Question

If the first and third quartiles are 22.16 and 56.36 respectively, then the quartile deviation is

Answer 1

Answer:

Quartile Deviation is 17.1

Step-by-step explanation:

Given:

First Quartile, $Q_1$ = 22.16

Third Quartile, $Q_3$ = 56.36

To find: Quartile Deviation

We know that,

$Quartile\:Deviation\,/\,Inter\:Quartile\:Range=\frac{Third\:Quartile-First\:Quartile}{2}=\frac{Q_3-Q_1}{2}$

So, here

$Quartile\:Deviation=\frac{56.36-22.16}{2}=\frac{34.2}{2}=17.1$

Therefore, Quartile Deviation is 17.1
