How to Justify Your Methods in a Thesis or Dissertation

4-minute read

1st May 2023

Writing a thesis or dissertation is hard work. You’ve devoted countless hours to your research, and you want your results to be taken seriously. But how does your professor or evaluating committee know that they can trust your results? You convince them by justifying your research methods.

What Does Justifying Your Methods Mean?

In simple terms, your methods are the tools you use to obtain your data, and the justification (which is also called the methodology ) is the analysis of those tools. In your justification, your goal is to demonstrate that your research is both rigorously conducted and replicable so your audience recognizes that your results are legitimate.

The formatting and structure of your justification will depend on your field of study and your institution’s requirements, but below, we’ve provided questions to ask yourself as you outline your justification.

Why Did You Choose Your Method of Gathering Data?

Does your study rely on quantitative data, qualitative data, or both? Certain types of data work better for certain studies. How did you choose to gather that data? Evaluate your approach to collecting data in light of your research question. Did you consider any alternative approaches? If so, why did you decide not to use them? Highlight the pros and cons of various possible methods if necessary. Research results aren’t valid unless the data are valid, so you have to convince your reader that they are.

How Did You Evaluate Your Data?

Collecting your data was only the first part of your study. Once you had them, how did you use them? Do your results involve cross-referencing? If so, how was this accomplished? Which statistical analyses did you run, and why did you choose them? Are they common in your field? How did you make sure your data were statistically significant ? Is your effect size small, medium, or large? Numbers don’t always lend themselves to an obvious outcome. Here, you want to provide a clear link between the Methods and Results sections of your paper.

Did You Use Any Unconventional Approaches in Your Study?

Most fields have standard approaches to the research they use, but these approaches don’t work for every project. Did you use methods that other fields normally use, or did you need to come up with a different way of obtaining your data? Your reader will look at unconventional approaches with a more critical eye. Acknowledge the limitations of your method, but explain why the strengths of the method outweigh those limitations.

What Relevant Sources Can You Cite?

You can strengthen your justification by referencing existing research in your field. Citing these references can demonstrate that you’ve followed established practices for your type of research. Or you can discuss how you decided on your approach by evaluating other studies. Highlight the use of established techniques, tools, and measurements in your study. If you used an unconventional approach, justify it by providing evidence of a gap in the existing literature.

Two Final Tips:

● When you’re writing your justification, write for your audience. Your purpose here is to provide more than a technical list of details and procedures. This section should focus more on the why and less on the how .

● Consider your methodology as you’re conducting your research. Take thorough notes as you work to make sure you capture all the necessary details correctly. Eliminating any possible confusion or ambiguity will go a long way toward helping your justification.

In Conclusion:

Your goal in writing your justification is to explain not only the decisions you made but also the reasoning behind those decisions. It should be overwhelmingly clear to your audience that your study used the best possible methods to answer your research question. Properly justifying your methods will let your audience know that your research was effective and its results are valid.

How to Write a Compelling Justification of Your Research

When it comes to conducting research, a well-crafted justification is crucial. It not only helps you convince others of the importance and relevance of your work but also serves as a roadmap for your own research journey. In this blog post, we will focus on the art of writing compelling justifications, highlighting common pitfalls that juniors tend to fall into and providing an example of how to write a justification properly.

The Importance of a Strong Justification

Before we delve into the dos and don’ts of writing a justification, let’s first understand why it is so important. A strong justification sets the stage for your research by clearly outlining its purpose, significance, and potential impact. It helps you answer the question, “Why is this research worth pursuing?” and provides a solid foundation for the rest of your work.

Pitfalls to Avoid

As junior researchers, it’s common to make certain mistakes when writing a justification. Here are a few pitfalls to watch out for:

Lack of Clarity: One of the biggest mistakes is failing to clearly articulate the problem or research question. Make sure your justification clearly explains what you intend to investigate and why it matters.
Insufficient Background: Providing a strong background is essential to demonstrate your knowledge of existing literature and the context of your research. Avoid the trap of assuming that your readers are already familiar with the topic.
Weak Significance: Your justification should emphasize the significance of your research. Highlight the potential benefits, practical applications, or theoretical contributions that your work can offer.
Lack of Originality: It’s important to showcase the novelty of your research. Avoid simply replicating previous studies or rehashing existing ideas. Instead, highlight the unique aspects of your approach or the gaps in current knowledge that your research aims to fill.

Writing a Proper Justification

Now that we’ve covered the common pitfalls, let’s take a look at an example of how to write a proper justification. Imagine you are conducting research on the low proportion of uncontrolled hypertension in a specific population. Here’s how you could structure your justification:

Introduction: Begin by providing an overview of the problem and its significance. Explain why uncontrolled hypertension is a critical health issue and the potential consequences it can have on individuals and society.

Background: Offer a comprehensive review of the existing literature on hypertension, highlighting the current knowledge gaps and limitations. Discuss the prevalence of uncontrolled hypertension and the factors contributing to its low proportion in the specific population you are studying.

Objectives: Clearly state the objectives of your research. For example, your objectives could be to identify the barriers to hypertension control, evaluate the effectiveness of current interventions, and propose strategies to improve the management of uncontrolled hypertension.

Methodology: Briefly describe the research methods you plan to employ, such as surveys, interviews, or data analysis. Explain how these methods will help you address the research objectives and fill the existing knowledge gaps.

Expected Outcomes: Highlight the potential outcomes and impact of your research. Discuss how your findings could contribute to improving hypertension control rates, enhancing healthcare policies, or guiding future research in this field.

Conclusion: Summarize the main points of your justification and reiterate the significance of your research. Emphasize why your work is unique and necessary to advance knowledge and address the problem of low proportion of uncontrolled hypertension.

Remember, a compelling justification should be concise, persuasive, and grounded in evidence. It should convince your audience that your research is not only relevant but also necessary. By avoiding common pitfalls and following a structured approach, you can craft a justification that captivates readers and sets the stage for a successful research endeavor.

How to Write the Rationale of the Study in Research (Examples)

What is the Rationale of the Study?

The rationale of the study is the justification for taking on a given study. It explains the reason the study was conducted or should be conducted. This means the study rationale should explain to the reader or examiner why the study is/was necessary. It is also sometimes called the “purpose” or “justification” of a study. While this is not difficult to grasp in itself, you might wonder how the rationale of the study is different from your research question or from the statement of the problem of your study, and how it fits into the rest of your thesis or research paper.

The rationale of the study links the background of the study to your specific research question and justifies the need for the latter on the basis of the former. In brief, you first provide and discuss existing data on the topic, and then you tell the reader, based on the background evidence you just presented, where you identified gaps or issues and why you think it is important to address those. The problem statement, lastly, is the formulation of the specific research question you choose to investigate, following logically from your rationale, and the approach you are planning to use to do that.

The basis for writing a research rationale is preliminary data or a clear description of an observation. If you are doing basic/theoretical research, then a literature review will help you identify gaps in current knowledge. In applied/practical research, you base your rationale on an existing issue with a certain process (e.g., vaccine proof registration) or practice (e.g., patient treatment) that is well documented and needs to be addressed. By presenting the reader with earlier evidence or observations, you can (and have to) convince them that you are not just repeating what other people have already done or said and that your ideas are not coming out of thin air.

Once you have explained where you are coming from, you should justify the need for doing additional research–this is essentially the rationale of your study. Finally, when you have convinced the reader of the purpose of your work, you can end your introduction section with the statement of the problem of your research that contains clear aims and objectives and also briefly describes (and justifies) your methodological approach.

