This document defines key concepts in research methodology. It explains that research involves a systematic process of generating objective information to aid decisions. There are two types of research: basic research expands knowledge while applied research addresses specific problems. A theory is a set of principles used to explain relationships between variables, while a hypothesis is a testable proposition. The stages of research include introduction, literature review, methodology, findings and analysis, and conclusion chapters. A problem statement clearly defines the research problem and who is affected.
