Fisher Exact Test Calculator 2x2 - Fisher' exact test - wikipedia, Fisher's exact test is a statistical significance test used in the analysis of contingency tables. although in practice it is employed when sample sizes are small, it is valid for all sample sizes. it is named after its inventor, ronald fisher, and is one of a class of exact tests, so called because the significance of the deviation from a null hypothesis (e.g., p-value) can be calculated. Fisher exact test, Fisher exact test click here for exact (one-sided) analysis of 2x2 contingency tables. the fisher exact test looks at a contingency table which displays how different treatments have produced different outcomes. its null hypothesis is that treatments do not affect outcomes-- that the two are independent..
