Strength Of Agreement

Statistically very significant z-tests indicate that we have the zero hypothesis, that the evaluations are independent (i.e. kappa = 0) and accept the alternative that an agreement is better than one might hope by chance. Don`t put too much emphasis on the Kappa statistics test, it makes a lot of assumptions and falls into errors with small numbers. Cohen`s Kappa measures the concordance between two evaluators who divide each of the N elements into mutually excluded C categories. The definition of κ {textstyle kappa } is as follows: Journal: A proposal for strictt-of-agreement criteria for Lin`s concordance correlation cohen`s kappa (Cohen 1960) which avoids the problems described above by adapting the observed proportional concordance to take into account the amount of concordance that would be expected by chance. Fleiss only indicates the standard kappa error to test the zero hypothesis «No concordance». To appreciate kappa according to the fleiss method, we do not know any relationship between observers for different subjects. This method does not take into account the weighting of disagreements and is therefore appropriate for the data in Table 20.8. We don`t have the details…
