Please Help! How Total Variation is calculated - Minitab Gage Question
I am new to Minitab so please excuse the basic nature of this question. I am trying to understand how Total Variation is calculated. Shouldn't Total Variation simply be Total SS divided by total df? In the R&R Loan example provided to me, Total SS was 1765.79 with 89 df. Total Variation came out to be 25.1465. How was this calculated?

Hi Wes2007,

We have a whole board devoted to Minitab Questions - so I moved your question here and retitled your thread. You may want to look around a little and see if your question has been addressed before.

Sorry I can't help you with your specific request.
