摘　　要：论述了利用正态分布将原始分数转换为标准分数进行处理的分数转换原理;阐明了标准分数的应用方法,对于满分为150分的考试科目提供了一种实用标准分数的处理方法;建立了运用标准分数来比较不同学科测验(包括考试)分数合成时的总成绩或总平均成绩,从而确定个体成绩在团体或总体中相对地位的基本模型和加权模型;使用Visu-al Foxpro作为编程环境,编制了与已使用相关教务管理系统兼容的软件;最后就试点应用的效果进行了比较分析.The principle for transforming original marks into standard ones using normal distribution is discussed.The applied method of standard marks is explained,and a practical handling method of standard marks is posed for the examination courses that the full mark is 150.The basic model and the weighted model for determining the relative position of individual result in group or population are established,in which the total results or the average results of different subjects are compared with the standard marks.By using Visual Foxpro as programming environment,the software compatible with the existing managing system used by educational administration has been compiled.Finally,the results applying both models to the selected units are contrasted and analysed.