When is the Rationale for Research Written?

The author can present the study rationale both before and after the research is conducted.

Before conducting research : The study rationale is a central component of the research proposal . It represents the plan of your work, constructed before the study is actually executed.
Once research has been conducted : After the study is completed, the rationale is presented in a research article or PhD dissertation to explain why you focused on this specific research question. When writing the study rationale for this purpose, the author should link the rationale of the research to the aims and outcomes of the study.

What to Include in the Study Rationale

Although every study rationale is different and discusses different specific elements of a study’s method or approach, there are some elements that should be included to write a good rationale. Make sure to touch on the following:

A summary of conclusions from your review of the relevant literature
What is currently unknown (gaps in knowledge)
Inconclusive or contested results from previous studies on the same or similar topic
The necessity to improve or build on previous research, such as to improve methodology or utilize newer techniques and/or technologies

There are different types of limitations that you can use to justify the need for your study. In applied/practical research, the justification for investigating something is always that an existing process/practice has a problem or is not satisfactory. Let’s say, for example, that people in a certain country/city/community commonly complain about hospital care on weekends (not enough staff, not enough attention, no decisions being made), but you looked into it and realized that nobody ever investigated whether these perceived problems are actually based on objective shortages/non-availabilities of care or whether the lower numbers of patients who are treated during weekends are commensurate with the provided services.

In this case, “lack of data” is your justification for digging deeper into the problem. Or, if it is obvious that there is a shortage of staff and provided services on weekends, you could decide to investigate which of the usual procedures are skipped during weekends as a result and what the negative consequences are.

In basic/theoretical research, lack of knowledge is of course a common and accepted justification for additional research—but make sure that it is not your only motivation. “Nobody has ever done this” is only a convincing reason for a study if you explain to the reader why you think we should know more about this specific phenomenon. If there is earlier research but you think it has limitations, then those can usually be classified into “methodological”, “contextual”, and “conceptual” limitations. To identify such limitations, you can ask specific questions and let those questions guide you when you explain to the reader why your study was necessary:

Methodological limitations

Did earlier studies try but failed to measure/identify a specific phenomenon?
Was earlier research based on incorrect conceptualizations of variables?
Were earlier studies based on questionable operationalizations of key concepts?
Did earlier studies use questionable or inappropriate research designs?

Contextual limitations

Have recent changes in the studied problem made previous studies irrelevant?
Are you studying a new/particular context that previous findings do not apply to?

Conceptual limitations

Do previous findings only make sense within a specific framework or ideology?

Study Rationale Examples

Let’s look at an example from one of our earlier articles on the statement of the problem to clarify how your rationale fits into your introduction section. This is a very short introduction for a practical research study on the challenges of online learning. Your introduction might be much longer (especially the context/background section), and this example does not contain any sources (which you will have to provide for all claims you make and all earlier studies you cite)—but please pay attention to how the background presentation , rationale, and problem statement blend into each other in a logical way so that the reader can follow and has no reason to question your motivation or the foundation of your research.

Background presentation

Since the beginning of the Covid pandemic, most educational institutions around the world have transitioned to a fully online study model, at least during peak times of infections and social distancing measures. This transition has not been easy and even two years into the pandemic, problems with online teaching and studying persist (reference needed) .

While the increasing gap between those with access to technology and equipment and those without access has been determined to be one of the main challenges (reference needed) , others claim that online learning offers more opportunities for many students by breaking down barriers of location and distance (reference needed) .

Rationale of the study

Since teachers and students cannot wait for circumstances to go back to normal, the measures that schools and universities have implemented during the last two years, their advantages and disadvantages, and the impact of those measures on students’ progress, satisfaction, and well-being need to be understood so that improvements can be made and demographics that have been left behind can receive the support they need as soon as possible.

Statement of the problem

To identify what changes in the learning environment were considered the most challenging and how those changes relate to a variety of student outcome measures, we conducted surveys and interviews among teachers and students at ten institutions of higher education in four different major cities, two in the US (New York and Chicago), one in South Korea (Seoul), and one in the UK (London). Responses were analyzed with a focus on different student demographics and how they might have been affected differently by the current situation.

How long is a study rationale?

In a research article bound for journal publication, your rationale should not be longer than a few sentences (no longer than one brief paragraph). A dissertation or thesis usually allows for a longer description; depending on the length and nature of your document, this could be up to a couple of paragraphs in length. A completely novel or unconventional approach might warrant a longer and more detailed justification than an approach that slightly deviates from well-established methods and approaches.

Summary of the research design

Example research proposal introductions.

This topic outlines the steps in the introduction of the research proposal. As discussed in the first topic in this series of web resources, there are three key elements or conceptual steps within the main body of the research proposal. In this resource, these elements are referred to as the research justification, the literature review and the research design. These three steps also structure, typically, but not always in this order, the proposal introduction which contains an outline of the proposed research.

These steps pertain to the key questions of reviewers:

What problem or issue does the research address? (research justification)
How will the research contribute to existing knowledge? (the 'gap' in the literature, sometimes referred to as the research 'significance')
How will the research achieve its stated objectives? (the research design)

Reviewers look to find a summary of the case for the research in the introduction, which, in essence, involves providing summary answers to each of the questions above.

The introduction of the research proposal usually includes the following content:

a research justification or statement of a problem (which also serves to introduce the topic)
a summary of the key point in the literature review (a summary of what is known and how the research aims to contribute to what is known)
the research aim or objective
a summary of the research design
concise definitions of any contested or specialised terms that will be used throughout the proposal (provided the first time the term is used).

This topic will consider how to write about each of these in turn.

Signaling the topic in the first sentence

The first task of the research proposal is to signal the area of the research or 'topic' so the reader knows what subject will be discussed in the proposal. This step is ideally accomplished in the opening sentence or the opening paragraph of the research proposal. It is also indicated in the title of the research proposal. It is important not to provide tangential information in the opening sentence or title because this may mislead the reader about the core subject of the proposal.

A ‘topic’ includes:

the context or properties of the subject (the particular aspect or properties of the subject that are of interest).

Questions to consider in helping to clarify the topic:

What is the focus of my research?
What do I want to understand?
What domain/s of activity does it pertain to?
What will I investigate in order to shed light on my focus?

The research justification or the ‘problem’ statement

The goal of the first step of the research proposal is to get your audience's attention; to show them why your research matters, and to make them want to know more about your research. The first step within the research proposal is sometimes referred to as the research justification or the statement of the 'problem'. This step involves providing the reader with critical background or contextual information that introduces the topic area, and indicates why the research is important. Research proposals often open by outlining a central concern, issue, question or conundrum to which the research relates.

The research justification should be provided in an accessible and direct manner in the introductory section of the research proposal. The number of words required to complete this first conceptual step will vary widely depending on the project.

Writing about the research justification, like writing about the literature and your research design, is a creative process involving careful decision making on your part. The research justification should lead up to the topic of your research and frame your research, and, when you write your thesis, exegesis or journal article conclusion, you will again return to the research justification to wrap up the implications of your research. That is to say, your conclusions will refer back to the problem and reflect on what the findings suggest about how we should treat the problem. For this reason, you may find the need to go back and reframe your research justification as your research and writing progresses.

