Exploratory Data Analysis, or EDA, is an approach and typically the first step to data analysis. EDA focuses on exploring data to:
- understand a data set’s underlying structure and variables;
- develop intuition about the data set;
- consider how that data set came into existence;
- and decide how it can be investigated with more formal statistical methods.
Basically, EDA gives you the tools to quickly look at data and figure out whether there are big trends or patterns that are worth exploring before you pull out your bigger data analysis toolbox to spend time on in-depth analysis.
