Methodology is the systematic, theoretical analysis of the methods applied to a field of study.
It comprises the theoretical analysis of the body of methods and principles associated with a branch of knowledge.
Methodology is useful to guide and help in order to obtain the objectives of a research project.
This consists of the purpose, assumptions, limitations, philosophy, strategy, data collection method, sampling method, scaling, data analysis, validity and reliability of the research.
The methodological choices reported give guidelines for the way which should collect necessary information for this study investigation and analyzing matters.

RESEARCH PURPOSE
A research design is a detailed plan or framework that assists to guide researcher through the
research process, allowing a superior probability to obtain research objectives. Research purpose
regularly is classified into five classifications as follows:
▫ Exploratory : In exploratory research the researcher conducts research into a research problem
where there currently exists very little, if any, earlier work to refer to. The aim of this type of
research is to develop a better insight into a particular topic, leading to the development of a set of
hypotheses.
▫ Explanatory : It refers to the studies that establish causal relationship between variables. The
emphasis here is on studying a situation or a problem in order to explain the relationship between
the variables. In the explanatory study, theories or at least hypotheses are used by researchers to
account for the forces that caused certain phenomenon to happen.
▫ Descriptive : Descriptive investigation explains the phenomena, as it exists. It is used to determine
and gain data on the characteristics of a particular issue. Descriptive research is frequently used
when a problem is well organized and there is no intention to examine the effect and cause relations.
▫ Reporting : This may be made only to provide an account or to summation of some data or to
generate some statistics. The information readily available and task may be quite easy.
▫ Predictive :It provides a plausible expounding for an event after it has happened and it able to
presage when and where the event will occur.

RESEARCH PHILOSOPHY
Two terms often used to describe the main research philosophy which are qualitative
and quantitative.
▫ Quantitative Study : This examines data that are numerical. A quantitative
study is determined by studying some variables on many elements and is also a
structured and formalized method. The purpose of quantitative research is to
specify the communication between independent variable and dependent or
outcomevariable in a population.
▫ Qualitative Study: Qualitative inquiry refers to all non numeric data or data that
have not been quantified. It examines data that are narrative. It shares good
company with the most rigorous quantitative research. Qualitative research is
link with both inductive and deductive studies. It is viewed as subjective and
involvesdata collection methodssuch as interviews.

RESEARCH STRATEGY
Research strategy refers to the common plan that researcher follows to answer the research
questions. The types of research strategy and their associated questions are:
▫ Action research (how)
▫ Case study (how, why)
▫ Experimental (how, why)
▫ Survey (who, what, where, how many, howmuch)
▫ Timehorizon (who, what, where, how many, how much)
▫ Archivalanalysis (who, what, where, how many, howmuch)
▫ Comparative(how, why, what)
8. 8
DATA COLLECTION METHOD
There are two types of data, the first are primary data which and the second are secondary data, that is
data that has already been published.
▫ Primary Data : It is information gathered for the purpose of study. Researcher collect data using a range
of collection tools such as interviews, observation and questionnaires, rather than simply relying on
existing data sources. In otherwords, thedataare unique to theparticular study.
▫ Secondary Data : In contrast to primary data, These kind of data have been collected by other
researchers. Secondary data encompass a range of different sources. Some of these sources are; general
reports, theses, news, dictionaries, bibliographies, encyclopedias and citation indices

SCALING METHODS
Questionnaire items are divided to two main categories:
▫ Open question is one in which the respondent does not have to indicate a specific response. Open questions
have a tendency to generate lengthy answers.
▫ Closed question is one in which a respondent has to choose from a limited number of potential answers.
Scaling methods are :
Rating Scales
Graphic Rating Scales
Itemized Rating
Scales
Comparative Rating
Scales
Attitude Scales
Semantic Differential
Likert Scale

Validity
Internal
Construct Content
Face Sampling
External
External validity is the extent to
which the findings of study can
be generalized to other cases
or settings.
Face validity concerns the extent to which an
instrument measures what it is supposed to
measure.
Sample validity ensures that
measure includes all areas
within the nature of study.
It is defined as
establishing correct
operational measures
for the concept being
studied. In this
regards, questionnaire
items should be
discussed and
approved with experts
in the field of study.
Validity describes how well
the collected data covers the
actual area of investigation.
