Today, thanks to James, such traditional measures as runs batted in and batting averages are seen as flawed precursors to more adequate statistics such as on-base percentage, slugging average
and other recently developed measures.
He would fix this primarily by making the team more aggressive in the annual amateur draft (as the real new GM, Sandy Alderson, is doing), spending as much money as possible on developing the draftees and looking for good pickups among young prospects who exhibit promise measured by moderately newfangled statistics such as on-base plus slugging average
(OPS) for hitters and strikeouts and walks per nine innings for pitchers.
Two variables were chosen to represent the player's productivity at the plate, slugging average
and on-base-percentage plus slugging average
2) Our season-variant data for hitters are age, age squared, a dummy variable for each team's primary designated hitter, and performance data that include games played as well as slugging average
, home runs per game, stolen base percentage, runs batted in per game, walks per game, strikeouts per game, hit by pitch per game, sacrifice flies per game, and runs scored per game.
For each of the three age groups, hitters' on-base percentage plus slugging average
(OPS) and pitchers' walks plus hits divided by innings pitched (WHIP) in 2003 were compared to the seasons before and after the players filed for free agency.
But in the past 11 games, Sansoe's on-base average is up 30 points, his batting average nearly 50 and his slugging average
more than 70.
It's a hitter's slugging average
, which measures how many extra base hits he gets.
For example, when offense is measured using the slugging average
, we find that a team hitting one standard deviation above the sample mean (equal to an additional 0.
In small groups, students were to discuss and analyze the problem until they constructed an understanding of the concept of slugging average
and were able to use this understanding to devise a way of computing it.
Jimmy" Foxx, first baseman, who had a career slugging average
Although he generally does quite well, many technical terms are unexplained, including marginal revenue and marginal cost, slugging average
, and earned run average.
none represents a loss of at least 30 points in batting average, 40 points in on-base percentage, and 70 points in slugging average
, that's a significant disadvantage.
