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
First, arrange the observations in ascending order:
1, 7, 13, 15, 18, 19, 23, 24, 28, 31, 32
Total number of observations = 11 (odd)
Median position
$\frac{n+1}{2} = \frac{11+1}{2} = 6$
The 6th observation is 19.
