Multiple discriminant analysis of Minnesota Multiphasic Personality Inventory (MMPI) scores between high-IQ White, high-IQ Black, low-IQ White, and low-IQ Black subjects yielded two significant canonical variates. Results suggest that racial differences on the MMPI do not occur in all racial comparisons but are restricted to low-IQ groups. (Author)
