83, 80, 88, 86, 81, 84, 87.
Find which golfer may be considered to be a more consistent player ?​

Answer 1

Golfer A has less range hence more consistent

Step-by-step explanation:

Golfer A:  

74, 75, 78, 78, 72, 77, 79, 78, 81, 76, 72, 72, 77, 74, 70, 78, 79, 80, 81,.74, 80. 75. 71, 73.

Minimum = 70

Maximum = 81

Range = 81 - 70 = 11

Golfer B:

86, 84, 80, 88, 89, 85, 86, 82, 82, 79, 86, 80, 82, 76, 86, 89, 87, 83, 80, 88, 86, 81, 84, 87.

Minimum = 76

Maximum =  89

Range = 89 - 76 = 13

Golfer A has less range hence more consistent

Answer 2

Given: Golfer A: $74,75,78,78,72,77,79,78,81,76,72,72,77,74,70,78,79,80,81,74,80,75,71,73$.

            Golfer B: $86, 84, 80, 88, 89, 85, 86, 82, 82, 79, 86, 80, 82, 76, 86, 89, 87,83, 80, 88, 86, 81, 84, 87$.

To Find: Which golfer may be considered to be a more consistent player.

Step-by-step explanation:

• First check out the maximum and minimum score of Golfer-A,

Maximum score of Golfer-A is $81$

Minimum score of Golfer-A is $70$

Range of Golfer-A is $(81-70)=11$__1

• Then check out the maximum and minimum score of Golfer-B,

Maximum score of Golfer-B is $89$

Minimum score of Golfer-B is $76$

Range of Golfer-B is $(89-76)=13$__2

So, Which Golfer is less Range his Consistent is more.

From equation-1 & 2, We can seen that Golfer-A is less Range.

So,

    Golfer-A considered to be a more consistent player.
