Academic ResearchGlossary

A status indicating a doctoral student has completed all program requirements except the dissertation. While not an official credential, it's commonly used in US academic contexts to describe candidates in the final research phase.

A concise summary (typically 150-350 words) of the entire dissertation or thesis. Should include purpose, methodology, key findings, and implications. Often written last.

A section thanking individuals and organizations that contributed to the research. Typically includes supervisors, funding bodies, participants, and personal supporters.

Supplementary material placed at the end of a dissertation, including questionnaires, interview guides, detailed tables, or additional data. Referenced in the main text.

The formal status achieved after passing qualifying or comprehensive exams, indicating a student has advanced to the dissertation phase. Candidacy typically comes with different registration status and expectations.

An in-depth investigation of a bounded system (individual, group, organization, event) using multiple data sources. Particularly useful for exploring complex phenomena in real-world contexts.

The process of labeling and organizing qualitative data to identify themes, patterns, and categories. Includes open, axial, and selective coding phases in grounded theory approaches.

A visual or written representation of the key concepts, variables, and relationships in a study. Often researcher-developed (unlike theoretical frameworks which draw on established theories).

A substantial written document presenting original research, typically required for doctoral degrees (PhD, EdD, DBA). In the UK/Europe, refers specifically to PhD-level work; in the US, the term is used more broadly for both Master's and doctoral work.

Doctor of Philosophy—the term used at Oxford and some other UK universities instead of PhD. The qualification is equivalent to a PhD; only the naming convention differs.

A quantitative measure of the magnitude of a phenomenon or relationship. Unlike statistical significance, effect size indicates practical importance and is independent of sample size.

A qualitative methodology involving prolonged immersion in a cultural setting to understand social behaviors, beliefs, and practices from participants' perspectives. Originated in anthropology.

An expert from outside the candidate's institution appointed to examine the dissertation. Provides independent assessment and ensures standards are met.

A systematic qualitative methodology that develops theory from data through iterative coding and constant comparison. The theory 'emerges' from the data rather than being predetermined.

Academic writing technique using cautious language to acknowledge uncertainty. Words like 'may', 'might', 'suggests', and 'appears to' show appropriate scholarly caution.

A testable prediction about the relationship between variables. In quantitative research, hypotheses are typically stated as null (H₀) and alternative (H₁) forms and tested through statistical analysis.

The process of ensuring research participants understand the study's purpose, procedures, risks, and their rights before agreeing to participate. A fundamental ethical requirement.

A committee that reviews research involving human subjects to ensure ethical standards are met. Required approval before data collection in most institutions.

A comprehensive survey and synthesis of existing research on a topic. A required chapter in both theses and dissertations, establishing the research context, identifying gaps, and justifying the study's contribution.

Substantial revisions required after a viva, involving significant rewriting or additional analysis. Typically must be completed within 6-12 months and may require re-examination.

Small revisions required after a viva, typically typographical or clarification issues. Usually must be completed within 1-3 months and reviewed by the internal examiner.

Research approach combining qualitative and quantitative methods in a single study. Designs include convergent, explanatory sequential, exploratory sequential, and embedded approaches.

Master of Philosophy—a research-based Master's degree common in the UK, often a stepping stone to PhD. Some programs allow upgrading from MPhil to PhD after demonstrating sufficient progress.

A formal examination where candidates present and defend their dissertation before a committee. The US term for what UK institutions call a viva voce.

A qualitative research approach focused on understanding the lived experiences of participants. Seeks to describe the essence of a phenomenon as experienced by those who have lived it.

Preferred Reporting Items for Systematic Reviews and Meta-Analyses—a set of guidelines and a flow diagram for transparent reporting of systematic review methodology.

Research methodology that explores phenomena through non-numerical data such as interviews, observations, and documents. Seeks to understand meanings, experiences, and perspectives in depth.

Research methodology that uses numerical data and statistical analysis to test hypotheses and establish relationships between variables. Emphasizes objectivity, generalizability, and replicability.

Statistical technique for examining relationships between variables and making predictions. Types include linear, multiple, logistic, and hierarchical regression.

An area where existing literature is insufficient, contradictory, or missing entirely. Identifying a research gap is essential for justifying original research and demonstrating the study's contribution to knowledge.

The central inquiry that guides a research study. Good research questions are specific, focused, and answerable through the proposed methodology. They drive data collection and analysis decisions.

Writing technique using transitional phrases to guide readers through the argument structure. Examples: 'This chapter examines...', 'Having established...', 'The following section...'

A measure indicating whether observed results are likely due to chance (p-value typically < 0.05). Does not indicate practical importance—effect size should also be considered.

A qualitative analysis method for identifying, analyzing, and reporting patterns (themes) within data. Flexible and accessible, it can be applied across various theoretical frameworks.

The underlying theory or set of theories that guides research design, data collection, and interpretation. It provides the lens through which the research problem is viewed and analyzed.

A research document demonstrating mastery of a subject, typically required for Master's degrees. In the UK/Europe, refers to Master's-level work; in the US, may refer to either Master's or doctoral work. The terminology varies significantly by region.

Using multiple data sources, methods, investigators, or theories to cross-verify findings and enhance credibility. A key strategy for establishing validity in qualitative and mixed methods research.

The oral defense of a dissertation, common in UK and European systems. Candidates defend their research before examiners (typically one internal, one external) in a formal examination.
