Questionnaire

A questionnaire is a structured set of questions used to gather information from individuals or groups. It's a common research tool employed in surveys, experiments, and assessments. Questionnaires can be administered in various formats, including paper-based forms, online surveys, and face-to-face interviews. They typically include a mix of question types, such as multiple-choice, open-ended, rating scales, and ranking questions, designed to elicit specific data. Careful design of a questionnaire is critical to ensure the questions are clear, unbiased, and relevant to the research objectives, minimizing potential for ambiguity or misinterpretation. Effective questionnaires produce reliable data. The purpose of a questionnaire is to collect data, feedback, or opinions from a specific audience, and the data can be used to identify trends, draw conclusions, or make informed decisions.
