Assessing the significance of differences between subtests on the wechsler adult intelligence scale-revised

Considered methods of evaluating the pattern of subtest scores on the Wechsler Adult Intelligence Scale‐Revised. The rationale and method for calculating the size of a significant difference between a subtest and the mean of the subtests scores for an individual are described. The score differential necessary at three probability levels for a reliable difference between the subtest mean and any one subtest, corrected for the number of a‐posteriori comparisons made, are presented.
