Structured versus Unstructured
Observervational Studies (cont.)
Unstructured Observational Studies:
Observing events that are happening may also be a part of the plan as in many qualitative studies, the observer will record
almost everything that is observed.

Advantages of Observational Studies
The data obtained through observation of
events. It is easier to note the effects of
environmental influences on specificoutcomes.
It is easier to observe certain groups of individuals.

Disadvantages of Observational Studies
It is necessary for the observer to be
physically present. This method of collecting data is slow,
tedious and expensive.

Disadvantages of Observational Studies
(cont.)
Observer fatigue could easily set in, which
might bias the recorded data.
Observers have to be trained in what andhow to observe, and ways to avoid observer
bias.

Data Collection Through Mechanical
Observation
There are situations where machines can
provide data by recording the events of interest as they occur, without a researcherbeing physically present.

Multimethods of Data Collection
Because almost all data collection methods
have biases associated with them, colletingdata through multi-methods and frommultiple sources lends rigor to research.

Ethics and The Reseacher
Treating the information given by respondent.
Researchers should not misrepresent thenature of the study to subjects, especially in lab experiments.
Personal or seemingly intrusiveinformation should not be solicited.

Ethics and The Reseacher (cont.)
No one should be forced to respond to thesurvey.
Nonparticipant observers should be asnonintrusive as possible.
In lab studies, the subjects should be
debriefed with full disclosure of thereason.

Ethics Behaviors of Respondents
The subject, once having exercised the
choice to participate in a study, shouldcooperate fully in the task ahead.
The respondent also has an obligation tobe truthful and honest in the responses.
