Research
Understanding the distinction between primary and secondary sources is fundamental to conducting rigorous research. A primary source is original material created at the time of the event or phenomenon being studied, such as a laboratory experiment, survey data, historical document, or interview. A secondary source is an interpretation, analysis, or
Research
The discussion section of a research paper is where you explain what your results mean, how they relate to existing evidence, what limitations affect their interpretation, and what implications they have for theory, practice, or future research. Unlike the results section, which reports the data, the discussion interprets the data.
Research
The introduction of a research paper establishes the context for the study, identifies the research gap, and presents the research question or objectives that the study will address. It is the first substantive section the reader encounters after the abstract, and its purpose is to convince the reader that the
Research
A research rationale is the section of a proposal, thesis, or manuscript that explains why the study is necessary and what contribution it will make to existing knowledge. It answers the question every reviewer and reader will ask: why does this study matter? The rationale connects the identified research gap
Research
Publication bias occurs when the results of a study influence whether it is published, creating a systematic distortion in the available evidence. Studies with statistically significant, positive, or novel findings are more likely to be published than studies with null, negative, or inconclusive results. When a systematic review or meta-analysis
Research
Effect size is a quantitative measure of the magnitude of a phenomenon, relationship, or difference observed in a study. While statistical significance tells you whether an effect exists (whether the null hypothesis can be rejected), effect size tells you how large that effect is and whether it matters in practice.

A scoping review and a systematic review are both forms of evidence synthesis that follow structured, transparent methodologies, but they serve fundamentally different purposes. A scoping review maps the breadth and nature of available evidence on a broad topic, while a systematic review synthesizes and appraises evidence to answer a
Research
A scoping review is a type of evidence synthesis that maps the breadth and nature of research activity on a broad topic, rather than answering a narrow clinical question like a systematic review does. Researchers use scoping reviews to identify knowledge gaps, clarify key concepts, examine how research is conducted
Research
PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) is an evidence-based reporting guideline that helps researchers transparently document every phase of a systematic review. The PRISMA 2020 statement includes a 27-item checklist organized into seven sections and a four-phase flow diagram that tracks how records move from identification through
Research
A literature review is a critical survey and synthesis of existing scholarly sources on a specific topic. Rather than simply summarizing individual studies, it evaluates, compares, and connects findings to identify patterns, debates, and gaps in the current knowledge. A literature review appears in theses, dissertations, journal articles, and research
Research
A theoretical framework is the foundation of a research study that uses established theories to explain, predict, and contextualize the research problem. It connects your study to existing scholarly knowledge by identifying the key concepts, defining relationships between variables, and providing the lens through which you interpret your findings. Think
Research
A conceptual framework is a visual or written representation of the key concepts, variables, and relationships that guide a research study. It maps how the researcher understands the problem, which factors are relevant, and how those factors connect to each other and to the research question. Every empirical study needs
