Rolling averages as a way to show more accurately the current trend

Not many law departments calculate rolling averages, such as for what they spend per month on outside counsel, but it is a useful tool to show up-to-the-month patterns in time-interval data. Rolling averages can show your progress since they convey recent trends rather than overall averages. I write about rolling averages and how to calculate and display them in my Morrison on Metrics column, published Jan. 30, 2012, with InsideCounsel.com. The full column about rolling averages is available online.
