单因素方差分析用于完全随机设计的多个样本均数间的比较,其统计推断是推断各样本所代表的各总体均数是否相等。本文简单介绍了单因素方差分析方法,然后利用excel进行检验并得出相关结论。
One-way analysis of variance (ANOVA) was used to compare the mean of multiple samples in a completely randomized design. The statistical inference was to deduce whether each population represented by each sample was equal. This article briefly introduces the single-factor analysis of variance, and then use excel to test and draw the relevant conclusions.
