The table shows the ages(in years) of twenty children chosen at random from a community. What is the median of the distribution? \(\begin{array}{c|c} Age(years) & 1 & 2 & 3 & 4 & 5 \\ \hline {\text {Number of children}} & 2 & 3 & 5 & 6 & 4 \end{array}\)
A. 3.5 years B. 3.0 years C. 2.5 years D. 2.0 years
Correct Answer: A
Explanation
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
