Make up a set of 10 pairs of scores (X and Y values) so that the Pearson correlation between X and Y is approximately r = 0.70. (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. (Note: Instructions for using the latest version of SPSS are contained in Appendix C.)
