How to Write a Statement of a Problem in Research with Steps

Published by Grace Graffin at August 11th, 2021 , Revised On October 3, 2023

Research is a systematic investigation to find new techniques, products or processes to solve problems. Apart from being systematic, research is empirical in nature: it’s based on observations and measurement of those observations.

It’s what comes before the development. Impacts and policies that are born in society are borne out of the research.

The most important step to perform any research is to identify a problem that needs to be solved. Therefore, it is necessary to define a research problem before starting the actual research process. Once a research problem has been identified, the next step is to write a problem statement.

Philosopher Kaoru Ishikawa said: “You will have a problem half-solved by defining it correctly on the first day.”

This quote perfectly reflects the importance of a problem statement in research. Before writing a problem statement, it is essential to pinpoint a specific problem, the difficulties you can expect to face as you try to solve it and the research gaps you aim to fill with your research.

The last part—how your research aims to fill a gap in the existing literature—will act as a springboard to the solution(s) that policy makers, for instance, might eventually take to solve that problem.

Filling a gap, therefore, is very important towards solving an existing problem.

What is a Problem Statement?

A problem statement is a clear and concise description of an issue or challenge that needs to be addressed. It typically outlines the existing gap between the current state (what currently is) and the desired state (what should be). Crafting a well-defined problem statement is critical for problem-solving, research, or project planning, as it serves as a guidepost and sets the direction for the subsequent steps.

Research Problem and Research Method – A Cyclical Process

The type of research strategy used in research determines whether you will be analysing theoretical problems to add value to existing knowledge, discussing practical issues to become an agent of change for an organisation or industry or looking at both aspects in relation to any given problem.

However, the kind of problem you aim to tackle with your research, to begin with, will also help you narrow down which research design , method or strategy to opt for.

This is therefore a cyclical process. Your research aim guides your research design can help you focus on a specific kind of research gap/problem.

However, generally, your research will focus on one or the other.

Here is all you need to know about how to write a statement of the problem in research, also called problem statement by some research writers .

Why do you Need a Statement of the Problem, to Begin with?

You need a statement of the problem to transform a generalised problem into a well-defined, brief, targeted statement to perform research in the decision-making process. The problem statement helps the researcher to identify the purpose of the ongoing research.

The problem statement in the dissertation is the pillar of the introduction chapter through which the reader can understand the research questions and scope of the project. If you do not define the problem statement properly, the results might become unmanageable.

Writing Problem Statement for a Business or Organisation

In the business world, problem statements provide the basis for the enhancement and refinement of projects. Without identifying and understanding the problem, it will be hard to find and effectively implement solutions.

A stand-alone document that solely provides an in-depth and detailed problem statement is usually the answer for organisations and businesses when it becomes imperative to find the solution to a problem.

Problem Statement – How to Write it

Ask yourself the following questions before writing the problem statement:

• What is wrong in the research area/subarea XYZ?
• Where did it happen?
• When did it happen?
• To what extent (how much)?
• I know that because…(evidence)

‘What’ always defines the defect of the problem at hand and explains why it matters? ‘Where’ defines the geological location of the problem. ‘When’ defines the history and the pattern of the problem, the goal of the stated problem and the scope of research.

‘How much’ defines the trend of the problem as to how many objects are facing the same defect and to what extent. The last part, ‘I know this because…’, will help the researcher identify the standard(s) that he must meet.

Step 1: Understanding the Problem

The problem statement should provide a clear and concise background to the research problem you are investigating. Before starting your research , review the literature about the specific problem and find a gap to fill with your own research.

Practical Research Problem Statement

If you are doing experimental research , you can identify problems by talking to people working in a relevant field, studying research reports, and reviewing previous research. Here are some examples of practical research problems:

• A problem that hinders the efficiency of a company
• An institutional process that needs interventions
• An area of concern in your field/sub-field of interest
• Members of a society facing a specific difficulty

The problem statement should focus on the details related to the problem, such as:

• When and where was the problem observed?
• Who is/are affected by it?
• What research has been conducted and what practical steps have been taken to resolve the problem?

Example of Practical Research Problem Statement

The production of a company is low for the months of July and August every year. Initial research has been conducted by the company, which revealed poor production in July and August is due to the unavailability of local raw material.

The company has made some effective attempts at engaging the local suppliers to ensure an uninterrupted supply of the raw material, but these efforts are yet to have any significant impact on the production levels.

