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. Giving participants in a research study a complete explanation of the study after the study is completed needed for deception

r
inter-rater reliability
13. Condition of experiment that contrasts with experimental condition and serves as a comparison for evaluating the effect of the treatment.
mean

14. In-depth - intensive investigation of individual or small group of people which involves interviews and personal interpretations by researcher. It may also be supplemented with psychological or medical tests

replication
15. Experimental procedure in which both research participants and research staff are ignorant about whether the research participants have received the treatment or a placebo.

reliability
median
double-blind procedure
16. Research method in which investigator manipulates one or more factors (IV) to observe effect on some behavior or mental process (DV)
double-blind procedure
debriefing
nominal data
experiment
17. 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)
mean
correlation
quasi experiment
p value
18. Tendency to give socially approved answers to questions about oneself.
quasi experiment

20. Research in which the same people are re-studied and re-tested over a long period
content validity
type two error
longitudinal research
stratified sample
21. 'Fake subjects' that look & behave like real subjects in study.
median

normal distribution
25. Any selection method that results in subset of the population (sample) that is not representative - and/or not random
Hawthorne Effect
random sample
