It can be any hypothesis that is processed for work during the research. The figure on the right illustrates this two-tailed prediction for this case.

Well fragmented hypotheses indicate that the researcher has adequate knowledge in that particular area and is thus able to take the investigation further because they can use a much more systematic system.

A hypothesis is a tentative answer to a research problem that is advanced so that it can be tested. But for a researcher hypothesis is a formal question that he intends to resolve.
