RESEARCH METHODS
THE BASICS
Research Methods: The Basics is an accessible, user-friendly introduction
to the different aspects of research theory, methods and practice.
Structured in two parts, the first covering the nature of knowledge
and the reasons for research, and the second the specific methods
used to carry out effective research, this book covers:
structuring and planning a research project
the ethical issues involved in research
different types of data and how they are measured
collecting and analysing data in order to draw sound conclusions
devising a research proposal and writing up the research.
Complete with a glossary of key terms and guides to further reading, this
book is an essential text for anyone coming to research for the first
time, and is widely relevant across the social sciences and humanities.

INTRODUCTION
Research Methods are the tools and techniques for doing research.
Research is a term used liberally for any kind of investigation that
is intended to uncover interesting or new facts. As with all activities,
the rigour with which this activity is carried out will be reflected in
the quality of the results. This book presents a basic review of the
nature of research and the methods which are used to undertake a
variety of investigations relevant to a wide range of subjects, such as
the natural sciences, social science, social anthropology, psychology,
politics, leisure studies and sport, hospitality, healthcare and nursing
studies, the environment, business, education and the humanities.
Just about every university course includes an element of research
that students must carry out independently, in the form of projects,
dissertations and theses, and the more advanced the degree, the
greater the research content. In the workplace there is frequently
a need to do research in order to develop or improve the business
or service, while some types of businesses rely on doing research
projects for their very existence.
Research methods are a range of tools that are used for different
types of enquiry, just as a variety of tools are used for doing differ-
ent practical jobs, for example, a pick for breaking up the ground or
a rake for clearing leaves. In all cases, it is necessary to know what
the correct tools are for doing the job, and how to use them to best
effect. This book provides you with the basic information about the
tools used in research, the situations in which they are applied and
indicates briefly how they are used by giving practical examples.
INTRODUCTION2
I have also included chapters that describe the theoretical background
to research and the ways of thinking that lead to the different ways
of carrying out investigations and coming to conclusions. Therefore,
the book is divided into two basic parts. Part I consists of Chapters 1–5
and provides an introduction to research theory and general practice.
Part II contains Chapters 6–11 and explains the main research meth-
ods used for collecting and analysing data and gives advice on the
practical issues of presenting your research in a clear and attractive
manner.
As this book acts as an introduction to the basics of research meth-
ods, you will probably want to find out more about many of the
issues mentioned, so I have made suggestions for further reading at
the end of each chapter (‘Where to find out more’). You will notice
that research is riddled with technical terms, or what some people
would call jargon. The first time any of the terms are used they are
highlighted in bold and then I normally provide an explanation of
the meaning. In order to provide a useful way to remind you of the
definitions of the main technical terms used in this book (and for that
matter elsewhere too), I have included a glossary at the end which
includes all those terms highlighted in bold in the main text plus a
few extra ones you may come across in your other needing. You can
easily refer to the glossary from anywhere in the book.
Not only will reading this book give you an insight into the dif-
ferent aspects of research theory and practice and help you to under-
stand what is involved in carrying out a research project, it will also
help you to evaluate the claims made by academics, experts of all
kinds, politicians, advertisers, etc. by judging the quality of the evi-
dence provided by the research on which they base their arguments.
You don’t have to read the book from the beginning to the end, like
a novel. It can be used as a reference for finding out about the char-
acteristics of a particular research method, the meaning of a certain
term or about aspects of theory. However, the chapters are arranged
in the approximate sequence of the activities required for carrying
out a research project, so it can be used as a step-by-step guide to
doing your own research.
Finding out about things and trying to understand events and
situations are activities that symbolize the very essence of humanity.
At a time when we are bombarded with information, when press-
ing problems are ever present, when the opportunities for discovery
INTRODUCTION 3
are all around us, it is really useful, if not essential, to be familiar
with the methods for doing research – any research. This book will
help you to think clearly, to structure your enquiries and to come to
conclusions based on appropriate evidence and sound argument. It
will enable you to consolidate your knowledge and understanding
of your surroundings, and will also help you to hold your own in a
discussion and to critically analyse the claims and arguments made
by others.
