This is the followup data from the experiment analyzed in Culp, Ryan, Chen, and Hamada (2018). These data were first presented and described in de Mast and van Wieringen (2010). Thirty parts were rated on a 4-point ordinal scale of 1-4 by each of 3 raters in a balanced design of 2 repetitions per combination of part and rater.
