5 Research Questions and Purposes 5.1 Chapter Summary • All social research is built on the foundation of research questions. • Research questions define the nature and scope of a study. • Research questions can be grouped into three main types, 'what', 'why' and 'how' questions. « The three types of questions form a sequence for the research process: 'what' questions, followed by 'why' questions, followed by 'how' questions. • The importance of answering 'what' questions should not be underestimated. • The developmental nature of a research design should not be used as an excuse to avoid the effort required to formulate appropriate research questions. • While the process of developing a set of research questions can be the most challenging part of any research project, techniques are available to assist the process. • Research questions are what the research is designed to answer, not the questions asked of respondents or participants. • The aim of the literature review is to indicate what the state of knowledge is with respect to each research question or group of questions. • Hypotheses are best guesses at answering 'why' and, possibly, 'how' questions. • If required, hypotheses should be derived from the literature review, particularly from theory or research results. Sometimes a new theory may have to be constructed. • In some research, working hypotheses may emerge, and be tested, in the course of the data collection and/or generation and analysis. ' As an aid to the conception, clarification and classification of research questions, it is also useful to think about social research in terms of its purposes. Social research can pursue eight major purposes: explore, describe, understand, t "-P'<"", predict, change, evaluate and assess impacts. ' cT^ researc'1 PurPoses require 'what' questions. Understand and explain, " . to a lesser extent, evaluate and assess impacts, require 'why' questions. My change requires 'how' questions. 68 Designing Social Research Research purposes are not a list of the activities the researcher is going to carry out; they can be either the analytical or the practical goals of a project. 5.2 Introduction Formulating research questions is the most critical component of any research design. It is only through the use of such questions that a research problem becomes researchable, that choices about the focus and direction of research can be made, that its boundaries can be clearly delimited, that manageability can be achieved and that a successful outcome can be anticipated. Establishing research questions also makes it possible to select logics of inquiry and methods of data collection and/or generation and analysis with confidence. In other words, a research project is built on the foundation of its research questions. However, getting these questions clear and precise requires considerable thought and sometimes some preliminary investigation. This chapter discusses: • three main types of research questions; • the functions of research questions; • how to develop and refine research questions; • the relationship between research questions and hypotheses, and the functions of the latter; and ■ how research questions can provide a guide and framework for the review of j the literature. As a way of elaborating research questions, consideration is also given to the! research purposes behind the questions. Hence, there is a discussion of: • the nature and range of research purposes that can be pursued; and • the relationship between research purposes and research questions (see Figure 5.1), 5.3 Research Questions 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 deter-l mine what is to be studied and, to some extent, how it will be studied. The way j 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 i quantitative data are used with Deductive logic. While there is a role for hypotft eses in this kind of research, they neither provide the foundation for a resear j research Questions and Purposes 69 Political economic Social Technological Environmental Legal Academic Basic research Applied research Figure 5.1 focusing a research design determines its scope Explore Describe Explain Understand Predict Change Evaluate assess impacts *"* kindsoft«Ä Can to m"ch more use" it Vm^le or unnecessaryto?,'* COnd^d. 1 procedure ,s to -wish oJTZZZThyporhes- '»earcn questions. Until fairly recently, few textbooks on research methods gave attention to the ormulation 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); and Huberman (1994); Blaxter et al. (2002); Mason (2002, 2017); Yin bT? a>; Maxwell (2005); Marshall and Rossman (2006); Neuman (2006,2014); «* (2006, 2007. 2014, 2015); Green (2008); Punch (2014); Creswell (2017). ANe8,e«,dCor„w„mtofSoaj,Research 70 Designing Social Research 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) J i firsr and central step, and one which essentially determines success in qualita-rch, but tends to be ignored in most presentations ' m tive rcsearcn, oui iohh — .„ 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 all social research.

