The two main types of research instruments used to collect primary data are questionnaires and mechanical devices. Questionnaires can be administered in person, over the phone, by mail, or online, and can include open-ended or closed-ended questions. Mechanical devices can include things like sensors, cameras, and tracking systems, and are used to collect data automatically without the need for human interaction. Other options listed, such as official records and samples, focus groups, online databases, online panels, personal interviews, and online focus groups, are also used to collect primary data but are not the two main types of research instruments.
