The formula for breaking a sequence of values into groups of equal ranges is:
max - min / number of categories
I would like to know why is it necessary to subtract the maximum value from the minimum value?
Thanks

That captures all of your data. If it was smaller range it wouldn't, and if it was bigger, who cares about the extra stuff where your data doesn't exist?
