摘要:主成分分析、因子分析是多元统计方法中很有价值的两种方法, 但在使用过程中很容易误用和混淆.本文从数学模型、基本思想、数据的标准化和应用方面着手, 探讨了两者的异同, 并且分别进行了实例分析,通过实例分析能够更清楚地理解、区分和运用这两种方法.同时实例分析客观的评价了学生的成绩,为教学计划的安排提供有力的依据,具有很大的现实意义。39421 毕业论文关键词:因子分析;主成分分析;考试成绩;学生成绩评价
Application of Multivariate Statistical Analysis in The
Evaluation of Student Performance
Abstract : Principal component analysis, factor analysis and cluster analysis of multivariate statistical methods are two very valuable, but in the course easily misused and confused. From the mathematical model, the basic idea, standardization and application data aspects, discussed the similarities and differences between the two. And case analysis were carried out by case analysis I believe we will be more clearly understood, distinguish and apply these two methods. While examples objective analysis is to evaluate student achievement for the purpose of comprehensive scientific evaluation by providing for the arrangement of teaching programs a strong basis, but also has great practical significance.
Key words: Principal Component Analysis; Main Component Analysis; The Examination Results; Evaluation of Student Performance
