(Hint: Sketch a scatter plot similar to the one shown in Figure 15.6 showing a pattern that corresponds to a reasonably good, positive correlation. Then add numbers to both axes and read the X and Y values from your graph.) If you have access to SPSS or a similar data analysis program, calculate the Pearson correlation for your scores.
