A purpose statement is a vital component of any project, as it sets the tone for the entire piece of work. It tells the reader what the project is about, why it’s important, and what the writer hopes to achieve.

Part 1 Key Elements of a Purpose Statement

When writing a purpose statement, there are several key elements that you should keep in mind. These elements will help you to create a clear, concise, and effective statement that accurately reflects your goals and objectives.

1. The Problem or Opportunity

The first element of a purpose statement is the problem or opportunity that you are addressing. This should be a clear and specific description of the issue that you are trying to solve or the opportunity that you are pursuing.

2. The Target Audience

The second element is the target audience for your purpose statement. This should be a clear and specific description of the group of people who will benefit from your work.

3. The Solution

The third element is the solution that you are proposing. This should be a clear and specific description of the action that you will take to address the problem or pursue the opportunity.

4. The Benefits

The fourth element is the benefits that your solution will provide. This should be a clear and specific description of the positive outcomes that your work will achieve.

5. The Action Plan

The fifth element is the action plan that you will follow to implement your solution. This should be a clear and specific description of the steps that you will take to achieve your goals.

Part 2 How to Write a Purpose Statement Step-by-Step

Writing a purpose statement is an essential part of any research project. It helps to clarify the purpose of your study and provides direction for your research. Here are some steps to follow when writing a purpose statement:

• Start with a clear research question: The first step in writing a purpose statement is to have a clear research question. This question should be specific and focused on the topic you want to research.
• Identify the scope of your study: Once you have a clear research question, you need to identify the scope of your study. This involves determining what you will and will not include in your research.
• Define your research objectives: Your research objectives should be specific, measurable, achievable, relevant, and time-bound. They should also be aligned with your research question and the scope of your study.
• Determine your research design: Your research design will depend on the nature of your research question and the scope of your study. You may choose to use a qualitative, quantitative, or mixed-methods approach.
• Write your purpose statement: Your purpose statement should be a clear and concise statement that summarizes the purpose of your study. It should include your research question, the scope of your study, your research objectives, and your research design.

Research question: What are the effects of social media on teenage mental health?

Scope of study: This study will focus on teenagers aged 13-18 in the United States.

Research objectives: To determine the prevalence of social media use among teenagers, to identify the types of social media used by teenagers, to explore the relationship between social media use and mental health, and to provide recommendations for parents, educators, and mental health professionals.

Research design: This study will use a mixed-methods approach, including a survey and interviews with teenagers and mental health professionals.

Purpose statement: The purpose of this study is to examine the effects of social media on teenage mental health among teenagers aged 13-18 in the United States. The study will use a mixed-methods approach, including a survey and interviews with teenagers and mental health professionals. The research objectives are to determine the prevalence of social media use among teenagers, to identify the types of social media used by teenagers, to explore the relationship between social media use and mental health, and to provide recommendations for parents, educators, and mental health professionals.

Part 3 Section 1: Identifying Your Goals

Before you start writing your purpose statement, it’s important to identify your goals. To do this, ask yourself the following questions:

• What do I want to achieve?
• What problem do I want to solve?
• What impact do I want to make?

Once you have a clear idea of your goals, you can start crafting your purpose statement. Your purpose statement should be a clear and concise statement that outlines the purpose of your work.

For example, if you’re writing a purpose statement for a business, your statement might look something like this:

“Our purpose is to provide high-quality products and services that improve the lives of our customers and contribute to the growth and success of our company.”

If you’re writing a purpose statement for a non-profit organization, your statement might look something like this:

“Our purpose is to improve the lives of underserved communities by providing access to education, healthcare, and other essential services.”

Remember, your purpose statement should be specific, measurable, and achievable. It should also be aligned with your values and goals, and it should inspire and motivate you to take action.

Part 4 Section 2: Defining Your Audience

Once you have established the purpose of your statement, it’s important to consider who your audience is. The audience for your purpose statement will depend on the context in which it will be used. For example, if you’re writing a purpose statement for a research paper, your audience will likely be your professor or academic peers. If you’re writing a purpose statement for a business proposal, your audience may be potential investors or clients.

Defining your audience is important because it will help you tailor your purpose statement to the specific needs and interests of your readers. You want to make sure that your statement is clear, concise, and relevant to your audience.

To define your audience, consider the following questions:

• Who will be reading your purpose statement?
• What is their level of knowledge or expertise on the topic?
• What are their needs and interests?
• What do they hope to gain from reading your purpose statement?

Once you have a clear understanding of your audience, you can begin to craft your purpose statement with their needs and interests in mind. This will help ensure that your statement is effective in communicating your goals and objectives to your readers.

For example, if you’re writing a purpose statement for a research paper on the effects of climate change on agriculture, your audience may be fellow researchers in the field of environmental science. In this case, you would want to make sure that your purpose statement is written in a way that is clear and concise, using technical language that is familiar to your audience.

Or, if you’re writing a purpose statement for a business proposal to potential investors, your audience may be less familiar with the technical aspects of your project. In this case, you would want to make sure that your purpose statement is written in a way that is easy to understand, using clear and concise language that highlights the benefits of your proposal.

The key to defining your audience is to put yourself in their shoes and consider what they need and want from your purpose statement.

Part 5 Section 3: Outlining Your Methods

After you have identified the purpose of your statement, it is time to outline your methods. This section should describe how you plan to achieve your goal and the steps you will take to get there. Here are a few tips to help you outline your methods effectively:

• Start with a general overview: Begin by providing a brief overview of the methods you plan to use. This will give your readers a sense of what to expect in the following paragraphs.
• Break down your methods: Break your methods down into smaller, more manageable steps. This will make it easier for you to stay organized and for your readers to follow along.
• Use bullet points: Bullet points can help you organize your ideas and make your methods easier to read. Use them to list the steps you will take to achieve your goal.
• Be specific: Make sure you are specific about the methods you plan to use. This will help your readers understand exactly what you are doing and why.
• Provide examples: Use examples to illustrate your methods. This will make it easier for your readers to understand what you are trying to accomplish.

Part 6 Section 4: Stating the Expected Outcomes

After defining the problem and the purpose of your research, it’s time to state the expected outcomes. This is where you describe what you hope to achieve by conducting your research. The expected outcomes should be specific and measurable, so you can determine if you have achieved your goals.

It’s important to be realistic when stating your expected outcomes. Don’t make exaggerated or false claims, and don’t promise something that you can’t deliver. Your expected outcomes should be based on your research question and the purpose of your study.

Here are some examples of expected outcomes:

• To identify the factors that contribute to employee turnover in the company.
• To develop a new marketing strategy that will increase sales by 20% within the next year.
• To evaluate the effectiveness of a new training program for improving customer service.
• To determine the impact of social media on consumer behavior.

When stating your expected outcomes, make sure they align with your research question and purpose statement. This will help you stay focused on your goals and ensure that your research is relevant and meaningful.

In addition to stating your expected outcomes, you should also describe how you will measure them. This could involve collecting data through surveys, interviews, or experiments, or analyzing existing data from sources such as government reports or industry publications.

Part 7 Purpose Statement Example for a Research Paper

If you are writing a research paper, your purpose statement should clearly state the objective of your study. Here is an example of a purpose statement for a research paper:

The purpose of this study is to investigate the effects of social media on the mental health of teenagers in the United States.

This purpose statement clearly states the objective of the study and provides a specific focus for the research.

Part 8 Purpose Statement Example For Personal Goals

When writing a purpose statement for your personal goals, it’s important to clearly define what you want to achieve and why. Here’s a template that can help you get started:

“I want to [goal] so that [reason]. I will achieve this by [action].”

Example: “I want to lose 10 pounds so that I can feel more confident in my body. I will achieve this by going to the gym three times a week and cutting out sugary snacks.”

Remember to be specific and realistic when setting your goals and actions, and to regularly review and adjust your purpose statement as needed.

Part 9 Purpose Statement Example For Business Objectives

If you’re writing a purpose statement for a business objective, this template can help you get started:

[Objective] [Action verb] [Target audience] [Outcome or benefit]

Here’s an example using this template:

Increase online sales by creating a more user-friendly website for millennial shoppers.

This purpose statement is clear and concise. It identifies the objective (increase online sales), the action verb (creating), the target audience (millennial shoppers), and the outcome or benefit (a more user-friendly website).

Part 10 Purpose Statement Example For an Essay

“The purpose of this essay is to examine the causes and consequences of climate change, with a focus on the role of human activities, and to propose solutions that can mitigate its impact on the environment and future generations.”

This purpose statement clearly states the subject of the essay (climate change), what aspects will be explored (causes, consequences, human activities), and the intended outcome (proposing solutions). It provides a clear roadmap for the reader and sets the direction for the essay.

Part 11 Purpose Statement Example For a Proposal

“The purpose of this proposal is to secure funding and support for the establishment of a community garden in [Location], aimed at promoting sustainable urban agriculture, fostering community engagement, and improving local access to fresh, healthy produce.”

Why this purpose statement is effective:

• The subject of the proposal is clear: the establishment of a community garden.
• The specific goals of the project are outlined: promoting sustainable urban agriculture, fostering community engagement, and improving local access to fresh produce.
• The overall objective of the proposal is evident: securing funding and support.

Part 12 Purpose Statement Example For a Report

“The purpose of this report is to analyze current market trends in the electric vehicle (EV) industry, assess consumer preferences and buying behaviors, and provide strategic recommendations to guide [Company Name] in entering this growing market segment.”

• The subject of the report is provided: market trends in the electric vehicle industry.
• The specific goals of the report are analysis of market trends, assessment of consumer preferences, and strategic recommendations.
• The overall objective of the report is clear: providing guidance for the company’s entry into the EV market.

Part 13 Purpose Statement Example For a Project

“The purpose of this project is to design and implement a new employee wellness program that promotes physical and mental wellbeing in the workplace.”

This purpose statement clearly outlines the objective of the project, which is to create a new employee wellness program. The program is designed to promote physical and mental wellbeing in the workplace, which is a key concern for many employers. By implementing this program, the company aims to improve employee health, reduce absenteeism, and increase productivity. The purpose statement is concise and specific, providing a clear direction for the project team to follow. It highlights the importance of the project and its potential benefits for the company and its employees.

Part 14 Purpose Statement Templates

When writing a purpose statement, it can be helpful to use a template to ensure that you cover all the necessary components:

Template 1: To [action] [target audience] in order to [outcome]

This template is a straightforward way to outline your purpose statement. Simply fill in the blanks with the appropriate information:

• The purpose of […] is
• To [action]: What action do you want to take?
• [Target audience]: Who is your target audience?
• In order to [outcome]: What outcome do you hope to achieve?

For example:

• The purpose of our marketing campaign is to increase brand awareness among young adults in urban areas, in order to drive sales and revenue growth.
• The purpose of our employee training program is to improve customer service skills among our frontline staff, in order to enhance customer satisfaction and loyalty.
• The purpose of our new product launch is to expand our market share in the healthcare industry, by offering a unique solution to the needs of elderly patients with chronic conditions.

Template 2: This [project/product] is designed to [action] [target audience] by [method] in order to [outcome].

This template is useful for purpose statements that involve a specific project or product. Fill in the blanks with the appropriate information:

• This [project/product]: What is your project or product?
• Is designed to [action]: What action do you want to take?
• By [method]: What method will you use to achieve your goal?
• This app is designed to provide personalized nutrition advice to athletes by analyzing their training data in order to optimize performance.

