A hypothesis becomes a theory when it holds true over time when verified against facts and is created via the scientific method.
<h3>
What is the hypothesis?</h3>
A hypothesis is a tested assertion about the relationship between two or more variables or a theory put up to explain an observed occurrence in a scientific environment. The hypothesis is a succinct statement of the researcher's expectation of the study's findings, which may or may not be confirmed by the results, in a scientific experiment or study. The scientific method's fundamental step is hypothesis testing.
It is customary to refer to the researcher's prediction as the alternative hypothesis and any other result as the null hypothesis, or, more simply put, the opposite of what was anticipated. (However, the phrases are flipped if the researchers are speculating that there won't be any difference or change, speculating, for instance, that the incidence of one variable won't increase or decrease in tandem with the other. The ability for a proposition to be shown to be incorrect, which certain schools of thought deem crucial to the scientific method, is met by the null hypothesis. Others, however, contend that testability is sufficient because it is not required to be able to imagine a scenario in which the hypothesis would be incorrect.
