Discriminant analysis of gross and fine motor proficiency data

Two classes of non-handicapped and two classes of handicapped children (n = 67), aged 5 to 12 years, took part in a study designed to determine whether a regular or specially designed physical education program suited their individual needs best. Initially receiving instruction with class peers each child was administered the 14-item short-form Bruininks-Oseretsky Test of Motor Proficiency. Discriminant analysis of the data indicated that two of the three functions were significant, together accounting for 93% of the variance. For each significant function fewer than half the test items contributed substantial discriminatory power. Over-all, 75% of the subjects were correctly classified but misclassifications occurred in each class; different placements seem appropriate for non-handicapped and handicapped children.
