Exploratory Data Analysis

Exploratory Data Analysis (EDA) is an iterative approach to analysing datasets to summarise their main characteristics, often employing visual methods and statistical summaries. The primary objective is to investigate the underlying structure, detect anomalies, and check assumptions before formal modelling. Formally, EDA involves the calculation of descriptive statistics (e.g., mean, variance) and the construction of visualisations to characterise the distribution of the data.
