Folks,
I do have a problem to do low sample size GRR due to only 2-3 samples available. What I am thinking is that we can do type 1 GRR, but not sure whether this is correct way. If it's correct, and how can we evaluate the variation between the inspectors? Currently I let 3 or X inspectors measure 1 parts individually 20+ times and calculate the Cg/Cgk individually and also conduct the hypothesis test among different inspectors. Is that works?
Thanks.
Best Regards
Steven
