This guide focuses on the Chi-Square Test of Independence (also known as the Contingency Table Chi-Square), which is the most common application in biological and medical research. Comparative verification check:

In a verified analysis, for 2x2 tables, the Chi-Square p-value and Fisher’s p-value should be similar when expected counts are all >5. If they differ substantially (e.g., Chi-square p=0.04, Fisher’s p=0.12), report Fisher’s and note the assumption violation.
