A Likert scale is a psychometric scale used to measure attitudes, opinions, or behaviors quantitatively. It is named after its inventor, American social psychologist Rensis Likert. A Likert scale question consists of a statement or a question, followed by a series of five or seven response items. Respondents are asked to indicate their level of agreement or disagreement with the statement or question on a scale that ranges from strongly agree to strongly disagree. The Likert scale assumes that the strength and intensity of the experience are linear, and attitudes can be measured. The scale can be used to measure a wide range of variables, such as sentiment, satisfaction, quality, importance, and likelihood. Likert scales are commonly used in survey research, as well as in fields like marketing, psychology, or other social sciences. The scale can be created as the simple sum or average of questionnaire responses over the set of individual items (questions) . However, it is important to note that a Likert scale refers only to the scale proper, which emerges from collective responses to a set of items, and not the format in which responses are scored along a range.
