Detailed explanation-1: -How are reliability and validity assessed? Reliability can be estimated by comparing different versions of the same measurement. Validity is harder to assess, but it can be estimated by comparing the results to other relevant data or theory.
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: -Correlation coefficients A correlation coefficient ignores the units of two variables. It measures the relationship between two variables rather than the agreement between them, and is therefore commonly used to assess relative reliability or validity.
