaviors and group
productivity Briefly describe the steps you would take in conducting a meta-
analysis What aspects of the original research designs would you examine in your
meta-analysis What steps would you take in gathering and coding data to enhance
the credibility of your analysis
K) MTMM
K1 One method often used by social scientists to demonstrate the construct validity of
measures is the multi-trait multi-method matrix developed by Campbell and
Fiske (1959) Briefly describe how this matrix is obtained or constructed by a
researcher and then describe how each of the elements of the matrix is used to
demonstrate the reliability andor construct validity of the measure(s)
IC
K2 Describe the logic of the multi-trait multi-method (MTMM) analysis in terms of
the criteria for evaluating the validity of a set of measurement procedures
Interpret the following MTMM in terms of what it might infer about the validity
of the different measurement procedures You may impose any assumptions on
the data you prefer For example you might want to discuss the matrix under the
assumption that traits A B amp C are mutually independent Please justify and
make explicit any assumptions you make

assumptions usage and limitations
O3 How do exploratory and confirmatory factor analysis differ What are the
advantages and disadvantages of each
O4 Describe the differences between exploratory factor analysis (EFA) and
confirmatory factor analysis (CFA) When would you use one verses another
Are there ways to use EFA in a confirmatory way Can you use CFA in an
exploratory way Also describe the difference in principal components analysis
(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression

P) Structural Equation Models
P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)
Please comment on these restrictions versus access argument Which side do you
take
What are the strengths of SEM Give some examples
What are the weaknesses of SEM Give some examples

D2 Cross-levelmulti-level research is becoming more evident in the organizational
research literature This type of research raises many issues and presents many
challenges in terms of designing the research measuring variables and collecting

D3 A researcher wants to measure organizational climate for continuous learning
Organizational climate is operationalized as a shared consensual aspect of the
organization -- the shared perception among employees that the organization values
and supports continuous learning Describe how you would measure organizational
climate in this case Specify (a) the level (ie individual group organization) at
which the construct exists (b) the level at which you would measure the construct
and (c) the procedures that you would use to establish that measurement is aligned
with theory (ie the construct validity of the measure)
E) General (Measurement)
E1 Studies in organizational behavior research often rely on single-item measures of
key constructs The use of single-item measures has long been criticized based
on the premise that single-item measures are unreliable However Wanous
(Wanous amp Hudy 2001 Wanous amp Reichers 1996 Wanous Reichers amp Hudy
1997) has recently argued that single-item measures can exhibit adequate
reliability Wanous based this conclusion on a procedure for estimating the
reliability of single-item measures using the classic formula for correction for
attenuation Subsequent studies have yielded mixed results regarding the
conclusions of Wanous (eg Loo amp Kells 1998 Nagy 2002) and the veracity
of the perspective advocated by Wanous remains in question Summarize and
assess the arguments for and against the use of single-item measures and
evaluate the procedure and evidence offered by Wanous regarding the reliability
of single-item measures Based on your assessment and evaluation develop
recommendations regarding the use of single-item measures in organizational
behavior research

E2 Ipsative measures have become prevalent in organizational behavior research
Ipsative measures ask respondents to answer questions relative to one another
such that the scores for all questions sum to the same constant for all respondents
Examples of ipsative measures include rankings Q-sorts and the allocation of a
fixed number of points (eg 100) across a set of response options Ipsative
measures may be contrasted with absolute measures which ask respondents to
answer questions independently from one another Absolute measures are
exemplified by rating scales using an interval or ratio numeric response format
The relative merits of ipsative and absolute measures have been debated for
decades (eg Cornwell amp Dunlap 1994 Hicks 1970 Johnson Wood amp
Blinkhorn 1988 Saville amp Wilson 1991 1992) yet the fundamental issues
underlying this debate have not been adequately addressed in organizational
behavior research For example measures of organizational culture and values
are often ipsative and some researchers advocate these measures over absolute
measures (eg Meglino amp Ravlin 1987 OReilly Chatman amp Caldwell 1991
Ravlin amp Meglino 1987 see also Rokeach amp Ball-Rokeach 1989) Review the
relative merits of absolute and ipsative measures Based on your review which
form of measurement is most appropriate and why Do your conclusions depend
on the construct being measured If so what types of constructs are best suited to
ipsative measures and what types are best suited to absolute measures Next
apply your conclusions to the measurement of culture and values in
organizations What specific arguments have been advanced in favor of ipsative
measures of culture and values How sound are these arguments Should ipsative
measures be used in the study of organizational culture and values If not how
can absolute measures of culture and values be developed that address the
concerns voiced by advocates of ipsative measures Provide a specific example
of the type of measure you would propose

E5 Suppose Roberta Von Eisenbrick is a researcher interested in the consequences of
AFFECTIVE CONFLICT (AC) in decision-making teams She gets access to a
variety of outcomes assessment committees at each of 87 different schools in
the Dallas Independent School District and gains permission to tape-record two
of their meetings (one in February and one in March) Such committees have
been formed to develop quantitative ways to track pursuit of school goals and
provide accountability to local and state governments These are often divisive
teams with heated meetings because what gets assessed is what usually gets
rewarded After both of these meetings the committee members each
fill out a short questionnaire that contains 20 Likert-type items measuring how
much AC occurred (eg People in our group often get angry with each other)
The individual scores are summed across items then averaged across team
members to come up with a group-level AC score for each of the 87 2
meetings The same procedures are followed for a 5-item measure of Group
Cohesiveness (GC) which is predicted to be reduced by higher levels of AC
Roberta also listens to every tape and from her expert judgment she rates each
groups meetings on the same 20 items Those 20 ratings are summed for each of
the 87 2 meetings Now Roberta is interested in evaluating her measure She
wants it to have excellent psychometric properties including reliability and
construct validity

problems engendered by significance testing and why have these remedies not
been widely adopted
B3 (a) There is a debate among the IndustrialOrganizational psychologists on

D) ModeratorsMediators
D1 Moderation and mediation provide different ways to model third variable effects
(a) Please define both of these terms (b) Sketch a conceptual model to show how
each relates to main effects (c) Using variables of your choice please write
hypotheses to reflect both (d) Explain how each is tested analytically
D2 Discuss moderators and mediators Provide an example of how (1) a moderating
variable influences the relationship between the independent and dependent
variable and how (2) a mediating variable influences the relationship between
the independent and dependent variable Describe how you would test for both
moderation and mediation using regression
D3 Many theories in organizational research predict that the effects of one variable
on another are moderated by a third variable Such moderator effects are
typically tested by entering the product of two variables as a predictor after
controlling for the two variables that constitute the product Several researchers
have pointed out that this product is often highly correlated with the squares of
the two constituent variables and have suggested that moderating effects may be
tested after controlling not only for the two constituent variables but also their
squares (eg Cortina 1993 Ganzach 1998 Lubinski amp Humphreys 1990
MacCallum amp Mar 1995) Discuss the strengths and weaknesses of this
approach as compared to methods that use only the product term and its
constituent variables Conclude with recommendations as to when and under
what conditions organizational researchers should test moderator effects with the
squares of the constituent variables in the equation

Y and Z Your first hypothesis posits Z as a mediator of the relationship between
X and Y Your second hypothesis posits Z as a moderator of the relationship
between X and Y Draw the figures depicting each of these hypothesized
relationships and describe (make sure to write regression equations) how you
would test each of these hypotheses
D5 The amount of time and effort that the average person pours into his or her job
has risen steadily over the last two decades such that the average person now is
working one more week per year than the average person in the mid 1970s This
steady increase has fueled research interest in the construct of Job Burnout (JB)
which is an emotional and physical exhaustion associated with ones work
Organizational Stress (OS) the perception of greater demands than available
resources in ones work environment is thought to be one of the chief
antecedents of JB However time spent under OS is thought to make its affects
on JB accumulate or worsen Work Role Withdrawal (WRW) the avoidance of
responsibilities or the deliberate reduction of inputs to ones job is believed to be
the chief consequence of JB

subdomains of management Further demonstrate your understanding of
moderator variables by picking which variable in (a) is the moderator Show the
moderating relationship in an X-Y (or multi-layered) chart Again what elements

moderating effect implied above
E) Multiple Comparisons
E1 In your role as professional colleague you are called upon to advise another doctoral
student about the appropriate use of multiple comparisons and post hoc tests in
analysis of variance Your student colleague already has been introduced to ANOVA
and multiple regression Specifically you are to write out a description of how to test
for differences among the different levels or cells of a categorical variable In your
description you should discuss among other things
a the statistical and philosophical issues raised by post hoc analysis and data
snooping
b the different multiple comparison methods commonly used by researchers to test
for differences among cell means and
c the advantages and disadvantages of each method
Note Your written description will be evaluated based on your demonstrated
competence with the statistical method not on the pedagogy of your explanation
F) Applied Data Analysis
16) Q Your departmental chair is considering a new textbook and has asked for your
recommendations You conduct a well-designed controlled study (details are unimportant) and discover students who use the new book perform 10 better on a standardized subject
matter exam than those using the old book (p = 027) Both books are readily availabe their prices are almost identical and both are equally acceptable to the instructors What is your recommendation to the chair
F1 Attached is the beginning of an article Your task is to write the results section by
1 making up and reporting plausible descriptive statistics that will help the
reader understand the results of the statistical tests you report and the nature of your
sample (Hint this can be presented in the form of a table)
2 describing and defending your choice of appropriate statistical tests of the
hypotheses and the steps that you would go through in carrying out these tests
3 making up and reporting results of these tests that are consistent with your
descriptive statistics and with any information in the rest of the article about the
results found (Hint this can be presented in the form of a table)
4 describing how well these results provide support for the hypotheses You
may want to note any relevant threats to validity here
Be sure to state any assumptions you make
F2 Assume that the Personnel Manager of a local firm Ms B dFlandres hired you to
analyze some data that her assistants had collected over the past several years The
data consist of (a) job performance ratings that were made in June of 1990 and (b)
scores on 25 predictor variables (eg measures of education job experience job
tenure job aptitude personality) that were measured when the individuals were hired
(between April 1987 and May 1988) She had data from only the 110 subjects (60
males and 50 females) who were hired during the period and were still employed by
the firm One objective of your analysis (analyses) is to determine how well the
performance criterion can be predicted by the predictors What strategy would you
use in analyzing the data Describeexplain (b) Is sample size an issue for your
analyses Explain If it is what will you do to deal with problems stemming from
sample size Assume that no additional data can be collected at this time (c) Some
preliminary analyses that you do reveal that five of the predictor variables correlate
(zero-order basis) about 75 with one another Will this influence the analyses that
you use Will it influence the validity of conclusions derived from your proposed
analyses (d) Ms dFlandres is interested in knowing if the predictor variables are
equally effective in predicting the job success of males and females What analysis
or analyses would you do to deal with this issue
F3 Assume that you have been provided with data on 12 conceptually distinct variables
that are moderately correlated with one another at the empirical level The data are
from students in four different college majors ie astronomy (A) biology (B)
criminology (C) and demography (D) The 12 measured variables fall into the
general categories of mental health (tension emotional withdrawal hallucinations
guilt feelings blunted affect and suspiciousness) and job satisfaction (work itself
supervision co-workers pay promotion prospects and working conditions) Your
task is to determine if the individuals in the four college majors differ from one
another on the 12 measured variables
(a) What statistical technique(s) would you use to test for group differences
Explain Be specific about the procedures(s) that you would use
(b) What statistical estimate would you use to estimate the extent to which the
groups differ from one another Be specific
F4 The following statistical table published in a recent issue of Work amp Occupations
was taken from an article discussing variables influencing resistance and citizenship
behaviors in the workplace Resistance behaviors include playing dumb withholding
effort work avoidance subverting particular managers and sabotage Citizenship
behaviors include cooperation engaging in peer training use of insider knowledge to
facilitate production commitment to organizational goals giving extra effort freely
Both measures are global constructs aggregated to the interval level and
standardized
The table reports the results of a series of ordinary least squares regression equations
with standardized coefficients Explain the meaning of the statistics presented What
do these statistics tell us generally about the relationship between resistance
behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows
Anomie Index -standardized interval level measure tapping multiple dimensions
The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)
F5 Researchers collected data from a sample of 350 companies on the following
variables
size (measured as number of employees)
Business Strategy (a nominal variable with 2 response options low-cost provider or
differentiator)
HR Strategy (a nominal variable with 2 response categories High commitment or
low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

