This requires one to identify and consequently to draw a connection between the variables identified as essential to the research subject. For instance, if one determines to research the subject of the legal status of abortion, it would not be considered analytical to simply report that "Abortion is a highly controversial issue in Australian society." An analytical hypothesis might instead make the argument that "Abortion laws remain highly debated in Australia because the national government has not sufficiently defined a universal legal position on the subject." The latter hypothesis provides the grounding for a research proposal where one can identify dependent and independent variables, where one can presume the presence of certain relationships and where one can consequently suggest a research design that might prove...

Ultimately, this helps us to understand the research proposal as something of a reference to be used by the author as the research process ensues. Following approval, this can become a useful instrument for bringing focus to the purpose and aims of a research endeavor.
That said, it is also of value to note that the research proposal is not carved in stone. Many of the initial presumptions of the research or the strategies presumed to be appropriate at the outset will have changed over the course of a literature review, a gathering of resources, data collection or practical execution of research. At any step, the researcher may find that it is expedient or necessary to adapt some of the ideas expressed in the proposal. This is normal and permissible. But even in these instances, the research proposal remains a centering document from which all others will ultimately proceed.
