Likert Scale

People commonly call any five-point agreement question a “Likert scale.” Strictly, an individual agreement statement is a Likert-type item, while a Likert scale combines responses from multiple related items to measure an underlying attitude. The distinction matters when deciding how to summarize scores or compare groups.

Good survey design uses clear, single-idea statements and response labels that make the direction of agreement obvious. “Strongly disagree” through “strongly agree” is a common format, but response options should match the construct being measured. Avoid questions that combine several topics, lead respondents toward praise or assume they used a feature they never encountered.

Because ordered responses are not automatically equal-interval measurements, analysis choices should be justified. Report question wording, the response categories and missing-data handling. An apparent increase in the average score may reflect changed respondents, sampling or question wording rather than a genuine product improvement.
