 Gender Pay Gap Averages
An idea inspired by reporting on the gender pay gap; given two groups (such as males and females) which are then split into three subgroups (such as workers on floor 1, floor 2, floor 3), is it possible for the average of all subgroups to be higher for one gender but the overall average to be higher for the other gender? Instinctively you'd think no, but it is actually possible. Can you create some examples to prove this? PDF here.
