文理科数学成绩差异的统计分析

为了分析文科生与理科生的数学成绩是否有显著性差异，选取同一个老师教的文科班和理科班的数学成绩，通过SPSS软件对其进行统计分析，首先由拟合优度K-S检验得出学生的数学成绩是服从正态分布的，然后通过相互独立的两组样本的t检验进行文理科平均成绩的比较，从而得出结论：文科生的数学成绩均值普遍低于理科生的数学成绩均值。文章分析了造成这种现象的原因，并给出了提高文科生数学成绩的四条策略。

Statistical analysis of the difference in mathematics scores between arts and science

In order to analyze whether there is a significant difference in mathematics scores between the students of arts and science,we select the mathematics scores from the students of arts and science which is taught by the same teacher,it was accomplished by SPSS software.First,we find that the students' mathematics scores are obeying normal distribution by the goodness of K-S examination,then we compare their average scores through the Independent Sample t Test.Thus,we draw the conclusion:the scores of the stu...
