Exploratory Data Analysis (EDA)

An open-ended investigation of a dataset with summary statistics and visualizations to understand structure, spot anomalies and form hypotheses.

Definition

EDA, popularized by John Tukey, precedes formal modeling. It uses histograms, box plots, scatter plots, correlation matrices and missing-value analysis.

Exam tip

EDA comes before modeling; it generates hypotheses rather than confirming them.
