I am New to the SPC, so I know something about "Sigma" Value. But Calculating sigma is lengthy, so anybody can suggest me if there any another shortcut methode or formula. please tell me in brief.:) I may be stating the very obvious, but any calculator with some statistical functions can do that for you. Note that the standard deviation (sigma) can be calculated for a sample and a population. I hope that's what your asking. If not, let us know. Stijloor.
