Answer: C - Criterion validity is a measure of how well one personality test provides results that correlate with results from a similar personality test.
Key Takeaway: In psychometrics or psychological testing, criterion validity is a measure of how well the variables of one test measure the same things as the variables of a similar test. If Jason’s second personality test results are very different from the first test, it does not have sufficient criterion validity. In other words, the second test doesn’t measure the same variables as the first test.
