  • Note 1 to entry: 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.
