Before following the steps to calculate kappa.
This video demonstrates how to estimate inter rater reliability with cohen s kappa in spss.
Question about weighted kappa and spss extension. This video demonstrates how to estimate inter rater reliability with cohen s kappa in spss. I am working on increasing inter rater reliability for a video coding project and my advisor and i came to the conclusion that a weighted kappa. In research designs where you have two or more raters also known as judges or observers who are responsible for measuring a variable on a categorical scale it is important to determine whether such raters agree.
