Question

If in a data, $10$ numbers are arranged in increasing order. If the $7th$ entry is increased by $4$, then the median increase by

• A. $0$
• B. $4$
• C. $6$
• D. Cannot be determined

Answer 1

The correct option is A $0$

The median of $10$ numbers will be the mean of $5^{th}$ and $6^{th}$ terms.

If the $7^{th}$ term is increased, it will not have any affect in the median as the $5^{th}$ and $6^{th}$ terms will remain unchanged.

So, the median increases by $0$.
