What is the likely effect of criterion bias on the predictor-criterion relationship in a validation study?
A)It lowers the range of scores on the criteria measures, which mathematically lowers the magnitude of the validity coefficient.
B)It increases the range of scores on the criteria measures which mathematically balances out, having no effect on the validity coefficient.
C)It both increases and decreases the range of scores on the criteria measures which mathematically balances out, having no effect on the validity coefficient.
D)It increases the range of scores on the criteria measures, which mathematically lowers the effect of the validity coefficient.

Criterion bias can result in a restricted range of scores on the criteria measures, meaning that there is less variety in the scores that are being used to establish the predictor-criterion relationship. This reduction in range ultimately results in a lower validity coefficient, as it reduces the ability of the predictor variable to accurately predict performance on the criterion variable.
