Valid instruments are able to detect true differences among the people or objects being measured. Validity refers to the accuracy and truthfulness of the data collected through the sources and instruments. Criteria for validity may include the reliability, generalization power, and measure of relevance. The validity of data collected from either national or local samples cannot be generalized unless the data closely matches the survey criteria. Similarly, criterion-related validity is a concern not only for employee selection purposes but also for other studies, as it emphasizes the correlation between the measure and the outcome.
