<h3>What is a representative sample?</h3>
Representative samples are little amounts or components that are a part of a bigger group or organization. It shares the same characteristics as the bigger population it represents.
Consider a company in Germany's Bavaria that is going to launch a new service or product. It would be difficult for the company to poll every Bavarian to determine how they felt about the launch. As an alternative, researchers can compile a small sample from various locations in Bavaria that will serve as a representative sample of the local populace. After that, a survey will be given to the respondents to gather their comments on the good or service. A "representative sample" is the term used to describe this selection of Bavarian individuals.
