A variable has one of four different levels of measurement: Nominal, Ordinal, Interval, or Ratio. (Interval and Ratio levels of measurement are sometimes called Continuous or Scale).
What are the four levels of measurement define each and give examples?
There are 4 levels of measurement, which can be ranked from low to high:
- Nominal: the data can only be categorized.
- Ordinal: the data can be categorized and ranked.
- Interval: the data can be categorized and ranked, and evenly spaced.
- Ratio: the data can be categorized, ranked, evenly spaced and has a natural zero.