Theoretical Research Problem Statement

According to USC Libraries, “A theoretical framework consists of concepts and, together with their definitions and reference to relevant scholarly literature, existing theory that is used for your particular study…theoretical framework must demonstrate an understanding of theories and concepts…relevant to the topic of your research paper and that relate to the broader areas of knowledge being considered.”

The theoretical research indirectly contributes to the change by identifying the problem, expanding knowledge and improving understanding. The researcher can find a specific problem by brainstorming the topic and reviewing already published theories and research.

When writing a problem statement based on a theoretical research problem , it is important to recognise the historical, geographical, social and scientific background. Here are the elements of the theoretical problem statement framework that you should consider:

• What are the facts about the problem?
• Does the problem relate to a certain geographical area or time period?
• How is the problem discussed and explained in the existing literature?

Example of Theoretical Research Problem Statement

The production of a company is low for July and August every year. Initial research has been conducted by the company, which revealed poor production in July and August is due to the unavailability of local raw material. The company has made some effective attempts to engage the local suppliers to ensure an uninterrupted raw material supply. Still, these efforts are yet to have any significant impact on the production levels.

Step 2 – Show why it’s Important and Relevant

By discussing the importance of the problem under investigation, you are demonstrating the relevance of your research. However, this does not mean that you will end up discovering something unimaginable or extraordinary.

The objective here is to clearly state how and why your research problem is relevant in your chosen area of study and why it requires further research.

As indicated previously, practical research deals with a problem affecting society, social group, firm or organisation on a broader scale. To elaborate on why it is important to solve this problem and why your research is significant, you could consider the following questions:

• What will be the consequences if the problem remains unsolved?
• Who do these consequences have the most implications for?
• What is the wider relevance of the problem being investigated?

Low production in July and August negatively affects the company’s marketing capital, thereby becoming an area of deep concern for the directors and stakeholders. The marketing budget cut in July and August is hindering its ability to promote its products uninterruptedly.

Addressing this problem will have practical benefits for the company and help establish the reasons for disruption in raw material supply.

The relevance of all theoretical issues may not be too obvious, even though most theoretical problems do have practical implications. Here are some questions for you to ponder to establish the importance of your research problem:

• Will your research help to advance understanding of the topic under investigation?
• Are there any benefits of you resolving the problem for other researchers who wish to explore this topic further in the future?
• What are the direct or indirect implications (s) of the problem you are trying to solving?

The new forms of employment such as freelance, contract-based work and zero-hour work arrangements are recognised as either a manipulative last option or a flexible active choice. It is necessary to conduct comprehensive qualitative research to uncover why fresh graduates take up these types of employment in the gig economy. There is a need to advance more vigorous concepts relating to instability and flexibility in modern forms of employment from employees’ perspectives, which will also help shape future policies.

Step 3 – Declaring the Problem

Before you jump on to state your research’s problem statements, it’s important to devote a sentence or two to let your readers know the precise, narrowed-down research problem you will be discussing about.

For language clarity purposes, here are some strong opening statements to achieve this step:

• Recently, there has been growing interest in …
• The possibility of…has generated wide interest in …
• The development of…is a classic problem in…
• The development of…has led to the hope that …
• The…has become a favourite topic for analysis …
• Knowledge of…has great importance for …
• The study of…has become an important aspect of …
• A central issue in…is…
• The…has been extensively studied in recent years.
• Many investigators have recently turned to …
• The relationship between…has been investigated by many researchers.
• Many recent studies have found out…

Step 4 – Establishing Aim and Objectives

The last step in writing a problem statement is to provide a framework for solving the problem. This will help you, the researcher, stay focused on your research aims and not stray; it will also help you readers keep in mind the reason as to why you conducted this study, to begin with.

A good problem statement does not provide the exact solution to any problem. Rather, it focuses more on how to effectively understand or tackle a problem by establishing the possible causes.

The aim of a research study is its end goal or overall purpose. Following are some examples of how you can craft your research aim statements:

• This research study aims to investigate…
• This paper is aimed at exploring…
• This research aims to identify…

On the other hand, objectives are the smaller steps that a researcher must take to address the aim of the research. Once you have laid out the research problem your research will deal with, it’s important to next mention the how behind that. Objectives are mostly imperative statements, often beginning with transitive verbs like ‘to analyse,’ ‘to investigate,’ etc.

