原始分数的转换

THE TRANFOMATION OF THE PRIMARY SCORES

首先简述分数转换的基本目的要求，然后对原始分数整体是否服从正态分布进行ｘ２检验，给出正态分布下和非正态分布下的分数转换公式．

This paper briefly expounded the basic purpose and requirement of score transformation, and used the x 2_test to determine whether the primary scores obey normal distribution. The score transformation formulae for both normal and abnormal distribution were given.
