What is the least score and the greatest score of each golfer?
Golfer A Range: 15 strokes Golfer B Range: 8 strokes Comparison: The scores for Golfer A are more spread out.
Practice makes perfect
Consider the given scores for Golfer A and Golfer B.
Golfer A: & 83, 84, 91, 90, 98,
& 88, 95, 89, 87, 95 [0.5em]
Golfer B: & 89, 93, 92, 88, 89,
& 87, 95, 94, 91, 92
We are asked to find the range of the scores for each golfer. The range of a data set is the difference of the greatest value and the least value. Let's first order the given data.
Golfer A: & 83, 84, 87, 88, 89,
& 90, 91, 95, 95, 98 [0.5em]
Golfer B: & 87, 88, 89, 89, 91,
& 92, 92, 93, 94, 95
For Golfer A, we have that the least score is 83 and the greatest score is 98. For Golfer B, the least score is 87 and the greatest score is 95.
Let's calculate the range for each golfer.
Golfer A's Range:& 98- 83=15 strokes
Golfer B's Range:& 95- 87=8 strokes
The range for Golfer A is 15 strokes and for Golfer B is 8 strokes. Therefore, the scores for Golfer A are more spread out.
