I attended your Statistics for the Non-Statistician seminar back on September 22-23 with a couple of coworkers. We’re now trying to apply some of what we learned and are stubbing our toes a bit. What we’d like to do is compare QC data from an “ideal” lot of product to data from each subsequent lot to determine whether the two lots are significantly different from one another. We would use the result of the test to determine pass/fail status of each new lot.
Can you recommend a test or sequence of tests that would best suit our needs? For what it’s worth, each lot consists of about 3000 units and we’re accustomed to using Excel not Minitab (don’t own a license).
We have received a statistical review of our paper submitted to the Cardiovascular Interventions, and are looking for an expert like you to help us with answers. Please let me know if you would be interested to help.
