It is widely used in various disciplines, from physics, social sciences to humanities, and even in industrial and commercial and government information decision-making. With the acceleration of digital process, people are increasingly hoping to summarize some empirical laws from a large number of data, thus providing some basis for later decision-making. Statistics major is not just a literal expression, but statistics, which includes investigation, collection, analysis and prediction. It has a wide range of applications.
The specialty of extended data statistics is divided into three major directions: mathematical statistics, economic statistics and applied statistics. The gap between the direction of mathematical statistics and the direction of economic statistics is not very big. Mathematical statistics mainly studies the basic theories and methods of statistics. Economic statistics is a science that provides scientific investigation, collects economic information, describes and analyzes economic data, and predicts and supervises the social and economic operation process. Applied statistics is mainly to investigate and collect the data information of the observed object, analyze the characteristics of the observed object through descriptive statistics and other technologies, find out the law of things, predict and supervise, so as to realize the benign operation of social economy.
Through the study of statistics, we can master all kinds of data analysis techniques, understand the frontier theory of statistics, master the ideas of scientific investigation and study, and learn the use technology of statistical analysis software. Learning statistics requires a certain mathematical foundation and familiarity with computer operation. In practical work, statistical work needs to be completed with the help of various statistical analysis software.
