Topic 9: Analysis of Variance (ANOVA)

Analysis of Variance (ANOVA) is a group of methods that is used to establish whether or not the means of three or more groups are reliably different. In this sense, ANOVA is closely related to t-tests (see Topic 4): To find out if three groups A, B, C have different means, we could use t-tests to compare A to B, A to C, and C to B. ................
