The following table describes the exact versions of three of the tests available in the Contingency platform.
Performs Fisher’s Exact test for an r x c table. This is a test for association between two variables. Fisher’s exact test assumes that the row and column totals are fixed, and uses the hypergeometric distribution to compute probabilities.
This test does not depend on any large-sample distribution assumptions. This means it is appropriate for situations where the Likelihood Ratio and Pearson tests become less reliable, like for small sample sizes or sparse tables.
