1. Define reliability: consistency of a measure
2. test-retest: Measuring the same individuals at two points in time and comparing results
good for behaviors that DON'T change -> remain constant
3. internal consistency: reliability using the responses at only one point in time
good for behaviors that DO change over time
4. interrater reliability: the correlation between the observations of different raters
Test of equivalence.
5. What is the Reliability and accuracy of the measures?: A measure can be highly reliable
but NOT accurate
6. Discuss ways to establish construct validity: the degree to which a test actually measures the
construct it's designed to measure
7. Face validity:: assessing whether a test of happiness genuinely measures levels of happiness
8. Content validity:: A scale for assessing anger management
9. Convergent validity:: A French vocabulary test would have high convergent validity if candidates who took
the test would get similar scores on different French vocabulary tests.
10. Discriminant validity:: the scores of two tests measuring security and loneliness should not be correlated.
(two Tests should not be related)
11. Criterion Validity -: the idea that the measure is related to a specific relevant outcome.
12. Predictive validity-: whether a test can accurately predict a particular future behavior.
13. Concurrent validity: is present when scores on a test correlate with an already validity measure given at
the same time (concurrently).
14. Describe the problem of reactivity of a measure of behavior and discuss ways
to minimize
Reactivity: - Reactivity of a measure of behavior is a change or alteration in behavior made due to an awareness
of being observed. The change could be positive or negative depending on the situation.
- Measure Is Reactive if Awareness of Being Measured Changes an Individual's Behavior
- Measures of Behavior Vary in Terms of Their Potential Reactivity
- In order to minimize reactivity you could use nonobtrusive or nonreactive measures that will not be
reactive. You could also wait until subjects being measured are so used to being recorded or observed that they don't
