Question

multiple choice question
the nominal level of data describes what type of information?
data that can be ranked in order.
data that can be measured using a continuous variable.
observations of a qualitative variable that can only be classified and counted.
observations of a quantitative variable where differences between measures are constant in size.

Explanation:

Nominal data is the lowest level of measurement, consisting of qualitative (categorical) data that can only be grouped into distinct categories and counted, with no inherent order, numerical measurement, or consistent differences between groups. The other options describe ordinal (ranked), ratio/interval (continuous measured), and interval (constant differences) data respectively.

Answer:

Observations of a qualitative variable that can only be classified and counted.
