When carrying out a systematic investigation, the researcher may need the respondents to rate his or her knowledge or degree of satisfaction with a particular product or service. To do this objectively, he or she may need to include different types of rating scales in the questionnaire or survey.
With a rating scale, the researcher can easily quantify respondents’ knowledge and opinion in terms of specified values which can be numerical or otherwise. A rating scale is typically used in quantitative and qualitative observation methods to evaluate different opinions about a research subject.
What is a Rating Scale?
A rating scale is a common method of data collection that is used to gather comparative information about a specific research subject. Specifically, a rating scale is a type of multiple-choice question and it allows survey respondents to assign a value to a product or service.
This method of data collection enables survey respondents to measure their feelings, perceptions, interests, and preferences. There are different types of rating scales including numerical scales, heart rating scales and Likert scales, and each of these scales has specific features that differentiate one from the other.
Types of Rating Scale
- Numerical Scale
A numeric scale is a type of rating scale that requires the respondent to provide his or her feedback in terms of numerical values. This type of rating scale equates comparative survey response options to an ordered set of numerical values so that respondents can quantify their opinions.
This type of rating scale allows the researcher to view survey responses as quantitative symbolizations. A numerical rating scale is typically used to quantify qualitative data such as pain, feelings, product satisfaction, likelihood to recommend, customer loyalty and the like.
Usually, the researcher labels the endpoints of the numerical rating scale in terms of the value that is being measured so that both ends represent the extremes of this value. Examples of numerical rating scales include Single Ease Questions and Likelihood to Recommend Questions.
Samples of a Numerical Rating Scale
- How likely are you to recommend our product or service? (1 = Very Unlikely; 5 = Very Likely)
- How easy or difficult did you find this test? (1 = Very Difficult; 7 = Very Easy)
- Likert Scale
A Likert scale is a type of rating scale that allows survey respondents to indicate how much they agree or disagree with an assertion or a statement. It is used to measure a survey respondent’s psychological disposition or attitude towards a specific subject matter.
A likert scale is typically in the form of a 5-point or 7-point rating system that allows you to objectively rate the survey respondent’s opinions, perceptions, and behaviors. It also includes a moderate or neutral rating that caters to opinions that are neither here nor there.
This type of rating scale is un-dimensional in nature and it can also be used to measure agreement, frequency, quality, likelihood, and importance. It was developed in 1932 by the social psychologist Rensis Likert and it is a useful tool for market research.
Guttman scale, Bogardus scale and, Thurstone scale are also common variations of the Likert scale.

If you wish to collect feedback in terms of numerical value, you can make use of a numerical rating scale. On the other hand, if you wish to collect data relating to a user’s experience with a product or service, you can make use of a smiley rating scale.
- A rating scale helps to simplify data collection and analysis in research.
- In quantitative observation, a rating scale can be used for comparative data analysis, especially when it has to do with market research.
- It is easy to administer and it reduces the chances of survey bias and survey response drop-out. This is because it is easy to understand and survey respondents do not need to spend a lot of time trying to decipher the focus of the survey?
- Using a rating scale for data collection helps you to save time; especially when creating an online survey using data-gathering platforms like Formplus.
- A rating scale is also a convenient method of opinion sampling.
Disadvantages of a Rating Scale
- It is subject to data limitations. A rating scale does not allow you to gather specific data about a respondent’s experiences. While it may reveal a respondent’s overall disposition to a product or service, it doesn’t collect any information about the reason for such behavior
- A rating scale addresses the focus of the research comparatively rather than individually. Hence, while it can tell you about the feeling and perceptions of the respondent, it does not let you in on the reason for this perception.
- A rating scale is subject to limited reliability. This means that it cannot be totally relied on in research; especially in qualitative research.
- It is also subject to substantial variations.
- Because it is easy to use, a rating scale can easily be misinterpreted; especially when the data analysis process is not handled by a professional.
- It is not an effective business management tool.
Conclusion
When choosing a rating scale, it is important to take your research process and the overall purpose of the systematic investigation into consideration. This is because some rating scales are better suited for certain types of research than others, for example, a numerical rating scale is better suited for quantitative research.
There are different types of rating scales including the Likert scale, radiofrequency scale, and the heart rating scale. You can create these different scales easily in the Formplus builder by clicking on or dragging and dropping your preferred rating scale fields into your form.
