The median of the observations 1, 13, 7, 19, 18, 15, 32, 28, 23, 24, 31 is:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 19
The median is the middle value once the observations are arranged in order. For \(n\) observations with \(n\) odd, it is the \(\frac{n+1}{2}\)th value.
In ascending order: 1, 7, 13, 15, 18, 19, 23, 24, 28, 31, 32
\(n=11\), so the median is the \(\frac{11+1}{2}=6\)th value
The 6th value is 19
