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 ... WebThe Chi-Square and Fishers Exact Test can assess for independence between two variables when the comparing groups are independent and not correlated. The chi-squared test applies an approximation assuming the sample is large, while the Fisher's exact test runs an exact procedure especially for small-sized samples. WebAug 18, 2014 · Moreover and WAY MORE IMPORTANT: Chi square is an approximation, where Fisher is the exact test. We are getting more and more to the point where Chi square tests (or even the more reliable G-tests) are not even needed anymore.
