The correct answer is:
$0.75$
$\begin{aligned} & N=48 \\ & \frac{N}{2}=24\end{aligned}$
$\therefore$ Median $=24$ th observation $=12$
$\begin{aligned} N & =48 \\ \mathrm{MD} & =\frac{\Sigma f_i\left|x_i-M\right|}{N}=\frac{36}{48}=0.75\end{aligned}$
$\therefore$ Median $=24$ th observation $=12$
$\begin{aligned} N & =48 \\ \mathrm{MD} & =\frac{\Sigma f_i\left|x_i-M\right|}{N}=\frac{36}{48}=0.75\end{aligned}$
