Find the coefficient of range for the following data.
Size $10 - 15$ $15 - 20$ $20 - 25$ $25 - 30$
Frequency $2$ $4$ $6$ $8$

Open in App

Solution

Largest value $(L) = 30$
Smalles value $(S) = 10$
Therefore,
Coefficient of range $= \frac{L - S}{L + S} = \frac{30 - 10}{30 + 10} = \frac{20}{40} = \frac{1}{2} = 0.5$
