When we write a systematic literature review, we look for some potential research questions to explore, how many questions we can have? Can we have only one research questions?
There are no formal rules on this. However, you don't want to make the systematic review too complicated by having too many unrelated (or related) research questions. I could see a systematic review having two, maybe three, closely related research questions. Assuming that you eventually want to publish this systematic review, you don't want to overload your reader with too many research questions. Keep it simple! The number of research questions you choose to have may depend on the number of studies you find that meet your study eligibility criteria for your research question(s). For example, if I don't find many (i.e.,
Thank you Proloy Barua and Gordon L Warren Sir, for your kind response.
It means I should have sufficient number of literature/studies to address the question in consideration, and then I shall keep that as a research question in our proposed review, right? And with one RQ , I can lead a SLR article, ?
The number of research questions in a systematic review depends on the topic of research and its unexplored issues. It is also depend on focus of the study that on what depth you want to cover your study. But in general I believe minimum 4-5 research questions which could cover a broad area of the topic and might be related also, should be there .
It depends on your research objectives to conduct the SLR. First, be focused on your objectives and design your research questions. I can refer to some following SLRs for your reference.
