In the manufacturing world, you can make as much as anything you want. If it is all garbage no one is going to buy it. You learn how to make quality products firs,t so people will buy them. Then you worry about making as many as you can. Same with research, if you put out a bunch of info no one care about no one will read it.
The reason I think that quantative research is better than qualitative research is because the former is all about precise and mathematical strategies to an issue. The latter is about more of a social approach, which can be hindered by many different variables. I think that when there are less objectivity, the better.
If you look at qualitative only, you will be prone to bias, situating your aim, fulfilling your desired finding rather than the reality. Quantitative methods allow you to distill ideas down to comparable entities, which greatly assists in parsing out truth from lies.
This seems to be the flaw in the social sciences, currently. They focus too much on qualitative, and ignore quantitative, so can't actually quantify the gravity/ prevalence of issues they see, regardless of whether or not their idea is valid to begin with.
Meanwhile, the hard sciences seem to strike the balance, particularly in looking at value judgments in engineering, assessing utility and effectiveness, cost benefit and the like. Without qualitative methods, science is just math, really, with no direct application.
Finding a characteristic of something is important but, finding exact numbers can be more beneficial for many things. If NASA is wanting to dock something onto the ISS, then they will have to have very precise calculations to be able to dock whatever they want on there without causing any harm to the ISS. But overall both are a major part of research in general and should be thought as such.
Qualitative research is in no way, shape or form better than quantitative research. Quantitative research is the one that produces actual evidence for their claims while qualitative does not. This is the main reason why it is better, because you can actually see and feel what come of the research.
No, qualitative research is not better than quantitative research, because both are necessary in different context. Certainly, the quality of research is extremely important, as well as having defined goals for a specific research task. But quantitative research is important too, when a large volume of work is critical to answering problems.
