I wish I would have found this video first in my research. Very thorough explanation with visual example that made this digestible for my brain. THANK YOU.

Really helpful - thank you very much. I’ve been looking online for hours and this explained it better than anything.

The major difference between Pp, Cp, Cpk and Ppk is the way we calculate standard deviation that is sigma where Cpk uses rbar/d2, a constant. And the the one you are calculating is Ppk not Cpk.

Thanks, but why you didn't use R/D2 formula to calculate the Cpk, from your video, you use std so, it is PPK, not Cpk

Hi, can you show how do you plot UCL and LCL on a histogram with bell curve. What type of calculation do you do to get them appear on the graph?

[darladue]

How did you calculate the USL and LSL?

[nicholaslubinski]

Now take your data and plug it into minitab and you will notice this is PPK not CPK.

[EC]

What if the USL-mu and mu-LSL answers are the same?

[nazifnazli]

To calculate cp value. Why we need to divide with 6? What is 6 stand for?
