Fischer randomization test
WebFisher'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 … Web, the randomization test will falsely reject the null less than 100 of the time. We don’t have to rely on large samples or approximations to achieve this, though sometimes we can …
