WebOct 21, 2008 · The Fisher exact test is based on the probability of obtaining a table more extreme than the observed table. For example, for the 2x2 case when both row and column totals are fixed, the test statistic is the frequency of the row 1, column 1 cell. This is compared to the hypergeometric distribution. 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.
