The value of coefficient of range can never be 

The value of coefficient of range can never be  Correct Answer 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
