Why Statistics Matter

About the lecture

In this lecture, we look to understand what statistics are and why they matter, focusing on three examples: (i) why a drug tester might be fired for finding that their drug lowers the blood pressure of people who had previously been reading as having high blood pressure; (ii) why reinforcing commonly damaged parts of fighter planes could have no effect on the number who safely return from battle; (iii) how you could prove that a coin is biased in a coin flip.
