Fisher exact test bonferroni
Web1 Answer. If you have used Fisher's exact test on a 2x2 table, then your p-value reflects the probability of obtaining cell counts as deviant (or more deviant) as what you observed if the proportions of the margins were fixed at the observed values. This is similar to the sort of question that is answered by a chi-square test of independence ...
