The column name "Training time (hours)" indicates a duration measurement—an absolute physical quantity with unit "hours". The values (0.1 to 9022.8 hours) represent training duration per entity, which is an intensive property: summing training times across different entities is meaningless (you cannot add "3 hours for entity A" + "5 hours for entity B" to get "8 hours of training"), but averaging them is sensible. This is a classic intensive_additive measure—a level or intensity that should be averaged, not summed, when aggregating across entities. </reasoning> <table_type_conflict>false</table_type_conflict> </result> ```
