Differential validity refers to a test's ability to have more validity for one group compared to another. This is different from known group validity, which refers to a test's ability to differentiate between two known groups, and single group validity, which refers to a test's ability to accurately measure a single group. Validity generalization refers to the extent to which a test's validity can be generalized across different populations or situations.
