PSY220 EXAM 2 CSULB STUDY GUIDE
Questions with 100% Correct Answers
Define reliability Correct Answer: consistency of a measure
test-retest Correct Answer: Measuring the same individuals at two points in time
and comparing results
good for behaviors that DON'T change -> remain constant
internal consistency Correct Answer: reliability using the responses at only one
point in time
good for behaviors that DO change over time
interrater reliability Correct Answer: the correlation between the observations of
different raters
Test of equivalence.
What is the Reliability and accuracy of the measures? Correct Answer: A
measure can be highly reliable but NOT accurate
Discuss ways to establish construct validity Correct Answer: the degree to which
a test actually measures the construct it's designed to measure
Face validity: Correct Answer: assessing whether a test of happiness genuinely
measures levels of happiness
Content validity: Correct Answer: A scale for assessing anger management
, Convergent validity: Correct Answer: A French vocabulary test would have high
convergent validity if candidates who took the test would get similar scores on
different French vocabulary tests.
Discriminant validity: Correct Answer: the scores of two tests measuring security
and loneliness should not be correlated. (two Tests should not be related)
Criterion Validity - Correct Answer: the idea that the measure is related to a
specific relevant outcome.
Predictive validity- Correct Answer: whether a test can accurately predict a
particular future behavior.
Concurrent validity Correct Answer: is present when scores on a test correlate
with an already validity measure given at the same time (concurrently).
Describe the problem of reactivity of a measure of behavior and discuss ways to
minimize
Reactivity Correct Answer: - 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
