### Solution:

The series is first arranged into either ascending or descending order. The formula to calculate median

Of the series where $N$ is the number of observations in the series.
Arrange in ascending order
$N=6$
$\mathit{Median}={\frac{6+1}{2}}^{\mathit{th}}\mathit{term}={\frac{7}{2}}^{\mathit{th}}\mathit{term}=3.{5}^{\mathit{th}}\mathit{term}$

$=\frac{\left(6+8\right)}{2}=\frac{14}{2}=7$
