Yes as far as I can tell.

If it was to be between 0 and 1 then it would be in decimal form.

Using the fact that the Standard Deviation^2 = Variance.

multiplying a decimal number by itself will end up making it less than its original value.

Not really conclusive proof at all. - July 13th 2008, 02:14 PMPlato

I figured as much since the variance is the square of the SD... its just strange to picture the SD being greater than the variance.
