摘要
通过回归分析和方差分析方法的结合,协方差分析方法能够有效地消除混杂因素对分析指标的影响.运用SPSS软件,对某高校六个班一门基础课和一门专业课上下学期的期末成绩进行了协方差分析.结论显示,协方差分析方法能够对教学效率做出更合理的评价.
By the combination of regression analysis and analysis of variance, analysis of covariance can effectively eliminate the confounding effects of factors on the analysis of indicators. By SPSS, analysis of covariance is conducted on six classes about final results of one basic course and one specialized course in a university. At last, it is concluded that the covarianee analysis can make a more reasonable assessment on the teaching efficiency.
