# Data Analysis Task

A Data Analysis Task is an analysis task whose input is a dataset (to report constituent data patterns).

**Context:**- It can (often) be preceded by a Data Collection Task.
- It can be performed by a Data Analyst (and be described in a data analyst JD).
- It can range from being an Exploratory Data Analysis Task, to being a Confirmatory Data Analysis Task, to being a Functional Data Analysis.
- It can range from being a Categorical Data Analysis Task to being an Ordinal Data Analysis Task to being a Numerical Data Analysis Task.
- It can range from being a Univariate Data Analysis Task to being a Multivariate Data Analysis Task.
- It can range from being a Tabular Data Analysis Task to being a Multi-Relational Analysis Task (such as a graph analysis task).
- It can range from being a Small-Scale Data Analysis Task to being a Large-Scale Data Analysis Task.
- It can range from being a Batch Data Analytics Task to being an Interactive Data Analytics Task.
- It can range from being a Retrospective Data Analytics Task to being a Predictive Data Analytics Task.
- It can be solved by a Data Analysis System (that implements a data analysis algorithm).
- It can support Data Stewardship Tasks, Predictive Analytics Task.
- …

**Example(s):**- a Statistical Analysis, Machine Learning, Data Mining/Data Science, ...
- a Frequency Table Generation Task, Text Analysis Task, Timeseries Analysis Task, ...
- a Graph Analytics Task.
- a Data Volume Analysis.
- a Data Quality Analysis.
- a Workflow Analytics Task.
- a Domain-Specific Analytics Task, such as:
- a File Comparison Task.
- …

**Counter-Example(s):**- a Data Processing Task, such as data cleaning.
- Archeological Analysis.

**Analysis of data**is a process of inspecting, cleaning, transforming, and modeling data with the goal of discovering useful information, suggesting conclusions, and supporting decision making. 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 and CDA on confirming or falsifying existing hypotheses. Predictive analytics focuses on application of statistical or structural models for predictive forecasting or classification, while text analytics applies statistical, linguistic, and structural techniques to extract and classify information from textual sources, a species of unstructured data. All are varieties of data analysis.

Data integration is a precursor to data analysis, and data analysis is closely linked to data visualization and data dissemination. The term

*data analysis*is sometimes used as a synonym for data modeling.
