Learn to write and develop effective Likert scale questions for your market research using tips from this best practice guide, especially useful for concept validation.


Here are some tips and tricks for great Likert scale questions

1. Write Clear Questions

Likert questions should be phrased as factually and specifically as possible to encourage more accurate results. Remember, respondents will only answer the exact question that they are asked.

Consider a customer satisfaction survey. The question “How satisfied are you with this product?” could receive significantly different answers than if you asked, “How satisfied are you with the price of this product?" For this reason, it is important to acknowledge which aspect you are seeking feedback on, e.g. overall satisfaction, price, value, effectiveness, packaging, leaving no room for individual interpretation.

2. Keep Adjectives Consistent

Pay close attention to the use of adjectives in Likert questions to ensure that respondents can clearly understand the meaning of each option. Each adjective should have a clear position on the scaling, from highest to lowest. Use “Extremely” for both ends of the scale (e.g. “Strongly agree” “Strongly disagree”, set a neutral midpoint (e.g. “Neither agree nor disagree”), and fill moderate ratings with the same adjectives (e.g. “Somewhat disagree”, “Somewhat agree”).

3. Consider Unipolar vs. Bipolar Scale

According to the Knowledge Base, Likert scales are always unidimesional (i.e. they measure a single dimension of something). But they can be either bipolar or unipolar, i.e. they have either two ends or one:

  • Use bipolar scales when you want respondents to answer on either a positive or negative side of neutrality. For example, the question “How likely are you to purchase this product” would range from “Extremely Unlikely” to “Extremely likely” with “Undecided” as the midpoint.

  • Unipolar scales are easier for respondents to follow, operating from a scale of zero to extreme. For example, the question “How appealing does this product look to you?” could have options ranging from “Not appealing at all” to “Extremely appealing”.

4. Use Questions Rather Than Statement

To avoid acquiescence bias (AKA ‘Yes’ bias) caused by respondents’ tendency to answer questions agreeably or positively. Question-wording plays a significant role in how your respondents will answer a question, so you should be mindful of phrasing Likert questions. Be mindful of language – avoid leading questions and opt for open-ended questions instead. For example, asking “How much do you agree with the following statement: “I am satisfied with the quality of this product”?” is more likely to encourage a biased response than “How satisfied are you with the quality of this product?”

Other tips

Use flip scales. Flip scales obtain more accurate survey responses by preventing bias. Instead of displaying all answer options in ascending order (e.g. 1 = very dissatisfied, 5 = very satisfied), you can use a flip scale for some questions to avoid repetition (e.g. 1 = very satisfied, 5 = very dissatisfied).

Seek diverse answers. A good Likert question should produce a broad range of answers. Whilst it may seem favourable for everybody to agree your product is perfect, you will be missing out on valuable feedback from consumers about areas for improvement.

Review your questions. Ask others to read through your questions and grade them before launching your study to ensure the phrasing is clear and to check for any spelling or grammar mistakes. You should also keep your tone lively and avoid repetitive language to keep respondents engaged.

FAQs

What is a Top-2-Box (T2B)?

A top-2-box score summarises positive responses from a Likert scale survey question, making it faster to interpret results.

Looking at the raw output from a Likert scale question, it can be hard to quickly identify which options are the most preferred.

Example output of likert scale questions

The top 2 box score represents the proportion of respondents that selected either of the top 2 responses of the scale. We see in this example, “Somewhat important” and “Extremely important” are the top two options.

Finding the top results from a likert question

The top 2 box score can be calculated as the percent of respondents that chose either of the top two options.

Top 2 box calculated

While the top 2 box score is often used for 5-point Likert scale questions, different variations can also be used, such as the top 3 box for a 7-point Likert scale question.

What is a Top-1-Box (T1B)?

T1B is similar to T2B, but it is the percentage of responses for only the most positive option.
