WebReal Statistics Excel Function: The Real Statistics Resource Pack provides the following worksheet function. FISHERTEST(R1, tails) = the p-value calculated by the Fisher Exact Test for a 2 × 2, 2 × 3, 2 × 4, 2 × 5, 2 × 6, 2 × 7, 2 × 8, 2 × 9, 3 × 3, 3 × 4 or 3 × 5 contingency table contained in R1. R1 must contain only numeric values. WebFor example, here we have the second most extreme table we could possibly obtain, and our p-value is 26%. That's a consequence of a, the discreteness, and b, demanding a demanding a exact test. It is what it is. so the Fisher's exact test doesn't distinguish between rows and the columns, transpose the table, you get the same p value out. This 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 … See more Several methods exist to calculate Fisher's test, and this calculator uses the summing small P valuesmethod.
