Research by Labovitz [22] and Traylor [23] provide evidence that, even with rather large distortions of perceived distances between scale points, Likert-type items perform closely to scales that are perceived as equal intervals. So these items and other equal-appearing scales in questionnaires are robust to violations of the equal distance ...
Likert scale – Respondents are asked to indicate the amount of agreement or disagreement (from strongly agree to strongly disagree) on a five- to nine-point response scale (not to be confused with a Likert scale). The same format is used for multiple questions. It is the combination of these questions that forms the Likert scale.
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 .
One very frequently-used rating scale is a Likert scale. Usually, for clarity and efficiency, a single set of anchors is presented for multiple rating scales in a questionnaire. Collectively, a statement or question with an accompanying rating scale is referred to as an item.
Rensis Likert (/ ˈ l ɪ k ər t / LIK-ərt; August 5, 1903 – September 3, 1981) was an American organizational and social psychologist known for developing the Likert scale, a psychometrically sound scale based on responses to multiple questions. The scale has become a method to measure people's thoughts and feelings from opinion surveys to ...
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)
Differential Emotions Scale (DES) is developed on the basis of Differential Emotions Theory, which contends that emotions are closely related to the formation of personality. [15] The scale advances to DES-IV with the theoretical development. DES-IV includes 36 items using a 5-point frequency Likert scale (from rarely or never to very often).
The item-total correlation approach is a way of identifying a group of questions whose responses can be combined into a single measure or scale. This is a simple approach that works by ensuring that, when considered across a whole population, responses to the questions in the group tend to vary together and, in particular, that responses to no individual question are poorly related to an ...
