A non-directional research hypothesis is a kind of hypothesis that is used in testing statistical significance. It states that there is no difference between variables.
hypothesis
A hypothesis is a proposed explanation or prediction that is based on limited evidence and subject to further investigation. It serves as the starting point for scientific research and helps guide the design of experiments or studies. There are two main types of hypotheses: null and alternative. A null hypothesis states that there is no relationship or difference between variables, while an alternative hypothesis asserts that there is a relationship or difference between variables.
When a hypothesis is proven, it is no longer a hypothesis; a proven hypothesis is a theory.
When forming a hypothesis for quantitative research, a declarative hypothesis states the expected relation between variables, whereas a null hypothesis states that there is no significant relation.
The difference between the null hypothesis and the alternative hypothesis are on the sense of the tests. In statistical inference, the null hypothesis should be in a positive sense such in a sense, you are testing a hypothesis you are probably sure of. In other words, the null hypothesis must be the hypothesis you are almost sure of. Just an important note, that when you are doing a tests, you are testing if a certain event probably occurs at certain level of significance. The alternative hypothesis is the opposite one.