The most common way of establishing the importance of the research is to refer to a real world problem. Research may aim to produce knowledge that will ultimately be used to:

advance national and organisational goals (health, clean environment, quality education),
improve policies and regulations,
manage risk,
contribute to economic development,
promote peace and prosperity,
promote democracy,
test assumptions (theoretical, popular, policy) about human behaviour, the economy, society,
understand human behaviour, the economy and social experience,
understand or critique social processes and values.

Examples of 'research problems' in opening sentences and paragraphs of research writing

Management The concept of meritocracy is one replicated and sustained in much discourse around organisational recruitment, retention and promotion. Women have a firm belief in the concept of merit, believing that hard work, education and talent will in the end be rewarded (McNamee and Miller, 2004). This belief in workplace meritocracy could in part be due to the advertising efforts of employers themselves, who, since the early 1990s, attempt to attract employees through intensive branding programs and aggressive advertising which emphasise equality of opportunity. The statistics, however, are less than convincing, with 2008 data from the Equal Employment for Women in the Workplace agency signalling that women are disproportionately represented in senior management levels compared to men, and that the numbers of women at Chief Executive Officer level in corporate Australia have actually decreased (Equal Opportunity for Women Agency, 2008). Women, it seems, are still unable to shatter the glass ceiling and are consistently overlooked at executive level.

Psychology Tension-type headache is extremely prevalent and is associated with significant personal and social costs.

Education One of the major challenges of higher education health programs is developing the cognitive abilities that will assist undergraduate students' clinical decision making. This is achieved by stimulating enquiry analysis, creating independent judgement and developing cognitive skills that are in line with graduate practice (Hollingworth and McLoughlin 2001; Bedard, 1996).

Visual arts In the East, the traditional idea of the body was not as something separate from the mind. In the West, however, the body is still perceived as separate, as a counterpart of the mind. The body is increasingly at the centre of the changing cultural environment, particularly the increasingly visual culture exemplified by the ubiquity of the image, the emergence of virtual reality, voyeurism and surveillance culture. Within the contemporary visual environment, the body's segregation from the mind has become more intense than ever, conferring upon the body a 'being watched' or 'manufacturable' status, further undermining the sense of the body as an integral part of our being.

Literature review summary

The next step following the research justification in the introduction is the literature review summary statement. This part of the introduction summarises the literature review section of the research proposal, providing a concise statement that signals the field of research and the rationale for the research question or aim.

It can be helpful to think about the literature review element as comprised of four parts. The first is a reference to the field or discipline the research will contribute to. The second is a summary of the main questions, approaches or accepted conclusions in your topic area in the field or discipline at present ('what is known'). This summary of existing research acts as a contrast to highlight the significance of the third part, your statement of a 'gap'. The fourth part rephrases this 'gap' in the form of a research question, aim, objective or hypothesis.

For example

Scholars writing about ... (the problem area) in the field of ... (discipline or sub-discipline, part one) have observed that ... ('what is known', part two). Others describe ... ('what is known', part two). A more recent perspective chronicles changes that, in broad outline, parallel those that have occurred in ... ('what is known', part two). This study differs from these approaches in that it considers ... ('gap', research focus, part three). This research draws on ... to consider ... (research objective, part four).

More information about writing these four parts of the literature review summary is provided below.

1. The 'field' of literature

The field of research is the academic discipline within which your research is situated, and to which it will contribute. Some fields grow out of a single discipline, others are multidisciplinary. The field or discipline is linked to university courses and research, academic journals, conferences and other academic associations, and some book publishers. It also describes the expertise of thesis supervisors and examiners.

The discipline defines the kinds of approaches, theories, methods and styles of writing adopted by scholars and researchers working within them.

For a list of academic disciplines have a look at the wikipedia site at: https://en.wikipedia.org/wiki/List_of_academic_disciplines

The field or discipline is not the same as the topic of the research. The topic is the subject matter or foci of your research. Disciplines or 'fields' refer to globally recognised areas of research and scholarship.

The field or discipline the research aims to contribute to can be signalled in a few key words within the literature review summary, or possibly earlier withn the research justification.

Sentence stems to signal the field of research

Within the field of ... there is now agreement that ... .
The field of ... is marked by ongoing debate about ... .
Following analysis of ... the field of ... turned to an exploration of ... .

2. A summary of contrasting areas of research or what is 'known'

The newness or significance of what you are doing is typically established in a contrast or dialogue with other research and scholarship. The 'gap' (or hole in the donut) only becomes apparent by the surrounding literature (or donut). Sometimes a contrast is provided to show that you are working in a different area to what has been done before, or to show that you are building on previous work, or perhaps working on an unresolved issue within a discipline. It might also be that the approaches of other disciplines on the same problem area or focus are introduced to highlight a new angle on the topic.

3. The summary of the 'gap' in the literature

The 'gap' in the field typically refers to the explanation provided to support the research question. Questions or objectives grow out of areas of uncertainty, or gaps, in the field of research. In most cases, you will not know what the gap in knowledge is until you have reviewed the literature and written up a good part of the literature review section of the proposal. It is often not possible therefore to confidently write the 'gap' statement until you have done considerable work on the literature review. Once your literature review section is sufficiently developed, you can summarise the missing piece of knowledge in a brief statement in the introduction.

Sentence stems for summarising a 'gap' in the literature

Indicate a gap in the previous research by raising a question about it, or extending previous knowledge in some way:

However, there is little information/attention/work/data/research on … .
However, few studies/investigations/researchers/attempt to … .

Often steps two and three blend together in the same sentence, as in the sentence stems below.

Sentence stems which both introduce research in the field (what is 'known') and summarise a 'gap'

The research has tended to focus on …(introduce existing field foci), rather than on … ('gap').
These studies have emphasised that … …(introduce what is known), but it remains unclear whether … ('gap').
Although considerable research has been devoted to … (introduce field areas), rather less attention has been paid to … ('gap').

The 'significance' of the research

When writing the research proposal, it is useful to think about the research justification and the ‘gap in the literature’ as two distinct conceptual elements, each of which must be established separately. Stating a real world problem or outlining a conceptual or other conundrum or concern is typically not, in itself, enough to justify the research. Similarly, establishing that there is a gap in the literature is often not enough on its own to persuade the reader that the research is important. In the first case, reviewers may still wonder ‘perhaps the problem or concern has already been addressed in the literature’, or, in the second, ‘so little has been done on this focus, but perhaps the proposed research is not important’? The proposal will ideally establish that the research is important, and that it will provide something new to the field of knowledge.

In effect, the research justification and the literature review work together to establish the benefit, contribution or 'significance' of the research. The 'significance' of the research is established not in a statement to be incorporated into the proposal, but as something the first two sections of the proposal work to establish. Research is significant when it pertains to something important, and when it provides new knowledge or insights within a field of knowledge.

4. The research aim or objective

The research aim is usually expressed as a concise statement at the close of the literature review. It may be referred to as an objective, a question or an aim. These terms are often used interchangeably to refer to the focus of the investigation. The research focus is the question at the heart of the research, designed to produce new knowledge. To avoid confusing the reader about the purpose of the research it is best to express it as either an aim, or an objective, or a question. It is also important to frame the aims of the research in a succinct manner; no more than three dot points say. And the aim/objective/question should be framed in more or less the same way wherever it appears in the proposal. This ensures the research focus is clear.

