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. WebBoschloo’s exact test uses the p-value of Fisher’s exact test as a statistic, and Boschloo’s p-value is the probability under the null hypothesis of observing such an extreme value of this statistic.

Fisher's exact test is a statistical significance test used in the analysis of contingency tables. Although in practice it is employed when sample sizes are small, it is valid for all sample sizes. It is named after its inventor, Ronald Fisher, and is one of a class of exact tests, so called because the significance of the deviation from a null hypothesis (e.g., P-value) can be calculated exactly, rather than relying on an approximation that becomes exact in the limit as the sample size grows to infi…
