2. Home/Away data is made up of only two numerical results which 1s and 0s. Would it be appropriate to also include Home/Away in correlation? Explain

Solutions

Expert Solution

Solution:

1. The correlation table shows the correlation between the +/- and Points variable is 0.446, which means there is a moderate positive linear relationship between these two variables.

The correlation table shows the correlation between the +/- and AST variable is 0.354, which means there is a moderate positive linear relationship between these two variables.

The correlation table shows the correlation between the +/- and TOV variable is -0.081, which means there is a weak negative linear relationship between these two variables.

The correlation table shows the correlation between the Points and AST variable is 0.608, which means there is a moderate positive linear relationship between these two variables.

The correlation table shows the correlation between the Points and TOV variable is -0.183, which means there is a Weak negative linear relationship between these two variables.

The correlation table shows the correlation between the AST and TOV variable is -0.077, which means there is a Weak negative linear relationship between these two variables.

2. No, it would not be appropriate to include the Home/Away in correlation because the given variable is categorical and it would not appropriate to find the correlation coefficient here.
