Answer:
A hypothesis must be testable for it to be useful in scientific research.
Explanation:
In a scientific research, the researcher needs to stipulate a hypothesis to be tested. Then he or she will do the work based on this assumption, which can be confirmed or rejected at the end of the job. This confirmation or rejection of the hypothesis will be obtained through the result of the analysis, either through data, literature review or experiment.
For example, an economist will do research on the impact of rising incomes on decreasing mortality. He may have a hypothesis that increased income has a positive effect on life expectancy. Then he will do the data analysis and in the end he will know if his hypothesis has been accepted or rejected.
