What is Fishers exact test?
Fisher’s exact test is a significance test that is considered to be more appropriate for sparse and skewed samples of data than statistics such as the log likelihood ratio (G^2) or Pearson’s Chi-Squared test (X^2). The paper “Fishing for Exactness” gives a fairly detailed description of Fisher’s exact test relative to these other tests.
