Fisher's Exact Test

Enter Values here


This is an online calculator for one-tailed Fisher's Exact Test p-values. It calculates the exact probability that this result would occur as well as the exact probability for all extreme cases. The result shown is the sum of all such extreme cases. In order to use these results, you must first know whether you expect to use a right or left tailed test. This can be determined by knowing whether you expect a positive correlation (upper left and lower right values higher than their expected value) or a negative correlation
