Quizplus · Accepted Answer

The two common types of research instruments used to collect primary data are questionnaires and mechanical devices. Questionnaires are self-administered written instruments that ask respondents for information about themselves or their opinions. Mechanical devices include tools such as cameras, heart rate monitors, and eye-tracking devices that can provide objective data without relying on self-reporting. Surveys and samples (A) are methods of selecting respondents rather than instruments for data collection. Focus groups and online databases (C) and online panels and experiments (D) are also methods of data collection, but they are not as commonly used as questionnaires and mechanical devices. Personal interviews and online focus groups (E) are also methods of data collection, but they are not types of research instruments.