The purpose statement

The purpose statement is made up of three major components: (1) the motivation driving your dissertation; (2) the significance of the research you plan to carry out; and (3) the research questions you are going to address. Starting the first major chapter of your dissertation (usually Chapter One: Introduction ), the purpose statement establishes the intent of your entire dissertation. Just like a great song that needs a great "hook", the purpose statement needs to draw the reader in and keep their attention. This article explains the purpose of each of these three components that make up the purpose statement.

The "motivation" driving your dissertation

The "significance" of the research you plan to carry out, the "research questions" you are going to address.

Your choice of dissertation topic should be driven by some kind of motivation . This motivation is usually a problem or issue that you feel needs to be addressed or solved. This part of the purpose statement aims to answer the question: Why should we care? In other words, why should we be interested in the research problem or issue that you want to address?

The types of motivation that may drive your dissertation will vary depending on the subject area you are studying, as well as the specific dissertation topic you are interested in. However, some of the broad types of motivation that undergraduate and master's level dissertation students try to address are based around (a) individuals , (b) organisations , and/or (c) society .

Individuals face many problems and issues ranging from those associated with welfare , to health , prosperity , freedoms , security , and so on. From a health perspective, you may be concerned with the rise in childhood obesity and the potential need for regulation to combat the advertising of fast food to children. In terms of welfare and freedoms , you may be interested in the introduction of new legislation that aims to protect discrimination in the workplace, and its implications for small businesses.

Organisations also have a wide range of problems and issues that need to be addressed, whether relating to people , finances , operations , competition , regulations , and so forth. From a people perspective, you may be interested in how organisations use flexible working options to alleviate employee stress and burnout. In terms of regulations , you may be concerned with the growth in Internet piracy and the ways that organisations are dealing with such a threat.

Society is another lens through which you can view problems and issues that need to be addressed. These may relate to a wide range of societal risks or other problems and issues such as factory farming, the potential legalisation of marijuana, the health-related effects of talking on cell phones, and so forth. You may be interested in understanding individuals? views towards the potential legalisation of marijuana; or how these views are influenced by individuals? knowledge of the side-effects of marijuana use.

When communicating the motivation driving your dissertation to the reader, it is important to explain why the problem or issue you are addressing is interesting : that is, why should the reader care? It is not sufficient to simply state what the problem or issue is.

Whilst the motivation component of your purpose statement explains why the reader should care about your dissertation, the significance component justifies the value of the dissertation. In other words: What contribution will the dissertation make to the literature? Why should anyone bother to perform this research? What is its value?

Even though dissertations are rarely "ground-breaking" at the undergraduate or master's level (and are not expected to be), they should still be significant in some way. This component of the Introduction chapter, which follows the motivation section, should explain what this significance is. In this respect, your research may be significant in one of a number of ways. It may:

Capitalise on a recent event

Reflect a break from the past

Target a new audience

Address a flaw in a previous study

Expand a particular field of study

Help an individual, group, organisation, or community

When writing your purpose statement, you will need to explain the relationship between the motivation driving your dissertation and the significance of the research you plan to carry out. These two factors - motivation and significance - must be intrinsically linked; that is, you cannot have one without the other. The key point is that you must be able to explain the relationship between the motivation driving your dissertation and one (or more) of the types of significance highlighted in the bullets above.

The motivation and significance components of your Introduction chapter should signal to the reader the general intent of your dissertation. However, the research questions that you set out indicate the specific intent of your dissertation. In other words, your research questions tell the reader exactly what you intend to try and address (or answer) throughout the dissertation process.

In addition, since there are different types of research question (i.e., quantitative , qualitative and mixed methods research questions), it should be obvious from the significance component of your purpose statement which of these types of research question you intend to tackle [see the section, Research Questions , to learn more].

Having established the research questions you are going to address, this completes the purpose statement. At this point, the reader should be clear about the overall intent of your dissertation. If you are in the process of writing up your dissertation, we would recommend including a Chapter Summaries section after the Research Questions section of your Introduction chapter. This helps to let the reader know what to expect next from your dissertation.

Research question, purpose statement, hypothesis(es).

Here’s a good example of how to narrow your topic into a good research question:

• Too broad — Rural America
• Narrowed topic — Role of women in rural America?
• Research question — What is the central role of women in today’s farming communities?

If you’re asked to write a proposal before you begin your actual research, the proposal will contain a purpose statement that states in some detail what you want to learn about in your research project; it looks something like this:

• Ex.: “This study will examine the…”

Your purpose statement leads you to write a more refined thesis statement or hypothesis(es), an assertion that you can defend and support with evidence gathered in your literature review and research. Here are some examples:

• Ex.: “In the United States, government regulation plays an important role in the fight against air pollution.” Or, conversely,
• Ex.: “United States government regulation has little effect in the fight against air pollution.”

The type of design selected for your study depends on your research question(s), hypothesis(es), or problem.

You’ll use evidence you’ve gathered in your research to confirm — or reject — your hypothesis.

Writing a Statement of Purpose

Ask these questions:

What is it?

Why do I need to do it?

• It saves you valuable time and effort.

When and How to do it:

For example: One person was very concerned about air pollution and wanted to know if the government is doing anything to stop it. Her Statement of Purpose was this: I want to learn about what is being done by our government to stop air pollution. This Statement of Purpose will lead her to eventually write a Thesis Statement in which she will be able to make an assertion (a statement she can defend) and support it with the evidence she has gathered in her research. Her Thesis Statement may sound something like this: "In the United States, government regulation plays an important role in the fight against air pollution." Or, conversely, "United States government regulation has little effect in the fight against air pollution." Whichever the case, she will use the evidence she has gathered in her research to prove her Thesis Statement.

Make sure your Statement of Purpose is specific enough.

I think you probably get the idea by now. It may take a while to write your statement. If you are having trouble, ask a teacher or librarian for help.

How to Write a Research Statement

• Experimental Psychology

Task #1: Understand the Purpose of the Research Statement

The primary mistake people make when writing a research statement is that they fail to appreciate its purpose. The purpose isn’t simply to list and briefly describe all the projects that you’ve completed, as though you’re a museum docent and your research publications are the exhibits. “Here, we see a pen and watercolor self-portrait of the artist. This painting is the earliest known likeness of the artist. It captures the artist’s melancholic temperament … Next, we see a steel engraving. This engraving has appeared in almost every illustrated publication of Mary Shelley’s Frankenstein and has also appeared as the television studio back-drop for the …”

Similar to touring through a museum, we’ve read through research statements that narrate a researcher’s projects: “My dissertation examined the ways in which preschool-age children’s memory for a novel event was shaped by the verbal dialogue they shared with trained experimenters. The focus was on the important use of what we call elaborative conversational techniques … I have recently launched another project that represents my continued commitment to experimental methods and is yet another extension of the ways in which we can explore the role of conversational engagement during novel events … In addition to my current experimental work, I am also involved in a large-scale collaborative longitudinal project …”

Treating your research statement as though it’s a narrated walk through your vita does let you describe each of your projects (or publications). But the format is boring, and the statement doesn’t tell us much more than if we had the abstracts of each of your papers. Most problematic, treating your research statement as though it’s a narrated walk through your vita misses the primary purpose of the research statement, which is to make a persuasive case about the importance of your completed work and the excitement of your future trajectory.

Writing a persuasive case about your research means setting the stage for why the questions you are investigating are important. Writing a persuasive case about your research means engaging your audience so that they want to learn more about the answers you are discovering. How do you do that? You do that by crafting a coherent story.

Task #2: Tell a Story

Surpass the narrated-vita format and use either an Op-Ed format or a Detective Story format. The Op-Ed format is your basic five-paragraph persuasive essay format:

First paragraph (introduction):

• broad sentence or two introducing your research topic;
• thesis sentence, the position you want to prove (e.g., my research is important); and
• organization sentence that briefly overviews your three bodies of evidence (e.g., my research is important because a, b, and c).

Second, third, and fourth paragraphs (each covering a body of evidence that will prove your position):

• topic sentence (about one body of evidence);
• fact to support claim in topic sentence;
• another fact to support claim in topic sentence;
• another fact to support claim in topic sentence; and
• analysis/transition sentence.

Fifth paragraph (synopsis and conclusion):

• sentence that restates your thesis (e.g., my research is important);
• three sentences that restate your topic sentences from second, third, and fourth paragraph (e.g., my research is important because a, b, and c); and
• analysis/conclusion sentence.

Although the five-paragraph persuasive essay format feels formulaic, it works. It’s used in just about every successful op-ed ever published. And like all good recipes, it can be doubled. Want a 10-paragraph, rather than five-paragraph research statement? Double the amount of each component. Take two paragraphs to introduce the point you’re going to prove. Take two paragraphs to synthesize and conclude. And in the middle, either raise six points of evidence, with a paragraph for each, or take two paragraphs to supply evidence for each of three points. The op-ed format works incredibly well for writing persuasive essays, which is what your research statement should be.

The Detective Story format is more difficult to write, but it’s more enjoyable to read. Whereas the op-ed format works off deductive reasoning, the Detective Story format works off inductive reasoning. The Detective Story does not start with your thesis statement (“hire/retain/promote/ award/honor me because I’m a talented developmental/cognitive/social/clinical/biological/perception psychologist”). Rather, the Detective Story starts with your broad, overarching research question. For example, how do babies learn their native languages? How do we remember autobiographical information? Why do we favor people who are most similar to ourselves? How do we perceive depth? What’s the best way to treat depression? How does the stress we experience every day affect our long-term health?

Because it’s your research statement, you can personalize that overarching question. A great example of a personalized overarching question occurs in the opening paragraph of George Miller’s (1956) article, “The Magical Number Seven, Plus or Minus Two: Some Limits on Our Capacity for Processing Information.”

My problem is that I have been persecuted by an integer. For seven years this number has followed me around, has intruded in my most private data, and has assaulted me from the pages of our most public journals. This number assumes a variety of disguises, being sometimes a little larger and sometimes a little smaller than usual, but never changing so much as to be unrecognizable. The persistence with which this number plagues me is far more than a random accident. There is, to quote a famous senator, a design behind it, some pattern governing its appearances. Either there really is something unusual about the number or else I am suffering from delusions of persecution. I shall begin my case history by telling you about some experiments that tested how accurately people can assign numbers to the magnitudes of various aspects of a stimulus. …

In case you think the above opening was to a newsletter piece or some other low-visibility outlet, it wasn’t. Those opening paragraphs are from a Psych Review article, which has been cited nearly 16,000 times. Science can be personalized. Another example of using the Detective Story format, which opens with your broad research question and personalizes it, is the opening paragraph of a research statement from a chemist:

I became interested in inorganic chemistry because of one element: Boron. The cage structures and complexity of boron hydrides have fascinated my fellow Boron chemists for more than 40 years — and me for more than a decade. Boron is only one element away from carbon, yet its reactivity is dramatically different. I research why.

When truest to the genre of Detective Story format, the full answer to your introductory question won’t be available until the end of your statement — just like a reader doesn’t know whodunit until the last chapter of a mystery. Along the way, clues to the answer are provided, and false leads are ruled out, which keeps readers turning the pages. In the same way, writing your research statement in the Detective Story format will keep members of the hiring committee, the review committee, and the awards panel reading until the last paragraph.