'Why' questions ask for either the causes of, or the reasons for, the existence of characteristics or regularities in a particular phenomenon. They are directed towards understanding or explaining the relationships between events, or within social activities and social processes. For example: • Why do people think and act this way? • Why did these patterns come to be this way? • Why do the individual characteristics, or social processes, change or remain stable? • Why does this activity have these particular consequences? 'How' questions are concerned with bringing about change, with practical outcomes and intervention. For example: • How can these characteristics, social processes or regularities be changed? • How can they be made to stop changing, or to slow down or speed up their rate of change? These three types of research questions form a sequence: 'what' questions normally precede 'why' questions, and 'why' questions normally precede 'how' questions. We need to know what is going on before we can explain it, and we need to know why something happens the way it does before we can be confident about intervening to change it. However, most research projects will include only one or two types of research questions, most commonly 'what' and 'why' questions. Some research may not proceed beyond one or more 'what' questions. While there may be a strong desire to include 'why' and possibly 'how' questions in a research project, the significance of producing good answers to 'what' questions should not be underestimated. In some fields, and on some topics, little research may have been undertaken anywhere, or recently, or in the context of interest. Before 'why' questions can be tackled, a good description of what is going on is needed. This may be an opportunity to make an important contribution to knowledge. In addition, some social scientists have argued that good description ■s all that is needed for an adequate understanding of many topics. Certainly, in comparative studies, description is the fundamental task. In short, good description is a vital part of social research. A number of writers have proposed more than three types of research questions. Yin (2003a), for example, discussed seven types: 'who', 'what', 'where how many', 'how much 'h' f XVm types: 'who'> 'where', 5°'. ^t;^! I/? Why' ,H™' he *« acknowledge tha : <***<>n.

Hedrick et al. (1993: 23-32) identified four types of research questions that are relevant to applied research: descriptive, normative, correlative and impact. Marshall and Rossman (2006) have classified research questions as theoretical, as focusing on particular populations and as being site-specific. However, these categories relate to the context in which they are examined and not to the purpose behind the question. We restrict our discussion to the three types of research questions, 'what', 'why' and 'how', and believe that the discipline of reducing all questions to these three types helps to make the links between research questions and research purposes clear. Examples of Research Questions Let us return to the four research topics discussed in chapter 2 and examine some possible research questions for each one. Environmental Worldviews and Behaviour among Students and Residents 1. To what extent do students and residents hold different environmental worldviews? 2. To what extent is environmentally responsible behaviour practised? 3. To what extent, and in what ways, is environmental behaviour related to environmental worldviews? As these are all 'what' questions, the study will have only descriptive purposes. It J seeks to describe the distributions of environmental worldviews and behaviour in ] these populations, and the pattern of the relationship between them. Age and Environmentalism: A Test of Competing Hypotheses 1. To what extent is age related to environmental worldviews and environ- j mental behaviour? 2. If there are relationships, what are their forms? 3. Why do these relationships exist? These are straightforward research questions, two 'what' questions followed b)f i a 'why' question. The study wishes to establish the nature of these relationship* I and then to explain them. Gender Differences in Environmentalism: Towards an Explanation 1. To what extent do women hold more favourable environmental attitudes than men? 2. To what extent are women more willing than men to engage in environrnfl1' tally responsible behaviour? 3. If there are gender differences in environmentalism, why do they exist? 4 Research Questions and Purposes 73 Again, this is a combination of 'what' and 'why' questions seeking descriptions of relationships and explanations for them. Motivation for Environmentally Responsible Behaviour: The Case of Environmental Activists 1. In what types and intensity of behaviour do environmentally responsible individuals engage? 2. Why do these people act responsibly towards the environment? 3. Why do some of these people manage to sustain this behaviour? 