It does not use an approximation like the chi-square test and therefore remains valid for small sample sizes. When the sample size becomes large enough the p-value generated from a chi-square will approach that of a Fisher’s exact. Fisher’s exact also has the benefit of being valid at large ...

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. 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 ...
