Research methodology vs method
In essence, methodology provides the overall research framework, while methods are the concrete steps taken to gather and analyse data within that framework. In other words, the difference between research methodology and method lies in the scope and function of a research study:
- Research methodology is the overall strategy and rationale guiding a research project. It is the framework that outlines the why and how of a study, including the research design, data collection and analysis techniques, sampling procedures and ethical considerations. Methodology addresses the broader logic and assumptions underlying the research and provides a roadmap for conducting the study systematically.
- Research methods, on the other hand, are the specific techniques or procedures used to collect and analyse data within the research. They are the tools applied to gather information or generate insights, fir instance, surveys, interviews, experiments or statistical tests. Researchers choose methods based on the methodology and directly employe them in the data collection and analysis phases.
For example, in a study exploring workplace motivation, the methodology might be a mixed-methods approach. This could entail combining quantitative surveys with qualitative interviews to get a comprehensive understanding. The methods could include specific tools like a Likert scale survey for the quantitative part and semi-structured interviews for the qualitative part.
Purpose of research methodology
Overall, the purpose of methodology in research is to provide a structured, transparent approach to the research process. Methodology also has other purposes:
- Guiding the research design: Methodology offers a blueprint for conducting the study and details the overall strategy, methods of data collection and analysis techniques. It aligns the study with its objectives, helping to address the research question effectively.
- Ensuring consistency and rigour: A clear methodology enables systematic and consistent data collection and analysis and contributes to the rigour and reliability of the findings. This helps ensure that the study is well-organised and that its procedures can be reproduced.
- Enhancing credibility and validity: By defining the research framework and rationale, methodology provides transparency. It explains the choice of methods and ensures that the research findings are credible, valid and grounded in established research practices.
- Facilitating replication: A well-documented methodology enables other researchers to replicate the study, which is essential for verifying findings and building on existing research. Replicability enhances the robustness of the research within the academic community.
- Addressing ethical considerations: Methodology often includes ethical guidelines to ensure that the research is conducted responsibly, especially when it involves human subjects. This may include informed consent, confidentiality and considerations of potential harm.
- Identifying limitations and scope: By outlining the methodological choices, researchers can clarify the boundaries of the study, including any limitations related to the sample, research design or data collection methods. This transparency helps interpret the results accurately.
Types of research methodologies
Research methodologies can be broadly classified into several types, each suited to different research aims, questions and data requirements:
Quantitative research
Quantitative research quantifies data, identifies patterns or establishes statistical relationships. Common methods include surveys, structured observations, experiments and statistical analysis. For example, using a survey to measure customer satisfaction or conducting an experiment to test the effect of a new teaching approach.
Qualitative research
Qualitative research explores phenomena, experiences or meanings in depth. This research typically involves interviews, focus groups, narrative analysis, content analysis and case studies. For instance, interviews may be conducted to explore employee perceptions of workplace culture.
Mixed-methods research
Mixed-methods research combines quantitative and qualitative approaches to gain comprehensive insights. It often involves sequential or concurrent use of surveys, interviews and data analysis. For example, job satisfaction could be measured through surveys, with interviews providing further insight into underlying reasons.
Descriptive research
Descriptive research systematically describes characteristics or behaviours without implying causality. Methods include surveys, observations and case studies. An example is observing classroom dynamics to describe student behaviours.
Correlational research
Correlational research Examines relationships or associations between variables. Methods often involve surveys and statistical correlational analysis. For example, a study may analyse the relationship between stress levels and productivity.
Experimental research
Experimental research Seeks to establish cause-and-effect relationships by manipulating variables. Controlled and field experiments are common methods. For instance, a clinical trial might test the impact of a new drug.
Case study research
Case study research provides an in-depth analysis of a specific instance or entity. Typical methods include interviews, document analysis and observations. For example, a company’s strategic changes might be studied as a case on adaptation.
Ethnographic research
Ethnographic research involves immersing in a community to understand its cultural and social dynamics. This research typically uses long-term participant observation, in-depth interviews and field notes. For instance, studying a rural community’s agricultural practices by living with them..
Grounded theory research
Grounded theory research develops a theory based on collected data through iterative coding and constant comparison analysis. An example would be analysing interview data to create a theory on adaptation to remote work.
Action research
Action research aims to solve practical problems through collaboration with a community, using cycles of planning, action, observation and reflection. For example, working with a school to enhance student engagement.
Phenomenological research
Phenomenological research explores individuals’ lived experiences. It typically employs in-depth interviews and thematic analysis. Studying the experiences of patients with chronic illness exemplifies this approach.
Narrative research
Narrative research analyses personal stories and experiences to understand how individuals create meaning. This research often involves narrative interviews and content analysis of stories or diaries. For instance, analysing life stories of refugees to understand resilience.
Content analysis
Content analysis interprets themes and patterns in text or media. This may involve quantitative counting of occurrences or qualitative thematic analysis. For example, examining media coverage of climate change.
Longitudinal research
Longitudinal research studies changes over time within a specific group or phenomenon. Methods typically involve repeated observations and surveys over time. An example is tracking the academic progress of students over several years.
Meta-analysis and systematic review
meta-analysis and systematic review synthesises findings from multiple studies, using statistical synthesis in meta-analyses and structured reviews in systematic reviews. For example, a meta-analysis of studies on the effectiveness of remote work..
