In descriptive statistics, summary statistics are used to summarize a set of observations, in order to communicate the largest amount of information as simply as possible.
A descriptive statistic (in the count noun sense) is a summary statistic that quantitatively describes or summarizes features of a collection of information, while descriptive statistics in the mass noun sense is the process of using and analyzing those statistics.

Seven-number summary

Bowley's seven-figure summaryseven-figure summary
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.
In descriptive statistics, the seven-number summary is a collection of seven summary statistics, and is an extension of the five-number summary.

Median

averagesample medianmedian-unbiased estimator
Common measures of location, or central tendency, are the arithmetic mean, median, mode, and interquartile mean.
The median is a popular summary statistic used in descriptive statistics, since it is simple to understand and easy to calculate, while also giving a measure that is more robust in the presence of outlier values than is the mean.

Arithmetic mean
