What are item-criterion correlations? Describe one way in which developers use them?
What will be an ideal response?
• Some developers correlate item responses with a criterion measure such as a measure of job performance for pre-employment tests or a diagnostic measure for clinical tests. These are called item-criterion correlations.
• The item-criterion correlation can be used as a guide for determining whether the item contributes to prediction of the criterion. For instance, items that correlate strongly with the criterion would be helpful in predicting the criterion.
• One of the ways that item-criterion correlations are used is in the design of empirically based tests.
• Empirically based tests are designed so that test scores can be used to sort individuals into two or more categories based on their scores on the criterion measure.
• The decision to place an individual in a category is based solely on the quantitative relationship between the predictor (test score) and the criterion (possible categories).
• The Minnesota Multiphasic Personality Inventory, a widely used personality inventory, is an example of an empirically based test.
