## What is a good Walks Allowed Per 9 Innings?

What does good Walks Allowed Per 9 Innings 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 pitchers with a minimum number
of pitched 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.

prestigious lists the player must meet a certain threshold of pitched outs. Since this is a Pitching stat to be considered
for the career list the player must have over 100 pitched outs, for a season consideration the player must have
had 75 pitched outs. Additionally, the player's final game must have been after 1899.
