摘要/Abstract

摘要： 该文对近年来国内外盛行的基于项目的方差分析做了一个系统深入的探讨。作者首先指出，实验中的项目也可以像实验中的被试一样作为实验单位。据此，从理论上可以区分出两类基本实验设计：项目内（组内）设计和项目间（组间）设计。这样相应于基于项目的实验设计，基于项目的方差分析就可以被用于实验数据的处理了。进行基于项目的方差分析的意义在于，能把实验中得到的结果推广到实验项目所代表的项目总体或类似的项目总体上去。作者最后指出，对实验数据进行基于项目的方差分析的必要条件是项目为随机变量，并不是在所有的实验中都可以进行基于项目的方差分析。

Abstract: A deep exploration of Analysis of Variance by Items (ANOVA by items) had been made in this paper, which is very popular in recent years both at home and abroad. The author first proposed that items in an experiment could also be seen as experiment units like subjects. Therefore, two kinds of basic experimental designs could be distinguished theoretically: Between-items design and Within-items design. Accordingly with ANOVA by subjects, ANOVA by items can also be used to the same experiment for data processing based on its experimental design by item. But at the end of this paper the author indicated that it is not always that ANOVA by items could be used for data processing because items in some experiments are constant rather than random variable. Implications of using ANOVA by items for data processing was also discussed.

Key words: experiment units, between-items design and within-items design, ANOVA by items
