摘要
本文通过对4种测量量表的分析,由如何从等级测量转化等距测量出发,从理论上提出一种题目合理给分的方法,从而减少了考试误差,提高了考试信度并得到了实验上的验证。
With the analysis of 4 kinds of measurement scales, this article theore-tically presents a method of giving item scores in test papers on the basis of how the transformation from categorial measurement to equidistant mea-surement takes place, thereby reducing the test error and increasing the test reliability coefficient. The theorry is justified experimentally.
