How to Write a Research Design – Guide with Examples

Published by Alaxendra Bets at August 14th, 2021 , Revised On June 24, 2024

A research design is a structure that combines different components of research. It involves the use of different data collection and data analysis techniques logically to answer the  research questions .

It would be best to make some decisions about addressing the research questions adequately before starting the research process, which is achieved with the help of the research design.

Below are the key aspects of the decision-making process:

• Data type required for research
• Research resources
• Participants required for research
• Hypothesis based upon research question(s)
• Data analysis  methodologies
• Variables (Independent, dependent, and confounding)
• The location and timescale for conducting the data
• The time period required for research

The research design provides the strategy of investigation for your project. Furthermore, it defines the parameters and criteria to compile the data to evaluate results and conclude.

Your project’s validity depends on the data collection and  interpretation techniques.  A strong research design reflects a strong  dissertation , scientific paper, or research proposal .

Step 1: Establish Priorities for Research Design

Before conducting any research study, you must address an important question: “how to create a research design.”

The research design depends on the researcher’s priorities and choices because every research has different priorities. For a complex research study involving multiple methods, you may choose to have more than one research design.

Multimethodology or multimethod research includes using more than one data collection method or research in a research study or set of related studies.

If one research design is weak in one area, then another research design can cover that weakness. For instance, a  dissertation analyzing different situations or cases will have more than one research design.

For example:

• Experimental research involves experimental investigation and laboratory experience, but it does not accurately investigate the real world.
• Quantitative research is good for the  statistical part of the project, but it may not provide an in-depth understanding of the  topic .
• Also, correlational research will not provide experimental results because it is a technique that assesses the statistical relationship between two variables.

While scientific considerations are a fundamental aspect of the research design, It is equally important that the researcher think practically before deciding on its structure. Here are some questions that you should think of;

• Do you have enough time to gather data and complete the write-up?
• Will you be able to collect the necessary data by interviewing a specific person or visiting a specific location?
• Do you have in-depth knowledge about the  different statistical analysis and data collection techniques to address the research questions  or test the  hypothesis ?

If you think that the chosen research design cannot answer the research questions properly, you can refine your research questions to gain better insight.

Step 2: Data Type you Need for Research

Decide on the type of data you need for your research. The type of data you need to collect depends on your research questions or research hypothesis. Two types of research data can be used to answer the research questions:

Primary Data Vs. Secondary Data

Qualitative vs. quantitative data.

Step 3: Data Collection Techniques

Once you have selected the type of research to answer your research question, you need to decide where and how to collect the data.

It is time to determine your research method to address the  research problem . Research methods involve procedures, techniques, materials, and tools used for the study.

For instance, a dissertation research design includes the different resources and data collection techniques and helps establish your  dissertation’s structure .

The following table shows the characteristics of the most popularly employed research methods.

Research Methods

Step 4: Procedure of Data Analysis

Use of the  correct data and statistical analysis technique is necessary for the validity of your research. Therefore, you need to be certain about the data type that would best address the research problem. Choosing an appropriate analysis method is the final step for the research design. It can be split into two main categories;

Quantitative Data Analysis

The quantitative data analysis technique involves analyzing the numerical data with the help of different applications such as; SPSS, STATA, Excel, origin lab, etc.

This data analysis strategy tests different variables such as spectrum, frequencies, averages, and more. The research question and the hypothesis must be established to identify the variables for testing.

Qualitative Data Analysis

Qualitative data analysis of figures, themes, and words allows for flexibility and the researcher’s subjective opinions. This means that the researcher’s primary focus will be interpreting patterns, tendencies, and accounts and understanding the implications and social framework.

You should be clear about your research objectives before starting to analyze the data. For example, you should ask yourself whether you need to explain respondents’ experiences and insights or do you also need to evaluate their responses with reference to a certain social framework.

Step 5: Write your Research Proposal

The research design is an important component of a research proposal because it plans the project’s execution. You can share it with the supervisor, who would evaluate the feasibility and capacity of the results  and  conclusion .

Read our guidelines to write a research proposal  if you have already formulated your research design. The research proposal is written in the future tense because you are writing your proposal before conducting research.

The  research methodology  or research design, on the other hand, is generally written in the past tense.

How to Write a Research Design – Conclusion

A research design is the plan, structure, strategy of investigation conceived to answer the research question and test the hypothesis. The dissertation research design can be classified based on the type of data and the type of analysis.

