Understanding The Power Rank

Most youth sports leagues report team standings, schedules and scores.  This is valuable information for determining the relative strength of the teams in your child’s sports league.  There are many sites on the web, which generate relative sports rankings.  Most are computed mathematically and are based upon how well teams play against one another.  The following is an explanation of how these values are determined.
First, check this spreadsheet for a handy reference.This mathematical model rates teams based upon three factors; average points per game, average goal differential, and strength of opponent.  Average points per game (APG) is calculated by taking the total points assigned for wins and ties and dividing by the total games played.  Average goal differential (AGD) is calculated as the difference between goals for and goals against and dividing by the total games played.  A team’s strength of opponent (SO) is calculated by averaging the AGD for all of the opponents contested to date.  The composite rank, a measure of relative strength, is computed by summing the AGD and the SO.  The POWER RANK is the sum of the composite rank and the APG.This may sound overly complicated, just give it some time, noodle with the spreadsheet, in time, it will make perfect sense.  It has been my experience that this model is a fairly accurate means to evaluate team strength.The associated spreadsheet has two tabs, one is for calculations, and the other is a copy over of the values.  The copied values are handy for sorting and filtering.
