Origins of 5.15 in Gage R&R Calculations
Can someone please remind me where I can find a good text explanation why 5.15 is the "magical" number to multiply the sigma with to account for 99% of the data??? I need to "convince" someone with no statistical knowledge that this is the "right" number!! This person is calculating stuff from a normal distribution curve and is confused!!! Please enlighten us. Thank u all.
