Talk:Freedman–Diaconis rule

isn't it binSize = 2 * IQR / N^(1/3) ?? —Preceding unsigned comment added by LN29 (talk • contribs)

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. —Preceding unsigned comment added by 64.157.93.210 (talk • contribs)

The formula listed is the formula found in the paper. Could you maybe be thinking of the number of bins rather than the bin size? (Lucas(CA) (talk) 19:07, 5 October 2016 (UTC))
