摘要 无法考察交互作用的三因素设计包括交叉设计和拉丁方设计两种。这两种设计类型较为特殊,所考察的3个因素包括1个实验因素和2个区组因素。尽管这两种设计在实际科研中运用的频率不是很高,但若在合适的场合正确运用这两种设计类型,将有效控制样本量,取得很好的实验效果。由于篇幅限制,本文重点介绍交叉设计的前两种类型。 Three-factor designs that are unable to examine the interactions include crossover design and Latin square design, which can examine three factors, namely, an experimental factor and two block factors. Although the two design types are not quite frequently used in practical research, an unexpected research effect will be achieved if they are correctly adopted on appropriate occasions. Due to the limit of space, this article introduces two forms of crossover design.
