Statistical Alchemy

I am posting a few new resources. I whimsically refer to them as my ‘memoirs’ or ‘what I have learned from 35 years in the quality profession'. The current series has my rants regarding the statistical alchemy that I believe has ruined the Quality Profession. I have posted 3 resources so far. The first is an introduction to what statistical alchemy is, the second concerns RPNs and the third is about the abomination of process capability indexes. I am interested in your opinions – even those that are diametrically opposed to mine. I look forward to a spirited discussion.
