WebThe Fisher’s exact test is just that, exact. 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 ...
