检验法在检验学生成绩中得应用摘 要在对学生成绩分析时,采纳数理统计中得检验法可以方便有效地得出相关数据。以某初中全体学生得数学成绩为总体,采纳卡方拟合检验法来检验初三学生得数学成绩近似得服从正态分布,以及检验其相应得方差就是否正确,完成对考试成绩客观准确得分析,充分了解学生得学习情况。利用卡方分布检验中重要应用列联表独立检验对学生数学成绩与学校对其所培育得重视程度得关系进行讨论,这可以帮助我们去发现教育教学中所要发生得问题,为教育质量得认定与评价提供有效得保障。关键词: 检验法;假设检验;卡方分布The application of -test in test scores of studentsAbstractIn the analysis of student achievement, using the test statistics can be conveniently and effectively get the relevant data、 A junior high school student with math scores for overall, using the chi-squared fit to test the students mathematical results approximately obey the normal distribution, and test the corresponding variance is correct, plete analysis of test scores of objective and accurate, the full understanding of students learning、 Using the card application distribution test of contingency table test for students to study mathematics achievement and school emphasis on its culture, which can help us to discover what happens in education and teaching, to provide an effective guarantee for the monitoring and evaluation of the quality of education、Keywords: -test, hypothesis testing, distribution目 录中文摘要...................................................
