Statistics (from German: Statistik , orig. "description of a state, a
country") is the discipline that concerns the collection, organization,
analysis, interpretation, and presentation of data. In applying statistics to
a scientific, industrial, or social problem, it is conventional to begin with
a statistical population or a statistical model to be studied. Populations can
be diverse groups of people or objects such as "all people living in a
country" or "every atom composing a crystal". Statistics deals with every
aspect of data, including the planning of data collection in terms of the
design of surveys and experiments.
