QUESTION: How do you calculate Slugging %..... what does it mean.??
How do you calculate On Base %..... What does it mean..??
ANSWER: Jay,
Slugging percentage and On base percentage are important offensive statistics and help the coach place batters in the line up. Batting average doesn't tell the whole story.
Slugging Percentage = No. of bases on hits/At bats
On base percentage = No of hits + on by error + walks/at bats + on by error + walks
For on base percentage you don't credit for getting on base if someone else gets out (Fielders Choice).
Lets use these statisics for our example. The scenario is a weekend tournament. 88 at bats, 28 hits, 3 triples, 10 doubles, 15 singles, 5 base runners on from errors, and 8 walks.
Start with the simple, Batting average 28/88= .318
Slugging percentage 44/88=.500 The 44 comes from the number bases from triples (9) + the number of bases from doubles (20) + the number of bases from singles (15).
On base percentage 41/101 = .406
My hitters with low slugging percent and high on base percent are typically my table setters the 1 and 2 hitters. High slugging gpercentage gets the 3,4,5 spots.

QUESTION: Does Hit-by-pitch count in the OB% calculation..??
also, how do you calculate a pitcher's ERA..??
Answer
Going from memory, without looking it up, I would say that hit by pitch does count to OB%. Some kids do get hit more than others for some reason.
ERA
ERA = (Earned Runs X Innings Pitched) / 7
If you can't use a full inning ERA = (Earned Runs X Outs Recorded)/21
