A Likert scale (/ ˈlɪkərt / LIK-ərt, [1][note 1]) is a psychometric scale named after its inventor, American social psychologist Rensis Likert, [2] which is commonly used in research questionnaires. It is the most widely used approach to scaling responses in survey research, such that the term (or more fully the Likert-type scale) is often ...
Thurstone scale. In psychology and sociology, the Thurstone scale was the first formal technique to measure an attitude. It was developed by Louis Leon Thurstone in 1928, originally as a means of measuring attitudes towards religion. Today it is used to measure attitudes towards a wide variety of issues.
Elaboration likelihood model. The elaboration likelihood model (ELM) of persuasion [1] is a dual process theory describing the change of attitudes. The ELM was developed by Richard E. Petty and John Cacioppo in 1980. [2] The model aims to explain different ways of processing stimuli, why they are used, and their outcomes on attitude change.
In social psychology, Social judgment theory (SJT) is a self-persuasion theory proposing that an individual's perception and evaluation of an idea is by comparing it with current attitudes. According to this theory, an individual weighs every new idea, comparing it with the individual's present point of view to determine where it should be ...
Definition: Guttman scale is a data set for which there exists an ordinal variable, X, with a finite number m of categories, say, 1,..., m with m ≥ max j (kj) and a permutation of subjects' profiles such that each variable in the data set is a simple function of X. Despite its seeming elegance and appeal for exploratory research, this ...
Hendrick and Hendrick (1986) developed a self-report questionnaire measure of Lee's love styles, known as the Love Attitudes Scale (LAS). [10] A shortened version of the LAS, presumably for researchers trying to keep their surveys as concise as possible, was later published, [17] and other variations appear to have been used by some researchers ...

The scale has become a method to measure people's thoughts and feelings from opinion surveys to ...
Aircraft flight dynamics. Flight dynamics is the science of air vehicle orientation and control in three dimensions. The three critical flight dynamics parameters are the angles of rotation in three dimensions about the vehicle's center of gravity (cg), known as pitch, roll and yaw. These are collectively known as aircraft attitude, often ...
