Fisher’s mid-p test The fourth test is a modification of Fisher’s exact test, known as Fisher’s mid-p value, as defined by Lancaster (1961). The calculations are made exactly as those done for Fisher’s exact test, except that the probability of a result more extreme is averaged with the

This Is A Fisher Exact Test Calculator For A 2 X 2 Contingency Table. Assumptions for fisher’s exact test random sample. An approach used by the fisher.test function in R is to compute the p-value by summing the probabilities for all tables with probabilities less than or equal to that of the observed table. In the example here, the 2-sided p-value is twice the 1-sided value—but in general these can differ substantially for tables with … See more Fisher's exact test is a statistical significance test used in the analysis of contingency tables.
