That is so nice. Within 10 minutes, had an idea about various Control Charts. Thank you.

I have been in quality for over 30 years, and in my lifetime, only a few people have been able to explain it as nicely as you did.

Every time I mentored my colleagues, I tried to explain Control Chart methodology similarly to how you explained it.

Kudos!

Hello, nice overvieuw video.
In the example of the XBarChart you take 25 data points (each containing 5 samples a day) so in fact the UCL/LCL are based on 5x 25 samples = 125 samples Yes?

But suppose in a laboratory certain analysis runs on one daily run with control standards/samples
... so 1 datapoint/day

1. How many samples (days) would you take to calculate the Mean, StdDev and UCL/LCL ?
Should you take 30 as a minimum (30 is the border between T-distr. vs. Normal distr.) or do you take another statistical limit ?

2. When, in time, there is a clear indication of a shift of the mean (up or down...) how to react in a correct way for recalculation of Mean, StdDev, UCL/LCL etc... ?
