…An interval scale is a scale in which the difference in values is meaningful (for example, temperature expressed in degrees Celsius), and a ratio scale is an interval scale with an absolute origin (for example, temperature expressed in degrees Kelvin). There are other scales, such as the ordinal scale (for example, the ranking of heights), in which the size is meaningless but the relationship between values is meaningful, and the nominal scale (for example, postal code), in which the size or relationship between values is meaningless even if they are expressed numerically, such as gender or occupation. When factors that characterize an object are given not as quantitative variables but as qualitative data with an ordinal or nominal scale, there are methods that allow for quantitative evaluation and classification, such as quantification type III and type IV of quantification theory, small scale analysis (SSA), and multidimensional scaling. … *Some terminology explanations that mention "nominal scale" are listed below.