Above mentioned five steps are the answer to how to write a research design. So, follow these steps to  formulate the perfect research design for your dissertation .

Research Design | Step-by-Step Guide with Examples

Published on 5 May 2022 by Shona McCombes . Revised on 20 March 2023.

A research design is a strategy for answering your research question  using empirical data. Creating a research design means making decisions about:

• Your overall aims and approach
• The type of research design you’ll use
• Your sampling methods or criteria for selecting subjects
• Your data collection methods
• The procedures you’ll follow to collect data
• Your data analysis methods

A well-planned research design helps ensure that your methods match your research aims and that you use the right kind of analysis for your data.

Table of contents

Step 1: consider your aims and approach, step 2: choose a type of research design, step 3: identify your population and sampling method, step 4: choose your data collection methods, step 5: plan your data collection procedures, step 6: decide on your data analysis strategies, frequently asked questions.

• Introduction

Before you can start designing your research, you should already have a clear idea of the research question you want to investigate.

There are many different ways you could go about answering this question. Your research design choices should be driven by your aims and priorities – start by thinking carefully about what you want to achieve.

The first choice you need to make is whether you’ll take a qualitative or quantitative approach.

Qualitative research designs tend to be more flexible and inductive , allowing you to adjust your approach based on what you find throughout the research process.

Quantitative research designs tend to be more fixed and deductive , with variables and hypotheses clearly defined in advance of data collection.

It’s also possible to use a mixed methods design that integrates aspects of both approaches. By combining qualitative and quantitative insights, you can gain a more complete picture of the problem you’re studying and strengthen the credibility of your conclusions.

Practical and ethical considerations when designing research

As well as scientific considerations, you need to think practically when designing your research. If your research involves people or animals, you also need to consider research ethics .

• How much time do you have to collect data and write up the research?
• Will you be able to gain access to the data you need (e.g., by travelling to a specific location or contacting specific people)?
• Do you have the necessary research skills (e.g., statistical analysis or interview techniques)?
• Will you need ethical approval ?

At each stage of the research design process, make sure that your choices are practically feasible.

Prevent plagiarism, run a free check.

Within both qualitative and quantitative approaches, there are several types of research design to choose from. Each type provides a framework for the overall shape of your research.

Types of quantitative research designs

Quantitative designs can be split into four main types. Experimental and   quasi-experimental designs allow you to test cause-and-effect relationships, while descriptive and correlational designs allow you to measure variables and describe relationships between them.

With descriptive and correlational designs, you can get a clear picture of characteristics, trends, and relationships as they exist in the real world. However, you can’t draw conclusions about cause and effect (because correlation doesn’t imply causation ).

Experiments are the strongest way to test cause-and-effect relationships without the risk of other variables influencing the results. However, their controlled conditions may not always reflect how things work in the real world. They’re often also more difficult and expensive to implement.

Types of qualitative research designs

Qualitative designs are less strictly defined. This approach is about gaining a rich, detailed understanding of a specific context or phenomenon, and you can often be more creative and flexible in designing your research.

The table below shows some common types of qualitative design. They often have similar approaches in terms of data collection, but focus on different aspects when analysing the data.

Your research design should clearly define who or what your research will focus on, and how you’ll go about choosing your participants or subjects.

In research, a population is the entire group that you want to draw conclusions about, while a sample is the smaller group of individuals you’ll actually collect data from.

Defining the population

A population can be made up of anything you want to study – plants, animals, organisations, texts, countries, etc. In the social sciences, it most often refers to a group of people.

For example, will you focus on people from a specific demographic, region, or background? Are you interested in people with a certain job or medical condition, or users of a particular product?

The more precisely you define your population, the easier it will be to gather a representative sample.

Sampling methods

Even with a narrowly defined population, it’s rarely possible to collect data from every individual. Instead, you’ll collect data from a sample.

To select a sample, there are two main approaches: probability sampling and non-probability sampling . The sampling method you use affects how confidently you can generalise your results to the population as a whole.

Probability sampling is the most statistically valid option, but it’s often difficult to achieve unless you’re dealing with a very small and accessible population.

For practical reasons, many studies use non-probability sampling, but it’s important to be aware of the limitations and carefully consider potential biases. You should always make an effort to gather a sample that’s as representative as possible of the population.

Case selection in qualitative research

In some types of qualitative designs, sampling may not be relevant.

