从类平均数、变异系数和权重看我国男子十项全能的差距

Analysis on Chinese Men's Decathlon Gap from the Class Averages,Coefficients of Variation and Weights

从观察到的男子十项全能不等的单项评分平均数现象出发,运用一致性的问题导向统计方法,揭示了在《评分表》原则、个体能力和项目内在逻辑制约下,运动员在训练、比赛中对10个项目选择性强化与"放弃"。三维变量及其多重组合,即平均数体现的单项水平、变异系数体现技术的稳定性和总评分回归方程中系数体现的权重,蕴含了不同的成绩与类别。

From the unequal scoring average phenomena observed by men＇s decathlon,armed with the consistency problem orienting statistical methods,this paper revealed that under the principle of the decathlon scoring tables,the individual capacity and the internal logical of the projects,athletes selectively surrendered and strengthened projects in training and racing.The three dimensional variables within its combinations including the scoring averages reflecting its single project level,the coefficients of variation showing its technical stability,and coefficients of the total regression equation displaying the weights,contained the different scores and its category.
