Help with Statistic homework

A statistic is defined as a sole measure of some characteristic of a sample that may include its arithmetic value. It can be calculated by relating a function to the standards of the things of the model, which are collectively known as data set.

To be more formal, statistical concept describes a statistic as a function of an example where the function itself is not dependent on the sample's delivery; which means that the function can be specified prior to recognition of the data. The word statistic is applied both for the function and for the importance of the function on a provided data or sample.

A statistic is discrete from a statistical factor, which is not calculable because frequently the population is too much large to be examined and measure all its matters. Conversely, a statistic, when try to guess a population limit, is known an estimator.

Whenever statistic is being applied for a detailed purpose, it may be denoted by a term specifying its purpose: as in estimation theory, an estimator is meant to guess a limit of the delivery, descriptive form of statistic is used to define the data; in statistical hypothesis checking, a test statistic is meant to check a theory. Although, a sole statistic can be used for numerous purposes; for instance the model mean can be applied to define a data set, to evaluate the population mean, or to asses a theory.
