The column name "confidence" indicates a probability or certainty score - an intensive level bounded in [0,1]. Values range [0.25, 1.0] with median 0.95, centered away from both 0.0 and 1.0. This is not a ratio (no implicit division, not centered on 1.0) but an absolute intensity measure. Summing confidence scores across entities is meaningless; averaging them is the natural aggregation. Classified as intensive_additive with mean as primary reducer. </reasoning> <table_type_conflict>false</table_type_conflict> </result> ```
