基于主成分因子分析的教学质量综合评价

Comprehensive evaluation of teaching quality based on principal component analysis

在阐述主成分因子分析的基本方法的基础上,以622份期末教学质量评价表为基础,对原有采集数据指标进行初步整理,运用IBM-SPSS统计软件和主成分因子分析的基本原理对6类评价指标进行统计学相关性分析,通过计算采样数据的特征向量、特征值、累计贡献率找出3个主成分因子。

The paper states the basic method of the principal component analysis. Based on the samples of 622 final teaching quality evaluation, then, the work indexs of the samples, and statistics the correlation analysis of 6 kinds of evaluation index throgh using IBM SPSS statistical software and principal component analysis method. It also calculates the characteristic vector, the characteristic value and the cumulative contribution rate of the sampling data to find three principal component factors.
