A scaling procedure which insists upon unidimensionality is:
A) Thurstone scale
B) Likert scale
C) Guttman scale
D) Semantic Differential scale

Question

Quizplus · Accepted Answer

A Guttman scale is designed to measure a single latent variable or construct in a unidimensional way. In this method, items are arranged in increasing levels of intensity, and respondents must agree to items at lower levels in order to endorse items at higher levels. This creates a hierarchical structure of responses, which can be used to determine the strength of the underlying construct. Thurstone scales and Semantic Differential scales do not require unidimensionality, and Likert scales can be designed to measure multiple constructs.
