Maths podcast on stochasticity
How big a role does randomness play in our lives? Do we live in a world of magic and meaning or … is it all just chance and happenstance? To tackle this question, we look at the role chance and randomness play in sports, lottery tickets, and even the cells in our own body.

Now, you don't have to have a degree in statistics in order to conduct an effective "interview" with your data. But you do need to know a few basics. Here, described in plain English, are some basic concepts in statistics that every writer should know...
