The Long Tail of Application Usage

A long tail is a distribution of some data point where a few data point have a high value, but most of the data points have a much lower value. When sorting the data points by value, there will be a large “head” and a long “tail”.

Application usage displays the “long tail” characteristic: A few screens are used much more than others.
