Statistics 10 Lab#2:Batter Up

The graph shows a linear relationship between at bats and runs. Its not perfectly linear but you can see that as the number of bats goes up the number of runs seem to go up as well. Can you make an accurate prediction? Not exactly but you would want the number of at bats to go up as the graph indicates your runs will go up too.

From the residual plot shown in figure 2 , \(r^2\) is given below so taking \(\sqrt{r^2}=.608\), gives the correlation relation.A value between \(0.3<r<0.7\) is a moderate correlation so we can certainly say there is a correlation between at bats and runs but its not very strong.
