SPC Charts Online
Post any comments you might have regarding the site.
I tried Individual-Range Chart – 2 (Interactive)
input : 10.1,10.3,10.9,10.4,10.8,9.8,10.3,9.9,10.3,10.2
Is this correct?
The libraries on this site haven’t been update for quite a while. The correct answer should be 0.46. We have updated the library to fix this error in the IR Range calculation.
