2. Ordinal
3. Interval
4. Ratio

Answer 1

Answer:

1. Nominal

Explanation:

In statistics, nominal level of measurement, numbers or letters are simply used in labeling or categorizing responses that have no numerical value or are not quantitative. These numbers or letters are simply tags or labels which identify items. Nominal level of measurement is usually used for variables that are qualitative rather than quantitative. The letters assigned to each response in the variable "race" have no value, but are mainly used as labels in categorizing the responses given by respondents, and in effect, the responses do not follow any order.

Therefore, the variable "race" exist at the nominal level of measurement.
