Ream (7) defines motility as the fundamental capacity for speed in a simple repeated movement. As a measure of motility the tapping test has several advantages. The test is simple, objective and easily given and quickly learned. It has the advantage of motivating the observer to do his best. In a review of earlier studies, Wells (10) concludes that the performance of boys is faster than girls and that sex differences increase with age. He predicts a consistent superiority of men over women in speed of movement as so measured. These two psychometric tests are assumed to be of interest to those in certain fields of skill such as driver education and selection. The strength of grip test being an indication of endurance and the motility test a measure of general activity and facility in certain types of performance. The purpose of this study is to determine age and sex differences in both the motility and strength tests under standard conditions. Since age and sex differences in the two tests have been reported in the literature without statistical evaluation the following null hypotheses were set up for experimental evaluation. 1. There is no significant differences in the performance between men and women on motility or strength. 2. There is no significant difference in performance among age groups used on motility or strength.
