Dunnett's Test

This post hoc test (or multiple comparison test) can be used to determine the significant differences between a single control group mean and the remaining treatment group means in an analysis of variance setting. Dunnett's test is considered to be one of the least conservative post hoc tests [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.