4. How can the incidence of this type of behaviour be increased? Now we come to a combination of all three types of research questions. Research on this topic seeks to describe environmentally responsible behaviour, and then to explain why people engage in and manage to sustain that behaviour. Then it is concerned with how to get more people to behave this way. It would be unlikely that a study of this kind could do anything more than point in the direction of possible answers to this last question, using the answers to questions 2 and 3. But it could also suggest ideas for further research to explore ways to change this behaviour. (See Appendix II for examples of different and more complex sets of research questions.) Developing and Refining Research Questions The process of translating a research problem into a set of research questions can be challenging. This is particularly the case when a researcher initiates the project, as in much academic and postgraduate research in the social sciences. However, the problem still exists in research that is commissioned by someone else for problem-solving or policy-related purposes. Organizations or groups that commission research are very often vague about what they want done, and usually need some assistance to clarify the research questions. It is very rare to commence a project with clearly formulated research questions already provided. This might occur where a researcher has joined a research programme in which the research questions have already been established, or if a researcher is taking up questions posed in previous research. However, it is much more common in the social sciences to approach a topic or field in which previous research is limited or has used an approach different from the one the researcher "insiders to be appropriate. All researchers have to devise their own way of developing research questions. ^ hat is offered here is a process that has been found to work successfully with many Postgraduate students. Note that every step may not be required in every project. Creswell (2003, 2017), Maxwell (2005) and Punch (2016) offer other techniques. '■ Write down every question you can think of that relates to the research V lent The wj|| include all kinds of questions; some will be seeking t'Ptions, some explanations, some will be concerned with action, and so Designing Social Research on. There is no need to try to achieve any order or consistency in the list; simply record the questions as they arise. One question will usually stimulate other questions; they should all be recorded. This activity may produce a long list. The purpose is to try to expose all the ideas that you have on the research problem, particularly those that may be taken for granted and which later you wish you had been fully aware of at the design stage. No question should be censored, even if it may seem to be marginal, outrageous or impractical. 2. Review the list of questions Once you are satisfied that you have pretty well exhausted all the ideas you have on the research problem, you should review the list. There are a number of strategies for doing this. • Group the questions under similar themes or topics, if such exist in your list. This is likely to reveal overlaps between questions that will make it possible to eliminate some and to consolidate others. Part of this consolidation can be achieved by developing a single, general or abstract question that summarizes a group of more specific ones. • Set aside questions that seem to be marginal to the research problem, that are too outrageous, or that seem to take you in directions that may be too difficult or too demanding. You can always review these questions later if you decide to change the direction of the research. 3. Separate 'what', 'why' and 'bow' questions Within each group of questions, J begin to identify those that appear to be concerned with description, explanation/1 understanding and change. Of course, some studies may be concerned ultimately I with only one type of question; for example, one or more 'what' questions, or just I a 'why' question. The wording of 'what', 'why' and 'how' questions requires very careful consid- j eration, as the way a question is stated can initially be deceptive: 'what' and 'wh™ questions can begin with 'How', and 'how' questions can begin with 'What'. I For example: 'How are environmental behaviour and environmental worldview* related?* This needs be transposed into a descriptive question, such as: 'What is J the relationship between environmental behaviour and environmental world- j view?', or 'To what extent, and in what ways, is environmental behaviour related j to environmental worldview?' The question, 'How do some people manage tol behave in an environmentally responsible way?' needs to be transposed into an explanatory question: 'Why do these people act responsibly towards the J environment?' The question, 'What can be done to increase the incidence ot environmentally responsible behaviour?' needs to be transposed into an interven- i tion question: 'How can the incidence of environmentally responsible behaviour] be increased?' It is useful to try to identify the purpose the question is serving] (description, explanation/understanding or change) and then get the wording <*§ the question consistent with this. Make sure that each question is worded as clearly and as simply as possible awl that each one can be identified unambiguously as a 'what', 'why' or 'how' qu*| tion. Complex questions may need to be broken down into a series of question*.] For example, the question, 'What is the incidence of student plagiarism? wouWI Research Questions and Purposes be better broken down into at least two questions: 'What has been the extent of detected student plagiarism over the past five years?' and 'In what types of plagiarism have students engaged?' (See Appendix II.) 4. Expose assumptions Check each question to see what it assumes. Many questions, particularly 'why' questions, presuppose other questions. It is important to expose the 'what' question that must be answered before a 'why' question can be asked or, perhaps, even formulated. 