How to calculate cpk for attribute data
Web9 apr. 2024 · 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). If Cp value is equal to Cpk value, then the process is operating at borderline conditions. WebCapability index: Cpk Estimate: 1.33 Relative error: 10.0% Confidence level: 95.0% The required sample size is 154. The StatAdvisor To be 95.0% confident that the true value of Cpk is no less than 10.0% below the estimated value, the required sample size is 154 if the estimate equals 1.33.
