Fisher-yates exact test
WebUse Fisher's exact test to analyze a 2x2 contingency table and test whether the row variable and column variable are independent (H 0: the row variable and column variable are independent). The p-value from Fisher's exact test is accurate for all sample sizes, whereas results from the chi-square test that examines the same hypotheses can be ... WebThe Yates correction is a correction made to account for the fact that both Pearson’s chi-square test and McNemar’s chi-square test are biased upwards for a 2 x 2 contingency table. An upwards bias tends to make results larger than they should be. If you are creating a 2 x 2 contingency table that uses either of these two tests, the Yates ...
