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: -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-4: -Reliability refers to the consistency of a measure. 1 A test is considered reliable if we get the same result repeatedly. For example, if a test is designed to measure a trait (such as introversion), then each time the test is administered to a subject, the results should be approximately the same.

Detailed explanation-5: -Test-retest reliability has traditionally been defined by more lenient standards. Fleiss (1986) defined ICC values between 0.4 and 0.75 as good, and above 0.75 as excellent. Cicchetti (1994) defined 0.4 to 0.59 as fair, 0.60 to 0.74 as good, and above 0.75 as excellent.
