摘    要

 本文首先分析了学生综合测评的现状，简单比较三种主要评价方法的优缺点，提出用多元统计分析方法解决问题的可行性。其次简单介绍因子分析的基本思想、主要概念以及SAS系统的相关知识。接着根据实际情况建立数学模型，利用SAS进行求解，并给出结果分析。综合得分将作为测评的最后成绩，以此来衡量一个学生的综合能力，并作为评选奖学金的依据。

关键词：多元统计 因子分析 综合测评

Abstract
 In this paper, multivariate statistical analysis was used to evaluate students’ comprehensive capacity. It selects the information and computing science professionals 03 Class A students’ survey results for the samples. Firstly, it analyzes the status quo of comprehensive assessment of students, compars advantages and disadvantages of the three main evaluation methods, and it  is feasible to solve the problems by using multiple statistical methods. Secondly, it introduces the basic ideas, concepts of factor analysis and the SAS system. Then, establish mathematical models based on the actual situation, use SAS to solve, and give the results. Comprehensive assessment scores will serve as the final results, as a means of measuring a student's overall capability, and as the basis for scholarship.

Keywords:：Multivariate statistics  Factor analysis  Comprehensive assessment
