Text: Demonstrate your essential knowledge in statistics by choosing a statement that does not describe a characteristic of the coefficient of correlation. It measures the linear relationship between two interval or ratio scaled variables. A value near zero indicates little association between the variables. It is identified by the letter r.

Identify the true statements about the correlation coefficient, r. A correlation coefficient of zero means that no relationship exists between the two variables. The correlation coefficient is not affected by outliers. The absolute value of r describes the magnitude of the association between two variables. The value of r ranges from negative one to positive one. If two variables are negatively correlated, when one variable increases, the other variable also increases. When the data points in a scatter plot are randomly scattered, the correlation between the two variables is weak.

Identify the true statements about the correlation coefficient, ?r. If two variables are negatively correlated, when one variable increases, the other variable also increases. The sign of ?r describes the direction of the association between two variables. 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 negative one to positive one. A correlation coefficient of zero means that no relationship exists between the two variables.
Describe the relationship between two variables when the correlation coefficient $r$ is (a) near -1 (b) near 0 (c) near 1
