Graphic of things to consider when thinking about statistical questions and guidelines to follow when defining statistical questions.

  • A statistical question is different from a non-statistical question
    When we ask a statistical question, we’re not just looking for a simple answer. We want to study and understand how things vary within a group. Statistical questions involve analyzing data to find patterns, relationships, and differences. Unlike non-statistical questions, which often have straightforward answers, statistical questions require data to provide meaningful insights.
  • Your statistical question is like a map for your study
    A well-designed statistical question acts as a roadmap for your study. It helps you plan what data you need to collect and guides you in analyzing and interpreting that data. By having a clear question, you can stay focused, organized, and achieve valuable results in your study.
  • A good statistical question makes sure your study matters
    Choosing a statistical question that is important not only to you but also to others makes your study significant. By addressing meaningful questions, you contribute to knowledge and provide insights that are helpful and interesting to a broader audience. This way, your study has a real impact.
  • A clear statistical question makes your results easy to understand
    When your statistical question is well-defined, it leads to clear and understandable results. By stating exactly what you want to find out, others can easily grasp and comprehend your findings. A clear question helps in effective communication and enhances the understanding of the implications of your research.
Guidelines for Defining Your Question
  1. Pick a topic you’re interested in (i.e., topic of interest)
    Select a topic that sparks your curiosity and aligns with your areas of interest. A genuine interest in the subject matter will fuel your motivation and engagement throughout the research process.
  2. Think up questions about your topic
    Generate a list of questions related to your chosen topic. Begin with broad questions and then gradually narrow them down to those that can be answered using data. This iterative process allows you to refine and focus your research question.
  3. Refine your questions
    Evaluate your questions to ensure they are specific, important, and relevant to your study. Consider seeking feedback from peers, mentors, or subject experts to gain different perspectives and improve the clarity and quality of your questions.

Key Attributes that Make a Statistical Question Effective and Suitable for Research
  • Addresses variation: A good statistical question focuses on understanding the variation within a population or between different groups. It seeks to explore patterns, differences, or relationships in data.
  • Involves data: A statistical question requires the collection and analysis of data to find meaningful answers. It goes beyond subjective opinions or personal anecdotes and relies on empirical evidence.
  • Specific and well-defined: A good statistical question is clear, concise, and well-defined. It leaves no room for ambiguity or confusion and provides a precise direction for the research study.
  • Relevant and meaningful: The question should be relevant and have significance in the bigger picture. It should address a problem, fill a gap in knowledge, or help us understand something better.
  • Answerable with data: A good statistical question can be answered by collecting and analyzing data. It’s possible to get the necessary information and draw valid conclusions. If you can’t collect the needed data, you may need to change your question.
  • Focused on a population: The question specifies the group of people or things being studied. It narrows down the focus to make sure the findings are relevant to that specific group.
  • Identifies the variable of interest: A good statistical question identifies the specific thing or characteristic being studied. It tells us what aspect of the group we want to measure, compare, or explore.
  • Considers units of measurement: If the thing being studied can be measured with numbers, the question should say how that will be done. It tells us what units or scales will be used to measure it.
  • Considers time frame and scope: The question thinks about the time period and place of the study. This helps set boundaries and gives context to the research.
  • Unbiased and fair: A good statistical question doesn’t favor one answer over another. It allows for fair and impartial analysis. It considers all possibilities and perspectives.

By incorporating these elements into the development of a statistical question, researchers can ensure that their study is focused, meaningful, and capable of generating valuable insights from data analysis.


How to Avoid Mistakes and Make the Best Research Questions for Your Statistical Investigation
  • No fuzzy questions: It’s important to avoid fuzzy or unclear questions that make it difficult to gather the necessary data or decide how to analyze it. Make sure your research question is detailed and provides a clear direction for your study.
    Fuzzy question: “What do students think about the school?”
    Non-fuzzy question: “What is the overall satisfaction level of 10th-grade students regarding the school’s extracurricular activities?”
    In this revised version, the question specifies the target group (10th-grade students), the aspect of the school (extracurricular activities), and the information sought (overall satisfaction level). This makes the question clearer and provides a specific focus for data collection and analysis.
  • Do not forget about variation: A good statistical question looks closely at how things are different, related, or connected within a group of people or things. It wants to find patterns or differences that can be discovered by studying data. If researchers don’t pay attention to these differences, they might ask questions that are too general and miss important details. This can make the results unfair or incomplete, making the study less reliable and helpful. 
    • Question without variation: “What is the temperature?” 
    • Question with variation: “How does the temperature vary throughout the year in different regions of the world?” 
  • Think of many questions: Do not settle for the first question that comes to mind. Think of multiple questions related to your topic and explore various angles. By considering multiple perspectives, you can select the most promising research question for your investigation. 
  • Ensure fairness (avoid bias): Try to avoid asking questions that could make you prefer a certain answer or viewpoint. It’s important to stay fair and objective in your research question so you can consider all the different possibilities. This helps you analyze the data in a complete and unbiased way without any favoritism.
    Biased question: “Do you agree that smartphones are ruining the younger generation?”
    Fair question: “What are the effects of smartphone usage on the younger generation?”
    The original question seems to have a biased view against smartphones and assumes they have a bad influence on young people. It may influence people to answer in a specific way. The revised question, on the other hand, removes the bias by asking about the effects of smartphone usage without assuming they are negative. This lets us explore both the good and bad effects and consider different opinions. We can then look at various outcomes, like how smartphones affect social interactions, school performance, mental health, and overall well-being. This approach allows us to have a fair analysis without any preconceived ideas.
