Quizplus · Accepted Answer

The two main types of research instruments used to collect primary data are questionnaires and mechanical devices. Questionnaires involve asking people to respond to a series of questions, while mechanical devices involve using technology to collect data, such as through monitoring and tracking devices. Surveys, samples, online panels, experiments, focus groups, and online databases may all be used in conjunction with these two main instruments, but they are not the primary instruments themselves. Personal interviews may also be a primary instrument, but they are typically categorized under questionnaires.
