Understanding Research Methods
Research methods are systematic procedures used to collect, analyse and interpret evidence to answer a research question. The choice of method depends on the purpose of the study, the nature of the question, the available evidence and the kind of conclusion the researcher seeks to draw.
Descriptive research
Describes the characteristics, status, behaviour or distribution of a phenomenon as it exists.
Historical research
Investigates past events and developments using historical evidence and critical interpretation.
Qualitative research
Explores meanings, experiences, perceptions and social contexts, often through non-numerical data.
Quantitative research
Measures variables numerically and uses statistical analysis to examine patterns, differences or relationships.
Learning outcomes
- Distinguish descriptive and historical research by their principal purpose.
- Identify primary and secondary historical sources.
- Recognise phenomenology, ethnography and grounded theory.
- Understand measurement, hypothesis testing, surveys and correlation.
- Distinguish research purpose from data type and research design.
- Apply concepts to UGC NET-style questions.
Four approaches at a glance
| Approach | Main question | Typical evidence |
|---|---|---|
| Descriptive | What exists? What are its characteristics? | Surveys, observations, records and descriptions. |
| Historical | What happened in the past, and how do we know? | Archives, documents, letters, inscriptions and contemporary accounts. |
| Qualitative | How do people experience or interpret something? | Interviews, narratives, field notes, observations and documents. |
| Quantitative | How many? How much? What measurable relationship? | Scores, counts, measurements and structured questionnaires. |
Descriptive Research
Descriptive research seeks to describe the characteristics, status, behaviour, attitudes or distribution of a group or phenomenon. It generally records existing conditions rather than deliberately manipulating variables to test a causal effect.
Typical questions include: What are the characteristics of this group? How common is a behaviour? What are the attitudes or preferences of a population?
Characteristics
- Fact-finding: gathers information about a population, group, event or situation.
- Non-manipulative in many designs: records existing conditions rather than deliberately changing the independent variable.
- Systematic: may use surveys, questionnaires, interviews, observation or existing records.
- Organised interpretation: classifies information and describes patterns or distributions.
- Flexible time frame: can be cross-sectional or longitudinal.
Examples
Learning preferences
A researcher surveys 500 university students to identify preferred learning platforms without changing their learning conditions.
School performance
A researcher describes examination results across schools in a district to identify performance patterns.
Health behaviour
A study records the proportion of adults who engage in regular physical activity.
Classroom observation
A researcher documents the frequency of classroom interactions without introducing an intervention.
Cross-sectional versus longitudinal
| Cross-sectional | Longitudinal |
|---|---|
| Examines a population or phenomenon at one point or within a short period. | Follows the same people, groups or variables over an extended period. |
| Provides a snapshot. | Helps investigate change and development. |
| Example: survey students’ study habits this month. | Example: track the same students’ study habits over three years. |
Advantages and limitations
Advantages
- Describes real-world situations.
- Identifies patterns and trends.
- Can inform planning and policy.
Limitations
- Does not automatically establish causation.
- May be affected by sampling or response bias.
- A snapshot may miss change over time.
Historical Research
Historical research investigates past events, developments, institutions, ideas or experiences. It uses available evidence to reconstruct and interpret what happened, how it developed and why particular interpretations may be justified.
The researcher asks what happened, what evidence supports an account, and how the evidence should be evaluated in context.
Primary and secondary sources
Primary sources
Evidence originating from the period or people being studied.
- Original letters and diaries
- Official records
- Inscriptions and archival documents
- Contemporary newspapers
- Photographs and participant testimony
Secondary sources
Later interpretations or analyses of historical evidence.
- History textbooks
- Scholarly historical analyses
- Review articles
- Later biographies based on documentary evidence
Major steps in historical research
Define the historical issue or question.
Locate archival records, letters, reports, inscriptions and relevant publications.
Examine authenticity, credibility, authorship, context and potential bias.
Compare accounts and investigate contradictions, gaps and historical context.
Construct an evidence-based account and acknowledge limitations.
