Statistics uses the scientific method and mathematics to analyze and understand collective phenomena. It deals with the quantity and quality of a phenomenon under uncertain conditions. This discipline involves collecting and analyzing information to describe and estimate the characteristics of a population.

  1. Pimentel Rodriguez Darinet Capuano Anna Statistica /Statistics

  2. It makes use of the scientific method [ 1 ] and mathematics to study the ways in which a collective phenomenon can be summed up and understood . This happens through the collection and analysis of information about the phenomenon studied. Statistics is a discipline that has as its goal the study of quantity and quality of a particular phenomenon in conditions of uncertainty or nondeterminism , ie not complete knowledge of it or part of it . The term statistics, in everyday language, also simply indicates the numerical results ( statistics mentioned in the news , such as : inflation , GDP etc . ) of a process of synthesis of the observed data .

  3. Statistics Statistics is somehow linked to the theory of probability returning both in the wider context of the theory of random phenomena , but while the probability theory deals with providing probabilistic theoretical models or probability distributions adaptable to various real random phenomena defining the parameters of random variable in question , the statistical part of a random sample to describe its statistical properties , or ascend or infer the underlying probabilistic model and the estimation of its parameters ( mean, variance , standard deviation , mode, median ) . The statistical science is commonly divided into two main branches : • Descriptive statistics • inferential statistics

  4. descriptivestatistics set of methods that concern the collection , presentation , the definition of a set of data related to a population in order to describe the characteristics adequately. The data collected can be classified through simple or complex deployments : a distribution is called " simple" if every individual in the population or sample is associated with a single character a distribution is called a " complex " if every individual in the population or sample are associated with at least two characters inferentialstatistics of method together that allow , relying only on the ratings made ​​on the sample , to estimate the parameters of one or more characters of a population . From a philosophical point of view , these are mathematical techniques to quantify the process of learning through experience mathematicalstatistics is the branch of mathematics that deals with collecting, grouping , analyzing and interpreting the data for certain phenomena , and some predictions regarding the development of these phenomena in the future
