Early in the correlation chapter the author showed figures in which he drew vertical and horizontal lines at the mean of each variable to cut the graph into four quadrants. When there is a high positive correlation between two variables, we would expect most of the data points to fall
a. to the right of vertical line.
b. in the upper right and lower left quadrants.
c. below the horizontal line.
d. equally in all four quadrants.
Question 2
The correlation between two variables is a measure of the degree to which
a. points cluster together around some best-fitting straight line.
b. differences in one variable can be predicted from differences in the other variable.
c. one variable varies with the other variable.
d. all of the above
