Epistemological foundations of quantitative research

The text explores different epistemological foundations in research methodologies, contrasting quantitative and qualitative approaches. It delves into positivism, a theory that bases knowledge on natural phenomena and emphasizes objective, measurable results from large sample sizes.

Epistemological foundations of quantitative research

The main advantages of the quantitative approach.

Furthermore, employing the quantitative research approach is essentially recommended as it is reasonably easy to conduct a research study.

* There are many advantages of using quantitative research that can be summarized mainly in four points.
* collecting data that has logical validity, which is a simple way to assess whether the study measures what it is supposed to measure.

Quantitative research is practical and useful because it is likely that ...

The data collection methods, as well as the way they are analyzed using statistics, not only save time, but also reduce the waste of resources.
The results achieved are statistical. In conclusion, the quantitative approach is suitable to answer more precisely some fundamental questions for data analysis such as who, how much, what, where, when, how many and how.

* For example, to measure an aspect of interest in a research study using numbers.

It is also useful for verifying the data obtained or for explaining some phenomena with the help of many statistical techniques that have been developed "to make researchers predict scores on a factor or variable."
Quantitative research is useful for segmentation of sample groups.

Finally, quantitative research is primarily objective and appropriate for hypothesis testing, and the results are valid, reliable, and generalizable to a broader population.

Quantitative research has advantages, but also some limitations.

A second limitation is that the positivism paradigm does not describe how reality is "formed" nor does it refer to how people "interpret" their behaviors.

When conducting quantitative research, some errors can occur if a hypothesis or method for collecting and analyzing data is not developed accurately, which can cause invalidation of the results.
* Depending on the results found, it will be easier to figure out which statistical tests can be used to make such an analysis with greater precision to avoid errors and subjectivity.

* The use of statistical data for explanations and analysis of the investigation has significant advantages in the investigation process because the information can be verified, confirmed and verified with greater precision.

* In addition, the quantitative approach helps investigations to optimize the time and effort invested in analyzing and describing the results obtained.

* allows you to observe, count and analyze the required information using statistical techniques.

Review

Criticism confronts those foundations and predictable knowledge methodologies, whether quantitative or qualitative, that make claims of scientific objectivit
* in the fact that this research philosophy aims to change existing and limiting social conditions, and not just predict or explain reality.
* In addition, criticism differs from positivism and interpretivism.

Interpretativeism has a strong critical position towards positivism underlying qualitative analysis over quantitative analysis.

Interpretativeism, whose focus is on meaning, is used "to group different approaches" to reveal different characteristics of the subject of study.

Interpretationism

Pospositivism

postpositivist critical realists believe that the goal of science is to faithfully achieve the goal of obtaining information about reality, since all measurement is imperfect.
While positivists assume that finding truth is the ultimate goal of science

Subjectivism

Subjectivism gives primacy to subjective experience as fundamental to all measures and laws.
It is the doctrine that "our own mental activity is the only unquestionable fact of our experience", rather than shared or communal.

Postmodernism

Postmodernism rejects the idea that science can be considered objective. It underlines the importance of subjective responses from individuals and communities.
* There is no approved criterion on how to fit "quantitative research" and "qualitative research" to the taxonomy of the four paradigms.
* For postmodernists, research involves different ways of appreciating reality.

* Information derived from sensory experience, interpreted through reason and logic, constitutes the exclusive source of all knowledge.

Positivism holds that valid knowledge (certainty or truth) is found only in this a posteriori knowledge.

* It is a philosophical theory that affirms that certain knowledge ("positive") is based on natural phenomena.

Positivism

* Results are based on larger sample sizes that are representative of the study group.
