Hi,
I am doing a research on paint finish. I thought of using R & R concept in my study. The data I have is both Ordinal ( Rank, Non - Normal ) and measurable data. My Questions are :
1) Can we use R & R for Data which has Ordinal data ?
2) Can the PArts be more than 10 , i.e., 15 , 18 or should we stick to the conventional 10 parts.
3) how is number of trials determined ?
I would appreciate if you could give me a lead in this.
Thanks,
Geets
