Question
The monthly pocket money of 50 students of a class are given in the following distribution
| Monthly pocket money (in Rs) | 0 - 50 | 50 – 100 | 100 – 150 | 150 -200 | 200 – 250 | 250 - 300 |
| Number of Students | 2 | 7 | 8 | 30 | 12 | 1 |
Find the modal class and give class mark of the modal class.
Solution
Here the maximum class frequency is 30, and the class corresponding to the frequency is 150-200. So, the modal class is 150-200.
Also, class mark of the modal class is `(150+200)/2=175.`
