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.

mean
wording effects
16. Condition of experiment that contrasts with experimental condition and serves as a comparison for evaluating the effect of the treatment.
control condition
negative correlation
experimenter bias
standard deviation
17. Not rejecting null hypothesis when in fact we should have rejected it - a false negative
cohort effects

type two error
empiricism
18. Sample drawn in such a way that known subgroups within a population are represented in proportion to their numbers in general population
stratified sample
overconfidence effect

19. Method by which participants are misinformed or misled about study's methods and purposes - must be told truth about this in debriefing
correlation coefficient
debriefing
random selection

20. Correlation where as one variable increases - the other also increases - or as one decreases so does the other. Both variables move in same direction.

meta analysis
ordinal data
22. Skewed distribution where data has many more scores toward the lower end of the distribution
