What is Exploratory Data Analysis?

Exploratory Data Analysis (EDA) is the process of preliminary data analysis aimed at understanding its structure, identifying patterns, anomalies, and hypotheses for further analysis or modeling.

For a product manager, EDA helps to:

• Quickly assess the quality and completeness of data.
• Understand the main characteristics of users or processes.
• Identify unexpected dependencies and trends.
• Prepare data for decision-making or setting tasks for analysts and developers.

Example: when analyzing user behavior data on a website, histograms of visits over time can be constructed, segments with high conversion can be identified, or where users most often leave the sales funnel can be determined.
