Question 12.
While preparing a frequency distribution, your friend is confused about inclusive and exclusive classes. Help her to distinguish between them, with examples for each. (March 2013)
Answer:
Inclusive Method
In comparison to the exclusive method, the Inclusive Method does not exclude the upper-class limit in a class interval. It includes the upper class in a class. Thus both class limits are parts of the class interval. An example of the inclusive method of a frequency distribution is given below.

Exclusive Method
The classes, by this method, are formed in such a way that the upper-class limit of one class equals the lower class limit of the next class. In this way, the continuity of the data is maintained. That is why this method of classification is most suitable in the case of data of a continuous variable. Under the method, the upper-class limits excluded but the lower class limit of a class is included in the interval.
