The origin of statistics can be traced back to the primitive man, who put notches on trees to keep an account of his belongings. During 5000 BCE, kings used to carry out census of populations and resources of the state. Kings of olden days made their crucial decisions on wars, based on statistics of infantry, and elephantary units of their own and that of their enemies. Later it enhanced its scope in their kingdoms’ tax management and administrative domains. Thus, the word ‘Statistics’ has its root either to Latin word ‘Status’ or Italian word ‘Statista’ or German word ‘Statistik’ each of which means a ‘political state’. The word ‘Statistics’ was primarily associated with the presentation of facts and  figures pertaining to demographic, social and political situations prevailing in a state/government. Its evolution over time formed the basis for most of the science and art disciplines. Statistics is used in the developmental phases of both theoretical and applied areas, encompassing the field of Industry, Agriculture, Medicine, Sports and Business analytics.

* Derived from Latin statisticum collegium (“council of state”)

• Italian word statista (“statesman” or “politician”)
• German book Statistik, published in 1749, described the analysis of demographic and economic data about the state (political arithmetic in English)
• Was broadened in 1800s to include the collection, summary, and analysis of data of any type; also was conjoined with probability for the purpose of statistical inference.
