A)The correlation coefficient measures the direction and the strength of the linear relationship between two variables. B)The coefficient of variation can be used to establish a linear relationship between two variables. C)The scatter plot cannot be used to form expectations about the direction of a linear relationship between two variables.

Which of the following measures the direction of the linear relationship between two variables but does not measure the strength of the relationship? coefficient of variation correlation coefficient covariance variance
Adi S.
The correlation coefficient is used to measure a. A specific value of the y-variable given a specific value of the x-variable b. A specific value of the x-variable given a specific value of the y-variable c. The strength of the linear relationship between the x and y variables d. None of the above
