Statistics plays an important role in the description
of mass phenomena. It offers methods to summarize a collection of data.
These methods may be numerical or graphical, both of which have their own
advantages and disadvantages. Graphical methods are better suited for the
recognition of patterns in the data, whereas numerical methods give well-defined
measures of some properties. In general, it is recommended to use both
approaches for the description of data.
A field which is closely related to descriptive statistics,
is exploratory data analysis.
