Analyzing a Gage R&R in Minitab (ANOVA Method)

In this lesson, we illustrate the analysis of Gage R&R data for a standard crossed study using the ANOVA method.   We review the statistical output and focus on the ANOVA table interpretation.  In addition to the standard graphical output, an individual value plot showing all the raw data is presented as a good practice.  We end with a discussion of reasons for poor repeatability and poor reproducibility.
