What is a written set of questions for a research participant called?

A written set of questions for a research participant is referred to as a questionnaire. This term specifically denotes a structured tool designed to gather information or data from respondents, typically in a systematic format. Questionnaires can consist of various question types, including open-ended and closed-ended questions, and are commonly used in both qualitative and quantitative research settings.

This tool is crucial in research because it enables researchers to collect consistent and comparable data from multiple participants. A well-designed questionnaire ensures that the information gathered is relevant and valuable for the research questions being studied.

In this context, while other terms like survey and quiz may seem similar, they have distinct meanings. A survey is generally a broader term that can include various methods of data collection, including questionnaires, interviews, and observational methods. A quiz, on the other hand, typically refers to a test of knowledge or skills, rather than a research tool. An application usually refers to a form used to request something, such as admission or a job, rather than a data collection instrument in a research setting. Therefore, "questionnaire" accurately captures the essence of what is being described.
