Column name "sepal_length" indicates a physical measurement (length). Center-of-mass at 5.84 with range [4.3, 7.9] is far from both 0.0 and 1.0, ruling out ratio_multiplicative. This is an absolute physical level/intensity measured per entity (iris flower). Summing sepal lengths across flowers is meaningless; averaging is the natural aggregation. Classified as intensive_additive with high confidence. </reasoning> <table_type_conflict>false</table_type_conflict> </result> ```
