Research Approaches

Dr Lo’ai Tawalbeh

University of the Cumberlands

You need to design a research programme

Convinces the reader that you know what you are doing

Provides the academic component of your research project (at least 50% of the work)

Is a ‘top-down’ approach to help you to:

Manage your research project

Make sure the research methodology is suitable

Write up your research in a clear and precise way

The research programme

Begin with the research background

then

Focus on research question, problem or advantage

then

Choose an appropriate research approach

then

Include suitable research methods to carry out tasks

then

Select suitable research techniques for doing:

- Data collection

- Data analysis

Research Programme

Research Background

- Problem solution

- Advantage/improvement

- Advance in knowledge

Research Approach

Research Method

e.g. qualitative

research

Must be appropriate to background

(Other approaches not used)

(Other methods not used)

e.g. survey research

Must be appropriate to

Research Technique

e.g.

questionnaire

(Other methods not used)

Chosen approach

Must be appropriate to Method

The selection process should be narrated

thoroughly and critically.

Overview of Research Approaches 1

Quantitative research methods

Originally developed in the natural sciences

Assumes that the world has an objective reality that can be measured (positive viewpoint)

Involves the use of statistical methods (surveys, analysis)

Qualitative research methods

Originally developed in the social sciences

Assumes that reality is subjective (interpretive viewpoint)

Involves opinions, viewpoints, case studies

Some researchers use the terms ‘objective’ and ‘subjective’ to describe alternative approaches.

Attempts have been made to combine the two approaches – called ‘triangulation’

Overview of Research Approaches 2

Exploratory Research

Often conducted because problem has not been clearly defined

Helps pick the best research design, data collection method etc.

often relies on secondary research (e.g. reviewing available literature and/or data) or qualitative approaches (e.g. interviews with participants)

Exploratory research is used in previously uncharted areas, or by those who don't yet know enough about their topic…is this you?

Overview of Research Approaches 3

Confirmatory Research

Performed to ‘confirm’ an assumption or theory.

Involves testing against a hypothesis or specific assumptions

Usually involves the use of quantitative and/or positivist research and surveys, experiments or observations

The more your topic has been researched by others, the more it is expected that you should use confirmatory research.

Hypotheses – things that can be tested 1

Variables - the building blocks of hypotheses

Something that varies or changes as a result of some effect or something happening

Note - something that never changes is called a constant.

In technology research, we deal mostly with two types

of variables: independent and dependent

Independent variables are those things thought to be the cause of or to bring about change in other variables

Dependent variables are those things that are changed or affected by independent variables

Hypotheses – things that can be tested 2

Hypotheses are simply ‘if-then’ statements designed

to examine and exploit differences in variables, e.g.:

Differences in Variable A have no relationship to differences in Variable B (i.e. the null hypothesis)

If Variable A changes, then Variable B changes (i.e. Variable A affects Variable B in any way)

= a non-directional hypothesis

If Variable A increases, then Variable B increases, or If Variable A decreases, then Variable B decreases

= directional hypothesis

The more specific you make your hypotheses, the better as you may be able to use more powerful statistics and base your work on strong ‘theoretical underpinnings’

Quantitative, Positivist Research (QPR)

Derived from the work of Karl Popper* (1980).

QPR has two main points:

Emphasis on quantitative (statistical) data

Assumes problem can be represented statistically

Seeks to derive meaning from statistics

Emphasis on a positivist philosophy*

Recognises ‘scientific evidence’

Theories can be refuted or ‘falsified’, but can never be exactly proven to be true

In this view research is essentially ‘scientific’

Positivist Research Approaches

Positivists generally assume that reality is objectively given and can be described by measurable properties which are independent of the observer (researcher) and his or her instruments.

Positivist studies generally attempt to test theory, in an attempt to increase the predictive understanding of phenomena.

Research is positivist if there is evidence of formal propositions, quantifiable measures of variables, hypothesis testing, and the drawing of inferences about a phenomenon from the sample to a stated population.

Quantitative, Positivist Research (QPR)

The production of ‘scientific evidence’ is based

on the 4 step process of ‘deduction’:

Testing internal consistency of data (does it ‘add up’?)

Producing a hypothesis that can be tested (i.e. based on a theory or principle that is already accepted)

Comparing the testable data with the hypothesis through (e.g. statistical) analysis

Validation aimed at ‘falsifying’ (i.e. refuting) or ‘proving’ the hypothesis from the results of analysis

If the results do not contradict it, the hypothesis must be

(temporarily) accepted. The ‘truth’ is never permanent.

Range of QPR Methods

Field experiment

Lab experiment

Simulation experiment

Field study 

Archival research 

May be placed into the following research types:

Exploratory – ‘finding out’ new knowledge

Confirmatory – testing existing knowledge

Qualitative Research Methods

3 approaches (or epistemology) in qualitative research:

Orlikowski and Baroudi (1991)

Qualitative research can be Positivist

Interpretive Research Approaches

Starts out with the assumption that access to reality is only through social constructs such as language, consciousness and shared meanings.

Interpretive studies generally attempt to understand phenomena through the meanings that people assign to them and interpretive methods of research are "aimed at producing an understanding of the context of the…system, and the process whereby the …system influences and is influenced by the context" (Walsham 1993, p. 4 - 5).

Interpretive research tries to focus on the full complexity of human sense-making as the situation emerges (Kaplan and Maxwell, 1994).

Critical Research Approaches

Critical researchers assume that social reality is historically constituted and is produced by people.

Although people can consciously act to change their circumstances, critical researchers recognize that their ability to do so is restricted by various social, cultural and political factors.

The main task of critical research is seen as being one of social critique, where the restrictive conditions of a scenario or case study are examined.

Critical research tries to focus on the oppositions, conflicts and contradictions in a situation, and seeks to help to eliminate the causes of the problem

Qualitative Research Methods

Action Research

Researcher involved in/influences scenario

Ethical implications?

Case Study

Can be current or historical

Researcher does not influence research

Grounded Theory

Seeks to develop theory that is grounded in data

Data systematically gathered and analyzed.
