When assessing the reliability of a measure, one might be interested in knowing how scores on the measure at one time relate to scores on the same measure at another time. This refers to:

A. correlation coefficient.

B.test-retest reliability.

C. retest validity.

D. test utility.

Test-retest reliability is used when measuring the the consistency or relationship between the scores of two tests of the same variable, taken at different times.

It involves comparing the score on the first test taken earlier, with the score on a second test taken later.

The measure is considered to be reliable if there is no significant difference between the two test scores.
