Median of the data 10, 20, 15, 5, 25 is?

Concept: The median is one of three measures of central tendency used in statistics. The value of the middle-most observation obtained after organising the data in ascending order is the data's median.

Given: 10, 20, 15, 5, 25

Here, total number of observations are in odd number. Therefore, median is given by:

$\Rightarrow \text{Median\hspace{0.17em}=\hspace{0.17em}}{\left[\frac{\left(n+1\right)}{2}\right]}^{th}term$

Here, number of observation n = 5

$\begin{array}{l}\Rightarrow \text{Median\hspace{0.17em}=\hspace{0.17em}}{\left[\frac{5+1}{2}\right]}^{th}term\\ \Rightarrow {\left[\frac{6}{2}\right]}^{th}term\\ \Rightarrow 3^{rd}term\end{array}$

Here, third term is 15, so median is 15.
