More or Less: Behind the Stats

Evo Morales, Bolivia’s longest-serving leader and first indigenous president, stepped down last week amid weeks of protests sparked by a dispute over a recent presidential election in the country. His opponents say the election was rigged but the embattled former president said it was a cunning coup. We take a closer look at the election results and ask if statistics can tell whether it was fair or fraudulent. Dr Calla Hummel of the University of Miami and Professor Romulo Chumacero of the University of Chile join Ruth Alexander to discuss.

Two statistics about reducing your risk of an early death made headlines around the world recently. The first seems to be a great reason to add a four-legged friend to your life. It suggests that owning a dog is tied to lowering your chance of dying early by nearly a quarter. The second statistic claims that even a minimal amount of running is linked to reducing your risk of premature death by up to 30%. Ruth Alexander finds out what’s behind these numbers and we hear from epidemiologist, Gideon Meyerowitz-Katz. Producer: Darin Graham

In the United States, some police jurisdictions didn’t send off DNA evidence from people who were raped for testing in a crime lab and for uploading into a national criminal database. Instead, the sets of evidence, known as rape kits, were sat on shelves and in warehouses. It’s estimated that hundreds of thousands need processing. In this edition, Ruth Alexander explores how some jurisdictions are testing the kits now and using the data to catch criminals.