Language use

Research generally aims to produce knowledge, as opposed to say recommendations, policy or social change. Research may support policy or social change, and eventually produce it in some of its applications, but it does not typically produce it (with the possible exception of action research). For this reason, aims and objectives are framed in terms of knowledge production, using phrases like:

to increase understanding, insight, clarity;
to evaluate and critique;
to test models, theory, or strategies.

These are all knowledge outcomes that can be achieved within the research process.

Reflecting your social philosophy in the research aim

A well written research aim typically carries within it information about the philosophical approach the research will take, even if the researcher is not themselves aware of it, or if the proposal does not discuss philosophy or social theory at any length. If you are interested in social theory, you might consider framing your aim such that it reflects your philosophical or theoretical approach. Since your philosophical approach reflects your beliefs about how 'valid' knowledge can be gained, and therefore the types of questions you ask, it follows that it will be evident within your statement of the research aim. Researchers, variously, hold that knowledge of the world arises through:

observations of phenomena (measurements of what we can see, hear, taste, touch);
the interactions between interpreting human subjects and objective phenomena in the world;
ideology shaped by power, which we may be unconscious of, and which must be interrogated and replaced with knowledge that reflects people's true interests;
the structure of language and of the unconscious;
the play of historical relations between human actions, institutional practices and prevailing discourses;
metaphoric and other linguistic relations established within language and text.

The philosophical perspective underpinning your research is then reflected in the research aim. For example, depending upon your philosophical perspective, you may aim to find out about:

observable phenomenon or facts;
shared cultural meanings of practices, rituals, events that determine how objective phenomena are interpreted and experienced;
social structures and political ideologies that shape experience and distort authentic or empowered experience;
the structure of language;
the historical evolution of networks of discursive and extra-discursive practices;
emerging or actual phenomenon untainted by existing representation.

You might check your aim statement to ensure it reflects the philosophical perspective you claim to adopt in your proposal. Check that there are not contradictions in your philosophical claims and that you are consistent in your approach. For assistance with this you may find the Social philosophy of research resources helpful.

Sentence stems for aims and objectives

The purpose of this research project is to … .
The purpose of this investigation is to … .
The aim of this research project is to … .
This study is designed to … .

The next step or key element in the research proposal is the research design. The research design explains how the research aims will be achieved. Within the introduction a summary of the overall research design can make the project more accessible to the reader.

The summary statement of the research design within the introduction might include:

the method/s that will be used (interviews, surveys, video observation, diary recording);
if the research will be phased, how many phases, and what methods will be used in each phase;
brief reference to how the data will be analysed.

The statement of the research design is often the last thing discussed in the research proposal introduction.

NB. It is not necessary to explain that a literature review and a detailed ouline of the methods and methodology will follow because academic readers will assume this.

Title: Aboriginal cultural values and economic sustainability: A case study of agro-forestry in a remote Aboriginal community

Further examples can be found at the end of this topic, and in the drop down for this topic in the left menu.

In summary, the introduction contains a problem statement, or explanation of why the research is important to the world, a summary of the literature review, and a summary of the research design. The introduction enables the reviewer, as well as yourself and your supervisory team, to assess the logical connections between the research justification, the 'gap' in the literature, research aim and the research design without getting lost in the detail of the project. In this sense, the introduction serves as a kind of map or abstract of the proposed research as well as of the main body of the research proposal.

The following questions may be useful in assessing your research proposal introduction.

Have I clearly signalled the research topic in the key words and phrases used in the first sentence and title of the research proposal?
Have I explained why my research matters, the problem or issue that underlies the research in the opening sentences, paragraphs and page/s?
Have I used literature, examples or other evidence to substantiate my understanding of the key issues?
Have I explained the problem in a way that grabs the reader’s attention and concern?
Have I indicated the field/s within which my research is situated using key words that are recognised by other scholars?
Have I provided a summary of previous research and outlined a 'gap' in the literature?
Have I provided a succinct statement of the objectives or aims of my research?
Have I provided a summary of the research phases and methods?

The rationale for one’s research is the justification for undertaking a given study. It states the reason(s) why a researcher chooses to focus on the topic in question, including what the significance is and what gaps the research intends to fill. In short, it is an explanation that rationalises the need for the study. The rationale is typically followed by a hypothesis/ research question (s) and the study objectives.

When is the rationale for research written?

The rationale of a study can be presented both before and after the research is conducted.

Before : The rationale is a crucial part of your research proposal , representing the plan of your work as formulated before you execute your study.
After : Once the study is completed, the rationale is presented in a research paper or dissertation to explain why you focused on the particular question. In this instance, you would link the rationale of your research project to the study aims and outcomes.

Basis for writing the research rationale

The study rationale is predominantly based on preliminary data . A literature review will help you identify gaps in the current knowledge base and also ensure that you avoid duplicating what has already been done. You can then formulate the justification for your study from the existing literature on the subject and the perceived outcomes of the proposed study.

Length of the research rationale

In a research proposal or research article, the rationale would not take up more than a few sentences . A thesis or dissertation would allow for a longer description, which could even run into a couple of paragraphs . The length might even depend on the field of study or nature of the experiment. For instance, a completely novel or unconventional approach might warrant a longer and more detailed justification.

Basic elements of the research rationale

Every research rationale should include some mention or discussion of the following:

An overview of your conclusions from your literature review
Gaps in current knowledge
Inconclusive or controversial findings from previous studies
The need to build on previous research (e.g. unanswered questions, the need to update concepts in light of new findings and/or new technical advancements).

Example of a research rationale

Note: This uses a fictional study.

Abc xyz is a newly identified microalgal species isolated from fish tanks. While Abc xyz algal blooms have been seen as a threat to pisciculture, some studies have hinted at their unusually high carotenoid content and unique carotenoid profile. Carotenoid profiling has been carried out only in a handful of microalgal species from this genus, and the search for microalgae rich in bioactive carotenoids has not yielded promising candidates so far. This in-depth examination of the carotenoid profile of Abc xyz will help identify and quantify novel and potentially useful carotenoids from an untapped aquaculture resource .

In conclusion

It is important to describe the rationale of your research in order to put the significance and novelty of your specific research project into perspective. Once you have successfully articulated the reason(s) for your research, you will have convinced readers of the importance of your work!

This concluding module attempts to synthesize the key learning points discussed during the course of the previous ten sets of modules on methodology and biostatistics. The objective of this module is to discuss how to present a model research proposal, based on whatever was discussed in the preceding modules. The lynchpin of a research proposal is the protocol, and the key component of a protocol is the study design. However, one must not neglect the other areas, be it the project summary through which one catches the eyes of the reviewer of the proposal, or the background and the literature review, or the aims and objectives of the study. Two critical areas in the “methods” section that cannot be emphasized more are the sampling strategy and a formal estimation of sample size. Without a legitimate sample size, none of the conclusions based on the statistical analysis would be valid. Finally, the ethical parameters of the study should be well understood by the researchers, and that should get reflected in the proposal.

As we reach the end of an exhaustive module encompassing research methods and biostatistics, we need to summarize and synthesize the key learning points, to demonstrate how one may utilize the different sections of the module to undertake research projects of different kinds. After all, the practical purpose behind publishing such a module is to facilitate the preparation of high quality research proposals and protocols. This concluding part will make an attempt to provide a window to the different sections of the module, underlining the various aspects of design and analysis needed to formulate protocols applicable to different kinds of clinical research in dermatology.

