Information: Many more- and to orders (km, number of visitors). “” Communications: we have only 17 chairs! “I get the missing 3 chairs!” Statistics is the study of methods to deal with quantitative information (data). It is an opportunity to establish a systematic connection between experience (empiricism) and theory”.

It is among other things the summary of certain methods to analyze empirical data. Statistics is considered as a mathematical discipline through the collection, analysis, interpretation or presentation of data… The statistics will be in the following three parts divided: the d eskriptive statistics (also descriptive statistics or empirical statistics): this data are described in an appropriate manner, processed, and summarized. One compacted quantitative data to tables, graphics and figures with their methods. … The inductive statistics (also mathematical statistics, inferential statistics or statistical inference): Inductive statistics analysis to properties of the population from the data of a sample.

The exploratory statistics (also hypotheses-generating statistics, analytical statistics or data mining): This is an intermediate form of the two aforementioned areas methodically, but increasingly gets independent significance as application form. By means of descriptive procedures and inductive methods of test searches she systematically possible links (or differences) between data in existing databases and to assess at the same time in their strength and earnings security. The as-found results can be understood as hypotheses, the only, after that anabolic, inductive test procedure with appropriate (prospective) test plans confirmed they can considered statistically backed up. The difference between descriptive and explorative statistics is evident also in the issues: descriptive statistics: How can one describe a distribution of characteristic? Exploratory statistics: what is a distribution of a characteristic noteworthy or unusual? A collection of (often survey) carried out in the laboratory or in the field refers to empirical (experience, knowledge”) in the science of information, running investigations based on targeted, systematic.
