One way 和Two way ANOVA分析的区别是啥
那么什么叫关心的变量呢? 观测变量,结果变量。
两个自变项(或属性变项、类别变项)对於某个依变项(观察变项)交互作用的影响。
比如说你想观察儿子的身高(连续变量),那么你可以讨论:父亲身高对儿子身高,以及母亲身高对儿子身高的影响。你认为影响观测样本的量有两个,一个是父亲身高(必须分级:高,中,低),一个是母亲身高(必须分级:高,中,低)。 每个小组的样本量要一样;
那么这个时候就要用:two-way ANOVA进行分析了。检测的H0假设是:父亲的身高对儿子身高没有影响;母亲的身高对儿子的身高没有影响;父亲身高和母亲身高之间没有相互作用。 H1假设是:。
==============================================
介绍的非常详细;
没有交叉的话,可以认为两个因素对结果没啥 叠加影响。
=========================================
=======================
使用prism进行two way ANOVA分析:
不同天,以及不同组 对结果的影响。
结果如下:
多重比较结果: 不同天,两组之间是否有显著性差异:
