Have you ever participated in a survey that asked you to rate your agreement on a scale of 1 to 5? If yes, then you have experienced the Likert Scale research method. This research method is commonly used in fields such as psychology, sociology, and education to gather data on people’s attitudes, opinions, and perceptions towards certain topics. It is an easy and efficient way to collect quantitative data with a predetermined set of responses.
The Likert Scale research method gets its name from its creator, Rensis Likert, who developed it in the 1930s. The scale consists of a series of statements that participants are asked to rate on a 5 or 7-point scale. The responses are often labeled with words such as “strongly agree,” “agree,” “neither agree nor disagree,” “disagree,” and “strongly disagree.” Researchers use this data to analyze participants’ perceptions of the topic being studied and determine the prevalence of certain attitudes or opinions.
One important aspect of the Likert Scale research method is that it measures attitudes and perceptions, not behavior. This means that participants may hold certain attitudes or opinions but may not necessarily act on them in their daily lives. Nonetheless, the Likert Scale is a valuable tool for researchers because it provides quantitative data that can be analyzed using statistical methods. So, the next time you participate in a survey with a series of statements to rate, you’ll know that you are contributing to Likert Scale research.
What is the Likert Scale?
The Likert Scale is a psychometric scale used in research studies. It is one of the most popular rating scales used in quantitative research to measure opinions, attitudes, preferences, and behaviors.
The scale was developed by Rensis Likert, an educator and social psychologist, in 1932. The Likert Scale is easy to administer, and it is also easy to analyze. This is why it has remained popular among researchers for decades.
- The scale consists of a set of statements, and the survey participants are asked to rate each statement on a scale of 1 to 5, where 1 means strongly disagree and 5 means strongly agree.
- It is a five-point rating scale, but it can be adjusted according to the researcher’s needs. There may be seven or nine-point scales as well.
- The scale can be used to measure a variety of constructs, such as personality traits, customer satisfaction, employee motivation, and many more.
The Likert Scale has become an important tool in marketing research, political science, psychology, and other fields that require a quantitative approach. It is an effective way to measure the level of agreement or disagreement of people towards a given topic or construct. Researchers use the scale to measure attitudes towards products, services, political decisions, and social issues, among others.
The History of Likert Scale
The Likert Scale, developed by Rensis Likert in 1932, is a psychometric scale that is commonly used in research. It is a type of rating scale that measures attitudes or opinions on a range of options. The Likert Scale is named after its creator, who was an American social psychologist.
The Likert Scale has become one of the most popular tools for measuring attitudes in both social and psychological research. It is used in a wide range of fields, including education, business, healthcare, and politics. The scale provides researchers with a simple way to assess the intensity of attitudes towards a particular statement or object.
Features of the Likert Scale
- The scale consists of a series of statements relating to the attitude or opinion being measured.
- The statements are rated on a numerical scale, typically ranging from 1 to 5, with 1 representing the lowest level of agreement and 5 representing the highest level of agreement.
- The Likert Scale assumes that attitudes can be measured on a continuous scale, rather than as a discrete set of categories.
- The scale allows researchers to capture more nuanced responses from respondents than dichotomous scales, which only allow for binary (agree/disagree) responses.
The Likert Scale in Practice
The Likert Scale has been used in countless research studies since its inception in 1932. One of the reasons for its popularity is its simplicity, ease of use, and flexibility. Researchers can easily create their own Likert Scale questions and tailor them to their specific research goals.
One example of a recent study that used the Likert Scale is a paper investigating attitudes towards breast cancer screening in Africa. The researchers used a series of Likert Scale questions to assess participants’ attitudes towards breast cancer screening, as well as their knowledge and beliefs about the disease.
The Advantages and Disadvantages of the Likert Scale
| Advantages | Disadvantages |
|---|---|
| – The scale is easy to administer and can be completed quickly – The scale can be used to measure a wide range of attitudes and opinions – The scale provides a continuous measure of attitudes, allowing for more nuanced responses – The scale is flexible and can be tailored to specific research goals |
– Respondents may not take the questions seriously, leading to unreliable results – The scale assumes that attitudes can be measured on a continuous scale, which may not always be the case. – The scale is subjective and relies on the interpretation of respondents |
Overall, the Likert Scale remains a popular tool for measuring attitudes and opinions in both social and psychological research. Its simplicity, ease of use, and flexibility make it a versatile tool for researchers across a range of disciplines.
Characteristics of Likert Scale questions
When conducting research, it is important to choose the appropriate scale to measure variables. One of the most popular types of scales used in research is the Likert Scale, which measures attitudes, opinions, and perceptions. Here are some key characteristics of Likert Scale questions:
- Multiple response options: Likert Scale questions typically have between five and seven response options, ranging from strongly agree to strongly disagree. The neutral option is also included to capture those who are ambivalent towards the statement.
- Ordered response options: The response options are ordered in terms of strength of agreement or disagreement, with the strongest agreement or disagreement option placed first and the weakest placed last.
- Bipolar constructs: Likert Scale questions are bipolar constructs, meaning they measure two opposing constructs. For example, a Likert Scale question might measure a person’s agreement or disagreement with a statement, such as “I believe in climate change.”
Benefits of using Likert Scale questions
Likert Scale questions have several benefits that make them a popular choice for researchers:
- Easy to administer: Likert Scale questions are easy to administer and can be used in a variety of settings, including online surveys, paper surveys, and interviews.
- High reliability: Likert Scale questions have high reliability, meaning that they consistently measure what they are intended to measure.
- Easy to analyze: The responses to Likert Scale questions can be easily analyzed using statistical software, making it easy to draw conclusions from the data.
Common pitfalls of using Likert Scale questions
While Likert Scale questions are widely used and have many benefits, there are also some common pitfalls to be aware of:
- Interpretation issues: Respondents may interpret the response options differently, leading to biased results. It is important to ensure that the response options are clear and unambiguous.
- Social desirability bias: Respondents may answer Likert Scale questions in a socially desirable way, rather than providing their true opinions. Researchers can minimize this bias by ensuring anonymity of responses.
- Sampling issues: Likert Scale questions are only as good as the sample being surveyed. Researchers should ensure that the sample is representative of the population being studied.
Example of a Likert Scale question
Here is an example of a Likert Scale question:
| Statement | Strongly agree | Agree | Neither agree nor disagree | Disagree | Strongly disagree |
|---|---|---|---|---|---|
| I believe in the effectiveness of vaccination. | X |
In this example, respondents are asked to indicate their level of agreement or disagreement with the statement “I believe in the effectiveness of vaccination”. The response options range from strongly agree to strongly disagree.
Advantages of using the Likert Scale
When it comes to conducting research, the Likert scale is a widely popular instrument used by researchers to measure attitudes and opinions of their participants. The Likert scale is a type of survey question that uses a rating scale to measure responses. Participants are asked to indicate their agreement or disagreement with a statement using a scale that ranges from strongly agree to strongly disagree.

Disadvantages of using the Likert Scale
While the Likert Scale is one of the most common methods of measuring attitudes, opinions, and behaviors, it is not without its shortcomings. Here are five key disadvantages of using the Likert Scale:
- Difficulty in interpretation: One of the primary issues with the Likert Scale is that the results can be difficult to interpret. While the numerical ratings make the data easy to collect and analyze, the scale does not provide any context or explanation for the responses.
- Social desirability bias: Another disadvantage of the Likert Scale is that respondents may be influenced by the desire to present themselves in a positive light. This can result in bias towards socially desirable responses, rather than honest or accurate ones.
- Restrictions on variability: The Likert Scale typically uses a limited number of response options (e.g. 5 or 7), which can restrict the variability of responses and limit the precision of the data collected.
- Lack of standardization: There is no standardized format for the Likert Scale, which can lead to variations in response options, question wording, and overall structure. This can make it difficult to compare results between studies or even within different parts of the same study.
- Assumes linear scale: The Likert Scale assumes that the intervals between response options are equal, but this may not always be the case. For example, the difference between “strongly agree” and “agree” may not be the same as the difference between “disagree” and “strongly disagree.”
Conclusion
While the Likert Scale is a useful tool for measuring attitudes and opinions, it is important to be aware of its limitations and potential biases. Researchers should carefully consider their research question and the characteristics of their sample population when deciding whether the Likert Scale is the most appropriate tool to use.
Additionally, researchers can mitigate some of the limitations of the Likert Scale by using other research methods, such as open-ended questions, focus groups, or observations, to provide additional context and depth to their data.
| Advantages | Disadvantages |
|---|---|
| Widely recognized and accepted | Difficulty in interpretation |
| Easy to administer and analyze data | Social desirability bias |
| Can quantitatively measure attitudes and opinions | Restrictions on variability |
| Can be applied in various settings | Lack of standardization |
| Cost-effective | Assumes linear scale |
Ultimately, choosing the most appropriate research method depends on the specific research question, the sample population, and the desired level of depth and precision in the data collected.
Types of Likert Scales
In the field of research, there are many types of Likert scales used to measure the attitudes, beliefs, and opinions of respondents. Each type of Likert scale has its own unique strengths and weaknesses, and the type of scale that is most appropriate for a particular study depends on a variety of factors, such as the research questions being asked and the type of data that is being collected. Here are six types of Likert scales that are commonly used in research:
- 5-Point Likert Scale: This type of Likert scale is the most commonly used and has five response options, ranging from strongly agree to strongly disagree. This scale is easy to administer and analyze, and it is appropriate for measuring relatively simple concepts.
