Hi all, I just calculated the corrrelation between two of my cmms. my Pearson product moment correlation coefficient value is 0.727. My p value is 0.000. I have rejected the null hypotheses (CL = 95%). With regards to the coefficient (0.727) which indicates the strength of the correlation, are there any industrial standarda or AIAG standards? Is there something like we have in AIAG for GR&R 0 - 10% error - Gage system O.K.; 10% to 30% May be acceptable...?
