Web1. 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 ... WebThe Fisher test is performed only if N≤300. Note that P A and P B are both non-directional (two-tailed). The chi-square test is performed only if at least 80% of the cells have an …
