If your hypothesis is not supported by your data, the best course of action is to rethink your original hypothesis. This approach involves examining the underlying assumptions and considering if your hypothesis needs to be modified, refined, or even discarded based on the evidence you have gathered.
The other options—changing variables to support the hypothesis, altering the way data is presented, or changing the data itself—would compromise the integrity of the research and scientific process. It's important to prioritize integrity and objectivity in research, allowing data to inform conclusions.
