The following data give the resting pulse rates (in beats per minute) and the years of schooling of 10 individuals. A scatter diagram of these data is presented in Figure 2.15. The sample correlation coefficient for these data is r =−.7638. This negative correlation indicates that for this data set a high pulse rate is strongly associated with a small number of years in school, and a low pulse rate with a large number of years in school.
