Co-efficient of Quartile deviation
= (Q3-Q1)/(Q3+Q1)
= (20-10)/(20+10)
= 10/30
= 1/3 or 0.3333

The coefficient of quartile deviation = 1/3

Given :

Q₃ = 20 & Q₁ = 10

To find :

The coefficient of quartile deviation

Solution :

Step 1 of 2 :

Write down the given quartile

By the given

First quartile = Q₁ = 10

Third quartile = Q₃ = 20

Step 2 of 2 :

Find coefficient of quartile deviation

The coefficient of quartile deviation

\displaystyle \sf{   =  \frac{Q_3 -Q_1 }{Q_3 + Q_1} }

\displaystyle \sf{   =  \frac{20 - 10 }{20 + 10} }

\displaystyle \sf{   =  \frac{10 }{30} }

\displaystyle \sf{   =  \frac{1 }{3} }
