Nicely explained

[@vocation8032]

Please explain how you calculate A2...

[@wikakawina1915]

You don't, these have been calculated and are usually provided alongside the question

[@aboalinoona9211]

hi sir thanks for this nice presentation please i need to know how can i use regression with capability i mean what dos y mean thanks

[@EdDansereau]

Hi, I am unsure of your question. The mean is the average of the numbers, called X bar (X with one line over the top). X bar bar (X with two lines over the top) is the average of averages). So you average each group of measurements and then average the sum of all measurements. I hope that helps.

[@nikhiltavase1990]

also the d4 column And is it already given in the sum we get?

[@theeasyengineering]

Very helpful...

[@charlie50201]

Very well described Ed. Makes all the other sound like they just want to hear themselves talk

[@EdDansereau]

Thank you, enjoy

[@andrewisaacibarra3710]

Why for A2 did you choose 5 legs for each sample and not any other number?

[@EdDansereau]

Hi Andrew, I am not following your question. Would you mind expanding the question a bit so that I understand? Thanks, Ed

[@nikhiltavase1990]

can u please explain how did you get the D3 column values ? that is the only thing i guess that you haven't explained rest everything is crystal clear after your explanation

[@bahadirezici]

+Nikhil Tavase that colums (d3 and d4) have already calculated and accepted so you don't have to calculate them.Just read it

[@EdDansereau]

+Nikhil Tavase Bahadir is correct, just use the chart that has the values calculated value. "N" is the number of opportunities per each measurement. For example, if you measured 5 items (5 opportunities) each hour during an eight hour shift, your "n" would be 5.

[@ipekuzun9482]

this question all form where find ?

[@danman281]

Great explanation. I added better explanation to my PE reference manual

[@EdDansereau]

Thanks for watching

[@Whiskyreviews]

what if the value of a certain mean is lower than the lower control limit?

[@wikakawina1915]

Means it's not conforming and you have to correct that

[@mannytvz]

Ahh. Why can’t my professor be this organized. I can’t read shit from her .. thank you!
