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.

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
Bias in research is any systematic error that distorts findings away from the true result. It can enter a study at every stage, from how participants are selected and how data is collected to how results are analyzed and reported. Unlike random error, which averages out with larger samples, bias
Research ethics is the set of principles and procedures that protect the rights, safety, and well-being of human participants in research. It governs how researchers collect data, obtain consent, maintain confidentiality, and report findings. Every study involving human participants requires ethical review, informed consent, and a data protection plan before
An operational definition specifies exactly how an abstract concept will be measured, observed, or manipulated in a research study. It translates theoretical constructs like "anxiety," "academic performance," or "job satisfaction" into concrete, observable variables with defined measurement procedures. Without operational definitions, two researchers studying