Task #3: Envision Each Audience

The second mistake people make when writing their research statements is that they write for the specialist, as though they’re talking to another member of their lab. But in most cases, the audience for your research statement won’t be well-informed specialists. Therefore, you need to convey the importance of your work and the contribution of your research without getting bogged down in jargon. Some details are important, but an intelligent reader outside your area of study should be able to understand every word of your research statement.

Because research statements are most often included in academic job applications, tenure and promotion evaluations, and award nominations, we’ll talk about how to envision the audiences for each of these contexts.

Job Applications . Even in the largest department, it’s doubtful that more than a couple of people will know the intricacies of your research area as well as you do. And those two or three people are unlikely to have carte blanche authority on hiring. Rather, in most departments, the decision is made by the entire department. In smaller departments, there’s probably no one else in your research area; that’s why they have a search going on. Therefore, the target audience for your research statement in a job application comprises other psychologists, but not psychologists who study what you study (the way you study it).

Envision this target audience explicitly.Think of one of your fellow graduate students or post docs who’s in another area (e.g., if you’re in developmental, think of your friend in biological). Envision what that person will — and won’t — know about the questions you’re asking in your research, the methods you’re using, the statistics you’re employing, and — most importantly — the jargon that you usually use to describe all of this. Write your research statement so that this graduate student or post doc in another area in psychology will not only understand your research statement, but also find your work interesting and exciting.

Tenure Review . During the tenure review process, your research statement will have two target audiences: members of your department and, if your tenure case receives a positive vote in the department, members of the university at large. For envisioning the first audience, follow the advice given above for writing a research statement for a job application. Think of one of your departmental colleagues in another area (e.g., if you’re in developmental, think of your friend in biological). Write in such a way that the colleague in another area in psychology will understand every word  — and find the work interesting. (This advice also applies to writing research statements for annual reviews, for which the review is conducted in the department and usually by all members of the department.)

For the second stage of the tenure process, when your research statement is read by members of the university at large, you’re going to have to scale it down a notch. (And yes, we are suggesting that you write two different statements: one for your department’s review and one for the university’s review, because the audiences differ. And you should always write with an explicit target audience in mind.) For the audience that comprises the entire university, envision a faculty friend in another department. Think political science or economics or sociology, because your statement will be read by political scientists, economists, and sociologists. It’s an art to hit the perfect pitch of being understood by such a wide range of scholars without being trivial, but it’s achievable.

Award Nominations . Members of award selection committees are unlikely to be specialists in your immediate field. Depending on the award, they might not even be members of your discipline. Find out the typical constitution of the selection committee for each award nomination you submit, and tailor your statement accordingly.

Task #4: Be Succinct

When writing a research statement, many people go on for far too long. Consider three pages a maximum, and aim for two. Use subheadings to help break up the wall of text. You might also embed a well-designed figure or graph, if it will help you make a point. (If so, use wrap-around text, and make sure that your figure has its axes labeled.)

And don’t use those undergraduate tricks of trying to cram more in by reducing the margins or the font size. Undoubtedly, most of the people reading your research statement will be older than you, and we old folks don’t like reading small fonts. It makes us crabby, and that’s the last thing you want us to be when we’re reading your research statement.

Nice piece of information. I will keep in mind while writing my research statement

Thank you so much for your guidance.

HOSSEIN DIVAN-BEIGI

Absolutely agree! I also want to add that: On the one hand it`s easy to write good research personal statement, but on the other hand it`s a little bit difficult to summarize all minds and as result the main idea of the statement could be incomprehensible. It also seems like a challenge for those guys, who aren`t native speakers. That`s why you should prepare carefully for this kind of statement to target your goals.

How do you write an action research topic?? An then stAte the problem an purpose for an action research. Can I get an example on language development?? Please I need some help.

Thankyou I now have idea to come up with the research statement. If I need help I will inform you …

much appreciated

Just like Boote & Beile (2005) explained “Doctors before researchers” because of the importance of the dissertation literature review in research groundwork.

Graduate School Applications: Writing a Research Statement

Welcome to the Purdue OWL

What is a Research Statement?

A research statement is a short document that provides a brief history of your past research experience, the current state of your research, and the future work you intend to complete.

The research statement is a common component of a potential candidate’s application for post-undergraduate study. This may include applications for graduate programs, post-doctoral fellowships, or faculty positions. The research statement is often the primary way that a committee determines if a candidate’s interests and past experience make them a good fit for their program/institution.

What Should It Look Like?

Research statements are generally one to two single-spaced pages. You should be sure to thoroughly read and follow the length and content requirements for each individual application.

Your research statement should situate your work within the larger context of your field and show how your works contributes to, complicates, or counters other work being done. It should be written for an audience of other professionals in your field.

What Should It Include?

Your statement should start by articulating the broader field that you are working within and the larger question or questions that you are interested in answering. It should then move to articulate your specific interest.

The body of your statement should include a brief history of your past research . What questions did you initially set out to answer in your research project? What did you find? How did it contribute to your field? (i.e. did it lead to academic publications, conferences, or collaborations?). How did your past research propel you forward?

It should also address your present research . What questions are you actively trying to solve? What have you found so far? How are you connecting your research to the larger academic conversation? (i.e. do you have any publications under review, upcoming conferences, or other professional engagements?) What are the larger implications of your work?

Finally, it should describe the future trajectory on which you intend to take your research. What further questions do you want to solve? How do you intend to find answers to these questions? How can the institution to which you are applying help you in that process? What are the broader implications of your potential results?

Note: Make sure that the research project that you propose can be completed at the institution to which you are applying.

Other Considerations:

• What is the primary question that you have tried to address over the course of your academic career? Why is this question important to the field? How has each stage of your work related to that question?
• Include a few specific examples that show your success. What tangible solutions have you found to the question that you were trying to answer? How have your solutions impacted the larger field? Examples can include references to published findings, conference presentations, or other professional involvement.
• Be confident about your skills and abilities. The research statement is your opportunity to sell yourself to an institution. Show that you are self-motivated and passionate about your project.

Gre prep online guides and tips, 7 successful statement of purpose examples.

Not sure what graduate schools are looking for in a statement of purpose? Looking at successful graduate school statement of purpose samples can help! In this guide, we’ll orient you to what makes a great statement of purpose or letter of intent for graduate school. Then we’ll provide you with four successful statement of purpose examples from our graduate school experts. We’ll also provide analysis of what makes them successful. Finally, we’ll direct you to even more helpful examples that you can find online!

The Graduate School Statement of Purpose: An Overview

A statement of purpose (also called a letter of intent or a research statement) introduces your interests and experience to the admissions committee. For research-focused programs, like most PhDs and many master’s degrees, your statement of purpose will focus primarily on your past research experience and plans. For more professionally-focused graduate programs, your statement of purpose will primarily discuss how your pursuit of this professional program relates to your past experiences, and how you will use the skills from the program in your future career.

A statement of purpose for grad school is also where you sell the admissions committee on why you belong in their program specifically. Why do you fit there, and how does what they offer fit your interests?

What’s in a Great Grad School Statement of Purpose?

Here are the essential elements of a strong graduate school statement of purpose:

Clear Articulation of Goals and Interests

A strong statement of purpose will clearly and specifically lay out your goals in undertaking the program and what you hope to accomplish with the degree. Again, for a research-focused program, this will focus primarily on the research project(s) you want to undertake while you are there. For a more professional program, discuss what interests you within the professional field and what skills/knowledge you hope to gain through the program.

Quick side note: we've created the world's leading online GRE prep program that adapts to you and your strengths and weaknesses. Not sure what to study? Confused by how to improve your score? We give you minute by minute guide.

You don't NEED a prep program to get a great GRE score. But we believe PrepScholar is the best GRE prep program available right now , especially if you find it hard to organize your study schedule and don't know what to study .

Click here to learn how you can improve your GRE score by 7 points, guaranteed .

You should be as specific as possible in discussing what interests you. Use examples of particular phenomena, tools, or situations that you find exciting. If you are vague or say that everything in the field interests you, you run the risk of seeming unfocused or not actually that passionate.

Don’t worry that being too specific will box you into a particular research area or subfield during your entire tenure in graduate school. Your program understands that interests change—they won’t be pulling out your research statement to cross-reference with your dissertation proposal!

Evidence of Past Experience and Success

A great graduate school statement of purpose will also show programs that you have already been successful. They want applicants that will be able to follow through on their research/professional plans!

To this end, you’ll need to provide evidence of how your background qualifies you to pursue this program and your specific interests in the field. You’ll probably discuss your undergraduate studies and any professional experience you have. But be sure to draw on specific, vivid examples.  You might draw on your thesis, major projects you’ve worked on, papers you have written/published, presentations you’ve given, mentors you’ve worked with, and so on. This gives admissions committees concrete evidence that you are qualified to undertake graduate study!

Interest and Fit With the Program

The third essential ingredient to a great statement of purpose is to clearly lay out why you and the program are a good fit. You should be able to identify both specific reasons why your work fits with the program and why the program suits your work/interests! Are there particular professors you’d like to work with? Does the department have a strong tradition in a certain methodology or theory you’re interested in? Is there a particular facet to the curriculum that you’d like to experience?

Showing that you and the program are a match shows that you chose the program thoughtfully and have genuine interest in it. Programs want to admit students who aren’t just passionate about the field. They want students who are genuinely enthused about their specific program and positioned to get the most out of what they have to offer.

Strong Writing

The final essential piece of a strong statement of purpose or letter of intent is strong writing. Writing skills are important for all graduate programs. You’ll need to demonstrate that you can clearly and effectively communicate your ideas in a way that flows logically. Additionally, you should show that you know how to write in a way that is descriptive but concise. A statement of purpose shouldn’t ever be longer than two pages, even without a hard word limit.

Admissions committees for humanities programs may be a little more focused on writing style than admissions officers for STEM programs. But even in quantitative and science-focused fields, written communication skills are an essential part of graduate school. So a strong statement of purpose will always be effectively written. You’ll see this in our statement of purpose for graduate school samples.

Real, Successful Statement of Purpose Samples

In this section, we’ll present four successful graduate school statement of purpose examples from our graduate school experts, along with a brief commentary on each statement. These statements come from a diverse selection of program types to show you how the core essentials of a statement of purpose can be implemented differently for different fields.

Note: identifying information for these statements have been changed—except for example four, which is my statement.

• Statement of Purpose Sample One: Japanese Studies MA

This statement of purpose is notable for its great use of space and its vivid descriptions. The author is able to cram a lot into about a page. She discusses how she came to her two primary research interests (and how they are connected). She integrates this discussion of her interests with information on her past experiences and qualifications for pursuing the course of study. Finally, she includes details on her goals in pursuing the program and components of the program that interest her. Her examples are specific and fleshed-out. There’s a lot very cleverly included in a small amount of page space!

Additionally, the language is very vivid. Phrases like “evocative and visceral” and “steadily unraveling,” are eye-catching and intriguing. They demonstrate that she has the writing skills necessary to pursue both graduate study and her interest in translation.

