Best ResponseYou've already chosen the best response.0the general rule is to use not too few and not too many intervals. so 4 is okay me.

Best ResponseYou've already chosen the best response.0just make sure that the low interval must include 110 and the high interval must include 124. also, equal intervals are preferred over unequal intervals, particularly to ratio type of data.
