Fisher's Exact Test Calculator for a 2x3 Contingency Table. This calculator uses the Freeman-Halton extension of Fisher's exact test to compute the (two-tailed) probability of obtaining a distribution of values in a 2x3 contingency table, given the number of observations in each cell. Please enter the necessary parameter values, and then click ...
Definition. Fisher's Exact Test is used to determine whether there is a significant association between two categorical variables in a 2×2 contingency table. It's particularly useful when sample sizes are small or when cell values are less than 5. The test calculates the exact probability of observing the data assuming the null hypothesis of independence is true.

Table input data format: First row contains comma-seperated column names. Subsequent rows contain row name, followed by count data, also comma-separated. ...
Frequently Asked Questions 1. When should I use Fisher's Exact Test? Use Fisher's test when analyzing 2x2 contingency tables with small sample sizes (total n . 20) or when any cell count is less than 5.. It's ideal for exact probability calculations in randomized experiments or observational studies with limited data.
Fisher’s Exact Test is used to determine whether or not there is a significant association between two categorical variables. It is typically used as an alternative to the Chi-Square Test of Independence when one or more of the cell counts in a 2×2 table is less than 5.

Compute the exact two-tailed probability of obtaining a particular distribution of values in a 2x3 contingency table using the Freeman-Halton extension to Fisher's exact test, given the number of items or observations in each cell. Knowing the exact probability of observing a given distribution of values can be very useful in analytics studies that rely on categorical data.
The Fisher’s Exact Test Calculator (2×3) outputs an exact p‑value for your contingency table. A low p‑value (typically less than 0.05) suggests that the association between the categorical variables is statistically significant, leading to rejection of the null hypothesis.
