Litkenhous Ratings
Mathematical system for ranking sports teams / From Wikipedia, the free encyclopedia
The Litkenhous Difference by Score Ratings system was a mathematical system used to rank football and basketball teams.[1][2] The Litrating system was developed by Vanderbilt University professor Edward E. Litkenhous (1907 – December 22, 1984)[2] and his brother, Francis H. Litkenhous (December 9, 1912 – June 22, 1996).[1][3]
The National Collegiate Athletic Association (NCAA) football records book includes the Litkenhous Ratings as a "major selector" of college football national championships for the seasons 1934 through 1984.[3]
