An evaluation of the Ferguson form boards and the derivation of new age and grade norms. Part 2. Presentation of norms and discussion

Abstract

Norms (25 percentile, median, and 75 percentile) for a group of 582 subjects are presented for the Ferguson form boards. Norms are given for both score and time for ages 6-15 and grades 2-8. While norms are given separately for the sexes, these are considered tentative because of the number of cases. The group upon which the test was standardized is shown to be an average urban school group. Boys are consistently superior to girls as judged by both time and score. The ratios of correlation between performances on the Ferguson form boards and Kuhlmann-Anderson tests indicate that the Ferguson boards measure the same type of behavior as verbal tests of intelligence to a greater extent than many other performance tests.