For example, in an ethnography or a case study, your aim is to deeply understand a specific context, not to generalise to a population. Instead of sampling, you may simply aim to collect as much data as possible about the context you are studying.

In these types of design, you still have to carefully consider your choice of case or community. You should have a clear rationale for why this particular case is suitable for answering your research question.

For example, you might choose a case study that reveals an unusual or neglected aspect of your research problem, or you might choose several very similar or very different cases in order to compare them.

Data collection methods are ways of directly measuring variables and gathering information. They allow you to gain first-hand knowledge and original insights into your research problem.

You can choose just one data collection method, or use several methods in the same study.

Survey methods

Surveys allow you to collect data about opinions, behaviours, experiences, and characteristics by asking people directly. There are two main survey methods to choose from: questionnaires and interviews.

Observation methods

Observations allow you to collect data unobtrusively, observing characteristics, behaviours, or social interactions without relying on self-reporting.

Observations may be conducted in real time, taking notes as you observe, or you might make audiovisual recordings for later analysis. They can be qualitative or quantitative.

Other methods of data collection

There are many other ways you might collect data depending on your field and topic.

If you’re not sure which methods will work best for your research design, try reading some papers in your field to see what data collection methods they used.

Secondary data

If you don’t have the time or resources to collect data from the population you’re interested in, you can also choose to use secondary data that other researchers already collected – for example, datasets from government surveys or previous studies on your topic.

With this raw data, you can do your own analysis to answer new research questions that weren’t addressed by the original study.

Using secondary data can expand the scope of your research, as you may be able to access much larger and more varied samples than you could collect yourself.

However, it also means you don’t have any control over which variables to measure or how to measure them, so the conclusions you can draw may be limited.

As well as deciding on your methods, you need to plan exactly how you’ll use these methods to collect data that’s consistent, accurate, and unbiased.

Planning systematic procedures is especially important in quantitative research, where you need to precisely define your variables and ensure your measurements are reliable and valid.

Operationalisation

Some variables, like height or age, are easily measured. But often you’ll be dealing with more abstract concepts, like satisfaction, anxiety, or competence. Operationalisation means turning these fuzzy ideas into measurable indicators.

If you’re using observations , which events or actions will you count?

If you’re using surveys , which questions will you ask and what range of responses will be offered?

You may also choose to use or adapt existing materials designed to measure the concept you’re interested in – for example, questionnaires or inventories whose reliability and validity has already been established.

Reliability and validity

Reliability means your results can be consistently reproduced , while validity means that you’re actually measuring the concept you’re interested in.

For valid and reliable results, your measurement materials should be thoroughly researched and carefully designed. Plan your procedures to make sure you carry out the same steps in the same way for each participant.

If you’re developing a new questionnaire or other instrument to measure a specific concept, running a pilot study allows you to check its validity and reliability in advance.

Sampling procedures

As well as choosing an appropriate sampling method, you need a concrete plan for how you’ll actually contact and recruit your selected sample.

That means making decisions about things like:

• How many participants do you need for an adequate sample size?
• What inclusion and exclusion criteria will you use to identify eligible participants?
• How will you contact your sample – by mail, online, by phone, or in person?

If you’re using a probability sampling method, it’s important that everyone who is randomly selected actually participates in the study. How will you ensure a high response rate?

If you’re using a non-probability method, how will you avoid bias and ensure a representative sample?

Data management

It’s also important to create a data management plan for organising and storing your data.

Will you need to transcribe interviews or perform data entry for observations? You should anonymise and safeguard any sensitive data, and make sure it’s backed up regularly.

Keeping your data well organised will save time when it comes to analysing them. It can also help other researchers validate and add to your findings.

On their own, raw data can’t answer your research question. The last step of designing your research is planning how you’ll analyse the data.

Quantitative data analysis

In quantitative research, you’ll most likely use some form of statistical analysis . With statistics, you can summarise your sample data, make estimates, and test hypotheses.

Using descriptive statistics , you can summarise your sample data in terms of:

• The distribution of the data (e.g., the frequency of each score on a test)
• The central tendency of the data (e.g., the mean to describe the average score)
• The variability of the data (e.g., the standard deviation to describe how spread out the scores are)

The specific calculations you can do depend on the level of measurement of your variables.

Using inferential statistics , you can:

• Make estimates about the population based on your sample data.
• Test hypotheses about a relationship between variables.

Regression and correlation tests look for associations between two or more variables, while comparison tests (such as t tests and ANOVAs ) look for differences in the outcomes of different groups.

