EPPP TEST CONSTRUCTION QUESTIONS WITH COMPLETE SOLUTIONS

EPPP TEST CONSTRUCTION QUESTIONS WITH COMPLETE SOLUTIONS content validity - Answer-the extent to which the test items adequately & representatively sample the content area to be measured face validity - Answer-the test appears to the test takers, the personnel administering the test, & untrained observers to be valid. increases motivation to complete test, cooperation with test process criterion related validity - Answer-useful for predicting a person's behavior in a specific situations. scores on predictor test are correlated with an outside criterion, such as job performance, school achievement, or scores on another test validation - Answer-the procedures used to determine how valid a predictor is concurrent validation - Answer-the predictor & criterion data are collected at/about the same time. if a test is useful for predicting a given current behavior it has concurrent validity predictive validity - Answer-scores on the predictor are collected 1st then the criterion data are collected (future) formula for standard error of measurement - Answer-SEmeans = SD*(the square root of 1-r [reliability coefficient]) factors affecting the validity coefficient - Answer-1) restricted range of scores--more diverse the group (scores) the higher the validity coefficient. 2) both the predictor & the criterion must be reliable, however reliability does not guarantee validity 3) criterion-related validity may vary among subgroups within a population. 4) cross-validation: after 1 validation it is validated again with a different sample 5) criterion contamination: when the predictor scores influence any individual's criterion status
