In baseball, isolated power or ISO is a sabermetric computation used to measure a batter's raw power. One formula is slugging percentage minus batting average.
I S O = S L G − A V G {\displaystyle ISO=SLG-AVG}
= T B − H A B {\displaystyle ={\frac {{\mathit {TB}}-H}{AB}}}
= ( 1 B ) + ( 2 × 2 B ) + ( 3 × 3 B ) + ( 4 × H R ) A B − H A B {\displaystyle ={\frac {({\mathit {1B}})+(2\times {\mathit {2B}})+(3\times {\mathit {3B}})+(4\times {\mathit {HR}})}{AB}}-{\frac {H}{AB}}}
International Standardization Organization Erroneously. Actually The Word Is Greek for "equal" and Iso Is The Name of The Organization. The Expansion Is A Backronym.