Your choice of statistical test depends on various aspects of your research design, including the types of variables you’re dealing with and the distribution of your data.

Qualitative data analysis

In qualitative research, your data will usually be very dense with information and ideas. Instead of summing it up in numbers, you’ll need to comb through the data in detail, interpret its meanings, identify patterns, and extract the parts that are most relevant to your research question.

Two of the most common approaches to doing this are thematic analysis and discourse analysis .

There are many other ways of analysing qualitative data depending on the aims of your research. To get a sense of potential approaches, try reading some qualitative research papers in your field.

A sample is a subset of individuals from a larger population. Sampling means selecting the group that you will actually collect data from in your research.

For example, if you are researching the opinions of students in your university, you could survey a sample of 100 students.

Statistical sampling allows you to test a hypothesis about the characteristics of a population. There are various sampling methods you can use to ensure that your sample is representative of the population as a whole.

Operationalisation means turning abstract conceptual ideas into measurable observations.

For example, the concept of social anxiety isn’t directly observable, but it can be operationally defined in terms of self-rating scores, behavioural avoidance of crowded places, or physical anxiety symptoms in social situations.

Before collecting data , it’s important to consider how you will operationalise the variables that you want to measure.

The research methods you use depend on the type of data you need to answer your research question .

• If you want to measure something or test a hypothesis , use quantitative methods . If you want to explore ideas, thoughts, and meanings, use qualitative methods .
• If you want to analyse a large amount of readily available data, use secondary data. If you want data specific to your purposes with control over how they are generated, collect primary data.
• If you want to establish cause-and-effect relationships between variables , use experimental methods. If you want to understand the characteristics of a research subject, use descriptive methods.

Research Design – Types, Methods and Examples

Table of Contents

Research design is the framework or blueprint that guides the collection, measurement, and analysis of data in a study. It provides a structured approach to answering research questions, ensuring that the study’s goals are met in an organized, reliable, and valid manner. Research design is crucial as it directly impacts the study’s quality, credibility, and findings.

Research Design

Research design is a systematic plan outlining how a study is conducted, including methods of data collection, procedures, and tools for analysis. It aligns the research question with the appropriate methods, ensuring that the study remains focused, feasible, and ethically sound.

Purpose of Research Design :

• Provides a structured approach for data collection and analysis.
• Ensures consistency in the research process.
• Enhances the reliability and validity of findings.
• Minimizes bias by defining clear procedures and controls.

Types of Research Design

Research designs are typically classified into three main types: qualitative , quantitative , and mixed methods . Each type serves different purposes and is selected based on the nature of the research question, objectives, and resources.

1. Qualitative Research Design

• Definition : Qualitative research focuses on exploring complex phenomena, understanding individual experiences, and generating insights into social or human behavior. It often involves non-numerical data, such as interviews, observations, and textual analysis.
• Case Study : In-depth analysis of a specific individual, group, or event.
• Ethnography : Study of cultural groups and practices within their natural setting.
• Grounded Theory : Development of a theory based on observed data.
• Phenomenology : Exploration of lived experiences and perceptions.
• Example : A case study on how remote work impacts employee well-being by conducting interviews with employees from various industries to gather personal insights and themes.

2. Quantitative Research Design

• Definition : Quantitative research is focused on quantifying variables and using statistical analysis to test hypotheses. It often involves large samples, standardized data collection tools, and numerical data.
• Descriptive : Provides a summary of characteristics or behaviors within a population (e.g., surveys, cross-sectional studies).
• Correlational : Examines relationships between two or more variables without manipulating them.
• Experimental : Involves manipulation of variables to establish cause-and-effect relationships.
• Quasi-Experimental : Similar to experimental design but lacks random assignment.
• Example : An experimental study investigating the effect of a new teaching method on student test scores, with one group using the new method and a control group using traditional methods.

3. Mixed-Methods Research Design

• Definition : Mixed-methods design combines both qualitative and quantitative approaches in a single study, providing a more comprehensive analysis of the research question.
• Explanatory Sequential Design : Quantitative data is collected and analyzed first, followed by qualitative data to explain or expand on the quantitative findings.
• Exploratory Sequential Design : Qualitative data is collected first to explore a phenomenon, followed by quantitative data to confirm or generalize findings.
• Convergent Design : Both qualitative and quantitative data are collected simultaneously and compared to produce integrated insights.
• Example : A study on customer satisfaction, first surveying customers to get quantitative data and then conducting follow-up interviews to explore specific customer feedback in detail.

