01
Scatterplots and associationScatterplots and association is a communication and diagnostic technique that maps data or results into a visual form. A useful visual makes comparisons easy, exposes uncertainty and supports the analytical question rather than merely decorating the report.
02
Cross-tabulation and contingency tablesCross-tabulation and contingency tables is a communication and diagnostic technique that maps data or results into a visual form. A useful visual makes comparisons easy, exposes uncertainty and supports the analytical question rather than merely decorating the report.
03
Grouped summariesGrouped summaries is a practical concept within Bivariate & Multivariate Exploration. It helps turn the broader workflow stage “3 · Data Understanding & EDA” into an explicit analytical decision that can be explained, implemented and checked. The concept should be understood in terms of purpose, mechanism, assumptions, evidence and downstream consequences.
