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
The correct answer is: 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
