Versatile and reliable, this Swiss Army knife of sentiment analysis can give you insights into everything from customer satisfaction to employee engagement.

If you’re eager to learn how to create, use, and analyze Likert scales effectively, you’re in the right place. Ready? Let’s go!

What is a Likert Scale?

A Likert scale is a psychometric scale commonly used in questionnaires to measure attitudes, opinions, or perceptions. Unlike simple yes/no questions, a Likert scale allows respondents to express varying degrees of agreement, satisfaction, frequency, or importance.

Named after its inventor, psychologist Rensis Likert, this scale has become a cornerstone of survey research and social sciences. You’ll often see it in the form of a 5-point or 7-point scale, but in principle, it can have more or fewer points depending on the depth of insight you need.

For example, when asking a question about customer satisfaction, a typical Likert scale might look like this:

  • Strongly Disagree
  • Disagree
  • Neutral
  • Agree
  • Strongly Agree

This can be a game-changer for researchers and businesses looking to dive deeper into public opinions without the mess of ambiguity.

Benefits of Using Likert Scales

Why are Likert scales so popular? Simple—because they’re easy to use and interpret! Here are some juicy benefits:

  • Ease of Use: Respondents can quickly grasp the meaning behind the scale, making it user-friendly.
  • Nuanced Responses: A Likert scale allows for a spectrum of opinions rather than a simple yes or no, capturing the complexity of feelings.
  • Quantifiable Data: Unlike open-ended questions, Likert scales provide easily quantifiable data, which makes analysis a breeze.
  • Consistency: It offers a consistent way to measure opinions across a variety of topics, making comparisons simple.
  • Flexibility: You can use it to measure anything from satisfaction levels to attitudes about social issues.

Common Usage Scenarios for Likert Scales

You’ll find Likert scales in a wide range of fields, from market research to psychology. Here are just a few places they show up:

Really, anytime you need to measure how people feel about something, the Likert scale has you covered.

Designing Effective Likert Scale Surveys

Creating a robust Likert scale survey requires attention to detail. Follow these guidelines to maximize the quality of your data:

  • Use a Balanced Scale: Ensure there are equal numbers of positive and negative options. For example, a five-point scale provides a neutral midpoint, while a four-point scale forces a choice.
  • Label All Points Clearly: Ambiguity can skew results. Clearly define what each point on the scale represents.
  • Use Simple and Clear Language: Avoid jargon or complicated phrasing to prevent confusion.
  • Consider Scale Length: While five- or seven-point scales are most common, some surveys may benefit from broader or narrower scales depending on the level of detail needed. For example, a food delivery service that wants feedback on customer satisfaction may require just one question, while a wellness app that wants insights on user behavior may ask more questions pertaining to its features.
  • Avoid Leading Questions: Ensure questions are unbiased to collect accurate data. For example, avoid saying “Don’t you agree that our customer service is excellent?” and choose a neutral question instead, like “How would you rate our customer service?”
  • Keep Scales Consistent: If using multiple scales within a survey, try to maintain consistency in the format to avoid cognitive overload.
  • Test Your Survey: Conduct a pilot survey to check for clarity and effectiveness.

Likert Scale Examples

Let’s take a look at a few Likert scale examples to illustrate how this works:

Example 1: Customer Satisfaction

  • I am satisfied with the quality of the product.Strongly Disagree | Disagree | Neutral | Agree | Strongly Agree

Example 2: Employee Engagement

  • I feel motivated to do my best work at this company.Strongly Disagree | Disagree | Neutral | Agree | Strongly Agree

Notice how each statement is clear, focused, and designed to gauge a specific feeling or opinion.

How to Analyze Likert Scale Data

Now, the fun part—analysis! With Likert scale data, you’re working with ordinal data, which means it has a defined order but the distances between points may not be equal. Here are a few common ways to analyze this data:

  • Descriptive Statistics: Start by calculating the mean (average) score to get a sense of general sentiment. You can also calculate the mode to see the most common response.
  • Frequency Distribution: A simple bar or pie chart can help you visualize how respondents are spread across different points on the scale.
  • Cross-tabulation: If you want to compare responses from different groups, cross-tabulation can reveal interesting trends.
  • Correlation Analysis: Measure the relationship between multiple items or questions.
  • Trend Analysis: Track changes over time to identify improvement areas.
  • Reliability Analysis: If your survey includes multiple Likert scale questions to measure the same concept, you can check the reliability of your data using Cronbach’s alpha.

Different Types of Likert Scales

While the 5-point Likert scale is the most common, you can tweak it to suit your needs. Here are some variations:

  • 5-point scale: Strongly Disagree, Disagree, Neutral, Agree, Strongly Agree
  • 7-point scale: Adds more nuance between the extremes (e.g., “Somewhat Agree,” “Somewhat Disagree”)
  • 10-point scale: Offers even more granularity (like a rating scale from 1 to 10).
  • Bipolar Scales: Measures two opposing sentiments, such as satisfaction vs. dissatisfaction.

Common Likert scales that cater to different survey objectives include:

  • Agreement Scale: Measures the level of agreement with a statement.
    • Example: “The product meets my expectations.”Strongly Disagree | Disagree | Neutral | Agree | Strongly Agree
  • Frequency Scale: Gauges how often a behavior or experience occurs.
    • Example: "How often do you use our product?"Never | Rarely | Sometimes | Often | Always
  • Importance Scale: Measures the significance of various aspects.
    • Example: “How important is customer support to you?”Not Important | Somewhat Important | Neutral | Important | Extremely Important
  • Satisfaction Scale: Evaluates satisfaction levels with a service or experience.
    • Example: “How satisfied are you with our service?” Very Dissatisfied | Dissatisfied | Neutral | Satisfied | Very Satisfied
  • Likelihood Scale: Assesses the probability of a particular action or outcome.
    • Example: “How likely are you to recommend our service to a friend?”Very Unlikely | Unlikely | Neutral | Likely | Very Likely
  • Quality Scale: Measures perceived quality of a product or service.
    • Example: “How would you rate the quality of our product?” Poor | Below Average | Average | Good | Excellent

Challenges and Limitations of Likert Scales

While Likert scales are bursting with potential, they do come with hurdles. For instance, respondents may choose the midpoint to avoid commitment, leading to less insightful data. It’s essential to craft your statements carefully to encourage genuine responses. Here are a few things to keep in mind:

  • Central Tendency Bias: Respondents might avoid the extremes ("Strongly Agree" or "Strongly Disagree") and gravitate toward the middle.
  • Acquiescence Bias: Some respondents might agree with every statement just to avoid thinking too much about their answers.
  • Misinterpretation of Scales: Respondents may interpret the scale differently, especially if they’re unfamiliar with the survey format.
  • Lack of Depth: While Likert scales provide great quantitative data, they don’t explain the “why” behind a person’s opinion.

Best Practices for Using Likert Scales

To get the most out of your Likert scales, here are a few best practices:

  • Keep Statements Clear and Neutral: Avoid leading or loaded questions. The goal is to get honest, unbiased responses.
  • Balance Your Scale: Try to offer an equal number of positive and negative options (e.g., two negative and two positive, with a neutral point in the middle).
  • Use a Balanced Sample: Ensure that your survey reaches a diverse group of people so your results are more representative.
  • Test Your Scale: Before sending it out to your target audience, test your Likert scale on a small group to see if the wording and structure are working as you intended.
