Demonstration of Single-Case Two-Sample Randomization-Test Procedures: Underperforming Children’s Implementation of an Effective Memory Strategy

Abstract

Recently developed randomized-test procedures for two independent-samples single-case designs are presented and applied to a memory-strategy intervention study with eight underperforming students from low SES backgrounds. Research design aspects, data-analysis features, and various output measures are provided to demonstrate the potential utility of the randomization procedures for researchers who seek to examine comparative intervention effects with scarce resources but in a methodologically rigorous manner.
