+Welcome 9/23 AP PsychStarter: Get your BEST Experiment out Population: Complete set of cases from which
samples may be drawn
Operational Definition: a specification of how a researcher measures a research variable. This allows for replication – the repeating of an earlier study
Random Sample: Everyone in your population has an equal chance of being selected
Double Blind procedure both researcher and participant are ignorant about which participants have actually received a specific treatment (BEST)
Placebo effect: inert substance that is presumed to have medicinal benefits
+BEST Experiment Experimental condition: This allows up to exercise
maximum control over the factors we are interested in studying (BEST). The experimenter manipulates factors to produce a particular behavior
Control Condition; In order to provide a baseline against which they can evaluate the effects of (BEST) experimenter will use a control group
Random Assignment: Each individual in random sample has an equal chance of being assigned to either group.
Independent Variable: The variable being manipulated- BEST
Dependent Variable: The variable being measured-Cavities
+BEST Experiment
Only means by which cause and effect can be established
Allows for control of variables
Can be replicated
An experiment is not typical of real life situations
Behavior may be limited because of lab setting
Demand Characteristics: cues that convey to the participant the purpose of the experiment
Confounding variables-an extraneous variable whose presence affects the variables being studied so that the results you get do not reflect the actual relationship between the variables under investigation.
Benefits Limits
+American Psychological Association Ethics
1. Obtain informed consent
2. Protect from harm or discomfort
3. Participant confidentiality
4. Explain research to the participants after the study has been completed
+Statistical terms Mean – Average of #s. Most likely to effected by a
couple of outlier scores
Mode- # repeated most often
Median- The middle #
Range: the difference between the highest and lowest scores in distribution
Standard Deviation – arithmetic average of the distribution of scores - measure of the degree of variation amount a set of events
Correlation Coefficient: statistical measure most helpful for indicating strength of a relationship (+1 perfect positive, -1 perfect negative
+Some things to make sure your review
Definition of psychology
False consensus
Illusory correlation
