Passage

The Wechsler Adult Intelligence Scale (WAIS) was administered to a sample of 300 subjects. The intercorrelations among all the subscales were obtained. Unities were retained in the diagonal spaces of the correlation matrix and it was factor analyzed. Cattell’s scree indicated two-factor solution. The two factors were subject to varimax rotation. The two rotated factors were named as Verbal Intelligence and Performance Intelligence. The two factors, together, explained 62 percent of variance. (December)
