If you're using the set of integers, then [1,9) is equivalent to [1,8]; and that would have a different answer from 5 for "what the center is"; so, it does affect the answer.
... I was using that nomenclature for the short hand of "inclusive/exclusive". 1 to 9 exclusive is 1 to 8 in the integer set. Sorry for the lack of clarity. Perhaps now we can get to my original point?
