Solution

The correct option is D average of n2 and n2+1
The observation that lies in the middle of a set of observations (after arranging in an ascending or descending order) is called the median of the data.

If the number of observations ‘n’ in a set of data is odd, then median is given by average of n2 and n2+1 values.