• Statement of Purpose Sample Two: Music MM

This sample is fairly long, although at 12 point Times New Roman it’s under two pages single-spaced. The length of this statement is partially due to the somewhat expansive nature of the prompt, which asks what role music has played in the applicant’s life “to date.” This invites applicants to speak more about experiences further in the past (in the childhood and teen years) than is typical for a statement of purpose. Given that this is for a master’s degree in music, this is logical; musical study is typically something that is undertaken at a fairly young age.

This statement does an excellent job describing the student’s past experiences with music in great detail. The descriptions of the student’s past compositions and experiences performing new music are particularly vivid and intriguing.

This statement also lays out and elaborates on specific goals the student hopes to pursue through the program, as well as features particular to the program that interest the student (like particular professors).

• Statement of Purpose Sample Three: Economics PhD

One of the first things you’ll likely notice about this statement is that it’s a little on the longer side. However, at 12 point Times New Roman font and single-spaced, it still comes in under 2 pages (excluding references). It makes sense for a PhD statement of purpose sample to be longer than a master’s degree statement of purpose—there’s more to lay out in terms of research interests!

The writing style is fairly straightforward—there’s definitely a stronger focus on delivering content than flashy writing style. As Economics is a more quantitative-focused field, this is fine. But the writing is still well-organized, clear, and error-free.

The writer also gives numerous examples of their past work and experience, and shows off their knowledge of the field through references, which is a nice touch.

• Statement of Purpose Sample Four: History of the Book MA

This is actually my statement of purpose. It was for a program that I got accepted to but did not end up attending, for a Master’s in the History of the Book. You’ll notice that the two essay prompts essentially asked us to split our statement of purpose into two parts: the first prompt asked about our research interests and goals, and the second prompt asked about our relevant experience and qualifications.

I’ll keep my comments on this graduate school statement of purpose sample brief because I’ll do a deep dive on it in the next section. But looking back at my statement of purpose, I do a good job outlining what within the field interests me and clearly laying out how my past experiences have qualified me for the program.

Obviously this statement did its job, since I was accepted to the program. However, if I were to improve this statement, I’d change the cliche beginning  (“since I was a child”) and provide more specificity in what about the program interested me.

Deep Dive Analysis of a Sample Statement of Purpose for Graduate School

Next, we’ll do a paragraph by paragraph analysis of my statement, statement of purpose sample four. I’ll analyze its strengths and suggest ways I could shore up any weaknesses to make it even stronger.

Essay 1: Academic Interests

To refresh, here’s the first prompt: Please give a short statement that describes your academic interests, purpose, objectives and motivation in undertaking this postgraduate study. (max 3500 chars – approx. 500 words)

Paragraph 1

Since I was a child, my favorite thing has always been a book. Not just for the stories and information they contain, although that is a large part of it. Mostly, I have been fascinated by the concept of book as object—a tangible item whose purpose is to relate intangible ideas and images. Bookbindings and jackets, different editions, the marginalia in a used book—all of these things become part of the individual book and its significance, and are worth study and consideration. Books and their equivalent forms—perfect bound, scrolled, stone tablets, papyrus—have long been an essential part of material culture and are also one of our most significant sources of information about the human historical past. Through both the literal object of the book, the words contained thereon, and its relationship to other books—forms of context, text and intertext—we are able to learn and hopefully manage layers of information with which we would otherwise have no familiarity.

First, the good: this paragraph does a good job introducing my academic interest in the book-as-object, and shows off pre-existing knowledge both of the study of material culture and literary theory. Additionally, the language is engaging: the juxtaposition of “tangible” and “intangible” in the beginning and phrases like “perfect bound, scrolled, stone tablets, papyrus” lend life to the writing and keep the reader engaged.

If I were to go back and improve this paragraph, first, I would absolutely change the first sentence to something less cliche than talking about my childhood. I might try something like “My love of books is a multifaceted thing. I don’t only love them for the stories and….” Second, I would chill out on the em dashes a little bit. Three sets in one paragraph is a little excessive. Finally, I might actually cut this paragraph down slightly to make more room word-wise later in the statement to discuss what specific things about the program interest me.

Paragraph 2

Furthermore, blogs, webcomics, digital archives, e-readers, and even social media sites like tumblr and Facebook have revolutionized the concept of the book by changing how we share and transmit ideas and information, just as the Gutenberg printing press revolutionized the book all those years ago in the fifteenth century. Once again there has been an explosion both in who can send out information and who can receive it.

This paragraph briefly and effectively introduces my other main academic interest: how new technology has changed the concept of the book-as-object. The tie-back to the printing press is a nice touch; it’s a vivid example that shows that I’m aware of important historical moments in book history.

Paragraph 3

I am deeply interested in the preservation of the physical book, as I think it is an important part of human history (not to mention a satisfying sensory experience for the reader). However I am also very concerned with the digitization and organization of information for the modern world such that the book, in all of its forms, stays relevant and easy to access and use. Collections of books, archives, and information as stored in the world’s servers, libraries and museums are essential resources that need to be properly organized and administered to be fully taken advantage of by their audiences. My purpose in applying to the University of Edinburgh’s Material Culture and History of the Book is to gain the skills necessary to keep all forms of the book relevant and functional in an age when information can move more radically than ever before.

This paragraph actually has a focus problem. Since it covers two topics, I should split it into two paragraphs: one on the integration of my two interests, and one on my goals and interests in the program. I could also stand to expand on what features the program has that interest me: professors I’d like to work with, particular aspects of the curriculum, etc.

In spite of these things, however, this paragraph does a good job clearly integrating the two academic interests related to the book I introduced in the first two paragraphs. And the language is still strong —“satisfying sensory experience” is a great phrase. However, I’ve been using the word “information,” a lot; I might try to replace with appropriate synonyms (like “knowledge”) in a couple of places.

Paragraph 4

Additionally, I intend on pursuing a PhD in Library and Information Sciences upon completion of my master’s and I feel that this program while make me uniquely suited to approach library science from a highly academic and interdisciplinary perspective.

This final paragraph offers just quick touch on my future goals beyond the program. It’s typically fine for this to be relatively brief, as it is here, just so long as you can clearly identify some future goals.

Essay 2: Relevant Experience

The second prompt just asked me to describe my relevant knowledge, training, and skills.

As a folklore and mythology student, I have gained a robust understanding of material culture and how it relates to culture as a whole. I have also learned about the transmission of ideas, information, stories and pieces of lore among and between populations, which is an important component of book history. Folklore is also deeply concerned with questions of the literary vs. oral lore and the tendency for text to “canonize” folklore, and yet text can also question or invert canonized versions; along with this my studies in my focus field of religion and storytelling have been deeply concerned with intertextuality. One of my courses was specifically concerned with the Heian-period Japanese novel The Tale of Genji and questions of translation and representation in post-Heian picture scrolls and also modern translations and manga. In addition to broader cultural questions concerned with gender and spirituality both in historical Japan and now, we considered the relationships between different Genji texts and images.

This is a strong, focused paragraph. I relate my academic background in Folklore and Mythology to my interests in studying the book, as well as showing off some of my knowledge in the area. I also chose and elaborated on a strong example (my class on the Tale of Genji ) of my relevant coursework.

I also have work experience that lends itself to the study of the book. After my freshman year of college I interned at the Chicago History Museum. Though I was in the visitor services department I was exposed to the preservation and archival departments of the museum and worked closely with the education department, which sparked my interest in archival collections and how museums present collection information to the public. After my sophomore year of college and into my junior year, I worked at Harvard’s rare books library, Houghton. At Houghton I prepared curated collections for archival storage. These collections were mostly comprised of the personal papers of noteworthy individuals, categorized into alphabetical folders. This experience made me very process-oriented and helped me to understand how collections come together on a holistic basis.

This paragraph also has a clear focus: my past, relevant work experience. Discussing archival collections and presenting information to the public links the interests discussed in my first statement with my qualifications in my second statement. However, if I were to revise this paragraph, I would add some specific examples of the amazing things I worked on and handled at Houghton Library. In that job, I got to touch Oliver Cromwell’s death mask! An interesting example would make this paragraph really pop even more.

Finally, in my current capacity as an education mentor in Allston, a suburb of Boston, I have learned the value of book history and material culture from an educational perspective. As a mentor who designs curriculum for individual students and small groups, I have learned to highly value clearly organized and useful educational resources such as websites, iPad apps, and books as tools for learning. By managing and organizing collections in a way that makes sense we are making information accessible to those who need it.

This final paragraph discusses my current (at the time) work experience in education and how that ties into my interest in the history of the book. It’s an intriguing connection and also harkens back to my discussion of information availability in the paragraph three of the first statement. Again, if I were to amp up this statement even more, I might include a specific example of a book-based (or book technology-based) project I did with one of my students. I worked on things like bookbinding and making “illuminated manuscripts” with some of my students; those would be interesting examples here.

This statement is split into two parts by virtue of the two-prompt format. However, if I were to integrate all of this information into one unified statement of purpose, I would probably briefly introduce my research interests, go in-depth on my background, then circle back around to speak more about my personal interests and goals and what intrigues me about the program. There’s not really one correct way to structure a statement of purpose just so long as it flows well and paragraphs are structured in a logical way: one topic per paragraph, with a clear topic and concluding sentence.

More Statement of Purpose Examples

We’ve provided you with four great graduate school statement of purpose examples from our graduate school experts. However, if you’re looking for more, there are other sample letters of intent and statements of purpose for graduate school online. We’ve rounded up the best ones here, along with some strengths and weaknesses about each example.

Majortests Statement of Purpose Sample

This is a fairly straightforward, clearly written statement of purpose sample for a biology program. It includes useful commentary after each paragraph about what this statement of purpose is accomplishing.

• This statement of purpose sample is well-organized, with clear topic sentences and points made in each paragraph.
• The student clearly identifies what interests her about the program.
• The student proactively addresses questions about why she hasn’t gone directly to graduate school, and frames her professional research experience as a positive thing.
• She gives a tiny bit of color about her personality in a relevant way by discussing her involvement with the Natural History Society.
• In general, discussing high school interests is too far back in time unless the anecdote is very interesting or unusual. The detail about The Theory of Evolution is intriguing; the information about the high school teacher seems irrelevant. The student should have condensed this paragraph into a sentence or two.
• While this statement is cogently written and makes the candidate sound competent and well-qualified, it’s not exactly the most scintillating piece of writing out there. Some of the constructions are a little awkward or cliche. For example, the “many people have asked me” sentence followed by “the answer is” is a little bit clunky. This is probably fine for a STEM program. But just be aware that this statement is not a paragon of writing style.

UC Berkeley History Statement of Purpose Sample

This is a graduate school statement of purpose example from the UC Berkeley History department’s PhD program, with annotations from a professor as to why it’s a successful statement.

• The author is able to very clearly and articulately lay out her research interests and link them to past work she has successfully completed, namely, her thesis.
• She is able to identify several things about the program and Berkeley that indicate why it is a good fit for her research interests.
• She addresses the time she spent away from school and frames it as a positive, emphasizing that her use of time was well-considered and productive.
• Her writing is very vivid, with excellent word choice and great imagery.

While very well-written and engaging, this sample statement of purpose for graduate school is a little bit on the long side! It’s a little over two single-spaced pages, which is definitely pushing the limits of acceptable length. Try to keep yours at 2 pages or less. Some of the information on the thesis (which comprises over half of the statement of purpose) could be condensed to bring it down to two pages.

