There are some major criteria that decides differences between quantitative vs qualitative research for detailed information on it go through following lecture ->

Types of Research (Qualitative Vs Quantitative)

Qualitative research has more inclination or focuses more on understanding subjective expertise of individuals.

Qualitative Research focuses more on objective data and analysis.

Qualitative research involves collecting and analyzing non-numerical data (e.g., text, video, or audio) to understand concepts, opinions, or experiences. It can be used to gather in-depth insights into a problem or generate new ideas for research.

Quantitative research involves collecting and analyzing numerical data. It is ideal for identifying trends and averages, making predictions, testing relationships, and generalizing results for large populations.

Harold Shangali "Qualitative research has more inclination or focuses more on understanding subjective expertise of individuals.

Qualitative Research focuses more on objective data and analysis."

In my perspective, that is a myth: there is nothing like quantitative or qualitative research. What exists is a set of different traditions, orientations or intentions in research and scientific inquiry, as stated by Jurgen Habermas: those interested on explanation, those interested in interperetation and comprehension, and those interested in transformation. And, in modern terms, what is most used is a combination of research design and techniques which let us to pursue answers to research questions in a coherent and scientific community accepted way, regarless of particular characterístics of their strategies or techniques.

Therefore, in modern projects is usual to mix many of the techniques, design and analyses. And, in that perspective, to speak about quantitative or qualitative research: 1) does not reflect the real research work, and 2) pretends to define kinds of research based just on some analysis techniques, which has almost a nonsense.

sorry but "my perspective" means nothing no matter who it comes from and that is what is nonsense. . science is not subjective or anyone opinion or "perspective" neither is research methodology. here are some current textbooks from one of the best publishers in the business. https://us.sagepub.com/en-us/nam/product/qualitative%20research

Dear Mary-Helen Castanuela :

If you read, you can see that I´m being modest, becuse I recognize that there are other perspectives and developments, different from thae one that I am defending. And I'm being honest, because my experience in research work taught me something different that manuals usually say. That's all.

By the way, this perspective has support in research work also. Here is an article on that:

perspective means point of view so sorry but research and science is NOT point of view-- imagine where we would be of not be if every researcher and scientist had their own pov/perspective-- frankly there would be no science

Dear Mary-Helen Castanuela

When I was saying "point of view", I was meaning an argument grounded on scientific evidence or, at least, acknowledged academic perspectives.

It is completely different and contrary to your reference to non-grounded opinions, which clearly I am not referring. And, please, read in a complete way: at the end, there is a link to an article, authored by a long-term researcher, on the point I am talnking about.

Thanks.

u said "perspective" which does not mean "argument grounded on scientific evidence" please

i am through ere since it is getting nonsensical and i don't have time for such

Back to the question asked by Rahul Jain : can we say that "quantiative research" and "qualitative research" is a good way to clasify the possible kinds of research and scientific inquiry?

I think this is the point. And, looking to research done and published in journals and different formats, it is difficult to identify them in a way that we can say they are clearly "quantitative" or "qualitative". What do you think about it and why?

Quantitative is the dictatorship and traditional way of undertaking research while qualitative approach is struggling to break the new grounds.

I'm not sure whether anyone has written that a research project can be both quantitative and qualitative.

Usually, the numbers of people being researched are higher in quantitative research.

My PhD research and follow-ups 'living with faecal incontinence' used constructivist grounded theory; very qualitative.

It was just right for what I needed for my project.

See pp130-131.

Quantitative research is numbers-driven, and all data is coded and can be statistically analyzed and compared. Qualitative research usually precedes quantitative research in that theories of relationships are first approached. The subject of qualitative research is less quantifiable, such as emotionality, for example, "How strongly do you feel about something?" This qualitative statement can be quantified using a scale of 1 to 7 or 0 to 10. But the numbers are not necessarily accurate because they are essentially qualitative. On the other hand, Quantitative measures would involve the temperature of a chemical reaction and the height of men who enlist for active wartime duty. Quantitative and qualitative measurements derive from the data we are measuring, and the statistical processes are different because the numbers describe more or less accurately what is being measured.

It can be mixed either qualitative first and then quantitative and vice versa.

Qualitative research as to do with trying to understand respondent perception about a particular focus of study. Meaning is open ended in nature. While the quantitative research is restricted to the researcher line of design. It is closed ended in nature and number driven.

A very basic answer is that qualitative research deals with what people say, while quantitative research deals with the numbers of people who say 'whatever'.

Qualitative research is a research method that involves collecting and analyzing non-numerical data such as text, images, and sounds. Quantitative research is a research method that involves collecting and analyzing numerical data.
