I'm not real familiar with Kappa analysis. We are comparing the agreement between two databases on cancer diagnosis and we have some patients in both and some in one but not the other. However there will never be the case that a patient will be in niether (at least to our knowledge). Is it appropriate to use Kappa analysis in this case?
ANOVA, or Analysis Of Variance, is used to compare the averages or means of two or more populations to better understand how they differ. Watch this tutorial for more.