Pharmacy Residency Letter of Intent Sample

This is not technically a sample letter of intent for graduate school because it’s actually for a pharmacy residency program. However, this example still provides illumination as to what makes a decent graduate school letter of intent sample.

• This is a serviceable letter of intent: the writer clearly lays out their own goals within the field of pharmacy, what qualifications they have and how they’ve arrived at their interests, and how the program fits their needs.
• The writing is clearly structured and well-organized.
• The main weakness is that some of the writer’s statements come across as fairly generic. For example, “The PGY-1 Residency Program at UO Hospitals will provide me with the opportunity to further develop my clinical knowledge, critical thinking, teaching, research, and leadership skills” is a generic statement that could apply to any residency program. A punchier, more program-specific conclusion would have amped up this letter.
• While the writer does a decent job providing examples of their activities, like working as a tutor and attending the APhA conference, more specificity and detail in these examples would make the statement more memorable.
• There’s a typo in the last paragraph —a “to” that doesn’t belong! This is an unprofessional blip in an otherwise solid letter. Read you own letter of intent aloud to avoid this!

NIU Bad Statement of Purpose Example

This is an ineffective graduate school statement of purpose example, with annotations on why it doesn’t work.

As you might imagine, the main strength in this document is as an example of what not to do. Otherwise, there is little to recommend it.

• The annotations quite clearly detail the weaknesses of this statement. So I won’t address them exhaustively except to point out that this statement of purpose fails at both content and style. The author includes irrelevant anecdotes and lists without offering a decisive picture of interests or any particular insight into the field. Additionally, the statement is riddled with grammatical mistakes, awkward sentence structures, and strange acronyms.
• You’ll note that the commentary advises you to “never start with a quote.” I agree that you should never start with a freestanding quote as in this example. However, I do think starting with a quote is acceptable in cases like the Berkeley history example above, where the quote is brief and then directly linked to the research interest.

Graduate School Statement of Purpose Examples: 4 Key Points

Graduate programs ask for statement of purpose to hear about your interests and goals and why you think you and the program would be a good fit.

There are four key elements to a successful statement of purpose:

• A clear articulation of your goals and interests
• Evidence of past experiences and success
• Interest and fit with the program
• Strong writing

We’ve provided you with four successful statement of purpose samples from our graduate school experts!

A Practical Guide to Writing Quantitative and Qualitative Research Questions and Hypotheses in Scholarly Articles

The development of research questions and the subsequent hypotheses are prerequisites to defining the main research purpose and specific objectives of a study. Consequently, these objectives determine the study design and research outcome. The development of research questions is a process based on knowledge of current trends, cutting-edge studies, and technological advances in the research field. Excellent research questions are focused and require a comprehensive literature search and in-depth understanding of the problem being investigated. Initially, research questions may be written as descriptive questions which could be developed into inferential questions. These questions must be specific and concise to provide a clear foundation for developing hypotheses. Hypotheses are more formal predictions about the research outcomes. These specify the possible results that may or may not be expected regarding the relationship between groups. Thus, research questions and hypotheses clarify the main purpose and specific objectives of the study, which in turn dictate the design of the study, its direction, and outcome. Studies developed from good research questions and hypotheses will have trustworthy outcomes with wide-ranging social and health implications.

INTRODUCTION

Scientific research is usually initiated by posing evidenced-based research questions which are then explicitly restated as hypotheses. 1 , 2 The hypotheses provide directions to guide the study, solutions, explanations, and expected results. 3 , 4 Both research questions and hypotheses are essentially formulated based on conventional theories and real-world processes, which allow the inception of novel studies and the ethical testing of ideas. 5 , 6

It is crucial to have knowledge of both quantitative and qualitative research 2 as both types of research involve writing research questions and hypotheses. 7 However, these crucial elements of research are sometimes overlooked; if not overlooked, then framed without the forethought and meticulous attention it needs. Planning and careful consideration are needed when developing quantitative or qualitative research, particularly when conceptualizing research questions and hypotheses. 4

There is a continuing need to support researchers in the creation of innovative research questions and hypotheses, as well as for journal articles that carefully review these elements. 1 When research questions and hypotheses are not carefully thought of, unethical studies and poor outcomes usually ensue. Carefully formulated research questions and hypotheses define well-founded objectives, which in turn determine the appropriate design, course, and outcome of the study. This article then aims to discuss in detail the various aspects of crafting research questions and hypotheses, with the goal of guiding researchers as they develop their own. Examples from the authors and peer-reviewed scientific articles in the healthcare field are provided to illustrate key points.

DEFINITIONS AND RELATIONSHIP OF RESEARCH QUESTIONS AND HYPOTHESES

A research question is what a study aims to answer after data analysis and interpretation. The answer is written in length in the discussion section of the paper. Thus, the research question gives a preview of the different parts and variables of the study meant to address the problem posed in the research question. 1 An excellent research question clarifies the research writing while facilitating understanding of the research topic, objective, scope, and limitations of the study. 5

On the other hand, a research hypothesis is an educated statement of an expected outcome. This statement is based on background research and current knowledge. 8 , 9 The research hypothesis makes a specific prediction about a new phenomenon 10 or a formal statement on the expected relationship between an independent variable and a dependent variable. 3 , 11 It provides a tentative answer to the research question to be tested or explored. 4

Hypotheses employ reasoning to predict a theory-based outcome. 10 These can also be developed from theories by focusing on components of theories that have not yet been observed. 10 The validity of hypotheses is often based on the testability of the prediction made in a reproducible experiment. 8

Conversely, hypotheses can also be rephrased as research questions. Several hypotheses based on existing theories and knowledge may be needed to answer a research question. Developing ethical research questions and hypotheses creates a research design that has logical relationships among variables. These relationships serve as a solid foundation for the conduct of the study. 4 , 11 Haphazardly constructed research questions can result in poorly formulated hypotheses and improper study designs, leading to unreliable results. Thus, the formulations of relevant research questions and verifiable hypotheses are crucial when beginning research. 12

CHARACTERISTICS OF GOOD RESEARCH QUESTIONS AND HYPOTHESES

Excellent research questions are specific and focused. These integrate collective data and observations to confirm or refute the subsequent hypotheses. Well-constructed hypotheses are based on previous reports and verify the research context. These are realistic, in-depth, sufficiently complex, and reproducible. More importantly, these hypotheses can be addressed and tested. 13

There are several characteristics of well-developed hypotheses. Good hypotheses are 1) empirically testable 7 , 10 , 11 , 13 ; 2) backed by preliminary evidence 9 ; 3) testable by ethical research 7 , 9 ; 4) based on original ideas 9 ; 5) have evidenced-based logical reasoning 10 ; and 6) can be predicted. 11 Good hypotheses can infer ethical and positive implications, indicating the presence of a relationship or effect relevant to the research theme. 7 , 11 These are initially developed from a general theory and branch into specific hypotheses by deductive reasoning. In the absence of a theory to base the hypotheses, inductive reasoning based on specific observations or findings form more general hypotheses. 10

TYPES OF RESEARCH QUESTIONS AND HYPOTHESES

Research questions and hypotheses are developed according to the type of research, which can be broadly classified into quantitative and qualitative research. We provide a summary of the types of research questions and hypotheses under quantitative and qualitative research categories in Table 1 .

Research questions in quantitative research

In quantitative research, research questions inquire about the relationships among variables being investigated and are usually framed at the start of the study. These are precise and typically linked to the subject population, dependent and independent variables, and research design. 1 Research questions may also attempt to describe the behavior of a population in relation to one or more variables, or describe the characteristics of variables to be measured ( descriptive research questions ). 1 , 5 , 14 These questions may also aim to discover differences between groups within the context of an outcome variable ( comparative research questions ), 1 , 5 , 14 or elucidate trends and interactions among variables ( relationship research questions ). 1 , 5 We provide examples of descriptive, comparative, and relationship research questions in quantitative research in Table 2 .

Hypotheses in quantitative research

In quantitative research, hypotheses predict the expected relationships among variables. 15 Relationships among variables that can be predicted include 1) between a single dependent variable and a single independent variable ( simple hypothesis ) or 2) between two or more independent and dependent variables ( complex hypothesis ). 4 , 11 Hypotheses may also specify the expected direction to be followed and imply an intellectual commitment to a particular outcome ( directional hypothesis ) 4 . On the other hand, hypotheses may not predict the exact direction and are used in the absence of a theory, or when findings contradict previous studies ( non-directional hypothesis ). 4 In addition, hypotheses can 1) define interdependency between variables ( associative hypothesis ), 4 2) propose an effect on the dependent variable from manipulation of the independent variable ( causal hypothesis ), 4 3) state a negative relationship between two variables ( null hypothesis ), 4 , 11 , 15 4) replace the working hypothesis if rejected ( alternative hypothesis ), 15 explain the relationship of phenomena to possibly generate a theory ( working hypothesis ), 11 5) involve quantifiable variables that can be tested statistically ( statistical hypothesis ), 11 6) or express a relationship whose interlinks can be verified logically ( logical hypothesis ). 11 We provide examples of simple, complex, directional, non-directional, associative, causal, null, alternative, working, statistical, and logical hypotheses in quantitative research, as well as the definition of quantitative hypothesis-testing research in Table 3 .

Research questions in qualitative research

Unlike research questions in quantitative research, research questions in qualitative research are usually continuously reviewed and reformulated. The central question and associated subquestions are stated more than the hypotheses. 15 The central question broadly explores a complex set of factors surrounding the central phenomenon, aiming to present the varied perspectives of participants. 15

There are varied goals for which qualitative research questions are developed. These questions can function in several ways, such as to 1) identify and describe existing conditions ( contextual research question s); 2) describe a phenomenon ( descriptive research questions ); 3) assess the effectiveness of existing methods, protocols, theories, or procedures ( evaluation research questions ); 4) examine a phenomenon or analyze the reasons or relationships between subjects or phenomena ( explanatory research questions ); or 5) focus on unknown aspects of a particular topic ( exploratory research questions ). 5 In addition, some qualitative research questions provide new ideas for the development of theories and actions ( generative research questions ) or advance specific ideologies of a position ( ideological research questions ). 1 Other qualitative research questions may build on a body of existing literature and become working guidelines ( ethnographic research questions ). Research questions may also be broadly stated without specific reference to the existing literature or a typology of questions ( phenomenological research questions ), may be directed towards generating a theory of some process ( grounded theory questions ), or may address a description of the case and the emerging themes ( qualitative case study questions ). 15 We provide examples of contextual, descriptive, evaluation, explanatory, exploratory, generative, ideological, ethnographic, phenomenological, grounded theory, and qualitative case study research questions in qualitative research in Table 4 , and the definition of qualitative hypothesis-generating research in Table 5 .

