Dewan: The best and worst hitters' parks in baseball

From SABR member John Dewan at ACTA Sports on November 28, 2012:

The perception of those bookends is correct, but it is not comprehensive. They are not the only parks that have dramatic effects on the run environment.

We measure park factors in indices that compare statistics compiled by both teams in a specific home park and then in all other parks. If a park has an index of 110 in home runs, for example, it allows 10 percent more home runs than average. If a park has an index of 90 in home runs, it allows 10 percent fewer home runs than average. The Bill James Handbook 2013 has a variety of park indices for all 30 teams.
