摘    要

 本文首先分析了學生綜合測評的現狀，簡單比較三種主要評價方法的優缺點，提出用多元統計分析方法解決問題的可行性。其次簡單介紹因子分析的基本思想、主要概念以及SAS系統的相關知識。接著根據實際情況建立數學模型，利用SAS進行求解，并給出結果分析。綜合得分將作為測評的最后成績，以此來衡量一個學生的綜合能力，并作為評選獎學金的依據。

關鍵詞：多元統計 因子分析 綜合測評

Abstract
 In this paper, multivariate statistical analysis was used to eva luate 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 eva luation 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.
