In mathematics, the purpose of descriptive statistics is to describe the properties of data samples and measurements in a simpler way. It forms part of quantitative data analysis in statistics.
In descriptive statistics, no conclusions can be drawn nor a hypothesis be proven regarding a set of quantitative data. It differs from inferential statistics where deductions are formulated that go beyond the scope of the data presented. Descriptive statistics is merely the manner of conveying numerical information in a simpler form where possible data patterns can be obtained. The tools used in descriptive statistics are charts and graphs for graphical description, tables for tabulated description and discussions for statistical commentary.
