For some people, shopping for clothes can feel like a step into Dante’s Inferno, all suffering and punishment. Even for those that do enjoy shopping it can hard to find something that fits well. The data for size is the focus of this episode of Stats+Stories with guest Jordi Prats who recently wrote an article about the issue in Significance Magazine. Jordi Prats studied Biology at the University of Barcelona, where his interest for statistics was born. He then obtained my PhD at the Civil Engineering School of the Polytechnic University of Catalonia before becoming an environmental modeler, specializing in Hydrology, Freshwater Ecology, and Lake Hydrodynamics. He has worked in the public and the private sectors in France and Spain and has collaborated with Significance since 2011 where he is now a member of the editorial board.
