SubGroupSize1- Calculating StDev(within), StDev(Overall), Cpk,Ppk in Excel-Within Standard Deviation

When data is collected in subgroups, calculating variation is straightforward, as we can easily compute it within each subgroup using metrics like subgroup range or subgroup standard deviation.
However, when data isn't grouped (i.e., the subgroup size is 1), determining within-subgroup standard deviation becomes less intuitive. How do we calculate variation within subgroups when there's just one data point per subgroup? What impact does this have on Cpk? This video aims to demystify the calculation of within-subgroup variation and its implications for Cpk when dealing with a subgroup size of 1

Thank you so much, im dying for searching stdev(within) calculation

Thank you so so much

Thank you very much, I had doubt in Overall standard deviation and standard deviation within. It's get cleared. 😊

Glad to hear that

Hey, great video, but how did you make the graph? I searched for the "Stat" Tab in Excel but I can't find it, how can I have this tab?

Hi I have doubt could you please explain what data I need to calculate cpk & ppk . Example if we have 49points measured do I need to take individual value or average value? Please explain

Hi. Thanks for the video. I just need some clarification. When I follow your step, I found std dev overall & within vs with minitab were not same. Can you help on this?
