Question

If the number of observations ‘n’ in a set of data is even, then the median value is given by ____.

• A. $\frac{n+2}{2}$
• B. average of $\frac{n}{2}$ and $\frac{n}{2}+1$
• C. $\frac{n+1}{2}$
• D. $\frac{n}{2}$

Answer 1

Answer: (B)

average of $\frac{n}{2}$ and $\frac{n}{2}+1$
he 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.

f the number of observations ‘n’ in a set of data is odd, then median is given by average of $\frac{n}{2}$ and $\frac{n}{2}+1$ values.
