Bonferroni Adjustment:
Bonferroni adjustment is used in multiple comparison procedures to calculate an adjusted probability 
of comparison-wise type I error from the desired probability 
of family-wise type I error. The calculation guarantees that the use of the adjusted 
in pairwise comparisons keeps the actual probability 
of family-wise type I errors not higher than the desired level, as specified by <img src="/uploads/images/glossary/bonfadj_g_i5.gif" align="bottom" width="38" height="1
