Suppose that the University Counseling Center has a measure of test anxiety in college students (called the TA test) that produces a score between 0 and 100. Suppose that you have developed a new test that you believe measures a different variable that you are calling “exam-performance inadequacy” (called the EPI test) that produces a score between 0 and 20. How would you demonstrate discriminant validity for the two tests to provide evidence that they are measuring different variables?
