The formula for the coefficient of range is Range/a+b. Here, a and b denote

Explanation:

As we know that, Range is the difference between minimum and maximum value of data set.

Let,

a be the maximum value of the data set

b be the minimum value of the data set

Range = a -b

Co-efficient of Range

 = a-b/a+b OR Range/a+b.

Final Answer:

Hence, Option (B) is correct. As, a and b denotes the maximum and the minimum value of the data set.
