How to Develop a Good Research Question: Researchers should begin by identifying a broader subject of interest that lends itself to investigation. For example, a researcher may be interested in childhood obesity. The next step is to do preliminary research on the general topic to find out what research has already been done and what literature already exists.
How much research has been done on childhood obesity? What types of studies? Is there a unique area that yet to be investigated or is there a particular question that may be worth replicating? The following video may be helpful in learning how to choose appropriate keywords and search online databases: For example, a researcher may want to consider the factors that are contributing to childhood obesity or the success rate of intervention programs.
Create a list of potential questions for consideration and choose one that interests you and provides an opportunity for exploration. Finally, evaluate the question by using the following list of guidelines: Is the research question one that is of interest to the researcher and potentially to others? Is it a new issue or problem that needs to be solved or is it attempting to shed light on previously researched topic. Is the research question researchable? Consider the available time frame and the required resources.
Is the methodology to conduct the research feasible? Is the research question measureable and will the process produce data that can be supported or contradicted? Is the research question too broad or too narrow? This is too narrow because it can be answered with a simple statistic.
Questions that can be answered with a "yes" or a "no" should also typically be avoided. How does the education level of the parents impact childhood obesity rates in Pheonix, AZ?
This question demonstrates the correct amount of specificity and the results would provide the opportunity for an argument to be formed. Unfocused and too broad: What are the effects of childhood obesity in the United States? This question is so broad that research methodology would be very difficult and the question is too broad to be discussed in a typical research paper. How does childhood obesity correlate with academic performance in elementary school children?
This question has a very clear focus for which data can be collected, analyzed, and discussed. How much time do young children spend doing physical activity per day? This question may allow the researcher to collect data but does not lend itself to collecting data that can be used to create a valid argument because the data is just factual information. What is the relationship between physical activity levels and childhood obesity? This is a more subjective question that may lead to the formation of an argument based on the results and analysis of the data.
How are school systems addressing childhood obesity? Once you have chosen your research topic or subject, you will need to decide how you will approach the research process — by formulating a hypothesis or developing a research question. This can be determined by starting with the following questions.
Is there a significant body of knowledge already available about your subject that allows you to make a prediction about the results of your study before you begin? If so, you will be using a hypothesis. Or is your research more exploratory and investigative in nature and will require that you collect data and analyze results before drawing any conclusions? If this describes your research topic, you will be developing a research question. Understanding this difference and choosing the correct approach will drive the rest of your research project.
The following sections further describe research questions and hypotheses and provide examples of each. The following video, Hypotheses vs. Research Questions, discusses how to choose whether to use a hypothesis or a question when creating a research project. It provides a definitions, a comparison of the two, and examples of each. Writing Good Quantitative Research Questions — This web resources describes the 3 main types of research questions and provides examples of each.
Quantitative Research Questions — Following is a resources that discusses the various types of research questions as well as the difference between a research question and a research hypothesis. Planning My Research Question or Hypothesis — This resources contains a link to a PowerPoint presentation and a series of tutorials that contain examples and tips for writing research questions and hypotheses.
Developing Hypothesis and Research Questions — The presentation below offers an indepth look at hypotheses and research questions and how they relate to the overall project and drive the research process.

Research Questions and Hypotheses The purpose of this module is to discuss research questions and research hypotheses and to provide definitions, comparisons and examples of both.
Define research question and research hypothesis. Explain the difference between a research question and a research hypothesis and describe the appropriate use of each. Describe the purpose of each and understand the importance of a well-developed question or hypothesis. Provide examples of research questions and research hypotheses.
Used to analyze and investigate a topic. It is written as a question and is inquisitive in nature. A properly written question will be clear and concise. It should contain the topic being studied purpose , the variable s , and the population. Three main types of questions:
In this article, we discuss important considerations in the development of a research question and hypothesis and in defining objectives for research. By the end of this article, the reader will be able to appreciate the significance of constructing a good research question and developing hypotheses.
RESEARCH QUESTIONS Nature of Hypothesis The hypothesis is a clear statement of what is intended to be investigated. It should be specified before research is conducted and openly stated in reporting the results. This allows to: Identify the research objectives.
The following video, Hypotheses vs. Research Questions, discusses how to choose whether to use a hypothesis or a question when creating a research project. It provides a definitions, a comparison of the two, and examples of each. CHAPTER SEVEN Research Questions and Hypotheses I nvestigators place signposts to carry the reader through a plan for a study. The first signpost is the purpose statement, which establishes the.
