I am having a terrible time trying to calculate reliability (I guess this would be inter-rater reliability?) for a project. I have been working on it for days trying to use all the various formulas I find and I'm just at a loss.

All I'm trying to do is come up with a reliability coefficient for the 34 client scores below. As I understand it, the reliability should be pretty close to the average (which for the scores below is 83). But I keep coming up with weird numbers like 20. Any help at all would be greatly appreciated!

B 80

E 86
