Explanation:
A questionnaire is a written data collection instrument consisting of a series of questions or statements to which respondents provide answers in writing. It is widely used in educational, social, and psychological research due to its efficiency and ability to collect data from a large number of respondents.
Questionnaires may include open-ended or close-ended questions and can be administered in person, by mail, or online. They ensure uniformity, reduce researcher bias, and allow respondents to answer at their convenience. In contrast, interviews involve oral responses, and observation sheets record behaviors.
In educational research, questionnaires are commonly used to study attitudes, opinions, teaching effectiveness, and institutional performance. PPSC often tests research tools because they are fundamental components of research methodology.
