CEVAP:

The researcher who struggles to limit the issue of research should first identify a “problem statement” that sets out the purpose of the research. The “problem statement” should be simple, clear, and questionable, as well as being restrictive. What the researcher will search for, in other words, which idea will be defended, will find its expression in the problem. The problem statement tells the truth that the researcher will defend in her/his research, test the truth, or reveal the cause-effect relations. If a researcher finds the opportunity to go into the subject and evaluate a large number of sources, the problem statement may change.
