2007 BCS Computer Rankings
In American college football, the 2007 BCS computer rankings are a part of the Bowl Championship Series (BCS) formula that determines who plays in the BCS National Championship Game as well as several other bowl games. Each computer system was developed using different methods which attempts to rank the teams' performance. For 2007, the highest and lowest rankings for a team are dropped and the remaining four rankings are summed. A team ranked #1 by a computer system is given 25 points, #2 is given 24 points and so forth. The summed values are then divided by 100 (the maximum value a team can earn if they received four first place votes that were summed). The values are then ranked by percentage. This percentage ranking is then averaged with the Coaches Poll and Harris Poll average rankings, each receiving equal weight, and the results become the BCS Rankings. BCS computer rankings average For 2007, the rankings released beginning with the eighth week of the season on October 13. The ...

College Football
College football (french: Football universitaire) refers to gridiron football played by teams of student athletes. It was through college football play that American football rules first gained popularity in the United States. Unlike most other sports in North America, no official minor league farm organizations exist in American or Canadian football. Therefore, college football is generally considered to be the second tier of American and Canadian football; one step ahead of high school competition, and one step below professional competition (the NFL). In some areas of the US, especially the South and the Midwest, college football is more popular than professional football, and for much of the 20th century college football was seen as more prestigious. A player's performance in college football directly impacts his chances of playing professional football. The best collegiate players will typically declare for the professional draft after three to four years of collegia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jeff Sagarin
Jeff Sagarin is an American sports statistician known for his development of a method for ranking and rating sports teams in a variety of sports.

NCAA Division III
NCAA Division III (D-III) is a division of the National Collegiate Athletic Association (NCAA) in the United States. D-III consists of athletic programs at colleges and universities that choose not to offer athletic scholarships to their student-athletes. The NCAA's first split was into two divisions, the University and College Divisions, in 1956, the College Division was formed for smaller schools that did not have the resources of the major athletic programs across the country. The College Division split again in 1973 when the NCAA went to its current naming convention: Division I, Division II, and Division III. Division III schools are not allowed to offer athletic scholarships, while D-II schools can. Division III is the NCAA's largest division with around 450 member institutions, which are 80% private and 20% public. The median undergraduate enrollment of D-III schools is about 2,750, although the range is from 418 to over 38,000. Approximately 40% of all NCAA st ...

NCAA Division II
NCAA Division II (D-II) is an intermediate-level division of competition in the National Collegiate Athletic Association (NCAA). It offers an alternative to both the larger and better-funded Division I and to the scholarship-free environment offered in Division III. Before 1973, the NCAA's smaller schools were grouped together in the College Division. In 1973, the College Division split in two when the NCAA began using numeric designations for its competitions. The College Division members who wanted to offer athletic scholarships or compete against those who did became Division II, while those who chose not to offer athletic scholarships became Division III. Nationally, ESPN televises the championship game in football, CBS televises the men's basketball championship, and ESPN2 televises the women's basketball championship. Stadium broadcasts six football games on Thursdays during the regular season, and one men's basketball game per week on Saturdays during that spo ...

NCAA Division I Football Championship Subdivision
The NCAA Division I Football Championship Subdivision (FCS), formerly known as Division I-AA, is the second-highest level of college football in the United States, after the Football Bowl Subdivision. Sponsored by the National Collegiate Athletic Association (NCAA), the FCS level comprises 130 teams in 15 conferences as of the 2022 season. The FCS designation is only tied to football with the non-football sports programs of each school generally competing in NCAA Division I. History From 1906 to 1955, the NCAA had no divisional structure for member schools. Prior to the 1956 college football season, schools were organized into an upper NCAA University Division and lower NCAA College Division. From 1973 to 1977, all schools participated in a single NCAA Division I group. Prior to the 1978 season, schools were again organized into upper NCAA Division I-A and lower NCAA Division I-AA groupings. These two divisions were renamed as NCAA Division I FBS and NCAA Division I FCS pri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pairwise Comparison
Pairwise comparison generally is any process of comparing entities in pairs to judge which of each entity is preferred, or has a greater amount of some quantitative property, or whether or not the two entities are identical. The method of pairwise comparison is used in the scientific study of preferences, attitudes, voting systems, social choice, public choice, requirements engineering and multiagent AI systems. In psychology literature, it is often referred to as paired comparison. Prominent psychometrician L. L. Thurstone first introduced a scientific approach to using pairwise comparisons for measurement in 1927, which he referred to as the law of comparative judgment. Thurstone linked this approach to psychophysical theory developed by Ernst Heinrich Weber and Gustav Fechner. Thurstone demonstrated that the method can be used to order items along a dimension such as preference or importance using an interval-type scale. Mathematician Ernst Zermelo (1929) first describ ...

Peter Wolfe (Sports Rankings)
The Bowl Championship Series (BCS) was a selection system that created four or five bowl game match-ups involving eight or ten of the top ranked teams in the NCAA Division I Football Bowl Subdivision (FBS) of American college football, including an opportunity for the top two teams to compete in the BCS National Championship Game. The system was in place for the 1998 through 2013 seasons and in 2014 was replaced by the College Football Playoff. The BCS relied on a combination of polls and computer selection methods to determine relative team rankings, and to narrow the field to two teams to play in the BCS National Championship Game held after the other college bowl games (the game rotated among four existing bowl games from the 1998 to 2005 season, and was a separate game from the 2006 to 2013 seasons). The American Football Coaches Association (AFCA) was contractually bound to vote the winner of this game as the BCS National Champion and the contract signed by each conference ...

Elo Rating System
The Elo rating system is a method for calculating the relative skill levels of players in zero-sum games such as chess. It is named after its creator Arpad Elo, a Hungarian-American physics professor. The Elo system was invented as an improved chess-rating system over the previously used Harkness system, but is also used as a rating system in association football, American football, baseball, basketball, pool, table tennis, and various board games and esports. The difference in the ratings between two players serves as a predictor of the outcome of a match. Two players with equal ratings who play against each other are expected to score an equal number of wins. A player whose rating is 100 points greater than their opponent's is expected to score 64%; if the difference is 200 points, then the expected score for the stronger player is 76%. A player's Elo rating is represented by a number which may change depending on the outcome of rated games played. After every game, the wi ...

Bayesian Probability
Bayesian probability is an interpretation of the concept of probability, in which, instead of frequency or propensity of some phenomenon, probability is interpreted as reasonable expectation representing a state of knowledge or as quantification of a personal belief. The Bayesian interpretation of probability can be seen as an extension of propositional logic that enables reasoning with hypotheses; that is, with propositions whose truth or falsity is unknown. In the Bayesian view, a probability is assigned to a hypothesis, whereas under frequentist inference, a hypothesis is typically tested without being assigned a probability. Bayesian probability belongs to the category of evidential probabilities; to evaluate the probability of a hypothesis, the Bayesian probabilist specifies a prior probability. This, in turn, is then updated to a posterior probability in the light of new, relevant data (evidence). The Bayesian interpretation provides a standard set of procedures and formu ...
