A month ago I wrote about an experiment carried out by Lawrenceville High School to see how well pupils would score resitting tests after their summer break. The results were pretty shocking in showing how little the September test results reflected retained knowledge after three months.
Now I have been pointed to much more worrying statistics.
I met up with Danny Dorling. He is a professor of geography at the University of Oxford and specialises in inequality. He pointed me towards an article he published with Natasha Stotesbury in Statistics Views. It has the snappy title: “Understanding income inequality and its implications: why better statistics are needed”.
