Question

Quizplus · Accepted Answer

One way to assess reliability is to calculate the correlation coefficient of the scores of the measure. This coefficient indicates the degree of association between two sets of scores in which the first set is obtained from the measure at one time and the second set is obtained from the measure at a later time. A high correlation coefficient suggests that the measure is reliable.
