What types of McNemar's test does this calculator support?

This calculator supports five versions of McNemar's test: Standard McNemar's test, with Edwards correction, with Yates correction, exact p-value binomial test, and mid-p-value binomial test, allowing users to choose the appropriate method for their paired binomial data analysis.

What kind of data do I need to provide to use the McNemar's Test Calculator?

You need to provide the paired binomial data values labeled a, b, c, and d, which represent the counts from your study design comparing two related measurements or conditions, such as patient results before and after treatment.

Can this calculator be used as an exact McNemar's test calculator?

Yes, this tool can serve as an McNemar's exact test calculator, offering the exact p-value binomial test and mid-p-value binomial test options alongside the approximate chi-squared versions.

What is McNemar's test used for in practice?

McNemar's test is used to analyze paired binomial data, typically when assessing differences between two related groups or conditions, such as patient outcomes before and after treatment, or exam results before and after an intervention, with a dichotomous variable like positive/negative or pass/fail.
