What is the value of Sigma?

A sigma value is a description of how far a sample or point of data is away from its mean, expressed in standard deviations usually with the Greek letter σ or lower case s. A data point with a higher sigma value will have a higher standard deviation, meaning it is further away from the mean.

What is CPK formula?

A proper centered process will have Cp = Cpk. An estimate for Cpk = Cp(1-k). Since the max value for k is 1.0, so the value for Cpk will always be less or equal to Cp. Input is required from the customer regarding the lower specification limit (LSL) and the upper specification limit (USL).
