Gage R&R with Other Factors (Expanded Gage R&R)

The last lesson looks at the use of expanded Gage R&R studies to assess other factors in the study (besides part and operator).  These studies may be useful if other factors (such as within part variation) may be inflating the measurement error.  We provide an example where measurement location has a big influence on the results.  Treating the location as another reproducibility component and ultimately categorizing this variation as part variation allows us to isolate the true error coming from the measurement system.
