I have a dataset:
5, 10, 11, 13, 15, 35, 50 ,55, 72, 92, 204, 215
The formula for binning into equal-widths is this (as far as I know) $$width = (max - min) / N$$
I think N is a number that divides the length of the list nicely. So in this case it is 3. Therefore:
width = 70
How do I use that 70 to make the bins?
EDIT: Found the answer. Should I answer my own question or just delete it?
