Correlation Coefficients
As you can see here, I've been known to waste time not only looking at baseball statistics, but also tearing them apart trying to figure out their value.
The purpose of the game is to score runs, of course. However, Runs scored and Runs Batted In are both dependent on the performance batting in front of and behind the hitter who's R & RBI totals are being evaluated. How, then, do we determine which statistics best measure the ability to put runs on the board?
Well, the solution I've decided on is correlation coefficients. So far, I've found the correlation coefficients of ten statistics to Runs scored by team in the year 2004. Below is a table.
