WebOct 16, 2024 · Chisq and Fishers post hoc tests. I am trying to do post hoc tests on both a chisq and a Fisher exact test. The dataframe I am using is a 2x3. I ran a chisq test which produced a significant p-value, but when I checked the expected values there were some less than 5, so I ran a Fishers exact test, which also returned a p-value less than 0.05.
Fisher's exact test is a statistical significance test used in the analysis of contingency tables. Although in practice it is employed when sample sizes are small, it is valid for all sample sizes. It is named after its inventor, Ronald Fisher, and is one of a class of exact tests, so called because the significance of the deviation from a null hypothesis (e.g., P-value) can be calculated exactly, rather than relying on an approximation that becomes exact in the limit as the sample size grows to infi… flock of wild turkeysWebJul 10, 2014 · Fisher's LSD is indeed a series of pairwise t-tests, with each test using the mean squared error from the significant ANOVA as its pooled variance estimate (and naturally taking the associated degrees of freedom).
