A Method for Displaying Incremental Validity with Expectancy Charts

Providing assessment validity information to decision makers in a clear and useful format is an ongoing challenge for the educational and psychological measurement community. We identify issues with a previous approach to a graphical presentation, noting that it is mislabeled as presenting incremental validity, when in fact it displays the effects of using predictors in a multiple hurdle fashion. We offer a straightforward technique for displaying incremental validity among predictors in reference to a criterion measure.