Components of a Research Proposal

The goal of a research proposal is to present and justify the need to study a research problem and to present the practical ways in which the proposed study should be conducted. A research proposal is generally meant to be presented by an investigator to request an agency or a body to support research work in the form of grants. The vast majority of research proposals, in India, however, are not submitted to agency or body for grants, simply because of the paucity of such agencies, bodies, and research grants. Most are academic research proposals, self-financed, and submitted to scientific and ethics committee of an institution. The parts of a proposal include the title page, abstract/project summary, table of contents, introduction, background and review of literature, and the research protocol.

The title page should contain the personal data pertaining to the investigators, and title of the project, which should be concise and comprehensive at the same time. The table of contents, strictly speaking, is not necessary for short proposals. The introduction includes a statement of the problem, purpose, and significance of the research.

The protocol is the document that specifies the research plan. It is the single most important quality control tool for all aspects of a clinical research. It is the instrument where the researcher explains how data will be collected, including the calculation for estimating sample size, and what outcome variables to measure.

A complete clinical research protocol includes the following:

Study design

Precise definition of the disease or problem
Completely defined prespecified primary and secondary outcome measures, including how and when these will be assessed
Clear description of variables
Well-defined inclusion and exclusion criteria
Efficacy and safety parameters
Whenever applicable, stopping guidelines and parameters of interim analyses
Sample size calculation
Randomization details
Plan of statistical analysis
Detailed description of interventions
A chronogram of research flow (Gantt chart)
Informed consent document
Clinical research form
Details of budget; and
References.

Project Summary

The project summary is a brief document that consists of an overview, and discusses the intellectual merits, and broader impacts of the research project. Each of these three sections is required to be present and must be clearly defined. The project summary is one of the most important parts of the proposal. It is likely the first thing a reviewer will read, and is the investigators’ best chance to grab their interest, and convince them of the importance, and quality, of their research before they even read the proposal. Though it is the first proposal element in order, many applicants prefer to write the project summary last, after writing the protocol. This allows the writer to better avoid any inconsistencies between the two.

The overview specifies the research goal and it should demonstrate that this goal fits with the principal investigator's long-term research goals. It should specify the proposed research approach and the educational goal of the research project.

The intellectual merits (the contribution your research will make to your field) should specify the current state of knowledge in the field, and where it is headed. It should also clarify what your research will add to the state of knowledge in the field. Furthermore, important to state is what your research will do to enhance or enable other researches in the field. Finally, one should answer why your research is important for the advancement of the field.

The broader impacts (the contribution the research will make to the society) should answer the questions on the benefit to the society at large from the research, and the possible applications of the research, and why the general public would care. It should also clarify how the research can benefit the site of research (medical college or university, etc.) and the funding agency.

Background and Review of Literature

This is an important component of the research protocol. The review should discuss all the relevant literature, the method used in the literature, the lacunae in the literature, and justify the proposed research. We have provided a list of the useful databases in the section on systematic reviews and meta-analysis (Setia, 2017). Some of these are PubMed, Cochrane database, EMBASE, and LILACS.

Provide a critical analysis of the literature

The researcher should not provide a descriptive analysis of literature. For instance, the literature reviews should not be a list of one article followed by the next article. It should be a critical analysis of literature.

A study by XXXX et al . found that the prevalence of psoriasis was 20%. It was a hospital-based study conducted in North India. The prevalence was 35% in males and 12% in females.

Another study by YYYYY et al . found that the prevalence of psoriasis was 14%. The study was conducted in a private clinic in North India. The prevalence was 8% in males and 18% in females.

A third study by ZZZZZ et al . found that the prevalence of psoriasis was 5%. This study was a community-based study. The prevalence was 7% in males and 3% in females.

In this type of review, the researcher has described all the studies. However, it is useful to understand the findings of these three studies and summarize them in researcher's own words.

A possible option can be “ The reported prevalence of psoriasis in the Indian population varied from 5% to 20%. In general, it was higher in hospital-based studies and lower in community-based studies. There was no consistent pattern in the prevalence of psoriasis in males and females. Though some studies found the prevalence to be higher in males, others reported that females had a higher prevalence .”

Discuss the limitations and lacunae of these studies

The researcher should discuss the limitations of the studies. These could be the limitations that the authors have presented in the manuscript or the ones that the researcher has identified. Usually, the current research proposal should try to address the limitations of a previous study.

A study by BBBB et al : “ One of the main limitations of our study was the lack of objective criteria for assessing anemia in patients presenting with psoriasis. We classified the patients based on clinical assessment of pallor .”

The present proposal can mention “ Though previous studies have assessed the association between anemia and psoriasis, they have not used any objective criteria (such as hemoglobin or serum ferritin levels). Furthermore, pallor was evaluated by three clinicians; the authors have not described the agreement between these clinicians .”

In the above example, the authors have stated the limitation of their research in the manuscript. However, in the review of literature, the researcher has added another limitation. It is important to convince the reviewers that the researcher has read and understood the literature. It is also important that some or most of these lacunae should be addressed in the present proposal as far as possible.

Justify the present proposal by review

The researcher should adequately justify the present proposal based on the review of literature. The justification should not only be for the research question, but also the methods, study design, variables of interest, study instruments or measurements, and statistical methods of choice. Sometimes, the justification can be purely statistical. For example, all the previous studies have used cross-sectional data or cross-sectional analysis of longitudinal data in their manuscripts. The present proposal will use methods used for longitudinal data analysis. The researcher should justify the benefit of these methods over the previous statistical methods.

In short, the review should not be a “laundry list” of all the articles. The review should be able to convince the reader that the present research is required and it builds on the existing literature (either as a novel research question, new measurement of the outcome, a better study design, or advanced and appropriate statistical methods).

Kindly try to avoid this justification: “ It has not been done in our center .”

Aims and Objectives

The “aim” of the study is an overarching goal of the study. The objectives are measurable and help the researcher achieve the overall aim.

For example, the overall aim of our study is to assess the long-term health of patients of psoriasis.

The specific objectives are:

To record the changes in Psoriasis Area and Severity Index (PASI) score in patients with psoriasis over a period of 5 years
To study the side effects of medications in these patients over a period of 5 years.

It is important to clearly state the objectives, since the research proposal should be designed to achieve these objectives.

For example, the methods should describe the following:

How will the researcher answer the first objective?
Where will the researcher recruit the study participants (study site and population)?
Which patients of psoriasis will be recruited (inclusion and exclusion criteria)?
What will be the design of the study (cohort, etc.)?
What are all the variables to be measured to achieve the study outcomes (exposure and outcome variables)?
How will the researcher measure these variables (clinical evaluation, history, serological examination, etc.)?
How will the researcher record these data (clinical forms, etc.)?
How will the researcher analyze the data that have been collected?
Are there any limitations of these methods? If so, what has the researcher done to minimize the limitations?

All the ten modules on research methodology have to be read and grasped to plan and design any kind of research applicable to one's chosen field. However, some key areas have been outlined below with examples to appreciate the same in an easier manner.

The study setting must be specified. This should include both the geographical location and the population from which the study sample would be recruited.

“The study took place at the antiretroviral therapy clinic of Queen Elizabeth Central Hospital in Blantyre, Malawi, from January 2006 to April 2007. Blantyre is the major commercial city of Malawi, with a population of 1,000,000 and an estimated HIV prevalence of 27% in adults in 2004” (Ndekha et al ., 2009).

This is a perfect example of description of a study setting which underscores the importance of planning it in detail a priori .

