Data Exploration

The process of investigating and examining datasets to discover patterns, spot anomalies, test hypotheses, and check assumptions, typically as a preliminary step before formal analysis. For blind and low-vision users, data exploration is particularly challenging because sighted analysts rely heavily on visual scanning and data visualizations to quickly identify trends and outliers. Screen reader users must instead traverse data sequentially, cell by cell, building mental models of data structure and content through auditory feedback, which places significant demands on working memory.
