Why is it necessary to have a research hypothesis in d presence of research question?

Hypothesis are tentative assumptions or intelligent guess to d solution of an identified problem. It is therefore necessary to be tested to help d researcher make decision on whether to reject or accept d null

It is necessary to have a research hypothesis in addition to a research question because a hypothesis provides a specific statement or prediction about the expected outcome of the research. While a research question helps to guide the inquiry and identify the topic of interest, a hypothesis offers a more focused and testable explanation or solution to the research question. It allows researchers to formulate clear expectations and predictions based on existing knowledge or theories, which can then be systematically tested through empirical research methods. In this way, a hypothesis serves as a crucial element in the scientific method by providing direction, structure, and a basis for evaluating the validity of research findings.
