Research Questions for Quantitative Research Proposals

Hey there, fellow college students! Are you feeling a bit lost when it comes to crafting research questions for your quantitative research proposal? Don’t worry – you’re not alone.

Many students find this part of the research process challenging, but it’s also one of the most important steps in setting up a successful study. In this guide, we’ll break down everything you need to know about creating effective research questions for quantitative research.

We’ll use everyday language and plenty of examples to help you understand the concepts better.

What Are Research Questions?

Let’s start with the basics. Research questions are the foundation of any good study. They’re like the GPS coordinates for your research journey – they tell you where you’re going and help you stay on track.


A research question is a clear, focused, and specific inquiry that your study aims to answer. It’s the main thing you want to find out through your research.


Why are research questions so crucial? Well, they:

  1. Guide your entire research process
  2. Help you choose the right methods and tools
  3. Keep you focused on what’s important
  4. Make it easier to organize and present your findings

Think of your research question as the main character in a movie. Everything else in your study – your methods, data collection, analysis, and conclusions – are supporting actors that help tell your research question’s story.

Characteristics of Good Quantitative Research Questions

Not all research questions are created equal. In quantitative research, where we’re dealing with numbers and measurable data, our questions need to have certain qualities to be effective.

1. Specific and Focused

A good research question zeroes in on a particular aspect of a topic. It’s not trying to solve world hunger in one go but might look at a specific factor related to it.

Example of a vague question: “How does social media affect students?”

Improved, specific question: “What is the relationship between daily Instagram use and academic performance among first-year college students?”

2. Measurable

In quantitative research, we need to be able to measure or quantify our variables. Your question should lead to data that can be analyzed statistically.

Example: “How does the number of hours spent studying per week correlate with GPA among undergraduate biology majors?”

3. Feasible

Can you actually answer this question with the time, resources, and access to data that you have? Be realistic about what you can accomplish.

Example of an unfeasible question: “What are the sleep patterns of every college student in the United States?”

More feasible question: “What are the average sleep duration and quality reported by students at XYZ University during final exam week?”

4. Relevant

Your question should contribute something meaningful to your field of study or address a gap in current knowledge.

Example: “How does the implementation of a mindfulness app affect self-reported stress levels among nursing students during clinical rotations?”

5. Ethical

Make sure your research question doesn’t lead to a study that could harm participants or violate ethical guidelines.

Example of an unethical question: “How do different levels of sleep deprivation affect exam performance in college students?”

More ethical alternative: “How do self-reported sleep habits correlate with exam performance in college students?”

Types of Quantitative Research Questions

Now that we know what makes a good research question let’s look at the different types you might encounter in quantitative research. Understanding these types can help you frame your own questions more effectively.

1. Descriptive Questions

Descriptive questions aim to provide a clear picture of a situation, phenomenon, or group. They often start with words like “what,” “who,” “where,” or “when.”

Example: “What is the average number of hours spent on social media per day among college freshmen?”

These questions are great for establishing baseline information or getting a snapshot of current conditions. They’re often used in surveys or observational studies.

2. Comparative Questions

Comparative questions look at differences between two or more groups or conditions. They usually involve words like “compare,” “contrast,” or “differ.”

Example: “How does the average GPA of student-athletes compare to non-athlete students at XYZ University?”

These questions are useful when you want to understand how different groups or conditions stack up against each other. They often lead to studies using t-tests or ANOVAs for analysis.

3. Relationship Questions

Relationship questions explore connections between variables. They typically use words like “relate,” “associate,” or “correlate.”

Example: “What is the relationship between hours of sleep per night and academic performance among college students?”

These questions are perfect for understanding how different factors might influence each other. They often lead to correlational studies or regression analyses.

4. Predictive Questions

Predictive questions try to forecast outcomes based on certain variables. They might use words like “predict,” “influence,” or “affect.”

Example: “To what extent can a student’s high school GPA and SAT scores predict their college GPA?”

These questions are great for understanding cause-and-effect relationships or for developing models to forecast future outcomes. They often involve regression analyses or more advanced statistical techniques.

