The 7-point Likert scale is a widely used method of measuring agreement or disagreement in social science research. The scale ranges from „strongly disagree“ to „strongly agree“ and includes five intermediate options. Here are seven key points to keep in mind when using the 7-point Likert scale for agreement in your research:
1. Clear wording and instructions are important.
The Likert scale questions should be worded in a way that is clear, concise, and easy to understand. Additionally, instructions should clearly explain how respondents should answer the questions.
2. The order of the scale matters.
The order of the scale options should be consistent throughout the survey. Typically, the „strongly disagree“ and „strongly agree“ options are placed at opposite ends of the scale.
3. Avoid using a neutral option.
Some researchers include a neutral option (such as „neither agree nor disagree“) in their Likert scales. However, this can lead to artificially inflated agreement rates and may not accurately reflect the true opinions of respondents.
4. Use odd numbers of scale points.
Research has shown that odd-numbered scales (such as the 7-point Likert scale) are more reliable than even-numbered scales because they force respondents to choose one side or another, rather than allowing for a „middle ground“ option.
5. Keep response options consistent.
All questions in a Likert scale should have the same response options, and these response options should be clearly labeled and consistent throughout the survey.
6. Analyze the data carefully.
After collecting survey data, take care to analyze the results carefully. Consider using descriptive statistics, such as means and standard deviations, to better understand the patterns of responses.
7. Remember that Likert scales have limitations.
While the Likert scale is a useful tool for measuring agreement and disagreement, it has some limitations. For example, it may not capture the full range of opinions on a given topic. Additionally, the scale may be influenced by factors such as social desirability bias. As such, it is important to use the Likert scale in conjunction with other research methods to gain a more comprehensive understanding of attitudes and opinions.
