Column name "Life.Expectancy" signals an intensive physical level (years of life). Values are bounded [0.0, 0.95], centered at mean=0.55/median=0.61, far from both 0.0 and 1.0, consistent with a normalized or scaled intensity measure. Contains a zero (1 row), which weakly opposes multiplicative. Life expectancy is a classic intensive quantity where averaging across entities is meaningful but summing is not. High confidence in intensive_additive. </reasoning> <table_type_conflict>false</table_type_conflict> </result> ```
