To find median, let $\mathit{n}$ is number of numbers given. First arrange given numbers in ascending or descending order.
⇒ 12,12,13,14,16,18
Median $=\frac{{\left(\mathit{n}+1\right)}^{\mathrm{th}}}{2}$ term, if $\mathit{n}$ is odd.
$=\frac{1}{2}[{\left(\frac{\mathit{n}}{2}\right)}^{\mathrm{th}}.$ term $+{\left\{{\left(\frac{\mathit{n}}{2}\right)}^{\mathrm{th}}+1\right\}}^{\mathrm{th}}$ term $],$ if $\mathit{n}$ is even.
Here $\mathit{n}$ is even and equal to 6 .
Median $=\frac{1}{2}\left[13+14\right]\Rightarrow \frac{27}{2}$
Median $=13.5$
