For the given frequency
distribution, what is the modal class?
If we have a look at the table we
are given, we could observe that in this frequency distribution, we have
classes. For example, the first class zero
dash would indicate values which are zero or greater up to but not including 10. In this question, we need to find
the modal class. The modal class is like the
mode. The modal class of a grouped
frequency distribution is the class or classes with the highest frequency. We can identify that the highest
frequency here is 12, and this occurs in the class 30 dash. It is this class which will be the
answer for the modal class.
We must be very careful because
it’s a very common mistake to give the answer of 12. But the value of 12 means that 12
individual data points exist in the class of 30 dash. And this is higher than the number
of data points in the other classes. The modal class is 30 dash.
