Instructions:
Answer 50 questions in 15 minutes.
If you are not ready to take this test, you can
study here
.
Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.
This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Form of validity in which a psychological measure is able to predict some future behavior or is meaningfully related to some other measure
r
positive correlation
criterion validity
case study
2. Experimental results caused by expectations alone; any effect on behavior caused by the administration of an inert substance or condition - which is assumed to be an active agent.

ANOVA
mean
3. All cases in a group - from which samples may be drawn for a study

5. Graphed cluster of dots - each of which represents the values of two variables. The slope of the points suggests the direction of the relationship between the two variables.

overconfidence effect
experimental condition
median
13. Set of assumptions used to explain phenomena & offered for scientific study

theory
14. A type of reliability - where different versions of same instrument are used and scores are compared
scientific method
alternate form reliability
n
operational definition
15. The probability level which forms basis for deciding if results are statistically significant (not due to chance).
hindsight bias
p value
extraneous variables
positive correlation
16. Variable not relevant to what you are studying that has unplanned effect on DV. It may influence results - but all conditions are effected so it does not create bias.
mean
empiricism
test-retest reliability
extraneous variables
17. Sample that fairly represents a population because each member has an equal chance of inclusion.
double-blind procedure
random sample
nominal data
ANOVA
18. A research method that looks like an experiment BUT subjects are not randomly assigned to control and experimental groups (no cause and effect can be drawn)
quasi experiment
positive correlation
ratio data
random sample
19. The tendency for people to behave differently when they know they are being studied
cross-sectional research
Hawthorne Effect
overconfidence effect
correlational study
20. A test is divided into 2 halves and scores on the halves are compared to see if test is consistent within itself. Ex. compare odds & evens
wording effects
meta analysis
split half reliability
correlational study
21. Data exists in categories that are ordered but differences cannot be determined or they are meaningless. (Example: 1st - 2nd - 3rd)

median
24. We overestimate our accuracy and our changes of success and ability to predict and explain
