I have always calculated McNemar's test statistic, with M=(bc)^2/(b+c). Now a professor hands me a different formula, M = (bc)/sqrt(b+c).
If anyone has any insight, I would appreciate it!

Best ResponseYou've already chosen the best response.0Thanks 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.
