Title: Chapter 5 Formulating the research design


1
Chapter 5 Formulating the research design
2
Underlying issues of data collection and analysis
  • "Well begun is half done
  • --Aristotle, quoting an old proverb

3
Underlying issues of data collection and analysis
  • Research design focuses upon turning a research
    question and objectives into a research project.
    It considers
  • Research strategies
  • Research choices and
  • Time horizons

4
Research Design and Tactics
  • The research onion
  • Saunders et al, (2009)

Figure 5.1 The research onion
5
Research Design
  • The research design needs
  • Clear objectives derived from the research
    question
  • To specify sources of data collection
  • To consider constraints and ethical issues
  • Valid reasons for your choice of design

6
The Process of Research Design
  • As you start thinking about your
  • research question(s) you will also be
  • thinking of the purpose of your research

7
Classification of the research purpose
  • Exploratory research
  • Descriptive studies
  • Explanatory studies

8
Classification of the research purpose
  • Exploratory research
  • Find out what is happening, to clarify your
    understanding of a problem.
  • 3 ways for conducting
  • A search of the literature
  • Interview experts in the subject
  • Conducting focus group interviews
  • Flexible and adaptable to change

9
Classification of the research purpose
  • Descriptive studies
  • Its object is to portray an accurate profile nof
    persons, events or situations.
  • Usually a research cannot be simply descriptive
    since the readers reaction would be SO WHAT?
  • So it is a means to an end, not an end in itself

10
Classification of the research purpose
  • Explanatory studies
  • Studies that establish causal relationships
    between variables

11
Research Strategies
  • Experiment Action research
  • Grounded theory Survey
  • Ethnography Case study
  • Archival research

12
Research Strategies
  • An experiment will involve
  • Definition of a theoretical hypothesis
  • Selection of samples from know populations
  • Random allocation of samples
  • Introduction of planned intervention
  • Measurement on a small number of dependent
    variables
  • Control of all other variables

13
Research Strategies
  • A classic experiment strategy

Saunders et al, (2009)
Figure 5.2 A classic experiment strategy
14
Research Strategies
  • Survey key features
  • Popular in business research
  • Perceived as authoritative
  • Allows collection of quantative data
  • Data can be analysed quantitatively
  • Samples need to be representative
  • Gives the researcher independence
  • Structured observation and interviews can be used

15
Research Strategies
  • Case Study key features
  • Provides a rich understanding of a real life
    context
  • Uses and triangulates multiple sources of data
  • A case study can be categorised in four ways
  • and based on two dimensions
  • single case v. multiple case (more ability to
    generalize)
  • holistic case(choose 1 organization as a whole)
  • v. embedded case(some departments or activities)
  • Yin (2003)

16
Research Strategies
  • Action research key features
  • Research IN action - not ON action focusing on
    the purpose
  • Involvement of practitioners in the research
  • The researcher becomes part of the organisation
  • Promotes change within the organisation
  • Can have two distinct focii (Schein, 1999)
  • the aim of the research and the needs of the
    sponsor

17
Research Strategies
  • The action research spiral
  • Saunders et al, (2009)

Figure 5.3 The action research spiral
18
Research Strategies
  • Grounded theory key features
  • Inductive deductive approach
  • Theory is built through induction and deduction
  • Helps to predict and explain behaviour
  • Develops theory from data generated by
  • observations
  • Is an interpretative process, not a
    logico-deductive one
  • Based on Suddaby (2006)

19
Research Strategies
  • Ethnography key features
  • Inductive approach
  • Aims to describe and explain the social world
    inhabited by the researcher
  • Takes place over an extended time period
  • Is naturalistic
  • Involves extended participant observation such as
    studying gorillas in their natural habitat

20
Research Strategies
  • Archival research key features
  • Uses administrative records and documents as the
    principal sources of data
  • Allows research questions focused on the past
  • Is constrained by the nature of the records and
    documents
  • Example historical research

21
Research Strategies
  • The role of the practitioner-researcher
  • Key features
  • Research access is more easily available
  • The researcher knows the organisation
  • Has the disadvantage of familiarity
  • The researcher is likely to their own assumptions
  • and preconceptions
  • The dual role requires careful negotiation

22
Multiple research methods
  • Research choices
  • Saunders et al, (2009)

Figure 5.4 Research choices
23
Multiple research methods
  • Multiple method
  • refers to those combinations where we use more
    than one data collection technique but restricted
    within either quantitative or qualitative world
    view.
  • Mixed method approach
  • Refers to an approach where both , quantitative
    and qualitative data collection techniques are
    used.

24
Multiple research methods
  • Reasons for using mixed method designs
  • (Table 5.1 )
  • Triangulation
  • Facilitation
  • Complementarity
  • Generality
  • Aid interpretation
  • Study different aspects
  • Solving a puzzle
  • Source developed from Bryman (2006)

25
Time Horizons
  • Select the appropriate time horizon
  • Cross-sectional studies the study of a
    phenomenon at a particular time. Because of time
    restrictions
  • Longitudinal studies it has the capacity to study
    change and development

26
Credibility of research findings
  • Important considerations
  • Reliability extent to which your data
    collection techniques will yield consistent
    finding (see threats)
  • Validity concerned with whether findings are
    really about what they appear to be about (see
    threats)
  • Generalisability whether findings may be equally
    applicable to other research settings such as
    other organizations
  • Logic leaps and false assumptions your research
    design should have a logical flow and assumptions
    that can be defended.

27
Research design ethics
  • Remember
  • The research design should not subject the
    research population to embarrassment, harm or
    other material disadvantage
  • Ex some universities do not allow collecting data
    from population not aware that it is subject of
    research
  • Adapted from Saunders et al, (2009)

28
Summary Chapter 5
  • Research design turns a research question and
    objectives into a project that considers
  • Strategies Choices Time horizons
  • Research projects can be categorised as
  • Exploratory Descriptive Explanatory
  • Research projects may be
  • Cross-sectional Longitudinal

29
Summary Chapter 5
  • Important considerations
  • The main research strategies may combined in the
    same project
  • The opportunities provided by using multiple
    methods
  • The validity and reliability of results
  • Access and ethical considerations
