Research does not have to use statistics. Qualitative research can stand on its own when the question calls for systematic investigation of meanings, experiences, processes, practices, or contexts rather than numerical estimation.
Read Guide →There is no single sequence of scientific-method steps that every researcher must follow. Scientific inquiry uses diverse methods, but those methods remain accountable to shared principles concerning evidence, reasoning, transparency, and scrutiny.
Read Guide →Systematic research follows an organized and defensible process, while rigorous research applies appropriate methods with sufficient care to support credible conclusions. Neither requires one universal procedure.
Read Guide →Empirical research develops or evaluates knowledge through systematic engagement with observation or experience. It can be quantitative or qualitative, but not every legitimate form of scholarly research is empirical in the same sense.
Read Guide →Objectivity is an important research value, but it does not require researchers to become perspective-free observers. Strong research uses methodological safeguards, transparency, critical scrutiny, and, where appropriate, reflexivity to reduce or account for influences that could distort conclusions.
Read Guide →Anecdotes and expert opinions can be informative, but they are not equivalent to systematically produced research evidence. Their value depends on the question, while research provides methods for examining claims beyond individual experiences or authority.
Read Guide →Market research and academic research can use many of the same systematic methods. Their main differences usually concern purpose, audience, constraints, dissemination, and how the resulting knowledge is expected to be used.
Read Guide →Reading and summarizing previous studies is essential to research, but it does not automatically constitute a research study. A literature review becomes research when existing evidence is itself investigated systematically to answer a defined question using a defensible review methodology.
Read Guide →Research does not become rigorous simply by following the method most familiar in a discipline. Rigor depends more fundamentally on whether the research design fits the question and is conducted, analyzed, and reported according to appropriate standards.
Read Guide →Research does not always need to produce a solution to a practical problem. Some research is valuable because it improves understanding, develops explanations, or provides knowledge that later work can build upon.
Read Guide →Research does not always need to explain why something happens. Careful description can constitute a meaningful research contribution when it systematically establishes what exists, occurs, varies, or is experienced.
Read Guide →Scientific research does not have to manipulate variables or conduct experiments. Observational and other nonexperimental approaches can produce rigorous scientific evidence when they appropriately address the research question.
Read Guide →Scientific research does not have to be quantitative. Qualitative research can produce rigorous and defensible knowledge when its questions, evidence, methods, analysis, and conclusions are appropriately aligned.
Read Guide →Rigorous research does not need to be highly complex. A focused question, appropriate design, careful execution, transparent reasoning, and conclusions that match the evidence may matter far more than methodological complication.
Read Guide →A simple study can be stronger than a technically complicated one. What matters is whether the design produces credible evidence for the question, not how many methodological features it contains.
Read Guide →Research does not simply collect facts and turn them into knowledge. It produces knowledge by systematically connecting questions, observations, evidence, reasoning, and conclusions that can be scrutinized and revised.
Read Guide →Research is a systematic process of investigation, while evidence is information that bears on a claim or question. Research can produce evidence, but the two terms are not interchangeable.
Read Guide →Research usually produces evidence that changes how confidently we can support a claim, rather than absolute proof or certainty. Strong conclusions can be highly dependable while still remaining open to qualification or revision.
Read Guide →A well-designed and carefully conducted study can still reach a conclusion that later evidence does not support. Research reduces the risk of error, but empirical evidence rarely eliminates uncertainty completely.
Read Guide →A single study can make an important contribution, but it observes only a limited part of a larger phenomenon. Scientific confidence usually develops by examining how findings hold up across additional studies, contexts, methods, and evidence.
Read Guide →Research builds knowledge cumulatively rather than by simply adding one study after another. Findings are compared, replicated, challenged, extended, and synthesized until a broader pattern of evidence becomes clearer.
Read Guide →Scientific knowledge can change because conclusions are based on the best available evidence rather than protected from future scrutiny. New evidence may strengthen an existing conclusion, refine its boundaries, or occasionally overturn it.
Read Guide →When scientific knowledge changes, earlier research was not necessarily wrong. New evidence may reveal an error, but it can also refine an estimate, identify a limitation, or show that an earlier conclusion applies only under certain conditions.
Read Guide →A finding is what emerges from analyzing research data, evidence is what that finding contributes toward evaluating a claim, and a conclusion is the interpretation researchers draw from the evidence. Keeping them separate helps prevent claims from outrunning what a study actually established.
Read Guide →Research moves from observation to explanation through inference. Researchers identify patterns, propose explanations, derive implications, gather evidence that can distinguish among alternatives, and revise explanations according to how well they survive testing.