Qualitative studies usually pose at least one central research question and several subquestions starting with How or What . These research questions use exploratory verbs such as explore or describe . These also focus on one central phenomenon of interest, and may mention the participants and research site. 15

Hypotheses in qualitative research

Hypotheses in qualitative research are stated in the form of a clear statement concerning the problem to be investigated. Unlike in quantitative research where hypotheses are usually developed to be tested, qualitative research can lead to both hypothesis-testing and hypothesis-generating outcomes. 2 When studies require both quantitative and qualitative research questions, this suggests an integrative process between both research methods wherein a single mixed-methods research question can be developed. 1

FRAMEWORKS FOR DEVELOPING RESEARCH QUESTIONS AND HYPOTHESES

Research questions followed by hypotheses should be developed before the start of the study. 1 , 12 , 14 It is crucial to develop feasible research questions on a topic that is interesting to both the researcher and the scientific community. This can be achieved by a meticulous review of previous and current studies to establish a novel topic. Specific areas are subsequently focused on to generate ethical research questions. The relevance of the research questions is evaluated in terms of clarity of the resulting data, specificity of the methodology, objectivity of the outcome, depth of the research, and impact of the study. 1 , 5 These aspects constitute the FINER criteria (i.e., Feasible, Interesting, Novel, Ethical, and Relevant). 1 Clarity and effectiveness are achieved if research questions meet the FINER criteria. In addition to the FINER criteria, Ratan et al. described focus, complexity, novelty, feasibility, and measurability for evaluating the effectiveness of research questions. 14

The PICOT and PEO frameworks are also used when developing research questions. 1 The following elements are addressed in these frameworks, PICOT: P-population/patients/problem, I-intervention or indicator being studied, C-comparison group, O-outcome of interest, and T-timeframe of the study; PEO: P-population being studied, E-exposure to preexisting conditions, and O-outcome of interest. 1 Research questions are also considered good if these meet the “FINERMAPS” framework: Feasible, Interesting, Novel, Ethical, Relevant, Manageable, Appropriate, Potential value/publishable, and Systematic. 14

As we indicated earlier, research questions and hypotheses that are not carefully formulated result in unethical studies or poor outcomes. To illustrate this, we provide some examples of ambiguous research question and hypotheses that result in unclear and weak research objectives in quantitative research ( Table 6 ) 16 and qualitative research ( Table 7 ) 17 , and how to transform these ambiguous research question(s) and hypothesis(es) into clear and good statements.

CONSTRUCTING RESEARCH QUESTIONS AND HYPOTHESES

To construct effective research questions and hypotheses, it is very important to 1) clarify the background and 2) identify the research problem at the outset of the research, within a specific timeframe. 9 Then, 3) review or conduct preliminary research to collect all available knowledge about the possible research questions by studying theories and previous studies. 18 Afterwards, 4) construct research questions to investigate the research problem. Identify variables to be accessed from the research questions 4 and make operational definitions of constructs from the research problem and questions. Thereafter, 5) construct specific deductive or inductive predictions in the form of hypotheses. 4 Finally, 6) state the study aims . This general flow for constructing effective research questions and hypotheses prior to conducting research is shown in Fig. 1 .

Research questions are used more frequently in qualitative research than objectives or hypotheses. 3 These questions seek to discover, understand, explore or describe experiences by asking “What” or “How.” The questions are open-ended to elicit a description rather than to relate variables or compare groups. The questions are continually reviewed, reformulated, and changed during the qualitative study. 3 Research questions are also used more frequently in survey projects than hypotheses in experiments in quantitative research to compare variables and their relationships.

Hypotheses are constructed based on the variables identified and as an if-then statement, following the template, ‘If a specific action is taken, then a certain outcome is expected.’ At this stage, some ideas regarding expectations from the research to be conducted must be drawn. 18 Then, the variables to be manipulated (independent) and influenced (dependent) are defined. 4 Thereafter, the hypothesis is stated and refined, and reproducible data tailored to the hypothesis are identified, collected, and analyzed. 4 The hypotheses must be testable and specific, 18 and should describe the variables and their relationships, the specific group being studied, and the predicted research outcome. 18 Hypotheses construction involves a testable proposition to be deduced from theory, and independent and dependent variables to be separated and measured separately. 3 Therefore, good hypotheses must be based on good research questions constructed at the start of a study or trial. 12

In summary, research questions are constructed after establishing the background of the study. Hypotheses are then developed based on the research questions. Thus, it is crucial to have excellent research questions to generate superior hypotheses. In turn, these would determine the research objectives and the design of the study, and ultimately, the outcome of the research. 12 Algorithms for building research questions and hypotheses are shown in Fig. 2 for quantitative research and in Fig. 3 for qualitative research.

EXAMPLES OF RESEARCH QUESTIONS FROM PUBLISHED ARTICLES

• EXAMPLE 1. Descriptive research question (quantitative research)
• - Presents research variables to be assessed (distinct phenotypes and subphenotypes)
• “BACKGROUND: Since COVID-19 was identified, its clinical and biological heterogeneity has been recognized. Identifying COVID-19 phenotypes might help guide basic, clinical, and translational research efforts.
• RESEARCH QUESTION: Does the clinical spectrum of patients with COVID-19 contain distinct phenotypes and subphenotypes? ” 19
• EXAMPLE 2. Relationship research question (quantitative research)
• - Shows interactions between dependent variable (static postural control) and independent variable (peripheral visual field loss)
• “Background: Integration of visual, vestibular, and proprioceptive sensations contributes to postural control. People with peripheral visual field loss have serious postural instability. However, the directional specificity of postural stability and sensory reweighting caused by gradual peripheral visual field loss remain unclear.
• Research question: What are the effects of peripheral visual field loss on static postural control ?” 20
• EXAMPLE 3. Comparative research question (quantitative research)
• - Clarifies the difference among groups with an outcome variable (patients enrolled in COMPERA with moderate PH or severe PH in COPD) and another group without the outcome variable (patients with idiopathic pulmonary arterial hypertension (IPAH))
• “BACKGROUND: Pulmonary hypertension (PH) in COPD is a poorly investigated clinical condition.
• RESEARCH QUESTION: Which factors determine the outcome of PH in COPD?
• STUDY DESIGN AND METHODS: We analyzed the characteristics and outcome of patients enrolled in the Comparative, Prospective Registry of Newly Initiated Therapies for Pulmonary Hypertension (COMPERA) with moderate or severe PH in COPD as defined during the 6th PH World Symposium who received medical therapy for PH and compared them with patients with idiopathic pulmonary arterial hypertension (IPAH) .” 21
• EXAMPLE 4. Exploratory research question (qualitative research)
• - Explores areas that have not been fully investigated (perspectives of families and children who receive care in clinic-based child obesity treatment) to have a deeper understanding of the research problem
• “Problem: Interventions for children with obesity lead to only modest improvements in BMI and long-term outcomes, and data are limited on the perspectives of families of children with obesity in clinic-based treatment. This scoping review seeks to answer the question: What is known about the perspectives of families and children who receive care in clinic-based child obesity treatment? This review aims to explore the scope of perspectives reported by families of children with obesity who have received individualized outpatient clinic-based obesity treatment.” 22
• EXAMPLE 5. Relationship research question (quantitative research)
• - Defines interactions between dependent variable (use of ankle strategies) and independent variable (changes in muscle tone)
• “Background: To maintain an upright standing posture against external disturbances, the human body mainly employs two types of postural control strategies: “ankle strategy” and “hip strategy.” While it has been reported that the magnitude of the disturbance alters the use of postural control strategies, it has not been elucidated how the level of muscle tone, one of the crucial parameters of bodily function, determines the use of each strategy. We have previously confirmed using forward dynamics simulations of human musculoskeletal models that an increased muscle tone promotes the use of ankle strategies. The objective of the present study was to experimentally evaluate a hypothesis: an increased muscle tone promotes the use of ankle strategies. Research question: Do changes in the muscle tone affect the use of ankle strategies ?” 23

EXAMPLES OF HYPOTHESES IN PUBLISHED ARTICLES

• EXAMPLE 1. Working hypothesis (quantitative research)
• - A hypothesis that is initially accepted for further research to produce a feasible theory
• “As fever may have benefit in shortening the duration of viral illness, it is plausible to hypothesize that the antipyretic efficacy of ibuprofen may be hindering the benefits of a fever response when taken during the early stages of COVID-19 illness .” 24
• “In conclusion, it is plausible to hypothesize that the antipyretic efficacy of ibuprofen may be hindering the benefits of a fever response . The difference in perceived safety of these agents in COVID-19 illness could be related to the more potent efficacy to reduce fever with ibuprofen compared to acetaminophen. Compelling data on the benefit of fever warrant further research and review to determine when to treat or withhold ibuprofen for early stage fever for COVID-19 and other related viral illnesses .” 24
• EXAMPLE 2. Exploratory hypothesis (qualitative research)
• - Explores particular areas deeper to clarify subjective experience and develop a formal hypothesis potentially testable in a future quantitative approach
• “We hypothesized that when thinking about a past experience of help-seeking, a self distancing prompt would cause increased help-seeking intentions and more favorable help-seeking outcome expectations .” 25
• “Conclusion
• Although a priori hypotheses were not supported, further research is warranted as results indicate the potential for using self-distancing approaches to increasing help-seeking among some people with depressive symptomatology.” 25
• EXAMPLE 3. Hypothesis-generating research to establish a framework for hypothesis testing (qualitative research)
• “We hypothesize that compassionate care is beneficial for patients (better outcomes), healthcare systems and payers (lower costs), and healthcare providers (lower burnout). ” 26
• Compassionomics is the branch of knowledge and scientific study of the effects of compassionate healthcare. Our main hypotheses are that compassionate healthcare is beneficial for (1) patients, by improving clinical outcomes, (2) healthcare systems and payers, by supporting financial sustainability, and (3) HCPs, by lowering burnout and promoting resilience and well-being. The purpose of this paper is to establish a scientific framework for testing the hypotheses above . If these hypotheses are confirmed through rigorous research, compassionomics will belong in the science of evidence-based medicine, with major implications for all healthcare domains.” 26
• EXAMPLE 4. Statistical hypothesis (quantitative research)
• - An assumption is made about the relationship among several population characteristics ( gender differences in sociodemographic and clinical characteristics of adults with ADHD ). Validity is tested by statistical experiment or analysis ( chi-square test, Students t-test, and logistic regression analysis)
• “Our research investigated gender differences in sociodemographic and clinical characteristics of adults with ADHD in a Japanese clinical sample. Due to unique Japanese cultural ideals and expectations of women's behavior that are in opposition to ADHD symptoms, we hypothesized that women with ADHD experience more difficulties and present more dysfunctions than men . We tested the following hypotheses: first, women with ADHD have more comorbidities than men with ADHD; second, women with ADHD experience more social hardships than men, such as having less full-time employment and being more likely to be divorced.” 27
• “Statistical Analysis
• ( text omitted ) Between-gender comparisons were made using the chi-squared test for categorical variables and Students t-test for continuous variables…( text omitted ). A logistic regression analysis was performed for employment status, marital status, and comorbidity to evaluate the independent effects of gender on these dependent variables.” 27

