Question

Quizplus · Accepted Answer

Test-retest reliability refers to the consistency of scores on a measure over time. Administering the same measure at two different times to the same people and computing the correlation between the two sets of scores is the best method to assess test-retest reliability, as it directly evaluates the consistency of scores for the same individuals. Option A would assess inter-rater reliability, while option C would assess convergent validity, and option D would assess inter-rater reliability for the same individuals.
