Explanation

Exploratory Data Analysis (EDA) is the initial step in data analysis where the analyst investigates the dataset to discover patterns, spot anomalies, test hypotheses, and check assumptions.

Trend analysis examines data over time to identify directional movement - not a general-purpose preliminary investigation.
