Web$\begingroup$ Is there a way to calculate p-values from odds ratio?In fisher.test I don't understand the alternative hypothesis argument. It says alternative hypothesis must be one of "two.sided", "greater" or "less" and that the alternative for a one-sided test is based on the odds ratio, so alternative = "greater" is a test of the odds ratio being bigger than or? what … WebIf you entered data with two rows and two columns, you must choose the chi-square test (sometimes called the chi-square test of homogeneity) or Fisher's exact test.. Chi-square and Yates correction. In the days before computers were readily available, people analyzed contingency tables by hand, or using a calculator, using chi-square tests.

The tests discussed so far that use the chi-square approximation, including the Pearson and LRT for nominal data as well as the Mantel-Haenszel test for ordinal data, perform well when the contingency tables have a reasonable number of observations in each cell, as already discussed in Lesson 1. WebApr 23, 2024 · You do a Fisher's exact test on each of the 6 possible pairwise comparisons (daily vs. weekly, daily vs. monthly, etc.), then apply the Bonferroni correction for multiple tests. With 6 pairwise comparisons, the P value must be less than 0.05 / 6, or 0.008, to be significant at the P < 0.05 level.
