Introduction: Data analysis refers to the process of using appropriate statistical analysis methods to analyze a large number of collected data, extract useful information and form a conclusion, and conduct detailed research and summary on the data.
In the field of statistics, data analysis is divided into descriptive statistical analysis, exploratory data analysis and confirmatory data analysis. Exploratory data analysis focuses on finding new features in data, while confirmatory data analysis focuses on confirming or falsifying existing hypotheses.
Exploratory data analysis is a method to analyze data in order to form hypotheses worth testing, which is a supplement to traditional statistical hypothesis testing methods.
