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. Occur when the questions asked on a sample survey are confusing or leading

2. Perception of a correlation between variables where none exists.

null hypothesis
construct validity
14. Perception of relationship where none exists.
p value

empiricism
illusory correlation
15. Researchers takes subjects & conditions as they naturally occur - with little if any control over what happens. no random assignment so no cause and effect can be determined
confederates
mode
normal distribution

random sample
scatterplot
18. Procedure that ensures every person in a population has an equal chance of being chosen to participate

19. Form of validity in which a psychological measure is able to predict some future behavior or is meaningfully related to some other measure
hypothesis
interval data
null hypothesis
criterion validity
20. Condition of experiment that exposes participants to treatment - that is - to one version of the IV

correlation
scientific method
false consensus effect
21. When a specific word used in a question affects how respondents answer the question or the order of the questions
