Identify the true statements about the correlation coefficient, r .
a. the correlation coefficient is not affected by outliers.
b. the absolute value of r describes the magnitude of the association between two variables.
c. 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.
d. the value of r ranges from negative one to positive one.
e. if two variables are positively correlated, when one variable increases, the other variable decreases.
f. a correlation coefficient of zero means that no relationship exists between the two variables.
