摘要
利用传统计算方法和使用制表软件Excel计算的方法,对多个小样本的平均数(均数)、标准差、合格率(及格率、达标率)进行合并计算,最后得出一个总体的平均数、标准差和及格率.使合并计算方法更加简洁,方便广大体育工作者在体育管理、体育教学和体育科学研究工作中,对体育统计数据进行分析对比.
By means of traditional calculation method and the calculation method adopted in Excel,this paper is aimed at combining the calculation of the average,the standard deviation and the passing rate of various small samples in a bid to work out a general average,standard deviation and a passing rate.This method could make the calculation much easier and could also facilitate those engaged in Physical eduction to conduct data analysis and comparision in P.E management,teaching as well in P.E study.
