Bonferroni Test

This post hoc test can be used to determine the significant differences between group means in an analysis of variance setting. The Bonferroni test is very conservative when a large number of group means are being compared [for a detailed discussion of different post hoc tests, see Winer, Michels, & Brown (1991)]. For more details, see General Linear Models. See also, Post Hoc Comparisons. For a discussion of statistical significance, see Elementary Concepts.
