Question

Explain/Define the following concept.
Exclusive method.

Answer 1

Hint: In this problem, we can see about the exclusive method and its explanation with examples. We should know that an exclusive method is used in statistical problems, where graphs are based on variations and are used for data of continuous variables. We should know that the exclusive method is used for those series in which the upper limit of one class becomes the lower limit of the next class. We can now see about it with an example.

Complete step by step answer:
Here we can see an exclusive method.
We know that the exclusive method is used for those series in which the upper limit of one class becomes the lower limit of the next class.
We can also say it is exclusive when the frequencies of the upper limit of a class interval are not included in the particular class. In such a type of series, the upper limit of one class becomes the lower limit of the next class.
For example, 0-10, 10-20, 20-30, ….
Here we can see that the upper limit of one class becomes the lower limit of the next class, where the upper limit is excluded but the lower limit is included in the class interval.

We can also say it is exclusive when the frequencies of the upper limit of a class interval are not included in the particular class.
