WebApr 13, 2024 · How to transform non-normal data. The second step to transform non-normal data for SPC is to apply a mathematical function to the data that changes its shape and makes it more normal. There are ... WebEvaluating the Relationship Between Cp and Cpk Before relying on the Cp and Cpk values: Verify that process variability is stable, i.e. no out-of-control patterns on the control charts. Review individual data values on a histogram chart to verify that the distribution is normal (or close to normal). Verify that engineering tolerances are known. ksl classifieds used atv and four wheelers
