How to figure out numbers of buckets

Rough way to determine number of buckets/classes to split a dataset into, for frequency distribution analysis / histograms:

2ⁿ⁻¹ < α < 2ⁿ

where α is the size of the dataset.

In other words, find a power of 2 that yields a number just larger than the size of your dataset. Decrementing this power would yield a number smaller.

Why Functional Programming Matters

###John Hughes, Institutionen f ̈or Datavetenskap, Chalmers Tekniska H ̈ogskola, 41296 G ̈oteborg, SWEDEN. rjmh@cs.chalmers.se

This paper dates from 1984, and circulated as a Chalmers memo for many years. Slightly revised versions appeared in 1989 and 1990 as [Hug90] and [Hug89]. This version is based on the original Chalmers memo nroff source, lightly edited for LaTeX and to bring it closer to the published versions, and with one or two errors corrected. Please excuse the slightly old-fashioned type-setting, and the fact that the examples are not in Haskell!

##Abstract

As software becomes more and more complex, it is more and more important to structure it well. Well-structured software is easy to write, easy to debug, and provides a collection of modules that can be re-used to reduce future programming costs. Conventional languages place conceptual limits on the way problems can be modularised. Functional languages push those limits back. In this paper we show that t
