| Abstract: | In this paper,the author evaluates the overall quality of students through Principal Component Analysis(PCA) which started from the correlation matrix of the sample,by randomly selecting 20 students from Agricultural University of Hebei as indicators to analysis.Eventually,A for-factor expression was proposed to reflect the overall quality of students and the principal component of PCA expression.It shows that the PCA method is more scientific than the traditional methods and practical for comprehensive scientific evaluation of the quality of students.This provides a theoretical basis. |
