I like to work in the popular scientific field also. Most of my activities are together with Björn Christensen. Here are some:
Weekly Newspaper column "Achtung Statistik":
Every Saturday in the Journal of the sh:z-newspapers (in German, with Björn Christensen, nearly 400 so far).
Regular column "Angezählt" on Spiegel Online, one of the most widely read German-language news websites.
two Book "Achtung: Statistik", see Books.
I furthermore give talks on statistics with an "edutainment character" for different kind of events, e.g., at conferences in other scientific fields, in workshops, or for companies.
For more information see http://www.achtung-statistik.de, in German.
I'm also "Mathematik-Botschafter" of the "Stiftung Rechnen", see here.
