Question

Write the formula of co-efficient of range and find its range.

Answer 1

Coefficient of range = $\left(\frac{L-S}{L+S}\right)$

Where, L is the highest value of given data.

S is the smallest value of given data.

Since, L – S is always positive, the ratio of difference of two terms to the sum of two terms is always less than 1.

Hence, its range lies between 0 and 1.
