Yes, that is correct. Each kid has a result from each tool. There were 51 total kids tested. My main concern is that these screening tools aren't scored on a numerical scale. It is strictly pass or fail - is that going to have an impact on using the paired t test? Should I be looking at something more nonparametrical?If I get you right, for each kid you have two samples, one for each tool. Both numbers are continuous and you want to compare the tools ? If so, paired t test

Hi mermaidrunner. Welcome to MHB!Yes, that is correct. Each kid has a result from each tool. There were 51 total kids tested.

That sounds like a two-proportion z-test, pooled for $H_0\colon p_1=p_2$.

See for instance this wiki page.

I had some trouble setting up Mcnemars in spss.. it wasn't looking right . Any suggestions?Hi mermaidrunner. Welcome to MHB!

That sounds like a two-proportion z-test, pooled for $H_0\colon p_1=p_2$.

See for instance this wiki page.

I actually went ahead and ran the 2 proportion z-test (in Minitab). Is that going to be effective? Just trying to cover all my bases before submitting.

Here is a youtube clips showing how to do McNemar's test on SPSS.

McNemar Test - SPSS (part 1) - YouTube

Minitab doesn't support it, but you can download a macro from their website which does it.
