What are the differences between qualitative and
quantitative method?
What are the major research methods?

The differences between qualitative
and quantitative methods :
Qualitative Methods Quantitative Methods
Collecting non-numeric data Collecting numerical data that can
be quantified
Methods include focus
groups, in-depth interviews,
and reviews ,content
analysis,observation
Methods include questionnaire
surveys,reviews, content
analysis,observation
This is an inductive process
which is used to formulate
theory.
This is a deductive process which
is used to test pre-specified

concepts, constructs, and
hypotheses that make up a theory
It describes a problem or
condition from the point of
view of people experiencing it
it provides observed effects of a
program on a problem or
condition

( Qualitative Methods ) ( Quantitative Method )
Text-based Number-based
No statistical tests Statistical tests are used for
analysis
Can be valid and reliable:
depends on skill of
the researcher
Can be valid and reliable:
depends on the measurement
device or instrument
Take less time on the
planning end and more time
during the analysis process
Take more time on the planning
end and less time during the
analysis process
Less generalizable More generalizable

Experimental Research

In-depth interview/
Focus groups
Participant observation
Content analysis
observation
Questionnaire Surveys

•
It is a research project by looking at
sources like encyclopedias and other
reference books, CD-ROMs, community
surveys, government reports and
Australian Bureau of Statistics (ABS)
data.

•
Tell us what is already known about
your research area.
•
These information you collect will be
both qualitative and quantitative.

It is used for historical research
FOR EXAMPLE: create a new kind of
medicine , a new machine for
education,agriculture,Industry

It is a method which we carry out
interviewing small number of people
(ten or less) from whom you need a lot

of detailed information, consider using
individual in-depth interviewers.
Typically we would develop a list of
open-ended questions and base your
interview around these.

FOR EXAMPLE
Hypothesis :students nowadays are lazier than ones
in the past
Interview some experienced
Headmasters,teachers

A hypothesis “Students whose major is
English at Tay Nguyen University are very
deligent”
Interview some teachers who taught
them and ask if they agree or not
Interview some students how many time
they spend for studying

A focus group is similar to an in-
depth interview but you gather the
information for a small discussion
group, usually up to eight people.

For example:
We want to know if the teaching method
that teacher A use is effective or not . We
interview about 5 groups of students in
different classes who used to learn with

his method.

They are useful for
explanatory and evaluate
researches

It is a method which we use to analyze
existing material such as newspapers,
historical and other documents, television
programs, magazines or books.

It is used for descriptive ,
explanatory and evaluative research

If we want to analyze “climate change",
you can use the information on newspapers,
historical documents
FOR EXAMPLE

For example:
We analysize a graph which show world
population growth or show the number of
people who suffer from AIDS in Africa to
find out how it changes and what
information we can collect.

It is a method which we look at or
observing some form of behaviour

It is used for descriptive and evaluative research

FOR EXAMPLE
Evaluate the quality of A high school
By observing students at this high school.
Do they go to school on time?
Are they aware of protecting public
properties?
How do their attitudes towards study?
Do they follow the principles of the school?


It is the method that we participate in what we are researching

It is used for descriptive and evaluative research
For example
Evaluating the food quality of a restaurant,we
participate in observing the way the chefs cook

For example
Evaluating the food quality of a restaurant,we
participate in observing the way the chefs cook
A research: The differences about lifestyle between
peole living in rural areas and ones in urban areas
We should live those areas to observe
