The heights (in cm) of 9 students of a class are as follows:
155, 160, 144, 149, 150, 147, 152, 144, 148
Find the median height (in cm).
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 149
The median is the middle value once the data are arranged in order. With an odd number of values \(n\), it is the \(\frac{n+1}{2}\)th value.
In ascending order: 144, 144, 147, 148, 149, 150, 152, 155, 160
\(n=9\), so the median is the \(\frac{9+1}{2}=5\)th value
The 5th value is 149
