Writing Research Questions and Hypotheses 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.

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?

Study objectives define the specific aims of the study and should be clearly stated in the introduction of the research protocol.

It is predictive in nature and typically used when significant knowledge already exists on the subject which allows the prediction to be made. Data is then collected, analyzed, and used to support or negate the hypothesis, arriving at a definite conclusion at the end of the research.

It is always written as a statement and should be developed before any data is collected. A complete hypothesis should include: Commonly used in quantitative research, but not qualitative research which often seeks answers to open-ended questions.
