How many of you use averages in order to inform your decisions? I know I do; as an athlete I focused on finding out what the average performance was at major championships to achieve certain placings, so that I could use that information in order to create my own individual goals. As a sports scientist, I use averages a lot – typically I tend to compare the average improvement in one group with the average improvement of another. But is the average actually a useful metric, or is it overused?
