Question

If $1,2,3,4,5,6,7$ are numbers then $Q_1$ and $Q_2$ are respectively

• A. $2,4$
• B. $2.6$
• C. $4,6$
• D. $3,5$

Answer 1

Answer: (A)

$2,4$

The given observations are,

$1,2,3,4,5,6,7$

Number of observations $=7$

$Q_i={\{i.\left(\frac{N+1}{4}\right)\}}^{th}term$

$Q_1={\left\{1.\left(\frac{7+1}{4}\right)\right\}}^{th}term$

$Q_1=2^{nd}term$

$\therefore$ $Q_1=2$

$Q_2={\left\{2.\left(\frac{7+1}{4}\right)\right\}}^{th}term$

$Q_2=4^{th}term$

$\therefore$ $Q_2=4$
