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. Web1. It seems unwise to do Fisher's exact test with ordinal data - you throw away so much of the information. It's possible to do exact tests by using some statistic that incorporates …
WebThe generalised Fisher exact test is difficult to compute (Mehta and Patel, 1983, 1986a); it may take a long time and it may not be computed for the table that you enter. If the Fisher exact method cannot be computed practically then a hybrid method based upon Cochrane rules is used ( Mehta and Patel, 1986b ); this may also fail with large ...