'How' questions may presuppose both 'what' and, particularly, 'why' questions. A research project may need to examine all three types of questions. Rather than reducing the number of questions on the list, this part of the process may add further questions. 5. Examine the scope of the questions Now is the time to get practical and ask yourself how many groups of questions, and questions within groups, can be tackled in the study. A judgement has to be made about what is going to be manageable within the time and resources available. There is an inevitable tendency to try to do too much; the questions for the topic on student plagiarism are a good example (see Appendix II). Therefore, it is advisable at this stage to reduce the project to what may appear to be an extremely limited or even narrow set of questions. Such innocent-looking questions usually have other questions implicit within their intentions and scope. 6. Separate major and subsidiary questions Once the list of questions has been reduced to what appears to be a manageable set, further work can be done on them. It may be useful to separate the questions into two broad categories, major questions and subsidiary questions.1 Major research questions are those that will form the core of the research project, the key questions that are to be answered. They may also be stated more abstractly than some of the other questions. Most research projects are likely to have a combination of major questions: 'what' questions and a 'why' question, or a set of 'what', 'why' and 'how' questions. About five or six major research questions is probably more than enough for any project, but only one may be necessary to address the research problem. Subsidiary questions will include those that deal with background information or issues that are presupposed by one or more major questions that, while being necessary, are not absolutely central to the project. Here is an example of a set of major and subsidiary questions. Major research question To what extent is environmentally responsible behaviour practised? Subsidiary- research questions ^ To what extent are household waste products recycled? , what extent is buying environmentally damaging products avoided? 0 W'hat extent is public transport and cycling used in preference to private motor vehicles? Designing Social Research In this example, the subsidiary questions can be used to specify categories of environmental behaviour and thus focus the study. 7. Is each question necessary? As your set of questions begins to take shape, you need to subject them to critical scrutiny by asking of each question: 'Why am I asking this question?' 'Is it related to the research problem?' 'Why do I want to know this?' 'What will I do with the results from it?' 'How does it relate to other questions?' 'Is it researchable?' 'Can ] manage all these questions?' This process needs to be taken very seriously and not glossed over quickly. It is very easy to include questions because 'that would be interesting to explore', or 'I would really like to know about that.' This critical examination needs to be ruthless. A common mistake in drafting research questions is to confuse them with questions used to elicit information from respondents or participants, for example, interview questions, or questions that would go into a questionnaire. Research questions are what you want the study to answer. Questions you ask respondents or participants can provide the basis for answering research questions, but their style and scope are very different. Many postgraduate students seem to have a desire to do the definitive piece of research on their topic. This is not only an unrealistic expectation for a fully research-based PhD; it is impossible in research for any other kind of postgraduate degree. The problem is most acute for students undertaking a coursework (taught) master's degree in which there is a minor thesis/dissertation/project com- j ponent. Because of its limited duration, such a research project is very difficult to design. In short, the number and nature of the questions selected has to reflect the available time and resources. This is the stage at which the scope of the project is J determined, and bad decisions can produce serious problems later. It is important to recognize that while it is highly desirable to produce well-formulated research questions as part of an integrated research proposal Ota design, this may not always be possible without some preliminary research being! undertaken. In addition, what is discovered in the process of undertaking the J research is likely to require a review of the research questions from time to time. No research design can completely anticipate how a research project will