Fisher's Exact Test for Small Tables

Fisher's exact test is a statistical significance test for 2x2 contingency tables. It is often used when sample sizes are small and the data are categorical. The test helps scientists check whether two variables may be related.

Unlike the chi-squared test, Fisher's exact test does not estimate th...

Fisher's exact test determines the significance of a nonrandom relationship between two categorical variables in a two-by-two contingency table.

Unlike the chi-square test, which approximates the probability of observed outcomes, Fisher's test yields an exact P-value.

It helps analyze unequally distributed data with small ...
