# Statistical Analysis

Statistics is the study of the collection, analysis, interpretation, presentation, and organization of data.[1] In applying statistics to, e.g., a scientific, industrial, or social problem, it is conventional to begin with a statistical population or a statistical model process to be studied. Populations can be diverse topics such as "all people living in a country" or "every atom composing a crystal". Statistics deals with all aspects of data including the planning of data collection in terms of the design of surveys and experiments.[1]

Statistical Analysis is an aspect of Data Analysis. In the context of Business Intelligence (BI), statistical analysis involves collecting and scrutinising every data sample in a set of items from which samples can be drawn. A sample, in statistics, is a representative selection drawn from a total population.

## Methods

Statistical analysis can be broken down into five discrete steps, as follows:

- Describe the nature of the data to be analyzed.
- Explore the relation of the data to the underlying population.
- Create a model to summarize understanding of how the data relates to the underlying population.
- Prove (or disprove) the validity of the model.
- Employ predictive analytics to run scenarios that will help guide future actions.
