WebThe Fisher Exact test on an r × c table is sometimes referred to as a Fisher-Freeman-Halton test [1]. Indeed, the help on the R function you mention makes it quite clear that it works on r × c tables, and gives several references that relate to the r × c case. [1] Freeman, G.H., & Halton, J.H. (1951). WebFisher'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 . Yates' continuity correction can be used alongside chi-square.

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 ...

In that case, the null hypothesis tested by Fisher's test can be formulated as both the ORs being equal to 1. You could calculate the ORs by splitting into two 2 × 2 tables, or simply by using a logistic regression, where the coefficents (forget the intercept) are log odds ratios.
