Chapter 14 – Analysis of Variance (ANOVA)
... Chapter 14 – Analysis of Variance (ANOVA) We have already seen two-sample tests for equality of the means in chapter 10. What if there are more than two groups? Answering the question relies on comparing variation among the groups to variation within the groups, hence the name. The null hypothesis f ...
