In a research study it is not always possible to measure an entire representing a specific demographic. (Some examples of demographics are students who attend a specific college, people who live in a specific city , state or neighborhood, people of a certain age range etc.).

The subjects from a sample population surveyed need to be randomly selected from a specific population of a specific demographic in order to be represented in an accurate manner.

Random Sampling- in the simplest terms means that each subject eligible to be in the study has an equal chance of being selected to be in the population under study. In this way the researcher can be more confident that the people in their sample are representative of the entire population of interest.
