测验的测量及统计分析

用数理统计的方法，对不同团体和各团体总体测验结果的集中量数、差异量数、数学分布、信度、区分度和难度进行了计算分析。讨论了信度、区分度与难度之间的关系及具体取值范围。用集中量数和差异量数定量地分析了引起偏态分布的原因，此研究分析过程有助于客观地评价任何教育测验的质量和被测验对象的真实能力及知识水平。

The Examination Measurement and Statistic Analysis

The results of educational examination are studied using the method of mathematical statistics. Also, the concentrated quantities,different quantities, probability and mathematical distribution,related coefficient,differentiality and pass rate of total examination results of different communities and each community are concretely computed and analysed. Meanwhile,the relationships among related coefficient differentiality and pass rate as well as the concrete range of value taking are discussed.The cause resulting in the deviation distribution is quantitatively analysed using the concentrated quantities and difference quantities. This process of the study and analysis is helpful to evaluate the qualities of any kind educational examination and the real ability as well as knowledge level of the examinees.
