The column is strictly positive and centered at about 5.8, far from both 0 and 1, with a bounded range of 4.3 to 7.9. The name has no ratio tokens, so it is additive. It is a per-specimen physical attribute (cm), and summing it across different flowers is not meaningful, while averaging is the natural rollup. That points to intensive_additive rather than real_additive. Confidence is moderate because "length" is extensive in the physical sense and could be read as real_additive.</reasoning> <table_type_conflict>false</table_type_conflict> </result>
