【摘要】 以一个实验研究为例,对无交互作用的协方差分析和有交互作用的协方差分析在前后测实验研究中的应用进行阐述,并与本文设计的"差值的方差分析"方法相比较,结果表明本文设计的"差值的方差分析"的结果与协方差分析结果相吻合。更多还原

【Abstract】 With an experimental study,the application of covariance without interaction and with interaction in experiment with pre-measurement and post-measurement was discussed.And comparing with the "analysis of covariance for difference value" designed by the authors,the two analysis methods had the similar results.更多还原
