New Publication: The Importance of a Proper SPC Subgroup Sampling Technique

Article Revised: March 27, 2019

Incorrect subgroup sampling technique selection has become worse in the modern computing age – perhaps because most practitioners try to “fit” their data into the GUI template of the major statistical software packages.

This paper will discuss proper SPC subgroup sampling techniques and illustrate the principles of proper subgroup sampling selection from a practitioner’s perspective.
