Exploratory Data Analysis

Exploratory data analysis (EDA) is an investigative process in which you use summary statistics and graphical tools to get to know your data and understand what you can learn from it.

With EDA, you can uncover patterns in your data, understand potential relationships between variables, and find anomalies, such as outliers or unusual observations. The goal is to generate interesting questions or hypotheses that you can test using more formal statistical methods.
