The formula for Cohen’s kappa is calculated as: k = (p o – p e) / (1 – p e). where: p o: Relative observed agreement among raters; p e: Hypothetical probability of chance …
WebCohen's kappa statistic is an estimate of the population coefficient: κ = P r [ X = Y] − P r [ X = Y X and Y independent] 1 − P r [ X = Y X and Y independent] Generally, 0 ≤ κ ≤ 1, although negative values do occur on occasion. Cohen's kappa is ideally suited for nominal (non-ordinal) categories. Weighted kappa can be calculated ...

A …
About 50 to 100 different measures of effect size are known. Many effect sizes of different types can be converted to other types, as many estimate the separation of two distributions, so are mathematically related. For example, a correlation coefficient can be converted to a Cohen's d and vice versa. These effect sizes estimate the amount of the variance within an experiment t…
