Scale

Home / glossary / Scale

Scale — ordered set of values, continuous or discrete, or a set of categories to which the attribute is mapped.

The type of scale depends on the nature of the relationship between values on the scale. Four types of scale are commonly defined:

  • nominal: the measurement values are categorical;
  • ordinal: the measurement values are rankings;
  • interval: the measurement values have equal distances corresponding to equal quantities of the attribute;
  • ratio: the measurement values have equal distances corresponding to equal quantities of the attribute, where the value of zero corresponds to none of the attribute.

These are just examples of the types of scale.
