McNemar's Test vs Fisher's Exact Test
Developers should learn McNemar's test when working on data analysis projects involving binary outcomes with paired or matched samples, such as A/B testing in web development, evaluating changes in user behavior after an update, or analyzing medical or survey data with repeated measurements meets developers should learn fisher's exact test when working on data analysis, machine learning, or research projects that involve categorical data with small sample sizes, as it provides accurate p-values without relying on large-sample approximations. Here's our take.
McNemar's Test
Developers should learn McNemar's test when working on data analysis projects involving binary outcomes with paired or matched samples, such as A/B testing in web development, evaluating changes in user behavior after an update, or analyzing medical or survey data with repeated measurements
McNemar's Test
Nice PickDevelopers should learn McNemar's test when working on data analysis projects involving binary outcomes with paired or matched samples, such as A/B testing in web development, evaluating changes in user behavior after an update, or analyzing medical or survey data with repeated measurements
Pros
- +It is essential for ensuring statistical validity in experiments where observations are not independent, helping to avoid misleading conclusions from standard chi-square tests that assume independence
- +Related to: statistical-hypothesis-testing, chi-square-test
Cons
- -Specific tradeoffs depend on your use case
Fisher's Exact Test

The Verdict
Use McNemar's Test if: You want it is essential for ensuring statistical validity in experiments where observations are not independent, helping to avoid misleading conclusions from standard chi-square tests that assume independence and can live with specific tradeoffs depend on your use case.
Use Fisher's Exact Test if: You prioritize it is especially useful in a/b testing, bioinformatics (e over what McNemar's Test offers.
