The Effect of Geographic Area on General Aptitude Test Battery Validity and Test Scores. USES Test Research Report No. 48.
Swarthout, David; And Others
Meta-analysis techniques were used to determine whether or not there are differences in General Aptitude Test Battery (GATB) validity and test scores between samples from the Northern, Southern, and Western United States census areas. The sample consisted of 26,111 subjects from 122 validation studies of the Specific Aptitude Test Battery (SATB). Four different methods were used to analyze the differences in validities: (1) comparison of average validities, weighted by sample size; (2) comparison of average differences in validities, weighted by sample size, between geographic areas; (3) comparison of job-family validities; and (4) chi-square (Hunter, Schmidt, and Hunter). The overall conclusion was that there were no meaningful differences in GATB validity between geographic areas. Analysis of mean score differences indicated mean geographic area differences on all nine GATB aptitudes: general learning ability; verbal, numerical, and spatial aptitude; form and clerical perception; motor coordination; and finger and manual dexterity. The Western United States scored highest, with South lowest, and North in between. These differences were not attributed to racial status, since the same pattern was found for Blacks and nonminorities. (Author/GDC)
