Comparison of Black and Nonminority Validities for the General Aptitude Test Battery. USES Test Research Report No. 51.
Synk, David J.; Swarthout, David
Meta-analytic research techniques were used to compare the General Aptitude Test Battery (GATB) validities of blacks and non-minorities. The sample consisted of 7,854 black and 15,769 non-minority subjects from 113 Specific Aptitude Test Battery (SATB) validation studies analyzed since 1972. The first approach was to compare average validities weighted by sample size. Eight of nine differences were significant and favored the non-minority sample. The largest difference was 0.05. A second approach use a chi-square method developed in 1979 by J. E. Hunter, F. L. Schmidt, and R. Hunter. Two aptitudes revealed differences significant at the 0.05 level. Cumulative chi-square analyses across all studies showed significant differences at the 0.05 level for four aptitudes. The last two analyses attempted to correct for sources of Type 1 error present in the primary analysis. One compared job family validities and found significant differences for two of five job families. The second corrected for range restriction and criterion unreliability and found significant differences in 10 of 24 critical ratios. The results tend to mirror those of other researchers. Differences, when found, were small and inconsistently favored non-minorities. Given the various forms of Type 1 error and the methods of data collection, there was little indication that validities differ more than would be expected due to chance. Five tables provide study data. Appendices provide tables of the sample members' job information and the distribution of statistics for blacks and non-minorities. (Author/SLD)
