Hi all. I was wondering how to calculate Cpk using Rbar/d2 with a subgroup size of n = 1. All of the d2 charts I have list a minimum d2 value set at n = 2. Should we use the Ppk standard deviation or some other value for d2?
Thanks Bev! It sure is great having this forum back again! I hope you have a swell Christmas too. Maybe some day our paths will cross again.
Your Friend,
Brad
