A teacher wants to know his students’ favorite holiday in all of his math classes.

Reason: the teacher’s population (all his students) is small and easy to contact, so surveying the entire population is reasonable. The other situations involve large or hard-to-census populations (all customers, all university students, or all trees in a national forest).
