This document provides an overview of research and quantitative research. It defines research and differentiates between qualitative and quantitative research. Quantitative research is described as a systematic investigation that uses measurable, numerical data to test hypotheses, explore relationships, make predictions and generalize findings to a population. It relies on larger sample sizes, probability sampling, and structured data collection to provide results with less subjectivity and higher generalizability compared to qualitative research.

2. 1. define research;
2. differentiate the two
kinds of research; and
3. describe quantitative
research.
In this lesson,
we shall learn
how to:

3. The word research - and the act of doing
research- is commonly associated with using
the internet, particularly Google or other search
engines and websites, to find out information
about a certain topic.
What is
research?

4. Using Google & other
search engines found on
the internet is just one of the
various means to gather
data in order to complete
a study. Learning
to be proficient in using the
internet to search facts
about a topic will definitely
help you in your research.

5. RESEARCH

6. ● It is a systematic search for truth.
● Through research, new and
original information, ideas about
the world we live in, are obtained.
Here are some definitions
of research...

7. ● Research is search for
knowledge.
● Research is defined as a
scientific and systematic search
for information on a specific
Also….

8. ● Research is a careful and systematic
study and inquiry in some field of
knowledge.
● Research is an investigation of a certain
phenomenon or results of previous
studies to find out their present
Moreover...

9. Research means
organized and
systematic way of
finding answers to
the questions.

10. Without a
question, research
has NO FOCUS,
DRIVE OR
PURPOSE.

11. Let’s move on
to the two
kinds of
research.

12. RESEARCH
QUALITATIVE QUANTITATIVE

13. How do you
think qualitative
research differs
from
quantitative
research?

14. Qualitative
- requires non-numerical data,
which means that the research
uses words rather than numbers
to express the results, the inquiry
or investigation about people’s
thoughts, beliefs, feelings, views
and lifestyles regarding the
object of the study.
- involves measurement of
data. Thus, it presents
research findings referring to
the number or frequency of
something in numerical forms
(using percentages, fractions,
numbers).
Quantitative
Here’s the difference between
qualitative and quantitative research.

15. Now, let’s get
to know more
quantitative
research.

16. Quantitative Research
- a systematic investigation of
observable phenomena where the
researcher gathers quantitative
or numerical data and subjects
them to statistical data.

17. Quantitative Research
The main goals of quantitative
research are to test
hypotheses, explore causal
relationships, make
predictions, and generalize the
findings within a population.

18. Quantitative Research
Compared to qualitative research,
quantitative research typically uses
larger samples (or sets of
participants in the study) and
primarily utilizes probability
sampling.
Do you know
that….

19. Are you familiar
with probability
sampling?

20. Quantitative Research
Probability sampling is
a type of sampling that
is highly randomized.
Well...

21. Quantitative
research has lower
level of subjectivity
and
a higher rate of
generalizability.

22. Generalizability
It refers to the extent
to which the findings not
only represent the
samples but also the
population at large.

23. I guess you are
now quite familiar
with quantitative
research. Let us
further discuss its
characteristics.

24. Characteristics
of
QUANTITATIVE
RESEARCH

25. ● The data are usually gathered using a more
structured instrument.
● The results are based on larger sample sizes
that are representative of the population.
● The research study can usually be replicated
or repeated, given its high reliability.
The characteristics of quantitative research
include the following:

26. ● The researcher has a clearly
defined research question to
which objective answers are
sought.
● All aspects of the study are
carefully designed before
the data is collected.
Do you know
that….

27. ● Data are in the form of
numbers and statistics.
● The researcher uses tools
such as questionnaires or
computer software, to
collect numerical data.
