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.

14. Condition of experiment that contrasts with experimental condition and serves as a comparison for evaluating the effect of the treatment.
control condition
illusory correlation
placebo effect
operational definition
15. 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.

extraneous variables
16. 'Fake subjects' that look & behave like real subjects in study.

17. Measures whether a test looks like it tests what it is supposed to test as determined by a quick look or evaluation by a non expert

experiment
random assignment
22. Association between increases in one variable and decreases in another
criterion validity
