The human resources (HR) director at a major telecommunications firm wants to determine the validity of a test for predicting future performance of sales staff. The company maintains records on the amount of sales dollars generated by each sales rep. This figure is to be used as a criterion of job success. The new test is administered to the current sales force (80 individuals). Test scores are then correlated with sales figures of the sales people. Test score and sales figures are gathered at approximately the same time. If an acceptable correlation exists, the test is shown to be valid and can be used for selection of future sales people. What type of validity does this process measure? A. Construct Validity B. Content Validity C. Predictive Validity D. Concurrent Validity
