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. WebFeb 25, 2024 · Non-parametric statistical tests are used when continuous data is not normally distributed or when data is discrete, so we can’t apply usual parametric methods …

WebFisher's Exact Test. Fisher's exact test is based on the hypergeometric distribution. Consider sampling a population of size N that has c1 objects with A and c2 with not-A. Draw a sample of r1 objects and find a with A. Then. There are possible samples. Of these, is the number of ways of choosing A in a sample of size c1, is the number of ways ... WebSep 25, 2024 · Fisher’s exact test is a non-parametric method for comparing the proportion of categories in two different independent groups (categorical variables) in a contingency table. In Fisher’s exact test, the two independent groups should be measured dichotomously for 2x2 contingency table. For example, responses should be measured as male/female ... WebMar 7, 2024 · It is known for Fisher's exact test that the p-value is exactly calculated but only few levels (the steps) occur so often the test might be too conservative in relation to a chosen alpha level. It is interesting to see that the effect is much stronger for the 400-400 case (red) versus the 400-100-100-100-100 case (blue). can a combi boiler leak gas
