Abstract

ABSTRACT This Article discusses reasons for the contemporary emphasis on evaluating the replicability of results from psychological research. Three logics for empirically evaluating the replicability of sample results—cross-validation, the jackknife, and the bootstrap—are described. A small heuristic data set is employed to make the discussion more concrete and accessible.
