The formula for the National Football League (NFL) quarterback passer rating depends on five variables: number of attempted passes, completed passes, passing yards, touchdown passes, and interceptions. Passer ratings can range from a low score of 0.0 to a high score of 158.3. You input values for each statistic to create a score. The Demonstration visually maps the result in a three-dimensional graph to help you better understand the relationship of each variable to the final result.
The sliders are set for values that may occur within a single game. You can open each and directly input higher values to reflect data added over many games. A few NFL records are bookmarked along with one example of a perfect game.
