Question

select all the levels of measurement for which data can be qualitative.
a. nominal
b. interval
c. ordinal
d. ratio

Explanation:

Nominal and ordinal levels can have qualitative data. Nominal data uses labels like gender (male/female). Ordinal data has an order but the differences are not meaningful, like rankings (low - medium - high). Interval and ratio levels are quantitative as they involve numerical values with meaningful differences and in the case of ratio, a true zero.

Answer:

A. Nominal
