Which do you think is more valuable in expressing the relationship between calories and sugarlong dashthe covariance or the coefficient of​ correlation? Explain.
A.
The coefficient of correlation is more valuable. It is the better measure for positive relationships. The coefficient of correlation is easier to interpret because it can only take a value between minus1 and​ 1, inclusive, while the covariance can be any real value.
B.
The covariance is more valuable. It is an exact measure of the strength of a linear relationship. The covariance is easier to interpret because it can be any real​ value, while the coefficient of correlation can only take a value between minus1 and​ 1, inclusive.
C.
The covariance is more valuable. It is not susceptible to the negative effects of lurking variables. The covariance is easier to interpret because it can be any real​ value, while the coefficient of correlation can only take a value between minus1 and​ 1, inclusive.
D.
The coefficient of correlation is more valuable. It can be used to determine the relative strength of a linear relationship. The coefficient of correlation is easier to interpret because it can only take a value between minus1 and​ 1, inclusive, while the covariance can be any real value.
