Likert scale questions are used in many types of surveys, whether you want to know how your employees think about their work or what your customers think of your newest product. For example, each of the five (or seven) responses would have a numerical value that would be used to measure the parameter being studied. Like star rating, respondents can rate a statement on a visual cardiac scale with the question of cardiac rating. A weight is assigned to each symbol of the heart on the scale. The format of a typical five-level Likert element could be for example: a good Likert scale, as above, shows a symmetry of categories around a center with clearly defined language qualifications. In such a symmetric scale, equidistant attributes are usually observed more clearly or, at the very least, deduced. When a Likert scale is symmetrical and equidistant, it behaves more like a measurement at regular intervals. While a Likert scale is actually ordinal, if it is well represented, it can nevertheless approach an interval measure. This can be beneficial, because if it were only treated as an ordinal scale, some valuable information could be lost if the “distance” between the Likert elements was not available.
The important idea is that the appropriate type of analysis depends on how the Likert scale was presented. Pay attention to adjectives. If you use words to ask for concepts in your survey, you need to be sure that people understand exactly what you mean. Your response options should contain descriptive words that are easy to understand. .
