To improve the use of kappa statistics: - Use Weighted Kappa: For ordinal data, weighted kappa can be more informative as it considers the degree of disagreement. - Report Confidence Intervals: Providing confidence intervals for kappa can give a better understanding of the precision of the agreement. - Consider Multiple Raters: Extending kappa to multiple raters (Fleiss' kappa) can be useful in studies involving more than two raters.
