In addition to measuring match data, Likert scales can also measure other variations such as frequency, quality, meaning and probability, etc. Test your survey on a small pool of participants representing the largest group you want to learn more about and analyze the data. If you receive additional credits, you can perform an article analysis. A Likert scale is a very fast and easy-to-achieve survey, which can be sent on all modes of communication. They offer a universal method of collecting data, which means it is easy to understand. When working with quantitative data, it`s easy to draw conclusions, reports, results and diagrams of responses. A 7-point scale offers 7 different response options related to an agreement that would be clear enough for respondents without confusing them. Generally, it contains a moderate or neutral center, and the 7-point Likert scales are known to be the most accurate of Likert`s scales. These questions are used to measure customer satisfaction.
Follow best practices to create investigative questions. Personalize your audience, use their language and avoid double or long, complicated statements. One Likert element is only a statement that the respondent must assess by giving it a quantitative value for each type of subjective or objective dimension, the degree of agreement/disagreement being the most commonly used dimension. Well-designed Likert elements have both „symmetry“ and „balance.“ Symmetry means that they contain the same number of positive and negative positions whose respective distances above the „neutral“/zero value are bilaterally symmetrical (whether this value is presented as a candidate or not). Balance means that the difference between the different candidate values is the same, so both quantitative and average comparisons are valid for items containing more than two candidate values.  Most researchers agree that you should use at least a 5-point Likert scale. But other studies show that the more choices, the less respondents use the middle or neutral category. It seems clear that a 7-point Likert scale is approaching the upper limits of reliability – so adding other options will probably give you less good, not better, data on the Likert scale. The five categories of responses are often considered an interval measure.
However, this can only be the case if the intervals between the scale points correspond to empirical observations in the metric sense.
