If you have attribute data that goes with the value data (such as batch #) this
can be sequenced etc. You can then perform an analysis that seperates them.
Be careful not to assume any distributions, but to let the distributions appear
from the data. After all, your data doesn't care what you think - but to
understand the elements of variation you must not presume.
I've got electronic examples - if you like I'll email them to you. Let me
know.
