MedCalc's free online Fisher exact probability calculator - analysis of a 2x2 classification table.
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.
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.
Origin of Fisher's Exact Test: This test was formulated by Ronald Fisher in 1935. The Fisher's Exact Test Wiki is an excellent source of its history and background, as well as its statistical theory. Attribution . 2016 Navendu Vasavada
The Fisher Exact Test Calculator determines the significance of associations between categorical variables in 2x2 contingency tables. It's particularly useful for small sample sizes where chi-square tests are inappropriate. Researchers use it in medicine, biology, and social sciences to analyze experimental results and observational studies ...

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.
Fisher's Exact Test Fisher's Exact Test is a classical statistical estimate of the significance of association between two classifications of categorical data—this is the two-sided test. Enter numbers in the boxes to the right corresponding to counts for each category for two groups and press "Compute" to see a corresponding p value that estimates how likely the association is— the smaller ...

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.
This page also provides an interactive tool allowing researchers to conduct Fisher's exact test for their own research. Following is a condensed introduction. About Fisher's exact test. The Fisher exact test for 2 x 2 tables is used when members of two independent groups can fall into one of two mutually exclusive categories.

Exploring the Fisher's Exact Test Calculator with Practical Examples Example 1: Consider a table with one parameter value x and another y. After inputting these values and performing the calculation, the Fisher's Exact Test Calculator provides an exact p-value, indicating whether the observed association could be due to chance.
The Fisher’s Exact Test Calculator uses Fisher’s Exact Test which is a statistical method used to determine if there are nonrandom associations between two categorical variables. It is particularly useful in situations where sample sizes are small, making it an essential tool for researchers, data analysts, and statisticians. ...
The Fisher’s exact test is a statistical test commonly used in medical research. It studies whether or not there is a statistical association between two variables. For example, it may find whether or not diabetes is associated with the risk of heart disease.
