I am taking electrical measurements, 7 per product. I would like to be able to first characterize what 'normal' behaviour is; i.e. for product that passes, what is a normal range, etc. Each of the 7 measurements relates to a different position on the product and we expect a difference on some versus the others. We 'd like to understand this, too. Also, when we have significant quantities of failures w/in a small population, we'd like to analyze the remaining product statistically versus 'normal' behaviour to determine that even though it passed, is it what we'd normally expect to see or is is significantly different and we should be concerned?? Thanks!!
