Responses to several Likert questions may be summed providing that all questions use the same Likert scale and that the scale is a defensible approximation to an interval scale, in which case the central limit theorem allows treatment of the data as interval data measuring a latent variable.
Scaled questions – Responses are graded on a continuum (e.g.: rate the appearance of the product on a scale from 1 to 10, with 10 being the most preferred appearance). Examples of types of scales include the Likert scale, semantic differential scale, and rank-order scale. (See scale for further information)

[7] [8] These responses can be scored using the Likert or GHQ scale. [8] Using the Likert scale the response choices are given the values 0, 1, 2, and 3 respectively. [7] [8] When a participant completes the questionnaire the values of their responses are then summed to give a final score between 0 and 180. Using the GHQ scale, the response ...
A rating scale is a set of categories designed to obtain information about a quantitative or a qualitative attribute. In the social sciences , particularly psychology , common examples are the Likert response scale and 0-10 rating scales, where a person selects the number that reflecting the perceived quality of a product .

Each scale asks twenty questions each and are rated on a 4-point scale. [10] Low scores indicate a mild form of anxiety and high scores indicate a severe form of anxiety. Both scales have anxiety absent and anxiety present questions. Anxiety absent questions represent the absence of anxiety in a statement like, “I feel secure.”
