Technique Overview
Introduction to Exploratory Analysis Definition
Exploratory data analysis (EDA) is the process of examining and summarising data to understand its structure, quality and main characteristics before drawing conclusions. It uses techniques such as summary statistics and visualisations to identify patterns, trends, relationships, unusual values and potential issues that may require further investigation (Tukey, 1977; Komorowski et al., 2016).
