This is a Fisher exact test calculator for a 2 x 2 contingency table. The Fisher
exact test tends to be employed instead of Pearson's
chi-square test when sample sizes are small.
The first stage is to enter group and category names in the textboxes below. Note:
You can overwrite "Category 1", "Category 2", etc.
Imagine, for example, that you have collected data on smoking habits, and want to
find out whether smoking is related to gender - then you could have "Male" and "Female"
as the two groups, and "Smoking" and "Non-Smoking" as the two categories.