PART I
RESEARCH THEORY AND
PRACTICE
One reviewer of my first draft of this book suggested that these first
five chapters did not deal with research methods at all. Strictly speaking,
if you take a purist’s view of what research methods are, he was cor-
rect. If you consider that research methods are only specific tech-
niques for collecting and analysing data in such a way that you can
come to reliable conclusions, then Part I of this book does not deal
with these. However, I believe that unless you know what research is
about, and understand the context in which these research methods
are used, you will not know which to use and why. Therefore, in Part
I of this book, I have provided an overview of the nature of research,
its theoretical foundations, what is involved in the process, what you
can do with it, and what makes good research.
In order to place research within its context, in Chapter 2 I have
provided you with a brief review of the theoretical basis of research
as an activity. I consider different ideas about what we can know and
how we can know it, and how we can get an understanding of the
world around us. You will see that this type of thinking has a long
history, probably ever since humans became aware of themselves as
being special within nature. The ability to reflect and use abstract
ideas set them apart from the animal and plant kingdom. The debate
revolves around to what extent humans can be autonomous from
their environment and society.
RESEARCH THEORY AND PRACTICE6
In Chapter 3, I look at how research projects are structured. Of
course, not all projects are the same, but they do all share some similar
features. For example, they all have some aims and an argument that
leads to some conclusions based on evidence of some kind. The ways
that the aims can be formulated are described, and the way that argu-
ments can be constructed are discussed.
The important issue of ethics is explored in Chapter 4. The
reliability of progress in knowledge is dependent on the honesty of
the researchers. It also often depends on the co-operation of mem-
bers of the public or particular sections of the population, who must
be protected from any adverse effects of the research process. Basically,
the principle behind ethical research is to cause no harm and, if pos-
sible to produce some gain for the participants in the project and in
the wider world.
Any piece of research will not be the first of its kind. There is
always a context in which the project is carried out and a history of
work that has gone before it. In Chapter 5, I consider how to review
the literature in relation to your chosen subject, where to find the
information and how to assess what you have found in relation to
your projected work. This is a basic scholarly exercise, but once you
have learned the skills needed to interrogate the accumulated knowl-
edge and theories of a subject, you will find that this is useful in
many aspects of life, particularly as we are bombarded from all sides
with claims and assertions.

RESEARCH BASICS
Research is a very general term for an activity that involves finding
out, in a more or less systematic way, things you did not know. A
more academic interpretation is that research involves finding out
about things that no-one else knew either. It is about advancing the
frontiers of knowledge.
Research methods are the techniques you use to do research. They
represent the tools of the trade, and provide you with ways to collect,
sort and analyse information so that you can come to some conclu-
sions. If you use the right sort of methods for your particular type of
research, then you should be able to convince other people that your
conclusions have some validity, and that the new knowledge you
have created is soundly based.
It would be really boring to learn about all these tools without
being able to try them out – like reading about how to use a plane,
chisel, drill etc. and never using them to make something out of a
piece of wood. Therefore courses in research methods are commonly
linked to assignments that require these methods to be applied – an
actual research project that is described in a dissertation or thesis, or
a research report. In the workplace, it is often the other way round.
When there is a perception that more information and understand-
ing is needed to advance the work or process of work, then ways are
sought how research can be carried out to meet this need.
RESEARCH THEORY AND PRACTICE8
Being a researcher is as much about doing a practical job as being
academically competent. Identifying a subject to research, finding
and collecting information and analysing it, presents you with a
range of practical problems that need to be solved. Over hundreds of
years, techniques, or methods, have been evolved to provide solutions
to these problems. The practice of research is closely bound up with
the theoretical developments that were promoted by philosophers
and key thinkers and practitioners in the sciences, right back to the
ancient Greeks. The debate about knowledge and how we acquire it is
rooted in philosophical thought (discussed in Chapter 2).
WHAT YOU CAN DO WITH RESEARCH
So what can we use research to do in order to gain this new knowledge?
Some of the ways it can be used one to:
Categorise. This involves forming a typology of objects, events
or concepts, i.e. a set of names or ‘boxes’ into which these can
be sorted. This can be useful in explaining which ‘things’ belong
together and how.
Describe. Descriptive research relies on observation as a means
of collecting data. It attempts to examine situations in order to
establish what is the norm, i.e. what can be predicted to happen
again under the same circumstances.
Explain. This is a descriptive type of research specifically designed
to deal with complex issues. It aims to move beyond ‘just getting
the facts’ in order to make sense of the myriad other elements
involved, such as human, political, social, cultural and contextual.
Evaluate. This involves making judgements about the quality
of objects or events. Quality can be measured either in an abso-
lute sense or on a comparative basis. To be useful, the methods of
evaluation must be relevant to the context and intentions of the
research.