EXAMPLES OF HYPOTHESIS AS WRITTEN IN PUBLISHED ARTICLES IN RELATION TO OTHER PARTS

• EXAMPLE 1. Background, hypotheses, and aims are provided
• “Pregnant women need skilled care during pregnancy and childbirth, but that skilled care is often delayed in some countries …( text omitted ). The focused antenatal care (FANC) model of WHO recommends that nurses provide information or counseling to all pregnant women …( text omitted ). Job aids are visual support materials that provide the right kind of information using graphics and words in a simple and yet effective manner. When nurses are not highly trained or have many work details to attend to, these job aids can serve as a content reminder for the nurses and can be used for educating their patients (Jennings, Yebadokpo, Affo, & Agbogbe, 2010) ( text omitted ). Importantly, additional evidence is needed to confirm how job aids can further improve the quality of ANC counseling by health workers in maternal care …( text omitted )” 28
• “ This has led us to hypothesize that the quality of ANC counseling would be better if supported by job aids. Consequently, a better quality of ANC counseling is expected to produce higher levels of awareness concerning the danger signs of pregnancy and a more favorable impression of the caring behavior of nurses .” 28
• “This study aimed to examine the differences in the responses of pregnant women to a job aid-supported intervention during ANC visit in terms of 1) their understanding of the danger signs of pregnancy and 2) their impression of the caring behaviors of nurses to pregnant women in rural Tanzania.” 28
• EXAMPLE 2. Background, hypotheses, and aims are provided
• “We conducted a two-arm randomized controlled trial (RCT) to evaluate and compare changes in salivary cortisol and oxytocin levels of first-time pregnant women between experimental and control groups. The women in the experimental group touched and held an infant for 30 min (experimental intervention protocol), whereas those in the control group watched a DVD movie of an infant (control intervention protocol). The primary outcome was salivary cortisol level and the secondary outcome was salivary oxytocin level.” 29
• “ We hypothesize that at 30 min after touching and holding an infant, the salivary cortisol level will significantly decrease and the salivary oxytocin level will increase in the experimental group compared with the control group .” 29
• EXAMPLE 3. Background, aim, and hypothesis are provided
• “In countries where the maternal mortality ratio remains high, antenatal education to increase Birth Preparedness and Complication Readiness (BPCR) is considered one of the top priorities [1]. BPCR includes birth plans during the antenatal period, such as the birthplace, birth attendant, transportation, health facility for complications, expenses, and birth materials, as well as family coordination to achieve such birth plans. In Tanzania, although increasing, only about half of all pregnant women attend an antenatal clinic more than four times [4]. Moreover, the information provided during antenatal care (ANC) is insufficient. In the resource-poor settings, antenatal group education is a potential approach because of the limited time for individual counseling at antenatal clinics.” 30
• “This study aimed to evaluate an antenatal group education program among pregnant women and their families with respect to birth-preparedness and maternal and infant outcomes in rural villages of Tanzania.” 30
• “ The study hypothesis was if Tanzanian pregnant women and their families received a family-oriented antenatal group education, they would (1) have a higher level of BPCR, (2) attend antenatal clinic four or more times, (3) give birth in a health facility, (4) have less complications of women at birth, and (5) have less complications and deaths of infants than those who did not receive the education .” 30

Research questions and hypotheses are crucial components to any type of research, whether quantitative or qualitative. These questions should be developed at the very beginning of the study. Excellent research questions lead to superior hypotheses, which, like a compass, set the direction of research, and can often determine the successful conduct of the study. Many research studies have floundered because the development of research questions and subsequent hypotheses was not given the thought and meticulous attention needed. The development of research questions and hypotheses is an iterative process based on extensive knowledge of the literature and insightful grasp of the knowledge gap. Focused, concise, and specific research questions provide a strong foundation for constructing hypotheses which serve as formal predictions about the research outcomes. Research questions and hypotheses are crucial elements of research that should not be overlooked. They should be carefully thought of and constructed when planning research. This avoids unethical studies and poor outcomes by defining well-founded objectives that determine the design, course, and outcome of the study.

Infection Control Basics

• Infection control prevents or stops the spread of infections in healthcare settings.
• Healthcare workers can reduce the risk of healthcare-associated infections and protect themselves, patients and visitors by following CDC guidelines.

Germs are a part of everyday life. Germs live in our air, soil, water and in and on our bodies. Some germs are helpful, others are harmful.

An infection occurs when germs enter the body, increase in number and the body reacts. Only a small portion of germs can cause infection.

Terms to know

• Sources : places where infectious agents (germs) live (e.g., sinks, surfaces, human skin). Sources are also called reservoirs.
• Susceptible person: someone who is not vaccinated or otherwise immune. For example, a person with a weakened immune system who has a way for the germs to enter the body.
• Transmission: a way germs move to the susceptible person. Germs depend on people, the environment and/or medical equipment to move in healthcare settings. Transmission is also called a pathway.
• Colonization: when someone has germs on or in their body but does not have symptoms of an infection. Colonized people can still transmit the germs they carry.

For an infection to occur, germs must transmit to a person from a source, enter their body, invade tissues, multiply and cause a reaction.

How it works in healthcare settings

Sources can be:.

• People such as patients, healthcare workers and visitors.
• Dry surfaces in patient care areas such as bed rails, medical equipment, countertops and tables).
• Wet surfaces, moist environments and biofilms (collections of microorganisms that stick to each other and surfaces in moist environments, like the insides of pipes).
• Cooling towers, faucets and sinks, and equipment such as ventilators.
• Indwelling medical devices such as catheters and IV lines.
• Dust or decaying debris such as construction dust or wet materials from water leaks.

Transmission can happen through activities such as:

• Physical contact, like when a healthcare provider touches medical equipment that has germs on it and then touches a patient before cleaning their hands.
• Sprays and splashes when an infected person coughs or sneezes. This creates droplets containing the germs, and the droplets land on a person's eyes, nose or mouth.
• Inhalation when infected patients cough or talk, or construction zones kick up dirt and dust containing germs, which another person breathes in.
• Sharps injuries such as when someone is accidentally stuck with a used needle.

A person can become more susceptible to infection when:

• They have underlying medical conditions such as diabetes, cancer or organ transplantation. These can decrease the immune system's ability to fight infection.
• They take medications such as antibiotics, steroids and certain cancer fighting medications. These can decrease the body's ability to fight infection.
• They receive treatments or procedures such as urinary catheters, tubes and surgery, which can provide additional ways for germs to enter the body.

Recommendations

Healthcare providers.

Healthcare providers can perform basic infection prevention measures to prevent infection.

There are 2 tiers of recommended precautions to prevent the spread of infections in healthcare settings:

• Standard Precautions , used for all patient care.
• Transmission-based Precautions , used for patients who may be infected or colonized with certain germs.

There are also transmission- and germ-specific guidelines providers can follow to prevent transmission and healthcare-associated infections from happening.

Purpose statement overview.

The purpose statement succinctly explains (on no more than 1 page) the objectives of the research study. These objectives must directly address the problem and help close the stated gap. Expressed as a formula:

Good purpose statements:

• Flow from the problem statement and actually address the proposed problem
• Are concise and clear
• Answer the question ‘Why are you doing this research?’
• Match the methodology (similar to research questions)
• Have a ‘hook’ to get the reader’s attention
• Set the stage by clearly stating, “The purpose of this (qualitative or quantitative) study is to ...

In PhD studies, the purpose usually involves applying a theory to solve the problem. In other words, the purpose tells the reader what the goal of the study is, and what your study will accomplish, through which theoretical lens. The purpose statement also includes brief information about direction, scope, and where the data will come from.

A problem and gap in combination can lead to different research objectives, and hence, different purpose statements. In the example from above where the problem was severe underrepresentation of female CEOs in Fortune 500 companies and the identified gap related to lack of research of male-dominated boards; one purpose might be to explore implicit biases in male-dominated boards through the lens of feminist theory. Another purpose may be to determine how board members rated female and male candidates on scales of competency, professionalism, and experience to predict which candidate will be selected for the CEO position. The first purpose may involve a qualitative ethnographic study in which the researcher observes board meetings and hiring interviews; the second may involve a quantitative regression analysis. The outcomes will be very different, so it’s important that you find out exactly how you want to address a problem and help close a gap!

The purpose of the study must not only align with the problem and address a gap; it must also align with the chosen research method. In fact, the DP/DM template requires you to name the  research method at the very beginning of the purpose statement. The research verb must match the chosen method. In general, quantitative studies involve “closed-ended” research verbs such as determine , measure , correlate , explain , compare , validate , identify , or examine ; whereas qualitative studies involve “open-ended” research verbs such as explore , understand , narrate , articulate [meanings], discover , or develop .

A qualitative purpose statement following the color-coded problem statement (assumed here to be low well-being among financial sector employees) + gap (lack of research on followers of mid-level managers), might start like this:

In response to declining levels of employee well-being, the purpose of the qualitative phenomenology was to explore and understand the lived experiences related to the well-being of the followers of novice mid-level managers in the financial services industry. The levels of follower well-being have been shown to correlate to employee morale, turnover intention, and customer orientation (Eren et al., 2013). A combined framework of Leader-Member Exchange (LMX) Theory and the employee well-being concept informed the research questions and supported the inquiry, analysis, and interpretation of the experiences of followers of novice managers in the financial services industry.

A quantitative purpose statement for the same problem and gap might start like this:

In response to declining levels of employee well-being, the purpose of the quantitative correlational study was to determine which leadership factors predict employee well-being of the followers of novice mid-level managers in the financial services industry. Leadership factors were measured by the Leader-Member Exchange (LMX) assessment framework  by Mantlekow (2015), and employee well-being was conceptualized as a compound variable consisting of self-reported turnover-intent and psychological test scores from the Mental Health Survey (MHS) developed by Johns Hopkins University researchers.

Both of these purpose statements reflect viable research strategies and both align with the problem and gap so it’s up to the researcher to design a study in a manner that reflects personal preferences and desired study outcomes. Note that the quantitative research purpose incorporates operationalized concepts  or variables ; that reflect the way the researcher intends to measure the key concepts under study; whereas the qualitative purpose statement isn’t about translating the concepts under study as variables but instead aim to explore and understand the core research phenomenon.  

Best Practices for Writing your Purpose Statement

Always keep in mind that the dissertation process is iterative, and your writing, over time, will be refined as clarity is gradually achieved. Most of the time, greater clarity for the purpose statement and other components of the Dissertation is the result of a growing understanding of the literature in the field. As you increasingly master the literature you will also increasingly clarify the purpose of your study.

The purpose statement should flow directly from the problem statement. There should be clear and obvious alignment between the two and that alignment will get tighter and more pronounced as your work progresses.

The purpose statement should specifically address the reason for conducting the study, with emphasis on the word specifically. There should not be any doubt in your readers’ minds as to the purpose of your study. To achieve this level of clarity you will need to also insure there is no doubt in your mind as to the purpose of your study.

Many researchers benefit from stopping your work during the research process when insight strikes you and write about it while it is still fresh in your mind. This can help you clarify all aspects of a dissertation, including clarifying its purpose.

Your Chair and your committee members can help you to clarify your study’s purpose so carefully attend to any feedback they offer.

The purpose statement should reflect the research questions and vice versa. The chain of alignment that began with the research problem description and continues on to the research purpose, research questions, and methodology must be respected at all times during dissertation development. You are to succinctly describe the overarching goal of the study that reflects the research questions. Each research question narrows and focuses the purpose statement. Conversely, the purpose statement encompasses all of the research questions.

Identify in the purpose statement the research method as quantitative, qualitative or mixed (i.e., “The purpose of this [qualitative/quantitative/mixed] study is to ...)

Avoid the use of the phrase “research study” since the two words together are redundant.

