Question

The median of $19$ observations of a group is $30$. If two observations with values $8$ and $32$ are further included, then the median of the new group of $21$ observation will be

• A. $28$
• B. $30$
• C. $32$
• D. $34$

Answer 1

Answer: (B)

$30$

Clearly $8$ is less than the median and $32$ is more.

Thus, the order of the observation will be unchanged.

Hence, the median will remain same.
