Hi, can anyone give me a push in the right direction withthis question please?
A machine produces items. The quality of each item is rated either 1, 2 or 3.
A second machine does the same.
If I take the average quality rating of 100 items from eachmachine, and I want to test whether the difference between them is significant(i.e. is one machine producing significantly better items than the other?),what is the most appropriate statistical test to use?
Thanks,
Ian.
