If researchers don't take the time or trouble to isolate the lesser problems within the major problem, their research projects become cumbersome and unwieldy. Research is guided by the specific research problem, question, or hypothesis. Having stated the problem and the attendant subproblems, each subproblem is then viewed through a construct called a hypothesis. A hypothesis is a logical supposition, a reasonable guess, an educated conjecture. It may direct your thinking to the possible source of information that will aid in resolving the research problem through the resolution of each attendant subproblem.
Hypotheses are nothing new.
They are constant, recurring features of everyday life. They represent the natural working of the human mind. Immediately, you attempt to account for the cause of the happening by constructing a series of reasonable guesses. In, research, assumptions are equivalent to axioms in geometry self-evident truths. The assumption must be valid or else the research cannot proceed.
