Quizplus · Accepted Answer

A retest estimate is used to assess the consistency of test scores over time. To use this method, the same test is administered to the same individuals at two different points in time, and their scores at time 2 are compared to their scores at time 1. This allows for an assessment of the reliability of the test over time, as well as an estimation of how much measurement error may be present in the scores.
