Correlation, Part 5

For an explanation of Correlation, go here and for the other parts, go here.
This is the correlation of Babip to Runs: BABIP is batting average on balls in play: it shows you the percent of the time you get a hit when the ball is put in play (Home runs are excluded.)
The correlation was .57 (remember 1 is the best) and the R^2 was .33, which shows the percent of variance.
The equation of the line of regression (or best fit) was f(x)=0x+.23 (in the y=mx+b model)