Compare. Two or more contrasting cases can be examined to
highlight differences and similarities between them, leading to a
better understanding of phenomena.
Correlate. The relationships between two phenomena are inves-
tigated to see whether and how they influence each other. The
RESEARCH BASICS 9
relationship might be just a loose link at one extreme or a direct
link when one phenomenon causes another. These are measured
as levels of association.
Predict. This can sometimes be done in research areas where
correlations are already known. Predictions of possible future
behaviour or events are made on the basis that if there has been a
strong relationship between two or more characteristics or events
in the past, then these should exist in similar circumstances in the
future, leading to predictable outcomes.
Control. Once you understand an event or situation, you may be
able to find ways to control it. For this you need to know what
the cause and effect relationships are and that you are capable
of exerting control over the vital ingredients. All of technology
relies on this ability to control.
You can combine two or more of these objectives in a research project,
with sometimes one objective needing to be successfully achieved
before starting the next, for example you usually need to be able to
explain how something happens before you can work out how to
control it.
RESEARCH DESIGNS
There are numerous types of research design that are appropriate for the
different types of research projects. The choice of which design to apply
depends on the nature of the problems posed by the research aims. Each
type of research design has a range of research methods that are com-
monly used to collect and analyse the type of data that is generated by
the investigations. Here is a list of some of the more common research
designs, with a short explanation of the characteristics of each.
HISTORICAL
This aims at a systematic and objective evaluation and synthesis of
evidence in order to establish facts and draw conclusions about past
events. It uses primary historical data, such as archaeological remains
as well as documentary sources of the past. It is usually necessary to
carry out tests in order to check the authenticity of these sources.
RESEARCH THEORY AND PRACTICE10
Apart from informing us about what happened in previous times
and re-evaluating beliefs about the past, historical research can be
used to find contemporary solutions based on the past and to inform
present and future trends. It stresses the importance of interactions
and their effects.
DESCRIPTIVE
This design relies on observation as a means of collecting data. It
attempts to examine situations in order to establish what is the norm,
i.e. what can be predicted to happen again under the same circum-
stances. ‘Observation’ can take many forms. Depending on the type
of information sought, people can be interviewed, questionnaires
distributed, visual records made, even sounds and smells recorded.
Important is that the observations are written down or recorded in
some way, in order that they can be subsequently analysed. The scale
of the research is influenced by two major factors: the level of com-
plexity of the survey and the scope or extent of the survey.
CORRELATION
This design is used to examine a relationship between two con-
cepts. There are two broad classifications of relational statements:
an association between two concepts – where there is some kind of
influence of one on the other; and a causal relationship – where one
causes changes to occur in the other. Causal statements describe
what is sometimes called a ‘cause and effect’ relationship. The cause
is referred to as the ‘independent variable’, the variable that is
affected is referred to as the ‘dependent variable’.
The correlation between two concepts can either be none (no cor-
relation); positive (where an increase in one results in the increase in
the other, or decrease results in a decrease); or negative (where the
increase in one results in the decrease in the other or vice versa).
The degree of association is often measurable.
COMPARATIVE
This design is used to compare past and present or different parallel situ-
ations, particularly when the researcher has no control over events. It
RESEARCH BASICS 11
can look at situations at different scales, macro (international, national)
or micro (community, individual). Analogy is used to identify similari-
ties in order to predict results – assuming that if two events are simi-
lar in certain characteristics, they could well be similar in others too.
In this way comparative design is used to explore and test what condi-
tions were necessary to cause certain events, so that it is possible, for
example, to understand the likely effects of making certain decisions.
EXPERIMENTAL
Experimental research attempts to isolate and control every rel-
evant condition which determines the events investigated and then
observes the effects when the conditions are manipulated. At its sim-
plest, changes are made to an independent variable and the effects
are observed on a dependent variable – i.e. cause and effect. Although
experiments can be done to explore a particular event, they usually
require a hypothesis (prediction) to be formulated first in order to
determine what variables are to be tested and how they can be con-
trolled and measured. There are several classes of experiment – pre,
true, quasi, etc. which are characterized by the amount of checking
and control involved in the methods.
SIMULATION
Simulation involves devising a representation in a small and sim-
plified form (model) of a system, which can be manipulated to
gauge effects. It is similar to experimental design in the respect of
this manipulation, but it provides a more artificial environment in
that it does work with original materials at the same scale. Models
can be mathematical (number crunching in a computer) or physical,
working with two- or three-dimensional materials. The performance
of the model must be checked and calibrated against the real system
to check that the results are reliable. Simulation enables theoretical
situations to be tested – what if?
