What is the median class for the data?

$\begin{matrix} C l a s s i n t e r v a l & f r e q u e n c y 0 - 10 & 7 10 - 20 & 13 20 - 30 & 14 30 - 40 & 5 40 - 50 & 11 \end{matrix}$ [2 MARKS]

Concept: 2 Marks

Since there are a total of 50 observations, the median class is the one whose cumulative frequency is closest to and greater than 25.

$\begin{matrix} C l a s s i n t e r v a l & f r e q u e n c y & C F 0 - 10 & 7 & 7 10 - 20 & 13 & 20 20 - 30 & 14 & 34 30 - 40 & 5 & 39 40 - 50 & 11 & 50 \end{matrix}$

Thus, the class interval 20-30 is the required answer.
