is a single measure of some attribute of a sample (e.g., its arithmetic mean value). It is calculated by applying a function (statistical algorithm) to the values of the items of the sample, which are known together as 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.<br /> <br /> == Definition ==<br /> <br /> In applied statistics, a statistic is any quantity computed from values in a sample that is part of a collection of statistics. A statistic is a random variable that is a function of the random sample, but not a function of unknown parameters. The probability distribution of the statistic, though, may depend on the unknown parameters.<br /> <br /> == Types of statistics ==<br /> <br /> There are two types of statistics in data analysis:<br /> <br /> # &#039;&#039;&#039;[[Descriptive statistics]]&#039;&#039;&#039;: This type of statistics involves methods of organizing, picturing and summarizing information from data. Descriptive statistics are merely used to describe what&#039;s going on in the data. <br /> <br /> # &#039;&#039;&#039;[[Inferential statistics]]&#039;&#039;&#039;: Inferential statistics involves methods to generalize and make decisions or predictions about a population based on a sample of data taken from the population in question.<br /> <br /> == Statistical theory ==<br /> <br /> &#039;&#039;&#039;[[Statistical theory]]&#039;&#039;&#039; comprises the body of principles underlying the collection and analysis of data. In it, the term &quot;statistical&quot; is used to mean &quot;pertaining to data sets.&quot;<br /> <br /> == See also ==<br /> <br /> * [[Data]]<br /> * [[Data analysis]]<br /> * [[Data collection]]<br /> * [[Data set]]<br /> * [[Sample (statistics)]]<br /> * [[Population (statistics)]]<br /> <br /> == References ==<br /> <br /> &lt;references /&gt;<br /> <br /> [[Category:Statistics]]<br /> [[Category:Mathematical and quantitative methods (economics)]]<br /> [[Category:Mathematical science occupations]]<br /> [[Category:Applied mathematics]]<br /> [[Category:Formal sciences]]<br /> <br /> {{stub}}</div> Prab
