A statistical survey is a method used to collect data from a specific group of people or items to understand trends, opinions, or behaviors. This process often involves asking questions through questionnaires or interviews, allowing researchers to gather quantitative and qualitative information. The results can help in making informed decisions or predictions about a larger population. Surveys can be conducted in various fields, including healthcare, marketing, and social sciences. They can be designed to be representative of a population, ensuring that the findings are reliable and applicable. Properly conducted surveys can provide valuable insights and support evidence-based conclusions.