Study population, sampling strategy, and sample size

Study population has to be clearly and precisely defined. For example, a study on atopic dermatitis may be conducted upon patients defined according to the UK Working Party's modified diagnostic criteria, or the Hanifin and Rajka's criteria, or some other criteria defined by the investigators. However, it should always be prespecified within the protocol.

Similarly, the eligibility criteria of the participants for the study must be explicit. One truism that is frequently forgotten is that the inclusion and exclusion criteria are mutually exclusive, and one is not the negative image of the other. Eligible cases are included according to a set of inclusion criteria, and this is followed by administration of the exclusion criteria. Thus, in fact, they can never be the negative image of each other.

“Eligible participants were all adults aged 18 or over with HIV who met the eligibility criteria for antiretroviral therapy according to the Malawian national HIV treatment guidelines (WHO clinical stage III or IV or any WHO stage with a CD4 count < 250/mm 3 ) and who were starting treatment with a BMI < 18.5. Exclusion criteria were pregnancy and lactation or participation in another supplementary feeding program” (Ndekha et al ., 2009).

To put in perspective the point we made about inclusion and exclusion criteria, in the above example, “age above 18 years” or “CD4 count >250/mm 3 ” cannot be exclusion criteria, as these have already been excluded.

Sampling strategy has been adequately discussed in the Module 5 of the Methodology series (Setia, 2016). A few points are worth repeating:

The sampling strategy should never be misrepresented. Example: If you have not done random sampling, no big deal. There are other legitimate sampling strategies available for your study. But once you have mentioned “random sampling” in your protocol, you cannot resort to purposive sampling
Sometimes, the researcher might want to know the characteristics of a certain problem within a specific population, without caring for generalizability of results. In such a scenario, purposive sampling may be resorted to
Nonprobability sampling methods such as consecutive consenting sampling or any such convenience sampling are perfectly legitimate and easy to do, particularly in case of dissertations where time and resources are limited.

Sample size is one of the most misunderstood, yet fundamentally important, issues among clinicians and has to be addressed once the study objectives have been set and the design has been finalized. Too small a sample means that there would be a failure to detect change following test intervention. A sample larger than necessary may also result in bad quality data. In either case, there would be ethical problems and wastage of resources. The researcher needs just enough samples to draw accurate inferences, which would be adequately powered (Panda, 2015).

Estimation of sample size has been dealt with adequately in the Module 5 biostatistics series (Hazra et al ., 2016), including the different mathematical derivations and the available software. Sample size determination is a statistical exercise based on the probability of errors in testing of hypothesis, power of the sample, and effect size. Although, relatively speaking, these are simple concepts to grasp, a large number of different study designs and analytical methods lead to a bewilderingly large number of formulae for determining sample size. Thus, the software are really handy and are becoming increasingly popular.

The study design defines the objectives and end points of the study, the type and manner of data collection, and the strategy of data analysis (Panda 2015). The different types of clinical studies have been depicted in Figure 1 . The suitability of various study designs vis-à-vis different types of research questions is summarized in Table 1 .

Research questions vis-a-vis study designs

An external file that holds a picture, illustration, etc.
Object name is IJD-62-443-g002.jpg

In our previous series of ten modules on methodology, we have discussed all these different kinds of studies and more. Some key issues that require reiteration are given below:

The control of a case–control study and that of a randomized controlled trial is more different from each other than chalk is from cheese. The former is an observational study, while the latter is an interventional one. Every study with a control group is not a case–control study. For a study to be classified as a case–control study, the study should be an observational study and the participants should be recruited based on their outcome status (Setia, 2016). Apparently, this is not so difficult to understand, yet even now we have publications which confuse between the different kinds of controls (Bhanja et al ., 2015)
Due to the fact that the outcome and exposure are assessed at the same time point in a cross-sectional study, it is pretty difficult, if not impossible, to derive causal relationships from such a study. At most, one may establish statistical association between exposures and outcomes by calculating the odds ratio. However, these associations must not be confused with causation.
It is generally said that a cohort design may not be efficient for rare outcomes. However, if the rare outcome is common in some exposures, it may be useful to follow a cohort design. For example, melanoma is a rare condition in India. Hence, if we follow individuals to study the incidence of melanoma, it may not be efficient. However, if we know that, in India, acral lentiginous melanoma is the most commonly reported variant, we should follow a cohort of individuals with acral lentiginous and study the incidence of melanoma in this group (Setia, 2016).

Clinical researchers should also be accustomed with observational designs beyond case–control, cohort, and cross-sectional studies. Sometimes, the unit of analysis has to be a group or aggregate rather than the individual. Consider the following example:

The government introduced the supplementation of salt with iodine for about 20 years. However, not all states have used the same level of iodine in salt. Certain hilly states have used higher quantities compared with other states. Incidentally, you read a report that high iodine levels are associated with psoriasis. You are intrigued to find if introduction of iodine has altered the picture of psoriasis in the country. You feel compelled to design a study to answer this question .

It is obvious that here the unit of study cannot be individuals, but a large population distributed in a certain geographical area. This is the domain of ecologic studies. An allied category of observational studies is named “natural experiments,” where the exposure is not assigned by the investigator (as in an interventional study), but through “natural processes.” These may be through changes in the existing regulations or public policies or, may be, through introduction of new laws (Setia, 2017).

Another category of research questions that cannot be satisfactorily captured by all the quantitative methods described earlier, like social stigma experienced by patients or their families with, say, vitiligo, leprosy, or sexually transmitted infections, are best dealt with by qualitative research. As can be seen by the examples given above, this is a type of research which is very relevant to medical research, yet to which the regular medical researcher has got a very poor exposure, if any. We shall encourage interested researchers to take a look at the 10 th Module of the Methodology series that specifically deals with qualitative research (Setia, 2017).

Clinical studies are experiments that are not conducted in laboratories but in controlled real-life settings on human subjects with some disease. Hence, designing a study involves many pragmatic considerations aside pure methodology. Thus, factors to consider when selecting a study design are objectives of the study, time frame, treatment duration, carryover effects, cost and logistics, patient convenience, statistical considerations, sample size, etc. (Panda, 2015).

Certain truisms regarding study designs should always be remembered: a study design has to be tailored to objectives. The same question may be answered by different designs. The optimum design has to be based on workforce, budgetary allocation, infrastructure, and clinical material that may be commanded by the researchers. Finally, no design is perfect, and there is no design to provide a perfect answer to all research questions relevant to a particular problem (Panda, 2015).

Variables of interest and collection of these variables

Data structure depends on the characteristics of the variables [ Figure 2 ]. A variable refers to a particular character on which a set of data are recorded. Data are thus the values of a variable (Hazra et al ., 2016).

An external file that holds a picture, illustration, etc.
Object name is IJD-62-443-g003.jpg

Types of data and variables (Source: Panda, 2015)

Quantitative data always have a proportional scale among values, and can be either discrete (e.g., number of moles) or continuous (e.g., age). Qualitative data can be either nominal (e.g., blood groups) or ordinal (e.g., Fitzpatrick's phototypes I-VI). Variables can be binary or dichotomous (male/female) or multinomial or polychotomous (homosexual/bisexual/heterosexual) (Panda, 2015).

Changing data scales is possible so that numerical data may become ordinal and ordinal data may become nominal. This may be done when the researcher is not confident about the accuracy of the measuring instrument, is unconcerned about the loss of fine detail, or where group numbers are not large enough to adequately represent a variable of interest. It may also make clinical interpretation easier (Hazra et al ., 2016).

