Which of the following are examples of the direct inquiry method of data collection?

The direct inquiry method of data collection refers to situations where data is collected through direct engagement with individuals, often through specific questions or structured interactions designed to gather information. Among the options provided, ordering food delivery via a smartphone app does not constitute a direct inquiry method because it typically involves transactional interactions without explicit questioning or data collection aimed at understanding user opinions or behaviors directly.

In contrast, registering an account for a new social media platform involves a user inputting personal information, but this is more about data collection through the process rather than a direct inquiry into individual experiences or opinions. Surveys filled out in person represent a clear example of direct inquiry, as they usually involve an interviewer asking questions directly to participants, gathering feedback or opinions in real-time. Similarly, interviewing a customer for feedback is a classic form of direct inquiry, where the interviewer actively seeks information through questions directed at the customer, allowing for deeper insights into their experiences and perspectives.

In summary, while ordering food delivery might involve data input and user engagement, it does not align with the characteristics of direct inquiry data collection methods, which focus on interactive questioning to obtain insights directly.
