Derived statistics or secondary statistics in the strict sense are attributes of a character in the SPECIAL system which are based on (or derived from) the character's primary statistics. More commonly, the term refers to all character attributes which only exist as a function of another value, i.e. character attributes which the player cannot determine or influence directly.
