OBJECTIVE
Identify technical
terms used in
research

Research
Is this important? Why or Why not?

The main
purpose of
research is to
inform action,
to prove a
theory, and
contribute to
developing
knowledge in a
field or study.

Research is
required not just
for students and
academics, but for
all professionals
and
nonprofessionals
alike.

What is “Research?”
Research can be defined
as “a systematic and
scientific procedure of data
collection, compilation,
analysis, interpretation,
and implication pertaining
to any problem.”

What is “Research?”
It involves the quest for
answers to unsolved problems.
Moreover, research methods
may be defined as “a systematic
and scientific procedure of data
collection, compilation, analysis,
interpretation, and implication
pertaining to any problem
(Bajpai, 2011, p.4).”

Two Major Types of Research Methods
QUANTITATIVE
RESEARCH
QUALITATIVE
RESEARCH

Quantitative
research
Quantitative research
“describes, infers, and
resolves problems using
numbers. Emphasis is placed
on the collection of numerical
data, the summary of those
data and the drawing of
inferences from the data.”

Qualitative research
Qualitative research, on the
other hand, is based on words,
feelings, emotions, sounds and
other non-numerical and
unquantifiable elements. It has
been noted that “information is
considered qualitative in nature
if it cannot be analyzed by
means of mathematical
techniques (Picknell, 2021).”

Research
It is collecting data
and information,
learning and finding
new things.

Research
It is also an advanced
knowledge which follows a
systematic process of
collecting and analyzing
information in order to
understand more the
phenomena under study.

Research
Action research, thesis,
dissertation, and case
study are examples of
research.

Concept
It is a term that abstractly describes and
names an object, a phenomenon, or an idea.
Examples of concepts include common demographic
measures:
- Income – P5,000 – P8,000
- Age – 18 y/o – 20 y/o
- Education Level – High School Graduate, College
Graduate, Post Graduate
- Number of Siblings – 3 siblings in the family, 4 or
more siblings in the family

Theory
It is an organized body of concepts and
principles intended to explain a
particular phenomenon.
Examples include the theory of relativity,
atomic theory, theory of evolution, and
quantum theory

Quantitative Method
This is a method that focuses on numbers,
objective hard data. It proves hypotheses
by statistical analysis and scientific
method.
It is called a formal, objective, systematic
process in which numerical data is used to
obtain information about the world.
It is used to describe variables.
It examines relationships among variables.

Quantitative Method
Example is a drug abuser telling you
how many pills they consume per
week.

Qualitative Method
It uses words instead of numbers to display
data. It focuses on feelings not numerical
data. Small amount of participants involved
in a qualitative research study.
This kind of research method utilizes
interviews, archived written information,
and observations to measure the
significance of a relationship between
variables.

Qualitative Method
Examples is a drug abuser telling you
how they feel about abusing drugs.

Variables
These are any quality of a
person, group subject, event,
condition or situation that varies
or takes on different values.

Variables
Examples are age, sex, business
income and expenses, country of
birth, capital expenditure, class
grades, eye color and vehicle type

Hypothesis
Hypothesis is a logical
supposition, a reasonable guess,
and educated conjecture. It
provides a tentative explanation
of a phenomenon under
investigation.

Hypothesis
For example, a researcher might be
interested in the relationship
between study habits and test
anxiety. The researcher would
propose a hypothesis about how
these two variables are related, such
as "Test anxiety decreases as a result
of effective study habits."

Sampling
Sampling it is the process
of selecting participants
who are representatives of
a larger population – gain
an understanding of a
larger population.

Sampling
For example, a random sample
may include choosing the names of
25 employees out of a hat in a
company of 250 employees. The
population is all 250 employees, and
the sample is random because each
employee has an equal chance of
being chosen.
