What is the purpose of a survey study?

To conduct experiments on a controlled group
To observe changes in a specific variable
To gather information from a small group to generalize about the population
To establish a cause-effect relationship

The correct answer is: To gather information from a small group to generalize about the population

The purpose of a survey study is to gather information from a sample of individuals in order to make generalizations about a larger population. Survey studies typically involve collecting data through questionnaires or interviews that assess attitudes, opinions, or behaviors. By analyzing the responses from this selected group, researchers can infer trends and insights that may apply to the broader population. This method allows for the efficient collection of data from many individuals, enabling researchers to understand and quantify characteristics of the population without needing to engage every individual directly. This approach is particularly valuable in fields such as social sciences, marketing, and public health, where understanding the perspectives of a target population is crucial for decision-making and policy development.
