The same results for both nonnormal Cpk calculation?

Hi all,


I use Cpk tool (Analyze> Quality and Process> Process capability) and no matter which method I chose for non-normal data (Percentile or Z-score) I get the same result. How come is it possible? The basic ideas behind those two method are different and I guess they should result in diff. answers...






Could you please kindly guide me on this?
