Which of the following statements regarding the correlation coefficient is true? A large value for the correlation coefficient guarantees that our data are linear A correlation coefficient of 0 means that the two variables are perfectly linearly related The correlation coefficient is a value between 0 and 1 A correlation coefficient of -1 means that as one variable increases, the other decreases

Which of the following statements regarding the correlation coefficient is false? A. A high correlation coefficient tells us the data are linear. B. A correlation coefficient of 1 means that two variables are perfectly linearly related. C. The correlation coefficient is a value between -1 and 1. D. A correlation coefficient of -1 means that as one variable increases, the other decreases.

Identify the true statements about the correlation coefficient: If two variables are negatively correlated, when one variable increases, the other variable also decreases. The correlation coefficient is not affected by outliers. When the data points in a scatter plot fall closely around a straight line that is either increasing or decreasing, the correlation between the two variables is strong. The value of r ranges from -1 to +1. A correlation coefficient of zero means that no relationship exists between the two variables. The absolute value of r describes the magnitude of the association between two variables.
