Tip
If X and Y have the same count, the tool treats them as paired observations for regression. Otherwise, X and Y are analyzed separately (boxplot + density + summary).
Boxplots (Tukey) + outliers Hover/tap points or box/whiskers for a clean tooltip
Boxplot — X —
Boxplot — Y shown when Y has data
Quartiles: Tukey (median of halves). Outliers: values outside fences (Q1 − 1.5·IQR) or (Q3 + 1.5·IQR).
Density (KDE) — X —
Density (KDE) — Y shown when Y has data
Summary statistics n, min/max, mean, median, quartiles, IQR, SD, Tukey outliers
X —
Y shown when Y has data
