Definition


The Likert scale graduates the assessment of a series of items. It has four to seven degrees, from "strongly disagree" to "strongly agree". Its goal is to register the approval or disapproval of a particular portion of the public by assessing its attitude. It is called a forced choice scale when it has an even number of degrees, while an odd number scale has a central degree that leaves the possibility to not express an opinion. The Likert scale is used in marketing as well as in social psychology.