Focus groups
Focus groups gather diverse perspectives through moderated group discussions on specific topics. An example is conducting focus groups with educators to discuss a new teaching approach.
Document analysis
Document analysis reviews and analyses existing records or documents, such as official records, policy documents and historical documents. For example, analysing government reports to study changes in healthcare policy.
Secondary data analysis
Secondary data analysis involves analysing data collected by others, often using existing databases, government records or organisational data. For instance, census data could be used to examine demographic changes in education.
How to choose research methodology?
Choosing the right research methodology depends on the research question, objectives and the nature of the data required. Here is a guide to help you make an informed decision:
#1 Define your research objectives
Identify what you aim to achieve with your study. Are you seeking to understand patterns, establish relationships, explore meanings or test a hypothesis? Your objectives will help determine whether to choose a quantitative, qualitative or mixed-methods approach.
#2 Clarify your research questions or hypothesis
Clearly articulate the primary research question(s) or hypotheses. For example, researchers often use quantitative methodologies for questions focusing on measurable relationships. On the other hand, qualitative methodologies are suitable for exploring experiences or meanings.
#3 Consider the nature of your data
Quantitative data involves numbers, measurements and statistical analysis. Qualitative data consists of text, images or observations that capture deeper insights and experiences. If your data needs are mixed, a mixed-methods approach might be best.
#4 Determine the level of control needed
Experimental methodologies (like controlled experiments) are ideal for studies where the researcher needs to control variables to determine causation.
If you are observing natural settings with minimal interference, methodologies like ethnography or case studies may be more suitable.
#5 Assess the research context and setting
Certain methodologies, like ethnography or action research, require the researcher to engage directly with the participants or context. On the other hand, other methodologies, like surveys or secondary data analysis, can be conducted without direct involvement.
#6 Evaluate the time and resources available
Some methodologies, such as longitudinal studies, require significant time. Ethnographic and qualitative studies can also be resource-intensive. For projects with limited time and resources, methods like surveys or secondary data analysis are generally more feasible.
#7 Consider the scope of the study
Broad questions aiming to identify general patterns may benefit from quantitative surveys or experiments with large samples. In contrast, narrow, specific questions that explore phenomena in depth are better suited to qualitative methods, like case studies or in-depth interviews.
#8 Take ethical considerations into account
Certain methodologies, such as those involving vulnerable populations or sensitive topics, may have stricter ethical guidelines. Ensure the methodology you choose aligns with ethical standards for confidentiality, informed consent and participant well-being.
#9 Review existing literature and past studies
Look at similar studies to see which methodologies they used and consider whether these could apply to your research. This can provide insights into common methodological choices for your topic and highlight potential limitations or strengths.
#10 Get feedback
Discussing your proposed methodology with experts, mentors or peers can provide valuable feedback and help you refine your approach.

Example research methodology section
Research design
This study adopts a mixed-methods approach, combining quantitative and qualitative data to provide a comprehensive understanding of the research question. The mixed-methods design allows for statistical analysis of trends and in-depth exploration of individual experiences. Thus, this methodology is suitable for addressing both the measurable and contextual aspects of the research.
Participants or sample
The study focuses on a sample drawn from a population of university students aged 18–25. A purposive sampling method was used to ensure participants had relevant experience with the study topic. The sample size includes 100 students. Inclusion criteria required participants to be enrolled in undergraduate programmes and willing to participate; exclusion criteria included any prior involvement in similar research studies.
Data collection methods
Data was collected through surveys and semi-structured interviews. The survey provided quantitative data on general attitudes and behaviours; the interviews offered qualitative insights into participants’ experiences and perceptions. This combination allowed for a more robust understanding of broad trends and individual narratives, directly addressing the research objectives.
Data collection procedures
Surveys were administered online through a secure platform and responses were anonymised. Participants who completed the survey were then invited for interviews, which were conducted via video call and lasted 30–45 minutes each. An interview guide was used to ensure consistency, covering key themes while allowing flexibility for participants to expand on their experiences.
Data analysis techniques
Quantitative survey data was analysed using regression analysis to identify correlations between variables. Qualitative interview data was processed through thematic analysis, with coding conducted using NVivo software to identify recurring themes and patterns. This dual approach ensured both statistical rigour and depth in thematic exploration.
Ethical considerations
Ethical approval was obtained from the university’s ethics board. Participants provided informed consent and were assured of their confidentiality and the secure handling of their data. All data was stored in encrypted files, accessible only to the research team, ensuring compliance with data protection standards.
Limitations and assumptions
Limitations include the potential for self-reporting bias in survey responses and the limited generalisability of findings due to the purposive sample. An assumption is that participants provided honest and accurate responses to both the survey and interview questions.
Justification for methodological choices
The mixed-methods design was selected to leverage the strengths of both quantitative and qualitative data, providing a balanced view of the research question. Purposive sampling ensured relevance in the sample, while the chosen data collection and analysis techniques allowed for a comprehensive insight into both statistical trends and individual perspectives.
Instrumentation or materials used
Instrumentation included an online survey platform, an interview guide for semi-structured interviews and NVivo software for qualitative data analysis. These tools were chosen to ensure reliability, consistency and depth in data analysis.