I2 A study examined the effects of gender and pre-training motivation on the transfer of
training in terms of improved performance for 123 new industrial managers The
training was on supervisory skills and the dependent variable was based on the
appraisal of the supervisors performance before the training and three months after
the training The performance appraisal data were collected for research purposes
only and resulted in a total transfer score from 1 to 25 with 1 being low Pre-training

mirrors Explain both sides of the debate and then lay out the role of meta-analysis
as you see it within the time span of your career as an academic To do this use
examples of already written (or yet to be written) articles as models
J5 A frequent criticism of non-quantitative research summaries (literature reviews) is
that researchers do not carefully examine how particular research designs might have
affected the statistical outcomes of the studies included in the literature review Meta-
analysis however allows one to statistically examine such effects Assume you are
conducting a meta-analysis of the relationship between leader behaviors and group
productivity Briefly describe the steps you would take in conducting a meta-
analysis What aspects of the original research designs would you examine in your
meta-analysis What steps would you take in gathering and coding data to enhance
the credibility of your analysis

measures is the multi-trait multi-method matrix developed by Campbell and
Fiske (1959) Briefly describe how this matrix is obtained or constructed by a
researcher and then describe how each of the elements of the matrix is used to

and discuss the assumptions of the general linear model Multiple regression
ANOVA and principle components (factor) analysis are based on the general linear
model For each of those three statistical procedures describe and discuss the
following
a The type of data necessary for using the technique appropriately

O1 Contrast Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis
(CFA) Give an example for the appropriate use of each of the above analyses
What is the role of theory in the two factor analyses
IC
O2 Compare and contrast Exploratory Factor Analysis (EFA) with Confirmatory TH
Factor Analysis (CFA) Put more emphasis on their theoretical basis
assumptions usage and limitations
O3 How do exploratory and confirmatory factor analysis differ What are the
advantages and disadvantages of each
O4 Describe the differences between exploratory factor analysis (EFA) and
confirmatory factor analysis (CFA) When would you use one verses another
Are there ways to use EFA in a confirmatory way Can you use CFA in an
exploratory way Also describe the difference in principal components analysis
(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression

information in each matrix and its purpose
(2) For what purpose do researchers use factor analysis Explain In the process
provide a very brief description of a study for which factor analysis would be a
useful data analytic technique

c the type of quantitative output that results from applying the technique
d how a researcher would use the output in his or her research

f the important issues and problems in using the technique
P) Structural Equation Models
P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)
Please comment on these restrictions versus access argument Which side do you
take
What are the strengths of SEM Give some examples
What are the weaknesses of SEM Give some examples

E2 Ipsative measures have become prevalent in organizational behavior research
Ipsative measures ask respondents to answer questions relative to one another
such that the scores for all questions sum to the same constant for all respondents
Examples of ipsative measures include rankings Q-sorts and the allocation of a
fixed number of points (eg 100) across a set of response options Ipsative
measures may be contrasted with absolute measures which ask respondents to
answer questions independently from one another Absolute measures are
exemplified by rating scales using an interval or ratio numeric response format
The relative merits of ipsative and absolute measures have been debated for
decades (eg Cornwell amp Dunlap 1994 Hicks 1970 Johnson Wood amp
Blinkhorn 1988 Saville amp Wilson 1991 1992) yet the fundamental issues
underlying this debate have not been adequately addressed in organizational
behavior research For example measures of organizational culture and values
are often ipsative and some researchers advocate these measures over absolute
measures (eg Meglino amp Ravlin 1987 OReilly Chatman amp Caldwell 1991
Ravlin amp Meglino 1987 see also Rokeach amp Ball-Rokeach 1989) Review the
relative merits of absolute and ipsative measures Based on your review which
form of measurement is most appropriate and why Do your conclusions depend
on the construct being measured If so what types of constructs are best suited to
ipsative measures and what types are best suited to absolute measures Next
apply your conclusions to the measurement of culture and values in
organizations What specific arguments have been advanced in favor of ipsative
measures of culture and values How sound are these arguments Should ipsative
measures be used in the study of organizational culture and values If not how
can absolute measures of culture and values be developed that address the
concerns voiced by advocates of ipsative measures Provide a specific example
of the type of measure you would propose

E5 Suppose Roberta Von Eisenbrick is a researcher interested in the consequences of
AFFECTIVE CONFLICT (AC) in decision-making teams She gets access to a
variety of outcomes assessment committees at each of 87 different schools in
the Dallas Independent School District and gains permission to tape-record two
of their meetings (one in February and one in March) Such committees have
been formed to develop quantitative ways to track pursuit of school goals and
provide accountability to local and state governments These are often divisive
teams with heated meetings because what gets assessed is what usually gets
rewarded After both of these meetings the committee members each
fill out a short questionnaire that contains 20 Likert-type items measuring how
much AC occurred (eg People in our group often get angry with each other)
The individual scores are summed across items then averaged across team
members to come up with a group-level AC score for each of the 87 2
meetings The same procedures are followed for a 5-item measure of Group
Cohesiveness (GC) which is predicted to be reduced by higher levels of AC
Roberta also listens to every tape and from her expert judgment she rates each

it
c What is construct validity Discuss how the (un)reliability of the AC measure
could affect the conclusions one would draw from a study involving it and GC In

problems engendered by significance testing and why have these remedies not
been widely adopted

D) ModeratorsMediators
D1 Moderation and mediation provide different ways to model third variable effects
(a) Please define both of these terms (b) Sketch a conceptual model to show how
each relates to main effects (c) Using variables of your choice please write
hypotheses to reflect both (d) Explain how each is tested analytically
D2 Discuss moderators and mediators Provide an example of how (1) a moderating
variable influences the relationship between the independent and dependent
variable and how (2) a mediating variable influences the relationship between
the independent and dependent variable Describe how you would test for both
moderation and mediation using regression
D3 Many theories in organizational research predict that the effects of one variable
on another are moderated by a third variable Such moderator effects are
typically tested by entering the product of two variables as a predictor after
controlling for the two variables that constitute the product Several researchers
have pointed out that this product is often highly correlated with the squares of
the two constituent variables and have suggested that moderating effects may be
tested after controlling not only for the two constituent variables but also their
squares (eg Cortina 1993 Ganzach 1998 Lubinski amp Humphreys 1990
MacCallum amp Mar 1995) Discuss the strengths and weaknesses of this
approach as compared to methods that use only the product term and its
constituent variables Conclude with recommendations as to when and under
what conditions organizational researchers should test moderator effects with the
squares of the constituent variables in the equation

D4 Assume you are interested in studying relationships amongst three variables X
Y and Z Your first hypothesis posits Z as a mediator of the relationship between
X and Y Your second hypothesis posits Z as a moderator of the relationship
between X and Y Draw the figures depicting each of these hypothesized
relationships and describe (make sure to write regression equations) how you
would test each of these hypotheses
D5 The amount of time and effort that the average person pours into his or her job
has risen steadily over the last two decades such that the average person now is
working one more week per year than the average person in the mid 1970s This
steady increase has fueled research interest in the construct of Job Burnout (JB)
which is an emotional and physical exhaustion associated with ones work
Organizational Stress (OS) the perception of greater demands than available
resources in ones work environment is thought to be one of the chief
antecedents of JB However time spent under OS is thought to make its affects
on JB accumulate or worsen Work Role Withdrawal (WRW) the avoidance of
responsibilities or the deliberate reduction of inputs to ones job is believed to be
the chief consequence of JB
a Formally state these ideas as verbal hypotheses as equations and as a complex
directed graph (circle amp arrow diagram)
b Conceptually what is a mediator Define the term and identify the mediator in
your hypotheses in (a) What elements or steps in a study design (not statistics)
that would be helpful for detecting the mediating relationship that was proposed

subdomains of management Further demonstrate your understanding of
moderator variables by picking which variable in (a) is the moderator Show the
moderating relationship in an X-Y (or multi-layered) chart Again what elements
or steps in a study design (not statistics) would be helpful for detecting the
moderating effect implied above

recommendations You conduct a well-designed controlled study (details are unimportant) and discover students who use the new book perform 10 better on a standardized subject
matter exam than those using the old book (p = 027) Both books are readily availabe their prices are almost identical and both are equally acceptable to the instructors What is your recommendation to the chair
F1 Attached is the beginning of an article Your task is to write the results section by
1 making up and reporting plausible descriptive statistics that will help the
reader understand the results of the statistical tests you report and the nature of your
sample (Hint this can be presented in the form of a table)
2 describing and defending your choice of appropriate statistical tests of the
hypotheses and the steps that you would go through in carrying out these tests
3 making up and reporting results of these tests that are consistent with your
descriptive statistics and with any information in the rest of the article about the
results found (Hint this can be presented in the form of a table)
4 describing how well these results provide support for the hypotheses You
may want to note any relevant threats to validity here
Be sure to state any assumptions you make
F2 Assume that the Personnel Manager of a local firm Ms B dFlandres hired you to
analyze some data that her assistants had collected over the past several years The
data consist of (a) job performance ratings that were made in June of 1990 and (b)
scores on 25 predictor variables (eg measures of education job experience job
tenure job aptitude personality) that were measured when the individuals were hired
(between April 1987 and May 1988) She had data from only the 110 subjects (60
males and 50 females) who were hired during the period and were still employed by
the firm One objective of your analysis (analyses) is to determine how well the
performance criterion can be predicted by the predictors What strategy would you
use in analyzing the data Describeexplain (b) Is sample size an issue for your
analyses Explain If it is what will you do to deal with problems stemming from
sample size Assume that no additional data can be collected at this time (c) Some
preliminary analyses that you do reveal that five of the predictor variables correlate
(zero-order basis) about 75 with one another Will this influence the analyses that
you use Will it influence the validity of conclusions derived from your proposed
analyses (d) Ms dFlandres is interested in knowing if the predictor variables are
equally effective in predicting the job success of males and females What analysis
or analyses would you do to deal with this issue
F3 Assume that you have been provided with data on 12 conceptually distinct variables
that are moderately correlated with one another at the empirical level The data are
from students in four different college majors ie astronomy (A) biology (B)
criminology (C) and demography (D) The 12 measured variables fall into the
general categories of mental health (tension emotional withdrawal hallucinations
guilt feelings blunted affect and suspiciousness) and job satisfaction (work itself
supervision co-workers pay promotion prospects and working conditions) Your
task is to determine if the individuals in the four college majors differ from one
another on the 12 measured variables
(a) What statistical technique(s) would you use to test for group differences
Explain Be specific about the procedures(s) that you would use
(b) What statistical estimate would you use to estimate the extent to which the
groups differ from one another Be specific
F4 The following statistical table published in a recent issue of Work amp Occupations
was taken from an article discussing variables influencing resistance and citizenship
behaviors in the workplace Resistance behaviors include playing dumb withholding
effort work avoidance subverting particular managers and sabotage Citizenship
behaviors include cooperation engaging in peer training use of insider knowledge to
facilitate production commitment to organizational goals giving extra effort freely
Both measures are global constructs aggregated to the interval level and
standardized
The table reports the results of a series of ordinary least squares regression equations
with standardized coefficients Explain the meaning of the statistics presented What
do these statistics tell us generally about the relationship between resistance
behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows
Anomie Index -standardized interval level measure tapping multiple dimensions
The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)
F5 Researchers collected data from a sample of 350 companies on the following
variables
size (measured as number of employees)
Business Strategy (a nominal variable with 2 response options low-cost provider or
differentiator)
HR Strategy (a nominal variable with 2 response categories High commitment or
low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

exploratory way Also describe the difference in principal components analysis
(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression

P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation

Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)
Please comment on these restrictions versus access argument Which side do you
take
What are the strengths of SEM Give some examples
What are the weaknesses of SEM Give some examples

E5 Suppose Roberta Von Eisenbrick is a researcher interested in the consequences of
AFFECTIVE CONFLICT (AC) in decision-making teams She gets access to a
variety of outcomes assessment committees at each of 87 different schools in
the Dallas Independent School District and gains permission to tape-record two
of their meetings (one in February and one in March) Such committees have
been formed to develop quantitative ways to track pursuit of school goals and
provide accountability to local and state governments These are often divisive
teams with heated meetings because what gets assessed is what usually gets
rewarded After both of these meetings the committee members each
fill out a short questionnaire that contains 20 Likert-type items measuring how
much AC occurred (eg People in our group often get angry with each other)
The individual scores are summed across items then averaged across team
members to come up with a group-level AC score for each of the 87 2
meetings The same procedures are followed for a 5-item measure of Group
Cohesiveness (GC) which is predicted to be reduced by higher levels of AC
Roberta also listens to every tape and from her expert judgment she rates each
groups meetings on the same 20 items Those 20 ratings are summed for each of
the 87 2 meetings Now Roberta is interested in evaluating her measure She
wants it to have excellent psychometric properties including reliability and
construct validity

