Bonferroni correction
In statistics, the Bonferroni correction is a method used to counteract the problem of multiple comparisons. It is named after Italian mathematician Carlo Emilio Bonferroni for the use of Bonferroni inequalities, but modern usage is often credited to Olive Jean Dunn, who described the procedure in a pair of articles written in 1959 and 1961.

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, 1985, pp.140-197). For more details, see the General Linear Models chapter. See also, Post Hoc Comparisons . For a discussion of statistical significance, see Elementary Concepts .
