For example, suppose we are judging the performance of a group of quality control
inspectors on a work sample task (a device with l0 known defects). We set our criterion cutoff at
eight-that is, the identification of fewer than eight defects constitutes unsatisfactory performance.
The number of "successful" inspectors may increase markedly if the criterion cutoff is
lowered to five defects. Our conclusions regarding overall inspector proficiency are likely to
change as well. In sum, if we know the rules governing our criterion measures, this alone should
give us more insight into the operation of our predictor measures.
