Range Factor Records and Details
What is Range Factor ?
Range factor is a metric that shows how often a defensive player records an putout or assist per innings played. It is calculated by dividing chances accepted by innings played by a player or team over a given period of time Generally, for Range Factor, higher is better. (Source)
What is a good Range Factor?
What does good Range Factor mean? "Good" baseball stats can be very subjective and mean different things to different people.
I have attempted to quantify good and bad by taking season and career stats for MLB players with a minimum number
of played outs. In this case 100 for career and 50 for a season. To find good and bad within this cohort of players I calculated the first and third quartiles,
anything between these quartiles I consider average. This makes up the middle 50% of players. In an example
where higher is better for a stat, below the first quartile (bottom 25% of players) would be bad and above the 3rd
quartile (top 25% of players) would be good. For stats where lower is better, flip around good and bad.
Career, Season, and Season Average Range Factor Records
For my hot take on Range Factor records most of the same rules apply from the first section. To be considered for my
prestigious lists the player must meet a certain threshold of played outs. Since this is a Fielding stat to be considered
for the career list the player must have over 100 played outs, for a season consideration the player must have
had 75 played outs. Additionally, the player's final game must have been after 1899.
