Rock 'n Poll by Maarten Lambrechts et al

Rock 'n Poll is polls explained with interactive graphics.

Politicians as well as journalists take political polls very seriously. Losses and gains of a few percentage points are overly analysed and commented on.

This interactive explanation shows you why polling results should be taken with a grain of salt. In a lot of cases decimals will prove to be meaningless and changes of less than 2 percentage points shouldn't be subject to much analysis.

The statistical basics of polling are explained visually, interactively and playfully, without using a single formula.
