WebJan 28, 2024 · On the other hand, the Fisher’s exact test is used when the sample is small (and in this case the p p -value is exact and is not an approximation). The literature indicates that the usual rule for deciding whether the χ2 χ 2 approximation is good enough is that the Chi-square test is not appropriate when the expected values in one of the ...