Some more examples are:

• Statistical analysis will be conducted to determine…
• Both quantitative and qualitative research methods will be employed to probe…
• Face-to-face interviews will be carried out with the participants to establish…

Practical Research Aim and Objectives

This project aims to identify the causes of disturbed supply of raw material in the region, which resulted in low production for the company in July and August. This will be achieved by conducting interviews and surveys with the suppliers to understand why the supply is unpredictable in those two months and what can be done to ensure orderliness. Practical experiments will also be conducted to observe the effectiveness of proposed solutions.

Theoretical Research Aim and Objectives

This study aims to understand and unearth the experiences of fresh graduates in the modern economy. The sample population will participate in this study through qualitative research methods, which are expected to provide a deeper insight into the perceptions and motives of these fresh graduates working as freelancers and contract-based employees. The data collected from this exercise and the existing literature on the topic will be analysed in statistical analysis software.

TIP: Search the common themes of the problem statement in your field of research before writing a problem statement.

Problem Statement versus Significance of the Study

Even though both may sound similar, the statement of the problem and the significance of your study are going to be different. The latter does develop upon and from the former, though.

The problem statement tells your readers what’s wrong, whereas the significance of the study will tell them how your research contributed to that problem. You can’t have a significance of a study without mentioning the problem statement first.

Furthermore, signifying your study implies mentioning 4 key points related to it:

• How your study will further develop the theory behind the existing problem
• Practical solutions that might be implemented to solve the problem (especially in field research work)
• Whether your study or research will pave way for innovative methods to solve the existing problem.
• How your study can help in policy making and implementation, impact studies, etc.

Problem statement in research is the description of an existing issue that needs to be addressed. The problem statement is a focal point of any research and a bridge between the  literature review  and the  research methodology .

Problem statement often has three elements; the problem itself, the method of solving the problem, and the purpose. There are five aspects of every problem: What, Where, When, to what extent, and what defects you know about the topic. Here is an  example of a problem statement in a research proposal  for your better understanding.

If you wish to know more about how to start your research process, then you might want to take a look at the “ Starting the Research Process ” section on our website, which has several articles relating to a  research problem , problem statement, research aim and objectives, and  research proposal .

What is a Research Hypothesis: How to Write it, Types, and Examples

Any research begins with a research question and a research hypothesis . A research question alone may not suffice to design the experiment(s) needed to answer it. A hypothesis is central to the scientific method. But what is a hypothesis ? A hypothesis is a testable statement that proposes a possible explanation to a phenomenon, and it may include a prediction. Next, you may ask what is a research hypothesis ? Simply put, a research hypothesis is a prediction or educated guess about the relationship between the variables that you want to investigate.  

It is important to be thorough when developing your research hypothesis. Shortcomings in the framing of a hypothesis can affect the study design and the results. A better understanding of the research hypothesis definition and characteristics of a good hypothesis will make it easier for you to develop your own hypothesis for your research. Let’s dive in to know more about the types of research hypothesis , how to write a research hypothesis , and some research hypothesis examples .  

Table of Contents

What is a hypothesis ?  

A hypothesis is based on the existing body of knowledge in a study area. Framed before the data are collected, a hypothesis states the tentative relationship between independent and dependent variables, along with a prediction of the outcome.  

What is a research hypothesis ?  

Young researchers starting out their journey are usually brimming with questions like “ What is a hypothesis ?” “ What is a research hypothesis ?” “How can I write a good research hypothesis ?”   

A research hypothesis is a statement that proposes a possible explanation for an observable phenomenon or pattern. It guides the direction of a study and predicts the outcome of the investigation. A research hypothesis is testable, i.e., it can be supported or disproven through experimentation or observation.     

Characteristics of a good hypothesis  

Here are the characteristics of a good hypothesis :  

• Clearly formulated and free of language errors and ambiguity  
• Concise and not unnecessarily verbose  
• Has clearly defined variables  
• Testable and stated in a way that allows for it to be disproven  
• Can be tested using a research design that is feasible, ethical, and practical   
• Specific and relevant to the research problem  
• Rooted in a thorough literature search  
• Can generate new knowledge or understanding

How to create an effective research hypothesis  

A study begins with the formulation of a research question. A researcher then performs background research. This background information forms the basis for building a good research hypothesis . The researcher then performs experiments, collects, and analyzes the data, interprets the findings, and ultimately, determines if the findings support or negate the original hypothesis.  

