WebFisher's method combines extreme value probabilities from each test, commonly known as "p-values", into one test statistic ( X2) using the formula. where pi is the p-value for the ith hypothesis test. When the p-values tend to be small, the test statistic X2 will be large, which suggests that the null hypotheses are not true for every test.
