The practice of science involves formulating and testing hypotheses, assertions that are capable of being proven false using a test of observed data. The null hypothesis typically corresponds to a general or default position. For example, the null hypothesis might be that there is no relationship between two measured phenomena or that a potential treatment has no effect. In most legal systems, the presumption that a defendant is innocent ("until proven guilty") can be interpreted as saying that the null hypothesis is that the defendant is innocent.
