What scale is commonly used to measure people's attitudes or opinions, often using a 5-point format?

The Likert Scale is widely recognized for measuring attitudes or opinions by presenting respondents with a range of answer options that typically include levels of agreement or disagreement. The classic format features five points, ranging from "strongly agree" to "strongly disagree," allowing for a nuanced expression of feelings about a particular statement. This gradation enables researchers to capture degrees of opinion rather than a simple binary choice, providing richer data for analysis.

Designed to assess the intensity of feelings, the Likert Scale is effective in social sciences for evaluating variables such as satisfaction, quality of life, or agreement with a particular statement. Its straightforward nature makes it user-friendly for participants, leading to higher response rates and more reliable data. This versatility is why it has become a standard in surveys and questionnaires across various fields.
