Hans Rosling from The Joy of Stats on BBC Four. Another excellent example of data communication. I use it in first year lectures to elicit discussion on the issues with aggregating data, in particular how a summary statistic can hide differences between subgroups. We also talk about how many variables are being plotted. It’s something different for them – it puts what they’re learning in a global context and shows statistics as being more than just calculating means and variances.

Pretty neat, eh?
