竞赛评分结果的偏移量修正法

On the method of modification of partial moved data in competition

偏移量修正法,每个评委打出的分数基本上服从正态分布,据此将评委给出的原始分进行标准化,得到较为公正的最后分数。为更好地说明该方法,还介绍了普通意义上的评分方法,即去掉一个最高分,去掉一个最低分,然后求算术平均。分析了竞赛评分系统采用的评分方法相对于普通评分方法的优点。并且,简单介绍了竞赛评分系统的数据库设计,以及具体程序的实现。通过三组普通评分方法得出的分数和软件计算得出的分数的数据比较,验证了竞赛评分系统采用的计算方法的合理性。最后,从应用效果的角度,分析了评委和选手的接受程度,以及该系统的可操作性。

This paper primarily introduces the method of modification of partial moved data in competition marking results. This method standardizes the original marks of referees and justly gets eventual marks according to marks given by every referees and the marks are basically in normal distribution. In order to explain this method better, this paper still introduces a common marking method that a highest mark and a lowest mark are removed then arithmetic average mark is calculated. The advantage of marking method in competition marking system is analyzed in contrast to common marking method. Moreover, design of data base and realization of concrete program in competition marking system are simply introduced. Through comparison of three groups of data between points of common marking method and points of software marking method, rationality of calculation method in competition marking system is validated. Finally, acceptance degree of referees and players and maneuverability of this system is analyzed from the point of view of application.
