I am doing a reliability study during which we had 2 individuals take 6 different measurements using a custom tool. Each of the 6 measurements was repeated 10 times. Now I would like to see if each person was consistent time after time (10 trials) among each of the 6 measures. I would also like to see how consistent the two were between each other. What is the best way for doing this? Any suggestions would be appreciated.

Thank you very much in advance!
