Why 7-Point Likert Scale Familiarity is Important for Researchers

Have you ever been asked to complete a survey or questionnaire that asked you to rate your level of agreement on a scale of 1 to 5? The chances are that you encountered a Likert scale. A Likert scale is a measurement tool that allows researchers to collect data on people’s attitudes, opinions or beliefs. It is widely used in academic and market research to explore and measure these subjective elements of human behaviour.

But what happens when a researcher needs to capture more nuanced data? Sometimes researchers need to capture a more granular understanding of attitudes or opinions which require more detailed responses. This is where the 7-point Likert scale comes in. The 7-point scale provides an additional level of granularity that allows researchers to capture more nuanced data points. In this article, we explore how 7-point Likert scale familiarity is important for researchers and how it can impact the accuracy of research.

The Benefits of Using a 7-Point Likert Scale

1. Greater Precision: The additional points on the scale offer respondents a greater level of granularity when rating their level of agreement or disagreement. This granularity provides researchers with a more precise measurement of the participant’s attitudes or opinions.

2. Reduced Uncertainty: The 7-point scale can reduce the uncertainty that can arise when using a 5-point scale. Respondents can find it challenging to differentiate between an ‘agree’ or ‘strongly agree’ rating. But with more options, the chances of respondents selecting the wrong option decreases, leading to more accurate results.

3. Increased Sensitivity: The 7-point scale has been shown to be more sensitive in detecting real changes in opinions or attitudes. This sensitivity can be important, especially when making comparisons over time or between different groups.

Examples of 7-Point Likert Scale Usage

A study by the University of Cambridge found that the 7-point scale was more effective at detecting changes in participants’ attitudes towards climate change. The research compared the responses of participants using both the 5 and 7-point scales. The research found that the 7-point scale was better suited to capture the nuances of changes in attitudes over time.

Research in the field of customer experience also found that the 7-point scale was superior to the 5-point scale. The researchers discovered that the 7-point scale was better able to identify areas of low satisfaction, which were less apparent using the 5-point scale.

Conclusion

The 7-point Likert scale is a valuable tool for researchers looking to capture more nuanced data. It provides a greater level of specificity, reduces uncertainty and is more sensitive in detecting changes over time. By being familiar with the 7-point scale and understanding its benefits, researchers can improve the accuracy of their work and provide more meaningful insights.
