It's true

Hey Jim, you are awesome. Even after 11 years your videos are still helpful.

THANKYOU SO MUCH!! I had absolutely no idea what the hell I was doing and I still don't and yet I have two complete and complicated looking graphs that fit the description so I won't look like a total idiot to my lecturer. Thanks man!

I've been near tears trying to figure this out with no guidance in my textbook. This has saved me. Thank you very much!

Mr. Grayson is amazing he helped me complete my X Bar / R Bar Assignment and it looks professional and organized. He also showed me how to make models for both of them using line graphs. This made my assignment 100% easier and more precise because I did not manually complete my calculations, excel did them for me.

Jim, I was stuck on a question for my final, this helped me tremendously. Want to thank you and wish you all the best. Life saver.

This wraps up hours of reading and struggling in about 5 minutes that's easily understood. Thank you!

this is absolutely great! I am a 4th year uni student, understood this more than I did from lecturer!!!

Thank you so much for these videos, not only do they help me out with assignments, but they are a really good learning tool, you show the information well and I feel that I really learn a lot from them! Thanks!!

This video was extremely helpful. Thank you for taking the time to put it together and share.

Thank you so much for the explanation on making an x-bar chart and R chart! This really helped me out! :D

If something is greyed out it typically means there is an editing process happening with a cell. Make sure no cells are being edited. Then, highlight a range of cells for the chart and insert | chart | line and it should work.

Thank you so much Jim. I am doing my Master in Project Management and your video has helped me a lot. All the best for you and take care, stay safe. God bless you :D

This is one of the best videos I've ever seen related to the topic. Thank you so much Mr. Jim. ! I admire you !

Can't explain how much you have helped me Mr. If a life, may you be added another year sir

You mate are a diamond, it's currently half 6 in the morning and I've working all night, but you friend, have this day a bit brighter by not making a pointless 40 minute video. Cracking tie as well lad.

Jim thank you you're killing it in 2021

EXTREMELY helpful. Thank you so much!

This is a very well explained example. Saves me a lot of time.

Super helpful! I just completed a final case study thanks to you!

Great and quick explanation. You saved my exam grades, thank you very much!

To make a cell a fixed reference you can highlight the cell in a formula and then use the F4 key to put the $ sign in front of both the row and column reference, for example $C$4, and this would make the cell C4 a fixed reference.

You sir, were so very helpful! Thank you so much for this tutorial!

I just want to say you are a hero! Thank you so much! I was so lost when I was learning this in class... but you saved me! I wish my prof was as good as you at explaning....

Thanks.

We insert $ signs before a column and/or row reference to fix that reference so that when we copy a formula it always refers to that reference cell with the double dollar signs

Thank you for posting this video! I've had a hard time understanding during class and I had to do a search while doing my homework. This helped so much! Really appreciate it.

i love the fax machine sound in background and also the smell of paper being shred

I know this is now 11 years later, but thank you!

Brilliant explanation thank you you really helped me with my assignment.

The plotted statistic is the mean (x -bar). The control limits, typically called 3 sigma control limits, are +/- 3 standard deviations of the statistic, or +/- 3 standard errors in this case from the center line. The limits can be set at any multiple of the "standard deviation" from the center line with the decision trade off of time to detect a shift versus the likelihood of a false alarm.

Thank you for helping me complete my XBar chart.

Thank you very much Mr.Grayson🙏 Very helpful in my studies in 2022🙏Bless you.

Thanks. Glad it was helpful.

thank you for the amazing video

You are the man! Thanks so much!

thank you Mr.Grayson your video helped me in my class of QHSE . thank you very much sir.

Good day sir. Is there a minimum number of samples and observation in order to use the x-bar and r chart? Thank you.

Thank You so much for taking the time to answer me so quickly........You're awesome! .....Then I would chart each time separately?........I'll have to look up "Individual moving Range charts" and how to set that up.......Are there constants involved with ImR charts?............

It is the number of observations (horizontal) for each row .. that will tell us the average of xbar and R (vertical)

thank you so much sir. your video was really really helpful!

Great explanation !! Thanks alot
