Kappa is a measurement of the how much two variables agree with one another. Vassar College gives the example of two judges who “concur in their respective sortings of N items into k mutually exclusive categories.” You can calculate kappa by inputting numbers into a Microsoft Excel spreadsheet. The written formula for kappa is as follows: Kappa = (Observed Agreement - Expected Agreement) / (1 - Expected Agreement) =(A1-B1) Your cell will be replaced with 5. =(1-B1) The cell will display -4. =(C1/D1) Your kappa answer will appear in E1. It is -1.25. Writer Bio
