Data for an experiment demonstrating the usefulness of covariates in increasing the power of experimental studies, as reported in a tutorial in the Journal of Consumer Research.
The study manipulates mood (happy/sad) through autobiographic recall and measures its effect on the enjoyment of a piece of classical music, while controlling for self-reported enjoyment of another piece of classical music (measured prior to the mood manipulation).
