Question

Quizplus · Accepted Answer

Discriminant validity refers to the ability of a measure to distinguish between concepts that are supposed to be different. In other words, it should not be highly correlated with measures of other constructs that are not related. Therefore, the correct answer is B, as it states that the results of a measure with discriminant validity should not correspond as highly with measures of other constructs as they do with other measures of the same construct.
