# Can One Use Cohen’s Kappa to Examine Disagreement?

@inproceedings{Eye2005CanOU, title={Can One Use Cohen’s Kappa to Examine Disagreement?}, author={Alexander von Eye and Maxine von Eye}, year={2005} }

Abstract. This research discusses the use of Cohen’s κ (kappa), Brennan and Prediger’s κn, and the coefficient of raw agreement for the examination of disagreement. Three scenarios are considered. The first involves all disagreement cells in a rater × rater cross-tabulation. The second involves one of the triangles of disagreement cells. The third involves the cells that indicate disagreement by one (ordinal) scale unit. For each of these three scenarios, coefficients of disagreement in the…
