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.

13. Research method in which investigator manipulates one or more factors (IV) to observe effect on some behavior or mental process (DV)

single-blind procedure
inter-rater reliability
interval data
17. Association between increases in one variable and decreases in another

overconfidence effect
negative correlation
18. Subset of a population in which every element in the population has an equal chance of being selected
p<.05

random sample
overconfidence effect
19. Results of experiment are SIGNIFICANT - they are not likely caused by chance
face validity
confounding of variables
p<.05
Hawthorne Effect
20. Relationship between variables in which as one variable increases - the other also increases - OR as one decreases so does the other. Both variables move in the same direction.

26. Any selection method that results in subset of the population (sample) that is not representative - and/or not random
stratified sample
