从体育统计处理系统的角度重新认识统计总体

Re-recognizing the Statistical Population from the Angle of Statistical Processing System in Physical Education

统计总体是研究目的的具体化和定量化,是数据分析的起点和归宿。根据体育科学定量研究的目的,将统计总体概括地分为两大类:1以获得关于研究对象特征为目的的统计总体;2以比较不同处理效应为目的的统计总体。分析了与相应统计总体匹配的常用统计方法,指出统计总体是将物化的研究对象转化为统计符号信息的首要环节,确定统计总体是体育统计分析的关键环节。同时,从统计处理系统的角度指出提高统计处理的效果应当注意两个问题:1防止统计推断的误用;2保持样本与总体的同质。

Statistical population is the specification and quantification of research targets, and starting point and destination of data analysis. According to the purpose of quantity research in Physical Education, the statistical population can be divided into two categories: 1) the statistical population whose purpose is to obtain the information of research subject's characteristics. 2) the statistical population whose purpose is to deal with different effects. So the author further analyzes the popular statistical methods according with corresponding statistical population. The result points out that statistical population is the principal sector in changing definite research subject into statistical semiotic information, so the choice of statistical population is the key sector of statistical population analysis in Physical Education. Meanwhile, the author points out that in order to improve the effects of statistical processing from the angles of statistical processing system, two problems should be paid special attention to: 1) to prevent the misuse of statistical deduction; 2) to keep the same quality of the sample and the population.
