Barnard's Test Calculator

This blog post implements an online Barnard's Test Calculator on a 2 by 2 contingency table for a two-sided test. Barnard's test is computationally intensive, and is not as widely used as Fisher's Exact test. However, many statisticians argue (with reasonable justification) that it is a more powerful test especially for the 2 $\times$ 2 contingency table scenario.

Please fill in the four text areas with integers greater than or equal to zero, but less than or equal to 100 (for computational reasons). Note that the outcomes are the rows of the table, whilst the columns are the categories (also known as treatments).

Category 1: Category 2:
Outcome 1:

Row Sum 1

Outcome 2:

Row Sum 2

Column Sum 1

Column Sum 2
