Survey design is the process of creating a set of questions and methodologies to gather data from a sample of individuals in order to gain insights and make inferences about a population or target group. It involves determining the purpose of the survey, selecting the appropriate survey method (such as online, phone, or in-person), designing the questions, choosing the sample size and sampling method, and analyzing the survey results. Survey design is an important research area that plays a crucial role in collecting accurate and reliable data for research studies, market research, opinion polls, and other data collection efforts. Techniques such as random sampling, question wording, and response options are key elements of survey design that can impact the validity and reliability of survey results.