Historical versus descriptive research
| Descriptive research | Historical research |
|---|---|
| Describes characteristics or status of a phenomenon. | Investigates past events and developments. |
| May use fresh surveys and observations. | Frequently uses historical records and documents. |
| Example: current university enrolment. | Example: historical development of universities. |
Qualitative Research
Qualitative research seeks to understand meanings, experiences, perceptions, behaviour and social contexts. It generally works with non-numerical information such as interviews, observations, narratives, field notes and documents.
Typical questions: How do people experience something? Why does it matter to them? How do they interpret it?
Characteristics
- Depth: explores experiences and meanings in detail.
- Non-numerical evidence: uses words, narratives, observations, field notes and documents.
- Flexible design: questions may evolve as understanding develops.
- Inductive reasoning: may develop broader patterns or concepts from specific observations.
- Contextual inquiry: examines people within social, cultural or institutional settings.
- Interpretive analysis: identifies themes, meanings and relationships in data.
Major qualitative approaches
| Approach | Main emphasis | Illustration |
|---|---|---|
| Ethnography | Culture, shared practices and group life. | Studying routines and norms within a school community. |
| Phenomenology | Lived experience and how people make sense of it. | Exploring students’ experiences of examination anxiety. |
| Grounded theory | Developing theory through systematic data collection and analysis. | Developing an explanation of how novice teachers adapt to a new school. |
| Case study | Intensive investigation of a bounded case. | Examining curriculum implementation in one school. |
| Narrative research | Stories and the way people construct accounts of experience. | Studying teachers’ career narratives. |
| Focus groups | Guided group discussion and interaction. | Exploring student perceptions of online examinations. |
| In-depth interviews | Detailed individual accounts and interpretations. | Interviewing first-generation university students. |
Advantages and limitations
Advantages
- Explores complex experiences in depth.
- May reveal meanings missed by fixed-response surveys.
- Can generate concepts and theories.
Limitations
- Analysis can be time-consuming.
- Interpretation requires reflexivity.
- Findings may be context-dependent.
Quantitative Research
Quantitative research collects and analyses numerical data to measure variables, identify patterns, test hypotheses or examine relationships. Statistical techniques are often used to summarise results and assess evidence.
Typical questions: How many? How much? How often? To what extent? Is there a measurable relationship?
Characteristics
- Numerical measurement: variables are represented using numbers.
- Structured design: instruments and procedures are often planned in advance.
- Hypothesis testing: many studies test predictions or hypotheses.
- Statistical analysis: may use percentages, averages, correlation, regression or inferential statistics.
- Deductive reasoning: often tests predictions derived from a theory or prior evidence.
- Sampling: suitable sampling designs can support generalisation.
- Measurement quality: reliability and validity of instruments affect conclusions.
Common methods and designs
| Method/design | Purpose | Example |
|---|---|---|
| Survey | Measure responses or characteristics. | Survey 1,000 students about study hours. |
| Correlational | Examine relationships between variables. | Association between study time and marks. |
| Experimental | Test an intervention under controlled conditions. | Compare outcomes under two teaching methods with an appropriate design. |
| Descriptive statistical study | Summarise numerical characteristics. | Calculate average attendance. |
Hypothesis-testing sequence
Example: students using a revision programme will obtain higher average scores.
Record examination scores using appropriate procedures.
Compare averages and apply a suitable statistical test.
Assess whether evidence supports the hypothesis, considering uncertainty and study design.
Advantages and limitations
Advantages
- Measures patterns systematically.
- Enables statistical comparison.
- Can test hypotheses.
- May support population estimates.
Limitations
- Fixed responses may miss complex experiences.
- Poor measurement weakens conclusions.
- Association alone does not prove causation.

One topic, two approaches
Qualitative question
How do students experience examination anxiety?
Method: in-depth interviews and thematic analysis.
Quantitative question
What proportion of students report high anxiety?
Method: a standardised scale and statistical analysis.
Mixed-methods research
Mixed-methods research deliberately combines qualitative and quantitative approaches within one study, with the aim of integrating the two forms of evidence to address the research problem.
A researcher surveys 500 students about examination anxiety and interviews 20 students to understand the reasons behind the survey results. The researcher then integrates the survey patterns and interview themes.
