AgreeStat360/Excel Windows

An Excel-based application for performing advanced statistical analysis of the extent of agreement among multiple raters.  You may compute Chance-corrected Agreement Coefficients (CAC) as well as Intraclass Correlation Coefficients (ICC).

Check the video below showing how to import your own data to AgreeStat 360, before conducting your analysis (for more clarity you could view this video on YouTube).


CAC statistics include Cohen's Kappa, Gwet's AC1/AC2, Krippendorff's alpha and more. ICC statistics on the hand, include various coefficients based on different ANOVA models.

You may also want to get a more comprehensive overview of AgreeStat/360 capabilities.
