General methodology developed to discriminate among relatively large number of objects quickly. It gathers data and processes the collected information; the subjects are assigned the task of sorting a number of statements by placing a specific number of statements in each sorting category; the emphases are on determining the relative ranking of stimuli by individuals and in deriving cluster of individuals who display similar preference ordering of stimuli. For example, respondents are given hundred attitude statements on individual cards and are asked to place them into eleven
piles ranging from “most highly agreed with” to “least highly agreed with”.
