Suppose a researcher converts all of the throwing distances to inches by multiplying every Y value by 12. The transformed data are shown in the table below. Compute the correlation between X and the transformed Y values. How is the correlation affected when one of the variables is transformed (compared to before the Y values were multiplied by 12).
