The results were significant (χ2(3)=8.44,p<.05), suggesting that people did not select suits purely at random. This is pretty straightforward, and hopefully it seems pretty unremarkable.
WebApr 28, 2016 · In that context, you don't assess the fitted r value, you convert that r -score into a test statistic that is distributed as t.