D) ModeratorsMediators
D1 Moderation and mediation provide different ways to model third variable effects
(a) Please define both of these terms (b) Sketch a conceptual model to show how
each relates to main effects (c) Using variables of your choice please write
hypotheses to reflect both (d) Explain how each is tested analytically
D2 Discuss moderators and mediators Provide an example of how (1) a moderating
variable influences the relationship between the independent and dependent
variable and how (2) a mediating variable influences the relationship between
the independent and dependent variable Describe how you would test for both
moderation and mediation using regression
D3 Many theories in organizational research predict that the effects of one variable
on another are moderated by a third variable Such moderator effects are
typically tested by entering the product of two variables as a predictor after
controlling for the two variables that constitute the product Several researchers
have pointed out that this product is often highly correlated with the squares of
the two constituent variables and have suggested that moderating effects may be
tested after controlling not only for the two constituent variables but also their
squares (eg Cortina 1993 Ganzach 1998 Lubinski amp Humphreys 1990
MacCallum amp Mar 1995) Discuss the strengths and weaknesses of this
approach as compared to methods that use only the product term and its
constituent variables Conclude with recommendations as to when and under
what conditions organizational researchers should test moderator effects with the
squares of the constituent variables in the equation

D4 Assume you are interested in studying relationships amongst three variables X
Y and Z Your first hypothesis posits Z as a mediator of the relationship between
X and Y Your second hypothesis posits Z as a moderator of the relationship
between X and Y Draw the figures depicting each of these hypothesized
relationships and describe (make sure to write regression equations) how you
would test each of these hypotheses
D5 The amount of time and effort that the average person pours into his or her job
has risen steadily over the last two decades such that the average person now is
working one more week per year than the average person in the mid 1970s This
steady increase has fueled research interest in the construct of Job Burnout (JB)
which is an emotional and physical exhaustion associated with ones work
Organizational Stress (OS) the perception of greater demands than available
resources in ones work environment is thought to be one of the chief
antecedents of JB However time spent under OS is thought to make its affects
on JB accumulate or worsen Work Role Withdrawal (WRW) the avoidance of
responsibilities or the deliberate reduction of inputs to ones job is believed to be
the chief consequence of JB
a Formally state these ideas as verbal hypotheses as equations and as a complex
directed graph (circle amp arrow diagram)
b Conceptually what is a mediator Define the term and identify the mediator in
your hypotheses in (a) What elements or steps in a study design (not statistics)
that would be helpful for detecting the mediating relationship that was proposed
c What is a moderator What are some of the other names for it within various
subdomains of management Further demonstrate your understanding of
moderator variables by picking which variable in (a) is the moderator Show the
moderating relationship in an X-Y (or multi-layered) chart Again what elements
or steps in a study design (not statistics) would be helpful for detecting the
moderating effect implied above

student about the appropriate use of multiple comparisons and post hoc tests in
analysis of variance Your student colleague already has been introduced to ANOVA
and multiple regression Specifically you are to write out a description of how to test
for differences among the different levels or cells of a categorical variable In your
description you should discuss among other things
a the statistical and philosophical issues raised by post hoc analysis and data
snooping
b the different multiple comparison methods commonly used by researchers to test
for differences among cell means and
c the advantages and disadvantages of each method
Note Your written description will be evaluated based on your demonstrated
competence with the statistical method not on the pedagogy of your explanation
F) Applied Data Analysis
16) Q Your departmental chair is considering a new textbook and has asked for your
recommendations You conduct a well-designed controlled study (details are unimportant) and discover students who use the new book perform 10 better on a standardized subject
matter exam than those using the old book (p = 027) Both books are readily availabe their prices are almost identical and both are equally acceptable to the instructors What is your recommendation to the chair
F1 Attached is the beginning of an article Your task is to write the results section by
1 making up and reporting plausible descriptive statistics that will help the
reader understand the results of the statistical tests you report and the nature of your
sample (Hint this can be presented in the form of a table)
2 describing and defending your choice of appropriate statistical tests of the
hypotheses and the steps that you would go through in carrying out these tests
3 making up and reporting results of these tests that are consistent with your
descriptive statistics and with any information in the rest of the article about the
results found (Hint this can be presented in the form of a table)
4 describing how well these results provide support for the hypotheses You
may want to note any relevant threats to validity here
Be sure to state any assumptions you make
F2 Assume that the Personnel Manager of a local firm Ms B dFlandres hired you to
analyze some data that her assistants had collected over the past several years The
data consist of (a) job performance ratings that were made in June of 1990 and (b)
scores on 25 predictor variables (eg measures of education job experience job
tenure job aptitude personality) that were measured when the individuals were hired
(between April 1987 and May 1988) She had data from only the 110 subjects (60
males and 50 females) who were hired during the period and were still employed by
the firm One objective of your analysis (analyses) is to determine how well the
performance criterion can be predicted by the predictors What strategy would you
use in analyzing the data Describeexplain (b) Is sample size an issue for your
analyses Explain If it is what will you do to deal with problems stemming from
sample size Assume that no additional data can be collected at this time (c) Some
preliminary analyses that you do reveal that five of the predictor variables correlate
(zero-order basis) about 75 with one another Will this influence the analyses that
you use Will it influence the validity of conclusions derived from your proposed
analyses (d) Ms dFlandres is interested in knowing if the predictor variables are
equally effective in predicting the job success of males and females What analysis
or analyses would you do to deal with this issue
F3 Assume that you have been provided with data on 12 conceptually distinct variables
that are moderately correlated with one another at the empirical level The data are
from students in four different college majors ie astronomy (A) biology (B)
criminology (C) and demography (D) The 12 measured variables fall into the
general categories of mental health (tension emotional withdrawal hallucinations
guilt feelings blunted affect and suspiciousness) and job satisfaction (work itself
supervision co-workers pay promotion prospects and working conditions) Your
task is to determine if the individuals in the four college majors differ from one
another on the 12 measured variables
(a) What statistical technique(s) would you use to test for group differences
Explain Be specific about the procedures(s) that you would use
(b) What statistical estimate would you use to estimate the extent to which the
groups differ from one another Be specific
F4 The following statistical table published in a recent issue of Work amp Occupations
was taken from an article discussing variables influencing resistance and citizenship
behaviors in the workplace Resistance behaviors include playing dumb withholding
effort work avoidance subverting particular managers and sabotage Citizenship
behaviors include cooperation engaging in peer training use of insider knowledge to
facilitate production commitment to organizational goals giving extra effort freely
Both measures are global constructs aggregated to the interval level and
standardized
The table reports the results of a series of ordinary least squares regression equations
with standardized coefficients Explain the meaning of the statistics presented What
do these statistics tell us generally about the relationship between resistance
behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows
Anomie Index -standardized interval level measure tapping multiple dimensions
The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)
F5 Researchers collected data from a sample of 350 companies on the following
variables
size (measured as number of employees)
Business Strategy (a nominal variable with 2 response options low-cost provider or
differentiator)
HR Strategy (a nominal variable with 2 response categories High commitment or
low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

interaction What if anything would you do with the sum of squares for the
interaction effect
I2 A study examined the effects of gender and pre-training motivation on the transfer of

J) Meta-analysis
J1 There exist two categories of literature review narrative and quantitative Each
category as typically implemented has certain advantages and disadvantages
Describe the advantages and disadvantages associated with each approach taking
particular care to enumerate the disadvantages associated with quantitative review
Then offer two ways that meta-analysis might be combined with other analytical
techniques to move beyond the focus of bivariate relationships that is typical of meta-
analysis

scientific laws but that meta-analytic research does What are the arguments in favor
of or against this position In what areas of research (if any) has Schmidts
prediction come closest to coming true

sources of error that meta-analysis addresses (b) Discuss the potential contribution
that a meta-analysis can make to theory building in the organizational sciences (c)
Describe the circumstances that you would consider when deciding whether to
perform a meta-analysis

mirrors Explain both sides of the debate and then lay out the role of meta-analysis
as you see it within the time span of your career as an academic To do this use
examples of already written (or yet to be written) articles as models
J5 A frequent criticism of non-quantitative research summaries (literature reviews) is
that researchers do not carefully examine how particular research designs might have
affected the statistical outcomes of the studies included in the literature review Meta-
analysis however allows one to statistically examine such effects Assume you are
conducting a meta-analysis of the relationship between leader behaviors and group
productivity Briefly describe the steps you would take in conducting a meta-
analysis What aspects of the original research designs would you examine in your
meta-analysis What steps would you take in gathering and coding data to enhance
the credibility of your analysis
K) MTMM
K1 One method often used by social scientists to demonstrate the construct validity of
measures is the multi-trait multi-method matrix developed by Campbell and
Fiske (1959) Briefly describe how this matrix is obtained or constructed by a
researcher and then describe how each of the elements of the matrix is used to
demonstrate the reliability andor construct validity of the measure(s)
IC
K2 Describe the logic of the multi-trait multi-method (MTMM) analysis in terms of
the criteria for evaluating the validity of a set of measurement procedures
Interpret the following MTMM in terms of what it might infer about the validity
of the different measurement procedures You may impose any assumptions on
the data you prefer For example you might want to discuss the matrix under the
assumption that traits A B amp C are mutually independent Please justify and
make explicit any assumptions you make

ANOVA and principle components (factor) analysis are based on the general linear
model For each of those three statistical procedures describe and discuss the
following

assumptions usage and limitations
O3 How do exploratory and confirmatory factor analysis differ What are the
advantages and disadvantages of each
O4 Describe the differences between exploratory factor analysis (EFA) and
confirmatory factor analysis (CFA) When would you use one verses another
Are there ways to use EFA in a confirmatory way Can you use CFA in an
exploratory way Also describe the difference in principal components analysis
(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression
O6 The basic factor analysis model can be represented by the matrix algebraic
equation A B = C
(1) What do each of these matrices represent Be specific as to the type of
information in each matrix and its purpose
(2) For what purpose do researchers use factor analysis Explain In the process
provide a very brief description of a study for which factor analysis would be a
useful data analytic technique
O7 Factor analysis is an important statistical technique in organizational research
Describe factor analysis as an analytical tool including the following issues
a the reasons for using factor analysis
b the type of data necessary for using the technique appropriately
c the type of quantitative output that results from applying the technique
d how a researcher would use the output in his or her research
e how confirmatory factor analysis is different from exploratory
f the important issues and problems in using the technique
P) Structural Equation Models
P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

parameter estimate bias in structural equation modeling Structural Equation

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)
Please comment on these restrictions versus access argument Which side do you
take
What are the strengths of SEM Give some examples
What are the weaknesses of SEM Give some examples

of their meetings (one in February and one in March) Such committees have
been formed to develop quantitative ways to track pursuit of school goals and
provide accountability to local and state governments These are often divisive
teams with heated meetings because what gets assessed is what usually gets
rewarded After both of these meetings the committee members each
fill out a short questionnaire that contains 20 Likert-type items measuring how
much AC occurred (eg People in our group often get angry with each other)
The individual scores are summed across items then averaged across team
members to come up with a group-level AC score for each of the 87 2
meetings The same procedures are followed for a 5-item measure of Group
Cohesiveness (GC) which is predicted to be reduced by higher levels of AC
Roberta also listens to every tape and from her expert judgment she rates each
groups meetings on the same 20 items Those 20 ratings are summed for each of
the 87 2 meetings Now Roberta is interested in evaluating her measure She

D) ModeratorsMediators
D1 Moderation and mediation provide different ways to model third variable effects
(a) Please define both of these terms (b) Sketch a conceptual model to show how
each relates to main effects (c) Using variables of your choice please write
hypotheses to reflect both (d) Explain how each is tested analytically
D2 Discuss moderators and mediators Provide an example of how (1) a moderating
variable influences the relationship between the independent and dependent
variable and how (2) a mediating variable influences the relationship between
the independent and dependent variable Describe how you would test for both
moderation and mediation using regression
D3 Many theories in organizational research predict that the effects of one variable
on another are moderated by a third variable Such moderator effects are
typically tested by entering the product of two variables as a predictor after
controlling for the two variables that constitute the product Several researchers
have pointed out that this product is often highly correlated with the squares of
the two constituent variables and have suggested that moderating effects may be
tested after controlling not only for the two constituent variables but also their
squares (eg Cortina 1993 Ganzach 1998 Lubinski amp Humphreys 1990
MacCallum amp Mar 1995) Discuss the strengths and weaknesses of this
approach as compared to methods that use only the product term and its
constituent variables Conclude with recommendations as to when and under
what conditions organizational researchers should test moderator effects with the
squares of the constituent variables in the equation

