What is a Likert scale? Definition, examples, and tips

Likert scales are a structured way for researchers to gather diverse opinions and attitudes. They allow respondents to express agreement, disagreement, or neutrality concerning statements or questions.

Named after Rensis Likert, these scales are widely used in disciplines such as psychology, sociology, and market research to quantify qualitative data effectively.

Let’s explore what makes up a Likert question, including examples, when you should use Likert scales, and how you can use them in your surveys.

To understand the Likert rating scale, you first need to understand what a survey scale is.

A survey scale represents a set of answer options—either numeric or verbal—that cover a range of opinions on a topic. It’s always part of a closed-ended question (a question that presents respondents with pre-populated answer choices).

A Likert scale is a rating scale used to measure survey participants' opinions, attitudes, motivations, and more. It uses a range of answer options ranging from one extreme attitude to another, sometimes including a moderate or neutral option. However, 4- to 7-point scales are the most popular.

So, what is a Likert scale survey question? Instead of asking a yes/no question like, "Do you like our product?", respondents rate their attitudes on a scale ranging from "don’t like at all" to "like it a lot." 

Using Likert scales, researchers and practitioners can effectively quantify and capture the complexity of individual opinions, psychology, and attitudes. For instance, someone who "likes the product but is not crazy about it" would probably give a Likert rating of "somewhat like it."

Likert scales (named after their creator, American social scientist Rensis Likert) are quite popular because they are one of the most reliable ways to measure opinions, perceptions, and behaviors.

Likert scales are easy to design and can be used for various topics and quantitative surveys.

Compared to binary questions, which give you only two answer options, Likert-type questions will get you more granular feedback about whether your product was just “good enough” or (hopefully) “excellent.” 

This method will let you uncover degrees of opinion that could make a real difference in understanding the feedback you’re getting. It can also pinpoint areas where you might want to improve your customer or employee experience.

Using the same Likert scales in longitudinal or recurring surveys can also track seasonal changes in customer attitudes. For example, you can send a quarterly survey to assess customer loyalty to your brand. With those data, you can see the quarterly and yearly changes in customer loyalty. This will help you understand your current and past brand health and, most importantly, predict how it may trend.

Likert scale surveys can come in many forms. Here are a few of the most commonly used question types.

Likelihood: How likely a respondent is to take a particular action, like signing up for a membership or purchasing a product. These questions are good if you’re trying to determine how likely someone is to do something instead of just how much they like the idea of something. 

Satisfaction: How satisfied are your customers with something your company offers or does? Asking satisfaction questions is a great way to figure that out. 

Importance: To gauge how strongly people feel about a certain service, product, or experience, you can ask a Likert scale question that measures how important something is to a customer. 

Likert scales are very flexible interval scales and you can adjust the scale points easily to fit your survey design. Some of the common are 4-point, 5-point, 7-point, and 10-point scales.

The 4-point Likert scale usually does not provide the middle or neutral points of the scale. This is typically used to make sure that respondents provide an attitude. An example of a 4-point Likert scale could look like this:

How satisfied or dissatisfied are you with the speed of product delivery?

The 5-point Likert scale uses five answer options, including a midpoint or neutral option, to assess a respondent’s opinions. A typical 5-point Likert scale example looks like this: 

How easy or difficult is it to sign up for our mobile app?

The 6-point Likert scale is similar to a 4-point one but offers more options to respondents. The following example demonstrates what a 6-point Likert scale may look like: 

How important or unimportant is using social media to you?

The 7-point Likert scale offers more response options to your survey takers to get a more nuanced data set. A sample 7-point Likert scale survey could look like this: 

How much do you agree or disagree that the company helps its employees grow their careers?  

The 10-point Likert scale provides 10 choices to survey respondents, allowing you to get data with more granularity and precision. The following is an example of a 10-point scale:

How important or unimportant is it for you to talk about your career growth regularly with your manager?

The Net Promoter Score® (NPS) is a famous Likert scale question commonly used to measure customer satisfaction and brand loyalty. It uses an 11-point Likert scale from 0 to 10. The NPS survey question differs from other scales as it uses a numerical scale rather than verbal descriptors.

Frequency is a common measurement for Likert scales in quantitative surveys. It is used for collecting self-reported frequency of a behavior, such as using or purchasing your product, engaging in team-building activities etc. Here’s an example of a frequency Likert scale:

In general, how often do you shop in our store?

Yes, a Likert scale is ordinal. The intervals between the values your respondents can choose are not truly equal, and so can’t be considered a set of quantitative intervals.

Likert scales capture attitudes or opinions more precisely than binary questions. For example, customers who “like the product, but are not crazy about it” can give either a “yes” or “no” answer to the binary question of “Do you like our product?” making it nearly impossible to understand the degree of preference for the product.

Likert scale questions, by comparison, improve survey data quality by allowing more accurate and nuanced answers from survey takers.

It’s important to keep each series of questions in your survey focused on the same topic. In the end, this will help you get more accurate results. Why? Because when the time comes for you to report the data, you want to analyze a score that summarizes the results from a few questions.

For example, you could ask this initial question:

And follow up with:

But here’s one question you should leave for another section of the survey:

Grouping questions about one topic together and adding up their responses to get a score–a “Quality-of-Food” score, in this case—will give you a more reliable measurement of attitudes toward the particular product, service, or event you’re researching.

Likert scales are easier for survey-takers to understand and respond to than open-ended, ranking, or “select all” questions. Therefore, respondents are less likely to experience survey fatigue and get frustrated in their survey-taking process. They will have a positive survey experience and be willing to provide their feedback again in your future surveys.

