The median of a set of $9$ distinctive observations is $20.5$. If each of the largest $4$ observations of the set is increased by $2$, then the median of the new set
🎥 Video solution / Text Solution of this question is given below:
For $9$ observations, median is the $5^{\text{th}}$ term. Increasing the top $4$ (positions $6$–$9$) does not change the $5^{\text{th}}$ value.
