Discussing the problem with the colleagues, or the professional researchers about the problem under investigation.Examining the available data concerned with the problem.Reviewing the similar studies and literature related to a similar problem.Following are some of the main sources of the hypothesis that may help the researcher to formulate a good hypothesis. The data collection for the hypothesis formulation refers to the review of literature related to the concerned topic, and understanding of the previous research on the related topic.
