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. Effects of being born and raised in a particular time or situation where all other members of your group has similar experiences makes your group unique from others

random sample
16. Condition of experiment that contrasts with experimental condition and serves as a comparison for evaluating the effect of the treatment.
