| Number of people | 3 | 5 | 1 | 1 | 2 | 3 |
Find the median age of the frequency distribution in the table above.
20
25
30
35
Explanation
Total freq = 15
Median position = \(\frac{n + 1}{2}\) for odd numbers
Median position = \(\frac{15 + 1}{2}\) = \(\frac{16}{2}\) = 8th position.
From the table, the 8th position corresponds to age 25.
