Research Problem and Literature Review
Defining a clear research problem is the most critical step. A well-defined problem guides the entire study — from design to conclusion. The literature review establishes context and identifies gaps that the research aims to fill.
Identifying the Problem
A research problem arises from gaps in knowledge, practical difficulties, or theoretical contradictions. Sources include personal experience, academic literature, professional practice, and social issues. A good problem is specific, feasible, relevant, and researchable.
Formulating the Problem
The problem statement should be clear, concise, and focused. It often takes the form of a question or objective statement. It should specify the variables, population, and scope. Avoid problems that are too broad, too narrow, trivial, or value-laden.
Research Objectives and Questions
Research objectives state what the study aims to achieve (general and specific). Research questions operationalise the objectives into answerable queries. Both guide methodology, data collection, and analysis decisions.
Hypotheses
A hypothesis is a testable prediction about the relationship between variables. The null hypothesis (H₀) states no relationship or effect; the alternative hypothesis (H₁) states the expected relationship. Hypotheses are tested through data collection and statistical analysis.
Literature Review
A literature review surveys existing research on the topic. It identifies what is already known, theoretical frameworks, methodological approaches, and gaps. Sources include journals, books, conference proceedings, theses, and reputable online databases (Google Scholar, IEEE Xplore, ACM Digital Library).
Writing the Review
Organise the review thematically, chronologically, or methodologically. Critically analyse (don't just summarise) each source. Synthesise findings to show how they relate to your problem. End by identifying the gap your research addresses. Use proper citation throughout (APA, IEEE style).
Summary
A well-defined research problem and thorough literature review form the foundation of any study. They establish relevance, identify gaps, and shape the research design and methodology.
