CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -Types of Reliability. 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-2: -Test-retest reliability is a statistical technique used to estimate components of measurement error by repeating the measurement process on the same subjects, under conditions as similar as possible, and comparing the observations.

Detailed explanation-3: -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.

Detailed explanation-4: -If the p-value is LESS THAN . 05, and the Pearson correlation coefficient is above 0.7, then researchers have evidence of test-retest reliability. If the p-value is MORE THAN . 05, or the Pearson correlation coefficient is below 0.7, then researchers do not have evidence of test-retest reliability.
