IR chart 4 sigma control limits

Jun 6, 2018 05:39 AM (5589 views)

Hi,

 

When we make a IR control chart the UCL and LCL are based on 'mean + 3 sigma' limits. Is there anyway to increase the limits to 'mean + 4 sigma'?

 

thanks

Hello,

 

When you are setting up your control chart in the dialog box you can specify the "Ksigma" in the Parameters box in the lower left corner.
