Chapter 2 Descriptive Statistics

Fazendo umas médias se faz uma média. Filipe Zabala

The descriptive statistics, is directly connected to the organization and description of the data. It brings together a reasonable amount of tools that can help in understanding observed values. It is used, for example, to assess how observations are distributed, where they are positioned and how they present themselves in terms of distribution and association.

In this chapter, concepts and methods of data exploration will be presented, a fundamental step for more advanced statistical analysis. For further discussion we recommend (Tukey 1977), a milestone in exploratory data analysis.
