The test based on the hypergeometric distribution (hypergeometric test) is identical to the corresponding one-tailed version of Fisher's exact test. Reciprocally, the p-value of a two-sided Fisher's exact test can be calculated as the sum of two appropriate hypergeometric tests (for more information see … Meer weergeven In probability theory and statistics, the hypergeometric distribution is a discrete probability distribution that describes the probability of $${\displaystyle k}$$ successes (random draws for which the object … Meer weergeven Working example The classical application of the hypergeometric distribution is sampling without replacement.
