which variation considered in MSAHi Mark,
I am new with using JMP. Just for clarification, what is the difference between Gauge R&R value in variance components for Gauge R&R results and the %Gauge R&R=100*(RR/TV) in Gauge R&R results. Which one is considered for MSA.
WindowsRe: which variation considered in MSAWhen you have the report window open, select "?" tool from toolbar and highlight the part you are interested in and click it

this will open help page for you Quality and Process Methods > Variability Gauge Charts > Variability Gauge Platform Options > Gauge R&R Option which might help you answer your questions (you might have to browse other pages in Help, but this is a good start usually).
