The null hypothesis usually states that there is no statistical significance between the two variables in the hypothesis.and is expressed as "There is no relationship between two quantities." A researcher aims to disprove it to demonstrate that there is a statistically- significant relationship between the two variables in the hypothesis. This is the basis of the success of the research study.
