摘要
以教育统计与测量理论为基础,根据学生考试原始成绩,应用MATLAB工具按照κ检验的方法验证本次考试成绩服从正态分布,应用χ2检验法对其进行定量分析,证明了本次考试低分人数偏多的主要原因是试题难度偏大,指导命题教师在以后的同类考试中,应适当降低难度.
According to the students＇ test raw scores, based on the education statistics and measurement theory, the MAT- LAB tools is used in testing normal distribution of this exam achievement by K inspection. By the application of χ2 inspection for quantitative analysis, main reason for the number of lower test scores is that the test difficulty is too large. So teachers should aappropriately reduced difficulty of the similar exam in the future.
