课程设计论文 应用多元统计方法对部分省市经济发展的研究 The Research of College Students’ Grades by Multivariate Statistical Method 学 院：理学院 专 业：应用统计学 姓 名：徐茂发 指导教师：周兰锁 职 称：讲 师 论文提交日期：二Ο一七年五月 摘 要 随着时代的发展和社会的进步，人们对人力资源的开发越来越重视，用人单位在跳远人才时，对应聘者的科学文化水平和知识结构要求越来越高，特别是随着高等教育的迅速发展、招生规模的不断扩大，知识的快速更新，对生源结构和教师结构都产生了很大的影响。作为人才培养的高地，高等学校如何提高教学质量，为社会培养有用的高级人才，一直是教育界研究的重要课题。 本文抽取2013级理学院统计学专业一班36名学生和2012级理学院统计学专业一班28名学生的大二学年成绩作为样本，运用聚类分析，因子分析的多元统计方法以及采用SPSS19.0分析软件对数据进行定量的分析。首先采用了统计方法对原始数据进行了预处理，采用聚类分析方法把学生分为四大类，然后用因子分析方法把繁多的课程总结成两大主因子，给出了因子得分模型。 通过分析研究，我们得出，学生的总成绩高低并不能反映学生能力的大小，通过权衡各科比重，得到学生综合成绩，才能反映学生真正学习能力。而且通过因子分析，也可以看出学生比较薄弱的科目，也对今后教学给出了侧重点。 关键词：多元统计 聚类分析 因子分析 The Research of College Students’ Grades by Multivariate Statistical Method Abstract With the development of the times and social progress, people pay more and more attention to the development of human resources, the employing units in the selection of personnel, which requests applicant more and more high level in the scientific and cultural level and knowledge structure. Especially with the rapid development of high education, expanding enrollment and rapid updating of knowledge which bad a great influence on students and teacher structure. As training ground, has always been an important research subject in the educational circles, for how to improve the teaching quality of higher education and the training of high-level personnel useful to society.. This paper bases on the grades of the 36 students from class one of 2013 professional faculty of science statistics and the grades of the 28 students from class one of 2012 professional faculty of science statistics. It applies cluster analysis, multivariate statistical methods of factor analysis and SPSS19.0 analysis software for quantitative analysis of the data. First, it adapts the original data to get grade point pretreatment and uses cluster analysis method to divide the students into 4 parts. Then, it uses factor analysis method to divide the wide range
