However, coders can code `1` (i.e., present) across all 13 variables.

This means that Assumption 1 of Cohen`s Kappa is violated.

What do I do…I would appreciate any help. Thank you.

Assumption #1: The response (e.g., judgement) that is made by your two raters is measured on a nominal scale (i.e., either an ordinalor nominal variable) and the categories need to be mutually exclusive. For example, the two raters could be assessing whether a patient’s mole was “normal” or “suspicious” (i.e., two categories); whether the quality of service provided by a customer service agent was “above average”, “average” or “below average” (i.e., three categories); or whether a person’s activity level should be considered “sedentary”, “low”, “medium” or “high” (i.e., four categories). In addition, the categories being assessed by the two raters should be “mutually exclusive”, which means that no categories overlap (e.g., a rater could only consider a patient’s mole to be normal OR suspicious; the mole cannot be normal and suspicious at the same time).

Thanks in advance for your response, Sytske

Was wondering whether there is any limitation on the number of attributes. I do not have 0 value and it is only 1-15.

Also, I hope I can enter 1-7 attributes for first pair of columns and 1-15 attributes for next pair of columns for the two different variables?

Thanks a lot. This is a great device!

Wish I had come a across your tool before. Thanks for building and sharing it!

most of the variables will be coded as 0 or 1

however 2 of the variables have 3 possible answers coded as 1 or 2 or 3

can these latter 2 variables be tested in the same way?

thanks!