Let’s look at each step for creating an effective, testable, and good research hypothesis :  

• Identify a research problem or question: Start by identifying a specific research problem.   
• Review the literature: Conduct an in-depth review of the existing literature related to the research problem to grasp the current knowledge and gaps in the field.   
• Formulate a clear and testable hypothesis : Based on the research question, use existing knowledge to form a clear and testable hypothesis . The hypothesis should state a predicted relationship between two or more variables that can be measured and manipulated. Improve the original draft till it is clear and meaningful.  
• State the null hypothesis: The null hypothesis is a statement that there is no relationship between the variables you are studying.   
• Define the population and sample: Clearly define the population you are studying and the sample you will be using for your research.  
• Select appropriate methods for testing the hypothesis: Select appropriate research methods, such as experiments, surveys, or observational studies, which will allow you to test your research hypothesis .  

Remember that creating a research hypothesis is an iterative process, i.e., you might have to revise it based on the data you collect. You may need to test and reject several hypotheses before answering the research problem.  

How to write a research hypothesis  

When you start writing a research hypothesis , you use an “if–then” statement format, which states the predicted relationship between two or more variables. Clearly identify the independent variables (the variables being changed) and the dependent variables (the variables being measured), as well as the population you are studying. Review and revise your hypothesis as needed.  

An example of a research hypothesis in this format is as follows:  

“ If [athletes] follow [cold water showers daily], then their [endurance] increases.”  

Population: athletes  

Independent variable: daily cold water showers  

Dependent variable: endurance  

You may have understood the characteristics of a good hypothesis . But note that a research hypothesis is not always confirmed; a researcher should be prepared to accept or reject the hypothesis based on the study findings.  

Research hypothesis checklist  

Following from above, here is a 10-point checklist for a good research hypothesis :  

• Testable: A research hypothesis should be able to be tested via experimentation or observation.  
• Specific: A research hypothesis should clearly state the relationship between the variables being studied.  
• Based on prior research: A research hypothesis should be based on existing knowledge and previous research in the field.  
• Falsifiable: A research hypothesis should be able to be disproven through testing.  
• Clear and concise: A research hypothesis should be stated in a clear and concise manner.  
• Logical: A research hypothesis should be logical and consistent with current understanding of the subject.  
• Relevant: A research hypothesis should be relevant to the research question and objectives.  
• Feasible: A research hypothesis should be feasible to test within the scope of the study.  
• Reflects the population: A research hypothesis should consider the population or sample being studied.  
• Uncomplicated: A good research hypothesis is written in a way that is easy for the target audience to understand.  

By following this research hypothesis checklist , you will be able to create a research hypothesis that is strong, well-constructed, and more likely to yield meaningful results.  

Types of research hypothesis  

Different types of research hypothesis are used in scientific research:  

1. Null hypothesis:

A null hypothesis states that there is no change in the dependent variable due to changes to the independent variable. This means that the results are due to chance and are not significant. A null hypothesis is denoted as H0 and is stated as the opposite of what the alternative hypothesis states.   

Example: “ The newly identified virus is not zoonotic .”  

2. Alternative hypothesis:

This states that there is a significant difference or relationship between the variables being studied. It is denoted as H1 or Ha and is usually accepted or rejected in favor of the null hypothesis.  

Example: “ The newly identified virus is zoonotic .”  

3. Directional hypothesis :

This specifies the direction of the relationship or difference between variables; therefore, it tends to use terms like increase, decrease, positive, negative, more, or less.   

Example: “ The inclusion of intervention X decreases infant mortality compared to the original treatment .”   

4. Non-directional hypothesis:

While it does not predict the exact direction or nature of the relationship between the two variables, a non-directional hypothesis states the existence of a relationship or difference between variables but not the direction, nature, or magnitude of the relationship. A non-directional hypothesis may be used when there is no underlying theory or when findings contradict previous research.  

Example, “ Cats and dogs differ in the amount of affection they express .”  

5. Simple hypothesis :

A simple hypothesis only predicts the relationship between one independent and another independent variable.  

Example: “ Applying sunscreen every day slows skin aging .”  

6 . Complex hypothesis :

A complex hypothesis states the relationship or difference between two or more independent and dependent variables.   