evolve, j It may turn out that some research questions cannot be answered because it is not , possible to obtain the necessary data. What the researcher assumed or was led tod believe about the availability of, or access to, the necessary data may turn out ten be wrong. Consequently, the design may require some revision, and part of this:J may involve changes to research questions, or their elimination or replacement. Hence, while it is necessary to be as clear as possible about the scope and direc- j tion of the research at the beginning, what the researcher learns in the course of undertaking the research may necessitate some changes. This is just the nature! of research in any discipline. Research projects differ in the extent to which it is possible to produce precise research questions. This is certainly true of exploratory research, the aim an observed pattern can also be used to predict another pattern. For example* I if an explanation has been constructed to explain why the suicide rate is low in a country in which a particular religion is predominant, and if religion has been shown in a deductive argument to be related to suicide rates (as DurkfieiMJ claimed to have established), then it is possible to predict that other countries or. a similar religious composition will have similar suicide rates (sec Blaikie 100':\ 72-4 for a discussion of Durkheim's theory of suicide). Research Questions and Purposes Writers who have advocated the use of Retroductive logic (e.g. Bhaskar 1979) have argued that prediction is only possible in closed systems, perhaps only under experimental conditions. As social scientists have to work in open systems, it follows that prediction is not possible in the social sciences. Change Research that is concerned with change endeavours to intervene in a social world to bring about partial or major changes, either in conjunction with the research itself, or as a consequence of research findings. Change can only be achieved with confidence if the actions taken are based on those that a well-established explanation or understanding would suggest. However, the process of intervention itself can be used as a learning process. Knowledge of a phenomenon can be developed in a trial and error process, as intervention is conducted in stages. What is learnt from one stage can be used to decide what action to take in the next stage. Nevertheless, this kind of intervention needs to be distinguished from intervention that tries to change some aspect of the social world. The 'action research' tradition has the joint purposes of increasing knowledge and changing some aspect of the world at the same time. It differs from more conventional research in that the researcher may take the role of facilitator or resource person who helps a group of people change their own situation from the inside, rather than the researcher adopting the role of outside expert who tries to bring about change by "external' intervention. This type of research is usually referred to as 'participatory action research' (Whyte 1991; Wadsworth 1997a, 1997b, 2010). In some paradigms (e.g. critical theory and feminism) it is argued that change is the fundamental purpose of social science; all other purposes must serve that of the emancipation of oppressed groups. As such, while the purpose of change may be regarded by many as an add-on stage in research, it has been regarded by some as being either the only way to generate scientific knowledge, or the only legitimate form of social science. Intervention research can also be done 'top down', thus serving the needs of the powerful, or 'bottom up' by serving the needs of the powerless. Hence, it may be viewed loosely as either 'conservative' or 'radical'. Evaluate Evaluation research seeks to examine the consequences of the adoption of particular courses of action. It sets out to determine whether a policy or programme has been effective in achieving certain policy or programme goals. Evaluation research compares 'what is" with 'what should be' (Weiss 1972: 6). Hie purpose of evaluation research is to measure the effects of a program against •he goals it set out to accomplish as a means of contributing to subsequent decision making about the program and improving future programming' (Weiss "72:4). Two types of evaluation research are commonly discussed: formative evaluation, in which built-in monitoring or continuous feedback is used during the 'mplementation ot a policy as a basis for helping to improve it; and summative nation, which is conducted after a policy has been implemented to establish soverall effectiveness in achieving the original goals. Designing Socio/ Research Pawson and Tilley (1997) have identified four main perspectives on evaluation research: the experimental (Campbell and Stanley 1963a, 1963b; Cook and Campbell 1979); the pragmatic (Weiss 1972, 1976; Weiss and Bucuvalas 1980); the naturalistic (Lincoln and Cuba 1985); and the pluralist (Cronbach 1963, 1982; Rossi and Freeman 1985). The first on the scene in the 1960s, the experimental perspective, used classical or quasi-experimental procedures to try to establish whether change is the result of the planned intervention. Pawson and Tilley have added a fifth