WebNext, Fisher’s exact test results are displayed. Here also, the p-value (0.044) is lower than the significance level 0.05. Fisher’s exact test also leads to a rejection of the null hypothesis. Notice that the p-value obtained under the Chi-square test is slightly lower than the one associated to Fisher’s exact test. WebIn my case, the rank sum test has the largest p-value, sign test is the medium, signed-rank is the smallest. Therefore, it has more power. That's not how you decide a test has more power - a lower p-value in respect of one sample may simply be due to the vagaries of that sample, whereas power is about the behavior across all random samples ...
