Statistics explained with the help of modern dance

If you're the type of person who really needs some good visuals to make a concept stick in your head, this series of YouTube videos made by the British Psychological Society Media Centre will help you remember the meanings behind statistical concepts like "correlation", "frequency distributions", and "sampling error". There are four videos in the series so far, and they do a great job of painting pictures around abstract ideas. Bonus: Soothing music.

Big Data meets Bigfoot

Big Data meets Bigfoot in Penn State PhD candidate Joshua Stevens's visualization of nearly a century of Sasquatch sighting reports in the US and Canada. Stevens mapped and graphed more than 3,000 sightings included in the Bigfoot Field Researchers Organizations's database of geocoded and timestamped reports. Stevens writes:

Right away you can see that sightings are not evenly distributed. At first glance, it looks a lot like a map of population distribution. After all, you would expect sightings to be the most frequent in areas where there are a lot of people. But a bivariate view of the data shows a very different story. There are distinct regions where sightings are incredibly common, despite a very sparse population. On the other hand, in some of the most densely populated areas sasquatch sightings are exceedingly rare.
