Fisher's exact test is a statistical significance test for categorical data, measuring the association between two variables in a 2x2 contingency table. This online tool computes Fisher�s statistics, calculating the hypergeometric probability of the table, and onesided and twosided pvalues, and displaying a visualization of the distribution of pvalues. Unlike most tools, we do not use any approximations, even for tables with very large counts. If you have multiple tables, compute the False Discovery Rate using this tool. Learn more...
