Let's say we do a research whose hypothesis is "X is related to Y". Also, similar studies are supporting this hypothesis. Therefore the null hypothesis is going to be "X is not related to Y". So, the research objective is to prove that the null hypothesis is wrong. But during my research, the things went in such a way that I was able to prove and find evidences that the hypothesis is actually wrong. Is this normal? Does it cause any problem with the research structure?