D4 Assume you are interested in studying relationships amongst three variables X
Y and Z Your first hypothesis posits Z as a mediator of the relationship between
X and Y Your second hypothesis posits Z as a moderator of the relationship
between X and Y Draw the figures depicting each of these hypothesized
relationships and describe (make sure to write regression equations) how you
would test each of these hypotheses
D5 The amount of time and effort that the average person pours into his or her job
has risen steadily over the last two decades such that the average person now is
working one more week per year than the average person in the mid 1970s This
steady increase has fueled research interest in the construct of Job Burnout (JB)
which is an emotional and physical exhaustion associated with ones work
Organizational Stress (OS) the perception of greater demands than available
resources in ones work environment is thought to be one of the chief
antecedents of JB However time spent under OS is thought to make its affects
on JB accumulate or worsen Work Role Withdrawal (WRW) the avoidance of
responsibilities or the deliberate reduction of inputs to ones job is believed to be
the chief consequence of JB
a Formally state these ideas as verbal hypotheses as equations and as a complex
directed graph (circle amp arrow diagram)
b Conceptually what is a mediator Define the term and identify the mediator in
your hypotheses in (a) What elements or steps in a study design (not statistics)
that would be helpful for detecting the mediating relationship that was proposed
c What is a moderator What are some of the other names for it within various
subdomains of management Further demonstrate your understanding of
moderator variables by picking which variable in (a) is the moderator Show the
moderating relationship in an X-Y (or multi-layered) chart Again what elements
or steps in a study design (not statistics) would be helpful for detecting the
moderating effect implied above
E) Multiple Comparisons
E1 In your role as professional colleague you are called upon to advise another doctoral
student about the appropriate use of multiple comparisons and post hoc tests in
analysis of variance Your student colleague already has been introduced to ANOVA
and multiple regression Specifically you are to write out a description of how to test
for differences among the different levels or cells of a categorical variable In your
description you should discuss among other things
a the statistical and philosophical issues raised by post hoc analysis and data
snooping
b the different multiple comparison methods commonly used by researchers to test
for differences among cell means and
c the advantages and disadvantages of each method
Note Your written description will be evaluated based on your demonstrated
competence with the statistical method not on the pedagogy of your explanation
F) Applied Data Analysis
16) Q Your departmental chair is considering a new textbook and has asked for your
recommendations You conduct a well-designed controlled study (details are unimportant) and discover students who use the new book perform 10 better on a standardized subject
matter exam than those using the old book (p = 027) Both books are readily availabe their prices are almost identical and both are equally acceptable to the instructors What is your recommendation to the chair
F1 Attached is the beginning of an article Your task is to write the results section by
1 making up and reporting plausible descriptive statistics that will help the
reader understand the results of the statistical tests you report and the nature of your
sample (Hint this can be presented in the form of a table)
2 describing and defending your choice of appropriate statistical tests of the
hypotheses and the steps that you would go through in carrying out these tests
3 making up and reporting results of these tests that are consistent with your
descriptive statistics and with any information in the rest of the article about the
results found (Hint this can be presented in the form of a table)
4 describing how well these results provide support for the hypotheses You
may want to note any relevant threats to validity here
Be sure to state any assumptions you make
F2 Assume that the Personnel Manager of a local firm Ms B dFlandres hired you to
analyze some data that her assistants had collected over the past several years The
data consist of (a) job performance ratings that were made in June of 1990 and (b)
scores on 25 predictor variables (eg measures of education job experience job
tenure job aptitude personality) that were measured when the individuals were hired
(between April 1987 and May 1988) She had data from only the 110 subjects (60
males and 50 females) who were hired during the period and were still employed by
the firm One objective of your analysis (analyses) is to determine how well the
performance criterion can be predicted by the predictors What strategy would you
use in analyzing the data Describeexplain (b) Is sample size an issue for your
analyses Explain If it is what will you do to deal with problems stemming from
sample size Assume that no additional data can be collected at this time (c) Some
preliminary analyses that you do reveal that five of the predictor variables correlate
(zero-order basis) about 75 with one another Will this influence the analyses that
you use Will it influence the validity of conclusions derived from your proposed
analyses (d) Ms dFlandres is interested in knowing if the predictor variables are
equally effective in predicting the job success of males and females What analysis
or analyses would you do to deal with this issue
F3 Assume that you have been provided with data on 12 conceptually distinct variables
that are moderately correlated with one another at the empirical level The data are
from students in four different college majors ie astronomy (A) biology (B)
criminology (C) and demography (D) The 12 measured variables fall into the
general categories of mental health (tension emotional withdrawal hallucinations
guilt feelings blunted affect and suspiciousness) and job satisfaction (work itself
supervision co-workers pay promotion prospects and working conditions) Your
task is to determine if the individuals in the four college majors differ from one
another on the 12 measured variables
(a) What statistical technique(s) would you use to test for group differences
Explain Be specific about the procedures(s) that you would use
(b) What statistical estimate would you use to estimate the extent to which the
groups differ from one another Be specific
F4 The following statistical table published in a recent issue of Work amp Occupations
was taken from an article discussing variables influencing resistance and citizenship
behaviors in the workplace Resistance behaviors include playing dumb withholding
effort work avoidance subverting particular managers and sabotage Citizenship
behaviors include cooperation engaging in peer training use of insider knowledge to
facilitate production commitment to organizational goals giving extra effort freely
Both measures are global constructs aggregated to the interval level and
standardized
The table reports the results of a series of ordinary least squares regression equations
with standardized coefficients Explain the meaning of the statistics presented What
do these statistics tell us generally about the relationship between resistance
behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows
Anomie Index -standardized interval level measure tapping multiple dimensions
The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)
F5 Researchers collected data from a sample of 350 companies on the following
variables
size (measured as number of employees)
Business Strategy (a nominal variable with 2 response options low-cost provider or
differentiator)
HR Strategy (a nominal variable with 2 response categories High commitment or
low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

I) ANOVA
I1 ANOVA Assume that you have conducted a laboratory experiment in which there
were 3 levels of Factor A (a1 a2 a3) and two levels of Factor B (b1 b2) Assume also
that there were 20 subjects in each cell
(a) Prepare a standard analysis of variance (ANOVA) table that is appropriate for this
design Make certain that you specify all effects and the appropriate degrees of
freedom for each effect If you use any abbreviations in your table make certain that
you specify their meaning
(b) Assume that an initial ANOVA analysis found no evidence of an A X B
interaction What if anything would you do with the sum of squares for the
interaction effect
I2 A study examined the effects of gender and pre-training motivation on the transfer of
training in terms of improved performance for 123 new industrial managers The
training was on supervisory skills and the dependent variable was based on the
appraisal of the supervisors performance before the training and three months after
the training The performance appraisal data were collected for research purposes
only and resulted in a total transfer score from 1 to 25 with 1 being low Pre-training
motivation was based on a 12 item Likert scale with an alpha of 86 Two groups

J) Meta-analysis
J1 There exist two categories of literature review narrative and quantitative Each
category as typically implemented has certain advantages and disadvantages
Describe the advantages and disadvantages associated with each approach taking
particular care to enumerate the disadvantages associated with quantitative review
Then offer two ways that meta-analysis might be combined with other analytical
techniques to move beyond the focus of bivariate relationships that is typical of meta-
analysis
J2 Schmidt has argued that primary research does not allow one to discover general
scientific laws but that meta-analytic research does What are the arguments in favor
of or against this position In what areas of research (if any) has Schmidts
prediction come closest to coming true
J3 The so-called (by Hunter Schmidt and Jackson 1983) state of the art meta-
analysis method attempts to account for various sources of error that might produce
apparent variation in effect sizes across studies (a) Discuss the three most important
sources of error that meta-analysis addresses (b) Discuss the potential contribution
that a meta-analysis can make to theory building in the organizational sciences (c)
Describe the circumstances that you would consider when deciding whether to
perform a meta-analysis
J4 Meta-analysis has been hailed as a miracle cure and criticized as smoke and
mirrors Explain both sides of the debate and then lay out the role of meta-analysis
as you see it within the time span of your career as an academic To do this use
examples of already written (or yet to be written) articles as models
J5 A frequent criticism of non-quantitative research summaries (literature reviews) is
that researchers do not carefully examine how particular research designs might have
affected the statistical outcomes of the studies included in the literature review Meta-
analysis however allows one to statistically examine such effects Assume you are
conducting a meta-analysis of the relationship between leader behaviors and group
productivity Briefly describe the steps you would take in conducting a meta-
analysis What aspects of the original research designs would you examine in your
meta-analysis What steps would you take in gathering and coding data to enhance
the credibility of your analysis
K) MTMM
K1 One method often used by social scientists to demonstrate the construct validity of
measures is the multi-trait multi-method matrix developed by Campbell and
Fiske (1959) Briefly describe how this matrix is obtained or constructed by a
researcher and then describe how each of the elements of the matrix is used to
demonstrate the reliability andor construct validity of the measure(s)
IC
K2 Describe the logic of the multi-trait multi-method (MTMM) analysis in terms of
the criteria for evaluating the validity of a set of measurement procedures
Interpret the following MTMM in terms of what it might infer about the validity
of the different measurement procedures You may impose any assumptions on
the data you prefer For example you might want to discuss the matrix under the
assumption that traits A B amp C are mutually independent Please justify and
make explicit any assumptions you make

model For each of those three statistical procedures describe and discuss the
following

advantages and disadvantages of each
O4 Describe the differences between exploratory factor analysis (EFA) and
confirmatory factor analysis (CFA) When would you use one verses another
Are there ways to use EFA in a confirmatory way Can you use CFA in an
exploratory way Also describe the difference in principal components analysis
(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression
O6 The basic factor analysis model can be represented by the matrix algebraic
equation A B = C

information in each matrix and its purpose
(2) For what purpose do researchers use factor analysis Explain In the process
provide a very brief description of a study for which factor analysis would be a
useful data analytic technique
O7 Factor analysis is an important statistical technique in organizational research
Describe factor analysis as an analytical tool including the following issues
a the reasons for using factor analysis
b the type of data necessary for using the technique appropriately
c the type of quantitative output that results from applying the technique
d how a researcher would use the output in his or her research
e how confirmatory factor analysis is different from exploratory
f the important issues and problems in using the technique
P) Structural Equation Models
P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)
Please comment on these restrictions versus access argument Which side do you
take
What are the strengths of SEM Give some examples
What are the weaknesses of SEM Give some examples

D) ModeratorsMediators
D1 Moderation and mediation provide different ways to model third variable effects
(a) Please define both of these terms (b) Sketch a conceptual model to show how
each relates to main effects (c) Using variables of your choice please write
hypotheses to reflect both (d) Explain how each is tested analytically
D2 Discuss moderators and mediators Provide an example of how (1) a moderating
variable influences the relationship between the independent and dependent
variable and how (2) a mediating variable influences the relationship between
the independent and dependent variable Describe how you would test for both
moderation and mediation using regression
D3 Many theories in organizational research predict that the effects of one variable
on another are moderated by a third variable Such moderator effects are
typically tested by entering the product of two variables as a predictor after
controlling for the two variables that constitute the product Several researchers
have pointed out that this product is often highly correlated with the squares of
the two constituent variables and have suggested that moderating effects may be
tested after controlling not only for the two constituent variables but also their
squares (eg Cortina 1993 Ganzach 1998 Lubinski amp Humphreys 1990
MacCallum amp Mar 1995) Discuss the strengths and weaknesses of this
approach as compared to methods that use only the product term and its
constituent variables Conclude with recommendations as to when and under
what conditions organizational researchers should test moderator effects with the
squares of the constituent variables in the equation

