Question

Find the mode of the following data.

$\begin{matrix} C l a s s i n t e r v a l & 0 - 100 & 100 - 200 & 200 - 300 & 300 - 400 & 400 - 500 F r e q u e n c y & 7 & 11 & 15 & 9 & 8 \end{matrix}$

___

Solution

Modal Class is 200-300

Mode=I+ $(\frac{f_{1} - f_{0}}{2 f_{1} - f_{0} - f_{2}})$ $\times$ h

=200+ $\frac{15 - 11}{30 - 11 - 9}$ $\times$ 100=240
