Research onion shows
the phases that a researcher must cover while developing research strategy.
According to the figure of research onion, first, the philosophies of the
research should be defined which serve as the starting point of research. After
that, the approaches, strategies, choices, time horizons and techniques and
procedures are identified step by step. The advantage of research onion is that
it provides a series of step to researcher to take while conducting or
developing research methodology.
1.
Philosophies:
The philosophies of the research provide a set of belief on what basis the
research is being conducted. Research philosophies also depend on the
objectives of the study being conducted. According to research onion, there are
four main research philosophies:
·
Positivism: In positivism philosophy,
only the factual information gained via observation is considered. The
researcher role is limited to data collection and interpretation and research
findings are usually observable and quantifiable. In addition, the researcher
personal or any other human interests have no place within the study.
·
Realism: The philosophy of realism is that
the researcher and reality are independent and will not create biased results.
The only difference is that realism believes that scientific method is not
perfect.
·
Interpretivism: Interpretivism involves researchers to interpret elements of the study,
thus interpretivism integrates human interest into a study. In this philosophy,
it is important for the researcher as a social actor to appreciate differences
between people.
·
Pragmatism: Pragmatism believes that the
concept that supports action is only relevant. Further, only one way can’t be
relevant so there are many ways to interpret things. Research questions are the most important factor in this philosophy.
2. Approaches
·
Deductive: Deductive means that you
start with a statement or question and your research sets out to answer it. In
other words, the deductive approach develops the
hypothesis based upon pre-existing theory. This approach is suitable when
research is about whether the observed action satisfies the result of previous
research.
·
Inductive:
Inductive is the opposite of deductive as it starts with observation and the
end result is the generation of new theory.
3.
Strategies:
Research strategies involves plan of future such as how he/she intends to do
each and every step in order to accomplish the goal of the research.
·
Experiment: Experimental research refers to the strategy of creating a research
process that examines the results of an experiment against the expected results.
·
Survey:
In survey, the researcher considering size of population selects sample and
sends them standardized questionnaire to collect data and conclude results.
·
Case study: Case study research is the assessment of an object or event in order to
draw result from study. Case study is suitable in financial research such as
comparing the effect of investment in difference scenario.
·
Action Research: This strategy is
concerned with addressing issues to find and implement solutions. The process
of Action Research moves from a clear objective to diagnosis of the problem and
generation of a list of actions to solve the problem.
·
Grounded theory: Grounded theory is a qualitative methodology that draws on an inductive
approach whereby patterns are derived from the data as a precondition for the
study.
·
Ethnography: Ethnography involves the close observation of people from their own
perspective and aims to understand their customs, habits and mutual
differences.
·
Archival research: This strategy centers
its data collection on existing data sets or archive documents. This allows for
exploratory, explanatory or descriptive analysis of changes tracked over a long
period of time. However, the accuracy and breadth of information available may
be an issue for a researcher relying solely on this type of secondary data.
4.
Choices
·
Mono method: The mono-method involves using one research approach (qualitative or
quantitative methodology) for the study.
·
Mixed methods: The mixed-methods required the use of two or more methods of research,
and usually refer to the use of both a qualitative and a quantitative
methodology.
·
Multi-method: The multi-method approach is where the research is divided into
separate segments, with each producing a specific dataset; each is then analyzed
using techniques derived from quantitative or qualitative methodologies
5.
Time
horizons: The Time Horizon is
the time framework within which the project is intended for completion
·
Cross-sectional: The cross sectional time horizon is one already established, whereby the
data must be collected. The data is collected at a certain point. This is used
when the investigation is concerned with the study of a particular phenomenon
at a specific time.
·
Longitudinal: A longitudinal time horizon for data collection refers
to the collection of data repeatedly over an extended period, and is used where
an important factor for the research is examining change over time.
6.
Techniques
and procedures: Data collection and analysis is
dependent on the strategies and approach used. The process used at this stage
of the research contributes significantly to the studies overall reliability
and validity. Regardless of the approach used in the project, the type of data
collected can be separated into two types: primary and secondary.
·
The Primary Data: Primary data is
first-hand sources, or the data derived from the respondents in survey or
interview data.
·
Secondary Data: Secondary data is
that which is derived from the work or opinions of other researchers.
