Question

If the median of $25$ observations is $45$ and if the observations greater than the median is increased by $4$, then the median of the new data is

• A. $49$
• B. $41$
• C. $45$
• D. None of these

Answer 1

The correct option is C $45$

As the median is the positional average and by adding $4$ to each observation greater than the median the positions of the values are unchanged.
Hence, the median remains same.
