Paper Summary

ANCOVA is a method used in research to control for factors that might affect the results of a study. It can help increase the accuracy of statistical tests and adjust for differences between groups. However, it is important to use covariates carefully, as they may not always work as intended. In some cases, using covariates in non-randomized studies can lead to unexpected outcomes.
