Even if methodological and statistical differences across criterion-related validation studies are not controlled for statistically, it is still probable that validity can be generalized from one specific situation to another.

Question

Quizplus · Accepted Answer

Failure to control for methodological and statistical differences across validation studies can lead to a lack of generalizability of validity from one situation to another. Validity depends on the context and conditions under which a test is administered, and variations in these conditions can affect the accuracy of test scores in different settings. Thus, it is important to establish validity across a range of situations and testing conditions to ensure that a test is useful and reliable in different contexts.
