How to Write a Research Question: Types, Steps, and Examples

A note from the author, Imed Bouchrika, PhD, career planning and academic research expert:

From conducting preliminary literature reviews to collecting data, every part of the research process relies on a research question. As an expert with more than 10 years of experience in academic research and writing, I know well that identifying a research question can be challenging even with primary and secondary research sources as the literature body continues to expand. Given this challenge, I have created this guide on how to create a good research question based on actual practices in the academe. Through this guide, I hope to impart knowledge that can help you in identifying a research question and also in creating a study that can significantly impact your field.

What is a Research Question?

A research question is a question that a study or research project, through its thesis statement, aims to answer. This question often addresses an issue or a problem, which, through analysis and interpretation of data, is answered in the study's conclusion. In most studies, the research question is written so that it outlines various aspects of the study, including the population and variables to be studied and the problem the study addresses.

As their name implies, a research question is often grounded on research. As a result, these questions are dynamic; this means researchers can change or refine the research question as they review related literature and develop a framework for the study. While many research projects will focus on a single research question, larger studies often use more than one research question.

Importance of the research question

The primary importance of developing a research question is that it narrows down a broad topic of interest into a specific area of study (Creswell, 2014). Research questions, along with hypotheses, also serve as a guiding framework for research. These questions also specifically reveal the boundaries of the study, setting its limits, and ensuring cohesion.

Moreover, the research question has a domino effect on the rest of the study. These questions influence factors, such as the research methodology, sample size, data collection, and data analysis (Lipowski, 2008).

Types of Research Questions

Research questions can be classified into different categories, depending on the type of research to be done. Knowing what type of research one wants to do—quantitative, qualitative, or mixed-methods studies—can help in writing effective research questions.

Doody and Bailey (2016) suggest a number of common types of research questions, as outlined below.

Quantitative research questions

Quantitative research questions are precise. These questions typically include the population to be studied, dependent and independent variables, and the research design to be used. They are usually framed and finalized at the start of the study (Berger, 2015).

Quantitative research questions also establish a link between the research question and the research design. Moreover, these questions are not answerable with "yes" or "no" responses. As a result, quantitative research questions don't use words such as "is," "are," "do," or "does."

Quantitative research questions usually seek to understand particular social, familial, or educational experiences or processes that occur in a particular context and/or location (Marshall & Rossman, 2011). They can be further categorized into three types: descriptive, comparative, and relationship.

  • Descriptive research questions aim to measure the responses of a study's population to one or more variables or describe variables that the research will measure. These questions typically begin with "what". Students aim for a what is research question to uncover particular processes.
  • Comparative research questions aim to discover the differences between two or more groups for an outcome variable. These questions can be causal, as well. For instance, the researcher may compare a group where a certain variable is involved and another group where that variable is not present.
  • Relationship research questions seek to explore and define trends and interactions between two or more variables. This research question design often includes both dependent and independent variables and use words such as "association" or "trends."

Qualitative research questions

Qualitative research questions may concern broad areas of research or more specific areas of study. Similar to quantitative research questions, qualitative research questions are linked to research design. Unlike their quantitative counterparts, though, qualitative research questions are usually adaptable, non-directional, and more flexible (Creswell, 2013). As a result, studies using these questions generally aim to "discover," "explain," or "explore."

Ritchie et al. (2014) and Marshall and Rossman (2011) have also further categorized qualitative research questions into a number of types, as listed below:

  • Contextual research questions seek to describe the nature of what already exists.
  • Descriptive research questions attempt to describe a phenomenon.
  • Emancipatory research questions aim to produce knowledge that allows for engagement in social action, especially for the benefit of disadvantaged people.
  • Evaluative research questions assess the effectiveness of existing methods or paradigms.
  • Explanatory research questions seek to expound on a phenomenon or examine reasons for and associations between what exists.
  • Exploratory research questions investigate little-known areas of a particular topic.
  • Generative research questions aim to provide new ideas for the development of theories and actions.
  • Ideological research questions are used in research that aims to advance specific ideologies of a position.

The following table illustrates the differences between quantitative and qualitative research questions.

