One what? Any statistic that depends on the units used seems rather
arbitrary to me. If I compute the range of weights of a group of people
(in kilograms) I ought to get the same actual *weight* as an American
using pounds or a Brit using stones.
Suppose I have three meter sticks - are you telling us that the range
of their lengths is a little over one meter?
I'm afraid I vote with your students.
