Answer to Question 1

ANS: A

Feedback
A Instrument homogeneity is established with split-half reliability.
B Test-retest reliability establishes instrument stability.
C Interrater reliability is not a homogeneity measure.
D Alternate form or parallel form reliability is not a test of homogeneity.

Answer to Question 2

ANS: B

Feedback
A Open-ended questions elicit textual data that are content analyzed (qualitative analysis).
B The KR-20 coefficient provides estimates of homogeneity used for instruments that have a dichotomous response format.
C Cronbach's alpha coefficient provides estimates of homogeneity when instruments are scaled with ordinal responses.
D The KR-20 coefficient does not apply to this answer.
