试析运动技术分析中统计学的应用误区

A general study on the application errors of statistics in the sport technical analysis

结合运动技术分析的特点与实例 ,分析了统计学应用的误区 ,包括 :①没有预先确定显著性水平 ;②样本含量的确定缺乏科学依据 ;③没有判断总体的概率分布情况 ;④没有正确理解显著性差异的概念 ;⑤没有正确区分单、双侧检验 ;⑥缺乏与有关学科的结合分析。

Combining the characteristics and instances of technical analysis,this paper analyzes the statistics application errors which include not defining the significance level in advance. And the certainty of the samples lack scien-tific basis. There is no total probability distribution situation. There's no understanding of the concept of significance discrepancy and no distinction between single and double testing value.There's also a lack in the combination analysis with relevant subjects.