EVALUATION
This descriptive type of research is specifically designed to deal with
complex social issues. It aims to move beyond ‘just getting the facts’,
RESEARCH THEORY AND PRACTICE12
by trying to make sense of the myriad human, political, social, cultural
and contextual elements involved. There are a range of different
approaches of evaluation models, for example, systems analysis –
which is a holistic type of research looking at the complex interplay
of many variables; and responsive evaluation – which entails a series
of investigative steps to evaluate how responsive a programme is to
all those taking part in it. A common purpose of evaluation research
is to examine the working of projects from the point of view of lev-
els of awareness, costs and benefits, cost-effectiveness, attainment of
objectives and quality assurance. The results are generally used to
prescribe changes to improve and develop the situation.
ACTION
Essentially, this is an ‘on the spot’ procedure, principally designed to
deal with a specific problem found in a particular situation. There is
no attempt made to separate the problem from its context in order
to study it in isolation. What are thought to be useful changes are
made and then constant monitoring and evaluation are carried out
to see the effects of the changes. The conclusions from the findings
are applied immediately, and further monitored to gauge their effec-
tiveness. Action research depends mainly on observation and behav-
ioural data. Because it is so bound up in a particular situation, it is
difficult to generalize the results, i.e. to be confident that the action
will be successful in another context.
ETHNOLOGICAL
Ethnological research focuses on people. In this approach, the researcher
is interested in how the subjects of the research interpret their own
behaviour rather than imposing a theory from outside. It takes place
in the undisturbed natural settings of the subjects’ environment. It
regards the context to be as equally important as the actions it stud-
ies, and attempts to represent the totality of the social, cultural and
economic situation. This is not easy as much of culture is hidden
and rarely made explicit and the cultural background and assump-
tions of the researcher may unduly influence the interpretations and
descriptions. Moreover there can be confusions produced by the use
of language and the different meanings which may be given to words
by the respondents and researcher.
RESEARCH BASICS 13
FEMINIST
This is more of a perspective than a research design that involves
theory and analysis that highlight the differences between men’s and
women’s lives. Researchers who ignore these differences can come to
incorrect conclusions. However, everyone is male or female, so value
neutrality is impossible as no researcher practises research outside
his or her system of values. No specific methods are seen to be par-
ticularly feminist, but the methodology used is informed by theories
of gender relations. Although feminist research is undertaken with a
political commitment to identify and transform gender relations, it
is not uniquely political, but exposes all methods of social research
as being political.
CULTURAL
Many of the prevailing theoretical debates (e.g. postmodernism,
poststructuralism etc.) are concerned with the subjects of language
and cultural interpretation. Cultural research provides methodolo-
gies that allow a consistent analysis of cultural texts so that they
can be compared, replicated, disproved and generalized. Examples of
approaches to the interpretation of cultural texts are: content analy-
sis, semiotics and discourse analysis. The meaning of the term ‘cul-
tural texts’ has been broadened from that of purely literary works
to that of the many different forms of communication, both formal
such as opera, TV news programmes, cocktail parties etc., and infor-
mal such as how people dress or converse.
DECIDING ON YOUR TYPE OF RESEARCH
It is your research interest that decides the nature of your research
problem, and this will indicate the appropriate type of research to fol-
low. Once the objectives of a research project have been established,
the issue of how these objectives can be met leads to a consideration
of which research design should be chosen. The research design pro-
vides a framework for the collection and analysis of data and subse-
quently indicates which research methods are appropriate. You can
combine two or more types of research design, particularly when
your subject combines the study of human behaviour with that of,
for example, economics, technology, legislation or organizations.
RESEARCH THEORY AND PRACTICE14
The different types of research design may involve the use of their
own specific types of research methods, developed specifically to
solve the problems inherent in that design. However, some methods
are widely used across many research types.
WHERE TO FIND OUT MORE
Apart from continuing to read this book, there are other introductions
to research that you may wish to check out. Most books on this sub-
ject cover the whole sequence of doing research. The following books
are aimed at undergraduate and postgraduate research and selective
reading of the preliminary chapters will provide further guidance on
research basics. Each gives a slightly different view of the issues,
so refer to as many as possible. You can probably do this in the
library without …
