Questionnaire

A questionnaire is like a piece of paper with lots of questions on it that people can answer. You might have seen a form with questions on it at a doctor's office or at school. Parents, teachers, doctors, or researchers use questionnaires to ask people about their experiences, opinions, or behavior. Answering questions may help people share how they feel or what they think so that others can better understand them. A questionnaire may also help collect data or information that can be used to make decisions. It's important to read the questions carefully and answer them truthfully because that way the answers can be as helpful as possible.
