The monthly pocket money of 50 students of a class are given in the following distribution:

$\begin{matrix} M o n t h l y p o c k e t m o n e y (i n R s .) & 0 - 50 & 50 - 100 & 100 - 150 & 150 - 200 & 200 - 250 & 250 - 300 N u m b e r o f s t u d e n t s & 2 & 7 & 8 & 30 & 12 & 1 \end{matrix}$

Find the modal class and also give class mark of the modal class.

Solution

As we know the class with maximum frequency is called modal class. Hence, the modal class in the above question is 150-200 as it has the highest frequency of 30.
Hence the class mark is: $\frac{150 + 200}{2}$ = 175
