As i could see , p chart & u chart has been explained , but i could not find the c & Np chart explnation any where . Do we have the same however.

[@learnandapply]

The only difference between charts is with fixed and variable sample size. Both are also get cover in in p and u chart.

[@malakafernando1410]

[@arihantsinghi9686]

Sir.. The subject was very well explained.. I wanted to know what application do you use for making such videos.. I, myself being a tutor of A level mathematics, wanted to make such innovative videos for better understanding of the students. Would it be a problem if you tell me that??

[@learnandapply]

[@atulkumar3744]

For samples collected on same day but at irregular intervals and from different locations does it fall in subgroup sample or no subgroup sample?

[@learnandapply]

No, it's not the subgroup. Thank you for your valuable comments.

[@gggeetss]

very well expalined. Kindly tell me how to develop xbar s chart for preassessment, PDSA 1, 2, 3, 4 in one chart and how to interpret them all together

[@learnandapply]

+Geetanjli Kalyan First of all, thank you for your valuable comments Geetanjli. I think from the video Xbar-S chart must be clear to you. We can draw Xbar-S chart when data is continuous, collected in subgroups and subgroup size is more than 8. Now, as you had asked for Pre-assessment and PDSA (Plan-Do-Study-Act) along with this control chart, it will be having 3 phases of the same control chart. 1st phase, we can called it as a "Baseline data". In this phase, we draw the Xbar-S chart, we can refer it as a "Pre-assessment". 2nd phase is about "Post intervention data". In this phase, which indicates effectiveness measurement of actions we had taken by following Plan-Do-Study-Act or in other words, Study the impact and then plan further actions. This will continued till we get the desired results. And the 3rd phase is about "Continuous monitoring" to ensure presence of assignable cause immediately and correct it.

[@learnandapply]

+LEARN & APPLY I think, I have answered your questions. Let me know your feedback. And thank you again for your such an important query as well as support to my channel.

Please show us how to create the Xbar-R and Xbar-S chart using Microsoft Exel!

[@learnandapply]

Thank you so much for your valuable comments. I will do it in my future videos, once the current topic is covered.

[@thesonshinestate]

I was under the impression that XBar-R charts were for constant subgroup sizes between 2&10. Is this not correct? Is this a recent change in Lean? please advise. My current course material has that range listed.

[@learnandapply]

Thank you for your valuable comments. You can use Xbar-R charts for subgroup size up to 8 and use of Xbar-s chart will be more accurate for subgroup size more than 8. Using Xbar-R chart for subgroup size 9 or 10 won't be wrong, but Xbar-s chart will be more accurate, logic is same as that of difference in Range and Standard deviation...

[@learnandapply]

Please let me know if you need any further details...
