Document Summary
Industrial/organizational psychology (i/o) emphasis on psychological testing. Wore perfume and were overly friendly- they did not get the job. One or the other they did get it. If the test is a two choice test, there is often a cut off rate (above yes below no etc. ) The score marking the point for a decision is the cutting score. You can test if the test has put people into the right category- if it is for a job then simply monitor there job performance. Hit rate: the percentage of cases in which a test accurately predicts success of failure. Base rate: proportion of people expected to succeed on a criterion if they are chosen at random. The hit rate must tell us how much information a test contributes to the prediction of success beyond what we know just by examining the proportion of people who succeed.
