基于乒乓球比赛技战术的统计推断方法研究

Research on Statistical Inference Method Based on Technique and Tactics of Table Tennis Match

对乒乓球技战术分析方面的统计学概念进行了梳理;在分析近5年来高校运动训练学乒乓球方向学位论文中统计推断方法应用严重匮乏的基础上,根据多年跟随国家乒乓球队科研技术工作的实际需要,具体提出适用的统计推断方法。期望能够对提高目前此方向研究生的学位论文的科学性有一定的帮助和启示。研究结果:对于两名运动员的关于率的分析,运用独立样本列联表资料的2检验;多名运动员则用多个独立样本R×C列联表资料的2检验;对于两名运动员之间的技术质量评定,采用运用秩和检验中Mann-Whitney U检验;多名运动员则采用运用秩和检验Kruskal-Wallis H检验。乒乓球的技战术分析表格多为列联表的形式,属于汇总数据,在进行检验之前需要加权处理。多名运动员之间的比较,如果有显著性差异,并不代表两两之间有差异,需要进一步统计分析。

The statistical concepts of technical and tactical analysis of table tennis are summarized.Based on the analysis of the severe shortage of statistical methods in the academic dissertations on table tennis in colleges in the past five years,this paper puts forward some applicable statistical methods.It is expected to be helpful and enlightening to improve the scientificity of the dissertation of graduate students in this field.Results:for the analysis of the rate of two players,the chi-square test was used to analyze the contingency table data of two independent samples.More than two players use a number of independent samples R×C contingency table data chi-square test.the Mann-Whitney U test was used when evaluate two players.The Kruskal-Wallis H test was used for many players.The data in tables of Table Tennis technique and tactics analysis are mainly in the form of contingency table,which belong to the summary data.Weighting is required before testing.If there is a significant difference in the comparison between multiple athletes,it does not mean there is a difference between two athletes,and further statistical analysis is needed.
