In this TED talk, Oxford mathematician Peter Donnelly describes the common mistakes humans make in interpreting statistics along with the impact these errors have on the outcome of criminal trials.
It’s a great video to show during intro stats courses and to get students thinking about what statistics is all about. For classes it’s better to pause and ask them questions like:
- Which sequence of head and tails will take longer to see: HTT or HTH?
- If a test is 99% accurate for indicating if you have a disease and you test positive, what is the probability that you have the disease?
