Women's College Basketball RPI Ratings: Women's Hoops Rankings
The NCAA utilizes the women's college basketball RPI ratings as an additional piece of reference material when selecting and seeding teams for the women's basketball tournament. Each year when March Madness rolls around the importance of the RPI(Ratings Index Percentage) tends to get over-hyped by the media and by many women's college basketball analysts across the internet. The NCAA actually considers several factors when evaluating teams for the women's 64-team tournament. Women's college basketball RPI ratings are just one piece of information that the tournament committee has at their disposal.
The formula for the women's college basketball RPI ratings is quite simple. It's based on wins, who you have played, and who your opponents have played. Road wins are weighted the same as home wins. Home losses are weighted the sme as road losses.
The formula for the women's college basketball RPI ratings is quite simple. It's based on wins, who you have played, and who your opponents have played. Road wins are weighted the same as home wins. Home losses are weighted the sme as road losses.
Here is the actual formula for the women's college basketball RPI rankings:
Wins: road wins + home wins
Losses: road losses + home losses
Winning Percentage: Wins/(Wins + Losses)
Overall RPI Formula: 0.25*Winning Percentage + 0.50*Opponents' Average Winning Percentage + 0.25*Opponents' Opponents' Average Winning Percentage
So your own weighted winning percentage accounts for 25% of the formula, the average of your opponents' winning percentages accounts for 50% of the formula, and the average of your opponents' opponents' winning percentages accounts for 25% of the formula. When averaging your opponents' or opponents' opponents' winning percentages, any games against your team are not used in the calculations.
The NCAA maintains the official women's college basketball RPI ratings. They do not reveal the actual figures resulting from the calculations, however they do release the rankings 1 through 338 starting in late-January of each season. The fact that the NCAA does not release the actual figures is not a big deal as the difference between 1 and 100 is typically around 0.15.
As you can see from the RPI formula, strength of schedule plays a large role in the outcome of the rankings. That's what the women's NCAA tournament committee had in mind when RPI ratings began to be calculated for women's college basketball. Note that the weighting of home and road wins/losses was added to the men's RPI formula for the 2004-2005 men's college basketball season, however weights have not been added to the women's RPI calculation.
