You really brooked this down to a level where I could see how it all worked and came together. Thank you.
Man. you are the best when it come to explaining things. Thank you very much
Thanks!!!!
I enjoy teaching, and I especially enjoy helping people like you learn and grow!
You've enabled my brain to understand the logic without memorizing ❤️
I am prepping for my first Quality Engineer job position. Your videos have been super helpful and clear! Really appreciate the help!
Hey Nicolas, thanks for the feedback, I'm glad you're enjoying the videos!!!
I have to mention that your videos really explains how to get the Z value thanks
Awesome, thanks Karla!!
Perfectly explained! Thanks a billion.
Thanks!
really appreciate your efforts! thanks so much!
Glad you like them!
Thanks for your detailed video clip!!
You're welcome Arul!
Excellent. Excellent. Excellent.
awesome presentation
Thanks Jagdish, i appreciate the compliment!
APPRECIATE IT
Best explained. 😀
Thanks Garima!!
Thank you sir
Thanks great refresh any six sigma book you recommend for someone who wants to get green belt certification
Lean Six Sigma Pocket Toolbox by Michael George is a good cost effective start. Doesn't go too deep but gives a decent overview and reasonable detail on on a lot of topics.
if you have a narrow range of tolerance and if the part dimensions are on the maximum side of specificaiton how could you maintain the cpk value greater than 2
Hey there! Okay, so the first thing I would do is to try and move the dimension away from the maximum side of the specification. Centering up your dimension in between your tolerances will improve capability, and then the next thing I would do is to reduce the natural process variation for that component. To be honest, a CPK greater than 2, is hard to achieve, so best of luck!
Hello Andy, thanks for sharing, i would like if you can explain to us if on the same question (6:24) the question is what percentage of test takers gets a score more than 73 and 84?
Hey Felix! Do you mean between 73 and 84?
A score greater than 73 would be 93.3%.
A score greater than 84% would be 37.1%
thanks @@CQEAcademy

Isn't it 6 positive st. dev on right and 6 negative on left rather than 3 left and right?
Hey There, can you clarify your question?
Is there a timestamp in the video that you're thinking about?
@@andyrobertson566 At 8:17, when we are talking about +/- std dev, I understand, in actual it is 6 S.D on right and 6 on left, not 3 on either side.
Hey @@leoeveee , I think you might be confusing probability with six sigma.
So when you achieve a six sigma process, you capture +/- 6standard deviations on either side of the mean, and this captures like 99.999997% of the distribution.
In that example at 8:17, I'm simply using the normal probability tables at +/- 3 standard deviations, which captures 99.7% of the distribution.
@@andyrobertson566 Thanks for explaining. Love your videos!
i like ur video and presenting but I do not get the smooth flow of information that I got fron ur video about reliability
Hey There!!!
That's honestly some fair and constructive feedback! This is a relatively older video of mine, and over time I"ve improved my delivery when training, and at some point I should probably re-shoot these lectures so that they better reflect my training skills
@@CQEAcademy really you are prefect trainer, and it will be sooo helpful if you make a content from the beginning, the history of the statistics and the need for each distribution and probability method, because you are one of those who have an amazing mind to speak up about these, not just mentioned the method with examples without how
@@MS-be9wv Thanks so much, I appreciate that feedback, and honestly, that's exactly what my course, The CQE Master Class, (cqeacademy.teachable.com/p/cqe-certification-in-6-months) is all about!
I cover all of the aspects of the entire CQE body of knowledge from start to finish!
@@MS-be9wv Thanks so much for that awesome feedback, and to be honest, that's what my course, The CQE Master Class (cqeacademy.teachable.com/p/cqe-certification-in-6-months), is all about. We cover every single topic in the CQE Body of knowledge from start to finish!