Methods in Research Design

Various methods are used within research designs to collect and analyze data. Each method is selected based on the research question, data type, and study objectives.

1. Survey and Questionnaire

• Definition : Surveys and questionnaires are tools for collecting standardized data from large samples. They are often used in descriptive and correlational studies.
• Develop questions related to the research objectives.
• Distribute to participants via online platforms, paper forms, or face-to-face interviews.
• Analyze results using statistical software for quantitative insights.
• Example : A survey assessing consumer satisfaction with a new product by collecting data on factors such as ease of use, design, and performance.

2. Interview

• Definition : Interviews are qualitative methods that gather in-depth information through direct questioning. They can be structured, semi-structured, or unstructured.
• Design interview questions that align with the research goals.
• Conduct interviews in person, via phone, or virtually, recording responses for analysis.
• Use thematic or content analysis to interpret findings.
• Example : Conducting semi-structured interviews with educators to explore their experiences with online teaching during the COVID-19 pandemic.

3. Observation

• Definition : Observation involves recording behaviors, actions, or events as they occur naturally. It is often used in ethnographic and case study designs.
• Choose between participant (researcher actively engages) or non-participant observation.
• Develop an observation checklist or guide for consistency.
• Record findings, often through field notes or video, and analyze for patterns.
• Example : Observing interactions in a classroom setting to study student engagement with different teaching methods.

4. Experiment

• Definition : Experiments involve manipulating variables to examine cause-and-effect relationships. They are commonly used in scientific and clinical research.
• Randomly assign participants to control and experimental groups.
• Manipulate the independent variable and measure changes in the dependent variable.
• Use statistical analysis to interpret results.
• Example : A laboratory experiment testing the effectiveness of a new drug on blood pressure by comparing outcomes in treated and untreated groups.

5. Case Study

• Definition : A case study is an in-depth investigation of an individual, group, organization, or event to explore underlying principles and patterns.
• Select a case that represents the phenomenon of interest.
• Use various data sources, including interviews, documents, and observations.
• Analyze for unique insights and apply findings to broader contexts.
• Example : A case study on the strategies a small business used to survive during an economic recession.

Examples of Research Design Applications

• Design : Quantitative, using a survey.
• Goal : To understand consumer preferences for eco-friendly packaging.
• Method : Survey distributed to a random sample of consumers asking about purchasing behaviors and attitudes toward sustainability.
• Design : Experimental, quantitative.
• Goal : To study the effect of sleep deprivation on cognitive performance.
• Method : Participants are randomly assigned to sleep-deprived and control groups, with cognitive performance measured using standardized tests.
• Design : Convergent mixed-methods.
• Goal : To evaluate the effectiveness of a new curriculum on student learning.
• Method : Collect quantitative data from student test scores and qualitative data from teacher interviews to provide a comprehensive evaluation.
• Design : Qualitative, ethnography.
• Goal : To study cultural practices in rural communities.
• Method : The researcher spends an extended period within the community, observing daily activities and conducting informal interviews.

Tips for Choosing the Right Research Design

• Align with Research Question : Choose a design that directly addresses the research question and allows for valid answers.
• Consider Data Type : Decide whether the research requires quantitative (numerical) or qualitative (textual or observational) data.
• Assess Feasibility : Take into account time, resources, and access to participants when selecting a design.
• Ensure Ethical Compliance : Make sure the design is ethically sound, with informed consent and confidentiality for participants.
• Anticipate Limitations : Be aware of potential limitations in each design type and how they might affect your findings.

Challenges in Research Design

• Sample Selection Bias : Choosing a non-representative sample can lead to biased results and impact the study’s validity.
• Data Collection Constraints : Limitations in resources or participant access may affect data quality.
• Ethical Concerns : Research involving vulnerable populations or sensitive topics requires careful ethical consideration.
• External Validity : Some designs, like case studies, may have limited generalizability beyond the studied context.

Research design is a critical component of the research process, as it determines how a study is structured, conducted, and analyzed. By choosing the appropriate design—whether qualitative, quantitative, or mixed methods—researchers ensure that they answer their questions effectively, producing credible, reliable, and valid results. A solid research design aligns with the study’s objectives, considers resources and ethical issues, and anticipates limitations to provide meaningful contributions to knowledge.