D4 Assume you are interested in studying relationships amongst three variables X
Y and Z Your first hypothesis posits Z as a mediator of the relationship between
X and Y Your second hypothesis posits Z as a moderator of the relationship
between X and Y Draw the figures depicting each of these hypothesized
relationships and describe (make sure to write regression equations) how you
would test each of these hypotheses
D5 The amount of time and effort that the average person pours into his or her job
has risen steadily over the last two decades such that the average person now is
working one more week per year than the average person in the mid 1970s This
steady increase has fueled research interest in the construct of Job Burnout (JB)
which is an emotional and physical exhaustion associated with ones work
Organizational Stress (OS) the perception of greater demands than available
resources in ones work environment is thought to be one of the chief
antecedents of JB However time spent under OS is thought to make its affects
on JB accumulate or worsen Work Role Withdrawal (WRW) the avoidance of
responsibilities or the deliberate reduction of inputs to ones job is believed to be
the chief consequence of JB
a Formally state these ideas as verbal hypotheses as equations and as a complex
directed graph (circle amp arrow diagram)
b Conceptually what is a mediator Define the term and identify the mediator in
your hypotheses in (a) What elements or steps in a study design (not statistics)
that would be helpful for detecting the mediating relationship that was proposed
c What is a moderator What are some of the other names for it within various
subdomains of management Further demonstrate your understanding of
moderator variables by picking which variable in (a) is the moderator Show the
moderating relationship in an X-Y (or multi-layered) chart Again what elements
or steps in a study design (not statistics) would be helpful for detecting the
moderating effect implied above
E) Multiple Comparisons
E1 In your role as professional colleague you are called upon to advise another doctoral
student about the appropriate use of multiple comparisons and post hoc tests in
analysis of variance Your student colleague already has been introduced to ANOVA
and multiple regression Specifically you are to write out a description of how to test
for differences among the different levels or cells of a categorical variable In your
description you should discuss among other things
a the statistical and philosophical issues raised by post hoc analysis and data
snooping
b the different multiple comparison methods commonly used by researchers to test
for differences among cell means and
c the advantages and disadvantages of each method
Note Your written description will be evaluated based on your demonstrated
competence with the statistical method not on the pedagogy of your explanation
F) Applied Data Analysis
16) Q Your departmental chair is considering a new textbook and has asked for your
recommendations You conduct a well-designed controlled study (details are unimportant) and discover students who use the new book perform 10 better on a standardized subject
matter exam than those using the old book (p = 027) Both books are readily availabe their prices are almost identical and both are equally acceptable to the instructors What is your recommendation to the chair
F1 Attached is the beginning of an article Your task is to write the results section by
1 making up and reporting plausible descriptive statistics that will help the
reader understand the results of the statistical tests you report and the nature of your
sample (Hint this can be presented in the form of a table)
2 describing and defending your choice of appropriate statistical tests of the
hypotheses and the steps that you would go through in carrying out these tests
3 making up and reporting results of these tests that are consistent with your
descriptive statistics and with any information in the rest of the article about the
results found (Hint this can be presented in the form of a table)
4 describing how well these results provide support for the hypotheses You
may want to note any relevant threats to validity here
Be sure to state any assumptions you make
F2 Assume that the Personnel Manager of a local firm Ms B dFlandres hired you to
analyze some data that her assistants had collected over the past several years The
data consist of (a) job performance ratings that were made in June of 1990 and (b)
scores on 25 predictor variables (eg measures of education job experience job
tenure job aptitude personality) that were measured when the individuals were hired
(between April 1987 and May 1988) She had data from only the 110 subjects (60
males and 50 females) who were hired during the period and were still employed by
the firm One objective of your analysis (analyses) is to determine how well the
performance criterion can be predicted by the predictors What strategy would you
use in analyzing the data Describeexplain (b) Is sample size an issue for your
analyses Explain If it is what will you do to deal with problems stemming from
sample size Assume that no additional data can be collected at this time (c) Some
preliminary analyses that you do reveal that five of the predictor variables correlate
(zero-order basis) about 75 with one another Will this influence the analyses that
you use Will it influence the validity of conclusions derived from your proposed
analyses (d) Ms dFlandres is interested in knowing if the predictor variables are
equally effective in predicting the job success of males and females What analysis
or analyses would you do to deal with this issue
F3 Assume that you have been provided with data on 12 conceptually distinct variables
that are moderately correlated with one another at the empirical level The data are
from students in four different college majors ie astronomy (A) biology (B)
criminology (C) and demography (D) The 12 measured variables fall into the
general categories of mental health (tension emotional withdrawal hallucinations
guilt feelings blunted affect and suspiciousness) and job satisfaction (work itself
supervision co-workers pay promotion prospects and working conditions) Your
task is to determine if the individuals in the four college majors differ from one
another on the 12 measured variables
(a) What statistical technique(s) would you use to test for group differences
Explain Be specific about the procedures(s) that you would use
(b) What statistical estimate would you use to estimate the extent to which the
groups differ from one another Be specific
F4 The following statistical table published in a recent issue of Work amp Occupations
was taken from an article discussing variables influencing resistance and citizenship
behaviors in the workplace Resistance behaviors include playing dumb withholding
effort work avoidance subverting particular managers and sabotage Citizenship
behaviors include cooperation engaging in peer training use of insider knowledge to
facilitate production commitment to organizational goals giving extra effort freely
Both measures are global constructs aggregated to the interval level and
standardized
The table reports the results of a series of ordinary least squares regression equations
with standardized coefficients Explain the meaning of the statistics presented What
do these statistics tell us generally about the relationship between resistance
behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows
Anomie Index -standardized interval level measure tapping multiple dimensions
The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)
F5 Researchers collected data from a sample of 350 companies on the following
variables
size (measured as number of employees)
Business Strategy (a nominal variable with 2 response options low-cost provider or
differentiator)
HR Strategy (a nominal variable with 2 response categories High commitment or
low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

particular care to enumerate the disadvantages associated with quantitative review
Then offer two ways that meta-analysis might be combined with other analytical
techniques to move beyond the focus of bivariate relationships that is typical of meta-
analysis

scientific laws but that meta-analytic research does What are the arguments in favor
of or against this position In what areas of research (if any) has Schmidts
prediction come closest to coming true

affected the statistical outcomes of the studies included in the literature review Meta-
analysis however allows one to statistically examine such effects Assume you are
conducting a meta-analysis of the relationship between leader behaviors and group
productivity Briefly describe the steps you would take in conducting a meta-

O3 How do exploratory and confirmatory factor analysis differ What are the
advantages and disadvantages of each
O4 Describe the differences between exploratory factor analysis (EFA) and
confirmatory factor analysis (CFA) When would you use one verses another
Are there ways to use EFA in a confirmatory way Can you use CFA in an
exploratory way Also describe the difference in principal components analysis
(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression
O6 The basic factor analysis model can be represented by the matrix algebraic

information in each matrix and its purpose
(2) For what purpose do researchers use factor analysis Explain In the process
provide a very brief description of a study for which factor analysis would be a
useful data analytic technique

c the type of quantitative output that results from applying the technique
d how a researcher would use the output in his or her research

f the important issues and problems in using the technique
P) Structural Equation Models
P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

parameter estimate bias in structural equation modeling Structural Equation

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)
Please comment on these restrictions versus access argument Which side do you
take
What are the strengths of SEM Give some examples
What are the weaknesses of SEM Give some examples

(a) Please define both of these terms (b) Sketch a conceptual model to show how
each relates to main effects (c) Using variables of your choice please write
hypotheses to reflect both (d) Explain how each is tested analytically
D2 Discuss moderators and mediators Provide an example of how (1) a moderating
variable influences the relationship between the independent and dependent
variable and how (2) a mediating variable influences the relationship between
the independent and dependent variable Describe how you would test for both
moderation and mediation using regression
D3 Many theories in organizational research predict that the effects of one variable
on another are moderated by a third variable Such moderator effects are
typically tested by entering the product of two variables as a predictor after
controlling for the two variables that constitute the product Several researchers
have pointed out that this product is often highly correlated with the squares of
the two constituent variables and have suggested that moderating effects may be
tested after controlling not only for the two constituent variables but also their
squares (eg Cortina 1993 Ganzach 1998 Lubinski amp Humphreys 1990
MacCallum amp Mar 1995) Discuss the strengths and weaknesses of this
approach as compared to methods that use only the product term and its
constituent variables Conclude with recommendations as to when and under
what conditions organizational researchers should test moderator effects with the
squares of the constituent variables in the equation

D4 Assume you are interested in studying relationships amongst three variables X
Y and Z Your first hypothesis posits Z as a mediator of the relationship between
X and Y Your second hypothesis posits Z as a moderator of the relationship
between X and Y Draw the figures depicting each of these hypothesized
relationships and describe (make sure to write regression equations) how you
would test each of these hypotheses
D5 The amount of time and effort that the average person pours into his or her job
has risen steadily over the last two decades such that the average person now is
working one more week per year than the average person in the mid 1970s This
steady increase has fueled research interest in the construct of Job Burnout (JB)
which is an emotional and physical exhaustion associated with ones work
Organizational Stress (OS) the perception of greater demands than available
resources in ones work environment is thought to be one of the chief
antecedents of JB However time spent under OS is thought to make its affects
on JB accumulate or worsen Work Role Withdrawal (WRW) the avoidance of
responsibilities or the deliberate reduction of inputs to ones job is believed to be
the chief consequence of JB
a Formally state these ideas as verbal hypotheses as equations and as a complex
directed graph (circle amp arrow diagram)
b Conceptually what is a mediator Define the term and identify the mediator in
your hypotheses in (a) What elements or steps in a study design (not statistics)
that would be helpful for detecting the mediating relationship that was proposed
c What is a moderator What are some of the other names for it within various
subdomains of management Further demonstrate your understanding of
moderator variables by picking which variable in (a) is the moderator Show the
moderating relationship in an X-Y (or multi-layered) chart Again what elements
or steps in a study design (not statistics) would be helpful for detecting the
moderating effect implied above

for differences among cell means and
c the advantages and disadvantages of each method
Note Your written description will be evaluated based on your demonstrated
competence with the statistical method not on the pedagogy of your explanation
F) Applied Data Analysis
16) Q Your departmental chair is considering a new textbook and has asked for your
recommendations You conduct a well-designed controlled study (details are unimportant) and discover students who use the new book perform 10 better on a standardized subject
matter exam than those using the old book (p = 027) Both books are readily availabe their prices are almost identical and both are equally acceptable to the instructors What is your recommendation to the chair
F1 Attached is the beginning of an article Your task is to write the results section by
1 making up and reporting plausible descriptive statistics that will help the
reader understand the results of the statistical tests you report and the nature of your
sample (Hint this can be presented in the form of a table)
2 describing and defending your choice of appropriate statistical tests of the
hypotheses and the steps that you would go through in carrying out these tests
3 making up and reporting results of these tests that are consistent with your
descriptive statistics and with any information in the rest of the article about the
results found (Hint this can be presented in the form of a table)
4 describing how well these results provide support for the hypotheses You
may want to note any relevant threats to validity here
Be sure to state any assumptions you make
F2 Assume that the Personnel Manager of a local firm Ms B dFlandres hired you to
analyze some data that her assistants had collected over the past several years The
data consist of (a) job performance ratings that were made in June of 1990 and (b)
scores on 25 predictor variables (eg measures of education job experience job
tenure job aptitude personality) that were measured when the individuals were hired
(between April 1987 and May 1988) She had data from only the 110 subjects (60
males and 50 females) who were hired during the period and were still employed by
the firm One objective of your analysis (analyses) is to determine how well the
performance criterion can be predicted by the predictors What strategy would you
use in analyzing the data Describeexplain (b) Is sample size an issue for your
analyses Explain If it is what will you do to deal with problems stemming from
sample size Assume that no additional data can be collected at this time (c) Some
preliminary analyses that you do reveal that five of the predictor variables correlate
(zero-order basis) about 75 with one another Will this influence the analyses that
you use Will it influence the validity of conclusions derived from your proposed
analyses (d) Ms dFlandres is interested in knowing if the predictor variables are
equally effective in predicting the job success of males and females What analysis
or analyses would you do to deal with this issue
F3 Assume that you have been provided with data on 12 conceptually distinct variables
that are moderately correlated with one another at the empirical level The data are
from students in four different college majors ie astronomy (A) biology (B)
criminology (C) and demography (D) The 12 measured variables fall into the
general categories of mental health (tension emotional withdrawal hallucinations
guilt feelings blunted affect and suspiciousness) and job satisfaction (work itself
supervision co-workers pay promotion prospects and working conditions) Your
task is to determine if the individuals in the four college majors differ from one
another on the 12 measured variables
(a) What statistical technique(s) would you use to test for group differences
Explain Be specific about the procedures(s) that you would use
(b) What statistical estimate would you use to estimate the extent to which the
groups differ from one another Be specific
F4 The following statistical table published in a recent issue of Work amp Occupations
was taken from an article discussing variables influencing resistance and citizenship
behaviors in the workplace Resistance behaviors include playing dumb withholding
effort work avoidance subverting particular managers and sabotage Citizenship
behaviors include cooperation engaging in peer training use of insider knowledge to
facilitate production commitment to organizational goals giving extra effort freely
Both measures are global constructs aggregated to the interval level and
standardized
The table reports the results of a series of ordinary least squares regression equations
with standardized coefficients Explain the meaning of the statistics presented What
do these statistics tell us generally about the relationship between resistance
behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows
Anomie Index -standardized interval level measure tapping multiple dimensions
The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)
F5 Researchers collected data from a sample of 350 companies on the following
variables
size (measured as number of employees)
Business Strategy (a nominal variable with 2 response options low-cost provider or
differentiator)
HR Strategy (a nominal variable with 2 response categories High commitment or
low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

particular care to enumerate the disadvantages associated with quantitative review
Then offer two ways that meta-analysis might be combined with other analytical
techniques to move beyond the focus of bivariate relationships that is typical of meta-
analysis

scientific laws but that meta-analytic research does What are the arguments in favor
of or against this position In what areas of research (if any) has Schmidts
prediction come closest to coming true

analysis method attempts to account for various sources of error that might produce
apparent variation in effect sizes across studies (a) Discuss the three most important
sources of error that meta-analysis addresses (b) Discuss the potential contribution
that a meta-analysis can make to theory building in the organizational sciences (c)
Describe the circumstances that you would consider when deciding whether to
perform a meta-analysis

confirmatory factor analysis (CFA) When would you use one verses another
Are there ways to use EFA in a confirmatory way Can you use CFA in an
exploratory way Also describe the difference in principal components analysis
(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression
O6 The basic factor analysis model can be represented by the matrix algebraic
equation A B = C

information in each matrix and its purpose
(2) For what purpose do researchers use factor analysis Explain In the process
provide a very brief description of a study for which factor analysis would be a
useful data analytic technique
O7 Factor analysis is an important statistical technique in organizational research
Describe factor analysis as an analytical tool including the following issues
a the reasons for using factor analysis
b the type of data necessary for using the technique appropriately
c the type of quantitative output that results from applying the technique
d how a researcher would use the output in his or her research

f the important issues and problems in using the technique
P) Structural Equation Models
P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

parameter estimate bias in structural equation modeling Structural Equation

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)
Please comment on these restrictions versus access argument Which side do you
take
What are the strengths of SEM Give some examples
What are the weaknesses of SEM Give some examples

