Fleiss Kappa Calculator
Medical example dataThe Fleiss Kappa is a value used for interrater reliability. If you want to calculate the Fleiss Kappa with numiqo you only need to select more than two nominal variables that have the same number of values.
If numiqo recognized your data as metric, please change the scale level to nominal so that you can calculate the Fleiss Kappa online.
If you select two ordinal variables, the Cohen's Kappa calculator is used.
