Furthermore, what type of data is time? **Ratio** data is **interval** data with a natural zero point. For example, time is **ratio** since 0 time is meaningful. Degrees Kelvin has a 0 point (absolute 0) and the steps in both these scales have the same degree of magnitude.

Moreover, are postcodes nominal or ordinal?

**Ordinal** numbers indicate the order or rank of things in a set (e.g., sixth in line; fourth place). **Nominal** numbers name or identify something (e.g., a zip code or a player on a team.) They do not show quantity or rank.
