An Analysis of Subtest Scatter on the Tests of Cognitive Ability from the Woodcock-Johnson Psycho-Educational Battery.
Marston, Doug
An analysis of scatter among the Tests of Cognitive Ability for the Woodcock-Johnson Psycho-Educational Battery was conducted on scores of 3,566 grade 1 through 12 students from the standardization sample. Large mean high subtest-low subtest differences were noted for each grade level and compared to Wechsler Intelligence Scale for Children-Revised scaled score ranges. Frequency distributions for high-low differences are presented as well as the mean differences between all pairwise combinations for the 12 subtests. The practice of examining scatter on the Tests of Cognitive Ability is discouraged. (Author)
