WebSep 2, 2024 · 0. I have a 2x2 contingency table with the following values: A = 20, B = 10, C = 200, D = 300. As you can see, the sample size is much larger than 20, the recommended sample size if one were to use the Fisher's exact test. I read this post that suggested to do a simple N − 1 N. However, I don't quite understand why or how to do this.

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.
