Lastly, the formula for Cohen’s Kappa is the probability of agreement take away the probability of random agreement divided by 1 minus the probability of random agreement. Figure 7: Cohen’s Kappa coefficient formula. Great! You are now able to distinguish between reliability and validity, expla...
Cohen's kappa coefficient is a statistical measure of inter-rater reliability. It is generally thought to be a more robust measure than simple percent agreement calculation since k takes into account the agreement occurring by chance. Kappa provides a measure of the degree to which two judges, ...

The Kappa coefficient was used as a measure of agreement between observed and by chance test results. Also the data was compared by using Ms Excel software. Results: By Amsel's composite clinical criterion 145 (58%)were diagnosed to... AARP Singh,VK Sharma - 《Journal of Advance Researches...
Cohen's kappa coefficient is defined and given by the following function − Formula k=p0−pe1−pe=1−1−po1−pek=p0−pe1−pe=1−1−po1−pe Where − p0p0= relative observed agreement among raters. pepe= the hypothetical probability of chance agreement. ...
