The correlation coefficient is
a unitless measure of the strength of the linear relationship
between two quantitative variables
a unitless measure of the strength of the linear relationship
between two categorical variables
measured in the same units as the larger quantitative
variable

A measure of the strength of the linear relationship that exists
between two variables is called: Slope/Intercept/Correlation
coefficient/Regression equation. If both variables X and Y increase
simultaneously, then the coefficient of correlation will be:
Positive/Negative/Zero/One. If the points on the scatter diagram
indicate that as one variable increases the other variable tends to
decrease the value of r will be: Perfect positive/Perfect
negative/Negative/Zero. The range of correlation coefficient is: -1
to +1/0 to 1/-∞ to +∞/0 to ∞. Which of...
