  1. Effect of Selection Ratio on Predictor Utility sr =.95 sr =.50 sr =.10 r =.40 Criterion Performance Reject Accept Selection Cutoff Score Predictor Score

  2. Effect of Predictor Validityon Predictor Utility sr =.50 r =.40 r =.80 r =.00 Criterion Performance Selection Cutoff Score Predictor Score

  3. Effect of Base Rate on Predictor Utility r =.40 br =.10 Criterion Performance br =.90 Predictor Score

  4. Selection Decisions sr = .50 sr = .75 True Positives r =1.00 r =.60 Successful Performance False Negatives A D br = .50 Criterion Performance C True Negatives False Positives B Unsuccessful Performance Reject Accept Predictor Score

  5. Selection Strategies • 3 Basic Strategies • Multiple Regression • Assumes relationships between predictors and criterion are linear • Assumes having a lot of one attribute compensates for having little of another • Multiple Cutoff • Applicants must achieve a set, minimum score on all predictors • Multiple Hurdle • Applicants must achieve satisfactory scores on a number of predictors that are administered over time.
