Medical Statistics III: Hypothesis Testing

Statistics is a bit of a mystery to most of us. Help is here from former maths teacher and current surgical trainee, Rob Radcliffe. In the third in this series explaining medical statistics, Rob explains hypothesis testing. This is fundamental to just about all we do when cam paring data in trials. The null hypothesis is explained and when it is safe to reject it (how to tell if 2 distributions are the same or different and by how much). This podcast also makes it clear where the "magic" p<0.05 comes from and what it actually means.
Understand the content of this podcast and you will be 95% (p<0.05) of the way there to understanding medical statistics!
