运用聚类方法指导体育教学

Guiding physical education with clustering methods

运用R型聚类方法从与体育教学研究相关的常用人体形态指标中筛选典型指标,用以指导体育教学。通过"物以类聚"运用微机进行统计运算,其归类结果如下:第1类:身高、坐高、肩宽、骨盆宽;第2类:体重、胸围;第3类:50m跑、立定跳远、1000m跑;第4类:引体向上,本例以相关系数R=0 714为界,从各类中筛选的典型指标为:身高、体重、立定跳远、引体向上。

about body morphologic items in P.E. with Rclustering method. Statistic computing was done with the computer and the results were categorized as follows. The fist class included height,set length,shoulder width and pelvis width. The second class included weight and circumference. The third class was consisted of 50?m run,standing long jump and 1 000?m run. And the last class was chinup. Being limited by relative coefficient R=0714,typical indexes selected were height,weight,standing long jump and chinup.
