Abstract
Nonparametric methods are appropriate when certain assumptions about distributions that common parametric methods make are questionable. In this entry, we review nonparametric statistical tests based on exact or simulated sampling distributions. We also discuss methods for nonparametric data exploration and nonparametric regression and we explain computer-based methods for estimating standard errors and confidence intervals and regression functions. The methods are illustrated using Pisa data from 2019.
