There is also a discipline calledВ mathematical statisticsВ that studies statistics mathematically.The wordВ statistics, when referring to the scientific discipline, is singular, as in 'Statistics is an art.В This should not be confused with the wordВ statistic, referring to a quantity (such asВ meanВ ormedian) calculated from a set of data,В whose plural isВ statisticsВ ('this statistic seems wrong' or 'these statistics are misleading').Дescriptive Statistics:Methods of organizing, summarizing andpresenting data in an informative way.Inferential Statistics:Methods used to estimate a property of apopulation on the basis of a sample. Such people have often gained this experience through working in any of aВ wide number of fields.

It deals with all aspects of this, including the planning of data collection in terms of the design ofВ surveysВ andВ experiments.AВ statisticianВ is someone who is particularly well versed in the ways of thinking necessary for the successful application of statistical analysis. StatisticsВ is the study of the collection, organization, analysis, interpretation, and presentation ofВ data.
