Documentary analysis is a qualitative research method that involves the systematic examination of documents to understand and interpret their meaning and context. It is used to uncover insights into historical, cultural, or social phenomena by analyzing the content, structure, and purpose of documents, often complementing other research methods.
Retrospective analysis involves examining past events or data to understand trends, outcomes, or behaviors, often to inform future decision-making. It is widely used in fields like healthcare, finance, and project management to evaluate the effectiveness of interventions or strategies and to identify areas for improvement.
Postgraduate research involves advanced academic study and original investigations undertaken after obtaining a bachelor's degree, often leading to a master's or doctoral degree. It emphasizes independent study, critical thinking, and contributing new knowledge or insights to a specific field of study.
