Question

Find the mode of the following data.

$\begin{matrix} N u m b e r o f P l a n t s & 0 - 2 & 2 - 4 & 4 - 6 & 6 - 8 & 8 - 10 & 10 - 12 & 12 - 14 N u m b e r & 1 & 3 & 2 & 4 & 5 & 3 & 2 \end{matrix}$

Solution

The modal Class is 8-10 with the highest frequency of 5

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

=8+ $\frac{5 - 4}{10 - 4 - 3}$ $\times$ 2 = 8.67
