PSY 250 EXAM 2 CSU STUDY GUIDE 2026
1. predictor variables: correlates with or predicts other items in the survey (chronic illness, weight)
2. outcome variables: what you are interested in studying
3. a likert scale: indicates the degree of agreement or disagreement to a statement
4. test-retest reliability: ditterent tests improves reliability of answers however seeing same items repeatedly
makes performance second time around open to carryover ettect
5. parallel-forms reliability: eliminates testing ettect. administering two versions of a test with questions that
probe the same constructs
6. split-half reliability: eliminates problem of changes in the variable over time. the test is split in two and the two
scores are compared to measure internal consistency reliability
7. internal consistency reliability: use multiple questions to measure the same thing, how well the items
agree
8. face validity: does the measure appear to measure the variable of interest?
9. content validity: does the measure include a representative sample of the behaviors that are relevant to the
variable
10. criterion validity: how strongly do the participants scores on your new measure correlate with their scores
on a ditterent previously established measure
11. concurrent validity: the degree to which scores in another measurement relate to other measurements
that have been established as valid
12. predictive validity: the ability of a test or measurement to predict a future outcome
13. construct validity: does the pattern of results obtained from a test agree with what is theorized about the
construct being measured
14. convergent validity: the extent to which your test or measure accurately measures what its supposed to
15. discriminant validity: is your measure unrelated to constructs that it should be distinct from? such as IQ
and desirability
1/7
, 16. behaviors must be: operationally defined
17. interrater reliability: the degree to which ditterent observers agree on their observations
18. percent agreement: for each behavior do rater 1 and 2 agree?
%=... should be greater than 70%
19. Cohen's Kappa: needs to be >.70
20. Pearson product-moment correlation: compute correlation between R1 and R2
21. what can cortisol be used to measure: medical measure to identify diseases that use too little or
too much
2/7
