Fisher's method combines extreme value probabilities from each test, commonly known as "p-values", into one test statistic (X ) using the formula where pi is the p-value for the i hypothesis test. When the p-values tend to be small, the test statistic X will be large, which suggests that the null hypotheses are not true for every test. When all the null hypotheses are true, and the pi (or their corresponding test statistics) are inde… WebApr 27, 2024 · We will perform Fisher’s Exact Test using the following hypotheses: H 0: Gender and political party preference are independent.
