Document Summary
Demonstrates scores that represent high scores so they can be separated from average (prevalent) scores, as well as the lower scores. Asmd, the shape of the distribution stays the same. Represents a negative or positive correlation amongst our variables score by 10. Standardized and allows us to compare our scores to a normative set. % of people (cid:449)ho s(cid:272)o(cid:396)ed (cid:271)elo(cid:449) the (cid:862)pe(cid:396)so(cid:374) (cid:449)e a(cid:396)e i(cid:374)te(cid:396)ested i(cid:374)(cid:863) All the people who scored below + half of the people who scored the exact same.
