What term denotes a number of people who are representative of a study's population?

• A. Sample
• B. Public recreation
• C. Public relations
• D. Publicity

Answer: (A)

In research, a subset of individuals chosen to represent the larger group is called a sample. This allows researchers to gather information, make inferences about the whole population, and do so efficiently without surveying everyone. A good sample mirrors the population’s key characteristics, and methods like random or stratified sampling help ensure this representativeness. The other terms—public recreation, public relations, and publicity—relate to services or communications and have nothing to do with selecting participants for a study. So the term denoting a number of people representative of the study’s population is a sample.