D) ModeratorsMediators
D1 Moderation and mediation provide different ways to model third variable effects
(a) Please define both of these terms (b) Sketch a conceptual model to show how
each relates to main effects (c) Using variables of your choice please write
hypotheses to reflect both (d) Explain how each is tested analytically
D2 Discuss moderators and mediators Provide an example of how (1) a moderating
variable influences the relationship between the independent and dependent
variable and how (2) a mediating variable influences the relationship between
the independent and dependent variable Describe how you would test for both
moderation and mediation using regression
D3 Many theories in organizational research predict that the effects of one variable
on another are moderated by a third variable Such moderator effects are
typically tested by entering the product of two variables as a predictor after
controlling for the two variables that constitute the product Several researchers
have pointed out that this product is often highly correlated with the squares of
the two constituent variables and have suggested that moderating effects may be
tested after controlling not only for the two constituent variables but also their
squares (eg Cortina 1993 Ganzach 1998 Lubinski amp Humphreys 1990
MacCallum amp Mar 1995) Discuss the strengths and weaknesses of this
approach as compared to methods that use only the product term and its
constituent variables Conclude with recommendations as to when and under
what conditions organizational researchers should test moderator effects with the
squares of the constituent variables in the equation

D4 Assume you are interested in studying relationships amongst three variables X
Y and Z Your first hypothesis posits Z as a mediator of the relationship between
X and Y Your second hypothesis posits Z as a moderator of the relationship
between X and Y Draw the figures depicting each of these hypothesized
relationships and describe (make sure to write regression equations) how you
would test each of these hypotheses
D5 The amount of time and effort that the average person pours into his or her job
has risen steadily over the last two decades such that the average person now is
working one more week per year than the average person in the mid 1970s This
steady increase has fueled research interest in the construct of Job Burnout (JB)
which is an emotional and physical exhaustion associated with ones work
Organizational Stress (OS) the perception of greater demands than available
resources in ones work environment is thought to be one of the chief
antecedents of JB However time spent under OS is thought to make its affects
on JB accumulate or worsen Work Role Withdrawal (WRW) the avoidance of
responsibilities or the deliberate reduction of inputs to ones job is believed to be
the chief consequence of JB
a Formally state these ideas as verbal hypotheses as equations and as a complex
directed graph (circle amp arrow diagram)
b Conceptually what is a mediator Define the term and identify the mediator in
your hypotheses in (a) What elements or steps in a study design (not statistics)
that would be helpful for detecting the mediating relationship that was proposed
c What is a moderator What are some of the other names for it within various
subdomains of management Further demonstrate your understanding of
moderator variables by picking which variable in (a) is the moderator Show the
moderating relationship in an X-Y (or multi-layered) chart Again what elements
or steps in a study design (not statistics) would be helpful for detecting the
moderating effect implied above
E) Multiple Comparisons
E1 In your role as professional colleague you are called upon to advise another doctoral
student about the appropriate use of multiple comparisons and post hoc tests in
analysis of variance Your student colleague already has been introduced to ANOVA
and multiple regression Specifically you are to write out a description of how to test
for differences among the different levels or cells of a categorical variable In your
description you should discuss among other things
a the statistical and philosophical issues raised by post hoc analysis and data
snooping
b the different multiple comparison methods commonly used by researchers to test
for differences among cell means and
c the advantages and disadvantages of each method
Note Your written description will be evaluated based on your demonstrated
competence with the statistical method not on the pedagogy of your explanation
F) Applied Data Analysis
16) Q Your departmental chair is considering a new textbook and has asked for your
recommendations You conduct a well-designed controlled study (details are unimportant) and discover students who use the new book perform 10 better on a standardized subject
matter exam than those using the old book (p = 027) Both books are readily availabe their prices are almost identical and both are equally acceptable to the instructors What is your recommendation to the chair
F1 Attached is the beginning of an article Your task is to write the results section by
1 making up and reporting plausible descriptive statistics that will help the
reader understand the results of the statistical tests you report and the nature of your
sample (Hint this can be presented in the form of a table)
2 describing and defending your choice of appropriate statistical tests of the
hypotheses and the steps that you would go through in carrying out these tests
3 making up and reporting results of these tests that are consistent with your
descriptive statistics and with any information in the rest of the article about the
results found (Hint this can be presented in the form of a table)
4 describing how well these results provide support for the hypotheses You
may want to note any relevant threats to validity here
Be sure to state any assumptions you make
F2 Assume that the Personnel Manager of a local firm Ms B dFlandres hired you to
analyze some data that her assistants had collected over the past several years The
data consist of (a) job performance ratings that were made in June of 1990 and (b)
scores on 25 predictor variables (eg measures of education job experience job
tenure job aptitude personality) that were measured when the individuals were hired
(between April 1987 and May 1988) She had data from only the 110 subjects (60
males and 50 females) who were hired during the period and were still employed by
the firm One objective of your analysis (analyses) is to determine how well the
performance criterion can be predicted by the predictors What strategy would you
use in analyzing the data Describeexplain (b) Is sample size an issue for your
analyses Explain If it is what will you do to deal with problems stemming from
sample size Assume that no additional data can be collected at this time (c) Some
preliminary analyses that you do reveal that five of the predictor variables correlate
(zero-order basis) about 75 with one another Will this influence the analyses that
you use Will it influence the validity of conclusions derived from your proposed
analyses (d) Ms dFlandres is interested in knowing if the predictor variables are
equally effective in predicting the job success of males and females What analysis
or analyses would you do to deal with this issue
F3 Assume that you have been provided with data on 12 conceptually distinct variables
that are moderately correlated with one another at the empirical level The data are
from students in four different college majors ie astronomy (A) biology (B)
criminology (C) and demography (D) The 12 measured variables fall into the
general categories of mental health (tension emotional withdrawal hallucinations
guilt feelings blunted affect and suspiciousness) and job satisfaction (work itself
supervision co-workers pay promotion prospects and working conditions) Your
task is to determine if the individuals in the four college majors differ from one
another on the 12 measured variables
(a) What statistical technique(s) would you use to test for group differences
Explain Be specific about the procedures(s) that you would use
(b) What statistical estimate would you use to estimate the extent to which the
groups differ from one another Be specific
F4 The following statistical table published in a recent issue of Work amp Occupations
was taken from an article discussing variables influencing resistance and citizenship
behaviors in the workplace Resistance behaviors include playing dumb withholding
effort work avoidance subverting particular managers and sabotage Citizenship
behaviors include cooperation engaging in peer training use of insider knowledge to
facilitate production commitment to organizational goals giving extra effort freely
Both measures are global constructs aggregated to the interval level and
standardized
The table reports the results of a series of ordinary least squares regression equations
with standardized coefficients Explain the meaning of the statistics presented What
do these statistics tell us generally about the relationship between resistance
behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows
Anomie Index -standardized interval level measure tapping multiple dimensions
The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)
F5 Researchers collected data from a sample of 350 companies on the following
variables
size (measured as number of employees)
Business Strategy (a nominal variable with 2 response options low-cost provider or
differentiator)
HR Strategy (a nominal variable with 2 response categories High commitment or
low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

category as typically implemented has certain advantages and disadvantages
Describe the advantages and disadvantages associated with each approach taking
particular care to enumerate the disadvantages associated with quantitative review
Then offer two ways that meta-analysis might be combined with other analytical
techniques to move beyond the focus of bivariate relationships that is typical of meta-
analysis

scientific laws but that meta-analytic research does What are the arguments in favor
of or against this position In what areas of research (if any) has Schmidts
prediction come closest to coming true

mirrors Explain both sides of the debate and then lay out the role of meta-analysis
as you see it within the time span of your career as an academic To do this use
examples of already written (or yet to be written) articles as models
J5 A frequent criticism of non-quantitative research summaries (literature reviews) is
that researchers do not carefully examine how particular research designs might have
affected the statistical outcomes of the studies included in the literature review Meta-
analysis however allows one to statistically examine such effects Assume you are
conducting a meta-analysis of the relationship between leader behaviors and group
productivity Briefly describe the steps you would take in conducting a meta-
analysis What aspects of the original research designs would you examine in your
meta-analysis What steps would you take in gathering and coding data to enhance
the credibility of your analysis

measures is the multi-trait multi-method matrix developed by Campbell and
Fiske (1959) Briefly describe how this matrix is obtained or constructed by a
researcher and then describe how each of the elements of the matrix is used to
demonstrate the reliability andor construct validity of the measure(s)

O3 How do exploratory and confirmatory factor analysis differ What are the
advantages and disadvantages of each
O4 Describe the differences between exploratory factor analysis (EFA) and
confirmatory factor analysis (CFA) When would you use one verses another
Are there ways to use EFA in a confirmatory way Can you use CFA in an
exploratory way Also describe the difference in principal components analysis
(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression
O6 The basic factor analysis model can be represented by the matrix algebraic
equation A B = C

information in each matrix and its purpose
(2) For what purpose do researchers use factor analysis Explain In the process
provide a very brief description of a study for which factor analysis would be a
useful data analytic technique
O7 Factor analysis is an important statistical technique in organizational research

a the reasons for using factor analysis
b the type of data necessary for using the technique appropriately
c the type of quantitative output that results from applying the technique
d how a researcher would use the output in his or her research

f the important issues and problems in using the technique
P) Structural Equation Models
P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)
Please comment on these restrictions versus access argument Which side do you
take
What are the strengths of SEM Give some examples
What are the weaknesses of SEM Give some examples

