Indices of the discriminatory power of items, based on the differences in performances of groups, can be influenced by the degree of factorial mixture with respect to such groups. An illustrative example is presented, using hypothetical data. Items, normally rejected on the basis of such discriminatory tests, may be of value for predictive purposes. An empirical example of such a use is offered.
