Univariate Exploration
Univariate Exploration groups the core ideas a learner needs at the 3 · data understanding & eda stage. Work through the lessons in order when new to the area, or use them independently as a reference when implementing an analysis.
Learn the mechanism one decision at a time
Work through the lessons in order if the topic is new. If you already know the basics, open the specific leaf lesson that matches the operation, diagnostic or failure mode you need.

Frequency tablesFrequency 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.
02Measures of centreMeasures of centre is a practical concept within Univariate 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.
03Measures of spreadMeasures of spread is a practical concept within Univariate 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.
04Quantiles and percentilesQuantiles and percentiles is a practical concept within Univariate 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.
05Histograms and density plotsHistograms and density plots 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.
06Boxplots and robust summariesBoxplots and robust summaries 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.
