Which of the following statements concerning the linear correlation coefficient are true?

Question

I: If the linear correlation coefficient for two variables is zero, then there is no relationship between the variables.

III: The value of the linear correlation coefficient always lies between –1 and 1.
IV: A linear correlation coefficient of 0.62 suggests a stronger linear relationship than a linear correlation coefficient of –0.82.
