Answer 1

If both ends of a group are taken in frequency grouping, it is called inclusive method.

Explanation:

In the inclusive method, both the upper and lower limits of a class interval are included (taken) within that same group. For example, in a class interval like 10–19, values of 10 and 19 are both counted in this group, and the next class begins at 20 (20–29). This classification method ensures that no values overlap between consecutive groups, making it highly effective for organising whole numbers or discrete data series.
