Correct Answer - Option 1 : Greater than or equal to 1
Explanation
Coefficient of range = (L - S)/(L + S)
Where as
L = Largest number
S = Smallest number
∴ The value of coefficient of range can never be equal or greater than 1
For example the range of the series 1, 2, 4, 6, 8, 9, 10, 12
Largest number = 12
Lowest number = 1
Range = L - S = 12 - 1 = 11
Coefficient of range = (L - S)/(L + S)
coefficient of this range = 11/13
∴ The coefficient of range is not equal or greater than 1
