I have always calculated McNemar's test statistic, with M=(b-c)^2/(b+c). Now a professor hands me a different formula, M = (b-c)/sqrt(b+c).

If anyone has any insight, I would appreciate it!

you will want to get a result regarding degrees of freedom. and that is determined by chi-squared, which is calculated by the first formula. your prof provided you with the calculation for chi, you will need to square it, I suppose...I for myself calculate with your formula.

Thanks very much!

Actually, it's not my prof. It's a prof for whom I am supposed to be writing test questions. After looking around the internet I decided to use my formula, even though it's not the one she's going to give the kids on their formula sheet. I think mine is right.

If she wants me to redo them, I will redo them.
