Question

s developed a method for ranking the total driving performance of golfers. The method requires knowing a golfer's average (yards) and driving accuracy (percent of drives that land in the fairway). The values of these two variables are used to driving compute a driving performance index. Twenty driving performance index observations are listed in the table below. Use this information to complete parts a through c. 1.44 3.34 1.93 1.41 1.31 2.02 2.71 2.13 2.28 2.15 1.41 1.32 1.35 2.64 2.29 1.41 1.35 1.75 2.24 3.51 a. Find the mean, median, and mode for the 20 driving performance index values. What is the mean? x 1.999 (Round to three decimal places as needed.) What is the median? median (Round to three decimal places as needed.)

Explanation / Answer

Using R software:

x <- c(1.35,2.64,1.44,1.93,1.31,1.41,1.75,2.71,2.28,1.41,
3.51,2.29,3.34,1.41,2.02,1.35,2.24,2.13,2.15,1.32)

round( mean(x),3)

mean=2.000

round(median(x),3)

median=1.975
