A Better Golf Tee? An independent golf equipment testing facility compared the difference in the performance of golf balls hit off a regular 2-3/4 wooden tee to those hit off a 3 Stinger Competition golf tee. A Callaway Great Big Bertha driver with 10 degrees of loft was used for the test, and a robot swung the club head at approximately 95 miles per hour. Boxplots of the distances traveled, in yards, are shown in the following figure. Use the boxplots to compare the driving distances for the two golf tees, paying special attention to center and variation.
