WebThis is also known as the chi-square test of independence. Fisher's exact test is used to calculate P values for small sample sizes. It was created for a specific (and rare) experimental design where marginal totals are fixed. It's called an exact test, but that can be misleading because it's only exact if your experiment meets that condition. WebDec 9, 2016 · $\begingroup$ Multiple testing is clearly an issue.

Generally, 90% mortality is used for Fisher's exact test. … WebThe most common use of Fisher's exact test is for 2×2 tables, so that's mostly what I'll describe here. Fisher's exact test is more accurate than the chi-square test or G –test of independence when the expected numbers are small. I recommend you use Fisher's exact test when the total sample size is less than 1000, and use the chi-square or G ...
