Question 579853: For my assignment I am asked to explain what is wrong and why it is wrong. The question reads: If a correlation coefficient of r=0.642 was found between two variables in a sample of paired data that were measured in feet, the value of r would change by a factor of twelve if the data were converted to inches and r was computed again.
I have worked several problems that ask you to switch x and y values to calculate r and in those problems when you switch the x and y values r remains the same and that is clear to me. However, this problem has me stumped.
Thanks for any help or direction you can give me!!

The correlation (r) has nothing to do with the units of x and y.