- 7-Point Likert Scale: This type of Likert scale includes seven response options, ranging from strongly agree to strongly disagree, with a neutral option in the middle. This scale is useful for measuring more complex concepts and can provide more nuanced data than a 5-point scale.
- 10-Point Likert Scale: This type of Likert scale includes ten response options, ranging from strongly agree to strongly disagree, with a neutral option in the middle. This scale is appropriate for measuring very complex or abstract concepts, but it can be more difficult to administer and analyze than a 5- or 7-point scale.
- Frequency Likert Scale: This type of Likert scale is used to measure how frequently a behavior or attitude occurs, rather than how strongly it is held. Respondents are asked to indicate how often they engage in a particular behavior or hold a particular attitude, with response options ranging from never to always.
- Importance Likert Scale: This type of Likert scale is used to measure the importance of a particular concept or idea to the respondent. Respondents are asked to indicate how important a particular concept is to them, with response options ranging from not at all important to extremely important.
- Agreement Likert Scale: This type of Likert scale is used to measure the level of agreement or disagreement with a particular statement. Respondents are presented with a statement and asked to indicate how strongly they agree or disagree with it, with response options ranging from strongly agree to strongly disagree.
The Likert Scale Table
Below is a table that summarizes the types of Likert scales and their characteristics:
| Likert Scale Type | Number of Response Options | Used to measure |
|---|---|---|
| 5-Point | 5 | Relatively simple concepts |
| 7-Point | 7 | Complex concepts |
| 10-Point | 10 | Very complex or abstract concepts |
| Frequency | Multiple options for frequency | Frequency of behavior or attitude |
| Importance | Multiple options for importance | Importance of concept or idea |
| Agreement | Multiple agreement options | Level of agreement or disagreement with statement |
By understanding the strengths and weaknesses of each type of Likert scale, researchers can choose the most appropriate scale for their study and ensure that they are collecting accurate and reliable data.
How to analyze data from a Likert Scale
Conducting a survey using a Likert scale is a popular method for measuring attitudes, opinions, and experiences. However, analyzing the results can be a daunting task. Here are some tips on how to analyze data from a Likert scale:
- 1. Calculate the total score: Start by summing up the points for each respondent. For example, if the Likert scale has 5 points, you can assign 1 for “strongly disagree,” 2 for “disagree,” 3 for “neutral,” 4 for “agree,” and 5 for “strongly agree.” The scores for each respondent can be added up to calculate a total score that ranges from the minimum possible score (e.g. 10 for a 2-item survey with 5-point Likert scale) to the maximum possible score (e.g. 50 for a 10-item survey with 5-point Likert scale).
- 2. Calculate the mean score: The total score can be converted to a mean score by dividing it by the number of items in the survey. The mean score provides a more intuitive and interpretable metric. For example, if the total score is 40 and the survey has 8 items, the mean score is 5.0 (40/8).
- 3. Calculate the mode and median: The mode is the most frequently occurring response, while the median is the middle response when all responses are arranged in order. Mode and median can provide additional insights into the central tendency of the responses.
- 4. Calculate the standard deviation: The standard deviation measures the variability of the responses. A high standard deviation indicates that the responses are dispersed widely around the mean, while a low standard deviation indicates that the responses are clustered closely around the mean.
- 5. Conduct a frequency analysis: A frequency analysis of the responses can reveal the proportion of respondents who selected each option. This can be presented in a table or a chart, such as a bar plot or a pie chart.
- 6. Conduct a correlation analysis: A correlation analysis can reveal the relationships between different items or factors in the survey. For example, if the survey includes multiple items that measure the same construct, such as customer satisfaction, a correlation analysis can reveal how strongly each item is related to the others.
- 7. Conduct a factor analysis: A factor analysis can reveal the underlying dimensions or factors that explain the covariation among the items. This can help identify the main themes or constructs that the survey aims to measure.
By analyzing the data from a Likert scale using these methods, you can gain valuable insights into the attitudes, opinions, and experiences of your target audience.
| Method | Advantages | Disadvantages |
|---|---|---|
| Total score | Easy to calculate and interpret | May lose information about individual responses |
| Mean score | Provides a more interpretable metric | Sensitive to outliers or extreme values |
| Mode and median | Provide additional insights into central tendency | May not capture the full range of variability |
| Standard deviation | Measures variability and dispersion | May be affected by the number of response categories |
| Frequency analysis | Provides a visual summary of the responses | May oversimplify the complexity of the responses |
| Correlation analysis | Reveals the relationships among items | Assumes linear relationships and may not capture non-linear or complex relationships |
| Factor analysis | Reveals the underlying dimensions or constructs | Requires prior knowledge or theoretical frameworks |
Each method has its own advantages and disadvantages, and the choice of method may depend on the research questions, the nature of the data, and the intended audience. By combining multiple methods, you can gain a more comprehensive and nuanced understanding of the data from a Likert scale.