Example: “ Applying sunscreen every day slows skin aging, reduces sun burn, and reduces the chances of skin cancer .” (Here, the three dependent variables are slowing skin aging, reducing sun burn, and reducing the chances of skin cancer.)  

7. Associative hypothesis:  

An associative hypothesis states that a change in one variable results in the change of the other variable. The associative hypothesis defines interdependency between variables.  

Example: “ There is a positive association between physical activity levels and overall health .”  

8 . Causal hypothesis:

A causal hypothesis proposes a cause-and-effect interaction between variables.  

Example: “ Long-term alcohol use causes liver damage .”  

Note that some of the types of research hypothesis mentioned above might overlap. The types of hypothesis chosen will depend on the research question and the objective of the study.  

Research hypothesis examples  

Here are some good research hypothesis examples :  

“The use of a specific type of therapy will lead to a reduction in symptoms of depression in individuals with a history of major depressive disorder.”  

“Providing educational interventions on healthy eating habits will result in weight loss in overweight individuals.”  

“Plants that are exposed to certain types of music will grow taller than those that are not exposed to music.”  

“The use of the plant growth regulator X will lead to an increase in the number of flowers produced by plants.”  

Characteristics that make a research hypothesis weak are unclear variables, unoriginality, being too general or too vague, and being untestable. A weak hypothesis leads to weak research and improper methods.   

Some bad research hypothesis examples (and the reasons why they are “bad”) are as follows:  

“This study will show that treatment X is better than any other treatment . ” (This statement is not testable, too broad, and does not consider other treatments that may be effective.)  

“This study will prove that this type of therapy is effective for all mental disorders . ” (This statement is too broad and not testable as mental disorders are complex and different disorders may respond differently to different types of therapy.)  

“Plants can communicate with each other through telepathy . ” (This statement is not testable and lacks a scientific basis.)  

Importance of testable hypothesis  

If a research hypothesis is not testable, the results will not prove or disprove anything meaningful. The conclusions will be vague at best. A testable hypothesis helps a researcher focus on the study outcome and understand the implication of the question and the different variables involved. A testable hypothesis helps a researcher make precise predictions based on prior research.  

To be considered testable, there must be a way to prove that the hypothesis is true or false; further, the results of the hypothesis must be reproducible.  

Frequently Asked Questions (FAQs) on research hypothesis  

1. What is the difference between research question and research hypothesis ?  

A research question defines the problem and helps outline the study objective(s). It is an open-ended statement that is exploratory or probing in nature. Therefore, it does not make predictions or assumptions. It helps a researcher identify what information to collect. A research hypothesis , however, is a specific, testable prediction about the relationship between variables. Accordingly, it guides the study design and data analysis approach.

2. When to reject null hypothesis ?

A null hypothesis should be rejected when the evidence from a statistical test shows that it is unlikely to be true. This happens when the test statistic (e.g., p -value) is less than the defined significance level (e.g., 0.05). Rejecting the null hypothesis does not necessarily mean that the alternative hypothesis is true; it simply means that the evidence found is not compatible with the null hypothesis.  

3. How can I be sure my hypothesis is testable?  

A testable hypothesis should be specific and measurable, and it should state a clear relationship between variables that can be tested with data. To ensure that your hypothesis is testable, consider the following:  

• Clearly define the key variables in your hypothesis. You should be able to measure and manipulate these variables in a way that allows you to test the hypothesis.  
• The hypothesis should predict a specific outcome or relationship between variables that can be measured or quantified.   
• You should be able to collect the necessary data within the constraints of your study.  
• It should be possible for other researchers to replicate your study, using the same methods and variables.   
• Your hypothesis should be testable by using appropriate statistical analysis techniques, so you can draw conclusions, and make inferences about the population from the sample data.  
• The hypothesis should be able to be disproven or rejected through the collection of data.  

4. How do I revise my research hypothesis if my data does not support it?  

If your data does not support your research hypothesis , you will need to revise it or develop a new one. You should examine your data carefully and identify any patterns or anomalies, re-examine your research question, and/or revisit your theory to look for any alternative explanations for your results. Based on your review of the data, literature, and theories, modify your research hypothesis to better align it with the results you obtained. Use your revised hypothesis to guide your research design and data collection. It is important to remain objective throughout the process.  

