体育科研中多元总体均值推断的效果检测

Analysis of the Effects of Multi-population Mean Test in P. E. Scientific Research

针对目前体育科研中多元总体均值检验方法在应用中存在的问题进行分析,揭示问题的根源是对统计总体不明确,将多元总体拆成一元总体进行分析,导致统计方法脱离于研究总体。研究表明,对于多元总体采用一元统计检验的结果不可靠,建议对于多元总体均值向量的差异检验应当采用Hotelling T2检验方法。

By analyzing current problems in the application of population mean test in P. E. scientific research, the author reveals that the origin of the problems is the unclearness of the population, in which the multi-population is taken apart into mono-population. As a result, the statistics methods stray away from the population in research. The author points out that the result would not be reliable if you take mono-statistical test in multi-population. He suggests that the Hotelling T2 test should be taken in differential test of mean vector in multi-population.
