Mean of the first golfer = 89
Mean of the second golfer = 87
Range of the first golfer = 11
Range of the second golfer = 8
Explanation:
First golfer scores 88, 90, 86, 89, 96 and 85.
Sum of the scores of first golfer = 88 + 90 + 86 + 89 + 96 + 85 = 534
Number of observation of first golfer = 6
Mean of the first golfer =
Mean of the first golfer = 89
Range of the first golfer = Highest score – Lowest score
= 96 – 85
Range of the first golfer = 11
Second golfer scores 91, 86, 88, 84, 90 and 83.
Sum of the scores of second golfer = 91 + 86 + 88 + 84 + 90 + 83 = 522
Number of observation of second golfer = 6
Mean of the second golfer =
Mean of the second golfer = 87
Range of the second golfer = Highest score – Lowest score
= 91 – 83
Range of the second golfer = 8
Comparing the golfer's skills:
Mean of first golfer is greater than Mean of second golfer. (i.e. 89 > 87)
Range of first golfer is greater than Range of second golfer. (i.e. 11 > 8)
Thus, first golfer have more skills than second golfer.
