Epistemological foundations of quantitative research

1. Refers to the term epistemology. When using a quantitative research approach.

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

Positivism

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

* 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.

Postmodernism

Postmodernism rejects the idea that science can be considered objective. It underlines the importance of subjective responses from individuals and communities.

* For postmodernists, research involves different ways of appreciating reality.

* There is no approved criterion on how to fit "quantitative research" and "qualitative research" to the taxonomy of the four paradigms.

Subjectivism

It is the doctrine that "our own mental activity is the only unquestionable fact of our experience", rather than shared or communal.

Subjectivism gives primacy to subjective experience as fundamental to all measures and laws.

Pospositivism

While positivists assume that finding truth is the ultimate goal of science

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.

Interpretationism

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.

Review

Criticism confronts those foundations and predictable knowledge methodologies, whether quantitative or qualitative, that make claims of scientific objectivit

* In addition, criticism differs from positivism and interpretivism.

* in the fact that this research philosophy aims to change existing and limiting social conditions, and not just predict or explain reality.

The main advantages of the quantitative approach.

1.The quantitative research approach is an investigation into a specific problem by applying an adopted scientific approach.

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

* 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.

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

* 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.

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.

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

Quantitative approach in educational generalities: some disadvantages of the quantitative approach

Quantitative research has advantages, but also some limitations.

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

Quantitative research is useful for segmentation of sample groups.

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 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.

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

* collecting data that has logical validity, which is a simple way to assess whether the study measures what it is supposed to measure.

* There are many advantages of using quantitative research that can be summarized mainly in four points.