Follow the initial declaration of purpose with a brief overview of how, with what instruments/data, with whom and where (as applicable) the study will be conducted. Identify variables/constructs and/or phenomenon/concept/idea. Since this section is to be a concise paragraph, emphasis must be placed on the word brief. However, adding these details will give your readers a very clear picture of the purpose of your research.

Developing the purpose section of your dissertation is usually not achieved in a single flash of insight. The process involves a great deal of reading to find out what other scholars have done to address the research topic and problem you have identified. The purpose section of your dissertation could well be the most important paragraph you write during your academic career, and every word should be carefully selected. Think of it as the DNA of your dissertation. Everything else you write should emerge directly and clearly from your purpose statement. In turn, your purpose statement should emerge directly and clearly from your research problem description. It is good practice to print out your problem statement and purpose statement and keep them in front of you as you work on each part of your dissertation in order to insure alignment.

It is helpful to collect several dissertations similar to the one you envision creating. Extract the problem descriptions and purpose statements of other dissertation authors and compare them in order to sharpen your thinking about your own work.  Comparing how other dissertation authors have handled the many challenges you are facing can be an invaluable exercise. Keep in mind that individual universities use their own tailored protocols for presenting key components of the dissertation so your review of these purpose statements should focus on content rather than form.

Once your purpose statement is set it must be consistently presented throughout the dissertation. This may require some recursive editing because the way you articulate your purpose may evolve as you work on various aspects of your dissertation. Whenever you make an adjustment to your purpose statement you should carefully follow up on the editing and conceptual ramifications throughout the entire document.

In establishing your purpose you should NOT advocate for a particular outcome. Research should be done to answer questions not prove a point. As a researcher, you are to inquire with an open mind, and even when you come to the work with clear assumptions, your job is to prove the validity of the conclusions reached. For example, you would not say the purpose of your research project is to demonstrate that there is a relationship between two variables. Such a statement presupposes you know the answer before your research is conducted and promotes or supports (advocates on behalf of) a particular outcome. A more appropriate purpose statement would be to examine or explore the relationship between two variables.

Your purpose statement should not imply that you are going to prove something. You may be surprised to learn that we cannot prove anything in scholarly research for two reasons. First, in quantitative analyses, statistical tests calculate the probability that something is true rather than establishing it as true. Second, in qualitative research, the study can only purport to describe what is occurring from the perspective of the participants. Whether or not the phenomenon they are describing is true in a larger context is not knowable. We cannot observe the phenomenon in all settings and in all circumstances.

Writing your Purpose Statement

It is important to distinguish in your mind the differences between the Problem Statement and Purpose Statement.

The Problem Statement is why I am doing the research

The Purpose Statement is what type of research I am doing to fit or address the problem

The Purpose Statement includes:

• Method of Study
• Specific Population

Remember, as you are contemplating what to include in your purpose statement and then when you are writing it, the purpose statement is a concise paragraph that describes the intent of the study, and it should flow directly from the problem statement.  It should specifically address the reason for conducting the study, and reflect the research questions.  Further, it should identify the research method as qualitative, quantitative, or mixed.  Then provide a brief overview of how the study will be conducted, with what instruments/data collection methods, and with whom (subjects) and where (as applicable). Finally, you should identify variables/constructs and/or phenomenon/concept/idea.

Qualitative Purpose Statement

Creswell (2002) suggested for writing purpose statements in qualitative research include using deliberate phrasing to alert the reader to the purpose statement. Verbs that indicate what will take place in the research and the use of non-directional language that do not suggest an outcome are key. A purpose statement should focus on a single idea or concept, with a broad definition of the idea or concept. How the concept was investigated should also be included, as well as participants in the study and locations for the research to give the reader a sense of with whom and where the study took place. 

Creswell (2003) advised the following script for purpose statements in qualitative research:

“The purpose of this qualitative_________________ (strategy of inquiry, such as ethnography, case study, or other type) study is (was? will be?) to ________________ (understand? describe? develop? discover?) the _________________(central phenomenon being studied) for ______________ (the participants, such as the individual, groups, organization) at __________(research site). At this stage in the research, the __________ (central phenomenon being studied) will be generally defined as ___________________ (provide a general definition)” (pg. 90).

Quantitative Purpose Statement

Creswell (2003) offers vast differences between the purpose statements written for qualitative research and those written for quantitative research, particularly with respect to language and the inclusion of variables. The comparison of variables is often a focus of quantitative research, with the variables distinguishable by either the temporal order or how they are measured. As with qualitative research purpose statements, Creswell (2003) recommends the use of deliberate language to alert the reader to the purpose of the study, but quantitative purpose statements also include the theory or conceptual framework guiding the study and the variables that are being studied and how they are related. 

Creswell (2003) suggests the following script for drafting purpose statements in quantitative research:

“The purpose of this _____________________ (experiment? survey?) study is (was? will be?) to test the theory of _________________that _________________ (compares? relates?) the ___________(independent variable) to _________________________(dependent variable), controlling for _______________________ (control variables) for ___________________ (participants) at _________________________ (the research site). The independent variable(s) _____________________ will be generally defined as _______________________ (provide a general definition). The dependent variable(s) will be generally defined as _____________________ (provide a general definition), and the control and intervening variables(s), _________________ (identify the control and intervening variables) will be statistically controlled in this study” (pg. 97).

Sample Purpose Statements

• The purpose of this qualitative study was to determine how participation in service-learning in an alternative school impacted students academically, civically, and personally.  There is ample evidence demonstrating the failure of schools for students at-risk; however, there is still a need to demonstrate why these students are successful in non-traditional educational programs like the service-learning model used at TDS.  This study was unique in that it examined one alternative school’s approach to service-learning in a setting where students not only serve, but faculty serve as volunteer teachers.  The use of a constructivist approach in service-learning in an alternative school setting was examined in an effort to determine whether service-learning participation contributes positively to academic, personal, and civic gain for students, and to examine student and teacher views regarding the overall outcomes of service-learning.  This study was completed using an ethnographic approach that included observations, content analysis, and interviews with teachers at The David School.
• The purpose of this quantitative non-experimental cross-sectional linear multiple regression design was to investigate the relationship among early childhood teachers’ self-reported assessment of multicultural awareness as measured by responses from the Teacher Multicultural Attitude Survey (TMAS) and supervisors’ observed assessment of teachers’ multicultural competency skills as measured by the Multicultural Teaching Competency Scale (MTCS) survey. Demographic data such as number of multicultural training hours, years teaching in Dubai, curriculum program at current school, and age were also examined and their relationship to multicultural teaching competency. The study took place in the emirate of Dubai where there were 14,333 expatriate teachers employed in private schools (KHDA, 2013b).
• The purpose of this quantitative, non-experimental study is to examine the degree to which stages of change, gender, acculturation level and trauma types predicts the reluctance of Arab refugees, aged 18 and over, in the Dearborn, MI area, to seek professional help for their mental health needs. This study will utilize four instruments to measure these variables: University of Rhode Island Change Assessment (URICA: DiClemente & Hughes, 1990); Cumulative Trauma Scale (Kira, 2012); Acculturation Rating Scale for Arabic Americans-II Arabic and English (ARSAA-IIA, ARSAA-IIE: Jadalla & Lee, 2013), and a demographic survey. This study will examine 1) the relationship between stages of change, gender, acculturation levels, and trauma types and Arab refugees’ help-seeking behavior, 2) the degree to which any of these variables can predict Arab refugee help-seeking behavior.  Additionally, the outcome of this study could provide researchers and clinicians with a stage-based model, TTM, for measuring Arab refugees’ help-seeking behavior and lay a foundation for how TTM can help target the clinical needs of Arab refugees. Lastly, this attempt to apply the TTM model to Arab refugees’ condition could lay the foundation for future research to investigate the application of TTM to clinical work among refugee populations.
• The purpose of this qualitative, phenomenological study is to describe the lived experiences of LLM for 10 EFL learners in rural Guatemala and to utilize that data to determine how it conforms to, or possibly challenges, current theoretical conceptions of LLM. In accordance with Morse’s (1994) suggestion that a phenomenological study should utilize at least six participants, this study utilized semi-structured interviews with 10 EFL learners to explore why and how they have experienced the motivation to learn English throughout their lives. The methodology of horizontalization was used to break the interview protocols into individual units of meaning before analyzing these units to extract the overarching themes (Moustakas, 1994). These themes were then interpreted into a detailed description of LLM as experienced by EFL students in this context. Finally, the resulting description was analyzed to discover how these learners’ lived experiences with LLM conformed with and/or diverged from current theories of LLM.
• The purpose of this qualitative, embedded, multiple case study was to examine how both parent-child attachment relationships are impacted by the quality of the paternal and maternal caregiver-child interactions that occur throughout a maternal deployment, within the context of dual-military couples. In order to examine this phenomenon, an embedded, multiple case study was conducted, utilizing an attachment systems metatheory perspective. The study included four dual-military couples who experienced a maternal deployment to Operation Iraqi Freedom (OIF) or Operation Enduring Freedom (OEF) when they had at least one child between 8 weeks-old to 5 years-old.  Each member of the couple participated in an individual, semi-structured interview with the researcher and completed the Parenting Relationship Questionnaire (PRQ). “The PRQ is designed to capture a parent’s perspective on the parent-child relationship” (Pearson, 2012, para. 1) and was used within the proposed study for this purpose. The PRQ was utilized to triangulate the data (Bekhet & Zauszniewski, 2012) as well as to provide some additional information on the parents’ perspective of the quality of the parent-child attachment relationship in regards to communication, discipline, parenting confidence, relationship satisfaction, and time spent together (Pearson, 2012). The researcher utilized the semi-structured interview to collect information regarding the parents' perspectives of the quality of their parental caregiver behaviors during the deployment cycle, the mother's parent-child interactions while deployed, the behavior of the child or children at time of reunification, and the strategies or behaviors the parents believe may have contributed to their child's behavior at the time of reunification. The results of this study may be utilized by the military, and by civilian providers, to develop proactive and preventive measures that both providers and parents can implement, to address any potential adverse effects on the parent-child attachment relationship, identified through the proposed study. The results of this study may also be utilized to further refine and understand the integration of attachment theory and systems theory, in both clinical and research settings, within the field of marriage and family therapy.

Purpose: As a scoping review, evaluate the literature on the presentations, genetics, and therapies for neuroblastoma in adult patients. Methods: We searched four databases for studies reporting adults with neuroblastoma. Cohort studies, case series, and case reports were synthesized qualitatively. Progression-free and overall survival were compared amongst cohort studies. Results: Of 2287 unique records, 136 studies published in 141 articles were included. A total of 679 patients were included. On review of individual patient-level data, the adrenal gland and retroperitoneum were the most common primary site (47.3%). MYCN was rarely amplified: seven studies reported zero patients with MYCN amplified, two studies with a single patient, and one study with 3/7 patients. Adult patients appear to show a high frequency of somatic mutations, specifically ALK (42%) and ATRX (58%). Registry data of included studies showed 5-year overall survival to be 36.3% in adults aged ≥20 years. Conclusion: Of nearly 700 cases of adult neuroblastoma published in the literature, the most common primary site is the adrenals or retroperitoneum. Relative to pediatric cases, adult cases demonstrate a considerable rate of somatic mutations such as ALK and ATRX. Registry data showed 5-year survival of 36%. Future studies evaluating targeted therapies in larger samples are needed.
