Ever wonder how baseball and softball players come up with
all those averages and percentages? Well, hereís a quick guide
to a few common stats.
∑ Batting Average: How often a batter hits safely. Calculation:
Take the total number of a playerís hits (singles, doubles,
triples, and homeruns) and divide by the number of times the
player bats. Round off the result to three decimal places.
∑ Slugging Percentage: How often a batter hits
for extra bases (doubles, triples, homers). Calculation: Determine
total of bases for a hit (doubles count as two, triples as three,
etc.). Then divide the total bases by the total number of at-bats.
Round off to three decimal places.
∑ On Base Percentage: The percentage of times
a player reaches any base. Calculation: Take the number of hits,
walks, and times hit by a pitch and add them together. Then
divide it by the total number of at-bats, walks, times hit by
a pitch, and sacrifice flys added together. Round off to three
∑ Earned Run Average (E.R.A.): How many runs a pitcher
allows to score per game on average. Calculation: Since pitchers
donít always pitch the whole game, take the number of runs given
up and multiply it by nine. Then divide the product by the number
of innings pitched. Round off to two decimal places.
∑ Fielding Percentage: How well a defensive player fields
his position. Calculation: Add the number of defensive putouts
and assists. Divide that by the total number of putouts, assists,
and errors. Round off to three decimal places.
