The median of the observations 1, 13, 7, 19, 18, 15, 32, 28, 23, 24, 31 is: |
18 19 23 24 |
19 |
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. |
