I have performed a McNemar test for paired binomial variables in SPSS to see if the success rate(score 1) differs between the two conditions (the two variables: the before and after treatment variables). When I run the McNemar test using the cross-tabs function in SPSS it does not report a test-value, only the Exact Sig (2-sided), which in my case is .000, so significant. It also notes that the binomial distribution is used to determine this.
However, when I run the McNemar test using the nonparametrics tests --> related samples function, the Chi-Square is also reported, 58.061, AsympSig .000. In the end the most important thing is that there is a significant change from before to after the treatment. However, I am wondering if I should also report the Chi-Square value. The first p-value is based on the binomial distribution so I guess reporting the Chi-Square does not make sense. On the other hand, why not just report the Chi-Square and the accompanying p-value of the second method?
I hope someone has some insight on this.Thanks!
