WebJul 10, 2014 · And, Fisher's test wasn't crafted under a Neyman-Pearson theory of statistical inference. It is important to keep in mind that, when Fisher proposed the LSD, he didn't really consider multiple testing an important problem because he didn't consider the significance cutoff a hard and fast rule for deciding whether results were important or not. WebThe Fisher exact test computes the p -values by finding the probabilities of all possible combinations of 2 × 2 tables that have the same marginal totals (the values in cells m, n, r, and s) that are equal to or more extreme that the ones observed.
