Understanding statistical analysis lies at the core of understanding data and most research projects. But outside of the research world, where rigorous training is (or at least should be) required, these concepts are often confusing, or ignored altogether. This leads to all sorts of public misconceptions when it comes to understanding the results of the latest research.
As part of a public engagement project, the British Psychological Society has produced a lovely series of short films to help better educate all to basic statistical concepts. Using dance, the films cover the concepts of correlation, frequency distributions, sampling & standard error, and variance. Plus, one dancer occasionally busts out an excellent Robot, which is always appreciated.
