In descriptive statistics, **summary statistics** are used to summarize a set of observations, in order to communicate the largest amount as simply as possible. Statisticians commonly try to describe the observations in

- a measure of location, or central tendency, such as the arithmetic mean
- a measure of statistical dispersion like the standard deviation
- a measure of the shape of the distribution like skewness or kurtosis
- if more than one variable is measured, a measure of statistical dependence such as a correlation coefficient

A common collection of order statistics used as summary statistics are the five-number summary, sometimes extended to a seven-number summary, and the associated box plot.

Entries in an analysis of variance table can also be regarded as summary statistics.

### Famous quotes containing the words statistics and/or summary:

“We ask for no *statistics* of the killed,

For nothing political impinges on

This single casualty, or all those gone,

Missing or healing, sinking or dispersed,

Hundreds of thousands counted, millions lost.”

—Karl Shapiro (b. 1913)

“I have simplified my politics into an utter detestation of all existing governments; and, as it is the shortest and most agreeable and *summary* feeling imaginable, the first moment of an universal republic would convert me into an advocate for single and uncontradicted despotism. The fact is, riches are power, and poverty is slavery all over the earth, and one sort of establishment is no better, nor worse, for a people than another.”

—George Gordon Noel Byron (1788–1824)
