I have this values in my spreedsheet
-3, -1, 4, 1, 3, -2, -2, 3, -1, 5
and I take the mean 0,7 SD 2,5 and CV 357,14

in another hand I have other values:
6, 5, 5, 8, 6, 7, 8, 6, 8, 6
M: 6,5 SV: 1,0 and CV: 15,38.... it's ok, but when I have a mean 0, no matter what value of standard deviation, the CV is going to be infinite.

how can I show this variation, even with a zero-mean?
