The epistemological foundations of quantitative research

The text delves into the epistemological foundations of quantitative research, emphasizing the interplay between pragmatism, experiential realism, and post-positivism. It explains that epistemology, derived from the Greek word for knowledge, is the philosophy of understanding.

The epistemological foundations of quantitative
research

The main advantages of quantitative approach.

Replicabilidad

focuses
can be repeated at any other time and place obtaining the same results.
hypothesis testing based on a well-defined plan and clear objectives

optimize time and effort

determine the cause and the consequence of the investigated problem.
greater precision to avoid errors and subjectivity
in analyzing and describing the results obtained

use of a quantitative approach

predictive generalizations of something that needs to be tested.
meaningful to draw conclusions.
provides larger sample size approximations
simplifies
how often "situations" occur
possibility of measuring

Advantage

Eliminate bias
The results achieved are statistical.

they are verifiable.

Extensive range of data analysis
Statistics as a tool, allows a broader collection of data obtained from groups of larger samples, it can be a limitation in other situations.
Quick data collection
The data collection methods and the way they are analyzed using statistics saves time and reduces waste of resources.
Collect reliable and accurate data
The use of numbers makes the researchers see the subject of study represented in an impartial and precise way to analyze it objectively.

The use of statistical data

measures
researchers allow them to know how to interpret the results obtained.

standardized.

reliable

definitive

It can
confirm
verify

Focus

It is an investigation on a specific problem through the application of an adopted scientific approach
counting
observing
analyzing
using statistical techniques
approach of a scientific nature

The epistemological foundations of quantitative research

Pragmatism

mixed methods
qualitative
quantitative
that the meaning and truth of any idea is a function of its practical results

Epistemologies underlying theory and practice

postmodermism
not accepting rational findings
there is no probability of having objective knowledge
science is not universal

culture is changeable.

criticalism
objective

Publicize and challenge power structures.

changing the existing and limiting social conditions

deep appreciation and appreciation of society and culture

change limiting social conditions.

interpretivism
to group different approaches

it is vital to see the differences that characterize people.

Through social constructions such as language, consciousness, shared meanings and instruments
interprets the components of the study

incorporates human interest in a study.

critical realism

prior understanding of other theories and concepts

all observation is fallible or imperfect

there is a reality independent of our thinking about which science can study

subjectivism
Subjectivism gives primacy to subjective experience as fundamental of all measure and law.
our own mental activity is the only unquestionable fact of our experience
positivism
valid knowledge (certainty or truth) is found only in this a posteriori knowledge.
Sensory experience, interpreted through reason and logic, constitutes the exclusive source of all true knowledge.
philosophical theory stating that certain ("positive") knowledge is based on natural phenomena and their properties and relations

Experiential realism

limit to admit the subjectivity
activity that is based on this subject / object scheme
interaction through our bodies with the world
the observation implies a more active
the perception itself influences in some way what is being observed
It is not possible to observe the world only objectively

Quantitative research

human knowledge
human conjectures

approach to reality as best they can.

post-positivism
experiential realism and pragmatism.
view of quantitative research
the world is seen as reality that can be empirically determined
results are based on larger sample sizes that are representative of the study group.
the research study can generally be replicated, simulated or repeated, due to its high reliability.
analyzes the information collected
Its purpose is to test whether a proposed study hypothesis is true or not.
specific research methodology gathering quantifiable data
using

computational techniques

mathematical

statistical

systematic investigation of a topic related to a social phenomenon
quantitative research

Epistemology

comes from the Greek word epistêmê
define knowledge
is the philosophy of knowledge
