Thinking about polls got me thinking about statistics and a good book:
[QUote author=Wikipedia]
"How to Lie with Statistics" is Darrell Huff's perennially popular introduction to statistics for the general reader. Written in 1954, it is a brief, breezy, illustrated volume outlining common errors, both intentional and unintentional, associated with the interpretation of statistics, and how these errors can lead to inaccurate conclusions.
Over time it has become one of the most widely read statistics books in history, with over one and a half million copies sold in the English-language edition.[1] It has also been widely translated.
Themes of the book include "Correlation does not imply causation" and "Using Random Sampling". It also shows how statistical graphs can be used to distort reality:
1) By truncating the bottom of a line or bar chart, one makes differences seem larger than they are
2) By representing one-dimensional quantities on a pictogram by two- or three-dimensional objects to compare their sizes, one makes the reader forget that the images don't scale the same way the quantities do. Two rows of small images would give a better idea than one small and one big one. [/quote]
