Jillian and Dawn are playing a game of miniature golf. In this game, the score on a hole is the number of putts it takes to get the ball into the hole. The winner is the player with the lowest score. After playing 18 holes, Jillian’s mean is 2 point 4 and Dawn’s mean is 3 point 3 Which explains who won the game?
Answer
A
Dawn won the game because the person with the greater mean played better.
B
Jillian won the game because her score varied less than Dawn’s score.
C
Dawn won the game because her mean absolute deviation was less than Jillian’s.
D
Jillian won the game because the person with the lower mean took fewer putts on average for each hole.
Explanation
In miniature golf, a lower score means fewer putts and is better. Jillian’s mean was 2.4 putts per hole, while Dawn’s was 3.3, so Jillian took fewer putts on average and won. Choice D correctly explains the result; variation and mean absolute deviation do not determine which player had the lower average score.
