This absence of a standard unit means that mathematical operations like addition, subtraction, or calculating a true average are statistically inappropriate. However, the designer must be cautious about implying mathematical precision.
Graphical representations such as medians and interquartile ranges in box plots are often more informative than means when visualizing central tendency and dispersion. Unlike nominal data, the values on this scale communicate not just distinct categories but also the relative positioning or ranking of those categories concerning one another.
