What is Likert Scale?
A Likert scale is a common survey format that asks respondents to rate their level of agreement, satisfaction or frequency on a ordered set of response options (for example: Strongly disagree → Strongly agree). It’s used to capture attitudes and opinions with simple, comparable responses.
A Likert scale usually presents a statement (a Likert item) and a series of ordered response options that reflect increasing intensity (commonly 5 or 7 points). Respondents choose the option that best matches their view — for example: Strongly disagree, Disagree, Neutral, Agree, Strongly agree. Researchers often combine several related Likert items into a composite score (often called a Likert scale or index) to measure a broader attitude or construct. Technically the responses are ordinal (they have a clear order but not equal numeric intervals), though many practitioners treat aggregated scores as approximately interval for analysis.
Usage example
Question: “I feel well informed about school events.” Response options: 1 Strongly disagree, 2 Disagree, 3 Neither agree nor disagree, 4 Agree, 5 Strongly agree.
Practical application
Likert formats are useful because they are quick for participants to answer and simple to compare across groups. For Hearo users this matters because consistent, clear response labels increase response quality across languages — you can translate the same labelled options once and apply them across every survey version, then review translated responses centrally. When designing surveys, choose the number of points and labels with your audience in mind, ensure labels translate clearly, and consider combining several items to measure a single concept reliably.
FAQ
Is a Likert scale ordinal or interval data?
Individual Likert items are ordinal — the options are ordered but don’t guarantee equal intervals between them. When you combine multiple related items into a composite score, the result is often treated as approximately interval for analysis, but you should choose statistical tests that match your data and sample size.
How many points should I use — 3, 5 or 7?
Five-point scales are most common because they balance nuance and simplicity; seven points give finer distinction but can confuse some respondents. Three points are very coarse and often lose subtlety. Consider your audience’s literacy, survey length and whether labels will translate clearly across languages.
Should I include a neutral or ‘no opinion’ option?
A neutral option can be useful when genuine neutrality or lack of knowledge is possible, but it can also encourage satisficing (picking the middle to avoid thinking). If you expect many undecided respondents, include it; otherwise consider forcing a direction or adding ‘Don’t know’ as a separate option.
Any special considerations for multilingual surveys?
Yes — translate response labels carefully so intensity and tone match across languages. Some cultures use midpoints differently, so monitor patterns by language. Use consistent, simple labels and test translations with native speakers. Hearo’s workflow (automatic translation plus participant feedback and review) helps maintain consistent, reviewable labels across all language versions.
