I am not entirely sure I have used the correct type of standard deviation, but I managed this:
The bar for Wii doesn't quite work, as the lowest score is more than the low of standard deviation.... I think I should just be using first 1/4, 2nd 1/4 etc instead of standard deviation. Still it shows where the majority of us fit, with anyone scoring above or below the blue boxes being outliers. (this is for the first 4 weeks scores added together by the way)
