Dear experts,
I am trying to provide a SW tool oriented to MSA and I have a simple questions:
1) Does I-Chart (individual Observation chart) need always to be associated with MR Chart? I need MR chart in order to calculate I Chart control limits UCL and LCL don't I? Does it make sense to show only I-Chart witl UCL and LCL = Mean +/- 3 sigma?
2) Same question for Xbar-chart: does it need alway R-Chart to be associated with?
Thank you for supporting a newbie
