Prediction of Job Performance for Negro and White Medical Technicians. A Regression Analysis of Potential Test Bias: Predicting Job Knowledge Scores from an Aptitude Battery.
Campbell, Joel T.; And Others
An aptitude battery was validated against a Job Knowledge Test to determine if aptitude tests are culturally biased when used to predict occupational success. 287 white and 168 Negro Medical Technicians completed an eight test experimental aptitude battery and a Job Knowledge Test developed as a criterion measure of job performance. Linear regression analysis was used to detect the potential bias. All the aptitude tests were found to be culturally biased, but seven of them displayed bias in the direction opposite to that expected. For any predictor score on the seven tests, white technicians were likely to score better on the Job Knowledge Test than did Negroes with the same score. Consequently the bias was against the whites in that they performed better on the criterion for any given predictor score. To the investigators' knowledge there is no hypothesis or theory to explain the phenomenon of reverse unfairness which they have encountered. (RM)