5. Causal Questions

Causal questions aim to determine if one variable causes changes in another. They often use words like “effect,” “impact,” or “result.”

Example: “What is the effect of a 6-week mindfulness training program on stress levels among college students?”

These questions are the most challenging to address in quantitative research, as they require carefully controlled experimental designs to establish causality.

Steps to Develop Effective Research Questions

Alright, now that we’ve covered the types of questions, let’s walk through the process of creating your own killer research questions. Don’t worry – we’ll take it step by step!

1. Choose a Broad Topic

Start with a general area that interests you. It could be something like “student mental health,” “online learning,” or “campus sustainability.”

2. Do Some Background Reading

Dive into some books, articles, or reputable websites about your topic. This will help you understand what’s already known and what gaps might exist in the current research.

3. Narrow Down Your Focus

Based on your reading, choose a more specific aspect of your broad topic. For example, if you started with “student mental health,” you might narrow it down to “stress management techniques for college students.”

4. Identify Variables

What specific things do you want to measure or compare? In our stress management example, variables might include different relaxation techniques, stress levels, and academic performance.

5. Consider Your Research Design

Think about how you might go about studying this topic. Will you survey students? Conduct an experiment? Analyze existing data? Your research design will influence how you frame your question.

6. Draft Your Question

Using what you’ve learned about the characteristics and types of research questions, write a draft of your question. Don’t worry about getting it perfect – we’ll refine it later.

7. Get Feedback

Show your draft question to your professor, classmates, or a writing center tutor. They might spot issues you’ve missed or suggest improvements.

8. Refine and Finalize

Based on the feedback you receive, polish your question until it meets all the criteria for a good quantitative research question.

Common Mistakes to Avoid

Even the best researchers sometimes stumble when crafting research questions. Here are some common pitfalls to watch out for:

1. Being Too Broad

A question like “How does technology affect learning?” is way too broad for a single study. Narrow it down to something more specific, like “How does the use of educational apps impact math test scores among 10th-grade students?”

2. Using Vague Terms

Avoid words that are open to interpretation. Instead of “How do students feel about online classes?” try “What are the self-reported satisfaction levels of undergraduate students regarding synchronous online classes?”

3. Asking Yes/No Questions

Questions that can be answered with a simple yes or no don’t give you much to work with. Instead of “Do college students experience stress?” ask “What are the primary sources of academic stress reported by college students, and how do stress levels vary across different majors?”

4. Including Too Many Variables

While it’s tempting to try to cover everything, too many variables can make your study unwieldy. Focus on a manageable number of key variables.

5. Forgetting About Feasibility

Make sure you can actually answer your question with the resources and time you have available. A question requiring data from every university in the country might be exciting but probably isn’t feasible for a college research project.

6. Neglecting Ethical Considerations

Always consider the ethical implications of your research question. Avoid questions that could lead to harm or discomfort for participants.

Examples of Strong Quantitative Research Questions

Let’s look at some examples of well-crafted quantitative research questions across different fields of study. We’ll break down why each one works well.


“What is the relationship between daily social media use and self-reported anxiety levels among college students aged 18-22?”

Why it works: This question is specific (focuses on a particular age group and platform), measurable (daily use and anxiety levels can be quantified), and relevant to current issues in psychology.


“How does the implementation of a flipped classroom model affect test scores in introductory biology courses compared to traditional lecture-based instruction?”

Why it works: This question is comparative, measurable (test scores), and addresses a current trend in education (flipped classrooms).


“To what extent do employee satisfaction scores predict customer satisfaction ratings in retail businesses with over 500 employees?”

Why it works: This question is predictive, specific to a particular business size, and deals with measurable variables (satisfaction scores and ratings).

Health Sciences

“What is the correlation between weekly exercise duration and blood pressure levels among adults aged 40-60 with sedentary jobs?”

Why it works: This question looks at a relationship between specific variables (exercise and blood pressure), focuses on a particular population, and is relevant to public health concerns.

Environmental Science

“How does the implementation of a campus-wide recycling program affect the volume of waste sent to landfills from universities with over 10,000 students?”

