Use a statistical spreadsheet or a graphing calculator with advanced statistical features to draw a scatter diagram of the data in Table 1. Then determine the linear correlation between club-head speed and distance.

Approach We will use Excel to draw the scatter diagram and obtain the linear correlation coefficient. The steps for drawing scatter diagrams and obtaining the linear correlation coefficient using the TI-83/84 Plus graphing calculators, Minitab, Excel, and StatCrunch are given in the Technology Step-by-Step.
