@ the total range of scores of the group tested, from the lowest to the highest can be divided into five equal parts, to secure the range of the five sections. The first method allows a sectioning on the basis of the average ebility of the group; the second per* mits a naturel skewing of the curve to fit the peculitr distribu+ tion of the groups The middle groun, in large and normal classes, will always be the largest. This test has been given to 1,500 pupils of both soxes and ages ranging from 11 to 38 years. Physicsl size did not appreciably af« fect the functioning of the tests That is, a child of twelve years had no more difficulty in executing the exercises than did the college freshman. Tho curves of distribution of ability of both extreme age groups have the same charecteristics. However, the correlation bo tweon intelligences scores and the physical test scores is markedly differont for the two groups. For thee on college students, a correla tion of e49 wes found, while for junior high pupils, it was only wlde We cannot account for this at the prosent timo, except that it is likely a manifestation of maturatione This test for sectioning mist not be considered the last word in moasuroment of physical differences, but with intelligent use it is extromely valuable, especially in sectioning large clesses in _ physical cducations It is hoped that this presentation of tho test will bo usoful to teachersy and that it will stimulate further re- search in tho matter of differences in physical skill. As the test stands now, we can say of it thet: le Within broed limits, it measures native physical skill. 2s With matured groups its results have a relatively high core+ relation (49) with the results of intelligence tests. 3, It makes easy and valid the sectioning of classes into homo geneous groupse
