answer:Exploratory Data Analysis (EDA) is an approach to analyzing data sets to summarize their main characteristics, often with visual methods. It is a crucial step in the data analysis process, where the analyst makes use of various techniques to understand the underlying structure of the data, identify outliers, examine relationships between variables, and extract important variables for the modeling process. EDA is primarily done using basic statistical techniques and data visualization tools and helps to uncover hidden trends, patterns, and insights in the data. The primary goal of EDA is to help analysts to make informed decisions by providing a better understanding of the data.
