What is Research Methodology? Definitions, Types, and Examples

Research methodology is the structured approach that guides how studies are designed, conducted, and analyzed. It explains the reasoning behind chosen methods and ensures research is reliable and meaningful.

Key takeaways:

• Research Methodology vs. Methods: Methodology focuses on the overall strategy and rationale, while methods are the specific tools (e.g., surveys, experiments).
• Types of Methodology:
  • Qualitative: Focuses on non-numerical data to understand experiences and behaviors (e.g., interviews, observations).
  • Quantitative: Uses numerical data and statistics to test hypotheses and identify patterns (e.g., surveys, experiments).
  • Mixed Methods: Combines qualitative and quantitative approaches for a more balanced understanding.
• Why It Matters: A clear methodology ensures valid results and allows others to replicate the study.

Each approach has strengths and limitations. Your choice depends on your research goals and the type of data you need.

Main Types of Research Methodology

Research methodologies are typically categorized into three main types. Choosing the right one depends on your research goals and the questions you aim to answer. This framework helps researchers align their study design with their objectives.

Qualitative Research Methodology

Qualitative research deals with non-numerical data, focusing on experiences, perceptions, and social phenomena. It seeks to understand the "how" and "why" behind human behavior and interactions. Instead of numbers, this approach emphasizes context and deeper meaning.

Common techniques include in-depth interviews, focus groups, observations, and case studies. Researchers often immerse themselves in participants' environments to gain firsthand insights into their perspectives and experiences.

One of the key benefits of qualitative research is its ability to provide context and explore complex social dynamics that numbers alone can't reveal. However, its smaller sample sizes can make it harder to generalize findings to larger populations.

For example, in 2020, the EY Seren Teams Research examined human behavior and its influence on brand and service expectations. Using qualitative methods like virtual interviews and diary studies, the team assessed behavioral changes among a UK customer base during the pandemic.

Quantitative Research Methodology

Quantitative research, on the other hand, focuses on measurable data and statistical analysis. This methodology uses tools such as surveys, experiments, and polls to test hypotheses and examine specific variables.

Earl R. Babbie describes this approach as:

"Quantitative methods emphasize objective measurements and the statistical, mathematical, or numerical analysis of data collected through polls, questionnaires, and surveys, or by manipulating pre-existing statistical data using computational techniques. Quantitative research focuses on gathering numerical data and generalizing it across groups of people or to explain a particular phenomenon."

Fields like sociology, psychology, healthcare, education, and marketing frequently use quantitative research to identify patterns, validate theories, and make predictions based on statistical evidence.

A great example is the 2019 study by the STEP Project Global Consortium and KPMG, which analyzed ways to keep family businesses profitable over time. By using statistical tools and numerical data, the study uncovered trends and patterns across various family businesses.

Quantitative research excels at delivering results that are broadly applicable to larger populations. Its structured framework provides clear and testable findings.

Mixed Methods Research Methodology

Mixed methods research blends qualitative and quantitative approaches to offer a more comprehensive understanding than either method alone. By combining these methodologies, researchers can capitalize on their strengths while minimizing their weaknesses.

As Delve explains, mixed methods allow researchers to address diverse questions by integrating the depth of qualitative insights with the broader applicability of quantitative data.

This approach is particularly useful for overcoming limitations. For instance, while qualitative research may lack generalizability, the quantitative component ensures broader applicability. On the flip side, qualitative data adds real-world context to the often controlled settings of quantitative studies.

The EY Seren Teams Research project illustrates this approach well. After conducting qualitative interviews and diary studies, the team supplemented their findings with quantitative surveys sent to the EY community every 15 days. This combination provided both detailed insights and a broader validation of their findings.

In practice, mixed methods allow researchers to use qualitative data to interpret quantitative results or to test hypotheses generated from qualitative exploration. This dual approach creates a fuller picture of the research topic.

Real Examples and Applications of Research Methodologies

Examining real-world applications helps clarify why researchers choose specific methodologies and how these approaches address challenges across various fields. Below are examples illustrating the practical use of different research methodologies.

How Qualitative Research is Used

Qualitative research shines when the goal is to deeply understand human experiences, behaviors, or motivations. For instance, in healthcare, Puts and colleagues used semi-structured interviews with older adults battling cancer to uncover the personal factors that influenced their adherence to treatment plans. This approach revealed insights that purely numerical data couldn't capture.

In education, Shernoff and colleagues used grounded theory to study student engagement in high school classrooms. By gathering data from self-reports, interviews, and observations, they identified key factors that influenced engagement from multiple perspectives.

