A research question is 'a question that a research project sets out to answer'. Investigation will require data collection and analysis, and the methodology for this will vary widely. Good research questions seek to improve knowledge on an important topic, and are usually narrow and specific. To form a research question, one must determine what type of study will be conducted such as a qualitative, quantitative, or mixed study.
What is a hypothesis?
A research problem is a statement about an area of concern, a condition to be improved, a difficulty to be eliminated, or a troubling question that exists in scholarly literature, in theory, or in practice that points to the need for meaningful understanding and deliberate investigation. In some social science disciplines the research problem is typically posed in the form of a question.
A research problem does not state how to do something, offer a vague or broad proposition, or present a value question. The purpose of a problem statement is to:. In the social sciences, the research problem establishes the means by which you must answer the "So What? The "So What? Note that answering the "So What" question requires a commitment on your part to not only show that you have researched the material, but that you have thought about its significance. To survive the "So What" question, problem statements should possess the following attributes:.

Sources of Problems for Investigation. Identifying a problem to study can be challenging, not because there is a lack of issues that could be investigated, but due to pursuing a goal of formulating a socially relevant and researchable problem statement that is unique and does not simply duplicate the work of others.
To facilitate how you might select a problem from which to build a research study, consider these three broad sources of inspiration:. Deductions from Theory This relates to deductions made from social philosophy or generalizations embodied in life in society that the researcher is familiar with. These deductions from human behavior are then fitted within an empirical frame of reference through research.
From a theory, the research can formulate a research problem or hypothesis stating the expected findings in certain empirical situations. Interdisciplinary Perspectives Identifying a problem that forms the basis for a research study can come from academic movements and scholarship originating in disciplines outside of your primary area of study.
A review of pertinent literature should include examining research from related disciplines, which can expose you to new avenues of exploration and analysis. An interdisciplinary approach to selecting a research problem offers an opportunity to construct a more comprehensive understanding of a very complex issue than any single discipline might provide.
Interviewing Practitioners The identification of research problems about particular topics can arise from formal or informal discussions with practitioners who provide insight into new directions for future research and how to make research findings increasingly relevant to practice.
Discussions with experts in the field, such as, teachers, social workers, health care providers, etc. This approach also provides some practical knowledge which may help in the process of designing and conducting your study. Personal Experience Your everyday experiences can give rise to worthwhile problems for investigation.
This can be derived, for example, from deliberate observations of certain relationships for which there is no clear explanation or witnessing an event that appears harmful to a person or group or that is out of the ordinary. Relevant Literature The selection of a research problem can often be derived from an extensive and thorough review of pertinent research associated with your overall area of interest. This may reveal where gaps remain in our understanding of a topic.
Research may be conducted to: 1 fill such gaps in knowledge; 2 evaluate if the methodologies employed in prior studies can be adapted to solve other problems; or, 3 determine if a similar study could be conducted in a different subject area or applied to different study sample [i.
Also, authors frequently conclude their studies by noting implications for further research; this can also be a valuable source of problems to investigate. What Makes a Good Research Statement? A good problem statement begins by introducing the broad area in which your research is centered and then gradually leads the reader to the more narrow questions you are posing. The statement need not be lengthy but a good research problem should incorporate the following features:.
Compelling topic Simple curiosity is not a good enough reason to pursue a research study. The problem that you choose to explore must be important to you and to a larger community you share.
The problem chosen must be one that motivates you to address it. Supports multiple perspectives The problem most be phrased in a way that avoids dichotomies and instead supports the generation and exploration of multiple perspectives. A general rule of thumb is that a good research problem is one that would generate a variety of viewpoints from a composite audience made up of reasonable people. Choose research problems that can be supported by the resources available to you.
Not sure? A topic is something to read and obtain information about whereas a problem is something to solve or framed as a question that must be answered. Mistakes to Avoid. Beware of circular reasoning. For example, if you propose, "The problem in this community is that it has no hospital. This only leads to a research problem where:.

Importance of The purpose of a problem statement is to: Introduce the reader to the importance of the topic being studied. The reader is oriented to the significance of the study and the research questions or hypotheses to follow. Places the problem into a particular context that defines the parameters of what is to be investigated.

How to write a hypothesis
A hypothesis is a statement that introduces a research question and proposes an expected result. It is an integral part of the scientific method that forms the basis of scientific experiments. Therefore, you need to be careful and thorough when building your hypothesis. A minor flaw in the construction of your hypothesis could have an adverse effect on your experiment. A testable hypothesis is a hypothesis that can be proved or disproved as a result of experimentation. To devise and perform an experiment using the scientific method, you need to make sure that your hypothesis is testable. To be considered testable, some essential criteria must be met:.
Before formulating your research hypothesis, read about the topic of interest to you. From The research question flows from the topic that you are considering. The The examples below are final form hypotheses, which have been revised.

Null and Alternative Hypotheses
By Saul McLeod , updated August 10, A hypothesis plural hypotheses is a precise, testable statement of what the researcher s predict will be the outcome of the study. This usually involves proposing a possible relationship between two variables: the independent variable what the researcher changes and the dependent variable what the research measures. In research, there is a convention that the hypothesis is written in two forms, the null hypothesis, and the alternative hypothesis called the experimental hypothesis when the method of investigation is an experiment. The alternative hypothesis states that there is a relationship between the two variables being studied one variable has an effect on the other.
