In psychology, discriminant validity tests whether concepts or measurements that are not supposed to be related are actually unrelated.. Campbell and Fiske (1959) introduced the concept of discriminant validity within their discussion on evaluating test validity.They stressed the importance of using both discriminant and convergent validation techniques when assessing new tests. Another common misconception is that reliability is equivalent to validity. endobj validity; thus contributing to the overall construct validity. This can be illustrated using a simple data set of actual data collected from a class of graduate students enrolled in a Winter Quarter, 2003, research design course.
