Heights of 50 students of class X of a school are recorded and following data is obtained: Find the median height of the students.

Class	\(\displaystyle f\)	\(\displaystyle c f\)
$\displaystyle 130$-$\displaystyle 135$	$\displaystyle 4$	$\displaystyle 4$
$\displaystyle 135$-$\displaystyle 140$	$\displaystyle 11$	$\displaystyle 15$
$\displaystyle 140$-$\displaystyle 145$	$\displaystyle 12$	$\displaystyle 27$
$\displaystyle 145$-$\displaystyle 150$	$\displaystyle 7$	$\displaystyle 34$
$\displaystyle 150$-$\displaystyle 155$	$\displaystyle 10$	$\displaystyle 44$
$\displaystyle 155$-$\displaystyle 160$	$\displaystyle 6$	\(\displaystyle 50=N\)

Median class is $\displaystyle 140$-$\displaystyle 145$ \[\begin{aligned} \text { Median } & =140+\frac{5}{12}(25-15) \\ & =144 \cdot 1 \text { (approx) } \end{aligned} \]Hence, Median height is 144.1cm
