WebJun 18, 2024 · Sample size should NEVER be calculated based on the observations used for the actual analysis. An alterative for using fishers exact test for calculating sample size is to use proportions. Second you ask about correction for multiple testing. Unless you are looking at 1000 or more tests, I would never recommend correcting for multiple testing.

The only difference is that rather than compute the pooled SD from only the two groups being compared, it computes the pooled SD from all the groups. If all groups are sampled from populations with the same SD, using all the data to compute the pooled SD gives a more accurate value ...

It seems unwise to do Fisher's exact test with ordinal data - you throw away so much of the information. It's possible to do exact tests by using some statistic that incorporates ordinal information. Expected cell counts less than 5 shouldn't be a problem - expecteds that are fairly similar can go down a fair bit smaller and still get an an ...