D4 Assume you are interested in studying relationships amongst three variables X
Y and Z Your first hypothesis posits Z as a mediator of the relationship between
X and Y Your second hypothesis posits Z as a moderator of the relationship
between X and Y Draw the figures depicting each of these hypothesized
relationships and describe (make sure to write regression equations) how you
would test each of these hypotheses
D5 The amount of time and effort that the average person pours into his or her job
has risen steadily over the last two decades such that the average person now is
working one more week per year than the average person in the mid 1970s This
steady increase has fueled research interest in the construct of Job Burnout (JB)
which is an emotional and physical exhaustion associated with ones work
Organizational Stress (OS) the perception of greater demands than available
resources in ones work environment is thought to be one of the chief
antecedents of JB However time spent under OS is thought to make its affects
on JB accumulate or worsen Work Role Withdrawal (WRW) the avoidance of
responsibilities or the deliberate reduction of inputs to ones job is believed to be
the chief consequence of JB
a Formally state these ideas as verbal hypotheses as equations and as a complex
directed graph (circle amp arrow diagram)
b Conceptually what is a mediator Define the term and identify the mediator in
your hypotheses in (a) What elements or steps in a study design (not statistics)
that would be helpful for detecting the mediating relationship that was proposed
c What is a moderator What are some of the other names for it within various
subdomains of management Further demonstrate your understanding of
moderator variables by picking which variable in (a) is the moderator Show the
moderating relationship in an X-Y (or multi-layered) chart Again what elements
or steps in a study design (not statistics) would be helpful for detecting the
moderating effect implied above
E) Multiple Comparisons
E1 In your role as professional colleague you are called upon to advise another doctoral
student about the appropriate use of multiple comparisons and post hoc tests in
analysis of variance Your student colleague already has been introduced to ANOVA
and multiple regression Specifically you are to write out a description of how to test
for differences among the different levels or cells of a categorical variable In your
description you should discuss among other things
a the statistical and philosophical issues raised by post hoc analysis and data
snooping
b the different multiple comparison methods commonly used by researchers to test
for differences among cell means and
c the advantages and disadvantages of each method
Note Your written description will be evaluated based on your demonstrated
competence with the statistical method not on the pedagogy of your explanation
F) Applied Data Analysis
16) Q Your departmental chair is considering a new textbook and has asked for your
recommendations You conduct a well-designed controlled study (details are unimportant) and discover students who use the new book perform 10 better on a standardized subject
matter exam than those using the old book (p = 027) Both books are readily availabe their prices are almost identical and both are equally acceptable to the instructors What is your recommendation to the chair
F1 Attached is the beginning of an article Your task is to write the results section by
1 making up and reporting plausible descriptive statistics that will help the
reader understand the results of the statistical tests you report and the nature of your
sample (Hint this can be presented in the form of a table)
2 describing and defending your choice of appropriate statistical tests of the
hypotheses and the steps that you would go through in carrying out these tests
3 making up and reporting results of these tests that are consistent with your
descriptive statistics and with any information in the rest of the article about the
results found (Hint this can be presented in the form of a table)
4 describing how well these results provide support for the hypotheses You
may want to note any relevant threats to validity here
Be sure to state any assumptions you make
F2 Assume that the Personnel Manager of a local firm Ms B dFlandres hired you to
analyze some data that her assistants had collected over the past several years The
data consist of (a) job performance ratings that were made in June of 1990 and (b)
scores on 25 predictor variables (eg measures of education job experience job
tenure job aptitude personality) that were measured when the individuals were hired
(between April 1987 and May 1988) She had data from only the 110 subjects (60
males and 50 females) who were hired during the period and were still employed by
the firm One objective of your analysis (analyses) is to determine how well the
performance criterion can be predicted by the predictors What strategy would you
use in analyzing the data Describeexplain (b) Is sample size an issue for your
analyses Explain If it is what will you do to deal with problems stemming from
sample size Assume that no additional data can be collected at this time (c) Some
preliminary analyses that you do reveal that five of the predictor variables correlate
(zero-order basis) about 75 with one another Will this influence the analyses that
you use Will it influence the validity of conclusions derived from your proposed
analyses (d) Ms dFlandres is interested in knowing if the predictor variables are
equally effective in predicting the job success of males and females What analysis
or analyses would you do to deal with this issue
F3 Assume that you have been provided with data on 12 conceptually distinct variables
that are moderately correlated with one another at the empirical level The data are
from students in four different college majors ie astronomy (A) biology (B)
criminology (C) and demography (D) The 12 measured variables fall into the
general categories of mental health (tension emotional withdrawal hallucinations
guilt feelings blunted affect and suspiciousness) and job satisfaction (work itself
supervision co-workers pay promotion prospects and working conditions) Your
task is to determine if the individuals in the four college majors differ from one
another on the 12 measured variables
(a) What statistical technique(s) would you use to test for group differences
Explain Be specific about the procedures(s) that you would use
(b) What statistical estimate would you use to estimate the extent to which the
groups differ from one another Be specific
F4 The following statistical table published in a recent issue of Work amp Occupations
was taken from an article discussing variables influencing resistance and citizenship
behaviors in the workplace Resistance behaviors include playing dumb withholding
effort work avoidance subverting particular managers and sabotage Citizenship
behaviors include cooperation engaging in peer training use of insider knowledge to
facilitate production commitment to organizational goals giving extra effort freely
Both measures are global constructs aggregated to the interval level and
standardized
The table reports the results of a series of ordinary least squares regression equations
with standardized coefficients Explain the meaning of the statistics presented What
do these statistics tell us generally about the relationship between resistance
behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows
Anomie Index -standardized interval level measure tapping multiple dimensions
The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)
F5 Researchers collected data from a sample of 350 companies on the following
variables
size (measured as number of employees)
Business Strategy (a nominal variable with 2 response options low-cost provider or
differentiator)
HR Strategy (a nominal variable with 2 response categories High commitment or
low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

category as typically implemented has certain advantages and disadvantages
Describe the advantages and disadvantages associated with each approach taking
particular care to enumerate the disadvantages associated with quantitative review
Then offer two ways that meta-analysis might be combined with other analytical
techniques to move beyond the focus of bivariate relationships that is typical of meta-
analysis

scientific laws but that meta-analytic research does What are the arguments in favor
of or against this position In what areas of research (if any) has Schmidts
prediction come closest to coming true

mirrors Explain both sides of the debate and then lay out the role of meta-analysis
as you see it within the time span of your career as an academic To do this use
examples of already written (or yet to be written) articles as models
J5 A frequent criticism of non-quantitative research summaries (literature reviews) is
that researchers do not carefully examine how particular research designs might have
affected the statistical outcomes of the studies included in the literature review Meta-
analysis however allows one to statistically examine such effects Assume you are
conducting a meta-analysis of the relationship between leader behaviors and group
productivity Briefly describe the steps you would take in conducting a meta-
analysis What aspects of the original research designs would you examine in your
meta-analysis What steps would you take in gathering and coding data to enhance
the credibility of your analysis
K) MTMM

measures is the multi-trait multi-method matrix developed by Campbell and
Fiske (1959) Briefly describe how this matrix is obtained or constructed by a
researcher and then describe how each of the elements of the matrix is used to
demonstrate the reliability andor construct validity of the measure(s)
IC
K2 Describe the logic of the multi-trait multi-method (MTMM) analysis in terms of
the criteria for evaluating the validity of a set of measurement procedures
Interpret the following MTMM in terms of what it might infer about the validity

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)

c the advantages and disadvantages of each method
Note Your written description will be evaluated based on your demonstrated
competence with the statistical method not on the pedagogy of your explanation
F) Applied Data Analysis
16) Q Your departmental chair is considering a new textbook and has asked for your
recommendations You conduct a well-designed controlled study (details are unimportant) and discover students who use the new book perform 10 better on a standardized subject
matter exam than those using the old book (p = 027) Both books are readily availabe their prices are almost identical and both are equally acceptable to the instructors What is your recommendation to the chair
F1 Attached is the beginning of an article Your task is to write the results section by
1 making up and reporting plausible descriptive statistics that will help the
reader understand the results of the statistical tests you report and the nature of your
sample (Hint this can be presented in the form of a table)
2 describing and defending your choice of appropriate statistical tests of the
hypotheses and the steps that you would go through in carrying out these tests
3 making up and reporting results of these tests that are consistent with your
descriptive statistics and with any information in the rest of the article about the
results found (Hint this can be presented in the form of a table)
4 describing how well these results provide support for the hypotheses You
may want to note any relevant threats to validity here
Be sure to state any assumptions you make
F2 Assume that the Personnel Manager of a local firm Ms B dFlandres hired you to
analyze some data that her assistants had collected over the past several years The
data consist of (a) job performance ratings that were made in June of 1990 and (b)
scores on 25 predictor variables (eg measures of education job experience job
tenure job aptitude personality) that were measured when the individuals were hired
(between April 1987 and May 1988) She had data from only the 110 subjects (60
males and 50 females) who were hired during the period and were still employed by
the firm One objective of your analysis (analyses) is to determine how well the
performance criterion can be predicted by the predictors What strategy would you
use in analyzing the data Describeexplain (b) Is sample size an issue for your
analyses Explain If it is what will you do to deal with problems stemming from
sample size Assume that no additional data can be collected at this time (c) Some
preliminary analyses that you do reveal that five of the predictor variables correlate
(zero-order basis) about 75 with one another Will this influence the analyses that
you use Will it influence the validity of conclusions derived from your proposed
analyses (d) Ms dFlandres is interested in knowing if the predictor variables are
equally effective in predicting the job success of males and females What analysis
or analyses would you do to deal with this issue
F3 Assume that you have been provided with data on 12 conceptually distinct variables
that are moderately correlated with one another at the empirical level The data are
from students in four different college majors ie astronomy (A) biology (B)
criminology (C) and demography (D) The 12 measured variables fall into the
general categories of mental health (tension emotional withdrawal hallucinations
guilt feelings blunted affect and suspiciousness) and job satisfaction (work itself
supervision co-workers pay promotion prospects and working conditions) Your
task is to determine if the individuals in the four college majors differ from one
another on the 12 measured variables
(a) What statistical technique(s) would you use to test for group differences
Explain Be specific about the procedures(s) that you would use
(b) What statistical estimate would you use to estimate the extent to which the
groups differ from one another Be specific
F4 The following statistical table published in a recent issue of Work amp Occupations
was taken from an article discussing variables influencing resistance and citizenship
behaviors in the workplace Resistance behaviors include playing dumb withholding
effort work avoidance subverting particular managers and sabotage Citizenship
behaviors include cooperation engaging in peer training use of insider knowledge to
facilitate production commitment to organizational goals giving extra effort freely
Both measures are global constructs aggregated to the interval level and
standardized
The table reports the results of a series of ordinary least squares regression equations
with standardized coefficients Explain the meaning of the statistics presented What
do these statistics tell us generally about the relationship between resistance
behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows
Anomie Index -standardized interval level measure tapping multiple dimensions
The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)
F5 Researchers collected data from a sample of 350 companies on the following
variables
size (measured as number of employees)
Business Strategy (a nominal variable with 2 response options low-cost provider or
differentiator)
HR Strategy (a nominal variable with 2 response categories High commitment or
low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

design Make certain that you specify all effects and the appropriate degrees of
freedom for each effect If you use any abbreviations in your table make certain that
you specify their meaning
(b) Assume that an initial ANOVA analysis found no evidence of an A X B
interaction What if anything would you do with the sum of squares for the
interaction effect
I2 A study examined the effects of gender and pre-training motivation on the transfer of
training in terms of improved performance for 123 new industrial managers The
training was on supervisory skills and the dependent variable was based on the
appraisal of the supervisors performance before the training and three months after
the training The performance appraisal data were collected for research purposes
only and resulted in a total transfer score from 1 to 25 with 1 being low Pre-training
motivation was based on a 12 item Likert scale with an alpha of 86 Two groups

J) Meta-analysis
J1 There exist two categories of literature review narrative and quantitative Each
category as typically implemented has certain advantages and disadvantages
Describe the advantages and disadvantages associated with each approach taking
particular care to enumerate the disadvantages associated with quantitative review
Then offer two ways that meta-analysis might be combined with other analytical
techniques to move beyond the focus of bivariate relationships that is typical of meta-
analysis

scientific laws but that meta-analytic research does What are the arguments in favor
of or against this position In what areas of research (if any) has Schmidts
prediction come closest to coming true

analysis method attempts to account for various sources of error that might produce
apparent variation in effect sizes across studies (a) Discuss the three most important
sources of error that meta-analysis addresses (b) Discuss the potential contribution
that a meta-analysis can make to theory building in the organizational sciences (c)
Describe the circumstances that you would consider when deciding whether to
perform a meta-analysis

mirrors Explain both sides of the debate and then lay out the role of meta-analysis
as you see it within the time span of your career as an academic To do this use
examples of already written (or yet to be written) articles as models
J5 A frequent criticism of non-quantitative research summaries (literature reviews) is
that researchers do not carefully examine how particular research designs might have
affected the statistical outcomes of the studies included in the literature review Meta-
analysis however allows one to statistically examine such effects Assume you are
conducting a meta-analysis of the relationship between leader behaviors and group
productivity Briefly describe the steps you would take in conducting a meta-
analysis What aspects of the original research designs would you examine in your
meta-analysis What steps would you take in gathering and coding data to enhance
the credibility of your analysis
K) MTMM
K1 One method often used by social scientists to demonstrate the construct validity of
measures is the multi-trait multi-method matrix developed by Campbell and
Fiske (1959) Briefly describe how this matrix is obtained or constructed by a
researcher and then describe how each of the elements of the matrix is used to
demonstrate the reliability andor construct validity of the measure(s)
IC
K2 Describe the logic of the multi-trait multi-method (MTMM) analysis in terms of
the criteria for evaluating the validity of a set of measurement procedures
Interpret the following MTMM in terms of what it might infer about the validity
of the different measurement procedures You may impose any assumptions on
the data you prefer For example you might want to discuss the matrix under the
assumption that traits A B amp C are mutually independent Please justify and
make explicit any assumptions you make

