From Wikipedia, the free encyclopedia

isn't it binSize = 2 * IQR / N^(1/3) ??

[edit] wrong formula

The formula as stated doesn't give anything remotely correct. Looking around on the web a formula that looks right and actually seems to work in my tests is:

(N^1/3 * range)/(2 * IQR)

Where range is the range of the data.
