In your dissertation, you may create a hypothesis based on your research that predicts a relationship, called an "alternative" or "research" hypothesis.
To balance your findings, you will also create a "null" hypothesis, which claims that the relationship that is to be proven in the research hypothesis does not exist.

A hypothesis (plural hypotheses) is a precise, testable statement of what the researchers predict will be the outcome of the study.
This usually involves proposing a possible relationship between two variables: the independent variable (what the researcher changes) and the dependent variable (what the research measures).An aim identifies the purpose of the investigation.It is a straightforward expression of what the researcher is trying to find out from conducting an investigation.Research Methods Knowledge Base states that hypothesis testing assumes that both mutually exclusive hypotheses (research and null) exhaust every possible outcome and in the end, one is accepted and the other is rejected. When you analyze your data, you conclude whether you reject your null hypothesis and accept your alternative or fail to reject your null. This usually involves proposing a possible relationship between two variables: the independent variable (what the researcher changes) and the dependant variable (what the research measures).Although you could state a scientific hypothesis in various ways, most hypotheses are either "If, then" statements or else forms of the null hypothesis.Surely the alternative (or experimental) hypothesis is more important? However, we can never 100% prove the alternative hypothesis.What we do instead is see if we can disprove, or reject, the null hypothesis.It states that the results are not due to chance and that they are significant in terms of supporting the theory being investigated.The null hypothesis states that there is no relationship between the two variables being studied (one variable does not affect the other).
