This chapter presents an overview of exact and Monte Carlo permutation statistical methods. Six sections describe and illustrate the basics of permutation statistical methods. The first section simply provides an introduction to permutation statistical methods. The second section describes and illustrates permutation test statistic \(\delta \) . The third section describes exact and Monte Carlo probability values for test statistic \(\delta \) . The fourth section describes the exact expected value of test statistic \(\delta \) . The fifth section describes a chance-corrected measures of effect size for test statistic \(\delta \) . The sixth section illustrates a Monte Carlo permutation analysis.