The variables whose effects are observed on other variables are known as independent variables (e.g., risk factors). The latter kind of variables that change as a result of independent variables are known as dependent variables (i.e., outcome). Confounders are those variables that influence the relation between independent and dependent variables (e.g., the clinical effect of sunscreen used as part of a test intervention regimen in melasma). If the researcher fails to control or eliminate the confounder, it will damage the internal validity of an experiment (Panda, 2015).

Biostatistics begins with descriptive statistics that implies summarizing a collection of data from a sample or population. An excellent overview of descriptive statistics has been given in the Module 1 of the Biostatistics series (Hazra et al ., 2016). We would encourage every researcher to embark on designing and collecting data on their own to go through this particular module to have a clear idea on how to proceed further.

Statistical methods

As briefly discussed earlier, the “methods” section should also include a detailed description of statistical methods. It is best to describe the methods for each objective.

For example: Which statistical methods will the researcher use to study the changes in PASI score over time?

It is important to first identify the nature of the outcome – will it be linear or categorical?

It may be noticed that the PASI is a score and can range from 0 to 72. The researcher can measure the actual score and assess the changes in score. Thus, the researcher will use methods for statistical analysis of continuous data (such as means, standard deviations, t -test, or linear regressions)
However, the researcher may choose to cut off the PASI score at 60 (of course, there has to be justification!) and call it severe psoriasis. Thus, the researcher will have an outcome variable with two outcomes (Yes: >60 PASI, and No: <60 PASI). Thus, in this case, the researcher will use methods for statistical analysis of categorical data (proportions, Chi-square test, or logistic regression models).

The statistical methods have been described in detail in the Biostatistics section of the series. The reader is encouraged to read all the sections to understand these methods. However, the key points to remember are:

Identify the nature of the outcome for each objective
Describe the statistical methods separately for each objective
Identify the methods to handle confounding and describe them in the statistical methods
If the researcher is using advanced statistical methods or specific tools, please provide reference to these methods
Provide the name of the statistical software (including the version) that will be used for data analysis in the present study
Do not provide a laundry list of all the statistical methods. It just shows that the researcher has not understood the relevance of statistics in the study design.

Multivariate models

In general, multivariate analyses are used in studies and research proposals. These analyses are useful to adjust for confounding (though these are also useful to test for interaction, we shall discuss confounding in this section). For example, we propose to compare two different types of medications in psoriasis. We have used secondary clinical data for this study. The outcome of interest is PASI score. We have collected data on the type of medication, age, sex, and alcohol use. When we compare the PASI score in these two groups, we will use t -test (if linear comparison) or Chi-square test (if PASI is categorized – as described earlier). However, it is possible that age, sex, and alcohol use may also play a role in the clinical progression of psoriasis (which is measured as PASI score). Thus, the researcher would like to account for differences in these variables in the two groups. This can be done using multivariate analytical methods (such as linear regression for continuous variables and logistic regression for categorical dichotomous variables). This is a type of mathematical model in which we include multiple variables: the main explanatory variable (type of drug in this study) and potential confounders (age, sex, and alcohol use in this study). Thus, the outcome (PASI score) after multivariate analyses will be “adjusted” for age, sex, and alcohol use after multivariate analysis. We would like to encourage the readers to consult a statistician for these methods.

TRIVIA: The singular for “data” is “datum,” just as “stratum” is the singular for “strata.” Thus, “ data were analyzed …,” “ data were collected …,” and “ data have been ….”

Clinical Record Forms

We have discussed designing of questionnaires and clinical record forms (CRFs) in detail in two modules. We shall just highlight the most important aspects in this part. The CRF is an important part of the research protocol. The CRF should include all the variables of interest in the study. Thus, it is important to make a list of all parameters of interest before working on the CRF. This can be done by a thorough review of literature and discussion with experts. Once the questionnaire/CRF has been designed, the researcher should pilot it and change according to the feedback from the participants and one's own experience while administering the questionnaire or recording data in the CRF. The CRF should use coded responses (for close-ended questions), this will help in data entry and analysis. If the researcher has developed a scale, the reliability and validity should be tested (methods have been discussed in earlier sections). The CRF can be paper based or computer based (it will depend on the resources).

It is very important to describe the ethics for the present study. It should not be restricted to “ The study will be evaluated by an Institutional Review Committee …” The researcher should demonstrate that s/he has understood the various ethical issues in the present study. The three core principles for ethics are: autonomy (the participants have a right to decide whether to participate in the study or opt out), beneficence/nonmaleficence (the study should not be harmful to participants and the risk–benefit ratio should be adequately understood and described), and justice (all the risks and benefits of the present study should be equally distributed).

The researcher should try to address these issues in the section of “Ethics.” Currently, the National Institutes of Health has proposed the following seven principles of “Ethics in Clinical Research:” social and clinical value, scientific validity, fair subject selection, favorable risk–benefit ratio, independent review, informed consent, and respect for potential and enrolled subjects. The Indian Council of Medical Research has also published guidelines to conduct biomedical research in India. We strongly encourage the readers to be familiar with these guidelines. Furthermore, the researchers should keep themselves updated with changes in these regulations. If it is a clinical trial, the researcher should also be familiar with Schedule Y and Consent form requirements for these types of clinical trials.

Concluding Remarks

This module has been designed as a comprehensive guide for a dermatologist to enable him/her to embark on the exciting journey of designing studies of almost any kind that can be thought to be of relevance to clinical dermatology. There has been a conscious attempt to customize the discussion on design and analysis keeping not only dermatology, but also Indian conditions in mind. However, the module can be of help to any medical doctor embarking on the path to medical research. As contributors, it is our ardent hope that this module might act as a catalyst of good-quality research in the field of dermatology and beyond in India and elsewhere.

Bibliography

7 Examples of Justification (of a project or research)

The justification to the part of a research project that sets out the reasons that motivated the research. The justification is the section that explains the importance and the reasons that led the researcher to carry out the work.

The justification explains to the reader why and why the chosen topic was investigated. In general, the reasons that the researcher can give in a justification may be that his work allows to build or refute theories; bring a new approach or perspective on the subject; contribute to the solution of a specific problem (social, economic, environmental, etc.) that affects certain people; generate meaningful and reusable empirical data; clarify the causes and consequences of a specific phenomenon of interest; among other.

Among the criteria used to write a justification, the usefulness of the research for other academics or for other social sectors (public officials, companies, sectors of civil society), the significance in time that it may have, the contribution of new research tools or techniques, updating of existing knowledge, among others. Also, the language should be formal and descriptive.

Examples of justification

This research will focus on studying the reproduction habits of salmon in the Mediterranean region of Europe, since due to recent ecological changes in the water and temperatures of the region produced by human economic activity , the behavior of these animals has been modified. Thus, the present work would allow to show the changes that the species has developed to adapt to the new circumstances of its ecosystem, and to deepen the theoretical knowledge about accelerated adaptation processes, in addition to offering a comprehensive look at the environmental damage caused by growth. unsustainable economic, helping to raise awareness of the local population.
We therefore propose to investigate the evolution of the theoretical conceptions of class struggle and economic structure throughout the work of Antonio Gramsci, since we consider that previous analyzes have overlooked the fundamentally dynamic and unstable conception of human society that is present. in the works of Gramsci, and that is of vital importance to fully understand the author’s thought.
The reasons that led us to investigate the effects of regular use of cell phones on the health of middle-class young people under 18 years of age are centered on the fact that this vulnerable sector of the population is exposed to a greater extent than the rest of society to risks that the continuous use of cell phone devices may imply, due to their cultural and social habits. We intend then to help alert about these dangers, as well as to generate knowledge that helps in the treatment of the effects produced by the abuse in the use of this technology.
We believe that by means of a detailed analysis of the evolution of financial transactions carried out in the main stock exchanges of the world during the period 2005-2010, as well as the inquiry about how financial and banking agents perceived the situation of the financial system, it will allow us to clarify the economic mechanisms that enable the development of an economic crisis of global dimensions such as the one that the world experienced since 2009, and thus improve the design of regulatory and counter-cyclical public policies that favor the stability of the local and international financial system.

