The column name "Happiness.Score" indicates an absolute level/rating, not a ratio. Center-of-mass is 5.35 (far from both 0 and 1), range [2.69, 7.54] suggests a bounded scale typical of survey scores. This is an intensive measure - a level that should be averaged when aggregating across entities, not summed. No evidence of ratio behavior (not centered on 1.0, negative log_symmetry_gain). </reasoning> <table_type_conflict>false</table_type_conflict> </result> ```