5. I am performing exploratory research. Do I need to formulate a research hypothesis?  

As opposed to “confirmatory” research, where a researcher has some idea about the relationship between the variables under investigation, exploratory research (or hypothesis-generating research) looks into a completely new topic about which limited information is available. Therefore, the researcher will not have any prior hypotheses. In such cases, a researcher will need to develop a post-hoc hypothesis. A post-hoc research hypothesis is generated after these results are known.  

6. How is a research hypothesis different from a research question?

A research question is an inquiry about a specific topic or phenomenon, typically expressed as a question. It seeks to explore and understand a particular aspect of the research subject. In contrast, a research hypothesis is a specific statement or prediction that suggests an expected relationship between variables. It is formulated based on existing knowledge or theories and guides the research design and data analysis.

7. Can a research hypothesis change during the research process?

Yes, research hypotheses can change during the research process. As researchers collect and analyze data, new insights and information may emerge that require modification or refinement of the initial hypotheses. This can be due to unexpected findings, limitations in the original hypotheses, or the need to explore additional dimensions of the research topic. Flexibility is crucial in research, allowing for adaptation and adjustment of hypotheses to align with the evolving understanding of the subject matter.

8. How many hypotheses should be included in a research study?

The number of research hypotheses in a research study varies depending on the nature and scope of the research. It is not necessary to have multiple hypotheses in every study. Some studies may have only one primary hypothesis, while others may have several related hypotheses. The number of hypotheses should be determined based on the research objectives, research questions, and the complexity of the research topic. It is important to ensure that the hypotheses are focused, testable, and directly related to the research aims.

9. Can research hypotheses be used in qualitative research?

Yes, research hypotheses can be used in qualitative research, although they are more commonly associated with quantitative research. In qualitative research, hypotheses may be formulated as tentative or exploratory statements that guide the investigation. Instead of testing hypotheses through statistical analysis, qualitative researchers may use the hypotheses to guide data collection and analysis, seeking to uncover patterns, themes, or relationships within the qualitative data. The emphasis in qualitative research is often on generating insights and understanding rather than confirming or rejecting specific research hypotheses through statistical testing.

Research Questions & Hypotheses

Generally, in quantitative studies, reviewers expect hypotheses rather than research questions. However, both research questions and hypotheses serve different purposes and can be beneficial when used together.

Research Questions

Clarify the research’s aim (farrugia et al., 2010).

• Research often begins with an interest in a topic, but a deep understanding of the subject is crucial to formulate an appropriate research question.
• Descriptive: “What factors most influence the academic achievement of senior high school students?”
• Comparative: “What is the performance difference between teaching methods A and B?”
• Relationship-based: “What is the relationship between self-efficacy and academic achievement?”
• Increasing knowledge about a subject can be achieved through systematic literature reviews, in-depth interviews with patients (and proxies), focus groups, and consultations with field experts.
• Some funding bodies, like the Canadian Institute for Health Research, recommend conducting a systematic review or a pilot study before seeking grants for full trials.
• The presence of multiple research questions in a study can complicate the design, statistical analysis, and feasibility.
• It’s advisable to focus on a single primary research question for the study.
• The primary question, clearly stated at the end of a grant proposal’s introduction, usually specifies the study population, intervention, and other relevant factors.
• The FINER criteria underscore aspects that can enhance the chances of a successful research project, including specifying the population of interest, aligning with scientific and public interest, clinical relevance, and contribution to the field, while complying with ethical and national research standards.
• The P ICOT approach is crucial in developing the study’s framework and protocol, influencing inclusion and exclusion criteria and identifying patient groups for inclusion.
• Defining the specific population, intervention, comparator, and outcome helps in selecting the right outcome measurement tool.
• The more precise the population definition and stricter the inclusion and exclusion criteria, the more significant the impact on the interpretation, applicability, and generalizability of the research findings.
• A restricted study population enhances internal validity but may limit the study’s external validity and generalizability to clinical practice.
• A broadly defined study population may better reflect clinical practice but could increase bias and reduce internal validity.
• An inadequately formulated research question can negatively impact study design, potentially leading to ineffective outcomes and affecting publication prospects.

Checklist: Good research questions for social science projects (Panke, 2018)

Research Hypotheses

Present the researcher’s predictions based on specific statements.

