Thank you for the video. I have a question, I am not sure why did you select d2 from five subgroups (2.326) rather than 25 (3.931) as shown in time 7:23 minutes. Thank you

[@QualityExcellenceHub]

5 is subgroup size. 25 is number of subgroups. D2 taken is based on subgroup size. (i.e. number of reading in one subgroup = 5). Hope your doubt is cleared now. Happy Learning ahead.

[@QualityExcellenceHub]

You dont have to calculate. It is a constant and is taken directly from Table given in SPC Manaul by AIAG. Hope it is clear now. Happy Learning ahead.

Overall SD covers overall population and sampke SD is the SD of only the samples which are under study. Hope this clarifies your doubt. Happy Learning ahead.

Can I ask why in the last slide, the bottom process doesn’t have a Cp of 3? The whole process variation fits into the limits 3 times.

[@armandmatossian2081]

So this is for a 3sigma process? Not 6 sigma?

[@QualityExcellenceHub]

Value of xbar and r chart will be in terms of cp and cpk. Relation of cpk vs sixsigma value is as mentioned below Cpk =2 = 6sigma Cpk=1.67 = 5sigma Cpk=1.33 = 4 sigma Cpk=1 = 3 sigma. Hope this helps. Happy Learning ahead.

[@ivlothanna937]

Sir don't mistake me you make Process capability with Xbar R chart data so what is the relation between SPC and Process capability both are same or different
