Closed-ended questions are inquiries that can be answered with a simple "yes" or "no," or with a specific piece of information. They limit the respondent's answer options, making it easier to gather clear and concise data. For example, asking, "Do you like chocolate?" requires a straightforward response, which can be useful in surveys or research. These types of questions are often used in surveys, quizzes, and interviews to obtain quantifiable results. They help in quickly assessing opinions or facts without delving into detailed explanations. This format is particularly effective for statistical analysis and decision-making processes.