• These statements define the research problem or issue and indicate the direction of the researcher’s predictions.
• Formulating the research question and hypothesis from existing data (e.g., a database) can lead to multiple statistical comparisons and potentially spurious findings due to chance.
• The research or clinical hypothesis, derived from the research question, shapes the study’s key elements: sampling strategy, intervention, comparison, and outcome variables.
• Hypotheses can express a single outcome or multiple outcomes.
• After statistical testing, the null hypothesis is either rejected or not rejected based on whether the study’s findings are statistically significant.
• Hypothesis testing helps determine if observed findings are due to true differences and not chance.
• Hypotheses can be 1-sided (specific direction of difference) or 2-sided (presence of a difference without specifying direction).
• 2-sided hypotheses are generally preferred unless there’s a strong justification for a 1-sided hypothesis.
• A solid research hypothesis, informed by a good research question, influences the research design and paves the way for defining clear research objectives.

Types of Research Hypothesis

• In a Y-centered research design, the focus is on the dependent variable (DV) which is specified in the research question. Theories are then used to identify independent variables (IV) and explain their causal relationship with the DV.
• Example: “An increase in teacher-led instructional time (IV) is likely to improve student reading comprehension scores (DV), because extensive guided practice under expert supervision enhances learning retention and skill mastery.”
• Hypothesis Explanation: The dependent variable (student reading comprehension scores) is the focus, and the hypothesis explores how changes in the independent variable (teacher-led instructional time) affect it.
• In X-centered research designs, the independent variable is specified in the research question. Theories are used to determine potential dependent variables and the causal mechanisms at play.
• Example: “Implementing technology-based learning tools (IV) is likely to enhance student engagement in the classroom (DV), because interactive and multimedia content increases student interest and participation.”
• Hypothesis Explanation: The independent variable (technology-based learning tools) is the focus, with the hypothesis exploring its impact on a potential dependent variable (student engagement).
• Probabilistic hypotheses suggest that changes in the independent variable are likely to lead to changes in the dependent variable in a predictable manner, but not with absolute certainty.
• Example: “The more teachers engage in professional development programs (IV), the more their teaching effectiveness (DV) is likely to improve, because continuous training updates pedagogical skills and knowledge.”
• Hypothesis Explanation: This hypothesis implies a probable relationship between the extent of professional development (IV) and teaching effectiveness (DV).
• Deterministic hypotheses state that a specific change in the independent variable will lead to a specific change in the dependent variable, implying a more direct and certain relationship.
• Example: “If the school curriculum changes from traditional lecture-based methods to project-based learning (IV), then student collaboration skills (DV) are expected to improve because project-based learning inherently requires teamwork and peer interaction.”
• Hypothesis Explanation: This hypothesis presumes a direct and definite outcome (improvement in collaboration skills) resulting from a specific change in the teaching method.
• Example : “Students who identify as visual learners will score higher on tests that are presented in a visually rich format compared to tests presented in a text-only format.”
• Explanation : This hypothesis aims to describe the potential difference in test scores between visual learners taking visually rich tests and text-only tests, without implying a direct cause-and-effect relationship.
• Example : “Teaching method A will improve student performance more than method B.”
• Explanation : This hypothesis compares the effectiveness of two different teaching methods, suggesting that one will lead to better student performance than the other. It implies a direct comparison but does not necessarily establish a causal mechanism.
• Example : “Students with higher self-efficacy will show higher levels of academic achievement.”
• Explanation : This hypothesis predicts a relationship between the variable of self-efficacy and academic achievement. Unlike a causal hypothesis, it does not necessarily suggest that one variable causes changes in the other, but rather that they are related in some way.

Tips for developing research questions and hypotheses for research studies

• Perform a systematic literature review (if one has not been done) to increase knowledge and familiarity with the topic and to assist with research development.
• Learn about current trends and technological advances on the topic.
• Seek careful input from experts, mentors, colleagues, and collaborators to refine your research question as this will aid in developing the research question and guide the research study.
• Use the FINER criteria in the development of the research question.
• Ensure that the research question follows PICOT format.
• Develop a research hypothesis from the research question.
• Ensure that the research question and objectives are answerable, feasible, and clinically relevant.

If your research hypotheses are derived from your research questions, particularly when multiple hypotheses address a single question, it’s recommended to use both research questions and hypotheses. However, if this isn’t the case, using hypotheses over research questions is advised. It’s important to note these are general guidelines, not strict rules. If you opt not to use hypotheses, consult with your supervisor for the best approach.
