The Ordinal scale includes statistical data type where variables are in order or rank but without a degree of difference between categories. In the ordinal level of measurement, the variables are still classified into categories, but these categories are ordered and there is no equivalent distance between the categories. Well recap briefly here, but for a full explanation, refer back tosection five. Many statistics, such as mean and standard deviation, do not make sense to compute with qualitative variables.

Beyond that, knowing the measurement scale for your variables doesnt really help you plan your analyses or interpret the results. The Interval scale quantifies the difference between two variables whereas the other two scales are solely capable of associating qualitative values with variables. For example, a person who is 20 years old has lived (since birth) half as long as a person who is 40 years old. Is birth month nominal ordinal interval or ratio?
