Data without a scale for comparison is no use at all

In principle, each analysis is a comparison, because only classification in context provides useful conclusions.

What can a picture of Saturn tell us if we don’t have a relative idea of its size? How big is it? Bigger or smaller than…? What kind of scale of comparison would be helpful to us? The Earth? Now, how big might Saturn be in comparison to the Earth? Bigger? A lot bigger?

Freakonomics

The unconventional Business Professor Stephen D. Levitt shows how an economic framework coupled with unorthodox thinking can provide new answers to questions of data analysis. The fact that his answers aren’t always “politically correct” only increases the enjoyment for critical readers, but also means Levitt receives numerous threatening letters. His thesis that there is a connection between the legalization of abortion in the USA in 1973 and the sinking crime rate 21 years later, has provoked particularly controversial reactions.

All in all, can’t-miss reading for all those who mistrust all-too-simple explanations.
