Identify the true statements about the correlation coefficient, r. When the data points in a scatter plot are randomly scattered, the correlation between the two variables is weak or nonexistent. The correlation coefficient is not affected by outliers. A correlation coefficient of zero means that no relationship exists between the two variables. 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 value of r ranges from negative one to positive one.
