A Likert scale is a popular survey tool used to measure attitudes, opinions, or perceptions. It typically consists of a statement followed by a range of response options, usually from "strongly disagree" to "strongly agree." Respondents select the option that best reflects their feelings, allowing researchers to quantify subjective data. Likert scales can vary in the number of response options, commonly ranging from 5 to 7 points. This format helps capture the intensity of feelings, making it easier to analyze trends and patterns in responses. They are widely used in fields like psychology, social sciences, and market research.
