'''Data analysis''' is the [[analysis]] of [[data]].

== Description ==

Analysis of data is:

* A process of inspecting, cleaning, transforming, and [[Data model|modeling data]]
* With the goal of discovering useful information, suggesting conclusions, and supporting decision-making

The term ''data analysis'' is sometimes used as a synonym for [[data modeling]].

Data analysis has multiple facets and approaches, encompassing diverse techniques under a variety of names, in different business, science, and social science domains.

[[Data mining]] is a particular data analysis technique that focuses on modeling and knowledge discovery for predictive rather than purely descriptive purposes.

[[Business intelligence]] covers data analysis that relies heavily on aggregation, focusing on business information.

In statistical applications, some people divide data analysis into [[descriptive statistics]], [[exploratory data analysis]] (EDA), and [[confirmatory data analysis]] (CDA).

* EDA focuses on discovering new features in the data
* CDA focuses on confirming or falsifying existing hypotheses

[[Predictive analytics]] focuses on application of [[Statistical model|statistical models]] for predictive forecasting or classification.

[[Text analytics]] applies statistical, linguistic, and structural techniques to extract and classify information from [[textual sources]], a species of [[unstructured data]].

[[Data integration]] is a precursor to data analysis, and data analysis is closely linked to [[data visualization]] and [[data dissemination]]..
