WebOct 18, 2024 · Let’s break down Cohen’s kappa. What Is Cohen’s Kappa? Cohen’s kappa is a quantitative measure of reliability for two raters that are rating the same thing, correcting for how often the raters may agree … Cohen's kappa coefficient (κ, lowercase Greek kappa) is a statistic that is used to measure inter-rater reliability (and also intra-rater reliability) for qualitative (categorical) items. It is generally thought to be a more robust measure than simple percent agreement calculation, as κ takes into account the … See more The first mention of a kappa-like statistic is attributed to Galton in 1892.