Example: Factors that increase the likelihood of childhood anxiety include peer pressure, genetics, and higher intelligence levels.
Topicchildhood anxiety
Key aspects of the topic to be discussedpeer pressure, parental education, and higher intelligence levels

Mixed-methods studies

Mixed-methods studies typically require a set of both quantitative and qualitative research questions. Separate questions are appropriate when the mixed-methods study focuses on the significance and differences in quantitative and qualitative methods and not on the study's integrative component (Tashakkori & Teddlie, 2010).

Researchers also have the option to develop a single mixed-methods research question. According to Tashakkori and Teddlie (2010), this suggests an integrative process or component between the study's quantitative and qualitative research methods.

Steps to Developing a Good Research Question

Before learning how to write a research paper, you must first learn how to create a research question. Based on the research question definition provided, formulate your query. If you are looking for criteria for a good research question, Stone (2002) says that a good research question should be relevant, decided, and meaningful. Creating a research question can be a tricky process, but there is a specific method you can follow to ease the process.

The following steps will guide you on how to formulate a research question:

1. Start with a broad topic.

A broad topic provides writers with plenty of avenues to explore in their search for a viable research question. Techniques to help you develop a topic into subtopics and potential research questions include brainstorming and concept mapping. For example, you can raise thought-provoking questions with your friends and flesh out ideas from your discussions. These techniques can organize your thoughts so you can identify connections and relevant themes within a broad topic.

When searching for a topic, it's wise to choose an area of study that you are genuinely interested in, since your interest in a topic will affect your motivation levels throughout your research. It's also wise to consider the interests being addressed recently by the research community, as this may affect your paper’s chances of getting published.

2. Do preliminary research to learn about topical issues.

Once you have picked a topic, you can start doing preliminary research. This initial stage of research accomplishes two goals. First, a preliminary review of related literature allows you to discover issues that are currently being discussed by scholars and fellow researchers. This way, you get up-to-date, relevant knowledge on your topic.

Second, a preliminary review of related literature allows you to spot existing gaps or limitations in existing knowledge of your topic. With a certain amount of fine-tuning, you can later use these gaps as the focus of your research question.

Moreover, according to Farrugia et al. (2010), certain institutions that provide grants encourage applicants to conduct a systematic review of available studies and evidence to see if a similar, recent study doesn't already exist, before applying for a grant.

3. Narrow down your topic and determine potential research questions.

Once you have gathered enough knowledge on the topic you want to pursue, you can start focusing on a more specific area of study and narrowing down a research question. One option is to focus on gaps in existing knowledge or recent literature. Referred to by Sandberg and Alvesson (2011) as "gap-spotting," this method involves constructing research questions out of identified limitations in literature and overlooked areas of study. Similarly, researchers can choose research questions that extend or complement the findings of existing literature.

Another way of identifying and constructing research questions: problematization (Sandberg & Alvesson, 2011). As a research question methodology, problematization aims to challenge and scrutinize assumptions that support others' and the researcher's theoretical position. This means constructing research questions that challenge your views or knowledge of the area of study.

Lipowski (2008), on the other hand, emphasizes the importance of taking into consideration the researcher's personal experiences in the process of developing a research question. Researchers who are also practitioners, for instance, can reflect on problematic areas of their practice. Patterns and trends in practice may also provide new insights and potential research question examples.

4. Evaluate the soundness of your research question.

At this point, you should have a list of potential research questions to choose from. To narrow them down, you have to evaluate each potential option based on their soundness, which can mean a number of things. Aside from being clear or specific, a good research question will also need to be relevant. There are other factors to consider when choosing which research question to investigate. To create a better play-by-play, here are the most crucial characteristics of the research question that you are looking for according to Hulley et al. (2007) known as the "FINER" criteria to find out if you have a good research question. The FINER criteria are outlined below:

F - Feasible
A good research question is feasible, which means that the question is well within the researcher's ability to investigate. Researchers should be realistic about the scale of their research as well as their ability to collect data and complete the research with their skills and the resources available to them. It's also wise to have a contingency plan in place in case problems arise.

I - Interesting
The ideal research question is interesting not only to the researcher but also to their peers and community. This interest boosts the researcher's motivation to see the question answered. For instance, you can do research on student housing trends if it is right up your alley, as they do change often.

