Question

Find the median of the data :

$5.4,2.7,3.8,7.9,8,4,10,4.6,6.2$

Answer 1

Step 1 : Arrange the data in ascending order .

$\Rightarrow 2.7,3.8,4,4.6,5.4,6.2,7.9,8,10.$

Step 2 : Calculate the $\left(\frac{n+1}{2}\right)$th observation to calculate median .

$$\begin{gathered} \Rightarrow \frac{9+1}{2} \\ \Rightarrow \frac{10}{2}\Rightarrow 5thobservation \end{gathered}$$

5th observation $=5.4$

Hence, the median of the given data is $5.4$.
