三种常用体育综合评价方法的比较研究——对2003-2004NBA现役优秀中锋竞技水平的排名

Comparative Research on Three General Multi-evaluation Methods——Ranking of 2003-2004 NBA Super Centers on a Scale of Athletic Ability

通过选用目前在体育评价中常用的三种综合评价方法:RSR法、主成分分析法和加权积分法,对2003-2004NBA现役优秀中锋竞技水平的评价、比较得出:RSR法评价属综合评价,但各指标在综合水平中的地位和作用是均等的,没有分出各指标的重要性;主成分分析法具有高度的数据化和减少变量个数特点,但原始数据需先进行标准化处理且各指标的权重由方差大小来确定,与实际要求不相符合,评价失真;加权积分法评价,通过咨询专家来确定评价指标的权重,再乘以各指标的位置百分法得分,得出综合评分,既有实践经验又有科学评分,是现行三种评价方法中的最优评价方法。

By the methods of three general multi-evaluation (Principal Component analysis, RSR and weighted integrations) which are used in the sport evaluation system, compare the athletic level of NBA super centers on a scale of athletic ability between 2003-2004 NBA, we made some conclusions: RSR, although the category of the multi-evaluation methods, can't show us the import difference between different indexes. Principal Component analysis, featured with numerous data though importance indexes are based on variance, can not meet the real demands and turns to be inaccurate. Weighted integration can works out indexes importance through expert investigations, then multiply the percentage of each index position and get the unified mark, which is the best evaluation method, because it includes practical experience and scientifical mark.
