Fisher LSD

This post hoc test (or multiple comparison test) can be used to determine the significant differences between group means in an analysis of variance setting. The Fisher LSD 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 and Post Hoc Comparisons. For a discussion of statistical significance, see Elementary Concepts.
