Don't wait to buy software, control charts make money!! Here is a video to show you how to complete and X Bar R chart by hand...Great when you're perfecting your 6 sigma knowledge! #6 Sigma #Lean Six Sigma #Six Sigma
I can't find a template for a hand-written x-bar r chart either. I thought that this would be very easy to find. Would you share yours with me? Great videos. Excellent topics.
Hi Paul, have a doubt. If the operator adds one more subgroup data after the 24 th point, will the centerline change? So how to show the change in centerline on paper? It won't be a straight line throughout right? Can you check and let me know? As always, great topics and great explanation by you. Thanks.
Hi Sadiq - The chart is fixed, no re-calculation is done. The data points are plotted looking for un-usual patterns....compared the the original centreline and limits.
Vignes - Thanks for the comment, if you like my video's please take a look at my book 'dink tea and read the paper' on LULU.COM. I think there is discount currently....