Likert scales will provide you insights into how your customers, employees, or target market think about your product, company, or service, but they do not tell you why they think so. For example, you may find out that your customers are not satisfied with your mobile app with Likert scales, but the scales don’t suggest how to change your mobile app to improve customer satisfaction.

Carefully planning the survey design will help address the “why.” For example, after you ask participants to rate their satisfaction on Likert scales, follow up with a multiple-choice or an open-ended question to inquire about the reasons they provide those ratings. Combining Likert scales with follow-up questions will give you a full picture of customer insights.

The interpretation of Likert scale points can vary between respondents. Individuals also think of the extremity of their opinions and attitudes differently. One person’s “strongly agree” might be another’s “somewhat agree.”

To mitigate the potential subjectivity issue, researchers or practitioners must make sure they choose Likert scales with the right number of scale points. More scale points could mean more nuances in data and insights, but having too many scale points also increases potential ambiguity between answer options.

In some survey topics, survey takers might intentionally choose the neutral point in Likert scales to avoid being perceived as having extremist views. For example, suppose a customer is rating different aspects of your product, service, or business on a Likert scale of 1 to 10. In that case, most of the answers will fall in the center (4-7), with only a few being rated highly (8-10) or lower (1-3).

Making sure that respondents know the survey is anonymous can help. Knowing when to introduce a neutral or midpoint option is also crucial, and it depends on the specific question being asked.

For instance, this structure recognizes the possibility that individuals may genuinely feel neutral about the experience:

Would you say that the experience had a positive or negative impact?

Net Promoter Score is a highly regarded loyalty metric companies use to collect customer feedback. An NPS survey is simple to create. It asks respondents to rate the question, “How likely is it that you would recommend this company to a friend or colleague?” on a 0 to 10 Likert scale.

The answers customers provide are classified as follows:

After an event, you can use Likert scales to gather feedback from your attendees to evaluate the success of the event. Regardless of whether the event is in-person or online, you can use event feedback surveys to understand participants’ overall experience and their sentiments about different aspects of the event. For example:

How helpful or unhelpful was the event in connecting you with people with similar interests?

Learning how easy to use and enjoyable your prospects and customers find your website is a great reason to create a survey. You want to be sure that you’re presenting your company and products in the best way possible and providing a great user experience. A Likert scale survey question to gather website feedback from your site visitors could look like this: 

How likely or unlikely are you to return to our website to find information? 

Knowing more about your customers and their habits is always helpful. It is vital for your marketing and product teams so they can tailor ads and new items to exactly what your customers want. Asking them Likert survey questions can help you get a deeper understanding of their opinions and preferences. A survey question to gather opinions from your customers might look like this: 

How important or unimportant to you is attractive packaging? 

Like we mentioned above, Likert scales are flexible. You don’t have to use a fixed survey design. Instead, you can determine how many scale points to use in your survey. 

There are many factors to consider when making a decision. Likert scales with fewer scale points are easier for respondents to read and process but will not provide as many details and nuances. 

Likert scales with more scale points give you more detailed data, but you will sacrifice some response time. They can make your respondents feel fatigued fast. They worsen the subjective interpretation of scale points too.

You will also need to decide whether to use an odd-numbered or even-numbered scale too. If making sure that survey takers provide attitudes is important to your project, then you may consider taking out the middle-point or the neutral point of the Likert scale and use an even-numbered one.

Ultimately, you will need to consider your research priorities and weigh the factors accordingly.

To maximize their effectiveness, Likert-type questions need precise phrasing. 

For instance, when asking about satisfaction with restaurant service, it's crucial to specify which aspect of service is being referred to – valets, waiters, or hosts. You also need to be clear about the aspects of service you want to evaluate, such as the speed, courtesy, or quality of food and drinks.

Being more specific in Likert scales will get you more valuable responses.

When crafting Likert scales, make sure respondents understand your intent clearly. Use descriptive words in response options to avoid confusion about relative rankings. 

This approach helps respondents navigate the scale effectively.

Bipolar constructs are those where attitudes can fall on one side or the other of a midpoint that itself is true ambivalence or neutrality. Unipolar constructs are those that lend themselves strictly to an amount and don't have a neutral midpoint–either there is the maximum amount of the attitude or none of it. 

For instance, let’s say I asked you to rate how helpful this article is. It may fall between being the most helpful article you’ve ever read and not helpful at all. From there, we can safely assume there is something in between–like “sort of” helpful. This is an example of a unipolar construct.

Statements pose a risk: most people tend to agree rather than disagree. This is because survey respondents tend to select positive response options more frequently (known as agreement or acquiescence response bias). Therefore, asking a question is more effective than making a statement.

Once you’ve created your Likert scale survey, most of your hard work is done! However, you still need to analyze the data you receive from the survey responses to measure your performance in your survey target area. 

Since Likert scales are ordinal scales, Likert scale analysis is best summarized using a median or a mode. Means/averages are not always useful. 

When analyzing Likert scale data, you want to look at the distribution of responses across scale points or categories. You can summarize the percentages of each response category and then visualize the results using bar graphs. 

Depending on the goal of your project, you can also merge Likert scale points into simpler categories. For example, suppose you gathered customer satisfaction on a 5-point Likert scale ranging from “not at all satisfied” to “highly satisfied.” In that case, you may want to get the total number of respondents who gave a “somewhat satisfied” or “highly satisfied” answer. This will tell your team the total number or percentage of people with a positive sentiment. The treatment of NPS data is also an example of categorizing scale points.

Remember, while analyzing your Likert survey data, despite it being a very accurate way of gathering data, it’s still susceptible to social desirability bias. That means people are likely to give answers they think are socially acceptable instead of being honest, especially with difficult questions. They may choose to answer as undecided or neutral options instead of their real preferences.
