Answer 2

Modal Class --

When we are given a grouped data and we need to find the mode of that data, So here, we cannot simply find out the mode by just seeing that which is the most occurring value, then that will be our mode.
When we are given a grouped data, then to find the mode of that data, Modal class is required.
Basically, Modal class is the class interval corresponding to the highest frequency of the given data.

For an example, In the attachment, we can see that we are given some class intervals and there frequencies are also given.
So among all these class intervals, the modal class will be the class interval with highest frequency,
So here, we can say that 15-20 is the modal class because it is having the highest frequency which is 15.