Why it works: This question is causal, specific to a particular type of institution, and deals with a measurable outcome (waste volume).

Aligning Research Questions with Quantitative Methods

Once you’ve crafted your research question, you need to make sure it aligns with appropriate quantitative methods. Different types of questions lend themselves to different research designs and statistical analyses.

Surveys and Questionnaires

Best for: Descriptive and some relationship questions Example question: “What are the most common stress-coping mechanisms reported by first-year college students?” Analysis methods: Descriptive statistics, chi-square tests, correlation analyses


Best for: Causal and comparative questions Example question: “What is the effect of a 8-week mindfulness program on test anxiety levels among high school seniors compared to a control group?” Analysis methods: T-tests, ANOVA, ANCOVA

Correlational Studies

Best for: Relationship and some predictive questions Example question: “What is the relationship between hours spent studying and final exam scores in online vs. in-person classes?” Analysis methods: Correlation coefficients, regression analyses

Longitudinal Studies

Best for: Trend analysis and some causal questions Example question: “How do career aspirations change over the four years of college for students in STEM majors?” Analysis methods: Repeated measures ANOVA, growth curve modeling

Secondary Data Analysis

Best for: Descriptive, comparative, and some relationship questions using existing datasets Example question: “How does the graduation rate of first-generation college students compare to that of students with college-educated parents across public universities in the United States?” Analysis methods: Various, depending on the nature of the data (e.g., t-tests, regression, multilevel modeling)

Turning Your Research Question into Hypotheses

In quantitative research, your research question often leads to one or more hypotheses. A hypothesis is a testable prediction about the relationship between variables.

Steps to Create Hypotheses:

  1. Identify the variables in your research question
  2. Determine the expected relationship between these variables
  3. State this relationship in a clear, testable format


Research Question: “What is the relationship between hours of sleep per night and academic performance among college students?”

Hypothesis: “There is a positive correlation between average hours of sleep per night and GPA among college students.”

Research Question: “How does a 12-week exercise program affect depression scores in adults aged 30-50 compared to a control group?”


  1. “Participants in the exercise program will show a greater decrease in depression scores compared to the control group.”
  2. “The effect of the exercise program on depression scores will be moderated by initial fitness levels.”

Evaluating and Refining Your Research Questions

Even after you’ve crafted what you think is a solid research question, it’s important to step back and evaluate it critically. Here are some questions to ask yourself:

  1. Is my question clear and specific enough?
  2. Can I measure or quantify the variables involved?
  3. Is it feasible to answer this question with the resources and time I have?
  4. Does this question add something valuable to the existing knowledge in my field?
  5. Are there any ethical concerns with pursuing this question?
  6. Does my question align well with quantitative research methods?
  7. Can I form clear hypotheses based on this question?
  8. Is the scope of the question appropriate for my research project?

If you answer “no” to any of these, it might be time to refine your question. Don’t be discouraged – it’s normal to go through several iterations before landing on the perfect research question.

To wrap up, let’s address some frequently asked questions about research questions in quantitative research proposals:

  1. Q: How many research questions should I have in my proposal? A: It depends on the scope of your study, but typically 1-3 main research questions are sufficient for most college-level projects. It’s better to deeply explore a few questions than to superficially address many.
  2. Q: Can I change my research question once I’ve started my study? A: While it’s best to have a solid question before you begin, it’s not uncommon for questions to evolve slightly as you delve into your research. However, significant changes midway through a study can be problematic.
  3. Q: How do I know if my research question is too broad or too narrow? A: If your question could be the topic of an entire book, it’s probably too broad. If you can fully answer it in a paragraph, it might be too narrow. Aim for a question that can be thoroughly explored in the context of your research project.
  4. Q: Should my research question always be novel, or can I replicate previous studies? A: While novelty is valued in research, replication studies are also important in science. You could replicate a study in a different context or population, or extend previous findings in a new direction.
  5. Q: How do I handle it if my results don’t answer my research question? A: This is a normal part of the research process! Negative or inconclusive results are still valuable. Report your findings honestly and discuss potential reasons why your results might differ from expectations.
