Question

Find the median of the following data. Class Intervals 0-10 10-20 10-20 20-30 30-40 40-50 50-60 .Frequency 8 15 19 25 20 13 . ​

Answer 1

Median (If even no. of observations)

$\begin{gathered}\\ \tt{:}\dashrightarrow [\frac{(n+1)}{2}]^{th}\:term\end{gathered}$

• N is the no. of observations.
• Here number of observations or number of frequencies is 6.

$\begin{gathered}\\ \sf\longmapsto [\frac{(6+1)}{2}]^{th}\:term\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 3+1^{th}\:term\end{gathered}$

$\large\color{gold}{ \tt{4^{th}\:term}}$

Hence, The median of the given observation is 25.
