B)test-retest reliability
C)intrarater reliability
D)criterion validity

Question

Quizplus · Accepted Answer

The measure of consistency described in the question is test-retest reliability. The correlation between the two testings is the correlation coefficient used to measure this reliability. Therefore, the best choice is B. The other options (A, C, and D) describe different concepts related to reliability or validity, but do not address the specific measure of consistency described in the question.
