Which scale is commonly used for measuring attitudes or opinions with multiple response options?

The Likert Scale is specifically designed to measure attitudes or opinions by providing respondents with multiple response options, typically showcasing a range of agreement or disagreement. This scale commonly uses a spectrum, such as "strongly agree," "agree," "neutral," "disagree," and "strongly disagree," allowing individuals to express varying degrees of their feelings towards a specific statement. By capturing this information, researchers can quantify subjective perceptions and analyze trends in attitudes effectively.

This method of measurement is particularly advantageous in survey research, as it not only evaluates the strength of attitudes but also enables comparisons across different groups or conditions. The structured response options facilitate the aggregation of data for statistical analysis, making it a valuable tool for understanding public opinion.

Some other scales exist for measuring attitudes or characteristics, but they do not provide the same level of granularity in responses as the Likert Scale does. For instance, nominal scales classify data into distinct categories without any order, ordinal scales rank items but do not quantify the differences between them, and interval scales offer numerical distances but often lack a true zero point relevant for attitudes. Hence, the Likert Scale is distinctly suited for capturing nuanced opinions and attitudes in research contexts.
