Mathematics marks of 5 students are given below:

20, 35, 25, 30, 10

Find out range and coefficient of range.

Open in App

Solution

Here, L = Largest value, S = Smallest value,

L = 15, S = 35 Range = L - S

Range = 35 - 15 = 20

Coefficient of Range = $\frac{L - S}{L + S}$

$= \frac{35 - 15}{35 + 15}$ $= \frac{20}{50} = 0.4$
