Why can’t we directly test the research hypothesis?
What will be an ideal response?
Ans: One study can only provide evidence in support of a research hypothesis but never prove it to be true. If data analysis shows a meaningful effect, the effect is true based on the precise method we chose and the exact way we defined our variables. We cannot know if every approach to studying the research hypothesis would yield a significant outcome. The best we can do with a significant outcome is say we reject the null hypothesis in favor of the research hypothesis. Together with other studies, we can build evidence for a research hypothesis and ultimately create a foundation for a theory.
