Set of procedures used to measure or manipulated variables (:. Ensures abstract concepts are discussed with concrete terms. Help researchers communicate their ideas to others (understanding of definitions: e. g. Researcher changing the conditions to which participants are exposed to: how variable is manipulated depends on: and terms)
