Calculate the Median Age of the Frequency Distribution in the Table Above

(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

Correct Answer: Option A

Explanation

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
