Calculate the median age of the frequency distribution in the table above
A
25
B
30
C
35
D
20
Verified Correct Answer: A.
Step-by-Step Mathematical Solution
N = \(\sum f\) = 15
Hence 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