Be sure to state any assumptions you make
F2 Assume that the Personnel Manager of a local firm Ms B dFlandres hired you to
analyze some data that her assistants had collected over the past several years The
data consist of (a) job performance ratings that were made in June of 1990 and (b)
scores on 25 predictor variables (eg measures of education job experience job
tenure job aptitude personality) that were measured when the individuals were hired
(between April 1987 and May 1988) She had data from only the 110 subjects (60
males and 50 females) who were hired during the period and were still employed by
the firm One objective of your analysis (analyses) is to determine how well the
performance criterion can be predicted by the predictors What strategy would you
use in analyzing the data Describeexplain (b) Is sample size an issue for your
analyses Explain If it is what will you do to deal with problems stemming from
sample size Assume that no additional data can be collected at this time (c) Some
preliminary analyses that you do reveal that five of the predictor variables correlate
(zero-order basis) about 75 with one another Will this influence the analyses that
you use Will it influence the validity of conclusions derived from your proposed
analyses (d) Ms dFlandres is interested in knowing if the predictor variables are
equally effective in predicting the job success of males and females What analysis
or analyses would you do to deal with this issue
F3 Assume that you have been provided with data on 12 conceptually distinct variables
that are moderately correlated with one another at the empirical level The data are
from students in four different college majors ie astronomy (A) biology (B)
criminology (C) and demography (D) The 12 measured variables fall into the
general categories of mental health (tension emotional withdrawal hallucinations
guilt feelings blunted affect and suspiciousness) and job satisfaction (work itself
supervision co-workers pay promotion prospects and working conditions) Your
task is to determine if the individuals in the four college majors differ from one
another on the 12 measured variables
(a) What statistical technique(s) would you use to test for group differences
Explain Be specific about the procedures(s) that you would use
(b) What statistical estimate would you use to estimate the extent to which the
groups differ from one another Be specific
F4 The following statistical table published in a recent issue of Work amp Occupations
was taken from an article discussing variables influencing resistance and citizenship
behaviors in the workplace Resistance behaviors include playing dumb withholding
effort work avoidance subverting particular managers and sabotage Citizenship
behaviors include cooperation engaging in peer training use of insider knowledge to
facilitate production commitment to organizational goals giving extra effort freely
Both measures are global constructs aggregated to the interval level and
standardized
The table reports the results of a series of ordinary least squares regression equations
with standardized coefficients Explain the meaning of the statistics presented What
do these statistics tell us generally about the relationship between resistance
behaviors and anomie workplace control strategies and workplace characteristics
What do they tell us generally about the relationship between citizenship behavior
and anomie workplace control strategies and workplace characteristics Discuss the
relative advantagesdisadvantages of using standardized regression coefficients in the
data presentation The measurement levels for independent variables are as follows
Anomie Index -standardized interval level measure tapping multiple dimensions
The concept is used by the author to refer to norm violations that workers perceive
Work settings scoring high on the anomie index variable would be ones where
managements act capriciously and arbitrarily in dealing with workers and would not
tend sufficiently to production duties--ie planning providing supplies etc
Forms of Workplace Control -all are dichotomous (coded 1=present 0=absent)
with some overlap within cases Bilateral control refers to cases where management
allows subordinates input into decision making
Job Characteristics -skill and autonomy variables are interval level measures The
union presence variable is dichotomous (1=union 0=no union)
F5 Researchers collected data from a sample of 350 companies on the following
variables
size (measured as number of employees)
Business Strategy (a nominal variable with 2 response options low-cost provider or
differentiator)
HR Strategy (a nominal variable with 2 response categories High commitment or
low commitment)
Return on Equity (ROE)
Their proposition is that a firms HR strategy should match up with their business
strategy Specifically they believe that investing in high commitment workforce
practices is needed when a firm is trying to deploy a differentiation business strategy
Furthermore they believe that such a matching is especially important as firms grow
larger
Develop specific statistical hypotheses from these propositions using the variables
described above Then construct a regression model of the form Y = B1 X1 + B2 X2
+ that would test these hypotheses Explain what statistical test you would
examine to reach a conclusion about each hypothesis

I2 A study examined the effects of gender and pre-training motivation on the transfer of
training in terms of improved performance for 123 new industrial managers The

affected the statistical outcomes of the studies included in the literature review Meta-
analysis however allows one to statistically examine such effects Assume you are
conducting a meta-analysis of the relationship between leader behaviors and group
productivity Briefly describe the steps you would take in conducting a meta-

Step-wise regression
Non-linear regression
Moderated regression
M) General Linear Model
M1 The general linear model underlies most multivariate statistical methods Describe
and discuss the assumptions of the general linear model Multiple regression
ANOVA and principle components (factor) analysis are based on the general linear
model For each of those three statistical procedures describe and discuss the
following
a The type of data necessary for using the technique appropriately

assumptions usage and limitations
O3 How do exploratory and confirmatory factor analysis differ What are the
advantages and disadvantages of each
O4 Describe the differences between exploratory factor analysis (EFA) and
confirmatory factor analysis (CFA) When would you use one verses another
Are there ways to use EFA in a confirmatory way Can you use CFA in an
exploratory way Also describe the difference in principal components analysis
(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression
O6 The basic factor analysis model can be represented by the matrix algebraic
equation A B = C
(1) What do each of these matrices represent Be specific as to the type of
information in each matrix and its purpose
(2) For what purpose do researchers use factor analysis Explain In the process
provide a very brief description of a study for which factor analysis would be a
useful data analytic technique
O7 Factor analysis is an important statistical technique in organizational research
Describe factor analysis as an analytical tool including the following issues
a the reasons for using factor analysis
b the type of data necessary for using the technique appropriately
c the type of quantitative output that results from applying the technique
d how a researcher would use the output in his or her research
e how confirmatory factor analysis is different from exploratory
f the important issues and problems in using the technique
P) Structural Equation Models
P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of

P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and

confirmatory factor analysis (CFA) When would you use one verses another
Are there ways to use EFA in a confirmatory way Can you use CFA in an
exploratory way Also describe the difference in principal components analysis
(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression

provide a very brief description of a study for which factor analysis would be a
useful data analytic technique

P) Structural Equation Models
P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

parameter estimate bias in structural equation modeling Structural Equation

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)
Please comment on these restrictions versus access argument Which side do you
take
What are the strengths of SEM Give some examples
What are the weaknesses of SEM Give some examples

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by

I1 ANOVA Assume that you have conducted a laboratory experiment in which there
were 3 levels of Factor A (a1 a2 a3) and two levels of Factor B (b1 b2) Assume also
that there were 20 subjects in each cell
(a) Prepare a standard analysis of variance (ANOVA) table that is appropriate for this
design Make certain that you specify all effects and the appropriate degrees of
freedom for each effect If you use any abbreviations in your table make certain that
you specify their meaning
(b) Assume that an initial ANOVA analysis found no evidence of an A X B
interaction What if anything would you do with the sum of squares for the
interaction effect
I2 A study examined the effects of gender and pre-training motivation on the transfer of
training in terms of improved performance for 123 new industrial managers The
training was on supervisory skills and the dependent variable was based on the
appraisal of the supervisors performance before the training and three months after
the training The performance appraisal data were collected for research purposes
only and resulted in a total transfer score from 1 to 25 with 1 being low Pre-training
motivation was based on a 12 item Likert scale with an alpha of 86 Two groups
were identified for the pre-training motivation variable - the bottom 13 (low) and the
top 13 (high) Table 1 contains the ANOVA results and Table 2 contains the cell
means

(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide

types of techniques How does hypothesis testing differ in this context relative to

e how confirmatory factor analysis is different from exploratory
f the important issues and problems in using the technique
P) Structural Equation Models
P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)

that researchers do not carefully examine how particular research designs might have
affected the statistical outcomes of the studies included in the literature review Meta-
analysis however allows one to statistically examine such effects Assume you are
conducting a meta-analysis of the relationship between leader behaviors and group
productivity Briefly describe the steps you would take in conducting a meta-

meta-analysis What steps would you take in gathering and coding data to enhance
the credibility of your analysis
K) MTMM

any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How

performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find

confirmatory factor analysis (CFA) When would you use one verses another
Are there ways to use EFA in a confirmatory way Can you use CFA in an
exploratory way Also describe the difference in principal components analysis
(PCA) and EFA
O5 There has been a remarkable convergence of evidence in the personality
(individual differences) literature in the last ten years toward the Big Five
theory of personality structure So if a management researcher is interested in
the enduring traits of top managers job candidates boundary role spanners or
any set of individuals it is now requisite to measure one or more of the Big
Five characteristics Openness to Experience (O) Conscientiousness (C)
Extraversion (E) AgreeablenessConformity (A) and NeuroticismNegative
Affectivity (N) Unfortunately almost all of the well-established measures of
these personality dimensions are copyrighted and cost $1 or more per subject to
use in research Hence there is a clear need for someone to develop a public
domain set of measures of the Big Five
Suppose you were on a research team to develop that set of measures and youre
aiming for having 100 total items with 20 in each dimensional subscale Suppose
also that you collect data using these new items from 350 undergraduates who
also give your scale to their best friend so that you can have both self- and
social-reports of the undergraduates personalities (350 people being rated with
100 self-report items and another 100 social report items = 200 items total) How
would you use exploratory and confirmatory factor analysis (EFA and CFA) to
examine and help to validate your public domain measures Specifically
a -d What steps would you go through and what choices would you make in
performing an EFA on this data set In your answer make some justified guess
at the factor structure you expect to find
Armed with your EFA results how would you use (sketch out a plan without
getting into great detail regarding degrees of freedom and so on) CFA to provide
a more formal test of the fidelity of your measure In your answer distinguish
the important differences in purposes assumptions and mechanics of the two
types of techniques How does hypothesis testing differ in this context relative to
others such as regression
O6 The basic factor analysis model can be represented by the matrix algebraic
equation A B = C
(1) What do each of these matrices represent Be specific as to the type of
information in each matrix and its purpose
(2) For what purpose do researchers use factor analysis Explain In the process
provide a very brief description of a study for which factor analysis would be a
useful data analytic technique
O7 Factor analysis is an important statistical technique in organizational research
Describe factor analysis as an analytical tool including the following issues
a the reasons for using factor analysis
b the type of data necessary for using the technique appropriately
c the type of quantitative output that results from applying the technique
d how a researcher would use the output in his or her research
e how confirmatory factor analysis is different from exploratory
f the important issues and problems in using the technique
P) Structural Equation Models
P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels

P4 Some researchers argue that Structural Equation Modeling (SEM eg LISREL)
is a very powerful data analytic technique which has not been applied enough in
substantive research while others would argue that its benefits have been greatly
exaggerated and that it has been overapplied Consider these perspectives by
discussing the various strengths and weaknesses of SEM In your discussion you
should address among other things how SEM compares to other data analytic
techniques What do you think about the underapplicationoverapplication of
SEM
P5 Structural equation modeling has gone from an obscure and complicated
statistical tool to one that is commonly demanded by reviewers and used by
relative novices As SEM becomes more user friendly a number of statistical
experts have voiced concerns about the wisdom of making programs like LISREL
and EQS accessible to the masses (with simplified programming languages and
graphic user interfaces)

equation A B = C
(1) What do each of these matrices represent Be specific as to the type of
information in each matrix and its purpose
(2) For what purpose do researchers use factor analysis Explain In the process
provide a very brief description of a study for which factor analysis would be a
useful data analytic technique
O7 Factor analysis is an important statistical technique in organizational research
Describe factor analysis as an analytical tool including the following issues
a the reasons for using factor analysis
b the type of data necessary for using the technique appropriately
c the type of quantitative output that results from applying the technique
d how a researcher would use the output in his or her research
e how confirmatory factor analysis is different from exploratory
f the important issues and problems in using the technique
P) Structural Equation Models
P1 Structural equation modeling (SEM) has become one of the more popular data
analytic techniques in the social sciences Like any analytic technique it has its
advantages and disadvantages 1) Explain the advantage of SEM over regression-
based path analysis associated with measurement error 2) explain the notion of
maximum likelihood estimation broadly defined 3) define compare and
contrast any three of the fit indices offered by LISREL and 4) discuss
unmeasured variables problem ala James (JAP 1980) and how it affects
parameter estimation
P2 There now exist dozens of model fit for SEM Tanaka (in Bollen amp Long 1993
Testing structure Equation Models) offered six dimensions on which fit indices
vary The four dimensions with which you are concerned are Simplicity vs
Complexity Normed vs Nonnormed Absolute vs Relative and Sample size
independent vs Size dependent Your tasks are to explain these four distinctions
and to give examples of fit indices that represent each category (eg Normed fit
index and nonnormed fit index) explaining briefly why each index is
representative of the category
P3 An important consideration in structural equation modeling is whether manifest
variables should consist of individual items or item parcels (ie sums or averages
of individual items) For instance a construct measured with 10 items may be
specified by treating each item as a separate manifest variable or by averaging
TH
pairs of items thereby yielding five manifest variables The use of individual
items versus item parcels has generated considerable controversy (eg Bandalos
2002 Bandalos amp Finney 2001 Landis Beal amp Tesluk 2000 Marsh Hau
Balla amp Grayson 1998) Some researchers advocate the use of item parcels
whereas other research argue in favor of using individual items Discuss the
relative merits of using individual items and item parcels in structural equation
modeling Summarize your discussion by presenting guidelines that stipulate
when and under what conditions organizational researchers should use individual
items versus item parcels
