The table shows the ages(in years) of twenty children chosen at random from a community. What is the median of the distribution? $\begin{array}{c|c} Age(years) & 1 & 2 & 3 & 4 & 5 \\ \hline {\text {Number of children}} & 2 & 3 & 5 & 6 & 4 \end{array}$

3.5 years

3.0 years

2.5 years

2.0 years

Correct answer is A

Median = ( $\frac{n + 1}{2})^{th}$

= $\frac{20 + 1}{2} = \frac{21}{2}$

= 10.5

= $\frac{{\text{10th term and 11th term}}}{2}$

= $\frac{3 + 4}{2} = \frac{7}{2}$

= 3.5yrs
