Statistics is branch of mathematics dealing with the collection, analysis, interpretation, presentation, and organization of data. It is used to solve scientific, industrial, or social problems.
A standard statistical procedure involves the test of the relationship between two statistical data sets, or a data set and synthetic data drawn from an idealized model. A hypothesis is proposed for the statistical relationship between the two data sets, and this is compared as an alternative to an idealized null hypothesis of no relationship between two data sets.