N - Novel
Your research question should be developed to bring new insights to the field of study you are investigating. The question may confirm or extend previous findings on the topic you are researching, for instance.

E - Ethical
This is one of the more important considerations of making a research question. Your research question and your subsequent study must be something that review boards and the appropriate authorities will approve.

R - Relevant
Aside from being interesting and novel, the research question should be relevant to the scientific community and people involved in your area of study. If possible, your research question should also be relevant to the public's interest.

5. Construct your research question properly.

Considering research question importance, research questions should be structured properly to ensure clarity. Look for good research questions examples. There are a number of frameworks that you can use for properly constructing a research question. The two most commonly used frameworks are explained below.

PICOT framework

The PICOT research question framework was first introduced in 1995 by Richardson et al. Using the PICOT framework, research questions can be constructed to address important elements of the study, including the population to be studied, the expected outcomes, and the time it takes to achieve the outcome. With these elements, the framework is more commonly used in clinical research and evidence-based studies.

  • P - population, patients, or problem
  • I - intervention or indicator being studied
  • C - comparison group
  • O - outcome of interest
  • T - timeframe of the study

The sample research question below illustrates how to write research questions based on the PICOT framework and its elements:

Between the ages of five and 18, are children of parents with diagnosed mental health issues at increased risk of depression or anxiety compared with children of parents with no diagnosed mental health issues?
P (population being studied)children
I (indicator or intervention)parents with diagnosed mental health issues
C (comparison group)children of parents with no diagnosed mental health issues
O (outcome of interest)increased risk of depression or anxiety
T (timeframe of interest)between the ages of five and 18

PEO framework

Like the PICOT framework, the PEO framework is commonly used in clinical studies as well. However, this framework is more useful for qualitative research questions. This framework includes these elements:

  • P - population being studied
  • E - exposure to preexisting conditions
  • O - outcome of interest

Below is an example of research question in the PEO framework:

Journal Article Reporting Standards (JARS)

6. DiscussionStatement of support or nonsupport for all original hypotheses;

Other commonly used frameworks for research questions include the SPIDER (Sample, Phenomenon of Interest, Design, Evaluation, Research type) and CLIP (Client group, Location of provided service, Improvement/Information/Innovation, Professionals) frameworks. Aside from helping researchers properly structure research questions, these frameworks also help refine research results and improve the focus of data analysis.

Examples of Good and Bad Research Questions

The following research question examples can further guide researchers on properly constructing a research question.

Example no. 1

Bad: How does social media affect people's behavior?
Good: What effect does the daily use of YouTube have on the attention span of children aged under 16?

The first research question is considered bad because of the vagueness of "social media" as a concept and the question's lack of specificity. A good research question should be specific and focused, and its answer should be discovered through data collection and analysis. You can also hone your ability to construct well-worded and specific research questions by improving reading skills.

Example no. 2

Bad: Has there been an increase in childhood obesity in the US in the past 10 years?
Good: How have school intervention programs and parental education levels affected the rate of childhood obesity among 1st to 6th-grade students?

In the second example, the first research question is not ideal because it's too simple, and it's easily answerable by a "yes" or "no." The second research question is more complicated; to answer it, the researcher must collect data, perform in-depth data analysis, and form an argument that leads to further discussion.

Important Points to Keep in Mind in Creating a Research Question

Developing the right research question is a critical first step in the research process. The examples of research questions provided in this guide have illustrated what good research questions look like. The key points outlined below should help researchers in the pursuit:

  • The development of a research question is an iterative process that involves continuously updating one's knowledge on the topic and refining ideas at all stages (Maxwell, 2013).
  • Remain updated on current trends, state-of-the-art research studies, and technological advances in the field of study you are pursuing.
  • Make the research question as specific and concise as possible to ensure clarity. Avoid using words or terms that don't add to the meaning of the research question.
  • Aside from doing a literature review, seek the input of experts in the field, mentors, and colleagues. Such inputs can prove beneficial not only for the research question but also for creating the rest of the study.
  • Finally, refrain from committing the two most common mistakes in framing research questions: posing a question as an anticipated contribution and framing a question as a method (Mayo et al., 2013).
