Subtract
Subtract 66-21? Is it a good measure of spread as well then?
Range is only a good measure of spread if the data is uniform (equally spaced apart), otherwise range may give a false representation of spread.
For example, there could be 100 people in the office, and 98 of them are aged 30 to 32 and the other 2 are 21 and 66; the spread of the data is actually not much at all. But it seems like a lot if you use range.
