Not necessarily. Questionnaires can be written and administered in various formats and platforms, depending on the preferences of the researcher and the requirements of the study. While some questionnaires may be written directly on a physical or digital worksheet, others may be designed and administered through online platforms, email, phone interviews, or face-to-face interactions. The choice of format depends on factors such as the research objectives, target population, accessibility, and convenience for both the researcher and respondents.
