![]() The first step of statistical work is the collection of data, which, if well organized, saves effort in subsequent operations and allows the correct setting for the analysis. The term “Statistics” was introduced in the seventeenth century with the meaning of “science of the state” ( 1), which aims to gather and sort information to the public administration regarding: size and composition of the population, migration, demographic changes, birth and mortality tables, data on businesses, crops, the distribution of wealth, education and health. In this sense, statistical analysis plays a central role. The value of a scientific study is recognized by the community only if it is supported by numerical evidence that warrants the validity.
