Guidelines to write a research question
A research question states the aim of any research in form of a question. It is the thread necessary to structure the argument and make congruent the paper, project or thesis.
It should be detailed and focused so as to avoid the pitfalls of the common sense or general unanswerable subjects.
It should be feasible in so far as it should rely on accessible sources and follow a reasonable working plan.
It should be properly articulated with pertinent language and concepts.
It should be original inasmuch as the idea should be your own
In a half-page text you should pinpoint the relevance of the research question in relation to the scientific or public debate, postulate the expected results and be clear about the methodological steps.
