The job of Fisher's exact test with 2 x 2 or 2x 3 contingency table is already easily done by others. However, the one with n x m contingency table hasn't found , or with bad computation.
Web9 Feb 2024 · In Fisher's exact test, you have a different hypothesis. You assume that the ratio good/bad is 13 / 15, regardless of the sex, and ask whether the observed ratio for the boys, 6 / 7 significantly differs from that. It doesn't, but, again, if you had more data, it might: fisher_exact ( [ [6000, 1000], [7000, 1000]]) results in p ≈ 0.0014.

WebThis is a test for the null hypothesis that 2 independent samples have identical average (expected) values. This test assumes that the populations have identical variances by default. Parameters: a, barray_like. The arrays must have the same shape, except in the dimension corresponding to axis (the first, by default).
