Description: In psychology and language research, attempts to replicate published findings are less successful than expected. For properly powered studies replication rate should be around 80%. The Open Science Collaboration (2015) could only replicate 36% of studies that were selected from different areas of psychology. This can partly be explained by publication bias and fraud, but most likely reflects a lack of power in the original studies. . We checked how we could estimate the power of three priming studies using simulation and tracked which variables influenced power. This directory contains the datasets used and a template for a power simulation.
