The Thurstone scale is an ordinal scale, which means it can rank items or scores but does not quantify the difference between them. Therefore, we can conclude that a higher score indicates a higher level of the trait being measured (in this case, creativity), but we cannot make conclusions about the ratio of those levels (e.g., twice as creative, three times as creative).
