Hello, I'm validating a questionaire for inter-rater reliability ( two raters) using kappa. I am a masters student, not statistics.
I have an ordinal categorical variable and wish to get one kappa value + percent agreement per category
( I realize weighted kappa may be more appropriate for this variable when not split)
when i split the variable with split file, spss cannot run crosstabs, what is the reason for this, and is there a fix when i want kappa for all agreements within categories?
when i run crosstabs for the ( unsplit) variable i get only one kappa value.
thank you very much for your help!
