I would recommend that you read the A Practitioner's Guide to Cluster … Clustered standard errors are often useful when treatment is assigned at the level of a cluster instead of at the individual level. For example, suppose that an educational researcher wants to discover whether a new teaching technique improves student test scores. She therefore assigns teachers in "treated" classrooms to try this new technique, while leaving "control" classrooms unaffected. When analyzing her results, she may want to keep the data at the student level (for …
