i.e., an independent variable and adependent variable. If the hypothesis shows a relationship between the two parameters, the outcome could be due to an experimental or sampling error. However, if the null hypothesis returns false, there is a relationship in the measured phenomenon. ...
In this case, you are essentially trying to find support for the null hypothesis and you are opposed to the alternative. In conclusion finding a research hypothesis requires a scientific thinking about a certain problem that is going to be answered after doing the research. In recent years free...
