Following on from my post on handling difficult data, I was perusing my Facebook feed and I was very surprised to see this map:
This represents the number of heavy metal bands per 100,000 people. Now, compare this to the reading achievement map in my previous post, showing countries with the biggest reading gap between boys and girls:
The maps look very similar… now, this is a semi-serious post, and you should not attempt to read anything significant into this. You’d need to delve deeper in the data. But let’s ask the question anyway: Is there a correlation between the density of heavy metal bands and the reading ability of girls ? Does Ingrid turn to Jane Austen because Sven wants to be like Metallica ? Or, more significantly, does a liking for heavy metal indicate a better education system ? The countries with the darker colour, irrespective of gender, have a higher education achievement.
