Document Summary
Nominal: numbers assigned to categories to signify qualitative differences. Basically: nominal figures simply tell us that two things are different, generated by assigning numbers arbitrarily to categories, they have no bearing to any scale, objective, or subjective, numbers can be replaced by another code. In research, used whenever we code items by categories. Ordinal: numbers assigned to categories to signify preferences. Basically: ordinal figures tell use two things are different, and one is better in some way, generated by assigning numbers to categories using a subjective scale lacking fixed intervals. Culture, rankings assigned to songs, tv shows, movies. Interval: numbers assigned to categories based on a fixed scale with equal intervals between points. Interval figures say two things are different, that one is better in some way, and the difference is measurable: generated by measurement against a fixed scale, example.
