Column name "column_count" indicates a structural property (count of columns per entity), not an extensive quantity that accumulates. The values (min=2, max=55, mean=8.6, median=6) represent absolute levels - each entity has a specific number of columns. Summing these counts across entities is meaningless (you cannot add "10 columns" + "11 columns" to get "21 columns of what?"), but averaging them to find typical column count is sensible. This is a classic intensive property: an absolute level where mean is the natural rollup, not sum. </reasoning> <table_type_conflict>false</table_type_conflict> </result> ```
