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. Statement that describes how to measure a particular variable or define a particular term specifically in a study
psychological test
wording effects
experiment
operational definition
2. Extent to which scores suggest that a test is actually measuring an ABSTRACT theoretical idea (such as anxiety - personality - introversion - etc.).
type one error
construct validity
face validity
correlation
3. Correlation where as one variable increases - the other also increases - or as one decreases so does the other. Both variables move in same direction.

7. Variable not relevant to what you are studying that has unplanned effect on DV. It may influence results - but all conditions are effected so it does not create bias.

operational definition
9. Extent to which the findings from one group (or sample) can be generalized or applied to other groups (or population

13. Research project designed to discover degree to which two variables are related to each other

14. Extent to which a test measures or predicts what it is supposed to - test accuracy
validity
negative correlation
content validity
meta analysis
15. Sample that fairly represents a population because each member has an equal chance of inclusion.
p value
negative correlation
random sample
positive (right) skew
16. Effects of being born and raised in a particular time or situation where all other members of your group has similar experiences makes your group unique from others
cohort effects
quasi-experiment
negative (left) skew
meta analysis
17. 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
social desirability bias
quasi-experiment

test-retest reliability
Hawthorne Effect
negative correlation
experimental condition
22. The probability level which forms basis for deciding if results are statistically significant (not due to chance).
