Description: A questionnaire is a set of questions designed to gather information from respondents. This instrument is used in various disciplines, such as social research, education, and product development, to obtain qualitative and quantitative data. Questionnaires can be administered in person, by mail, by phone, or online, making them a versatile and accessible tool. Their design can vary from closed questions, which offer limited response options, to open questions, which allow respondents to express their opinions more freely. The clarity and relevance of the questions are fundamental to ensuring the validity of the collected data. Additionally, questionnaires can be anonymous, encouraging honesty in responses, and can be used to assess attitudes, behaviors, knowledge, and experiences. In the context of user experience and market research, questionnaires are essential for understanding user needs and expectations, facilitating informed decision-making and continuous improvement of products and services.
