CORE DEFINITION

A technique that reduces the associations between categorical variables to a two-dimensional space, visualizing the correspondence between rows and columns.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Making categorical variables visible. Numerical variables are easy to plot, while relationships among categorical variables are presented by this method.

anchor

Anchor fast decisions

Based on the chi-square distance of the contingency table, it simultaneously reduces the row and column variables to the same low-dimensional space, so that categories with strong associations are close to each other in the plot, thereby visualizing the relationships among categorical variables.

Berkson's Paradox

Berkson's paradox, also known as Berkson's bias, collider bias, or Berkson's fallacy, refers to the situation where people's intuitive observations do not match the actual conditional probabilities and rigorous statistical results; that is, the seemingly correlated factors that people discover are actually unrelated. This occurs when biased samples are included in the study design and bias exists. The paradox was proposed by American physician and statistician Joseph Berkson in 1946.
