after 13-ish years later, this video is still helpful, thank you very much!! our professor told us to do this task without teaching us how to do it, and came across this video with the exact same format. thank you again for this VERY helpful video.
Hello, how do you know the 2.66 value, i know there are some constant value charts, but, the chart finish at 25 observations, so how do you take that 2.66 value, do you have any function?? if you have it, can you please pass it , please.
Please correct me if this is wrong. "UCL = CL + 2.66*Moving range", why should we “2.66” here, since we are looking for 3 sigma isn’t that we should use UCL as “CL + 3 *Moving range “. Though it doesn't make much difference here, however when we compute/analyze large data there may be a difference.
Kesava Raju factually, the function of UCL = CL + 3*sigma / square root n Where sigma is MR bar / d2 So, UCL = CL + 3 MR bar/(d2*square root n) d2 is a constant in a spc table d2 is 1,128 ( we use n=2 because n=1 is not exist) And you will find number 2,66 If you want to ask more you can call me at +6285712289529 by wa only
Great video! I was wondering what factors would be used to estimate 1 and 2 standard deviations. I'd like to construct a color-coded banded chart using these values. Also, would it make sense to use this approach to track weight gain/loss and daily blood sugar readings? Thanks for the lesson.

This helped a lot easy to follow and explained very well. Thank you and I hope to view other sessions of yours in the future.
Thank you, my assignment looked so much better because of this video.

This was very helpful for the Healthcare quality class! Thank you soo much!

from where i get the 2.66? is it assumption? forecast? or what exactly??
Kesava Raju factually, the function of UCL = CL + 3*sigma / square root n
Where sigma is MR bar / d2
So, UCL = CL + 3 MR bar/(d2*square root n)
d2 is a constant in a spc table
d2 is 1,128 ( we use n=2 because n=1 is not exist)
And you will find number 2,66

@@agusluqman7278 kenapa pakai subgroup 2? kenapa ga 3 ,4 atau yg lainnya?
Great video and well explained
Great job with this. Very useful.
Thank you so much your vidio helping soo much
Awesome video - thank you so much
Since the average moving range is not a standard deviation, we use 2.66*the average moving range to estimate 3 standard deviations.

Great video. Thank you mate!
Thank you so much!
How would i plot only the most recent (last 30 days) of data?
