The effect of specialized industrial norms on the use of the Minnesota Rate of Manipulation Test as a selective instrument in employment procedure

Abstract

Results obtained from 468 male and 2007 female applicants at a large manufacturing company in the New York metropolitan area were used to establish new percentile norms on the Minnesota Rate of Manipulation Test. The applicants were 18-25 years old, with 75% not older than 20. Both new and original norms are presented and found to differ significantly from one another. On the placing test men and women differed significantly; hence, separate norms are presented for men and women. On the turning test the sex differences were not great enough to warrant separate norms. "The use of norms is valuable as a measuring rod for selection in industry but only in so far as the type of group on which the norms have been set and the conditions under which the test was standardized are known."