perspective, realistic evaluation, based on scientific realism (see chapter 6, 'Critical Realism'), for which they claim superiority over the other perspectives. More recently, Pawson (2006) has taken this approach further in his argument for evidence-based policy.2 Commonly used tools in both evaluation research and impact assessment are needs analysis and cost-benefit analysis. However, it is because of the deficiencies in cost-benefit analysis, due to its narrow economic focus, that the development of both social impact assessment and environmental impact assessment has occurred. Assess impacts Impact assessment (IA) has been defined as 'the process of identifying the future consequences of a current or proposed action" (Becker 1997: 2). In the case of social impact assessment (SIA), these consequences are related to 'individuals, organizations, institutions and society as a whole'' (Becker 1997: 123). Following the definition of SIA in the United States by the Inter-organizational Committee on Guidelines and Principles (1994), Burdge and Vanclay (1995) have included cultural as well as social impacts. Social impacts j are the consequences of any public and private actions that alter the way in which people live, work, play, relate to one another, organise to meet their needs, and generally cope as members of :j society. Cultural impacts involve changes to norms, values, and beliefs of individuals that guide and rationalise their cognition of themselves and their society. (Burdge and Van.lav 1995: 32) SIA can be concerned with assessing or predicting the demographic, socioeconomic, institutional, community and psychological impacts of resource! development and large-scale construction projects, as well as social or economic policies and programmes. The tasks of SIAs are to: • assess and predict potential impacts; • mitigate and monitor these impacts; and • audit and analyse the impacts of past actions. In many ways, SIA has grown out of the related and increasingly significant field of environmental impact assessment (EIA). While the latter's primary concern is with the natural and biophysical impacts of major physical projects, it is now generally accepted that EIA and SIA are complementary and that the latter must accompany the former. Research Questions and Purposes Research Purposes and Questions Explore Describe Understand Explain Predict Change Evaluate Assess impacts What might be happening? What people are involved? In what way? What is happening? What people are involved? In what way? Why is it happening? Why is it happening? What is likely to happen? How can it be made to be different? What has happened? Why did it happen? What have been, or are likely to be, its individual, social and environmental consequences? Why have these consequences occurred? The purposes of understand and explain,'' and, to a lesser extent, evaluate and assess impacts, are the only ones that require 'why-type' questions. Change is the only purpose that requires 'how-type' questions. All the other purposes have questions beginning with 'what', or their questions can be transposed into this form. They are, therefore, either descriptive in nature, or involve comparisons between situations in the present, between a present and a past situation, or between a present situation and a desired future. To avoid the confusion that can result from other question wording - for example, pursuing description or explanation with questions that commence with 'how' - this three-category classification of questions should be followed. 5.5 Conclusion The central role of research questions should now be clear. They are essential for defining the nature and scope of a study, and for determining what is to be studied, as well as, to a degree, how it will be studied. All social research can be conducted using just three types of research questions: 'what', 'why' and 'how' questions. 'What' questions seek a description, why' questions seek either an explanation or some form of understanding, and how' questions are concerned with change; in short, 'What is going on?', 'Why has it happened?' and 'How could it be different?' It can be tempting to ask questions that start with some word other than 'what', why and 'how'; for example, 'who', 'where', 'when' or 'how many'. However, *f the purpose of the question is description, then it is not difficult to transcribe es*' examples into a 'what-type' question. Some questions that begin with 'how' 86 Designing Social Research may in fact be 'what' or 'why' questions. For example, 'How did it happen?' may be asking 'What happened?' or 'Why did it happen?' Therefore, just what form of question is being asked, and how it should be worded, can be clarified by thinking about the purpose of the question, along with the type of knowledge a researcher wants to produce. To the four main purposes - description, explanation, understanding and change - can be added exploration, prediction, evaluation and impact assessment. However, these additional purposes can all be expressed as 'what' questions: 'What is happening?; 'What is likely to happen?'; 'To what extent did the programme achieve its goals?'; and 'What are the implications or consequences?' 5.6 Further Reading Andrews, R.