Another example comes from Evans, who immersed himself in the daily lives of a group of young men to understand their values and motivations. Similarly, in healthcare, Osben used autoethnography to document a day in the life of an NHS nurse, offering a reflective lens on the driving forces behind nursing practices.

"Qualitative research is a type of research that explores and provides deeper insights into real-world problems." – Steven Tenny, Janelle M. Brannan, and Grace D. Brannan

These examples highlight how qualitative methods align well with studies aiming to explore nuanced or subjective aspects of human life.

How Quantitative Research is Used

Quantitative research is ideal for studies requiring measurable outcomes, statistical validation, and generalizable findings. Take the work of Anna Unné and Kristina Rosengren, who conducted a study in northeastern Sweden to improve pain management in palliative care. They measured the use of validated pain rating tools among 22 staff members, finding an increase from 47% to 100% in the final week of patients' lives. This shift from descriptive to numerical documentation enhanced both clarity and care delivery.

Hospital design research also benefits from quantitative methods. Jill Maben, Peter Griffiths, and their team evaluated the impact of single-room hospital accommodations on staff and patients. By tracking pedometer data, they discovered that staff travel distances rose significantly, with the mean steps per hour increasing from 715 to 839 after moving to the new facility.

"Quantitative research uses statistical and quantifiable results to describe an objective reality about pain measurement to improve pain management routines." – Anna Unné and Kristina Rosengren

These examples show how quantitative methods provide clear, measurable insights, making them essential for studies focused on objective outcomes.

How Mixed Methods Research is Used

Mixed methods research becomes indispensable when a problem demands both statistical evidence and human insights. By combining the strengths of qualitative and quantitative approaches, researchers can tackle complex challenges more effectively.

For example, a fintech company used a mixed-methods approach to design a mobile banking app across five phases. They started with in-depth interviews to understand user needs, followed by quantitative market analysis to identify broader trends. During concept testing, focus groups refined the app's features, and surveys validated these ideas with a larger audience. In the prototyping phase, usability testing identified issues, which were further confirmed through quantitative metrics. Post-launch, the company monitored user interactions and collected qualitative feedback to ensure the app met expectations and complied with regulations.

In another case, a Palestinian pediatric hospital conducted a mixed-methods study to uncover barriers to pediatric palliative care. Quantitative data from electronic surveys completed by 58 healthcare professionals revealed key issues, while semi-structured interviews added depth by exploring family resistance to care and gaps in professional training.

Finally, researchers in Poland used a convergent parallel mixed-methods design to evaluate educational outcomes for medical caregivers. They combined quantitative data from 840 surveys with qualitative insights from focus groups, offering both statistical relevance and personal perspectives on caregivers' educational needs.

These examples demonstrate how mixed methods research bridges the gap between measurable data and deeper human understanding, making it a powerful tool for addressing multifaceted issues.

Key Strengths by Methodology

Qualitative research shines in exploring subjective experiences and complex behaviors, often leading to the development of new theories. Its flexibility allows researchers to adjust their approach as new insights emerge.

Quantitative research is ideal for testing hypotheses and analyzing measurable outcomes. It’s particularly effective for identifying cause-and-effect relationships and understanding large-scale trends across populations.

Mixed methods research combines the benefits of both, offering a more comprehensive view. By integrating qualitative and quantitative approaches, it addresses complex research questions that require both statistical rigor and contextual depth. As Creswell and Clark note, this approach is particularly valuable for studies needing insights from both perspectives.

Understanding the Limitations

Each methodology has its own set of challenges. Qualitative research, while rich in detail, can be time-consuming and less generalizable. Quantitative research, though statistically robust, may overlook important contextual nuances. Mixed methods research, while comprehensive, demands expertise in both approaches and requires significant resources to execute effectively.

Interestingly, despite its potential, mixed-methods research is still underutilized. For example, a review found that only 1.9% of nursing studies employed this approach, highlighting an opportunity for broader adoption.

Expert Insights

Experts in the field emphasize the complementary nature of these methodologies. Annie Pettit, an Independent Insights Consultant at AP Consulting, explains:

"Quantitative research is inherently no more nor less important than qualitative research. In fact, great researchers strive to incorporate both so as to generate a deeper and more complete understanding of human behavior".

Similarly, James Redden, CEO APAC/US at 2CV, highlights the balance between the two:

"While qualitative research is crucial for understanding the issues at play and why people may behave or think a certain way, only strong quantitative research with sizeable sample sizes can provide companies with an accurate understanding of a whole market or segment".

Making the Right Choice

Your choice of methodology should reflect your research questions, goals, and available resources. Whether you need statistical validation, a deep contextual understanding, or both, aligning your approach with your objectives is essential for meaningful results.
