The availability of subjects is an external criterion in the selection of the research problem
Research problem is a part of a research where the researcher writes the problems being talked about in their research. Basically, the research is the result of the investigation addressing the problem.
There are few things to be considered while deciding the research problem of a research. Several of them are the scope of the researcher's interest, the information regarding the problem, as well as getting feedbacks from the supervisors.
Meanwhile, during the process of deciding the research problem, there is a certain criteria that will influence the researcher's writing progress. As mentioned in the original question, those are an external and internal criterion.
To name a few, as per the question:
- Time factor. The time being referred here is definitely the researcher's. It is up to the researcher whether they would allocate weeks, months, and even years according to their availability. And, this one is called an internal criterion because it only depends on the researcher.
- Cost and returns. This is similar to the previous criterion. If the researcher does not acquire funding for their research, then they should use their own money, thus making this one an internal criterion.
- In contrast, the mention of subjects in this choice refers to the research's subjects. They must be people or things outside the researcher, and are regarded as an external criterion due to the researcher not having the power to control their availability.
- Lastly, the interest of the researcher makes up the last example of internal criterion in the process of deciding research problems. The reason why this is included in an internal criterion is that because it depends on the researcher themselves. Other aspects might influence the researcher's interest, but ultimately it is the researcher's decision that define the research problems.
