I have several performance measures for a product that i have to do capability analysis on. For that purpose i am testing the normality assumption on the dataset. However i am a little confused as to what test to use in Minitab that would be best. Because i am doing capability analysis normality in the tails is important which is what the AD test emphasizes on however the common notion is that AD test doesn't work too well for dataset > 1000. If i look at the p-value it tends to reject all the distributions. Any suggestions on what test would be best to use??
Thanks in advance for any help in answering my question.
