How are they on college football teams?

University football teams in the US are evaluated in two ways: human voters and computers that use mathematical patterns. Some rankings are public opinion surveys that use qualified voters who have submitted ballots that indicate their views on the best teams in order. Further evaluation compiles computers based on factors, such as game results, game scores, games, and possibly other samples criteria. At the highest level of American college football, a collection of both types of charts was used to determine which two teams will play in the National Championship of the Championship (BCS) series.

voters in university football surveys are selected by organizations that perform voting. In most cases, voters are journalists, coaches, school staff or former players. Since the mid -1930s, the Associated Press has addressed athletes and operators of broadcasting. Since 1950, the coaches were exposed to have been sponsored by various organizations, including uNITED PRESS INTERNATIONAL, USA Today and ESPN. The Harris interactive survey, which uses a combination of media workers, coaches, school administrators and foreign players, was first performed in 2005.

computer rating

There are many mathematical formulas that use computers to evaluate college football teams. The six most important are those developed by Jeff Sagarin, Richard Billingsley, Wesley Colley, Kenneth Massey, Dr. Peter Wolf and the team of Jeff Anderson and Chris Hester. The factors and methods used each of them differ. For example, some patterns do not take into account the game score - only whether the team won or lost. Not all patterns used by computers have been published.

edition

College rankings are usually released every week during the stains. Many of them are also published before the first game of the season and are known as a ribPreseason. Before the end of the sixties, it was unusual that public opinion surveys were updated after the games to the inch games, which are other games at the end of the season playing successful teams, but have become the norm since then. Some public opinion surveys avoid the ranking only after the first few weeks of the season, by believing that prejudices and previous season should not affect the ranking of the current season.

Number of teams placed

The evaluation based on voter ballots usually includes the 25 best teams, and any other teams that won votes were honorable recognition of their voting sums. Before the 1990s, some public opinion surveys often reported only the top 10 or 20 best teams. Computer charts usually include each team - more than 100 of them in the highest college football division.

A MASTRY MASTERY SCHEX

since 1998, national Collegiate Athletic Association (Ncaa) started using BCS to determine which football teams will play in the Championship for its highest competition, which was named Subdivizi Football Bowl (FBS). These assessments are also used to determine which teams will play in several other Bowl games. The BCS system combines the most important human surveys and computer evaluation along with other factors to another set of ranking. This system is regularly evaluated by NCAA and changes could be made between seasons, if the organization of the organization determines the necessary adjustments.

Lower Division

Although most people are more familiar with FBS rankings, there are also rankings for football teams at lower NCAA levels and for teams that belong to the National Association of Mesicoligia Athletics (NAIA), which is for small schools. Like FBS voters' charts, those for lower levels are usually based on ballots submitted by people such as media, coaches or yinschool employees. One difference is that public opinion surveys are often carried out on a regional basis, because it is more difficult for voters to have a great knowledge of teams of small universities that are in other areas. In some cases, these assessments could be compiled on regional and national basis.
