I was reading the MSA 3rd Edition manual, and found that now the K1, K2 and K3 constants used during the long GRR method have been changed to follow the d2 table in Appendix C, page 195. I've few questions.
1. On page 115, Analysis of Reswults - Numerical, it says that K1, is 1/d2, whereby d2 is dependent on the number of trials (m) and number of parts X number of appraisers (g). But for K2, it is dependent on number of appraisers (m) and g=1 (range)...and as for K3, it isdependent on number of parts (m) and g=1 (range)
Now, I'm a bit confused on the usage of m and g here. How do we get the 'range' (g) = 1 for the cases of K2 and K3 ?
Maybe someone can enlighten me of how to use the m and g more efficiently ?
2. In the Appendix C, page 195, Table d2, if the g > 20, it is true that we will use the d2 infinity value, which is right at the bottom of the table ? (second last row) ?
What is the 'cd' value for ?
3. Can anyone help me on the definition of 'degree of freedom' ? Been to some of the website, and still could not grasp the idea. Anyone care to explain it in layman term ?
Thanks a lot !!!!