By DiscoverPhDs
October 21, 2020

What is the Rationale of Research?

The term rationale of research means the reason for performing the research study in question. In writing your rational you should able to convey why there was a need for your study to be carried out. It’s an important part of your research paper that should explain how your research was novel and explain why it was significant; this helps the reader understand why your research question needed to be addressed in your research paper, term paper or other research report.

The rationale for research is also sometimes referred to as the justification for the study. When writing your rational, first begin by introducing and explaining what other researchers have published on within your research field.

Having explained the work of previous literature and prior research, include discussion about where the gaps in knowledge are in your field. Use these to define potential research questions that need answering and explain the importance of addressing these unanswered questions.

The rationale conveys to the reader of your publication exactly why your research topic was needed and why it was significant . Having defined your research rationale, you would then go on to define your hypothesis and your research objectives.

Final Comments

Defining the rationale research, is a key part of the research process and academic writing in any research project. You use this in your research paper to firstly explain the research problem within your dissertation topic. This gives you the research justification you need to define your research question and what the expected outcomes may be.

How to Write a Research Proposal | Examples & Templates

Published on October 12, 2022 by Shona McCombes and Tegan George. Revised on November 21, 2023.

A research proposal describes what you will investigate, why it’s important, and how you will conduct your research.

The format of a research proposal varies between fields, but most proposals will contain at least these elements:

Introduction

Literature review.

Research design

Reference list

While the sections may vary, the overall objective is always the same. A research proposal serves as a blueprint and guide for your research plan, helping you get organized and feel confident in the path forward you choose to take.

Research proposal purpose, research proposal examples, research design and methods, contribution to knowledge, research schedule, other interesting articles, frequently asked questions about research proposals.

Academics often have to write research proposals to get funding for their projects. As a student, you might have to write a research proposal as part of a grad school application , or prior to starting your thesis or dissertation .

In addition to helping you figure out what your research can look like, a proposal can also serve to demonstrate why your project is worth pursuing to a funder, educational institution, or supervisor.

Research proposal length

The length of a research proposal can vary quite a bit. A bachelor’s or master’s thesis proposal can be just a few pages, while proposals for PhD dissertations or research funding are usually much longer and more detailed. Your supervisor can help you determine the best length for your work.

One trick to get started is to think of your proposal’s structure as a shorter version of your thesis or dissertation , only without the results , conclusion and discussion sections.

Writing a research proposal can be quite challenging, but a good starting point could be to look at some examples. We’ve included a few for you below.

Example research proposal #1: “A Conceptual Framework for Scheduling Constraint Management”
Example research proposal #2: “Medical Students as Mediators of Change in Tobacco Use”

Like your dissertation or thesis, the proposal will usually have a title page that includes:

The proposed title of your project
Your supervisor’s name
Your institution and department

The first part of your proposal is the initial pitch for your project. Make sure it succinctly explains what you want to do and why.

Your introduction should:

Introduce your topic
Give necessary background and context
Outline your problem statement and research questions

To guide your introduction , include information about:

Who could have an interest in the topic (e.g., scientists, policymakers)
How much is already known about the topic
What is missing from this current knowledge
What new insights your research will contribute
Why you believe this research is worth doing

As you get started, it’s important to demonstrate that you’re familiar with the most important research on your topic. A strong literature review shows your reader that your project has a solid foundation in existing knowledge or theory. It also shows that you’re not simply repeating what other people have already done or said, but rather using existing research as a jumping-off point for your own.

In this section, share exactly how your project will contribute to ongoing conversations in the field by:

Comparing and contrasting the main theories, methods, and debates
Examining the strengths and weaknesses of different approaches
Explaining how will you build on, challenge, or synthesize prior scholarship

Following the literature review, restate your main objectives . This brings the focus back to your own project. Next, your research design or methodology section will describe your overall approach, and the practical steps you will take to answer your research questions.

To finish your proposal on a strong note, explore the potential implications of your research for your field. Emphasize again what you aim to contribute and why it matters.

For example, your results might have implications for:

Improving best practices
Informing policymaking decisions
Strengthening a theory or model
Challenging popular or scientific beliefs
Creating a basis for future research

Last but not least, your research proposal must include correct citations for every source you have used, compiled in a reference list . To create citations quickly and easily, you can use our free APA citation generator .

Some institutions or funders require a detailed timeline of the project, asking you to forecast what you will do at each stage and how long it may take. While not always required, be sure to check the requirements of your project.

Here’s an example schedule to help you get started. You can also download a template at the button below.

Download our research schedule template

If you are applying for research funding, chances are you will have to include a detailed budget. This shows your estimates of how much each part of your project will cost.

Make sure to check what type of costs the funding body will agree to cover. For each item, include:

Cost : exactly how much money do you need?
Justification : why is this cost necessary to complete the research?
Source : how did you calculate the amount?

To determine your budget, think about:

Travel costs : do you need to go somewhere to collect your data? How will you get there, and how much time will you need? What will you do there (e.g., interviews, archival research)?
Materials : do you need access to any tools or technologies?
Help : do you need to hire any research assistants for the project? What will they do, and how much will you pay them?

Once you’ve decided on your research objectives , you need to explain them in your paper, at the end of your problem statement .

Keep your research objectives clear and concise, and use appropriate verbs to accurately convey the work that you will carry out for each one.

I will compare …

A research aim is a broad statement indicating the general purpose of your research project. It should appear in your introduction at the end of your problem statement , before your research objectives.

Research objectives are more specific than your research aim. They indicate the specific ways you’ll address the overarching aim.

A PhD, which is short for philosophiae doctor (doctor of philosophy in Latin), is the highest university degree that can be obtained. In a PhD, students spend 3–5 years writing a dissertation , which aims to make a significant, original contribution to current knowledge.

A PhD is intended to prepare students for a career as a researcher, whether that be in academia, the public sector, or the private sector.

A master’s is a 1- or 2-year graduate degree that can prepare you for a variety of careers.

All master’s involve graduate-level coursework. Some are research-intensive and intend to prepare students for further study in a PhD; these usually require their students to write a master’s thesis . Others focus on professional training for a specific career.

Critical thinking refers to the ability to evaluate information and to be aware of biases or assumptions, including your own.

Like information literacy , it involves evaluating arguments, identifying and solving problems in an objective and systematic way, and clearly communicating your ideas.

The best way to remember the difference between a research plan and a research proposal is that they have fundamentally different audiences. A research plan helps you, the researcher, organize your thoughts. On the other hand, a dissertation proposal or research proposal aims to convince others (e.g., a supervisor, a funding body, or a dissertation committee) that your research topic is relevant and worthy of being conducted.
