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.</SPAN></P><P><SPAN style="font-family: 'Calibri','sans-serif';">More formally, statistical theory defines a statistic as a function of a sample where the function itself is independent of the sample's distribution; that is, the function can be stated before realization of the data. The term statistic is used both for the function and for the value of the function on a given sample.</SPAN></P><P><SPAN style="font-family: 'Calibri','sans-serif';">A statistic is distinct from a statistical parameter, which is not computable because often the population is much too large to examine and measure all its items. However, a statistic, when used to estimate a population parameter, is called an estimator. For instance, the <EM>sample mean</EM> is a statistic that estimates the <EM>population mean</EM>, which is a parameter.</SPAN></P><P></P><P><SPAN style="font-family: 'Calibri','sans-serif';">It might take time to understand but be patient with yourself.</SPAN></P><P></P><P><SPAN style="font-family: 'Calibri','sans-serif';">Regards,</SPAN></P><P><SPAN style="font-family: 'Calibri','sans-serif';">Gabriel<BR /></SPAN></P></BODY></HTML> Mon, 25 Mar 2013 10:37:45 GMT https://community.qlik.com/t5/QlikView/help/m-p/386676#M144420 Gabriel 2013-03-25T10:37:45Z
