Research question
A research question is the focused, answerable question that a study sets out to address — the anchor that guides its design, methods and analysis.
The step most authors miss
Doing CRediT right? Don’t stop at the statement.
A CRediT statement credits you inside one paper. The recognition CRediT was built for happens when those roles are tied to you, persistently. Sign in with your ORCID — free — and claim your CRediT contributions on casrai.org, the home of the standard. They become a verified, portable part of your identity, not a line that disappears into one PDF.
Free: claim your contributions, then export a journal-ready CRediT statement, schema.org structured data, JATS XML, CSV or BibTeX — and preview your public profile. A membership publishes that profile publicly and verifies the journals you serve.
What makes a research question strong
A research question is the engine of a study: get it right and the design follows; get it wrong and no amount of good method will rescue the project. A strong question is focused enough to be answerable in a single study rather than sprawling across a whole field, clear enough that its terms are unambiguous, and complex enough to require genuine investigation rather than a yes/no fact-check. It must also be feasible — answerable with the time, data, access and skills available — and significant, addressing something that matters to the field. Questions that are too broad (“What causes poverty?”) or too trivial cannot anchor a viable study; narrowing and sharpening the question is usually the most valuable early work.
The FINER framework
FINER is a widely used checklist for appraising a research question, asking whether it is Feasible, Interesting, Novel, Ethical and Relevant. Feasible means it can realistically be answered with available participants, expertise, time and funding. Interesting means it matters to you and to the field. Novel means it confirms, extends or challenges existing knowledge rather than merely repeating it. Ethical means it can be investigated without harm and with appropriate approval. Relevant means the answer would matter — to practice, policy, or future research. Running a draft question through FINER quickly exposes whether it is worth pursuing or needs reshaping.
The PICO framework
In clinical, health and intervention research, PICO is the standard tool for structuring a question. It identifies the Population (who is being studied), the Intervention (what is being done or examined), the Comparison (the alternative it is measured against, such as a placebo or standard care), and the Outcome (what is measured to judge effect). Specifying these four elements turns a vague interest into a precise, searchable question — for example, “In adults with insomnia (P), does cognitive behavioural therapy (I) compared with sleep medication (C) improve sleep quality (O)?” PICO is especially useful for evidence-based practice and for building literature-search strategies, though it suits comparative quantitative questions better than open qualitative enquiry.
Aims, objectives and scope
A research question sits within a small hierarchy. The aim is the broad purpose of the study; the objectives are the specific, measurable steps that achieve it; and the research question (or questions) express what must be answered to meet them. Keeping these aligned prevents drift — every objective should serve the aim, and every question should map onto an objective. Scope is the deliberate boundary you draw around the study: the population, setting, timeframe and aspects included, and, just as importantly, those excluded. Stating scope explicitly keeps the question feasible and tells readers what the study does and does not claim to address, which is essential for interpreting its findings fairly.

Common questions
FAQ
What is the FINER framework?+
FINER is a checklist for judging whether a research question is worth pursuing. It asks whether the question is Feasible (answerable with available resources), Interesting (to you and the field), Novel (adding to existing knowledge), Ethical (investigable without harm) and Relevant (its answer would matter). Running a draft question through FINER quickly shows whether it is sound or needs reshaping.
What is the difference between a research question and a hypothesis?+
A research question asks what you want to find out, while a hypothesis predicts the answer. Exploratory and qualitative studies often proceed from questions alone, whereas hypothesis-driven studies turn the question into a testable, falsifiable prediction about the relationship between variables. In many quantitative studies the question comes first and the hypothesis is derived from it.
What is the difference between an aim and a research question?+
An aim is the broad purpose of the study — what you ultimately want to achieve — while a research question is the specific, answerable question that, once answered, helps fulfil that aim. A study usually has one aim, several measurable objectives, and one or more research questions mapped onto those objectives, keeping the whole project aligned.
