Ratings Percentage Index
The Rating Percentage Index (RPI) has been used by the NCAA since 1981 to supplement the selection of at-large teams and the seeding of all teams for the NCAA Basketball tournament.
Ratings percentage index
The Rating Percentage Index is a quantity used to rank sports teams based upon a team's wins and losses and its strength of schedule. In its current formulation, the index comprises a team's winning percentage (25%), its opponents' winning percentage (50%), and the winning percentage of those opponents' opponents (25%). The opponents' winning percentage and the winning percentage of those opponents' opponents both comprise the strength of schedule (SOS). Thus, the SOS accounts for 75% of the RPI calculation and is 2/3 its opponents' winning percentage and 1/3 times its opponents' opponents' winning percentage.
I have a question, not answer. What does the rpi's in college basketball mean?
how is the rpi calculated in college basketball.
Yes, a high RPI can influence the tournament selection committees selection for the tournament teams.
In college basketball, SOS means 'Strength of Schedule.' This basically means that, using formulas that the NCAA uses (national ranking, RPI, where they played etc.), how good were the opponents that a team played during the season.

Relative power index
The RPI (Ratings Pecentage Index) is a complex formula used to rank NCAA Division I basketball teams A simplified estimate would be 25% is based on a team's winning percentage (with road games weighted about twice as heavily as road games), 50% is based on that team's opponents' win% (unweighted), and 25% based on the opponents' opponents' win% (also unweighted). Teams are given a numerical score, and then ranked 1-347, with 1 being the best.
A high RPI (Rating Percentage Index) indicates a stronger team or player performance compared to a low RPI. Teams with a high RPI are typically ranked higher and considered more successful.
5 = Players in a Basketball Team (USA)players on a basketball team?
it is a basketball team and it is a basketball company too . It was borned in 1993
A team's Strength of Schedual is determined on a ranking of the caliber of opponents they will face that season. For example, UCONN had the #1 SOS for the 2011-12 season, as they were NCAA Champions in the 2010-2011 season. This can be basically set up pre-season. A team's RPI (Rating Percentage Index) is largly used when March Madness is beginning. The committee who sets up the seeding will look at each team's RPI to determine their seed. The RPI includes Quality Wins, the strength of their conference, and basically the strength of their schedual. So in a way, they are similar, but SOS is involved in the RPI calculations.
The RPI calculates 3 percentages: team's winning percentage, opponents' winning percentage, and opponents' opponents' winning percentage.?To calculate?the team's winning percentage:Wins: home wins * 0.6 + road wins * 1.4 + neutral wins?Losses: road losses * 0.6 + home losses * 1.4 + neutral losses?Then calculate your winning percentage using wins / (wins + losses). This % is weighted 25%.Opponents' winning percentage is calculated using the exact same method as shown above, however exclude all games played with the team (that's RPI is being calculated). This % is then weighted 50%.?Opponents' opponents' winning percentage is calculated by the average of the team's oppenents adjusted winning %. Simply, use the same method above for calculating the oppenents' winning percentage, however using it for the opponents' opponent and excluding only the team once again (not the opponent). Repeat this method for each team, and average the winning percentage. This % is then weighted 25%.?Finally, add up all scaled RPI points, and get a total RPI ranking.
