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 exactly, rather than relying on an approximation that becomes exact in the limit as the sample size grows to infi…
WebFisher's Exact Test. Fisher's exact test is based on the hypergeometric distribution. Consider sampling a population of size N that has c1 objects with A and c2 with not-A. Draw a sample of r1 objects and find a with A. Then. There are possible samples. Of these, is the number of ways of choosing A in a sample of size c1, is the number of ways ...
