Closed questions are inquiries that can be answered with a simple "yes" or "no," or with a specific piece of information. They are designed to limit the response options, making it easier to gather clear and concise data. For example, asking, "Do you like chocolate?" requires a straightforward answer, which helps in situations where precise information is needed. These types of questions are commonly used in surveys, interviews, and research to obtain quantifiable results. They can help in assessing opinions, preferences, or factual information quickly. However, closed questions may not provide in-depth insights, as they restrict the respondent's ability to elaborate on their thoughts.
