Connect and share knowledge within a single location that is structured and easy to search. '5' Q3 3 Likert responses are not continuous (i.e., there are no actual decimal points in Likert responses), and they are constrained at their ends (i.e., 1-5 is the range in the figure above; there are no responses below the value of 1 or above the value of 5). The problem usually is to devise operations for equalizing the units of the scales - a problem not always easy of solution but one for which there are several possible modes of attack. 5.00.

Max. The central tendency concerns the averages of the values. Because respondents are presented with a range of possible answers, Likert scales are great for capturing the level of agreement or their feelings regarding the topic in a more nuanced way. Only occaionally is there concern for the location of a true zero point, because the human attributes measured by psychologists usually exist in a positive degree that is large compared with the range of its variation. Lastly, be sure to clearly state in your analysis whether you treat the data at interval level or at ordinal level. T-tests are not appropriate to use with ordinal data.

One thing that it is very important to keep track of, is whether a variable is continuous (truly numerical) or categorical (or "nominal"). It is believed that most people can think about or visualize 5 or 7 ordered options easily. Consider meaningfulness when considering the use of descriptive statistics.
