Psychologist known for developing four levels of measurement

A sub-type of nominal scale with only categories (e.g. male/female)

Are typically measures of non-numeric concepts like satisfaction, happiness, discomfort, etc.

Are the ultimate nirvana when it comes to data measurement scales because they tell us about the order, they tell us the exact value between units.

Are numeric scales in which we know both the order and the exact differences between the values. The classic example of an interval scale is Celsius temperature because the difference between each value is the same.

Are used for labeling variables, without any quantitative value and could simply be called “labels.”
