Statistically inferred vs. Empirically observed VIQ‐PIQ differences in the WAIS‐R

A discussion on the distinction between statistically significant Verbal‐Performance IQ discrepancies and the frequencies with which such differences occur in the WAIS‐R standardization sample is presented. An example is provided to aid in the determination of Wechsler Verbal‐Performance IQ frequency data, and comparisons are made between statistically derived and empirically observed WAIS‐R Verbal‐Performance IQ frequencies. Implications for placing additional emphasis upon evaluating Verbal versus Performance IQ frequencies are delineated.
