WebSep 28, 2024 · Step 1: Find Dunnett’s critical value. Using α = .05, group sample size n = 10 and total groups = 3, Dunnett’s table tells us to use a value of 2.57 in the critical value calculation. Next, we can plug this number into the formula to find Dunnett’s Critical value: Dunnett’s Critical value: td√2MSw/n = 2.57√2 (23.3)/10 = 5.548 WebNov 29, 2024 · The common wisdom is that Fisher’s method tend to values low p-values, instead of consistently low p -values. An alternative to Fisher’s method is Stouffer’s method. The idea is to transform the p -values to z -scores, then compute a combined z -score by averaging the individual z -scores. E.g. if Φ ( ⋅) is the standard normal cdf ...

WebOct 17, 2024 · Summary: chi-squared vs Fisher’s exact test Here is a summary of the properties of the two tests: Generally, Fisher’s exact test is preferable to the chi-squared test because it is an exact test. The chi-squared test should be particularly avoided if there are few observations (e.g. less than 10) for individual cells.
