Abstract Cohen's (Educ Psychol Meth. 1960; 23: 37–40) kappa statistic has been criticized
recently for providing low chance-corrected coefficients (< 0.40) despite high levels of …

In the previous issue, we looked at Cohen's kappa (κ), a statistic that is very often used to
measure agreement between raters for both nominal and ordinal ratings. An important …

The kappa coefficient, sometimes known as Cohen's kappa after its originator, is a
nonparametric statistic that assesses the degree of association between categorical …

Researchers comparing diagnostic systems or screening tests frequently need to compare
