Measurement of the extent to which data collectors (raters) assign the same score to the same variable is called interrater reliability. Some of the various statistics are; joint-probability of agreement, Cohen's kappa and the related Fleiss' kappa , inter-rater correlation, and intra-class correlation. First, the kappa statistic should always be compared with an accompanied confusion matrix if possible to obtain the most accurate interpretation. A comparison of Cohen’s kappa and Gwet’s AC1 when calculating inter-rater reliability coefficients: a study conducted with personality disorder samples. However, they use different methods to calculate ratios (and account for chance), so should not be directly compared. the interrater reliability of the FMS.
