Thank you, this is very helpful for me. I was asked to recreate an X bar S chart in Tableau and most resources I could find online were going over my head because i didn't come from a STEM background. This finally helped the concepts click for me. Thank you!
This was explained very well as a Senior Engineer I have done several calculations like this by hand; as I always want to be able to explain to my manufacturing personnel what the application of the problem is telling me, I find doing it manually really keeps one sharp. Again Kudos to your thorough explanation.
In practice, if you were to use n instead of n-1 in the denominator, you would underestimate the population standard deviation. Bessel's correction helps ensure that the sample standard deviation is an unbiased and more accurate estimate of the population standard deviation, especially for small samples. For large sample sizes, the difference between using n and n-1 becomes negligible.

Wow! This was really straight forward and easy to understand. A huge help. Thanks.
Very Useful Information! Thanks for sharing.
good explanation,thanks
Thanks for your explanation, but! According to the book, X bar has 10 subgroup and more. However, R bar has 9 subgroup and less.
thanks for saving me :)
Very resourceful.
Can you please upload An table!
Thank you mam
Thank you
Life Saver HAHAHA ! or future saver hahaha
which book did you use it for equation?
When you were calculating S chart how did u get the lower and the upper limits value
what if we want to calculate xbar and s chart with 2 sigma and 1 sigma?
Ma'am plz make a video for attribute data chart as (u chart,p chart.np chart,p chart.
What about if my subgroup size varies from n=8 to n=35?
hi thanks for this nice presentation please i need to know how can i
use regression with capability i mean what dos y mean thanks
how do you calculate S value? I tried to use the formula that you provided but when I calculate the result are not the same
Sure the results are not the same given other values
Mam please upload video on msa gauge r and r
Why did you divide by 3 and not 4?
form the formular si = root Σ( xi - xbar )power2 divide by n-1
I think is must divide of 4. Because the total m
Yes it should be decided by n not n-1

It should be 4 because the sample size is 5 so n-1 4
I like you
From where are you getting the A_n from?
Table factor
Thanks mam
