Research Design & Methodology

Design the study around the question.

Research design connects what a study wants to understand with the evidence needed to answer its questions. Learn how methodology, design, sampling, data collection, and analysis work together.

Methodology should not be chosen in isolation.

The research problem and questions establish what the study needs to investigate. The methodological decisions should follow.

Research Architecture

Research design is the architecture of the study.

A dissertation is not simply a collection of chapters. It is an investigation in which the research problem, questions, methodology, evidence, analysis, and conclusions should form a coherent chain.

When those decisions are aligned, the researcher can explain not only what was done but why the approach was appropriate for answering the research questions.

A strong methodology begins with a clear research problem—not a preferred software package, test, or data collection method.

Core Research Decisions

The major pieces of a research design.

Each part answers a different question about how the study will move from a research problem to defensible findings.

01

Research Problem

The specific issue, gap, condition, or phenomenon the study is designed to investigate.

02

Research Questions

The questions define what the study needs to investigate and help shape the methodological decisions that follow.

03

Methodology

The broader research approach that provides the logic for how the study will investigate its questions.

04

Research Design

The structure used to organise the investigation and connect the research questions with evidence.

05

Sampling

The strategy used to determine who or what will provide the evidence needed for the study.

06

Data Collection

The procedures and instruments used to gather evidence relevant to the research questions.

07

Data Analysis

The analytical approach used to examine the evidence and answer the research questions.

The question is not whether each piece exists.

The question is whether the pieces make sense together.

Research Alignment

Every decision should answerthe decision before it.

Alignment means the research decisions form a coherent sequence from the problem being investigated to the evidence used to answer it.

01Research Problem

What problem requires investigation?

02Research Purpose

What is the study intended to accomplish?

03Research Questions

What exactly must the study answer?

04Methodology

What overall approach fits those questions?

05Research Design

How should the investigation be structured?

06Sampling

Who or what can provide the necessary evidence?

07Data Collection

How will that evidence be obtained?

08Data Analysis

How will the evidence be examined?

Research Approaches

Qualitative, quantitative, or mixed methods?

The appropriate approach depends on the research problem and the type of evidence required to answer the research questions.

Qualitative Research01

Understand meaning, experience, and context.

Qualitative research is used when the study requires detailed understanding of experiences, perceptions, processes, meanings, or contextual phenomena.

Quantitative Research02

Examine variables, differences, and relationships.

Quantitative research uses numerical evidence and statistical analysis to investigate questions involving measurable variables and patterns.

Mixed Methods03

Integrate qualitative and quantitative evidence.

Mixed methods research combines qualitative and quantitative approaches when the research problem benefits from more than one form of evidence.

Research Design Decisions

Five questions before choosing a method.

Research design becomes clearer when methodological choices are treated as responses to the research problem rather than isolated technical decisions.

01

What does the study need to know?

Begin with the research problem and questions rather than selecting a familiar method first.

02

What kind of evidence can answer the question?

Consider whether the study requires experiences, numerical measurements, documents, observations, or multiple forms of evidence.

03

Who or what should provide that evidence?

The population and sampling strategy should follow from the information required by the research questions.

04

How should the evidence be collected?

Interviews, surveys, observations, records, assessments, and other methods should be selected because they generate appropriate evidence.

05

How should the evidence be analysed?

The analytical approach must fit the research question, design, type of data, and claims the study intends to make.

Research Alignment in Practice

An approved analysis can still be misaligned.

TheGear has previously discussed an example involving a causal-comparative study examining performance before and after an intervention where correlation had been approved as the statistical analysis.

Study

The study involved comparing performance before and after an intervention.

Issue

Correlation had been approved even though the study involved a comparison question.

Lesson

Statistical techniques must be evaluated in the context of the research question and design.

This example illustrates research alignment. No unsupported claim is being made here about the final analysis selected or the outcome of the study.

Research Design FAQ

Common methodology questions.

01

What is the difference between research methodology and research design?

Methodology describes the broader approach and logic used to investigate the research problem, while research design describes how the study is structured to answer its research questions. The two are closely connected but are not interchangeable.

02

Should I choose my methodology before writing the research questions?

The methodology should normally follow from the research problem, purpose, and questions. Choosing a methodology first can create alignment problems if the selected approach cannot adequately answer the questions the study eventually asks.

03

How do I choose between qualitative and quantitative research?

The choice depends on what the study needs to understand and the type of evidence required to answer the research questions. Qualitative and quantitative approaches answer different kinds of questions, and neither is automatically better.

04

How does sampling relate to research design?

Sampling determines who or what will provide evidence for the study. The sampling strategy should therefore be appropriate for the methodology, research design, population, and type of evidence required.

05

When should I decide how the data will be analysed?

Analysis should be considered during research design rather than after data collection. Thinking about analysis early helps ensure that the study collects the type of evidence needed to answer the research questions.
