Resumen del libro
When we speak about Statistics, we usually think in numerical data, related to a specific period of time. We name statistics to data and series of Gross National Product (“GNP”), inflation, stock markets, unemployment, etc. But Statistics is much more than a set of figures. Statistics is a science, which provides us research methods to apply to the collected data in order to make an objective analysis of a specific phenomenon. This is a textbook which objective is to introduce the students in the basic knowledge of what is the Descriptive Statistics, and how to use the different data analysis techniques. We also include several solved exercises in order to achieve a more practical approach of the different lessons.
