Can Cohen’s kappa be used for more than 2 raters?
Cohen’s kappa is a measure of the agreement between two raters, where agreement due to chance is factored out. We now extend Cohen’s kappa to the case where the number of raters can be more than two. As for Cohen’s kappa no weighting is used and the categories are considered to be unordered.
Can SPSS calculate Fleiss kappa?
Unfortunately, FLEISS KAPPA is not a built-in procedure in SPSS Statistics, so you need to first download this program as an “extension” using the Extension Hub in SPSS Statistics. You can then run the FLEISS KAPPA procedure using SPSS Statistics.
How do you do weighted kappa?

What is weighted kappa?

How do you test for inter rater reliability in SPSS?

What is good interrater reliability?
There are a number of statistics that have been used to measure interrater and intrarater reliability….Table 3.
| Value of Kappa | Level of Agreement | % of Data that are Reliable |
|---|---|---|
| .60–.79 | Moderate | 35–63% |
