2. Questionnaire Design: The questions must be clear, concise, and relevant to the objectives of the survey.
3. Data Collection Methods: Methods can include face-to-face interviews, telephone surveys, online questionnaires, and mailed surveys.
4. Data Analysis: Statistical techniques are employed to analyze the data and make inferences about the population.
5. Ethical Considerations: Ensuring informed consent, confidentiality, and the right to withdraw are fundamental ethical concerns.
