For most variable types (interval, ratio, nominal), you can find the average. This does not apply to Likert scale data. The average value in a Likert scale cannot be found because you don`t know the “distance” between the data elements. In other words, while you can find an average of 1.2 and 3, you can`t find an average of “consent,” “no” and “neutral.” In the area of investigation, this is a question of consent/refusal (it is named after the response options it uses). This type of question uses a non-scale, consent scale. Essentially, a simple and inconsistent scale is a series of response options ranging from strong support to strong rejection. It allows respondents to respond more precisely and suggests that you analyze more nuanced answers. This kind of question has been very popular with investigators for decades. What for? Most Likert scales are classified as ordinal variables. If you are 100% sure that the difference between the variables is constant, they can be treated as interval variables for testing purposes.
In most cases, your data is ordinal, because it is impossible to tell the difference between, say, “highly consenting” and “consenting” versus “accept” and “neutral.” We were all asked in a survey how much we agreed or disagreed with something. It`s a Likert scale. 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. The Likert scale is important for research because it can be used to measure a person`s attitude by measuring how much they agree or disagree with a particular question or statement. Likert Scale issues are one of the most used tools in the search for public opinion. This scale offers 7 different response options related to an agreement that would be clear enough for interviewees without being confused. These scales can be used in the same way to measure probability, importance, frequency and many other factors. An effective Likert scale includes a number of questions you ask people to answer, and ideally 5-7 balanced answers from which people can choose. It often comes with a neutral center and essentially measures the level of agreement, so these are not always numbered scales. When respondents respond to a Likert item, they indicate their agreement or disagreement in a symmetrical agree scale for a number of statements.
Thus, the area captures the intensity of their feelings for a particular element.  As such, Likert-Skalen has found an application in psychology and social sciences, statistics, economics and marketing.  In addition to measuring match data, Likert scales can also measure other variations such as frequency, quality, meaning and probability, etc. Overall, a Likert article is merely a statement that the respondent must assess by giving it a quantitative value for each type of objective dimension, a degree of agreement and/or disagreement being the most commonly used dimension. So if you say they don`t agree… what does this mean as opposed to loud voices? and the difference or the degree of difference… how do I consider the responses A Likert scale assumes that the strength/intensity of a posture is linear, i.e. on a continuum to strongly agree to strongly oppose, and gives the assumption that the settings can be measured. To directly model Likert binary responses, they can be represented in a binomial form by synthesizing separately consistent and incompreostable responses.
