Teaching and learning about tree-based methods for exploratory data analysis




Quantitative information about important societal topics are increasingly accessible to the general public and to individual citizen. Making sense of these data requires the ability to explore, understand, and reason about complex multivariate data. For such data, we need flexible and robust analytical methods that can deal with nonlinear relationships, mixed type variables, high-order interactions and missing values. Classification and regression trees are a method that is well suited for the analysis of such complex data. Besides reflecting on tree-based methods for teaching understanding about complex social data the purpose of this paper is to introduce the digital tool EasyTREE which is designed to help understanding about construction and interpretation of decision trees and supports critically evaluating the strength and pitfalls of the tree method.
