Research the meaning of null hypothesis. Describe how and why it is used in experimental design. Properly cite your reference. In statistical inference of observed data of a scientific experiment, the null hypothesis refers to a general or default position: that there is no relationship between two measured phenomena,[1] or that a potential medical treatment has no effect.[2] Rejecting or disproving the null hypothesis ? and thus concluding that there are grounds for believing that there is a relationship between two phenomena or that a potential treatment has a measurable effect ? is a central task in the modern practice of science, and gives a precise sense in which a claim is capable of being proven false.
