About the Application

Data sets to work with:

2012, 2011 : Complete Data that should be used to test formula results against historical outcomes.
2013: Incoming Data to test formulas and provide fair match ups at Nationals.
2010-2004: Limited incomplete results to use as examples. (GVSU & MSU are mostly complete)

These results are compiled in publicly available Google Drive Spreadsheets, and could be transferred into a MySQL database if needed. Most likely, they will be transferred.

Problems Identified:

The NCDA is a small, divided league, mostly concentrated in the Midwest with 25 Member Teams. There isn't a set or required amount of games per season, nor required opponents, and in many ways the Nationals weekend is the only league matches a Team could get all year. In order to be a fair representation, Rankings needs to take in effect the following:

Teams can't be too penalized for lack of play because of distance issues; we'll just lose those teams and hinder expansion. Teams should also be rewarded for their monetary commitment to playing games and traveling. Ultimately we should decide our own fate, but use the elements of history to best develop a system that meets the unique needs of our brand of dodgeball.


Any ranking system we come up with is ultimately designed for the Nationals event. Considering Nationals, the Event consists of two portions, pool play and a tournament bracket.

Pool play is used by many teams to be a considerable amount of that team's matches during the course of the Season. The goal has always been to give teams games against teams they wouldn't normally meet because of geographic/funding/travel difficulties. Pool play matches should be scheduled to give a competing team:

  1. A fun and valuable experience (matches relating to hard, even, and easy levels of play).
  2. Matches against opponents they might not have played before (because of the sheer amount of games played in the Season, some Teams can't be guaranteed never-played-before teams)
Based off the outcome of the Regular Season and Nationals Pool Play results, the Rankings determine fair seeding for the Tournament bracket.

Conventional tournament seeding dictates high seeds against low seeds, but this assumes that the seed has a reliable "predictive accuracy". The IRB rankings explanations explains: "If, over a period of time, the system tends to be good at predicting which side will win each match, then we can be confident that it is presenting an accurate and reliable picture of current strength, and responding appropriately to changes in form." A reliable predictive accuracy is what we should be focused on creating, in regards to a dodgeball ranking system.
