A research problem is the statement which defines the research area and also gives a quick synopsis of how the hypothesis was arrived at. There are a number of things which you should consider before creating a research problem like first outline the general context of the problem. Then highlight the key theories, concepts and ideas. Underline the main assumptions of the area and highlight why these issues are identified important. After that determine what needs to be solved and also take into consideration the unanswered questions and controversies. By keeping all these things in mind, develop a research problem which should be precise, simple and clear.
The research process usually starts with a broad area of interest, the initial problem that the researcher wishes to study. It has to be narrowed down to one that can reasonably be studied in a research project. See more here
Observations are made, and the researcher decides on an area they would like to investigate. Within this area, the researcher must think about which aspect will give useful knowledge, and they research this. Often, it is a problem where the outcome will be of use other than just knowledge, it could be used in medecine, conservation etc. But ofcourse, when deciding what to research, the researcher must make sure the y consider wether or not the research is likely to prove the hypothesis or not.If the idea is obviously going to end up being wrong, then there is no need to research it.
