Quizplus · Accepted Answer

Squaring the validity coefficient between a test and a criterion will tell us about the amount of shared variance, which is the proportion of variance in one variable that can be accounted for by another variable. This reflects the extent to which a test measures what it is intended to measure and is a key indicator of validity. Reliability refers to the consistency of test scores, and homogeneity refers to the extent to which items on a test are related to each other.
