Document Summary
Importance of predictors: selection is all about prediction - forecasting who is likely to succeed in jobs based on available data. If we knew who was going to be a good performer, we wouldn"t need predictors. In effect, predictors forecast criteria since we don"t have criterion data. Classification of tests: test systematic procedure for observing behavior and describing it with the aid of numerical scales, tests = predictors = assessments, types of tests, speed vs. power. Individual (iq) vs. group: paper-and-pencil (can be online) vs. Performance: p-and-p tests most typical kind of test where individuals are asked to respond to a series of items in a test booklet, most cognitive ability tests (gres). Act, lsat, mcat: performance tests require the manipulation of an object or piece of equipment, flight simulations for pilot training. Summary of reliability types and validity approaches: reliability, test-retest: stability of test over time, parallel forms: equivalence of two tests forms.
