Question

in which data - set does the range have the greatest measure of spread?
a 17, 34, 45, 56, 99
b 16, 42, 54, 67, 78
c 54, 76, 89, 91, 98
d 100, 16, 45, 61, 79

Explanation:

Step1: Recall range formula

Range = Maximum - Minimum

Step2: Calculate range for Option A

Maximum = 73, Minimum = 34, Range = 73 - 34 = 39

Step3: Calculate range for Option B

Maximum = 70, Minimum = 42, Range = 70 - 42 = 28

Step4: Calculate range for Option C

Maximum = 81, Minimum = 30, Range = 81 - 30 = 51

Step5: Calculate range for Option D

Maximum = 90, Minimum = 15, Range = 90 - 15 = 75

Answer:

D. 90, 15, 48, 61, 75
