Advantages
It divides values into subcategories based on their magnitude. Students' attitudes regarding a school program, for example, might be classified as highly effective, effective, or not effective. Ordinal scales include the standard 5- or 7-point Likert scale. In social sciences, the usage of a Likert scale is fairly widespread.
This scale allows for more study in psychology and other social sciences.
Disadvantages
This scale arranges the data in a logical order, but it does not quantify the link between sub-categories.
Arithmetic and statistical processes are not possible due to the lack of comparable distances between scale points.
An examination of the ordinal scale
On ordinal scale measures, the researcher can use median and mode, but not mean or standard deviation. Because data on an ordinal scale is ordered in descending or ascending order, the median can be used. This data arrangement allows you to identify the data's median, which is where the majority of the values are found. In the case of nominal scale, however, because the data is not ordered in any particular order, the median cannot be used. A median can't be employed in any other mathematical computations, hence it's useless for statistical analysis. The nominal and ordinal scale modes can both be computed, however only the nominal scale mode can be calculated.
