Data are collected and analyzed to answer questions, test hypotheses or disprove theories.

Data mining is a particular data analysis technique that focuses on modeling and knowledge discovery for predictive rather than purely descriptive purposes, while business intelligence covers data analysis that relies heavily on aggregation, focusing mainly on business information.Textual data spell checkers can be used to lessen the amount of mistyped words, but it is harder to tell if the words themselves are correct.The process of exploration may result in additional data cleaning or additional requests for data, so these activities may be iterative in nature.Mathematical formulas or models called algorithms may be applied to the data to identify relationships among the variables, such as correlation or causation.In general terms, models may be developed to evaluate a particular variable in the data based on other variable(s) in the data, with some residual error depending on model accuracy (i.e., Data = Model Error).
