\(\begin{array}{c|c}Age & 20 & 25 & 30 & 35 & 40 & 45 \\
\hline \text{No. of people} & 3 & 5 & 1 & 1 & 2 & 3 \end{array}\)
Calculate the median age of the frequency distribution in the table above
-
25
- 30
- 35
- 20
The correct answer is: A
Explanation
N = \(\sum f\) = 15Hence the median age is the \(\frac{N + 1}{2}\)th age, i.e.
\(\frac{15 + 1}{2}\)th = 8th
From the table, the age that falls on the 8th position when arranged in ascending order is 25years
