Survey design is the process of creating a structured questionnaire to collect information from a specific group of people. It involves defining the objectives of the survey, selecting the target population, and determining the types of questions to ask. Good survey design ensures that the questions are clear, unbiased, and relevant to the research goals. Effective survey design also considers the method of data collection, such as online surveys, phone interviews, or face-to-face interactions. Additionally, it includes planning for data analysis and interpretation, ensuring that the results can provide meaningful insights into the target population and the research objectives.
