Calculating Statistics__Many people like to calculate player statistics. I'm not one of them,
but I decided to add a page about it anyway. I will use the following symbols in
calculating the statistics:

(+) addition, (-) subtraction, (*) multiplication, and (/) division.

**Offensive
Statistics**

**Base-on-balls Percentage***
*(total walks) / (plate appearances)

__ Batting Average__(total hits) / (official at-bats)

At-bats do not include walks, sacrifice flies, sacrifice bunts, obstruction calls, catcher's interference, or being hit by a pitch. If a player makes it safely on base due to an error, it is an at-bat, but not a hit.

**Home Run Ratio***
*(at-bats) / (home runs)

__ On-base Percentage__(hits + walks + hits by pitch) / (at-bats + walks + hits by pitch + sacrifice
flies)

__ Slugging Average__(total bases) / (at-bats)

The number of total bases only includes those obtained from hits; not from errors, walks, or interference calls.

**Stolen Base Percentage***
*(stolen bases) / (total attempts)

**Strikeout Ratio***
*(at-bats) / (strikeouts)

**Defensive Statistics**

__ Fielding Average__(total putouts + assists) / (putouts + assists + errors)

**Pitching Statistics**

__ Earned Run Average__(earned runs * 9) / (innings pitched)

__ Opponents' Batting Average__(hits allowed) / (at bats allowed)

**Winning Percentage***
*(games won) / (games won + games lost)

*Team Statistics*

__ Won-Lost Percentage__(wins) / (wins + losses)

*Other Statistics*

Here are a couple of "unofficial" statistics.

__ Fielder's Range Factor__(putouts + assists) / (games)

__ Runs Created__[(hits + walks - caught stealing) * (total bases + (stolen bases * 0.55)] /

(at-bats + walks)
