基于集对分析联系数的体育统计相关系数研究

通过对随机抽取的本校地理系93级52名学生两个学期体育成绩与数学成绩作相关性分析和优中差同异反分类统计，发现传统体育统计相关系数r的计算结果中有值得进一步推敲的地方。运用集对分析（SPA）的同异反分类统计可充分利用原始数据提供的信息，两种方法的综合应用可提高观察数据处理结论的可靠性和准确性。

A Study on the Relevant Coefficient in P. E. Statistics Based on SPA

Choosing accidentally 52 students in Grade 93 of Geography Department of ZNU,we compared their P. E. scores with their maths scores of two terms,did some relevant analysis and worked out a counter-statistic of the similarities and differences of the excellent,fair and poor students. In the end we found that some improvements should be made if we applied the traditional P. E. statistic to count the relevant coefficient "r". But we might make the full use of the information provided by the original data if we use the counter-statistic of the similarities and differences based upon SPA. It will be more reliable and accurate to observe the result of data disposal by using two methods.
