**MCQs on Sampling in Research Methodology**: Answers are given along with the multiple-choice questions.

**Sampling:** In simple terms, a sample is a part of a thing (generally known as population) and it has the ability to display the qualities and features of the thing, of which it is a part. Whereas Sampling is the process of selecting samples from the entire population.

12 Why are sampling traits important in sampling?

They help us in deciding the sample size.

They help us to differentiate between useless units and useful units.
