Liu Qin-long · China Sports · 2003
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.
