The marks obtained by 13 students in an examination are 15, 25, 32, 44, 24, 18, 54, 42, 58, 15, 80, 22 and 40. Find the median.
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 32
The median is the middle value after arranging the data in order. For an odd number \(n\) of values, it is the \(\displaystyle\frac{n+1}{2}\)th value.
In ascending order: 15, 15, 18, 22, 24, 25, 32, 40, 42, 44, 54, 58, 80
\(n=13\), so the median is the \(\displaystyle\frac{13+1}{2}=7\)th value
The 7th value is 32
The median is 32.
