In Statistics there are several measuring types:
These are predetermined categories and they can’t be sorted. An example would be Political Parties.
These types of data can be sorted by they lack a sense of scale. An example would be a form with options, “Love it, It’s ok, Dislike it, No Opinion.”
An interval type has a scale, but doesn’t have a floor. Data in this type can extend from a negative range through to a positive. An example could be a Bank Account, or the Temperature.
This data type is one in which there is a real floor (or start point.) Examples would be Height, Speed in MPH, etc.
