# What is the Meaning of: Statistics | Concept and Definition of: Statistics

The statistical term comes from the latin statisticum collegium ("Council of State") and its derivative Italian statista ("man of State or politician"). In 1749, German Gottfried Achenwall began to use the word German statistik for the analysis of State data. However, administrative government and its bodies are at the origin of the statistics.
Today, we can say that the gathering and interpretation of the data obtained in a study is the task of statistics, which is considered a branch of mathematics. Statistics (the result of applying a statistical algorithm to a DataSet) allow the decision-making within the Government framework, but also in the world of business and commerce.
Applied statistics can be divided into two branches: the descriptive statistics (it concerns methods for collecting, description, display and the summary data that can be presented in the form of numbers or graphs) and statistical inference (generation models and predictions about the phenomena studied, taking into account the randomness and uncertainty in the observations).
In addition to applied statistics, there is also a mathematical statistical called discipline, which includes the theoretical bases of the material.
With regard to the statistics-mathematics methods, they are have arisen following the theory of probabilities, which calculates the frequency at which takes place a result in an experimentation under sufficiently stable conditions.
Nowadays, statistical practices have made progress and have improved through the establishment of specific instruments that allow to implement public policies.
