The correct formula is: 1.5 x (N-1) +1 where N is the score on a 7 point scale.
The correct formula is: 1.5 x (N-1) +1 where N is the score on a 7 point scale.
Can a 3-point scale also be called a Likert scale?? PS
The Likert type question is used to determine the respondent attitude or feeling on a particular specific item. There are numerous ways to set up the answer types on the Likert scale; see the related links.

real definition of likert scale?
See the related link for more information. The Likert scale with 5 points typically has a middle neutral (neither agree or disagree) choice. In the 4-point scale, the neutral choice is removed, so that person who is uncertain is forced to lean (even if slightly) one way or the other.
To create a Likert scale questionnaire, first define the statements or questions to be rated. Then, choose a scale, such as a 5-point scale ranging from "Strongly Disagree" to "Strongly Agree." Next, present the statements along with the scale and ask respondents to select the option that best represents their opinion. Finally, analyze the responses by calculating averages or percentages for each statement.
It depends on the specific likert scale, but generally it is the ordinal level

A Likert scale is considered a quantitative measurement tool because it assigns numerical values to responses and allows for numerical analysis of data.

The Likert Scale
If you are considering a single ordinal variable, determining the mode or median would be meaningful, but the mean or SD would not. Many researchers do consider likert-scale data to possess only ordinal qualities. However, leading research studies, for example in the marketing area, obtain measures such as means and standard deviations from likert-scale data. Indeed leading textbooks also follow this approach. One concern has been that the 'distances' between points on a likert scale are not equal, for example the 'distance' or 'difference' between a strongly disagree and disagree is not the same as the difference between disagree and neutral. A recent study discusses these issues, as well as demonstrating that data obtained from 5-point, 7-point and 10-point likert scales are approximately comparable in terms of mean score (once re-scaled) and various measures of variation and data shape. The study reference is Dawes, John "Do Data Characteristics Change According to the Number of Scale Points Used ? An Experiment using 5-point, 7-point and 10-point Scales" International Journal of Market Research, Vol 50 2008.
