The term predictive bias may be used when evidence is found that differences exist in the patterns of associations between test scores and other variables for different groups, bringing with it concerns about bias in the inferences drawn from the use of test scores. Differential prediction is examined using regression analysis. One approach examines slope and intercept differences between two targeted group (e.g., African American examinees and Caucasian examinees), while another examines systematic deviations from a common regression line for any number of groups of interest. Both approaches provide valuable information when examining differential prediction Correlation coefficients provide inadequate evidence for or against a differential prediction hypothesis if groups are found to have unequal means and variances on the test and the criterion.
