Question

Quizplus · Accepted Answer

Test-retest reliability refers to the consistency of results across time. The best way to measure this is to have the same respondents complete the survey on two different occasions and compare their responses. Therefore, option C is the most useful technique for measuring test-retest reliability. Option A (Cronbach's alpha) is a measure of internal consistency reliability, which is not the same as test-retest reliability. Option B (using different wordings) is a technique for assessing construct validity, not test-retest reliability. Option D (organized review) is a technique for ensuring content validity, not test-retest reliability.
