摘要
T检验是体育统计学中经常用到的检验方法,然而,存在大量不顾数据分布类型,样本容量大小,直接套用统计软件,滥用T检验行为.从理论上对T检验做两点注记,然后利用R软件进行随机模拟进一步证实注记.
T-test method is usually applied in sports statistics.However,there is a lot of abuse of T-test,in which data set was put into statistical software directly without considering the types of data distribution set and its sample size.This paper offered two notes on T-test theoretically,and further proved the notes through stochastic simulations by R software.
