The McNemar Test dialog is shown below. Here, you enter the information that Maritz Stats needs to compute the results of a McNemar Test.

Enter the number of respondents who responded Yes to Option A and No to Option B, as well as those who responded No to Option A and Yes to Option B. Those who responded Yes or No to both options are discarded by the formula, and thus do not need to be entered. If there are fewer than 5 respondents in either cell, then we recommend using the Binomial Test to conduct this comparison.
The confidence level indicates the degree of confidence that the interval actually encompasses the unknown population parameter variable. Usage of the 95% confidence level is standard practice and has been set as the default. However, you have the option of being more stringent (using the 99% confidence level) or less stringent (90% or 80% confidence level) based on your needs.
The results are presented in three stages. First, the chi-squared value is presented. For a critical value based on a confidence level other than 80%, 90%, 95%, or 99%, refer to a chi-square table. Second, the critical value for this test is presented based on the significance level selected. Finally, a simple "yes" or "no" indicates if these two groups are significantly different based on the information provided.
