Q. 25 - Elementary Statistics

Question

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.

Step-by-Step Solution

Answer

Driving distance of Regular golf tees is less than Stinger golf tees.

Step 1: Given information

We need to find out the variation of distance traveled by regular and stinger golf tees.

Step 2: Explanation

The whiskers of the boxplot are of low and high value. The box starts at the lower quartile, ends at the upper quartile, and has a straight vertical line at the median.

In general, both groups seem to lose almost the same amount as the median is almost identical in both groups

Now, the distance traveled by regular golf tees is slightly lower than distance traveled by stinger golf tees.
