OK so i have a question.
the new version of minitab allows you to input the specification limits for GR&R studies so you can calculate the PT ration(GR&R tolerance) no problems here.
However if you have a single sided spec i have always been taught that you cannot calculate a PT Ratio. But Version 15 of minitab spits out a PT ratio if you put in a single sided spec.
Can anyone explain why this is and how minitab is calculating it?????
