| Statistics Dictionary: statistic |
A function of the set of random variables corresponding to a set of observations. Often used to refer to the corresponding function of the data. The word 'statistic' was introduced by Sir Ronald Fisher in 1922. Two simple examples are the sample mean and the coefficient of correlation.
| Accounting Dictionary: Statistic |
Numerical characteristic of a sample (taken from a population) computed using only the elements of a sample of the population. For example, the mean and the mode are statistics of the sample.
| Dental Dictionary: statistic |
Any value or number that describes a series of quantitative observations or measures; a value calculated from a sample.
| Sports Science and Medicine: statistic |
A single piece of information capable of exact numerical representation, such as the arithmetic mean of a sample.
| Veterinary Dictionary: statistic |
A numerical value calculated from a number of observations in order to summarize them.
| Wikipedia: Statistic |
A statistic (singular) is the result of applying a function (statistical algorithm) to a set of data.
More formally, statistical theory defines a statistic as a function of a sample where the function itself is independent of the sample's distribution: the term is used both for the function and for the value of the function on a given sample.
A statistic is distinct from an unknown statistical parameter, which is not computable from a sample. A statistic used to estimate a parameter is called an estimator. For instance, the sample mean is a statistic and an estimator for the population mean, which is a parameter.

In the calculation of the arithmetic mean, for example, the algorithm consists of summing all the data values and dividing this sum by the number of data items. Thus the arithmetic mean is a statistic, which is frequently used as an estimator for the generally unobservable population mean parameter.
Other examples of statistics include
A statistic is an observable random variable, which differentiates it from a parameter, a generally unobservable quantity[1] describing a property of a statistical population.
Statisticians often contemplate a parameterized family of probability distributions, any member of which could be the distribution of some measurable aspect of each member of a population, from which a sample is drawn randomly. For example, the parameter may be the average height of 25-year-old men in North America. The height of the members of a sample of 100 such men are measured; the average of those 100 numbers is a statistic. The average of the heights of all members of the population is not a statistic unless that has somehow also been ascertained (such as by measuring every member of the population). The average height of all (in the sense of genetically possible) 25-year-old North American men is a parameter and not a statistic.
Important potential properties of statistics include completeness, consistency, sufficiency, unbiasedness, minimum mean square error, low variance, robustness, and computational convenience.
