回归分析在短跑教学中的应用

针对教学中学生１００ｍ跑的具体情况，采用逐步回归分析方法建立了回归方程；在此基础上，分别以各相关因素、１００ｍ跑成绩作为因变量与自变量建立了多项式回归方程，并依据正态分布理论制定了各因素平衡发展的标准。上述方法在指导短跑教学中取得了较好的效果。

Application of Regression Analysis to Dash Teaching

In the light of the concrete conditions of teaching students'100-meter dash,a regression equation is established by using progressive regression analy-sis.The polynomial regression equations are derived from the above regression e-quation with the interrelated factor and the time of 100-meter dash taken as de-pendent and independent vaiables respectively.Criteria for equilibrium develop-ment of the factors are laid down according to the theory of normal distribution.Satisfactory result is achieved by using the above methods to quide dash teach-ing.
