This measurement satisfaction scale offers 5 response options, as satisfied and dissatisfied with a neutral option in the middle. These options are linked to other options that would offer respondents the desired variations. In addition to measuring match data, Likert scales can also measure other variations such as frequency, quality, meaning and probability, etc. To measure frequency, customer surveys may even use a Question from Likert Skala. The 2-point Likert scale is the simplest example of the Likert scale, where there are only two Likert options, such as. B, and do not fit as two poles of scale. It is usually used to measure agreement. A scale can be established as a simple or average sum of questionnaire responses on the set of individual elements (questions). The Likert scale assumes that the distances between the different selection options (response option) are the same. Many researchers use a number of such elements that are highly correlated (which have a great internal consistency), but also that the entire field studied is covered (which requires less than perfect correlations).
Others stick to a standard in which „all elements are considered to be replications of each other, that is, as parallel instruments.” 197 On the other hand, modern test theory deals with the difficulty of each element (of ICCs) as information intended to feed elements of scale. A good Scale of Likert, as above, will represent a symmetry of categories via a center with clearly defined language qualifiers. In the case of such a symmetrical scale, equidistant attributes are generally observed more clearly or, at the very least, deduced. If a Likert scale is symmetrical and equidistant, it behaves more like a measure of the interval. While a Likert scale is actually ordinal, if it is well represented, it can still bring a level measurement closer to interval. This can be beneficial, because if it has only been treated as an ordinal scale, some valuable information could be lost if the „distance” between Likert`s articles was not available for review. The important idea is that the type of analysis that is appropriate depends on how the Likert scale was presented. When the user responds to an element of the Likert scale, he responds explicitly on the basis of his level of consent or disagreement. These criteria are used to determine the degree of agreement or disagreement of respondents.
The Likert scale assumes that the strength and intensity of the experience are linear. It is therefore a complete agreement to a total disagreement, provided that attitudes can be measured. Once the questionnaire is completed, each item can be analyzed separately or, in some cases, article responses can be added together to create a score for a group of articles. Therefore, Likert scales are often called summing scales. Rensis Likert, the developer of the scale, said his name.   Some have claimed that Likert`s name is „one of the most mispronounced in the field” because many people pronounce the name of the scale as /la.k`rt/LY-k`rt.  In its final form, the Likert scale is a five- or seven-point scale that allows the individual to express how much he or she agrees with a given statement.
