The column name "Happiness Score" indicates an intensity/level measurement, not a ratio or extensive quantity. Center-of-mass at 5.38 (far from both 0.0 and 1.0), bounded range [2.905, 7.526], and strictly positive values all confirm this is an absolute level measure. Summing happiness scores across entities is meaningless; averaging is the natural aggregation. This is a classic intensive_additive measure - a scored level/intensity at entity grain. </reasoning> <table_type_conflict>false</table_type_conflict> </result> ```
