Question

Then interquartile range is

• A. $1$
• B. $2$
• C. $10$
• D. $12$
• E. None

Answer 1

Answer: (B)

$2$

$X$

$3$

$5$

$12$

$3$

$2$

Arranging the terms in ascending order

$2,3,3,5,12$

$\Rightarrow 2,3,5,12$

Number terms are even.

So, the interquartile is ${\left(\frac{n}{4}\right)}^{th}$ term.

$\Rightarrow \left(\frac{4}{4}\right)$th term

$\Rightarrow 1^{st}$ term

So, the interquartile is $2$.

Hence, option $A$ is correct.
