The Relativity Index

Final Statistics for the 2010 Season

About the Relativity Index
The Relativity Index measures the performance of each team relative to the performance of its opponents in all other games. Essentially, it adjusts for the quality of competition each team faces, and spits out a number that tells us how greatly a team overachieved, or how badly a team underachieved, relative to the quality of competition.

For example, if Team A scores 25.0 PPG, and its opponents surrender 20 PPG in all of their other contests, Team A is +5.0 PPG on offense. If Team A surrenders 20 PPG, and its opponents score 25 PPG in all of their other contests, Team A is +5.0 on defense. This equates to a total Relativity Index score of +10.0 PPG. In other words, Team A is 10 points better than the average performance of its opponents.
