Detailed explanation-1: -Test-retest reliability measures the consistency of results when you repeat the same test on the same sample at a different point in time. You use it when you are measuring something that you expect to stay constant in your sample.

Detailed explanation-2: -Test-retest reliability is a measure of reliability obtained by administering the same test twice over a period of time to a group of individuals. The scores from Time 1 and Time 2 can then be correlated in order to evaluate the test for stability over time.

Detailed explanation-3: -Having good test re-test reliability signifies the internal validity of a test and ensures that the measurements obtained in one sitting are both representative and stable over time.

Detailed explanation-4: -This correlation is known as the test-retest-reliability coefficient, or the coefficient of stability. The closer each respondent’s scores are on T1 and T2, the more reliable the test measure (and the higher the coefficient of stability will be).

Detailed explanation-5: -Description. Test-retest reliability measures the stability of the scores of a stable construct obtained from the same person on two or more separate occasions. Reliability concerns the degree to which scores can be distinguished from each other, despite measurement error.
