The three terms that best describe characteristics of appropriate research questions are:
- Answerable - A good research question should be able to be answered through data collection and analysis.
- Focused - A well-defined research question should be specific enough to guide the research process and not too broad or vague.
- Relevant - The research question should be pertinent to the field of study and contribute to existing knowledge or address a particular issue.
The terms "general" and "reliable" do not accurately describe characteristics of appropriate research questions in this context.
