Likert scales (although ordinal scales) are often treated as interval scales during statistical analyses. There have been attempts to add a modifier (such as moderately, somewhat, or slightly) to the intermediate anchors of Likert scales (i.e., disagree and agree) to help them...
The interval scale is defined as the 3rd quantitative level of measurement where the difference between 2 variables is meaningful. Let's explore!
TheLikert Scalegives another example of how you can’t be sure about intervals with ordinal data. What is the interval between “strongly agrees” and “agrees”? It’s practically impossible to put any kind of number to that interval. Even if you could put a number to the interval, the ...
Analysts often represent ordinal scales using numbers, such as a 1-5 Likert scale that measures satisfaction. In number form, you can calculate average scores as with quantitative variables. However, the numbers have limited usefulness because the differences between ranks might not be constant. Cons...
This scale was introduced by Likert (1932) and is widely employed in sentiment analysis, satisfaction surveys, opinion mining, and, more recently, information retrieval processes within the context of recommender systems (Pang and Lee, 2008). Responses on an ordinal scale can be scored or ranked...
The Likert Scale: agree, strongly agree, disagree etc. TheLikert Scalegives another example of how you can’t be sure about intervals with ordinal data. What is the interval between “strongly agrees” and “agrees”? It’s practically impossible to put any kind of number to that interval....
There is no true zero on an interval scale, which is what distinguishes it from aratio scale. On an interval scale, zero is an arbitrary point, not a complete absence of thevariable. Common examples of interval scales include standardized tests, such as the SAT, and psychological inventories...

Figure 4.7.A set of questionnaire items organized in a Likert Scale. The responses are examples of interval scale data. There is some disagreement among researchers on the assumption of equal gradations between the items inFigure 4.7. Do respondents perceive the difference between, say, 1 and 2...
As an extended form of intuitionistic fuzzy set, the theory of interval-valued intuitionistic fuzzy set (IVIFS) can describe fuzziness more flexibly. This
