Replication is already mainstream: Lessons from small-N designs

  • Daniel R. Little (a1) and Philip L. Smith (a1)


Replication is already mainstream in areas of psychology that use small-N designs. Replication failures often result from weak theory, weak measurement, and weak control over error variance. These are hallmarks of phenomenon-based research with sparse data. Small-N designs, which focus on understanding processes, treat the individual rather than the experiment as the unit of replication and largely circumvent these problems.
