Question

Quizplus · Accepted Answer

A Likert scale yields interval data if and only if the distances between each scale point are equal. This means that the values on the scale represent equal intervals of the underlying construct being measured, such as attitude or satisfaction. The other options, B, C, and D, are not necessarily true for all Likert scales. Likert scales can have an even or odd number of scale points, may or may not have verbal labels, and are commonly used in marketing surveys.
