Common Gage RR Metrics

Although we will mostly apply these in the next module, in Lesson 5 we define the common metrics uses to judge the results of a Gage R&R study.  These include, % Tolerance RR, % Process RR, % Process RR based on variances, and ndc.  We also discuss the questions that these metrics are intended to answer.  Finally, we provide guidelines for determining the acceptability of the metrics.
