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.

11. Rejecting null hypothesis when it is actually true - a false positive

controls
14. Statement that describes how to measure a particular variable or define a particular term specifically in a study
random assignment
operational definition
alternate form reliability
percentile rank
15. Measures whether a test looks like it tests what it is supposed to test as determined by a quick look or evaluation by a non expert
experimenter bias
type two error
alternate form reliability
face validity
16. 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)
mode
quasi experiment
construct validity
percentile rank
17. Tendency to give socially approved answers to questions about oneself.
p value
negative correlation

18. Research method in which investigator manipulates one or more factors (IV) to observe effect on some behavior or mental process (DV)
experiment
validity
operational definition
false consensus effect
19. Factors in an experiment that are unchanged for both the control group and the experimental group

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.
dependent variable
positive correlation
null hypothesis
test-retest reliability
21. Perception of relationship where none exists.
quasi-experiment
scientific method
illusory correlation
validity
22. Degree to which test is representative of total domain its supposed to cover.
mode
content validity
positive correlation
ANOVA
23. Graphed cluster of dots - each of which represents the values of two variables. The slope of the points suggests the direction of the relationship between the two variables.
illusory correlation
experiment
scatterplot
cohort effects
24. Research project designed to discover degree to which two variables are related to each other

scientific method
29. Bell-shaped curve that results when values of a trait in a population are plotted against their frequency
