Research questions are essential for defining the nature and scope of research. By selecting questions, and paying attention to their wording, it is possible to determine what is to be studied and, to some extent, how it will be studied. The way a particular research question is worded can have a significant influence on how much and what type of research activity will be required.
Conventional wisdom suggests that research should be guided by one or more hypotheses. According to this view, in order to get started on a research project the researcher should: first, select a research problem; second, state one or more hypotheses to be tested; and, third, measure and correlate the variables related to the concepts in the hypotheses. However, this procedure is only relevant when quantitative data are used with Deductive logic. While there is a role for hypotheses in this kind of research, they neither provide the foundation for a research design nor are they very useful for defining the focus and direction of a research project. In fact, the ritual of formulating and testing hypotheses can lead to unnecessary and unhelpful rigidities in the way in which research is conducted. In some kinds of research, it is impossible or unnecessary to set out with hypotheses. A much more useful procedure is to establish one or more research questions.
A Neglected Component of Social Research
Until fairly recently, few textbooks on research methods gave attention to the formulation of research questions, and some ignored this vital part of the research process entirely. Exceptions can be found. See, for example: Hedrick et al. (1993); Miles and Huberman (1994); Blaxter et al. (2002); Mason (2002, 2017); Yin (2003a); Maxwell (2005); Marshall and Rossman (2006); Neuman (2006, 2014); Flick (2006, 2007, 2014, 2015); Green (2008); Punch (2014); Creswell (2017).
It is interesting to note that these books are either concerned with qualitative research methods or include a significant discussion of them.
Flick argued for the importance of research questions in qualitative research.
Experience from my own research and even more from supervising and consulting other people in their research has shown how decisive it is for the success of a project to have a clear and explicitly formulated research question. (Flick 2007: 22)
[A] first and central step, and one which essentially determines success in qualitative research, but tends to be ignored in most presentations of methods, is how to formulate the research question(s). (Flick 2006: 105)
Creswell (2017) argued that, in a qualitative study, research questions are central, not objectives (goals for research) or hypotheses (predictions involving variables and statistical tests). We concur wholeheartedly with Flick’s statements above and would argue that what he and Creswell say about qualitative research applies to all social research.
Mason (2002) set her discussion of research questions in the context of intellectual puzzles that demand some kind of explanation. These puzzles take a variety of forms, depending on the ontological and epistemological positions adopted by the theoretical and intellectual traditions from within which they emerge. Intellectual puzzles then lead to research questions that Mason regarded as forming the backbone of a research design, and as having much greater significance than hypotheses or propositions, particularly in qualitative research. For her, research questions should be clearly formulated (whether or not you intend to modify them or add to them later), intellectually worthwhile, and researchable (both in terms of your epistemological position, and in practical terms), because it is through them that you will be connecting what it is that you wish to research with how you are going to go about researching it. They are the vehicles which you will rely upon to move you from your broad research interest to your specific research focus and project, and therefore their importance cannot be overstated. Research questions, then, are those questions to which you as researcher really want to know the answers, and in that sense they are the formal expression of your intellectual puzzle (Mason 2002: 19–20).
These examples should be sufficient to reinforce our argument about the pivotal role played by research questions in social research.
