It is generally believed that there are significant correlations between the height and various motor abilities of man. But it is rarely practiced to utilize these correlations as concrete criteria for evaluating students' motor abilities demonstrated in physical education activity classes. The purposes of this study were to elucidate these correlations between heights and motor abilities in taking account of their sizes of stature for practical use. Two thousand four hundred and thirtysix male students from 11 universities and 3 technical high schools were tested and measured on their height, weight, 50 meter. run, 100 meter run, vertical jump, and handball throw. It was conducted between November, 1968 and February, 1969. Both calculated correlation coefficients(r) and regression coefficients(b) were significant between heights and 50 meter run (5% level), 100 meter run (5% level), vertical jump (1% level), and handball throw (1% level), respectively. In this report, some of the standardized rating tables for the evaluation of university students' motor abilities were presented, being based on the obtained regression lines and their standard deviations from regression(S_x). The formula used for drawing regression lines was Y = y + b (x - a). Regression values (Y) and their standard deviations were used as criteria to make five ranked scales, which were divided according to Y ±_x, Y±_x. When these scales were applied to actual evaluation, the grades of about 15 to 30% of the total students were changed from their previous grades based on only their motor abilities. Therefore, the present investigators recommend to use these evaluating method even for the university students when trying to grade them fairly, i. e., negating some hereditary factors such as the size of stature and putting emphasis on students' efforts in performing various motor activities.
