Intercorrelations of the Wechsler Intelligence Scale for Children—Revised, the Slosson Intelligence Test, and the National Educational Developmental Test

Abstract

For a primary middle-class Caucasian sample of 16 girls and 17 boys ( N = 33) enrolled in a secular private school in Clarksville, Tennessee Pearson, product-moment correlations were computed between the Slosson Intelligence Test (SIT) and the Wechsler Intelligence Scale for Children—Revised (WISC-R) Full Scale, Verbal, and Performance scores, and between National Educational Development Test (NEDT) scores and (a) WISC-R Full Scale and (b) SIT IQ scores. The coefficients obtained were, respectively, .79, .82, .50, .77, .77, all of which were significant beyond the .01 level.
