The Fundamentals of Likert Scales

What is a Likert scale?

A Likert scale is a powerful tool used in surveys to measure attitudes, opinions, and perceptions. It's a type of psychometric scale that allows respondents to indicate their level of agreement or disagreement with a statement ^[1]. You'll often see Likert scales in customer satisfaction surveys, employee engagement questionnaires, and market research studies ^[2].

Typically, a Likert scale consists of 5 or 7 points, ranging from one extreme attitude to another.

For example, you might see options like "Strongly Agree," "Agree," "Neutral," "Disagree," and "Strongly Disagree" ^[2]. This structure gives you a more nuanced understanding of people's opinions compared to simple yes/no questions.

History and development

The Likert scale gets its name from Rensis Likert, an American psychologist who developed this method in the 1930s ^[3].

Likert was on a mission to create a more efficient way of evaluating subjective responses to various statements. He realized that traditional methods often lacked clarity and accuracy, making data analysis tricky ^[3].

In 1932, Likert introduced his revolutionary 7-point bipolar agreement scale ^[3]. This scale has since become one of the most widely-used tools in social science research, second only to the simple yes/no dichotomous scale ^[3].

Common applications in research

You'll find Likert scales used across various fields, including:

1. Psychology and sociology
2. Market research
3. Customer satisfaction surveys
4. Employee engagement studies
5. Educational assessments

In medical education, for instance, Likert-type scales are frequently used for end-of-rotation trainee feedback and faculty evaluations ^[4]. They're also handy for measuring the effectiveness of educational interventions ^[4].

What makes Likert scales so popular? They're versatile and easy to understand. You can use them to measure agreement, quality, importance, frequency, or even probability ^[1]. Plus, they provide a balance between getting detailed information and keeping the survey user-friendly.

Types of Likert Scale Questions

Likert scales are versatile tools that can measure various aspects of people's attitudes and opinions. Let's explore the different types of Likert scale questions you can use in your surveys to gather meaningful insights.

Agreement scales

The classic Likert scale measures the level of agreement with a statement ^[5]. You'll typically see options ranging from "Strongly Agree" to "Strongly Disagree" ^[5]. For example:

How much do you agree with the statement: "Our customer service exceeded your expectations"?

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

This type of scale helps you gage how strongly your customers feel about specific aspects of your product or service.

Frequency scales

When you want to know how often something occurs, frequency scales come in handy ^[2]. These scales use options like:

• Always
• Often
• Sometimes
• Rarely
• Never

For instance, you might ask: "How often do you seek assistance from our customer support team?" This information can help you understand usage patterns and identify areas for improvement.

Importance scales

To measure how much value respondents place on different aspects, use importance scales ^[2]. A typical importance scale might look like this:

• Very Important
• Important
• Moderately Important
• Slightly Important
• Not Important

This type of scale is great for prioritizing features or understanding what matters most to your customers.

Quality scales

Quality scales help you assess how well something performs or how good something is ^[2]. A common quality scale includes options like:

• Excellent
• Good
• Fair
• Poor
• Very Poor

You could use this to ask: "How would you rate the quality of our product?"

Likelihood scales

When you want to predict future behavior or gage potential actions, likelihood scales are your go-to ^[2]. These scales often use options like:

• Definitely
• Probably
• Possibly
• Probably Not
• Definitely Not

For example: "How likely are you to recommend our product to a friend?"

By using these different types of Likert scale questions, you can gather nuanced data about your customers' attitudes, behaviors, and preferences. Remember, the key is to choose the scale that best fits the information you're trying to uncover.

Best Practices for Creating Likert Scale Surveys

Determining the optimal scale length

When it comes to creating effective Likert scale surveys, choosing the right scale length is crucial. Most studies don't strongly favor either 5-point or 7-point scales, but some research suggests that 7-point scales might be better for respondents with higher cognitive abilities, while 5-point scales work well for the general public ^[5].

Interestingly, a European study recommended using 5-point scales for better data quality compared to 7 or 11-point scales ^[2]. This aligns with the idea that 5-point scales are more suitable for the general public.

When deciding between different scale lengths, keep in mind:

1. Fewer scale points are easier for respondents to process but provide less detailed data.
2. More scale points offer more nuanced data but can lead to respondent fatigue.
3. Consider using an even-numbered scale if you want to avoid neutral responses.

Remember, a 5-point Likert scale is often optimal for most items and businesses, providing high accuracy without being too time-consuming for customers ^[6].

Writing effective statements or questions

To get valuable insights from your Likert scale survey, you need to craft clear and unbiased questions. Here are some tips to help you write effective statements or questions:

1. Be clear and concise: Use simple language that everyone can understand the same way ^[2].
2. Stay neutral: Avoid leading respondents to a particular answer. For example, instead of asking, "Don't you think our customer service is great?" try "How would you rate our customer service?" ^[2]
3. Focus on one idea at a time: Each statement should measure only one specific aspect or opinion ^[2].
4. Be specific: Vague statements can lead to ambiguous responses. Make sure your questions are clear regardless of the respondent's background ^[2].

Balancing positive and negative items

To create a well-rounded survey and minimize bias, it's important to balance positive and negative items. Here's how you can achieve this:

1. Use positive and negative indicators for balance. For every positively worded statement, include a negatively worded counterpart later in the questionnaire ^[6].
2. For example, if you have the statement, "The variety of options online overwhelms me," you should also have an item like, "I appreciate the wide selection online shopping has to offer." ^[6]
3. This approach helps ensure that your questions are clear and the responses are reliable. People who agree with the positive statements should disagree with the negative ones, and vice versa ^[6].

By following these best practices, you'll be well on your way to creating effective Likert scale surveys that provide valuable insights for your business.
