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
