Cohen's kappa coefficient (symbol κ, lowercase Greek kappa) is a statistic used to measure inter-rater reliability for qualitative or categorical data. It is generally thought to be a more robust measure than simple percent agreement calculation, as κ incorporates the possibility of the agreement occurring by chance. There is controversy surrounding…
The analysis highlights History, Related statistics and Definition as prominent areas in the source structure around Cohen's kappa.
Source areas are shown by the number of related topics found in each part of the analysis. Use smaller areas too: they can reveal specialized angles and content gaps.
