Enter the values of b and c into the calculator to determine chi-squared using the Mcnemar test.
Mcnemar Test Formula
The following formula is the Mcnemar test for calculating chi-squared.
X^2 = (b-c) ^2 / (b+c)
- Where X^2, chi-square, is the relationship between data sets.
- b and c are the values of bc and c in a 2×2 contingency table

Mcnemar Test Definition
A mcnemar test is a formula used for calculating the chi-square value between two tests. This value shows the relationship between those two tests in how closely they match each other.
Example
How to perform Mcnemar Test?
- First, determine the values of B and C.
Set up your 2×2 contingency table between experiments and measure the values of B and C.
- Next, calculate chi-squared.
Calculate X^2 using the formula above.
FAQ
What is chi-squared?
Chi-squared, also known as X^2, is the value of the test statistic between experiments or tests.
