How cpk is calculated

WebThe formula for Cpk is: Cpk = min ( (USL - average)/3standard deviation, (average - LSL)/3standard deviation) where USL is the upper specification limit (1.53 liters), LSL is the lower specification limit (1.48 liters), and the average and standard deviation are calculated from the data provided. Using the formula, the Cpk value for this ... WebThe procedure is that you measure the distance from the mean value (highest point on the hump) to the point where the curve changes direction and starts to swing outward. This distance constitutes one standard …
