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. Tendency to give socially approved answers to questions about oneself.

2. Condition of experiment that exposes participants to treatment - that is - to one version of the IV

13. Sample that fairly represents a population because each member has an equal chance of inclusion.
Hawthorne Effect
quasi-experiment
construct validity
random sample
14. 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.
