Find median of the data:

13, 16, 12, 14, 19, 12, 14, 13, 14

Arranging the data in ascending order: 12, 12, 13, 13, 14, 14, 14, 16, 19

n = 9

∴ $\mathrm{Median}=\frac{\mathrm{n} + 1}{2}\mathrm{th} \mathrm{term} = \frac{9 + 1}{2}\mathrm{th} \mathrm{term} = \frac{10}{2} = 5\mathrm{th} \mathrm{Term}$

Median = value of 5th term

Median = 14.
