Which of the following is an example of exploratory analysis?
Exploratory data analysis (EDA) involves examining data—often through visualizations—without a predefined hypothesis, in order to discover patterns, trends, and relationships. This is in contrast to confirmatory analysis, which starts with a preconceived assumption and tests whether the data confirms or disproves it. Noticing patterns in visualization charts is a core activity of exploratory analysis, whereas confirming or disproving a preconceived assumption describes confirmatory (hypothesis-driven) analysis.
